APPLICATION FOR PAYMENT
INSTRUCTIONS
A. GENERAL INFORMATION
The sample form of Schedule of Values is intended as a guide only. Many projects require a more
extensive form with space for numerous items, descriptions of Change Orders, identification of variable
quantity adjustments, summary of materials and equipment stored at the site and other information. It is
expected that a separate form will be developed by Engineer and Contractor at the time Contractor's
Schedule of Values is finalized. Note also that the format for retainage must be changed if the Contract
permits (or the law provides), and Contractor elects to deposit securities in lieu of retain age. Refer to
Article 14 of the General Conditions for provisions conceming payments to Contractor.
B. COMPLETING THE FORM
The Schedule of Values, submitted and approved as provided in paragraphs 2.05.8.3 and 2.07 of the
General Conditions, should be reproduced as appropriate in the space indicated on the Application for
Payment form. Note that the cost of materials and equipment is often listed separately from the cost of
installation. Also, note that each Unit Price is deemed to include Contractor's overhead and profit.
All Change Orders affecting the Contract Price should be identified and included in the Schedule of
Values as required for progress payments.
The form is suitable for use in the Final Application for Payment as well as for Progress Payments;
however, the required accompanying documentation is usually more extensive for final payment. All
accompanying documentation should be identified in the space provided on the form.
C. LEGAL REVIEW
All accompanying documentation of a legal nature, such as Lien waivers, should be reviewed by an
attomey, and Engineer should so advise Owner.

CHANGE ORDER
INSTRUCTIONS
A. GENERAL INFORMATION
I
This document was developed to provide a uniform format for handling contract changes that affect Funds
Available or Contract Times. Changes that have been initiated by a Work Change Directive must be incorporated
into a subsequent Change Order if they affect Price or Times.
I
I
Changes that affect Funds Available or Contract Times should be promptly covered by a Change Order. The
practice of accumulating Change Orders to reduce the administrative burden may lead to unnecessary disputes.
If Milestones have been listed in the Agreement, any effect of a Change Order thereon should be addressed.
I
For supplemental instructions and minor changes not involving a change in the Contract Price or Contract Times,
a Field Order should be used.
B. COMPLETING THE CHANGE ORDER FORM
I
Engineer normally initiates the form, including a description of the changes involved and attachments based upon
documents and proposals submitted by Contractor, or requests from Owner, or both.
I
I
Once Engineer has completed and signed the form, all copies should be sent to Owner or Contractor for approval,
depending on whether the Change Order is a true order to the Contractor or the formalization of a negotiated
agreement for a previously performed change. After approval by one contracting party, all copies should be sent
to the other party for approval. Engineer should make distribution of executed copies after approval by both
parties.
I
If a change only applies to price or to times, cross out the part of the tabulation that does not apply.

I
The Augusta Utilities Department ("Owner") hereby requests proposals for a "Find and Fix" Sanitary
Sewer System Rehabilitation Project for the Spirit Creek Sanitary Sewer Interceptor. The Owner
seeks to enter into a contract with a Firm to provide the requested services outlined herein.
This contract is intended to be an inspection/repair/rehabilitation project with the emphasis placed on
documenting and correcting defects found within sanitary sewer lines and manholes that are
contributing inflow and infiltration to the system. The successful Firm will conduct the inspections,
perform necessary repairs to complete the inspections and complete rehabilitation/repairs to the sewer
system to eliminate defects identified from the inspections. Owner personnel will review
recommendations, approve corrective actions prior to implementation, provide project oversight and
inspect the quality and progress of the work.
The work consists of furnishing all labor, materials, equipment, other incidental items, and technical
competency necessary for performing all operations required to professionally execute the contract.
The work may include, but is not limited to, performing manhole inspections, sewer line cleaning and
internal Closed Circuit Television (CCTV) pipeline inspections, point repairs, sewer main
replacement, manhole rehabilitation, and Cured-In-PI ace-Pipe (CIPP) sewer rehabilitation. All work
shall be completed on or before July 30, 2002.
This contract will consist of indi vidual task orders issued by the Owner to the successful Firm.
Separate task orders will be developed for the "Find" and the ''Fix'' portion of the contract. Quantities
listed in the Unit Pay Item Schedule are estimates. These quantities may be exceeded or may not be
used; the use of these Pay Items shall be approved by the Owner. The current funding available for
this project is $600,000.

