Re: Bid Tabulation
Sewer Main to Andrew Corporation
Dear Mr. Bunn:
Attached please find a bid tabulation for the referenced project.
The three low bidders are listed on the first page of the tabulation.
We have verified that these three bidders are currently properly
licensed. Please note that Decco Contractors, Inc. listed their
expired license number (82-2061). This company's current license
number is 83-2365. The third low bidder, Fayette Tree and Trench,
Inc., filled in the bid form improperly, listing the total bid price
in words on the Proposal line items instead of the unit bid price
in words. If their bid is to be used, an attorney's opinion should
be obtained before their bid is utilized.
Seven of the bidders submitted proper bid bonds. The eighth bidder,
North Side Construction submitted a Cashier's Check for bid security.
We are returning this check, in accordance with page 4 of the
Instructions to Bidders, which provides for returning all but the
three low bidder's bonds. North Side Construction Company was the
fifth low bidder, so the need for their bid security check is not
anticipated.
We would recommend award of a contract to the low bidder, Decco
Contractors., Inc. of Rogers, Arkansas, in the amount of $55,355.00.
This price is for a vitrified clay sewer pipe material. If the
City wishes to have truss pipe utilized, the low bidder is Tanda,
Inc., of Fort Smith, in the amount of $59,639.75.
We are working with Burlington Railroad concerning a crossing permit.
Otherwise, it is our understanding that submission of this bid review,

11. RIGHT TO REJECT BIDS. The Owner reserves the right to reject any and
all bids. All bids are subject to this reservation, and the Owner reserves
to itself the right to decide which bid shall be deemed the lowest and
best. Due consideration will be given to the reputation, financial
ability, experience and equipment of the bidder.

grant the Contractor such extension of time in executing the contract as it
deems necessary in the interest of the Owner. Any application for
extension of time shall be made by the Contractor in writing, and signed by
proper officials. The inclusion of this provision, whereby extension of
time in signing the contract and submission of bonds may be granted, in no
way obligates the Owner to act upon any application unless it sees fit to
do so.

specified time after the contract is awarded, the bid by the Contractor
will be considered to have been abandoned and the Owner may ask for new

Bidder's failure to execute said bonds and contracts within said specified
time, the bid bond accompanying the bid shall be the agreed amount of
damages which the Owner will suffer by reason of such failure upon the part
of the bidder, and shall thereupon immediately be forfeited to the Owner.
The filing of a bid under these instruction shall be considered as
acceptance of this provision.
13. RETURN OF BIDDER'S BOND. Bonds deposited with bids will be returned
to the bidders as soon as the contract is awarded, except the bond of the
successful bidder, which will be returned after the contract is executed
and the bonds approved. Unless the Owner has a good reason to hold bidding
bonds, the bonds of all except the three low bidders will be returned as
soon as the bids have been considered.
14. AWARDING OF CONTRACT. The Owner reserves the right to withhold the
awarding of a contract for a reasonable period of time from the date of

shall have been reduced to writing and duly signed by the contracting
parties. The lettering of a contract shall not be complete until the
contract is duly executed and the necessary bonds approved.

part of the Contract without the prior written approval of the Owner, nor
shall the Contractor allow such subcontractor to commence work until he has
provided and obtained approval of such compensation and public liability
insurance as may be required under the laws of the state. The approval of
such subcontract by the Owner will in no manner release the Contractor from
any of his obligations as set out in the Plans, Specifications, Contract.
and bonds.
16. PREFERENCE FOR ARKANSAS CONTRACTORS. In the event that the Project is
funded by an agency or Owner which is subject to the preference for certain
bidders set forth in Section 14 - 614.2 of the Arkansas Statutes, in order
to qualify for such preference, the Bidder must submit with his Bid a
written claim for preference listing the owners of projects upon which he
has satisfactorily performed prior contracts within the State of Arkansas
within two years of the date of the bid opening and listing the nature of
any and all taxes paid by the Bidder which support his claim for
preference. For additional information, the Bidder is referred to Arkansas
Statutes Sections 14 - 614.2 through 14 - 614.6.

