If CONTRACTOR and OWNER are unable to agree on entitlement to or the amount or extent of any adjustments in the Contract Price or the Contract Times as a result of any delay in OWNER's furnishing these lands, rights-of-way or easements, the CONTRACTOR may make a claim therefore as provided in Articles 11 and 12. The CONTRACTOR shall provide for all additional lands and access thereto that may be required for temporary construction facilities or storage of materials and equipment. Physical Conditions: 4.2.1. Explorations and Reports: Reference is made to the Supplementary Conditions for identification of those reports of explorations and tests of subsurface conditions at or contiguous to the site that have been utilized in preparing the Contract Documents and those drawings of physical conditions in or relating to existing surface or subsurface structures at or contiguous to the site (except Underground Facilities) that have been utilized in preparing the Contract Documents. 4.2.2. CONTRACTOR may rely upon the general accuracy of the "technical data" contained in such reports and drawings. Such "technical data" is identified in the Supplementary Conditions. Except for such reliance on such "technical data," CONTRACTOR may not rely upon or make any claim against OWNER, PROFESSIONAL, or any of PROFESSIONAL's Consultants with respect to: 4.2.2.1. the completeness of such reports and drawings for CONTRACTOR's purposes, including but not limited to, any aspects of the means, methods, techniques, sequences and procedures of construction to be employed by CONTRACTOR and safety precautions and programs incident thereto, or 4.2.2.2. other data, interpretations, opinions and information contained in such reports or shown or indicated in such drawings, or 4.2.2.3. any CONTRACTOR interpretation of or conclusion drawn from any "technical data" or any such data, interpretations, opinions or information. 4.2.3. If conditions are encountered, excluding existing utilities, at the site which are (1) subsurface or otherwise concealed physical conditions which differ materially from those indicated in the Contract Documents or (2) unknown physical conditions of an unusual nature, which differ materially from those ordinarily found to exist and generally recognized as inherent in construction activities of the character provided for in the Contract Documents, then CONTRACTOR shall give OWNER notice thereof promptly before conditions are disturbed and in no event later than 48 hours after first observance of the conditions. 4.2.4. The OWNER and PROFESSIONAL shall promptly investigate such conditions, and, if they differ materially and cause an increase or decrease in CONTRACTOR's cost of, or time required for, performance of any part of the Work, the OWNER and PROFESSIONAL shall recommend an equitable adjustment in the Contract Price or Contract Time, or both. If the OWNER and PROFESSIONAL determine that the conditions at the Site are not materially different from those indicated in the Contract Documents or are not materially GC-8 different from those ordinarily found and that no change in the terms of the Contract is justified, the PROFESSIONAL shall notify CONTRACTOR of the determination in writing. The Work shall be performed after direction is provided by the PROFESSIONAL. Physical Conditions - Underground Facilities: 4.3.1. Shown or Indicated: The information and data shown or indicated in the Contract Documents with respect to existing Underground Facilities at or contiguous to the site is based on information and data furnished to OWNER or PROFESSIONAL by OWNER'S of such Underground Facilities or by others. Unless it is otherwise expressly provided in the Supplementary Conditions: 4.3.1.1. OWNER and PROFESSIONAL shall not be responsible for the accuracy or completeness of any such information or data; and 4.3.1.2. The cost of all of the following will be included in the Contract Price and CONTRACTOR shall have full responsibility for reviewing and checking all such information and data for locating all Underground Facilities shown or indicated in the Contract Documents, for coordination of the Work with the OWNER'S of such Underground Facilities during construction, for the safety and protection thereof as provided in paragraph 6.20 and repairing any damage thereto resulting from the Work, the cost of all of which will be considered as having been included in the Contract Price. 4.3.2. Not Shown or Indicated. If an Underground Facility is uncovered or revealed at or contiguous to the site which was not shown or indicated in the Contract Documents and which CONTRACTOR could not reasonably have been expected to be aware of, CONTRACTOR shall, promptly after becoming aware thereof and before performing any Work affected thereby except in an emergency as permitted by paragraph 6.22, identify the OWNER of such Underground Facility and give written notice thereof to that OWNER and to OWNER and PROFESSIONAL. PROFESSIONAL will promptly review the Underground Facility to determine the extent to which the Contract Documents should be modified to reflect and document the consequences of the existence of the Underground Facility, and the Contract Documents will be amended or supplemented to the extent necessary. During such time, CONTRACTOR shall be responsible for the safety and protection of such Underground Facility as provided in paragraph 6.20. CONTRACTOR shall be allowed an increase in the Contract Price or an extension of the Contract Time, or both, to the extent that they are attributable to the existence of any Underground Facility that was not shown or indicated in the Contract Documents and which CONTRACTOR could not reasonably have been expected to be aware of. If the parties are unable to agree as to the amount or length thereof, CONTRACTOR may make a claim therefore as provided in Articles 11 and 12. Reference Points: 4.4. OWNER shall provide Engineering surveys to establish reference points for construction which in PROFESSIONAL's judgment are necessary to enable CONTRACTOR to proceed with the Work. CONTRACTOR shall be responsible for laying out the Work (unless otherwise specified in the General Requirements), shall protect and preserve the established reference points and shall make no changes or relocations without the prior written approval of OWNER.

OWNER shall not be responsible for any such materials brought to the site by CONTRACTOR, Subcontractor, Suppliers or anyone else for whom CONTRACTOR is responsible. 4.6 CONTRACTOR shall immediately: (i) stop all work in connection with such hazardous condition and in any area affected thereby (except in an emergency as required by 6.22), and (ii) notify OWNER and PROFESSIONAL (and thereafter confirm such notice in writing). OWNER shall promptly consult with PROFESSIONAL concerning the necessity for OWNER to retain a qualified expert to evaluate such hazardous condition or take corrective action, if any. CONTRACTOR shall not be required to resume Work in connection with such hazardous condition or in any such affected area until after OWNER has obtained any required permits related thereto and delivered to CONTRACTOR special written notice (i) specifying that such condition and any affected area is or has been rendered safe for the resumption of Work, or (ii) specifying any special conditions under which such Work may be resumed safely. If OWNER and CONTRACTOR cannot agree as to entitlement to or the amount or extent of an adjustment, if any, in Contract Price or Contract Times as a result of such Work stoppage or such special conditions under which Work is agreed by CONTRACTOR to be resumed, either party may make a claim therefore as provided in Articles 11 and 12. 4.7 If after receipt of such special written notice, CONTRACTOR does not agree to resume such Work based on a reasonable belief it is unsafe, or does not agree to resume such Work under such special conditions, then CONTRACTOR may order such portion of the Work that is in connection with such hazardous conditions or in such affected area to be deleted from the Work. If OWNER and CONTRACTOR cannot agree as to entitlement to or the amount or extent of an adjustment, if any, in Contract Price or Contract Times as a result of deleting such portion of the Work, then either party may make a claim therefore as provided in Articles 11 and 12. OWNER may have deleted such portion of the Work performed by OWNER's own forces or others in accordance with Article 7. 4.7.1 The provisions of 4.2 and 4.3 are not intended to apply to Asbestos, PCBs, Petroleum, Hazardous Waste or Radioactive Material uncovered or revealed at the site.

OWNER's Liability Insurance: 5.5. OWNER shall be responsible for purchasing and maintaining OWNER's own liability insurance, and/ or Risk Retention Program, and, at OWNER's option, may purchase and maintain such insurance as will protect OWNER against claims which may arise from operations under the Contract Documents. Property Insurance: 5.6. Unless otherwise provided in the Supplementary Conditions, OWNER shall purchase and maintain property insurance upon the Work at the site to the full insurable value thereof (subject to such deductible amounts as may be provided in the Supplementary Conditions or required by Laws and Regulations). This insurance shall include the interests of OWNER, CONTRACTOR, Subcontractors, PROFESSIONAL and GC-12 PROFESSIONAL's consultants in the Work, all of whom shall be listed as insureds or additional insured parties, shall insure against the perils of fire and extended coverage and shall include "all risk" insurance for physical loss and damage including theft, vandalism and malicious mischief, collapse and water damage, and such other perils as may be provided in the Supplementary Conditions, and shall include damages, losses and expenses arising out of or resulting from any insured loss or incurred in the repair or replacement of any insured property (including but not limited to fees and charges of PROFESSIONALs, architects, attorneys and other PROFESSIONALs).

Prior to commencement of the Work at the site, OWNER shall in writing advise CONTRACTOR whether or not such other insurance has been procured by OWNER. Waiver of Rights: 5.11.1. OWNER and CONTRACTOR waive all rights against each other for all losses and damages caused by any of the perils covered by the policies of insurance provided in response to paragraphs 5.6 and 5.7 and other property insurance applicable to the Work, and also waive all such rights against the Subcontractors, PROFESSIONAL, PROFESSIONAL's consultants and all other parties named as insureds in such policies for losses and damages so caused. As required by paragraph 6.11, each subcontract between CONTRACTOR and a Subcontractor will contain similar waiver provisions by the Subcontractor in favor of OWNER, CONTRACTOR, PROFESSIONAL, PROFESSIONAL's consultants and all other parties named as insureds. None of the above waivers shall extend to the rights that any of the insured parties may have to the proceeds of insurance held by OWNER as trustee or otherwise payable under any policy so issued.

Indemnification 5.16.1. CONTRACTOR shall indemnify and hold harmless OWNER, and its employees and agents from and against all liabilities, claims, suits, demands, damages, losses, and expenses, including attorneys' fees, arising out of or resulting from the performance of its Work, provided that any such liability, claim, suit, demand, damage, loss, or expense (a) is attributable to bodily injury, sickness, disease or death, or injury to or destruction of tangible property, including the loss of use resulting therefrom and (b) is caused in whole or in part by an act or omission of CONTRACTOR, any Subcontractor, anyone directly or indirectly employed by any of them, or anyone for whose acts any of them may be liable, whether or not it is caused in whole or in part by the negligence or other fault of a party indemnified hereunder. 5.16.2.