MlNORITY AND ECONOl\1ICALL Y DISADVANTAGED BUSINESS SUPPORT
It is the intent of the Augusta-Richmond County Commission to increase the involvement of qualified

items being considered equal, the contract, if awarded will be awarded to a minority and
economically disadvantaged Finn or a Finn that has included such Firms as subcontractors on this
project. The proposals shall include a statement of qualification for themselves and/or any qualified
subcontractors explaining why they should be considered a minority or economically disadvantaged
Firm. If the Finn does not fall into this category, no information is necessary.
ADDENDA AND INERPRETA TIONS
No interpretation of the meaning of plans, specifications or other pre-bid documents will be made to
any Finn orally. Every request for such interpretation should be given in writing addressed to the City
of Augusta Purchasing Department, and to be given consideration must be received at least ten days

supplemental instructions will be in the form of written addenda to the specifications which, if issued,
will be sent by certified mail with return receipt requested to all prospective Finns (at the respective
addresses furnished for such purposes), not later than five days prior to the date fixed for the
submittal of proposals. Failure of any Firm to receive any such addendum or interpretation shall not
relieve such Firm from any obligation under proposal as submitted. All addenda so issued shall
become part of the Contract Documents.

in the Contract lime shall be made in writing and delivered to PROFESSIONAL and Project Manager within
seven (7) calendar days of the occurrence first happening and resulting in the claim. Written supporting data
will be submitted to PROFESSIONAL and Project Manager within fifteen (15) calendar days after such
occurrence unless the Project Manager allows additional time. All claims submitted by CONTRACTOR for
adjustments to the Contract lime 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 lime 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 CONTRACTO-R 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, ineffidency, 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 lime in accordance with the
procedures set forth herein.

One Year Correction Period:
13.12. If, after approval of final payment and prior to the expiration of one year after the date of

(and, prior to PROFESSIONAL's recommendation of final payment, also PROFESSIONAL) prefers to accept

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
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

Contract Documents, OWNER may, after seven days' written notice to CONTRAcrOR, correct and remedy
any such deficiency. In exercising the rights and remedies under this paragraph OWNER shall proceed

CONTRAcrOR from all or part of the site, take possession of all or part of the Work, and suspend CON-
TRAcrOR's services related thereto, take possession of CONTRAcrOR'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 CONTRAcrOR but which are stored elsewhere. CONTRAcrOR 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 con-
sequential costs of OWNER in exercising such rights and remedies will be charged against CONTRAcrOR 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

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, induding 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 PROFESSIONAls shall be
identified to CONTRACTOR and the Contract Price reduced by a like amount via Change Order.

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

Documents. If payment is requested on the basis of materials and equipmef'it 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 Uens.
Review of Applications for Progress Payment:

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

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 PROF-
ESSIONAL'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 asset 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
Uens have been filed in connection with the Work or there are other items entitling OWNER to a set-off
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 con-
sider 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

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 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 wilting and so inform PROFESSIONAL
prior to PROFESSIONAL's issuing the definitive certificate of Substantial Completion, PROFESSIONAL's afore-
said 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. 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 inspec-
tion 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 therefor. If PROFESSIONAL considers that part o(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
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). 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.

Contract Documents, including but not limited to the evidence of insurance required, (ii) 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

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

and PROFESSIONAL are under no duty or obligation whatsoever to any vendor, materials provider,
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

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.

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. Neither recommendation of any progress or final payment by PROFESSIONAL,

APPLICATION FOR PAYMENT
INSTRUCTIONS
A. GENERAL INFORMATION
The sample form of Schedule of Values is intended as a guide only. Many projects require a more
extensive form with space for numerous items, descriptions of Change Orders, identification of variable
quantity adjustments, summary of materials and equipment stored at the site and other information. It is
expected that a separate form will be developed by Engineer and Contractor at the time Contractor's
Schedule of Values is finalized. Note also that the format for retainage must be changed if the Contract
permits (or the law provides), and Contractor elects to deposit securities in lieu of retainage. Refer to
Article 14 of the General Conditions for provisions concerning payments to Contractor.
B. COMPLETING THE FORM
The Schedule of Values, submitted and approved as provided in paragraphs 2.05.B.3 and 2.07 of the
General Conditions, should be reproduced as appropriate in the space indicated on the Application for
Payment form. Note that the cost of materials and equipment is often listed-separately from the cost of
installation. Also, note that each Unit Price is deemed to include Contractor's overhead and profit.
All Change Orders affecting the Contract Price should be identified and included in the Schedule of
Values as required for progress payments.
The form is suitable for use in the Final Application for Payment as well as for Progress Payments;
however, the required accompanying documentation is usually more extensive for final payment. All
accompanying documentation should be identified in the space provided on the form.
C. LEGAL REVIEW
All accompanying documentation of a legal nature, such as Lien waivers, should be reviewed by an
attorney, and Engineer should so advise Owner.