product or of a particular manufacturer or vendor, any material or article
which will perform adequately the duties imposed by the general design may

inspection as stated heretofore. Should the Contractor fail to give such
timely notice and/or should the Contractor cover up, without the consent of
the Engineer, the portion of the Work to be so tested and/or inspected, the
Contractor shall, upon request of the Engineer, uncover such portion and/or
perform a retest and/or a reinspection of such portion, all at the sole
expense of the Contractor.
. The Engineer shall have the right to order special tests not required
by the Specifications and/or the Plans, whereupon the Contractor shall
promptly perform such tests. If the portion of the Work so tested proves
to be in accordance with the Specifications and the Plans, all costs
involved in such testing shall be paid for by the Owner and if such testing
delays the Work, the time within which the Work is to be completed shall be
extended by a mutually agreed to period of time. If the portion of the
Work so tested, however, proves to be not in accordance with the
Specifications and the Plans, all costs involved in such testing shall be
paid for by the Contractor and the time within which the Work is to be
completed shall be extended by a mutually agreed to period of time.
Neither observations by the Engineer nor the inspections, tests or
approvals by persons other than the Contractor shall relieve the Contractor
from his obligations to perform the Work in accordance with the requirement
of the Plans and Specifications.
DEFECTIVE WORK
If the work is defective, or the Contractor fails to supply sufficient
skilled workmen or suitable materials or equipment, the Engineer may order
the Contractor to stop the Work, or any portion thereof, until the cause
for such order has been eliminated.
If required by the Engineer prior to approval of final payment, the
Contractor shall promptly, without cost to the Owner and as specified by
the Engineer, either correct any defective Work, whether or not fabricated,

u
installed or completed, or, if the Work has been rejected by the Engineer,
remove it from the site and replace it with nondefective Work, whether or
not fabricated, installed or completed, or if the Work has been rejected by
the Engineer, remove it from the site and replace it with nondefective
Work. If the Contractor does not correct such defective Work or remove and
replace such rejected Work within a reasonable time, all as specified in a
written notice from the Engineer, the Owner may have the deficiency
corrected or the rejected Work removed and replaced. All direct or
indirect costs of such correction or removal and replacement, including
compensation for additional professional services, shall be paid by the
Contractor, and an appropriate deductive Change Order shall be issued. The
Contractor shall also bear the expenses of making good all Work of others
destroyed or damaged by his correction, removal or replacement of his
defective Work.
If, instead of requiring correction or removal and replacement of
defective Work, the Owner (and, prior to approval of final payment, also
the Engineer) prefers to accept it, he may do so. In such case, if
acceptance occurs prior to approval of final payment, a Change Order shall
be issued incorporating the necessary revisions in the Plans and
Specifications, including appropriate reduction in the Contract Price; or,
if the acceptance occurs after approval of final payment, an appropriate
amount shall be paid by the Contractor to the Owner.
If, after the approval of final payment and prior to the expiration of
one year after the date of completion, any Work is found to be defective,
the Contractor shall promptly, without cost to the Owner and in accordance
with the Owner's written instructions, either correct such defective Work,
or, if it has been rejected by the Owner, remove it from the site and
replace it with nondefective Work. If the Contractor does not promptly
comply with the terms of such instructions, the Owner may have the
defective Work corrected or the rejected Work removed and replaced, and all
direct and indirect costs of such removal and replacement, including
compensation for additional professional services, shall be paid by the
Contractor.
COMPLETION, FINAL INSPECTION, AND ACCEPTANCE
The Contractor shall notify the Engineer and the Owner ten (10) days
prior to the date on which final inspection of the Work is to be made and
shall give notification only if all work is completed.
It. shall be the duty of the Engineer to determine when the Work is
complete and the contract fulfilled, and to recommend its acceptance by the
Owner.
CHANGES IN THE WORK
Without invalidating the Construction Contract, the Owner may, at any
time or from time to time, order additions, deletions or revisions in the
Work; these will be authorized by written Change Orders. Upon receipt of a
Change Order, the Contractor shall proceed with the Work involved. All
General Provisions - 18
NCORrbflArFn