CONTRACTOR shall be responsible to see that the finished Work complies accurately with the Contract Documents. 6.2. CONTRACTOR shall keep on the Work, at all times during its progress, a competent resident superintendent, who shall not be replaced without written notice to OWNER and PROFESSIONAL except under extraordinary circumstances. The superintendent will be CONTRACTOR's representative at the site and shall have authority to act on behalf of CONTRACTOR. All communications to the superintendent shall be as binding as if given to CONTRACTOR. Labor, Materials and Equipment: 6.3. CONTRACTOR shall provide competent, suitably qualified personnel to survey and layout the Work and perform construction as required by the Contract Documents. CONTRACTOR shall at all times maintain good discipline and order at the site. Except in connection with the safety or protection of persons or the Work or property at the site or adjacent thereto, and except as otherwise indicated in the Contract Documents, all Work at the site shall be performed during regular working hours, and CONTRACTOR will not permit evening work or the performance of Work on Saturday, Sunday or any legal holiday without OWNER's written consent given after prior written notice to PROFESSIONAL. 6.4. Unless otherwise specified in the General Requirements, CONTRACTOR shall furnish and assume full responsibility for all materials, equipment, labor, transportation, construction equipment and machinery, tools, appliances, fuel, power, light, heat, telephone, water, sanitary facilities, temporary facilities and all other facilities and incidentals whether temporary or permanent necessary for the execution, testing, initial operation, and completion of the Work as required by the Contract Documents. 6.5. All materials and equipment shall be of good quality and new, except as otherwise provided in the Contract Documents. If required by PROFESSIONAL, CONTRACTOR shall furnish satisfactory evidence (including reports of required tests) as to the kind and quality of materials and equipment. All materials and equipment shall be applied, installed, connected, erected, used, cleaned and conditioned in accordance with the instructions of the applicable Supplier except as otherwise provided in the Contract Documents; but no provision of any such instructions will be effective to assign to PROFESSIONAL, or any of PROFESSIONAL's consultants, agents or employees, any duty or authority to supervise or direct the furnishing or performance of the Work or any duty or authority to undertake responsibility contrary to the provisions of paragraph 9.14 or 9.15. Adjusting Progress Schedule: 6.6. CONTRACTOR shall submit to PROFESSIONAL for acceptance to the extent indicated in paragraph 2.9 adjustments in the progress schedule to reflect the impact thereon of new developments; these will conform GC-16 generally to the progress schedule then in effect and additionally will comply with any provisions of the General Requirements applicable thereto. Substitutes or "Or-Equal" Items: 6.7.1. Whenever materials or equipment are specified or described in the Contract Documents by using the name of a proprietary item or the name of a particular Supplier, the naming of the item is intended to establish the type, function and quality required. Unless the name is followed by words indicating that no substitution is permitted, materials or equipment of other Suppliers may be accepted by PROFESSIONAL if sufficient information is submitted by CONTRACTOR to allow PROFESSIONAL to determine that the material or equipment proposed is equivalent or equal to that named. The procedure for review by PROFESSIONAL will include the following as supplemented in the General Requirements. Requests for review of substitute items of material and equipment will not be accepted by PROFESSIONAL from anyone other than CONTRACTOR. If CONTRACTOR wishes to furnish or use a substitute item of material or equipment, CONTRACTOR shall make written application to PROFESSIONAL for acceptance thereof, certifying that the proposed substitute will perform adequately the functions and achieve the results called for by the general design, be similar and of equal substance to that specified and be suited to the same use as that specified. The application will state that the evaluation and acceptance of the proposed substitute will not prejudice CONTRACTOR's achievement of Substantial Completion on time, whether or not acceptance of the substitute for use in the Work will require a change in any of the Contract Documents (or in the provisions of any other direct contract with OWNER for work on the Project) to adapt the design to the proposed substitute and whether or not incorporation or use of the substitute in connection with the Work is subject to payment of any license fee or royalty. All variations of the proposed substitute from that specified will be identified in the application and available maintenance, repair and replacement service will be indicated. The application will also contain an itemized estimate of all costs that will result directly or indirectly from acceptance of such substitute, including costs of redesign and claims of other contractors affected by the resulting change, all of which shall be considered by PROFESSIONAL. In evaluating the proposed substitute, PROFESSIONAL may require CONTRACTOR to furnish, at CONTRACTOR's expense, additional data about the proposed substitute. 6.7.2. If a specific means, method, technique, sequence or procedure of construction is indicated in or required by the Contract Documents, CONTRACTOR may furnish or utilize a substitute means, method, sequence, technique or procedure of construction acceptable to PROFESSIONAL, if CONTRACTOR submits sufficient information to allow PROFESSIONAL to determine that the substitute proposed is equivalent to that indicated or required by the Contract Documents. The procedure for review by PROFESSIONAL will be similar to that provided in paragraph 6.7.1 as applied by PROFESSIONAL and as may be supplemented in the General Requirements. 6.7.3. PROFESSIONAL will be allowed a reasonable time within which to evaluate each proposed substitute. PROFESSIONAL will be the sole judge of acceptability and no substitute will be ordered, installed or utilized without PROFESSIONAL's prior written acceptance which will be evidenced by either a Change Order or an approved Shop Drawing. OWNER may require CONTRACTOR to furnish, at CONTRACTOR's expense, a special performance guarantee or other surety with respect to any substitute. PROFESSIONAL will record time required by PROFESSIONAL and PROFESSIONAL's consultants in evaluating substitutions proposed by CONTRACTOR and in making changes in the Contract Documents occasioned thereby. Whether or not PROFESSIONAL accepts a proposed substitute, CONTRACTOR shall reimburse OWNER for the charges of PROFESSIONAL and PROFESSIONAL's consultants for evaluating each proposed substitute. GC-17 Concerning Subcontractors, Suppliers and Others: 6.8.1. CONTRACTOR shall not employ any Subcontractor, Supplier or other person or organization (including those acceptable to OWNER and PROFESSIONAL as indicated in paragraph 6.8.2) whether initially or as a substitute, against whom OWNER or PROFESSIONAL may have reasonable objection. CONTRACTOR shall not be required to employ any Subcontractor, Supplier or other person or organization to furnish or perform any of the Work against whom CONTRACTOR has reasonable objection. 6.8.2. If the Supplementary Conditions require the identity of certain Subcontractors, Suppliers or other persons or organizations including those who are to furnish the principal items of materials and equipment to be submitted to OWNER prior to the Effective Date of the Agreement for acceptance by OWNER and PROFESSIONAL and if CONTRACTOR has submitted a list thereof in accordance with the Supplementary Conditions, OWNER's or PROFESSIONAL's acceptance (either in writing or by failing to make written objection thereto by the date indicated for acceptance or objection in the bidding documents or the Contract Documents) of any such Subcontractor, Supplier or other person or organization so identified may be revoked on the basis of reasonable objection after due investigation, in which case CONTRACTOR shall submit an acceptable substitute, the Contract Price will be increased by the difference, and the cost occasioned by such substitution and an appropriate Change Order will be issued or Written Amendment signed. No acceptance by OWNER or PROFESSIONAL of any such Subcontractor, Supplier or other person or organization shall constitute a waiver of any right of OWNER or PROFESSIONAL to reject defective Work. 6.9. CONTRACTOR shall be fully responsible to OWNER and PROFESSIONAL for all acts and omissions of the Subcontractors, Suppliers and other persons and organizations performing or furnishing any of the Work under a direct or indirect contract with CONTRACTOR just as CONTRACTOR is responsible for CONTRACTOR's own acts and omissions. Nothing in the Contract Documents shall create any contractual relationship between OWNER or PROFESSIONAL and any such Subcontractor, Supplier or other person or organization, nor shall it create any obligation on the part of OWNER or PROFESSIONAL to payor to see to the payment of any moneys due any such Subcontractor, Supplier or other person or organization except as may otherwise be required by Laws and Regulations. 6.10. The divisions and sections of the Specifications and the identifications of any Drawings shall not control CONTRACTOR in dividing the Work among Subcontractors or Suppliers or delineating the Work to be performed by any specific trade. 6.11.

Permits: 6.13. CONTRACTOR shall obtain and pay for all construction permits, licenses, governmental charges and inspection fees, and all public utility charges which are applicable and necessary for the execution of the Work. All permit costs shall be included in the base bid. Permits, if any, that are provided and paid for by OWNER are listed in the Supplementary Conditions. Any delays associated with the permitting process will be considered for time extensions only and no damages or additional compensation for delay will be allowed. Laws and Regulations: 6.14.1. CONTRACTOR shall give all notices and comply with all Laws and Regulations applicable to furnishing and performance of the Work. Except where otherwise expressly required by applicable Laws and Regulations, neither OWNER nor PROFESSIONAL shall be responsible for monitoring CONTRACTOR's compliance with any Laws or Regulations. 6.14.2. If CONTRACTOR observes that any of the Contract Documents are contradictory to such laws, rules, and regulations, it will notify the Project Manager promptly in writing. Any necessary changes shall then be adjusted by an appropriate Change Order. If CONTRACTOR performs any Work that it knows or should have known to be contrary to such laws, ordinances, rules, and regulations and without such notice to the Project Manager, it shall bear all related costs. Taxes: 6.15. CONTRACTOR shall pay all sales, consumer, use and other similar taxes required to be paid in accordance with the Laws and Regulations of the place of the Project which are applicable during the performance of the Work. Use of Premises: 6.16.

CONTRACTOR shall not unreasonably encumber the premises with construction equipment or other materials or equipment. Any loss or damage to CONTRACTOR's or any Subcontractor's equipment is solely at the risk of CONTRACTOR. CONTRACTOR shall assume full responsibility for any damage to any such land or area, or to the OWNER or occupant thereof or of any land or areas contiguous thereto, resulting from the performance of the Work. Should any claim be made against OWNER or PROFESSIONAL by any such OWNER or occupant because of the performance of the Work, CONTRACTOR shall promptly attempt to settle with such other party by agreement or otherwise resolve the claim by arbitration or at law. CONTRACTOR shall, to the fullest extent permitted by Laws and Regulations, indemnify and hold OWNER GC-19 harmless from and against all claims, damages, losses and expenses (including, but not limited to, fees of PROFESSIONALs, architects, attorneys and other professionals and court and arbitration costs) arising directly, indirectly or consequentially out of any action, legal or equitable, brought by any such other party against OWNER to the extent based on a claim arising out of CONTRACTOR's performance of the Work. 6.17. During the progress of the Work, CONTRACTOR shall keep the premises free from accumulations of waste materials, rubbish and other debris or contaminants resulting from the Work. At the completion of the Work, CONTRACTOR shall remove all waste materials, rubbish and debris from and about the premises as well as all tools, appliances, construction equipment and machinery, and surplus materials, and shall leave the site clean and ready for occupancy by OWNER. CONTRACTOR shall restore to original condition all property not designated for alteration by the Contract Documents. 6.18. CONTRACTOR shall not load nor permit any part of any structure to be loaded in any manner that will endanger the structure, nor shall CONTRACTOR subject any part of the Work or adjacent property to stresses or pressures that will endanger them. Record Documents: 6.19. Contractor shall keep at the site and in good order one record copy of the Contract Documents and all Drawings and Specifications.