CHANGE ORDER
INSTRUCTIONS
A. GENERAL INFORMATION
This document was developed to provide a uniform format for handling contract changes that affect Contract
Price or Contract Times. Changes that have been initiated by a Work Change Directive must be incorporated into
a subsequent Change Order if they affect Price or Times.
Changes that affect Contract Price or Contract Times should be promptly covered by a Change Order. The
practice of accumulating Change Orders to reduce the administrative burden may lead to unnecessary disputes.
If Milestones have been listed in the Agreement, any effect of a Change Order thereon should be addressed.
For supplemental instructions and minor changes not involving a change in the Contract Price or Contract Times,
a Field Order should be used.
B. COMPLETING THE CHANGE ORDER FORM
Engineer normally initiates the form, including a description of the changes involved and. attachments based upon
documents and proposals submitted by Contractor, or requests from Owner, or both.
Once Engineer has completed and signed the form, all copies should be sent to Owner or Contractor for approval,
depending on whether the Change Order is a true order to the Contractor or the formalization of a negotiated
agreement for a previously performed change. After approval by one contracting party, all copies should be sent
to the other party for approval. Engineer should make distribution of executed copies after approval by both
parties.
If a change only applies to price or to times, cross out the part of the tabulation that does not apply.

Erosion and Sediment Control
PART 3
EXECUTION
3.01 GENERAL
A. Standards: Provide all materials and promptly take all actions necessary to achieve
effective erosion and sedimentation control in accordance with the Georgia Erosion
and Sedimentation Act of 1975 as amended in 1989, local enforcing agency
guidelines and these Specifications.
3.02 TEl\1PORARY EROSION AND SEDIl\1ENTATION CONTROL
A. Temporary erosion and sedimentation control procedures should be initially directed
toward preventing silt and sediment from entering the creeks. The preferred method
is to provide an undisturbed natural buffer, extending a minimal 25 feet from the top
of the bank, to fIlter the runoff. Should this buffer prove infeasible due to
construction activities being too close to the creek, or if the amount of sediment
overwhelms the buffer, the Contractor shall place silt fences to fIlter the runoff and,
if necessary, place permanent Rip Rap to stabilize the creek banks. When
excavation activities disturb the previously stated preventative measures or if they
are not maintained, or whenever the construction activities cross the creeks, the
check dams shall be installed downstream and within 200 feet of the affected area.
B. Silt dams, silt fences, traps, barriers, check dams, appurtenances and other
temporary measures and devices shall be installed as approved and shall be
maintained until no longer needed, and shall then be removed. Deteriorated hay
bales and dislodged fIlter stone shall be replaced with new materials. Detention
ponds, if constructed, shall be maintained in a condition ensuring that unfiltered
water will not leave the pond.
C. Where permanent grassing is not appropriate, and where the Contractor's temporary
erosion and sedimentation control practices are inadequate, the Engineer may direct
the Contractor to provide temporary vegetative cover with fast growing seedlings.
Such temporary vegetative cover shall be provided by the Contractor in compliance
with the Manual for Erosion and Sedimentation Control in Georgia, specifically in
the selection of species, planting dates and application rates for seedlings, fertilizer
and mulching, with the exception that kudzu shall not be permitted.
D. All erosion and sedimentation control devices, including check dams, shall be
inspected by the Contractor at least weekly and after each rainfall occurrence and
cleaned out and repaired by the Contractor as necessary.
E. Temporary erosion and sedimentation control devices shall be installed and
maintained from the initial land disturbance activity until the satisfactory completion

and establishment of permanent erosion control measures. At that time, temporary
devices shall be removed.
3.03 PERMANENT EROSION CONTROL
A. Permanent Erosion Control Shall Include:
1. Restoring the work site to its original contours, unless otherwise directed
by the Engineer.
2. Permanent vegetative cover shall be performed in accordance with Item 3.04
of this section.
3. Permanent stabilization of steep slopes and creeks shall be performed in
accordance with Item 3.05 of this section.
B. Permanent erosion control measures shall be implemented as soon as practical after
the completion of pipe installation or land disturbance for each segment of the
Project. In no event shall implementation be postponed when no further
construction activities will impact that portion or segment of the Project. Partial
payment requests may be withheld for those portions of the Project not complying
with this requirement.
3.04 GRASSING
A. General:
1. All references to grassing, unless noted otherwise, shall relate to establishing
permanent vegetative cover as specified herein for seeding, fertilizing,
mulching, etc.
2. When final grade has been established, all bare soil, unless otherwise
required by the Contract Documents, shall be seeded, fertilized and mulched
in an effort to restore to a protected condition. Critical areas shall be sodded
as approved or directed by the Engineer.
3. Specified permanent grassing shall be performed at the first appropriate
season following establishment of final grading in each section of the site.
4. Permanent grassing shall be of a perennial species.
B. Replant grass removed or damaged in residential areas using the same variety of
grass and at the first appropriate season. Where sod is removed or damaged, replant
such areas using sod of the same species of grass at the first appropriate season.
Outside of residential or landscaped areas, grass the entire area disturbed by the

C.
Grassing activities shall comply with the Manual for Erosion and Sediment Control
in Georgia, specifically for the selection of species, with the exception that kudzu
shall not be permitted, planting dates and application rates for seeding, fertilizer and
mulching. Where permanent vegetative cover (grassing) cannot be immediately