J
r
such
Work shall be
executed under
the applicable conditions of the Plans
and
Specifications.
If any Change
Order causes an increase or decrease in
the
Contract Price or an extension
or shortening of the Contract Time, an
equitable
adjustment
will be made.
The Engineer may authorize minor changes or alterations in the Work
not involving extra cost and not inconsistent with the overall intent of
the Plans and Specifications. These may be accomplished by a field order.
If the Contractor believes that any minor change or alteration authorized
by the Engineer entitles him to an increase in the Contract Price, he may
make a claim therefore.
Additional Work performed by the Contractor without authorization of a
Change Order will not entitle him to an increase in the Contract Price or
an extension of the Contract Time, except in the case of an emergency.
In emergencies affecting the safety of persons or the Work or property
at the site or adjacent thereto, the Contractor, without special
instruction or authorization from the Engineer or the Owner, is obligated
to act, at his discretion, to prevent threatened damage, injury or loss.
He shall give the Engineer prompt written notice of any significant changes
in the Work or deviations from the Plans and Specifications caused thereby,
and a Change Order shall thereupon be issued covering the changes and
deviations involved. If the Contractor believes that additional work done
by him in an emergency which arose from causes beyond his control entitles
him to an increase in the Contract Price or an extension of the Contract
Time, he may make a claim therefore.
The Owner shall execute appropriate Change Orders prepared by the
Engineer covering changes in the Work to be performed, Work performed in an
emergency, and any other claim of the Contractor •for a change in the
Contract Time or the Contract Price which is approved by the Engineer.
It is the Contractor's responsibility to notify his Surety of any
changes affecting the general scope of the Work or change in the Contract
Price and the amount of applicable Bonds shall be adjusted accordingly.
The Contractor shall furnish proof of such adjustment to the Owner.
CHANGES IN CONTRACT PRICE
The Contract price as set forth in the Construction Contract may only
be changed by a written Change Order. Any claim for an increase in the
Contract Price shall be based upon written notice delivered to the Owner in
and the Engineer within fifteen days of the occurrence of the event giving
rise to the claim. Notice of the amount of the claim with supporting data
shall be delivered within forty-five days of such occurrence unless the
Engineer allows an additional period of time to ascertain accurate cost
data. All claims for adjustments in the Contract Price shall be determined
by the Engineer if the Owner and the Contractor cannot otherwise agree on
the amount involved. Any change in the Contract Price resulting from any
such claim shall be incorporated into a written Change Order.
General Provisions - 19
r
The value of any Work covered by a Change Order or of any claim for an
increase or decrease in the Contract Price shall be determined in one of
the following ways:
(a) Where the Work involved is covered by unit prices contained the
• Contract Documents, by application of unit prices to the
quantities of the items involved.
(b) By mutual acceptance of a lump sum.
(c) On the basis of the Cost of the Work plus a Contractor's Fee for
overhead and profit. The term "Cost of the Work" means the sum
of all costs necessarily incurred and paid by the Contractor in
the proper performance of the Work. Except as otherwise may be
agreed to in writing by the Owner, such costs shall be in amounts
no higher than those prevailing in the locality of the Project
and shall include only the following items:
(1) Payroll costs for employees in the direct employ of the
Contractor in the performance of the Work under schedules of job
classifications agreed upon by the Owner and the Contractor.

Engineer, which bids will be acceptable.
(4) Costs of special consultants (including, but not limited to,
engineers, architects, testing laboratories, surveyors, lawyers
and accountants) employed for services specifically related to
the Work.
(5) The proportion of necessary transportation, traveling and
subsistence expenses of the Contractor's employees incurred in
discharge of duties connected with the Work.
(6) Cost, including transportation and maintenance, of all
materials, supplies, equipment, machinery, appliances, office and

officers, executives, principals (of partnership and sole
proprietorships), general managers, engineers, architects,
estimators, lawyers, auditors, accountants, purchasing and
contracting agents, expeditors, timekeepers, clerks and other

the Work, all of whom are to be considered administrative costs
covered by the Contractor's Fee.
(b) Expenses of the Contractor's principal and branch offices other
than his office at the site.
(c) Any part of the Contractor's capital expenses, including interest
on the Contractor's capital employed for the Work and charges

ten percent
(10%)
of items (a), (b), and (c)
included under the
term "Cost
of the
Work".
The amount of credit to be allowed by the Contractor to the Owner for
any such change which results in a net decrease in cost, will be the amount
of the actual net decrease. The Contractor's administrative costs for
processing the decrease will not be credited to the Contractor. When both
additions and credits are involved in any one change, the combined overhead
and profit shall be figured on the basis of the net increase, if any.
Whenever the cost of any Work is to be determined by the "Cost Plus"
method, the Contractor will submit in form acceptable the Engineer an
itemized cost breakdown together with supporting data.
OVERTIME WORK
As used in this Contract, "overtime work" shall be all labor hours
worked per man which are required, by applicable custom of the trade, union
contract or law, to be paid at a premium hourly rate not less than time and
one half the basic straight time hourly rate for the work performed. The
amount above such basic straight time hourly rate shall be considered the
premium for such overtime work.
Overtime work requested or authorized by the Owner in writing shall be
performed by the Contractor and the Owner shall, except in the case of
changes performed under "COST PLUS A FEE CHANGES", reimburse the Contractor
for only (a) the premium portion of the payments made for performing such
overtime work and (b) with respect to such premium portion only, any other
required payments to or for the benefit of employees and any applicable
insurance premiums and payroll taxes.