CONTRACTOR shall comply with all applicable Laws and Regulations of any public body having jurisdiction for the safety of persons or property or to protect them from damage, injury or loss; and shall erect and maintain all necessary safeguards for such safety and protection. CONTRACTOR shall notify OWNERs of adjacent property and of Underground Facilities and utility OWNERs when prosecution of the Work may affect them, and shall cooperate with them in the protection, removal, relocation and replacement of their property. All damage, injury or loss to any property referred to in paragraph 6.20.2 or 6.20.3 caused, directly or indirectly, in whole or in part, by CONTRACTOR, any Subcontractor, Supplier or any other person or GC-20 organization directly or indirectly employed by any of them to perform or furnish any of the Work or anyone for whose acts any of them may be liable, shall be remedied by CONTRACTOR (except damage or loss attributable to the fault of Drawings or Specifications or to the acts or omissions of OWNER or PROFESSIONAL or anyone employed by either of them or anyone for whose acts either of them may be liable, and not attributable, directly or indirectly, in whole or in part, to the fault or negligence of CON- TRACTOR). CONTRACTOR's duties and responsibilities for the safety and protection of the Work shall continue until such time as all the Work is completed and PROFESSIONAL has issued a notice to OWNER and CONTRACTOR in accordance, with paragraph 14.13 that the Work is acceptable (except as otherwise expressly provided in connection with Substantial Completion). 6.21. CONTRACTOR shall designate a responsible member of its organization whose duty shall be the prevention of accidents at the site. This person shall be CONTRACTOR's superintendent unless otherwise designated in writing by CONTRACTOR to the Project Manager. Emergencies: 6.22. In emergencies affecting the safety or protection of persons or the Work or property at the site or adjacent thereto, CONTRACTOR, without special instruction or authorization from PROFESSIONAL or OWNER, is obligated to act to prevent threatened damage, injury or loss. CONTRACTOR shall give PROFESSIONAL prompt written notice if CONTRACTOR believes that any significant changes in the Work or variations from the Contract Documents have been caused thereby. If PROFESSIONAL determines that a change in the Contract Documents is required because of the action taken in response to an emergency, a Work Change Directive or Change Order be issued to document the consequences of the changes or variations. 6.22.1. CONTRACTOR shall immediately notify PROFESSIONAL of all events involving injuries to any person on the Site, whether or not such person was engaged in the construction of the Project, and shall file a written report on such person(s) and any other event resulting in property damage of any amount within five (5) days of the occurrence. 6.22.2. If PROFESSIONAL determines that a change in the Contract Documents is required because of the action taken by CONTRACTOR in response to such an emergency, a Change Order will be issued to document the consequences of such action. Shop Drawings and Samples: 6.23. After checking and verifying all field measurements, CONTRACTOR shall promptly submit to PROFESSIONAL for approval, in accordance with the accepted schedule of submittals, all submittals and samples required by the Contract Documents. All submittals and samples shall have been checked by and stamped with the approval of CONTRACTOR and identified as PROFESSIONAL may require. The data shown on or with the submittals will be complete with respect to dimensions, design criteria, materials and any other information necessary to enable PROFESSIONAL to review the submittal as required. At the time of each submission, CONTRACTOR shall give notice to PROFESSIONAL of all deviations that the submittal or sample may have from the requirements of the Contract Documents. 6.24. PROFESSIONAL shall review and approve submittals and samples. Professional's review and approval shall be only for conformance with the design concept of the Project and compliance with the information GC-21 given in the Contract Documents. The approval of a separate item as such will not indicate approval of the assembly in which the item functions. CONTRACTOR will make any corrections required by PROFESSIONAL and resubmit the required number of corrected copies until approved. CONTRACTOR's stamp of approval on any submittal or sample shall constitute its representation to PROFESSIONAL and OWNER that CONTRACTOR has determined and verified all quantities, dimensions, field construction criteria, materials, catalog numbers, and similar data, and that each submittal or sample has been reviewed or coordinated with the requirements of the Work and the Contract Documents. 6.24.1. No Work requiring a submittal or sample submission shall commence until the submission has been approved by PROFESSIONAL. A copy of each approved submittal and each approved sample shall be kept in good order by CONTRACTOR at the site and shall be available to PROFESSIONAL and OWNER. Any delays associated with the submittal process will be considered for time extensions only, and no damages or additional compensation for delay will be allowed. 6.24.2. Before submission of each Shop Drawing or sample, CONTRACTOR shall have determined and verified all quantities, dimensions, specified performance criteria, installation requirements, materials, catalog numbers and similar data with respect thereto and reviewed or coordinated each Shop Drawing or sample with other Shop Drawings and samples and with the requirements of the Work and the Contract Documents. 6.24.3. At the time of each submission, CONTRACTOR shall give PROFESSIONAL specific written notice of each variation that the Shop Drawings or samples may have from the requirements of the Contract Documents, and, in addition, shall cause a specific notation to be made on each Shop Drawing submitted to PROFESSIONAL for review and approval of each such variation. 6.26. PROFESSIONAL will review and approve with reasonable promptness Shop Drawings and samples, but PROFESSIONAL's review and approval will be only for conformance with the design concept of the Project and for compliance with the information given in the Contract Documents and shall not extend to means, methods, techniques, sequences or procedures of construction (except where a specific means, method, technique, sequence or procedure of construction is indicated in or required by the Contract Documents) or to safety precautions or programs incident thereto. The review and approval of a separate item as such will not indicate approval of the assembly in which the item functions. 6.27. PROFESSIONAL's approval of submittals or samples shall not relieve CONTRACTOR from responsibility for any variation from the requirements of the Contract Documents unless CONTRACTOR has, in writing, called PROFESSIONAL's attention to each such variation at the time of submission and the OWNER has given written approval to the specific deviation; any such approval by PROFESSIONAL shall not relieve CONTRACTOR from responsibility for errors or omissions in the submittals. 6.28. Where a shop drawing or sample is required by the Contract Documents or the schedule of shop drawings and sample submissions accepted by PROFESSIONAL as required, any related work performed prior to PROFESSIONAL's review and approval of the pertinent submittal will be at the sole expense and responsibility of CONTRACTOR. GC-22 Continuing the Work: 6.30. CONTRACTOR shall carryon the Work and adhere to the progress schedule during all disputes or disagreements with OWNER. No Work shall be delayed or postponed pending resolution of any disputes or disagreements, except as permitted by paragraph 15.6 or as CONTRACTOR and OWNER may otherwise agree in writing. Cleaning Up: 6.31. CONTRACTOR shall maintain the site free from accumulations of waste materials, rubbish, and other debris or contaminants resulting from the work on a daily basis or as required. At the completion of the work, CONTRACTOR shall remove all waste materials, rubbish, and debris from the site as well as all tools, construction equipment and machinery, and surplus materials and will leave the Site clean and ready for occupancy by OWNER. All disposal shall be in accordance with applicable Laws and Regulations. In addition to any other rights available to OWNER under the Contract Documents, CONTRACTOR's failure to maintain the site may result in withholding of any amounts due CONTRACTOR. CONTRACTOR will restore to original condition those portions of the site not designated for alteration by the Contract Documents. Indemnification: 6.32. To the fullest extent permitted by Laws and Regulations, CONTRACTOR shall indemnify and hold harmless OWNER and PROFESSIONAL and their consultants, agents and employees from and against all claims, damages, losses and expenses, direct, indirect or consequential (including but not limited to fees and charges of PROFESSIONALs, architects, attorneys and other PROFESSIONALs and court and arbitration costs) arising out of or resulting from the performance of the Work, provided that any such claim, damage, loss or expense (a) is attributable to bodily injury, sickness, disease or death, or to injury to or destruction of tangible property (other than the Work itself) including the loss of use resulting therefrom and (b) is caused in whole or in part by any negligent act or omission of CONTRACTOR, any Subcontractor, any person or organization directly or indirectly employed by any of them to perform or furnish any of the Work or anyone for whose acts any of them may be liable, regardless of whether or not it is caused in part by a party indemnified hereunder or arises by or is imposed by Law and Regulations regardless of the negligence of any such party. 6.33. In any and all claims against OWNER or PROFESSIONAL or any of their consultants, agents or employees by any employee of CONTRACTOR, any Subcontractor, any person or organization directly or indirectly employed by any of them to perform or furnish any of the Work or anyone for whose acts any of them may be liable, the indemnification obligation under paragraph 6.32 shall not be limited in any way by any limitation on the amount or type of damages, compensation or benefits payable by or for CONTRACTOR or any such Subcontractor or other person or organization under workers' or workmen's compensation acts, disability benefit acts or other employee benefit acts. 6.34. The obligations of CONTRACTOR under paragraph 6.32 shall not extend to the liability of PROFESSIONAL, PROFESSIONAL's consultants, agents or employees arising out of the preparation or approval of maps, drawings, opinions, reports, surveys, Change Orders, designs or specifications. GC-23 ARTICLE 7---0THER WORK Related Work at Site: 7.1. OWNER may perform other work related to the Project at the site by OWNER's own forces, have other work performed by aided OWNERs or let other direct contracts therefore which shall contain General Conditions similar to these. If the fact that such other work is to be performed was not noted in the Contract Documents, written notice thereof will be given to CONTRACTOR prior to starting any such other work, and, if CONTRACTOR believes that such performance will involve additional expense to CONTRACTOR or requires additional time and the parties are unable to agree as to the extent thereof, CONTRACTOR may make a claim therefore as provided in Articles 11 and 12. 