3.05 PLACING OF RIP RAP
A. Rip rap shall be placed where ordered by the Engineer, at all points where banks of
streams or drainage ditches are disturbed by excavation, or at all points where
natural vegetation is removed from banks of the streams or drainage ditches.
Carefully compact backfill and place rip rap to prevent subsequent settlement and
erosion. This requirement applies equally to construction along side a stream or
drainage ditches as well as crossing a stream or drainage ditch.
B. When trenching across a creek, place Rip Rap a distance of 10 feet upstream and
10 feet downstream from the top of the trench excavation. Place Rip Rap across
creek bottom, across creek banks and extend Rip Rap placement 5 feet beyond the
top of each creek bank.
C. Preparation of Fou.ndations: The ground surface upon which the rip rap is to be
placed shall be brought in reasonably close conformity to the correct lines and
grades before placement is commenced. Where fIlling of depressions is required,
the new material shall be compacted with hand or mechanical tampers. Unless at
creek banks or otherwise shown or specified, Rip Rap shall begin in a toe ditch
constructed in original ground around the toe of the fill or the cut slope. The toe
ditch shall be 2 feet deep in original ground and the side next to the fill or cut shall
have that same slope. After the Rip Rap is placed, the toe ditch shall be backfilled
and the excess dirt spread neatly within the construction easement.

include the removal of all materials of whatever nature encountered, including all
obstructions of any nature that would interfere with the proper execution and
completion of the work. The removal of said materials shall conform to the lines
and grades indicated or ordered. Unless otherwise indicated, the entire construction
site shall be stripped of all vegetation and debris, and such material shall be
removed from the site prior to performing any excavation or placing any fill. The
Contractor shall furnish, place, and maintain all supports and shoring that may be
required for the sides of the excavations. Excavations shall be sloped or otherwise
supported in a safe manner in accordance with applicable State safety requirements
and the requirements of OSHA Safety and Health -Standards for Construction
(29CFR1926).
B. Removal and Exclusion of Water: The Contractor shall remove and exclude water,
including stormwater, groundwater, irrigation water, and wastewater, from all
excavations. Dewatering wells, wellpoints, sump pumps, or other means shall be
used to remove water and continuously maintain groundwater at a level at least
2 feet below the bottom of excavations before the excavation work begins at each
location. Water shall be removed and excluded until backfilling is complete and all
field soils testing have been completed.
3.02 STRUCTURE, ROADWAY, AND EMBANKMENT EXCAVATION
A. Excavation Beneath Structures and Embankments: Except where otherwise
indicated for a particular structure or ordered by the Engineer, excavation shall be
carried to the grade of the bottom of the footing or slab. Where indicated or
ordered, areas beneath structures or fills shall be over-excavated. The subgrade
areas beneath embankments shall be excavated, removing no less than the top
6 inches of native material. If such sub grade is sloped, the native material shall be
benched. When such over-excavation is indicated both over-excavation and
subsequent backfIll to the required grade shall be performed by the Contractor.
When sucb"over-excavation is not indicated, but is ordered by the Engineer, such
over-excavation and any resulting backfill will be paid for under a separate unit
price bid item, if such bid item has been established. Otherwise, payment will be
made in accordance with a negotiated price. After the required excavation or
over-excavation has been completed, the exposed surface shall be scarified to a
depth of 6 inches, brought to optimum moisture content, and rolled with heavy
compaction equipment to obtain 95% of maximum density.
B. Excavation Beneath Paved Areas: Excavation under areas to be paved shall extend
to the bottom of the aggregate base or subbase, if such base is called for; otherwise,

SECTION 02511
Preconditioning and Cleaning Manholes And Sewers
PART 1- GENERAL
1.01 SCOPE
A. The objective of preconditioning and cleaning is to maximize sewer and manhole
service efficiency and effectiveness. Preconditioning and cleaning involves
removal of silt defined as any and all solid or semi-solid materials, including fine
and granular material, such as sand, grit, gravel, and rock as well as debris,
grease, oil, sludge, slime, or any other loose material or encrustation lodged in the
manhole or sewer. Preconditioning and cleaning also involves removal of
invading roots, corroded concrete, corroded manhote rungs, corroded ladders,
intruding laterals and any other extraneous debris.
Two levels of performance concerning preconditioning and cleaning of manholes
and sewers shall be adhered to in this contract, as directed:
1. Preconditioning and cleaning as a general level of service; this requires
that manholes and sewers shall be considered preconditioned and cleaned
if:
a. Silt is removed and disposed of to not more than a nominal depth
of 10% of the through flow channel in manholes, or sewer between
manholes, where the through flow channel or sewer has an
equivalent diameter up to and including 24 inches, and
b. Silt is removed and disposed of to not more than a nominal depth
of 5% of the through flow channel in manholes or sewer between
manholes, where the through flow channel or sewer has an
equivalent diameter greater than 24 inches.
c. No surface or appurtenance in manholes including walls, cones,
slabs (both intermediate and roof slabs), rungs and benches and
drop shafts shall have any remnant of silt, coating, loose bricks,
unsound concrete or mortar or loose material.
d. All roots, corroded concrete, corroded rungs, corroded ladders and
intruding laterals are treated or reduced and cut flush with the
interior surface of manholes and sewers, removed and disposed of.
Fulfillment of these requirements (e.g., depth of silt or cleanliness of
surface) is to be determined by internal manhole and sewer condition