CHANGES IN
CONTRACT TIME AND LIQUIDATED DAMAGES
It is
hereby understood and mutually agreed, by
and between the
Contractor
and the Owner, that the date of beginning
and the
time for
completion
as specified in the Contract of the work to
be done
hereunder
are essential
conditions of this Contract; and it is
further
mutually
understood
and agreed that the work embraced in this
contract
shall be
commenced on a date to be specified in the NOTICE TO PROCEED.
The Contractor agrees that said work shall be prosecuted regularly,
diligently, and uninterruptedly at such rate of progress as will insure
full completion thereof within the time specified. It is expressly
understood and agreed, by and between the Contractor and the Owner, that
the time for the completion of the Work described in the PROPOSAL is a
reasonable time for the completion of the same, taking into consideration
the average climatic range and usual industrial conditions prevailing in
this locality.
If the Contractor shall neglect, fail, or refuse to complete the Work
within the time herein specified, or any proper extension thereof granted
by the Owner, then the Contractor does hereby agree, as a part
consideration for the awarding of this Contract, to pay to the Owner the
amount specified in the Contract, if any, for each and every calendar day
that the Contractor shall be in the default after the time stipulated in
the contract for completing the work.
The said amount is fixed and agreed upon by and between the Contractor
and the Owner realizing the impracticability and extreme difficulty of
fixing and ascertaining the actual damages the Owner would in such event
sustain, and said amount is agreed to be the amount of damages which the
Owner would sustain.
It is further agreed that time is of the essence of each and every
portion of this Contract and of the Specifications wherein a definite and
certain length of time is fixed for the performance of any act whatsoever;
and where under the Contract an additional time is allowed for the
completion of any Work, the new time limit fixed by such extension shall be
of the essence of this Contract. PROVIDED, that the Contractor shall not
be charged with liquidated damages or any excess cost when the Owner
determines that the Contractor is without fault and the Contractor's
reasons for the time extension are acceptable to the Engineer.
The Contract Time may only be changed by a Change Order. Any claim
for an extension in the Contract Time shall be based on written notice
delivered to the Owner and the Engineer within seven (7) days of the
occurrence of the event giving rise to the claim. Notice of the extent of
the claim with supporting data shall be delivered within thirty (30) days