7.1.2. CONTRACTOR shall afford each utility OWNER and other contractor who is a party to such a direct contract for OWNER, if OWNER is performing the additional work with OWNER's employees, proper and safe access to the site and a reasonable opportunity for the introduction and storage of materials and equipment and the execution of such work, and shall properly connect and coordinate the Work with theirs. CONTRACTOR shall do all cutting, fitting and patching of the Work that may be required to make its several parts come together properly and integrate with such other work. CONTRACTOR shall not endanger any work of others by cutting, excavating or otherwise altering their work and will only cut or alter their work with the written consent of PROFESSIONAL and the others whose work will be affected. The duties and responsibilities of CONTRACTOR under this paragraph are for the benefit of such utility OWNERs and other contractors to the extent that there are comparable provisions for the benefit of CONTRACTOR in said direct contracts between OWNER and such utility OWNERs and other contractors. 7.2. If any part of CONTRACTOR's Work depends for proper execution or results upon the work of any such other contractor or utility OWNER (or OWNER), CONTRACTOR shall inspect and promptly report to PROFESSIONAL in writing any delays, defects or deficiencies in such work that render it unavailable or unsuitable for such proper execution and results. CONTRACTOR's failure so to report will constitute an acceptance of the other work as fit and proper for integration with CONTRACTOR's Work except for latent or nonapparent defects and deficiencies in the other work. Coordination: 7.4. If OWNER contracts with others for the performance of other work on the Project at the site, the person or organization who will have authority and responsibility for coordination of the activities among the various prime contractors will be identified in the Supplementary Conditions, and the specific matters to be covered by such authority and responsibility will be itemized, and the extent of such authority and responsibilities will be provided in the Supplementary Conditions. Unless otherwise provided in the Supplementary Conditions, neither OWNER nor PROFESSIONAL shall have any authority or responsibility in respect of such coordination. GC-24 ARTICLE 8---0WNER'S RESPONSIBILITIES 8.1. Except as otherwise provided in these General Conditions, OWNER shall issue all communications to CONTRACTOR through the PROFESSIONAL. 8.2. In case of termination of the employment of PROFESSIONAL, OWNER shall appoint a PROFESSIONAL against whom CONTRACTOR makes no reasonable objection, whose status under the Contract Documents shall be that of the former PROFESSIONAL. Any dispute in connection with such appointment shall be subject to arbitration. 8.3. OWNER shall furnish the data required of OWNER under the Contract Documents promptly and shall make payments to CONTRACTOR promptly after they are due as provided in paragraphs 14.4 and 14.13. 8.4. OWNER's duties in respect of providing lands and easements and providing Engineering surveys to establish reference points are set forth in paragraphs 4.1 and 4.4. Paragraph 4.2 refers to OWNER's identifying and making available to CONTRACTOR copies of reports of explorations and tests of subsurface conditions at the site and in existing structures which have been utilized by PROFESSIONAL in preparing the Drawings and Specifications. 8.5. OWNER's responsibilities in respect of purchasing and maintaining liability and property insurance are set forth in paragraphs 5.5 through 5.8. 8.6. OWNER is obligated to execute Change Orders as indicated in paragraph 10.3. 8.7. OWNER's responsibility in respect of certain inspections, tests and approvals is set forth in paragraph 13.4. 8.8. In connection with OWNER's right to stop Work or suspend Work, see paragraphs 13.10 and 15.1. Paragraph 15.2 deals with OWNER's right to terminate services of CONTRACTOR under certain circumstances. GC-25 ARTICLE 9---PROFESSIONAL'S STATUS DURING CONSTRUCTION OWNER's Representative: 9.1. PROFESSIONAL will be OWNER's representative during the construction period. The duties and responsibilities and the limitations of authority of PROFESSIONAL as OWNER's representative during construction are set forth in the Contract Documents and shall not be extended without written consent of OWNER and PROFESSIONAL. Visits to Site: 9.2. PROFESSIONAL will make visits to the site at intervals appropriate to the various stages of construction to observe the premises and quality of the executed Work and to determine, in general, if the Work is proceeding in accordance with the Contract Documents. PROFESSIONAL will not be required to make exhaustive or continuous on-site inspections to check the quality or quantity of the Work. PROFESSIONAL's efforts will be directed toward providing for OWNER a greater degree of confidence that the completed Work will conform to the Contract Documents. On the basis of such visits and on-site observations as an experienced and qualified design PROFESSIONAL, PROFESSIONAL will keep OWNER informed of the progress of the Work and will endeavor to guard OWNER against defects and deficiencies in the Work. Project Representation: 9.3. If OWNER and PROFESSIONAL agree, PROFESSIONAL will furnish a Resident Project Representative to assist PROFESSIONAL in observing the performance of the Work. The duties, responsibilities and limitations of authority of any such Resident Project Representative and assistants will be as provided in the Supplementary Conditions. If OWNER designates another agent to represent OWNER at the site who is not PROFESSIONAL's agent or employee, the duties, responsibilities and limitations of authority of such other person will be as provided in the Supplementary Conditions. Clarifications and Interpretations: 9.4. PROFESSIONAL shall issue such written clarifications or interpretations of the Contract Documents (in the form of Drawings or otherwise) as may be determined necessary, or as reasonably requested by CONTRACTOR, which shall be consistent with or reasonably inferable from the overall intent of the Contract Documents. If CONTRACTOR believes that a written clarification and interpretation entitles it to an increase in the Contract Price and/ or Contract Time, CONTRACTOR may make a claim as provided for in Articles 11 or 12. Authorized Variations in Work: 9.5. PROFESSIONAL may authorize minor variations in the Work from the requirements of the Contract Documents which do not involve an adjustment in the Contract Price or the Contract Time and are consistent with the overall intent of the Contract Documents. These may be accomplished by a Field Order and will be binding on OWNER and also on CONTRACTOR who shall perform the Work involved promptly. If CONTRACTOR believes that a Field Order justifies an increase in the Contract Price or an extension of the GC-26 Contract Time and the parties are unable to agree as to the amount or extent thereof, CONTRACTOR may make a claim therefore as provided in Article 11 or 12. Rejecting Defective Work: 9.6. PROFESSIONAL will have authority to disapprove or reject Work which PROFESSIONAL believes to be defective and will also have authority to require special inspection or testing of the Work as provided in paragraph 13.9, whether or not the Work is fabricated, installed or completed. Shop Drawings, Change Orders and Payments: 9.7. In connection with PROFESSIONAL's responsibility for Shop Drawings and samples, see paragraphs 6.23 through 6.29 inclusive. 9.8. In connection with PROFESSIONAL's responsibilities as to Change Orders, see Articles 10, 11 and 12. 9.9. In connection with PROFESSIONAL's responsibilities in respect of Applications for Payment, etc., see Article 14. Determinations for Unit Prices: 9.10. PROFESSIONAL will determine the actual quantities and classifications of Unit Price Work performed by CONTRACTOR. PROFESSIONAL will review with CONTRACTOR PROFESSIONAL's preliminary determinations on such matters before rendering a written decision thereon (by recommendation of an Application for Payment or otherwise). PROFESSIONAL's written decisions thereon will be final and binding upon OWNER and CONTRACTOR, unless, within ten days after the date of any such decision, either OWNER or CONTRACTOR delivers to the other party to the Agreement and to PROFESSIONAL written notice of intention to appeal from such a decision. Decisions on Disputes: 9.11. PROFESSIONAL will be the initial interpreter of the requirements of the Contract Documents and judge of the acceptability of the Work there under. Claims, disputes and other matters relating to the acceptability of the Work or the interpretation of the requirements of the Contract Documents pertaining to the performance and furnishing of the Work and claims under Articles 11 and 12 in respect of changes to the Contract Price or Contract Time will be referred initially to PROFESSIONAL in writing with a request for a formal decision in accordance with this paragraph, which PROFESSIONAL will render in writing within a reasonable time. Written notice of each such claim, dispute and other matter will be delivered by the claimant to PROFESSIONAL and the other party to the Agreement promptly (but in no event later than thirty days after the occurrence of the event giving rise thereto) and written supporting data will be submitted to PROFESSIONAL and the other party within sixty days after such occurrence unless PROFESSIONAL allows an additional period of time to ascertain more accurate data in support of the claim. 9.12. When functioning as interpreter and judge under paragraphs 9.10 and 9.11, PROFESSIONAL will not show partiality to OWNER or CONTRACTOR and will not be liable in connection with any interpretation or GC-27 decision rendered in good faith in such capacity. The rendering of a decision by PROFESSIONAL pursuant to paragraphs 9.10 and 9.11 with respect to any such claim, dispute or other matter (except any which have been waived by the making or acceptance of final payment as provided in paragraph 14.16) will be a condition precedent to any exercise by OWNER or CONTRACTOR of such rights or remedies as either may otherwise have under the Contract Documents or by Laws or Regulations in respect of any such claim, dispute or other matter. Limitations on PROFESSIONAL's Responsibilities: 9.13. Neither PROFESSIONAL's authority to act under this Article or elsewhere in the Contract Documents nor any decision made in good faith to exercise such authority shall give rise to any duty or responsibility of PROFESSIONAL to CONTRACTOR, any Subcontractor, any of their agents or employees. 9.14. PROFESSIONAL shall not be responsible for the construction means, methods, techniques, sequences, or procedures or the safety precautions and programs used. PROFESSIONAL shall not be responsible for CONTRACTOR's failure to perform the Work in accordance with the Contract Documents. 9.15. PROFESSIONAL shall not be responsible for the acts or omissions of CONTRACTOR, any Subcontractors, any agents or employees, or any other persons performing any of the Work. GC-28 ARTICLE lO--CHANGES IN THE WORK 10.1. Without invalidating the Contract, OWNER may at any time or from time to time order additions, deletions, or revisions in the Work. The OWNER shall provide CONTRACTOR with a proposal request, identifying the Work to be added, deleted or revised. Upon receipt, CONTRACTOR shall promptly submit a written proposal for the changed work prepared in accordance with Articles 11 and 12. If the proposal request calls only for the deletion of Work, the OWNER may order the partial suspension of any Work related to the proposed deletion, in which case CONTRACTOR must cease performance as directed; CONTRACTOR shall not be entitled to claim lost profits on deleted work. All changed Work shall be executed under the applicable conditions of the Contract Documents. 10.2. Additional Work performed by CONTRACTOR without authorization of a Change Order will not entitle CONTRACTOR to an increase in the Contract Price or an extension of the Contract Time, except in the case of an emergency as provided in Article 6. The effect of this paragraph shall remain paramount and shall prevail irrespective of any conflicting provisions contained in these Contract Documents. 10.3. Upon agreement as to changes in the Work to be performed, Work performed in an emergency as provided in Article 6, and any other claim of CONTRACTOR for a change in the Contract Time or the Contract Price, PROFESSIONAL will prepare a written Change Order to be signed by PROFESSIONAL and CONTRACTOR and submitted to OWNER for approval. 