Preconditioning and Cleaning Manholes and Sewers
surveyor inspection of each manhole and sewer length preconditioned or
cleaned as directed.
2. Preconditioning and cleaning prior to rehabilitation and repair; which
requires that manholes and sewers shall be considered preconditioned and
cleaned if, in addition to the requirements of 1.01.A.l above, all silt has
been removed from a minimum of 95% of the through flow channel and
sewer cross section. In the case of manholes, all surfaces shall be free of
cleaning agents and their reactant products. Fulfillment of these
requirements is to be established by internal manhole and sewer condition
surveyor inspection of each manhole and sewer length preconditioned or
cleansed as directed.
B. The Contractor shall precondition and clean the manholes and sewers listed
and/or shown on the Contract Drawings or specified herein so as to remove all
silt, debris, roots, corroded concrete, corroded rungs and ladders, intruding
laterals etc and dispose of the material at an approved site.
C. The manholes and lengths of sewers listed in the Bid Form provide the Contractor
with a basis for estimating the lengths and quantities of silt to be removed and
preconditioning to be performed. The Contractor must estimate quantities and
types of silt to be removed and the extent of preconditioning work required from
his own field reconnaissance of the manholes and sewers as well as inspection
and evaluation of any available relevant City record information. Interpretation of
any field observations and review of City records is the responsibility of the
Contractor.
D. During preconditioning and cleaning work, and all other associated Contractor
operations, sewer services shall be maintained at all times. This requirement may
be relaxed only with the written approval of the Engineer.
E. The manholes and sewers to be preconditioned and cleaned convey sanitary
sewage or combined sewage. In many instances, such sewers are subject to high
flows, either continuously or in a periodically varying cycle, due .to rainfall,
infIltration, and/or pumping operations. The Contractor shall include in his bid
provisions for dealing with such variations, and where necessary, schedule his
work to accommodate such variation in flows.
F. The Contractor shall submit a comprehensive equipment list to the Engineer
before commencement of the work. . The complete list, which shall include all
backup and standby equipment, shall be broken down into. the following
categories (at a minimum):
1. Safety equipment.
2. Manhole preconditioning and cleaning equipment.

Exfiltration Tests:
1. Low-Pressure Air Test: Sewer diameters less than or equal to 24 inches.
a. Prior to air testing, the section of sewer between manholes shall be
thoroughly cleaned and wetted. Immediately after cleaning or while
the pipe is water soaked, the sewer shall be tested with low-pressure
air. At the Contractor's option, sewers may be tested in lengths
between manholes or in short sections (25 feet or less) using
inflatable balls pulled through the line from manhole to manhole.
Air shall be slowly supplied to the plugged sewer section until
internal air pressure reaches approximately 4.0 psi. After this
pressure is reached and the pressure allowed to stabilize
(approximately 2 to 5 minutes), the pressure may be reduced to
3.5 psi before starting the test. If a 1.0-psi drop does not occur within
. the test time, then the line has passed the test. If the pressure drops
more than 1.0 psi during the test time, the line is presumed to have
failed the test, and the Contractor will be required to locate the
failure, make necessary repairs, and retest the line. Minimum test
time for various pipe sizes and types is as follows:

1. Contractor is responsible for locating any existing utilities in the area the
Contractor selects to locate the bypass pipelines. The Contractor shall
locate his bypass pipelines to minimize any' disturbances to existing
utilities and shall obtain approval of the pipeline locations from the City
and the Engineer. All costs associated with relocating utilities and
obtaining all approvals shall be paid by the Contractor.
2. During all bypass-pumping operations, the Contractor shall main,
manholes, and all local sewer lines from damage inflicted by any
equipment. The Contractor shall be responsible for all physical damage to
mains, manholes, and all local sewer lines caused by human or mechanical
failure.
3.03 PLUGGING OR BLOCKING
A. Insert sewer line plug into the line at a manhole upstream from the manhole or'
sewer that is to be rehabilitated and tested. For manhole rehabilitation, the plug
shall be designed so that a portion of the sewage can be released downstream.
During this portion of the operation, shut off or substantially reduce flows so that
the manhole can be properly cleaned, prepared and rehabilitated. Flow shall be
shut off as required, to properly rehabilitate the manhole or sewer.
B. Plugging or blocking of sewage flows shall incorporate primary' and secondary
plugging device. When plugging or blocking is no longer needed for performance
and acceptance or work, it is to be removed in a manner that permits the sewage
flow to slowly return to normal without surge, to prevent surcharging or causing
other major disturbances downstream.
3.04 FLOW BYPASS AND/OR DIVERSION PUMPING SCHEDULING
A. If the City is operating or maintaining conventional pumping facilities and/or flow
bypass and/or diversion pumping in the construction area of the present Contract,
the Contractor shall coordinate with the City as necessary to determine and effect