r
of such occurrence unless the Engineer allows an additional period of time
to ascertain more accurate data. All claims for adjustment in the Contract
Time shall be determined by the Engineer if the Owner and the Contractor
cannot otherwise agree. Any change in the Contract Time resulting from any
such claim shall be incorporated into a Change Order.
The Contract Time will be extended in an amount equal to time lost due
to delays beyond the control of the Contractor if he makes a claim
therefore as provided in heretofore. Such delays shall include, but not be
restricted to, acts or neglect by any separate contractor employed by the
Owner, fires, floods, labor disputes, epidemics, abnormal weather
conditions, or acts of God.
NEGLECTED WORK
If the Contractor should fail to prosecute the Work in accordance with
the Plans and Specifications, including any requirements of the progress
schedule, the Owner, after seven days' written notice to the Contractor
may, without prejudice to any other remedy he may have, make good such
deficiencies and the cost thereof (including compensation for additional
professional services) shall be charged against the Contractor if the
Engineer approves such action, in which case 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 then or
thereafter due the Contractor are not sufficient to cover such amount, the
Contractor shall pay the difference to the Owner.
PROGRESS PAYMENTS
About the first day of the month, the Contractor shall submit to the
Engineer for review an Application for Payment filled out and signed by the
Contractor covering the Work completed as of the date of the Application
and accompanied by such data and schedules as the Engineer may reasonably
require. Unless otherwise specifically stated in the Detailed
Specifications, or clarified by the Owner prior to approval of the
Contract, the Owner shall pay to the Contractor ninety percent (90%) of the
amount of such estimated value of materials furnished and work done during
said previous calendar month. After fifty percent (50%) of the project has
been completed, the amount retained may be reduced to five percent (5%) of
the project has been completed, the amount retained may be reduced to five
percent (5%), provided reasonable cause cannot be shown for a greater
retainage. 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 another location agreed to in writing, the Application for Payment shall
also be accompanied by such data, satisfactory to the Owner, as will
establish the Owner's title to the material and equipment and protect his
interest therein, including applicable insurance. Each subsequent
Application for Payment shall include an affidavit of the Contractor
stating that all previous progress payments received on account of the Work
have been applied to discharge in full all of Contractor's obligations
reflected in prior Applications for Payment.
General Provisions - 24
LIA Ica�R TED
The 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 the Owner at the time of
payment free and clear of all liens, claims, security interests and
encumberance.
The Engineer will, within ten days after receipt of each Application
for Payment, either indicate in writing his approval of payment and present
the Application to the Owner, or return the Application to the Contractor
indicating in writing his reasons for refusing to approve payment. In the
latter case, the Contractor may make the necessary corrections and resubmit
the Application. The Owner shall, within ten days of presentation to him
of an approved application for payment, pay the Contractor the amount
approved by the Engineer. By approving any such payment the Engineer will
not thereby be deemed to have represented that he made exhaustive or
continuous on -site inspections to check the quality or the quantity of the
Work, or that he has reviewed the means, methods, techniques, sequences,
and procedures of construction, or that he has made any examination to
ascertain how or for what purpose the Contractor has used the moneys paid
or to be paid to him on account of the Contract Price, or that title to any
Work, materials, or equipment has passed to the Owner free and clear of any
liens.
The Engineer may refuse to approve the whole or any part of any
payment if, in his opinion, it would be incorrect to make such
representations to the Owner. He may also refuse to approve any such
payment, or, because of subsequently discovered evidence or the results of
subsequent inspections or tests, nullify any such payment previously
approved to such extent as may be necessary in his opinion to protect the
Owner from loss because:
(a) The Work is defective, or completed Work has been damaged
requiring correction or replacement;
(b) Claims or Liens have been filed or there is reasonable cause to
believe such may be filed;
(c) The Contract Price has been reduced because of Modifications;
(d) The Owner has been required to correct defective Work or complete
the Work; or.
(e) Of unsatisfactory prosecution of the Work, including failure to
furnish acceptable submittals or to clean up.
FINAL ESTIMATE AND PAYMENT
Prior to final payment, the Contractor may, in writing to the Owner
and the Engineer, certify that the entire Project is substantially complete
and request that the Engineer issue a certificate of Substantial
Completion.
General Provisions - 25
i .°e N �'Lrn
r
Within a reasonable time thereafter, the Owner, the Contractor and the
Engineer shall make an inspection of the Project to determine the status of
completion. If the Engineer does not consider the Project substantially
complete, he will notify the Contractor in writing giving his reasons
therefore. If the Engineer considers the Project substantially complete,
he will prepare and deliver to the Owner a tentative certificate of
Substantial Completion which shall fix the date of Substantial Completion
and the responsibilities between the Owner and the Contractor for
maintenance, heat and utilities. There shall be attached to the
certificate a tentative list of items to be completed or corrected before
final payment, and the certificate shall fix the time within which such
items shall be completed or corrected, said time to within the Contract
Time. The Owner shall have seven days after receipt of the tentative
certificate during which he may make written objection to the Engineer as
to any provisions of the certificate or attached list. If, after
considering such objections, the Engineer concludes that the Project is not
substantially complete, he will within fourteen days after submission of
the tentative certificate to the Owner notify the Contractor in writing,
stating his reasons therefore. If, after consideration of the Owner's
objections, the Engineer considers the Project substantially complete, he
will within said fourteen days execute and deliver to the Owner and the
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 he believed justified after
consideration of any objections from the Owner.