10.4. In the absence of an agreement as provided in 10.3, OWNER may, at its sole discretion, issue a Work Change Directive to CONTRACTOR. Pricing of the Work Change Directive will be in accordance with Section 11.3. The Work Change Directive will specify a price, and if applicable a time extension, determined to be reasonable by OWNER. If CONTRACTOR fails to sign such Work Change Directive; CONTRACTOR may submit a claim in accordance with Articles 11 and 12, but CONTRACTOR shall nevertheless be obligated to fully perform the work as directed by the Work Change Directive. 10.5. CONTRACTOR shall proceed diligently with performance of the Work as directed by OWNER, regardless of pending claim actions, unless otherwise agreed to in writing. 10.6. If notice of any change affecting the general scope of the Work or the provisions of the Contract Documents (including, but not limited to, Contract Price or Contract Time) is required by the provisions of any Bond to be given to a surety, the giving of any such notice will be CONTRACTOR's responsibility, and the amount of each applicable Bond will be adjusted accordingly. GC-29 ARTICLE ll-CHANGE OF CONTRACT PRICE 11.1. The Contract Price constitutes the total compensation (subject to written authorized adjustments) payable to CONTRACTOR for performing the Work. All duties, responsibilities and obligations assigned to or undertaken by CONTRACTOR shall be at CONTRACTOR's expense without change in the Contract Price. 11.2. The Contract Price may only be changed by a Change Order or by a Written Amendment. Any claim for an increase or decrease in the Contract Price shall be based on written notice delivered by the party making the claim to the other party and to PROFESSIONAL promptly (but in no event later than thirty days) after the occurrence of the event giving rise to the claim and stating the general nature of the claim. Notice of the amount of the claim with supporting data shall be delivered within sixty days after such occurrence (unless PROFESSIONAL allows an additional period of time to ascertain more accurate data in support of the claim) and shall be accompanied by claimant's written statement that the amount claimed covers all known amounts (direct, indirect and consequential) to which the claimant is entitled as a result of the occurrence of said event. All claims for adjustment in the Contract Price shall be determined by PROFESSIONAL in accordance with paragraph 9.11 if OWNER and CONTRACTOR cannot otherwise agree on the amount involved. No claim for an adjustment in the Contract Price will be valid if not submitted in accordance with this paragraph 11.2. 11.3. The value of any Work covered by a Change Order or of any claim for an adjustment in the Contract Price will be determined by the following procedures: 11.3.1. Designated Unit Price (Field Measure). CONTRACTOR and OWNER recognize and acknowledge that the quantities shown for those items designated in the Bid Proposal as unit price items are approximations prepared by OWNER for bid purposes and that the actual compensation payable to CONTRACTOR for the utilization of such items is based upon the application of unit prices to the actual quantities of items involved as measured in the field and required to complete the Work as originally defined in the Contract Documents. 11.3.2. When it is determined by OWNER that an addition, deletion, or revision to the Work, as defined in these Contract Documents, is required and affects the quantities required for items designed in the Bid Proposal as unit price items, CONTRACTOR and OWNER agree that the compensation payable to CONTRACTOR for such unit price items shall be adjusted accordingly by a Change Order based upon the application of the appropriate unit prices shown in the Bid Proposal to the quantity of the unit price item required to complete the Work as defined in the Contract Documents. 11.3.3. Other Unit Prices. For items not designated in the bid proposal as unit prices, OWNER and CONTRACTOR may establish unit prices as agreed on by Change Order. 11.3.4. Lump Sum. When it is determined by OWNER that an addition, deletion or revision to the Work is required which results in a change in Work designated in the Bid Proposal as a lump sum item, the amount of increase or decrease in the lump sum price shall be established by mutual agreement of the parties. 11.3.5. If the pricing methods specified in 11.3 are inapplicable, or if the parties are unable to agree on a price for the changed work, a reasonable price for the same shall be established by OWNER in accordance with 11.4 and 11.5. OWNER shall then process a unilateral Change Order, specifying the said reasonable price, in accordance with 11.4 through 11.6. CONTRACTOR shall perform the Work as directed in the Change Order. 11.3.6. Failure on the part of CONTRACTOR to construct any item to plan or authorized dimensions within the specification tolerances shall result in: reconstruction to acceptable tolerances at no additional costs to OWNER; acceptance at no pay; or acceptance at reduced final pay quantity or reduced unit price, all at the GC -30 discretion of OWNER. Determinations of aggregate monetary change for items identified as lump sum quantities shall be made by OWNER based upon an analysis of the scope of CONTRACTOR's failure to construct to plan or authorized dimensions. Cost of the Work: 11.4. The term Cost of the Work means the sum of all costs necessarily incurred and paid by CONTRACTOR in the proper performance of the Work. Except as otherwise may be agreed to in writing by OWNER, such costs shall be in amounts no higher than those prevailing in the locality of the Project, shall include only the following items and shall not include any of the costs itemized in paragraph 11.5: 11.4.1. Payroll costs for employees in the direct employ of CONTRACTOR in the performance of the Work under schedules of job classifications agreed upon by OWNER and CONTRACTOR. Payroll costs for employees not employed full time on the Work shall be apportioned on the basis of their time spent on the Work. Payroll costs shall include, but not be limited to, salaries and wages plus the cost of fringe benefits which shall include social security contributions, unemployment, excise and payroll taxes, workers' or workmen's compensation, health and retirement benefits, bonuses, sick leave, vacation and holiday pay applicable thereto. Such employees shall include superintendents and foremen at the site. The expenses of performing Work after regular working hours, on Saturday, Sunday or legal holidays, shall be included in the above to the extent authorized by OWNER. 11.4.2. Cost of all materials and equipment furnished and incorporated in the Work, including costs of transportation and storage thereof, and Suppliers' field services required in connection therewith. All cash discounts shall accrue to CONTRACTOR unless OWNER deposits funds with CONTRACTOR with which to make payments, in which case the cash discounts shall accrue to OWNER. Trade discounts, rebates and refunds and all returns from sale of surplus materials and equipment shall accrue to OWNER, and CONTRACTOR shall make provisions so that they may be obtained. 11.4.3. Payments made by CONTRACTOR to the Subcontractors for Work performed by Subcontractors. If required by OWNER, CONTRACTOR shall obtain competitive bids from Subcontractors acceptable to CONTRACTOR and shall deliver such bids to OWNER who then determines, with the advice of PROFESSIONAL, which bids will be accepted. If a subcontract provides that the Subcontractor is to be paid on the basis of Cost of the Work Plus a Fee, the Subcontractor's Cost of the Work shall be determined in the same manner as CONTRACTOR's Cost of the Work. All subcontracts shall be subject to the other provisions of the Contract Documents insofar as applicable. 11.4.4. Costs of special consultants (including but not limited to engineers, architects, testing laboratories, surveyors, attorneys and accountants) employed for services specifically related to the Work. 11.4.5. Supplemental costs including the following: 11.4.5.1. The proportion of necessary transportation, travel and subsistence expenses of CONTRACTOR's employees incurred in discharge of duties connected with the Work. 11.4.5.2. Cost, including transportation and maintenance, of all materials, supplies, equipment, machinery, appliances, office and temporary facilities at the site and hand tools not owned by the workers, which are consumed in the performance of the Work, and cost less market value of such items used but not consumed which remain the property of CONTRACTOR. GC-31 11.4.5.3. Rentals of all construction equipment and machinery and the parts thereof whether rented from CONTRACTOR or others in accordance with rental agreements approved by OWNER with the advice of PROFESSIONAL, and the costs of transportation, loading, unloading, installation, dismantling and removal thereof - all in accordance with terms of said rental agreements. The rental of any such equipment, machinery or parts shall cease when the use thereof is no longer necessary for the Work. 11.4.5.4. Sales, consumer, use or similar taxes related to the Work, and for which CONTRACTOR is liable, imposed by Laws and Regulations. 11.4.5.5. Deposits lost for causes other than negligence of CONTRACTOR, any Subcontractor or anyone directly or indirectly employed by any of them or for whose acts any of them may be liable, and royalty payments and fees for permits and licenses. 11.4.5.6. Losses and damages (and related expenses), not compensated by insurance or otherwise, to the Work or otherwise sustained by CONTRACTOR in connection with the performance and furnishing of the Work (except losses and damages within the deductible amounts of property insurance established by OWNER in accordance with paragraph 5.6) provided they have resulted from causes other than the negligence of CONTRACTOR, any Subcontractor, or anyone directly or indirectly employed by any of them or for whose acts any of them may be liable. Such losses shall include settlements made with the written consent and approval of OWNER. No such losses, damages and expenses shall be included in the Cost of the Work for the purpose of determining CONTRACTOR's Fee. If, however, any such loss or damage requires reconstruction and CONTRACTOR is placed in charge thereof, CONTRACTOR shall be paid for services a fee proportionate to that stated in paragraph 11.6.2. 11.4.5.7. The cost of utilities, fuel and sanitary facilities at the site. 11.4.5.8. Minor expenses such as telegrams, long distance telephone calls, telephone service at the site, expressage and similar petty cash items in connection with the Work. 11.4.5.9. Cost of premiums for additional Bonds and insurance required because of changes in the Work and premiums of property insurance coverage within the limits of the deductible amounts established by OWNER in accordance with paragraph 5.6. 11.5. The term Cost of the Work shall not include any of the following: 11.5.1. Payroll costs and other compensation of CONTRACTOR's officers, executives, principals (of partnership and sole proprietorships), general managers, engineers, architects, estimators, attorneys, auditors, accountants, purchasing and contracting agents, expeditors, timekeepers, clerks and other personnel employed by CONTRACTOR whether at the site or in CONTRACTOR's principal or a branch office for general administration of the Work and not specifically included in the agreed upon schedule of job classifications referred to in paragraph 11.4.1 or specifically covered by paragraph 11.4.4-all of which are to be considered administrative costs covered by CONTRACTOR's Fee. 11.5.2. Expenses of CONTRACTOR's principal area branch offices other than CONTRACTOR's office at the site. 11.5.3. Any part of CONTRACTOR's capital expenses, including interest on CONTRACTOR'S capital used for the Change Order Work and charges against CONTRACTOR for delinquent payments. GC-32 11.5.4.