1.08
APPLICATION OF INSPECTION TYPE
A. The following guidelines concerning the use of CCTV and sonar shall be followed,
subject to the review and approval of the designated Engineer:
1. Generally CCTV alone shall be used for internal condition assessment
where the depth of flow of sewage is less than 25% of overall sewer
diameter for pipe diameters 24-inches or less, and 30% for pipe diameters
greater than 24-inches. The Contractor shall provide temporary by-pass
pumping to maintain the flows to meet or exceed these requirments.
2. Generally, CCTV combined with sonar, shall be used for internal condition
assessment where depth of flow of sewage varies from 25% to 75% of.
overall sewer diameter for sewers greater than 24-inches in diameter. Where
the sewer is less than 24-inches in diameter, and depth of flow of sewage
exceeds 25% and is less than 75% of overall sewer diameter, the designated
Engineer shall instruct Contractor to either: (a) continue using CCTV (where
depth of flow is only marginally greater than 25% of overall diameter) or
(b) use sonar (by damming or plugging the sewer so that depth of flow
exceeds 75% of overall diameter).
3. Generally, sonar alone shall be used where depth of flow in the sewer
exceeds 75% of overall diameter, and the level of the flow will be artificially
increased, without the risk of flooding, to ensure that the pipe is completely
surcharged.
1.09 RESPONSffiILITY FOR OVERFLOWS OR SPILLS
A. It shall be the responsibility of the Contractor to schedule and perform his work in a
manner that does not cause or contribute to incidence of overflows or spills of

shall be checked with the monitor color turned down. In the case of tube cameras
this shall be 600 lines.
\
G.
Color Constancy: To ensure the camera shall provide similar results when used with
its own illumination source, the lighting shall be fixed in intensity prior to
commencing the survey. In order to ensure color constancy, generally no variatio.n
in illumination shall take place during the survey.
1. The Contractor shall note that the designated Engineer may periodically
check both the live and picture color consistency against the color bar. Any
differences will require re-survey of the new length or lengths affected, at
the Contractor's expense.
H.
Pia vback:
1. Playback video shall be capable of a resoluti6h" of a minimum of 400 lines
recorded at standard (SP setting) VHS speed.
2. Each VHS tape shall be labeled by reference to the header record for the
survey section completed together with the following information:
a. Sequential (unique) VHS number.
b. Basin / catchment worked in.
c. Survey company name and logo.
d. Survey date.
I.
CCTV Focus/Iris/Illumination: The adjustment of focus and iris shall allow
optimum picture quality to be achieved and shall be remotely operated. The
adjustment of focus and iris shall provide a minimum focal range from 6 inches in
front of the camera's lens to infinity. The distance along the sewer in focus from the
initial point of observation shall be a minimum of twice the vertical height of the
sewer. The illumination must allow an even distribution of the light around the
sewer perimeter without the loss of contrast picture, flare out or shadowing.
J.
Sonar Survey Requirements:
1. Rates Shall Allow For:
a.
Complete structural and service assessment to the equivalent
standard as that obtained through conventional CCTV imagery.
b. The means of attenuating flow, where necessary, to facilitate
appraisal of the full sewer cross section.

c. Measurement of flow depth and silt depth.
2.
Rates shall allow for continuous output on conventional annotated
CD-ROM format of all sewers surveyed, supported by complete defect code
sheets. Additionally, silt levels shall be assessed as a percentage depth of
sewers at 25-foot intervals for each pipeline surveyed. To facilitate thiS"
requirement, and in addition, to assist in diametrical measurement
particularly where a sewer is deformed and/or where a sewer has suffered
hydrogen sulfide corrosion; screen graphic facilities shall be made available
to enable measurements to be taken in any position across the diametrical
proflle of the sewer as the sonar survey proceeds and where specifically
directed by the designated Engineer.
3.
Where combined CCTV and Sonar imagery is required," the output shall
display combined CCTV and Sonar images of the sewer being surveyed.
The sonar image shall be superimposed on -the real CCTV image as a
combined operation.
4.
Rates shall allow for a comprehensive final report on the fmdings
concerning major defects, including fractures, displaced joints~ deformation,
corrosion and lateral intrusions, as well as dominant surface features,
including encrustation and silt depths.
5.
The monitor display resolution shall be a minimum of 512 x 512 pixels.
The color palette shall have a minimum of 16 colors with text.
6.
The picture update speed shall not compromise compliance with Item A.(l)
or result in unsatisfactory picture resolution.
7.
The range of resolution shall be :t 1/10 inch.
8.
The maximum beam width of sonar energy pulse shall be no greater than 20
from the center of the transducer.
9.
The transducer shall be of the continuous scanning type.
K. Contractor's Data Quality Control Procedure:
-
,
-,
1.
The Contractor shall operate a quality control system, to be approved by the
designated Engineer, which will effectively gauge the accuracy of all survey
reports produced by the operator.
2. The system shall be such that the accuracy of reporting IS a function
particularly of:
a. The number of faults not recorded (omissions).