The Owner shall have the right to exclude the Contractor from the
Project after the date of Substantial Completion, but the Owner shall allow
the Contractor reasonable access to complete or correct the items on the
tentative list.
Prior .to final payment, the Owner may request the Contractor in
writing to permit him to use a specified part of the Project which he
believes he may use without significant interference with construction. of
the other parts of the Project. If the Contractor agrees, he will certify
to the Owner and the Engineer that said part of the Project is
substantially complete and request the Engineer to issue a certificate of
Substantial Completion for that part of the Project. Within a reasonable
time thereafter the Owner, the Contractor, and the Engineer shall make an
inspection of that part of the Project to determine its status of
completion. If. the Engineer does not consider it to be substantially
complete, he will notify the Owner and the Contractor in writing giving his
reasons therefore. If the Engineer considers that part of the Project to
be substantially complete, he will execute and deliver to the Owner and the
Contractor a certificate to that effect, fixing the date of Substantial
Completion as to that part of the Project, attaching thereto a tentative
list of items.to be completed or corrected before final payment and fixing
the responsibility between the Owner and the Contractor for maintenance,
heat and utilities as to that part of the Project. The Owner shall have
the right to exclude the Contractor from any part of the Project which the
General Provisions - 26
J
Engineer has so certified to be substantially complete, but the Owner shall
allow the Contractor reasonable access to complete or correct the items on
the tentative list.
Upon written notice from the Contractor that the Project is complete,
the Engineer will make a final inspection with the Owner and the Contractor
and will notify the Contractor in writing of all particulars in which this
inspection reveals that the Work is incomplete or defective. The
Contractor shall immediately take such measures as are necessary to remedy
this deficiencies.
After the Contractor has completed all such corrections to the
satisfaction of the Engineer and delivered all maintenance and operating
instructions, schedules, guarantees, Bonds, certificates of inspection and
other documents --all as required by the Specifications, he may make
application for final payment following the procedure for progress
payments. The final Application for Payment shall be accompanied by such
data and schedules as the Engineer may reasonably require, together with
complete and legally effective releases or waivers (satisfactory to Owner)
of all Liens arising out of the Plans and Specifications and the labor and
services performed and the material and equipment furnished thereunder. In
lieu thereof and as approved by the Owner, the Contractor ray furrish
receipts or releases in full; an affidavit of the Contractor that the
releases and receipts include all labor, services, material and equipment
for which a Lien could be filed, and that all payrolls, material and
equipment bills, and other indebtedness connected with the Work for which
the Owner or his property might in any way be responsible, have been paid
or otherwise satisfied; and consent of the Surety, if any, to final
payment.
If, on the basis of his observation and review of the Work during
construction, his final inspection and his review of the final Application
for Payment, all as required by the Plans and Specifications, the Engineer
is satisfied that the Work has been completed and the Contractor has
fulfilled all of his obligations • under the Plans and Specifications, he
will, within ten days after receipt of the Final Application for Payment,
indicate in writing his approval of payment and present the Application to
the Owner for payment. Thereupon the Engineer will give written notice to
the Owner and the Contractor that the Work is acceptable. Otherwise, he
will return the Application to the Contractor, indicating in writing his
reasons for refusing to approve final payments, in which case the
Contractor shall make the necessary corrections and resubmit the
Application. The Owner shall, within ten days of presentation to him of an
approved final Application for Payment, pay the Contractor the amount
approved by the Engineer.
If after Substantial Completion of the Work final completion thereof
is materially delayed through no fault of the Contractor; and the Engineer
so confirms, the Owner shall, upon certification by the Engineer, and
without terminating the Agreement, make payment of balance due for that
General Provisions - 27
('nfl
r
portion of the Work fully completed and accepted. If the remaining balance
for Work not fully completed or corrected is less than the retainage
stipulated heretofore, and if Bonds have been furnished as required
heretofore, 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 the Contractor to the Engineer prior to certification of 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.
The Contractor's obligation to perform the Work and complete the
Project in accordance with the Plans and Specifications shall be absolute.
Neither approval of any progress or final payment by the Engineer, nor the
issuance of a certificate of Substantial Completion, nor any payment by the
Owner to the Contractor under the Plans and Specifications, nor any use or
occupancy of the Project or any part thereof by the Owner, nor any act of
acceptance by the Owner nor any failure to do so, nor any correction of
defective work by the Owner shall constitute an acceptance of Work not in
accordance with the Plans and Specifications.
The making and acceptance of final payment shall constitute a waiver
of all claims by the Owner against the Contractor other than those arising
from unsettled Liens, from defective work appearing after final inspection,
or from failure to comply with the requirements of the Plans and
Specifications or the terms of any special guarantees specified therein,
and a waiver of all claims by the Contractor against the Owner other than
those previously made in writing and still unsettled.
Where part of the monies for construction of the project is being
obtained by grant or loan from Federal agencies, such as often is the case,
the final estimate will not be certified until the project has been
approved by the responsible Federal agency, and the final payment will not
be made until the monies are received from such agency. Consequently,
there is under such circumstances the possibility and likelihood of a delay
in making said final payment in excess of the customary period, as is the
case when the Owner has all necessary monies on hand.
GUARANTEES FOR MATERIALS, EQUIPMENT AND WORKMANSHIP
The Contractor hereby warrants that all materials and equipment
furnished for the Work and all portions of the Work:
(a) Shall be new unless otherwise authorized by the Owner in writing;