Other overhead or general expense costs of any kind and the costs of any item not specifically and expressly included in paragraph 11.4. CONTRACTOR's Fee: 11.6. CONTRACTOR's Fee allowed to CONTRACTOR for overhead and profit shall be determined as follows: 11.6.1. a mutually acceptable fixed fee, or if none can be agreed upon; 11.6.2. a fee based on the following percentages of the various portions of the Cost of the Work: 11.6.2.1. for costs incurred under paragraphs 11.4.1 and 11.4.2, CONTRACTOR's Fee shall be fifteen percent, 11.6.2.2. for costs incurred under paragraph 11.4.3, CONTRACTOR's Fee shall five percent; and if a subcontract is on the basis of Cost of the Work Plus a Fee, the maximum allowable to CONTRACTOR on account of overhead and profit of all Subcontractors shall be fifteen percent, 11.6.2.3. no fee shall be payable on the basis of costs itemized under paragraphs 11.4.4, 11.4.5 and 11.3, 11.6.2.4. the amount of credit to be allowed by CONTRACTOR to OWNER for any such change which results in a net decrease in cost will be the amount of the actual net decrease plus a deduction in CONTRACTOR's Fee by an amount equal to ten percent of the net decrease, and 11.6.2.5. when both additions and credits are involved in anyone change, the adjustment in CONTRACTOR's Fee shall be computed on the basis of the net change in accordance with paragraphs 11.6.2.1 through 11.6.2.4, inclusive. 11.7. For all changes, CONTRACTOR shall submit an itemized cost breakdown, together with supporting data in such detail and form as prescribed by the Project Manager. When a credit is due, the amount of credit to be allowed by CONTRACTOR to OWNER for any such change which results in a net decrease in cost will be the amount of the actual net decrease in direct cost as determined by the Project Manager, plus the applicable reduction in overhead and profit. When both additions and credits are involved in any change, the combined overhead and profit shall be calculated on the basis of the net change, whether an increase or decrease. In any event, the minimum detail shall be an itemization of all man-hours required by discipline/trade with the unit cost per man-hour and total labor price, labor burden, equipment hours and rate for each piece of equipment, material by units of measure and price per unit, other costs specifically itemized, plus the overhead and profit markup. GC -33 Cash Allowances: 11.8. It is understood that CONTRACTOR has included in the Contract Price all allowances so named in the Contract Documents and shall cause the Work so covered to be done by such Subcontractors or Suppliers and for such sums within the limit of the allowances as may be acceptable to PROFESSIONAL CONTRACTOR agrees that: 11.8.1. The allowances include the cost to CONTRACTOR (less any applicable trade discounts) of materials and equipment required by the allowances to be delivered at the site and all applicable taxes; and 11.8.2. CONTRACTOR's costs for unloading and handling on the site, labor, installation costs, overhead, profit and other expenses contemplated for the allowances have been included in the Contract Price and not in the allowances. No demand for additional payment on account of any thereof will be valid. Prior to final payment, an appropriate Change Order will be issued as recommended by PROFESSIONAL to reflect actual amounts due CONTRACTOR on account of Work covered by allowances, and the Contract Price shall be correspondingly adjusted. Unit Price Work: 11.9.1. Where the Contract Documents provide that all or part of the Work is to be Unit Price Work, initially the Contract Price will be deemed to include for all Unit Price Work an amount equal to the sum of the established unit prices for each separately identified item of Unit Price Work times the estimated quantity of each item as indicated in the Agreement. The estimated quantities of items of Unit Price Work are not guaranteed and are solely for the purpose of comparison of Bids and determining an initial Contract Price. Determinations of the actual quantities and classifications of Unit Price Work performed by CONTRACTOR will be made by PROFESSIONAL in accordance with Paragraph 9.10. 11.9.2. Each unit price will be deemed to include an amount considered by CONTRACTOR to be adequate to cover CONTRACTOR's overhead and profit for each separately identified item. 11.9.3. Where the quantity of any item of Unit Price Work performed by CONTRACTOR differs materially and significantly from the estimated quantity of such item indicated in the Agreement and there is no corresponding adjustment with respect to any other item of Work and if CONTRACTOR believes that CONTRACTOR has incurred additional expense as a result thereof, CONTRACTOR may make a claim for an increase in the Contract Price in accordance with Article 11 if the parties are unable to agree as to the amount of any such increase. GC-34 ARTICLE 12--CHANGE OF CONTRACT TIME 12.1. The Contract Time may only be changed by a Change Order. Any request for an extension in the Contract Time shall be made in writing and delivered to PROFESSIONAL and OWNER within seven (7) calendar days of the occurrence first happening and resulting in the claim. Written supporting data will be submitted to PROFESSIONAL and OWNER within fifteen (15) calendar days after such occurrence unless the OWNER allows additional time. All claims submitted by CONTRACTOR for adjustments to the Contract Time must set forth in detail the reasons for and causes of the delay and clearly indicate why the subject delay was beyond CONTRACTOR's control or fault. 12.2. If CONTRACTOR is delayed at any time in the performance, progress, commencement, or completion of the Work by any act or neglect of OWNER or PROFESSIONAL, or by an employee of either, or by any separate CONTRACTOR employed by OWNER, or by changes ordered in the Work, or by labor disputes, fire, unavoidable casualties, utility conflicts which could not have been identified or foreseen by CONTRACTOR using reasonable diligence, or any causes beyond CONTRACTOR's control or fault, then the Contract Time shall be extended by Change Order for such reasonable time as OWNER may determine. CONTRACTOR shall be entitled to an extension of time for such causes only for the number of days of delay which OWNER may determine to be due solely to such causes and only to the extent such occurrences actually delay the completion of the Work and then only if CONTRACTOR shall have strictly complied with all the requirements of the Contract Documents. Provided, however, notwithstanding anything in the Contract Documents to the contrary, no interruption, interference, inefficiency, suspension or delay in the performance, progress, commencement or completion of the Work for any cause whatsoever, including those for which OWNER or PROFESSIONAL may be responsible in whole or in part, shall relieve CONTRACTOR of its duty to perform or give rise to any right to damages or additional compensation from OWNER. CONTRACTOR's sole and exclusive remedy against OWNER for interruption, interference, inefficiency, suspension or delay of any aspect of the Work shall be the right to seek an extension to the Contract Time in accordance with the procedures set forth herein. GC-35 ARTICLE 13 - WARRANTY AND GUARANTEE; TESTS AND INSPECTIONS: CORRECTION, REMOVAL OR ACCEPTANCE OF DEFECTIVE WORK Warranty and Guarantee: 13.1. CONTRACTOR warrants and guarantees to OWNER that all materials and equipment will be new unless otherwise specified and that all work will be of good quality, performed in a workmanlike manner, free from faults or defects, and in accordance with the requirements of the Contract Documents and any inspections, tests, or approvals referred to in this Article. All unsatisfactory Work, all faulty Work and all Work not conforming to the requirements of the Contract Documents or such inspections, tests, approvals, or all applicable building, construction and safety requirements shall be considered defective. Notice of all defects shall be given to CONTRACTOR by PROFESSIONAL. All defective work, whether or not in place, may be rejected, corrected, or accepted as provided in this Article. Access to Work: 13.2. For the duration of the Work, PROFESSIONAL and its representatives, other designated representatives of OWNER, and authorized representatives of any regulatory agency shall at all times be given access to the Work. CONTRACTOR shall provide proper facilities for such access and observation of the Work and also for any inspection or testing by others. Tests and Inspections: 13.3. If the Contract Documents, laws, ordinances, rules, regulations or orders of any public authority having jurisdiction require any Work to specifically be inspected, tested, or approved by someone other than CONTRACTOR, CONTRACTOR shall give PROFESSIONAL timely notice of readiness therefore. 13.4. The testing firm(s) (if assigned by OWNER to this Work) and all such inspections, tests, or approvals provided for by OWNER shall be identified in writing by PROFESSIONAL to CONTRACTOR. All other inspections, tests or approvals shall be at CONTRACTOR's expense including additional expenses for inspection and tests required as a result of delays by CONTRACTOR or hours worked in excess of 40 hours per week. For all required inspections, tests, and approvals on any Work prepared, performed, or assembled away from the site, CONTRACTOR will furnish PROFESSIONAL with the required Certificates of Inspection, testing, or approval. All such tests will be in accordance with the methods prescribed by the American Society for Testing and Materials or such other applicable organizations as may be required by law or the Contract Documents. Materials or Work in place that fail to pass acceptability tests shall be retested at the direction of PROFESSIONAL and at CONTRACTOR's expense. 13.5. All inspections, tests or approvals other than those required by Laws or Regulations of any public body having jurisdiction shall be performed by organizations acceptable to OWNER and CONTRACTOR (or by PROFESSIONAL if so specified). 13.6. If any Work (including the work of others) that is to be inspected, tested or approved is covered without written concurrence of PROFESSIONAL, it must, if requested by PROFESSIONAL, be uncovered for observation. Such uncovering shall be at CONTRACTOR's expense unless CONTRACTOR has given PROFESSIONAL timely notice of CONTRACTOR's intention to cover the same and PROFESSIONAL has not acted with reasonable promptness in response to such notice. GC-36 13.7. Neither observations by PROFESSIONAL or Project Manager nor inspections, tests, or approvals by persons other than CONTRACTOR shall relieve CONTRACTOR of its obligations to perform the Work in accordance with the requirements of the Contract Documents. Uncovering Work: 13.8. If any Work required to be inspected, tested or approved is covered prior thereto without the prior written approval of PROFESSIONAL, or if any Work is covered contrary to the request of PROFESSIONAL, the Work shall, if requested by PROFESSIONAL, be uncovered for observation, inspection, testing or approval and replaced at CONTRACTOR's expense. 