b. The correctness of the coding and classification of each fault
recorded.
3. The minimum levels of accuracy to be attained under the various survey
headings are as follows:
a. Header Accuracy 95%.
b. Detail Accuracy 85%.
L.
The Contractor's data quality control program shall include routine outside auditing
of the work completed by a qualified subcontractor. The qualified subcontractor
shall meet the minimum specified Contract requirements for the performance of the
work arid shall be approved in writing by the Engineer. The accuracy of the
Contractor's data shall be based on the percentage of the data confirmed correct by
the subcontractor. The minimum acceptable accuracy-of the data shall be 85%. The
general sequence of the auditing shall be as follows:
1. The Engineer shall randomly select 1 day per month, typically in the first
week of the month, and the work performed during this day shall be
reviewed and/or repeated by the qualified subcontractor.
2. If the work is greater than or equal to 85% accurate, no further outside
auditing will be required for the month unless requested by the Engineer at
his sole discretion. The cost for this audit is included in the allowances
specified in the Bid Form.

3. If the work is less than 85% accurate, the Contractor shall, at his own
expense, repeat and/or correct the work and have the work re-audited by the
qualified subcontractor.
4. If this work is still less than 85% accurate, the Contractor shall repeat and/or
correct and have the work re-audited, at his own expense, until the work is
greater than or equal to 85% accurate.
5. When this re-audited work is found to be greater than or equal to 85%
accurate, the Contractor shall have the work of another randomly selected
day in the same month reviewed and/or repeated by the qualified
subcontractor at the Contractor's own expense.
6. Steps 2 through 5 shall be repeated at the Contractor's own expense until the
selected day is 85% accurate on the initial audi.1..
7. The occurrence of five randomly selected days not achieving 85% accuracy
on initial subcontractor review will constitute cause for dismissal.
8. If the Contractor successfully meets the 85% accuracy requirement for the
initial.randomly selected day for 2 consecutive months (Step 2 above), the
Contractor may subsequently audit 1 day every other month. The Contractor
may continue auditing 1 day every other month until the initial randomly
selected day does not meet 85% accuracy, at which time it must resume
auditing 1 day every month.
3.11 COLLAPSED SEWERS/DEFECTIVE MANHOLES
A. Any sewer found with greater than 10% deformation (i.e., collapsed or near to
collapse), must be reported to the designated Engineer immediately for remedial
action. In the event of emergency, phone (XXX)XXX-XXXX.
B. Any manhole found broken, cracked, with missing covers or surcharged, must be
reported to the designated Engineer immediately for remedial action. In the event
of emergency, phone (XXX)XXX-XXXX.
C. Any sewer found where the existing conditions pose a threat of personal injury to
the public, such as a collapsed sewer with attendant depression to roadway, must be
protected by the Contractor until the Engineer arrives at the jobsite. In the event of
emergency, phone (XXX)XXX-XXXX.
D. Any manhole found where the existing conditions pose a threat of personal injury to
the public, such as broken, cracked or missing covers or covers found in traveled
portions of any sidewalk or roadway, must be protected by the Contractor until the

Internal Sewer Condition Assessment
General Inspection Logging Requirements
(to be read in conjunction with other related documentation, i.e., Manual of Sewer
Condition Classification):
The fIrst three lines of each set of survey details must have the codes ST or MH.
The Manhole Number must be entered in the Remarks column against the MIl code (this is
essential as a number of Data Interrogation packages stores the Header and Detail records
separately which are "connected" by an Index. To ensure data integrity, a QC check can be
run against the Detail information to confIrm that the correct Details are against the
relevant Header).
I.e.:
OD10230 0.0 ST
OD1 0.0 MH
OD1 0.0 WL
SJ34255521
10
Each line of Detail (or as a minimum the fIrst and last Detail lines) must have the video
digit entered against each code, presented in the following way:
- The video digits must conform to the National elapsed time based standards (time into
the tape) for Video Tape recorders:
- Always four digits (hmms, where s = units of 10 seconds).
- Always right justified and zero filled.
- The following elapsed time format MUST be adhered to, i.e.:
0230
o = Number of hours (Zero hours).
23 = Number of minutes (23 minutes).
o = Units of 10 seconds each (0 seconds).
Other examples:
0032 = 3 minutes and 20 seconds into the tape.
0244 = 24 minutes and 40 seconds into the tape.
1503 = 1 hour, 50 minutes and 30 seconds into the tape.
2451 = 2 hours, 45minutes and 10 seconds into the tape.
The final detail line for each survey must end with a Termination code, either SA or
FH.