Substantial Completion thereof and the date of the Owner's
acceptance of the work in the case of materials, equipment and
portions of the Work which have been incorporated into, or
performed on, the Work by the Contractor subsequent to the Date
of Substantial Completion thereof; provided however, that the
Contractor shall not be liable for any failure which result
solely from improper operation or maintenance on the Owner's part
or which are due solely to normal wear and tear
The Contractor further warrants that all equipment designed and
manufactured by others than the Contractor which the Contractor purchases
for the Work shall be specified so as to conform to the Specifications and
to the Plans and shall be fit for the particular purposes for which they
are required.
The Contractor hereby agrees that, upon receiving written notice from
the Owner, he will at such reasonable time as is specified in such notice
repair, or remove from the Construction Site and replace any and all
materials, equipment and portions of the Work which fail to meet any
warranty applicable thereto under these provisions; provided the Owner so
notifies the Contractor within a reasonable time after such failure becomes
known to the Owner and makes the Work available for such repair or removal
and replacement. -
The Contractor hereby agrees that in the event any failure of any of
the materials, equipment orportions of the Work to meet any warranty
applicable thereto under these provisions becomes known to him, he will
notify the Owner promptly of such failure.

The Owner shall give to the Contractor prompt notice of observed
defects. All questions arising under this Article shall be decided by the
Engineer, subject to arbitration as provided herein.

dispute or other matter shall be made until the earlier of the date on
which the Engineer has rendered his decision or the tenth day after the
parties have presented their evidence to the Engineer if he has not
rendered his written decision before that date. No demand for arbitration
shall be made later than thirty days after the date on which the Engineer
rendered his written decision in respect of the claim, dispute or other
matter as to which arbitration is sought; and the failure to demand

PLACING THE CONCRETE
No concrete shall be poured without the Engineer or his representative
being present. Concrete shall be placed according to the latest revised
edition of ACI 318-77. It shall be so deposited that the mortar and coarse
aggregate are not separated. Dropping the concrete for a height of 5 feet
or more, depositing large quantities at any point and running or working it
along the form or any other practice tending to cause segregation of the
ingredients will not be allowed. It shall be compacted by vibrating,
continuous tamping, spading or slicing. Care shall be taken to fill every
part of the forms, to work the coarser aggregate back from the face, and to
force the concrete under and around the reinforcement without displacing it.
Whenever practicable, concrete work shall be deposited continuously for each
monolithic section of the work and in all cases where so directed by the
Engineer. All floors and small dimension work shall be placed full
thickness. Mass concrete shall be placed in continuous horizontal layers.
No concrete shall be placed under water unless approval of the Engineer is
obtained previous to commencement of pouring concrete. When depositing in
water is allowed, the concrete shall be carefully placed in the space in
which it is to remain in a compact mass by means of a tremie, bottom dumping
bucket or other approved method that does not permit the concrete to fall
through the water without adequate protection. Concrete shall be placed
under water only in forms which are reasonably watertight and shall not be
disturbed after being deposited.
CURING OF
CONCRETE
Concrete not protected by form work shall be cured
by covering
with
burlap, sand, earth or with suitable curing material
approved by
the
Engineer,
or by ponding. Regardless of the form of
curing used,
the
covering
shall be placed as soon as practicable after
the concrete
has
obtained
its final set. The curing will cover a sevenS
day period dating
from the
time the concrete is deposited and the covering shall be
kept
saturated
throughout the entire period. Normal curing
operations may be
dispensed
with during periods when the air temperature falls
below 45°F,
and
cold weather
concreting curing provisions shall be initiated.
COLD WEATHER CONCRETING
Concreting operations will not be permitted when a descending air
temperature falls below 40°F, nor resumed until an ascending air temperature
reaches 35°F, without specific authority from the Engineer.
When operations are authorized under such conditions, or when it is
anticipated that the air temperature will fall below 40°F before the
concrete has taken its final set, the Contractor shall furnish sufficient
canvas and framework,•or other type of housing to enclose and protect the
structure in such a way that, the air surrounding the fresh concrete can be
kept at a temperature of not less than 40°F and not more than 85°F for a
period of at least five days after the concrete is placed. Humidity shall
VA
r -
Concrete - 4
be controlled within the housing to preclude premature drying of the
concrete.
Sufficient heating apparatus such as stoves, salamanders, or steam
equipment, and fuel to furnish the required heat, shall be supplied.
"Spot"
heating will not be permitted. All water used for mixing concrete
shall be
heated to a temperature of at least 70°F, but not over 150°F. Aggregate
shall be heated either by steam or dry heat, to a temperature of
at least
/0°F, but not over 150°F. The heating apparatus shall be such as
to heat
the mass uniformly and preclude the possibility of the occurrence of hot
spots which will burn the material. The temperature of the mixed
concrete
shall not be less than 60°F when placed in the forms. As a means of
accelerating the final set and subsequent curing of concrete not to
contain
water, from one and one-half to two pounds of calcium chloride per
sack of
cement used per batch may be incorporated in the concrete mixture.
The use
of calcium chloride as an accelerator will be permitted only when
such use
is specifically approved by the Engineer.
EXPANSION JOINTS
Expansion joints shall
be placed at points indicated on the plans.
Unless shown, reinforcement
steel shall not
extend across an
expansion
joint. The break between two
adjacent sections
shall be complete.
Exposed
edges of expansion joints shall
be rounded.
Expansion joints
shall be
filled with an elastic "build