13.9. If PROFESSIONAL considers it necessary or advisable that covered Work be observed by PROFESSIONAL or inspected or tested by others, CONTRACTOR, at PROFESSIONAL's request, shall uncover, expose or otherwise make available for observation, inspection or testing as PROFESSIONAL may require, that portion of the Work in question, furnishing all necessary labor, material and equipment. If it is found that such Work is defective, CONTRACTOR shall bear all direct and consequential costs of such uncovering, exposure, observation, inspection and testing and of satisfactory reconstruction (including but not limited to fees and charges of PROFESSIONALs, architects, attorneys and other PROFESSIONALs), and OWNER shall be entitled to an appropriate decrease in the Contract Price and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefore as provided in Article 11. If, however, such Work is not found to be defective, CONTRACTOR shall be allowed an increase in the Contract Price or an extension of the Contract Time, or both, directly attributable to such uncovering, exposure, observation, inspection, testing and reconstruction, and, if the parties are unable to agree as to the amount or extent thereof, CONTRACTOR may make a claim therefore as provided in Articles 11 and 12. OWNER May Stop the Work: 13.10. When Work is defective or when CONTRACTOR fails to supply sufficient skilled workmen or suitable materials or equipment or make prompt payments to Subcontractors for labor, materials, or equipment or if CONTRACTOR violates any provisions of these Contract Documents, OWNER may order CONTRACTOR to stop the Work until the cause for such order has been eliminated. However, this right of OWNER to stop the Work shall not give rise to any duty on the part of OWNER to exercise this right for the benefit of CONTRACTOR or any other party. CONTRACTOR shall have no right to claim an increase in the Contract Price or Contract Time or other damages for a stop work order under this paragraph. Correction or Removal of Defective Work: 13.11. When directed by PROFESSIONAL, CONTRACTOR shall promptly, without cost to OWNER and as specified by PROFESSIONAL, either correct the defective Work whether fabricated, installed, or completed, or remove it from the site and replace it with non-defective Work. If CONTRACTOR does not correct such defective Work or remove and replace such defective Work within a reasonable time, as specified in a written notice from PROFESSIONAL, OWNER may have the deficiency corrected. All direct and indirect costs of such correction shall be paid by CONTRACTOR or deducted from payment to CONTRACTOR. CONTRACTOR will also bear the expense of correcting or removing and replacing all Work of others destroyed or damaged by the correction, removal, or replacement of the defective Work. GC-37 One Year Correction Period: 13.12. If, after approval of final payment and prior to the expiration of one year after the date of substantial completion or such longer period of time as may be prescribed by law or by the terms of any applicable special guarantee required by the Contract Documents, any Work or materials are found to be defective, incomplete, or otherwise not in accordance with the Contract Documents, CONTRACTOR shall promptly, without cost to OWNER and in accordance with OWNER's written instructions, either correct such defective Work or if it has been rejected by OWNER, remove it from the Site and replace it with non-defective Work. If CONTRACTOR does not promptly comply with the terms of such instructions, OWNER may have the defective Work corrected, removed, or replaced. All direct, indirect and consequential costs of such removal and replacement (including but not limited to fees and charges of engineers, architects, attorneys and other professionals) will be paid by CONTRACTOR. Acceptance of Defective Work: 13.13. If, instead of requiring correction or removal and replacement of defective Work, OWNER (and, prior to PROFESSIONAL's recommendation of final payment, PROFESSIONAL) prefers to accept it, OWNER may do so. CONTRACTOR shall bear all direct, indirect and consequential costs attributable to OWNER's evaluation of and determination to accept such defective Work (such costs to be approved by PROFESSIONAL as to reasonableness and to include but not be limited to fees and charges of engineers, architects, attorneys and other professionals). If any such acceptance occurs prior to PROFESSIONAL's recommendation of final payment, a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefore as provided in Article 11. If the acceptance occurs after such recommendation, an appropriate amount will be paid by CONTRACTOR to OWNER. OWNER May Correct Defective Work: 13.14. If CONTRACTOR fails within a reasonable time after written notice of PROFESSIONAL to proceed to correct defective Work or to remove and replace rejected Work as required by PROFESSIONAL in accordance with paragraph 13.11, or if CONTRACTOR fails to perform the Work in accordance with the Contract Documents, or if CONTRACTOR fails to comply with any other provision of the Contract Documents, OWNER may, after seven days' written notice to CONTRACTOR, correct and remedy any such deficiency. In exercising the rights and remedies under this paragraph, OWNER shall proceed expeditiously, to the extent necessary to complete corrective and remedial action. OWNER may exclude CONTRACTOR from all or part of the site, take possession of all or part of the Work, and suspend CONTRACTOR's services related thereto, take possession of CONTRACTOR's tools, appliances, construction equipment and machinery at the site and incorporate in the Work all materials and equipment stored at the site or for which OWNER has paid CONTRACTOR but which are stored elsewhere. CONTRACTOR shall allow OWNER, OWNER's representatives, agents and employees such access to the site as may be necessary to enable OWNER to exercise the rights and remedies under this paragraph. All direct, indirect and consequential costs of OWNER in exercising such rights and remedies will be charged against CONTRACTOR in an amount approved as to reasonableness by PROFESSIONAL, and a Change Order will be issued incorporating the necessary revisions in the Contract Documents with respect to the Work, and OWNER shall be entitled to an appropriate decrease in the Contract Price, and, if the parties are unable to agree as to the amount thereof, OWNER may make a claim therefore as provided in Article 11. Such direct, indirect and consequential costs will include, but not be GC-38 limited to, fees and charges of engineers, architects, attorneys and other professionals, all court costs and all costs of repair and replacement of work of others destroyed or damaged by correction, removal or replacement of CONTRACTOR's defective Work. CONTRACTOR shall not be allowed an extension of the Contract Time because of any delay in performance of the Work attributable to the exercise by OWNER of OWNER's rights and remedies hereunder. Neglected Work by CONTRACTOR 13.15. If CONTRACTOR neglects to execute the Work in accordance with the Contract Documents, including any requirements of the progress schedule, PROFESSIONAL may direct CONTRACTOR to submit a recovery plan and take specific corrective actions including, but not limited to, employing additional workmen and/ or equipment, and working extended hours and additional days, all at no cost to OWNER in order to put the Work back on schedule. If CONTRACTOR fails to correct the deficiency or take appropriate corrective action, OWNER may terminate the contract or CONTRACTOR's right to proceed with that portion of Work and have the Work done by others. The cost of completion under such procedure shall be charged against CONTRACTOR. A Change Order shall be issued incorporating the necessary revisions in the Contract Documents, including an appropriate reduction in the Contract Price. If the payments due CONTRACTOR are not sufficient to cover such amount, CONTRACTOR shall pay the difference to OWNER. 13.16. Should CONTRACTOR work overtime, weekends or holidays to regain the schedule, all costs to OWNER of associated inspection, construction management and resident engineers shall be identified to CONTRACTOR and the Contract Price reduced by a like amount via Change Order. GC -39 ARTICLE 14-PAYMENTS TO CONTRACTOR AND COMPLETION Schedule of Values: 14.1. The schedule of values established as provided in 2.9 will serve as the basis for progress payments and will be incorporated into a form of application for Payment acceptable to Project Manager. Progress payments on account of Unit Price Work will be based on the number of units completed. Application for Progress Payment: 14.2. At least twenty (20) calendar days before the date established for each progress payment (but not more often than once a month), CONTRACTOR shall submit to PROFESSIONAL for review an application for Payment filled out and signed by CONTRACTOR covering the work completed as of the date of the application and accompanied by such supporting documentation as is required by the Contract Documents. If payment is requested on the basis of materials and equipment not incorporated in the Work but delivered and suitably stored at the site or at another location agreed to in writing, the Application for Payment shall also be accompanied by a bill of sale, invoice or other documentation warranting that OWNER has received the materials and equipment free and clear of all liens and evidence that the materials and equipment are covered by appropriate property insurance and other arrangements to protect OWNER's interest therein, all of which will be satisfactory to OWNER. Payment is subject to a ten percent (10%) retainage that will be held until the final payment or acceptance by OWNER. The amount of retainage with respect to progress payments will be as stipulated in the Agreement. CONTRACTOR's Warranty of Title: 14.3. CONTRACTOR warrants and guarantees that title to all Work, materials and equipment covered by any Application for Payment, whether incorporated in the Project or not, will pass to OWNER no later than the time of payment free and clear of all Liens. Review of Applications for Progress Payment: 14.4. PROFESSIONAL will, within ten (10) calendar days after receipt of each Application for Payment, either indicate in writing a recommendation of payment and present the application to OWNER, or return the application to CONTRACTOR indicating in writing PROFESSIONAL's reasons for refusing to recommend payment. In the latter case, CONTRACTOR may make the necessary corrections and resubmit the application. OWNER shall, within thirty-one calendar days of presentation to him of the application for payment with PROFESSIONAL's recommendation of the amount for payment, pay CONTRACTOR amount recommended. 14.5. PROFESSIONAL's recommendation of any payment requested in an Application for Payment will constitute a representation by PROFESSIONAL to OWNER, based on PROFESSIONAL's on-site observations of the Work in progress as an experienced and qualified design PROFESSIONAL and on PROFESSIONAL's review of the Application for Payment and the accompanying data and schedules, that the Work has progressed to the point indicated; that, to the best of PROFESSIONAL's knowledge, information and belief, the quality of the Work is in accordance with the Contract Documents subject to an evaluation of the Work as a functioning whole prior to or upon Substantial Completion, to the results of any subsequent tests called for in the Contract Documents, to a final determination of quantities and classifications for Unit Price Work under GC-40 paragraph 9.10, and to any other qualifications stated in the recommendation; and that CONTRACTOR is entitled to payment of the amount recommended. However, by recommending any such payment, PROFESSIONAL will not thereby be deemed to have represented that exhaustive or continuous on-site inspections have been made to check the quality or the quantity of the Work beyond the responsibilities specifically assigned to PROFESSIONAL in the Contract Documents or that there may not be other matters or issues between the parties that might entitle CONTRACTOR to be paid additionally by OWNER or OWNER to withhold payment to CONTRACTOR. 14.6. PROFESSIONAL's recommendation of final payment will constitute an additional representation by PROFESSIONAL to OWNER that the conditions precedent to CONTRACTOR's being entitled to final payment as set forth in paragraph 14.13 have been fulfilled. 14.7. PROFESSIONAL may refuse to recommend the whole or any part of any payment if, in PROFESSIONAL's opinion, it would be incorrect to make such representations to OWNER. PROFESSIONAL may also refuse to recommend any such payment, or, because of subsequently discovered evidence or the results of subsequent inspections or tests, nullify any such payment previously recommended, to such extent as may be necessary in PROFESSIONAL's opinion to protect OWNER from loss because: 14.7.1. the Work is defective, or completed Work has been damaged requiring correction or replacement. 14.7.2. the Contract Price has been reduced by Written Amendment or Change Order. 