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.

If, instead of requiring correction or removal and replacement of defective Work, OWNER (and, prior to PROFESSIONAL's recommendation of final payment, also 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 PROFE~SIONAL as to reasonableness and to include but not be limited to fees and charges of PROFESSIONALs, 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 panics are unable to agree as to the amount thereof.

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 PROFES,SIONALs shall be identified to CONTRACTOR and the Contract Price reduced by a like amount via Change Order. GENERAL CONDITIONS 01001-43 ARTICLE 14-PA YMENTS 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.

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 support:ng 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.

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, GENERAL CONDITIONS 01001-44 I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I 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 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 per- formance or furnishing of the Work or Liens have been filed in connection with the Work or there are other items entitling OWNER to a set-off against the amount recommended, but GENERAL CONDITIONS 01001-45 OWNER must give CONTRACTOR immediate written notice (with a copy to PROFESSIONAL) stating the reasons for such action. Substantial Completion: I 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, CON~RACTOR 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 therefor. 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, PROFESSIONAL will within fourteen days after submission of the tentative certificate to OWNER notify CONTRACTOR in writing. stating the reasons therefor. 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 PROF- ESSIONAL 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 wilting 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 OWN ER shall allow CONTRACTOR reasonable access to complete or correct items on the tentative list. Partial Utilization: 14.10.

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 masons therefor.

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 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 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).

Weight of hydrostatic test fluid or cleaning fluid if normal operating fluid contents are lighter. 3. Reaction forces due to the operation of safety or relief valves. 4. Wind, snow or ice loadings on outdoor piping. Hangers and supports shall be sized to fit the outside diameter of pipe, tubing, or, where specified, the outside diameter of insulation. Where negligible movement occurs at hanger locations, rod hangers should be used for suspended lines, wherever practical. For piping supported from below, bases, brackets or structural cross members should be used. Hangers for the suspension of size 2-1/2 inches and larger pipe and tubing shall be capable of vertical hanger component adjustment under load. The supporting systems shall provide for and control the free or intended movement of the piping including its movement in relation to that of connected equipment. Where there is horizontal movement at a suspended type hanger location, hanger components shall be selected to allow for swing. The vertical angle of the hanger rod snelll not, at any time, exceed 4 degrees. There shall be no contact between a pipe and hanger or support component of dissimilar metals. Prevent contact between dissimilar metals when supporting copper tubing by use of copper-plated, rubber, plastic or vinyl coated, or stainless steel hanger and support components. Unless otherwise specified, existing pipes and supports shall not be used to support new piping. Unless otherwise specified, pipe support components shall not be attached to pressure vessels.