Each Survey Report MUST only contain one survey hence, in the case of Survey
Abandonment or a buried or uncharted manhole being encountered, a new Header and
Detail must be completed.
The above are essential for the Validation of the data to take place.

SECTION 02757
Sanitary Sewer Point Repair
PART 1 - GENERAL
1.01 SCOPE
A. This section desc~bes repairs to sections of existing sanitary sewers that require
excavation from the surface to correct major defects in pipe alignment or collapse.
Point repairs are necessary external corrective open cut trench pipe
replacement/renewal construction, both as an independent solution to a specific
problem and also as supplemental work to allow another rehabilitation method to
proceed. Furnish all products and perform all labor necessary to fulfill the
requirements of these Specifications.
1.02 APPLICABLE REHABILITATION :METHODS
A. Pipe and fittings furnished for this work must comply with the requirements of
Section 02730 - Sewer and Accessories, of the Contract Documents. Replacement
pipe shall be the same size as the existing pipe and shall be laid on a uniform grade
between the ends of existing pipe which remain in place, unless otherwise indicated
in writing to be acceptable to the City. It is the Contractor's complete responsibility
to set controls as necessary to attain true line and grade for the replacement pipe.
B. Point repairs are made at specific locations and involve relatively short lengths of
sewer. Isolation of affected reaches of sewer, by plugging and/or bypass pumping if
required, shall be performed in accordance with Section 02750 - Wastewater Flow
Control, of the Contract Documents. The cost for such plugging and/or bypass
pumping shall be included in the unit bid price for point repairs.
C. Locations where point repairs are identified on the Drawings are based on
previously performed smoke tests and/or television inspection. It is understood that
the exact location of pipe leaks and failures cannot always be determined before the
pipe is exposed because the smoke injected into the existing pipe to detect their
presence can migrate through passages in the earth, overburden, and may not
emerge directly over the leak or failure. Precise location of required point repairs
shown on the Drawings is the responsibility of the Contractor, and shall be included
in the unit bid price.
D.
Mter the designated repairs have been made, the Contractor will test them as
described in this section of these Specifications. The costs of testing will be borne
by the Contractor. If a repaired joint or section should prove to be defective, the
Contractor shall re-perform the work at no additional cost to the City, and shall also

CONCRETE CURING AND PROTECTION
A. General:
1. Protect freshly placed concrete from premature drying, and excessive cold
or hot temperature, and maintain without drying at a relatively constant
temperature for a period of time necessary for hydration of cement and
proper hardening.
2. Start initial curing as soon as free water has disappeared from concrete
surface after placing and finishing. Weather permitting, keep
continuously moist for not less than 7 days.
3. Begin fmal curing procedures immediately following initial curing and
before concrete has dried. Continue final curing for at least 7 days and in
accordance with ACI 301 procedures. Avoid rapid drying at end of final
curing period.
B. Curing Methods: Perform curing of concrete by one or more of the following
methods as selected by the Contractor:
1. Provide Moist Curing: By covering concrete surfaces with specified
absorptive cover, thoroughly saturating cover with water and keeping
continuously wet. Place absorptive cover to provide coverage of concrete
surfaces and edges, with 4-inch lap over adjacent absorptive cover.
2. Provide Moisture-Cover Curing: By covering concrete surfaces with
moisture-retaining cover, placed in widest practicable width with sides and
ends lapped at least 3 inches and sealed by waterproof tape or adhesive.
Immediately repair any holes or tears during curing period using cover
material and waterproof tape.
3. Provide Membrane Curing: By applYing compound to damp concrete
surfaces as soon as film has disappeared. Apply uniformly in continuous
operation by power-spray or roller equipment in accordance with
manufacturer's directions. Recoat areas that are subjected to heavy rainfall
within 3 hours after initial application. Maintain continuity of coating and
repair damage during curing period.
4. Do not use membrane curing compounds on surfaces which are to be
covered with a coating material applied directly to concrete or with a
covering material bonded to concrete, such as other concrete, liquid floor

brush with a neat cement grout coating or concrete bonding agent. Place
patching concrete before grout takes its initial set. Mix patching concrete
of same materials to provide concrete of the same type or class as original
concrete. Place, compact and finish to blend with adjacent finished
concrete. Cure in the same manner as adjacent concrete.
6. Repair isolated random cracks and single holes not over I-inch in diameter
by dry-pack method. Groove top of cracks and cutout holes to sound
concrete and clean of dust, dirt and loose particles. Dampen cleaned
concrete surfaces and brush with neat cement grout coating or concrete
bonding agent. Place dry-pack before cement grout takes its initial set.
Mix dry-pack, consisting of one part Portland cement to 2-112 parts fine