14.7.3. OWNER has been required to correct defective Work or complete Work in accordance with paragraph 13.14. or 14.7.4. of PROFESSIONAL's actual knowledge of the occurrence of any of the events enumerated in paragraphs 15.2.1 through 15.2.9 inclusive. OWNER may refuse to make payment of the full amount recommended by PROFESSIONAL because claims have been made against OWNER on account of CONTRACTOR's performance or furnishing of the Work or Liens have been filed in connection with the Work or there are other items entitling OWNER to a off-set against the amount recommended, but OWNER must give CONTRACTOR immediate written notice (with a copy to PROFESSIONAL) stating the reasons for such action. Substantial Completion: 14.8. When CONTRACTOR considers the entire Work ready for its intended use, CONTRACTOR shall notify OWNER and PROFESSIONAL in writing that the entire Work is substantially complete (except for items specifically listed by CONTRACTOR as incomplete) and request that PROFESSIONAL issue a certificate of Substantial Completion. Within a reasonable time thereafter, OWNER, CONTRACTOR and PROFESSIONAL shall make an inspection of the Work to determine the status of completion. If PROFESSIONAL does not consider the Work substantially complete, PROFESSIONAL will notify CONTRACTOR in writing giving the reasons therefore. If PROFESSIONAL considers the Work substantially complete, PROFESSIONAL will prepare and deliver to OWNER a tentative certificate of Substantial Completion which shall fix the date of Substantial Completion. There shall be attached to the certificate a tentative list of items to be completed or corrected before final payment. OWNER shall have seven days after receipt of the tentative certificate during which to make written objection to PROFESSIONAL as to any provisions of the certificate or attached list. If, after considering such objections, PROFESSIONAL concludes that the Work is not substantially complete, GC-41 PROFESSIONAL will, within fourteen days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing stating the reasons therefore. If, after consideration of OWNER's, objections, PROFESSIONAL considers the Work substantially complete, PROFESSIONAL will within said fourteen days execute and deliver to OWNER and CONTRACTOR a definitive certificate of Substantial Completion (with a revised tentative list of items to be completed or corrected) reflecting such changes from the tentative certificate as PROFESSIONAL believes justified after consideration of any objections from OWNER. At the time of delivery of the tentative certificate of Substantial Completion, PROFESSIONAL will deliver to OWNER and CONTRACTOR a written recommendation as to division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, heat, utilities, insurance and warranties. Unless OWNER and CONTRACTOR agree otherwise in writing and so inform PROFESSIONAL prior to PROFESSIONAL's issuing the definitive certificate of Substantial Completion, PROFESSIONAL's aforesaid recommendation will be binding on OWNER and CONTRACTOR until final payment. 14.9. OWNER shall have the right to exclude CONTRACTOR from the Work after the date of Substantial Completion, but OWNER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization: 14.10. Use by OWNER at OWNER's option of any substantially completed part of the Work which (i) has specifically been identified in the Contract Documents, or (ii) OWNER, PROFESSIONAL, and CONTRACTOR agree constitutes a separately functioning and usable part of the Work that can be used by OWNER for its intended purpose without significant interference with CONTRACTOR's performance of the remainder of the Work, may be accomplished prior to Substantial Completion of all the Work subject to the following: 14.10.1. OWNER at any time may request CONTRACTOR in writing to permit OWNER to use any such part of the Work which OWNER believes to be ready for its intended use and substantially complete. If CONTRACTOR agrees, CONTRACTOR will certify to OWNER and PROFESSIONAL that said part of the Work is substantially complete and request PROFESSIONAL to issue a certificate of Substantial Completion for that part of the Work. CONTRACTOR at any time may notify OWNER and PROFESSIONAL in writing that CONTRACTOR considers any such part of the Work ready for its intended use and substantially complete and request PROFESSIONAL to issue a certificate of Substantial Completion for that part of the Work. Within a reasonable time after either such request, OWNER, CONTRACTOR and PROFESSIONAL shall make an inspection of that part of the Work to determine its status of completion. If PROFESSIONAL does not consider that part of the Work to be substantially complete, PROFESSIONAL will notify OWNER and CONTRACTOR, in writing, giving the reasons therefore. If PROFESSIONAL considers that part of the Work to be substantially complete, the provisions of paragraphs 14.8 and 14.9 will apply with respect to certification of Substantial Completion of that part of the Work and the division of responsibility in respect thereof and access thereto. 14.10.2. OWNER may at any time request CONTRACTOR, in writing, to permit OWNER to take over operation of any such part of the Work although it is not substantially complete. A copy of such request will be sent to PROFESSIONAL and, within a reasonable time thereafter, OWNER, CONTRACTOR and PROFESSIONAL shall make an inspection of that part of the Work to determine its status of completion, and PROFESSIONAL will prepare a list of the items remaining to be completed or corrected thereon before final payment. If CONTRACTOR does not object in writing to OWNER and PROFESSIONAL that such part of the GC-42 Work is not ready for separate operation by OWNER, PROFESSIONAL will finalize the list of items to be completed or corrected and will deliver such list to OWNER and CONTRACTOR together with a written recommendation as to the division of responsibilities pending final payment between OWNER and CONTRACTOR with respect to security, operation, safety, maintenance, utilities, insurance, warranties and guarantees for that part of the Work which will become binding upon OWNER and CONTRACTOR at the time when OWNER takes over such operation (unless they shall have otherwise agreed in writing and so informed PROFESSIONAL). During such operation and prior to Substantial Completion of such part of the Work, OWNER shall allow CONTRACTOR reasonable access to complete or correct items on said list and to complete other related Work. 14.10.3. No occupancy or separate operation of part of the Work will be accomplished prior to compliance with the requirements of paragraph 5.15 in respect of property insurance. 14.10.4. OWNER, may at its discretion, reduce the amount of retainage subject to Beneficial Occupancy. Final Inspection: 14.11. Upon written notice from CONTRACTOR that the entire Work or an agreed upon portion thereof is complete, PROFESSIONAL will make a final inspection with OWNER and CONTRACTOR and will notify CONTRACTOR in writing of all particulars in which this inspection reveals that the Work is incomplete or defective. CONTRACTOR shall immediately take such measures as are necessary to remedy such deficiencies. Final Application for Payment: 14.12. After CONTRACTOR has completed all such corrections to the satisfaction of PROFESSIONAL and OWNER and delivered in accordance with the Contract Documents all maintenance and operating instructions, schedules, guarantees, bonds, certificates or other evidence of insurance required by 5.2, certificates of inspection, marked-up record documents and other documents, CONTRACTOR may make application for final payment following the procedure for progress payments. The final Application for Payment shall be accompanied (except as previously delivered) by: (i) all documentation called for in the Contract Documents, including but not limited to the evidence of insurance required, (H) consent of the surety, if any, to final payment, and (Hi) complete and legally effective releases or waivers (satisfactory to OWNER) of all liens arising out of or filed in connection with the Work. In lieu of such releases or waivers of liens and as approved by OWNER, CONTRACTOR may furnish receipts or release in full and an affidavit of CONTRACTOR that (i) the releases and receipts include all labor, services, material and equipment for which a lien could be filed, and (ii) all payrolls, material and equipment bills and other indebtedness connected with the Work for which OWNER or OWNER's property might in any way be responsible have been paid or otherwise satisfied. If any Subcontractor or supplier fails to furnish such a release or receipt in full, CONTRACTOR may furnish a bond or other collateral satisfactory to OWNER to indemnify OWNER against any lien. 14.12.1. No application for final payment will be accepted by OWNER until approved as-built documents by CONTRACTOR are accepted and approved by PROFESSIONAL. 14.12.2. Notwithstanding any other provision of these contract documents to the contrary, OWNER and PROFESSIONAL are under no duty or obligation whatsoever to any vendor, materials provider, GC -43 Subcontractor, laborer or other party to ensure that payments due and owing by CONTRACTOR to any of them are or will be made. Such parties shall rely only on CONTRACTOR's surety bonds for remedy of nonpayment by him. CONTRACTOR agrees to defend and resolve all claims made by Subcontractors, indemnifying OWNER and PROFESSIONAL for all claims arising from or resulting from Subcontractor or supplier or material men or laborer services in connection with this project. 14.12.3. General Indemnity: CONTRACTOR shall indemnify OWNER and PROFESSIONAL for any damages sustained, including lost profits, resulting from CONTRACTOR's failure or refusal to perform the work required by these contract documents. Final Payment and Acceptance: 14.13. If, on the basis of PROFESSIONAL's observation of the Work during construction and final inspection and PROFESSIONAL's review of the final Application for Payment and accompanying documentation as required by the Contract Documents, PROFESSIONAL is satisfied that the Work has been completed and CONTRACTOR's other obligations under the Contract Documents have been fulfilled, PROFESSIONAL will, within ten (10) working days after receipt of the final Application for Payment, indicate in writing PROFESSIONAL's recommendation of payment and present the Application to OWNER for payment. At the same time PROFESSIONAL will also give written notice to OWNER and CONTRACTOR that the Work is acceptable subject to the provisions of 14.6. Otherwise, PROFESSIONAL will return the application to CONTRACTOR, indicating in writing the reasons for refusing to recommend final payment, in which case CONTRACTOR shall make the necessary corrections and resubmit the Application. After the presentation to OWNER of the application and accompanying documentation, in appropriate form and substance and with PROFESSIONAL's recommendation and notice of acceptability, the amount recommended by PROFESSIONAL will become due and will be paid by OWNER to CONTRACTOR. 14.14. If, through no fault of CONTRACTOR, final completion of the Work is significantly delayed and if PROFESSIONAL so confirms, OWNER shall, upon receipt of CONTRACTOR's final Application for Payment and recommendation of PROFESSIONAL and without terminating the Agreement, make payment of the balance due for that portion of the Work fully completed and accepted. If the remaining balance to be held by OWNER for Work not fully completed or corrected is less than the retainage stipulated in the Contract and if bonds have been furnished as required in Article 5, the written consent of the surety to the payment of the balance due for that portion of the Work fully completed and accepted shall be submitted by CONTRACTOR to PROFESSIONAL with the application for such payment. Such payment shall be made under the terms and conditions governing final payment, except that it shall not constitute a waiver of claims. CONTRACTOR's Continuing Obligation: 14.15. CONTRACTOR's obligation to perform and complete the Work in accordance with the Contract Documents shall be absolute.