completely in a truck mixer at the point of delivery following the addition
of mixing water.
Mixer may be stationary mixers or truck mixers. Agitators may be truck
mixers •or truck agitators. Each mixer and agitator shall have attached
thereto, in a prominent place, a metal plate on which is plainly marked for
the various uses for which the equipment is designed, the capacity of the
drum container in terms of volume of mixed concrete and the speed of
rotation of the mixing drum and blades.
The truck mixer, when loaded to manufacturer's rated capacity, which
shall not exceed 57-1/2 percent of the volume of the drum of the mixer,
shall be capable of combining the ingredients of the concrete within the
specified time into a thoroughly mixed and uniform mass and of discharging
the concrete with a satisfactory degree of authority.
The agitator, when loaded to manufacturer's rated capacity, which shall
not exceed 80 percent of the volume of the drum and. of the agitator, shall
be capable of maintaining the mixed concrete in a thoroughly mixed and
uniform mass and of discharging the concrete with a satisfactory degree of
uniformity.
Mixers and agitators shall be operated within the limits of capacity
and speed of rotation designed by the manufacturer of the equipment. Units
designated as agitators shall not be used in connection with truck mixing.
When a truck mixer is used for complete mixing, each batch of concrete
shall be mixed not less than 70 nor more than 100 revolutions of the drum or
blades at the rate of rotation designated by the manufacturer of the
equipment as mixing speed. Additional mixing, if any, shall be at the speed
designated by the manufacturer of the equipment as agitating speed.
When a truck mixer is used for transporting concrete which has been
completely mixed in a stationary mixer, mixing during transportation shall
be at the speed designated by the manufacturer of the equipment as agitation
speed, and the volume of the batch shall not exceed 80 percent of the gross
drum volume.
Concrete shall be delivered to the site of the work and discharged from
the truck mixer or agitator into the forms complete within 1-1/2 hours after
the introduction of the mixing water to the cement and aggregates except
that in hot weather, or under other conditions contributing to quick
stiffening of the concrete, the maximum allowable time may be reduced by the
Engineer. Each batch shall be accompanied by a load ticket with a copy for
the inspector showing the concrete type, mixing proportions, and time mixing
began.
J
r
Concrete - 6
Slump tests shall be made from time to time of individual samples taken
at the beginning, midpoint and end of the load. If these slumps vary by
more than the tolerances specified the mixer or agitator shall not be used
unless the condition is corrected. When the specified slump is 3 inches or
less, the tolerance shall be plus or minus 1/2 inch. When the specified
slump .is greater than 3 inches the tolerance shall be plus or minus 1 inch.
Mixers and agitators•shall be examined daily for changes in condition
due to the accumulation of hard concrete or mortar or wear of blades. The
pickup and throw -over blades shall be replaced when any part or section is
worn one (1) inch or more below the original height of the manufacturer's
design. A copy of the manufacturer's design, showing dimensions and
arrangement of blades, shall be available at all times.
The concrete when discharged shall be of the consistency and
workability required for the job without the use of additional mixing water.
The rate of discharge shall be controlled by the speed of rotation of drums
in the discharge direction with the discharge gate fully open.
When approved in writing by the Engineer, central -mixed concrete which
is designed for the purpose may be transported in approved non -agitating
equipment. Bodies of this equipment shall be smooth, watertight, metal
containers, equipped with gates that will permit control of the discharge of
the concrete. Covers shall be provided for protection against the weather.
The concrete shall be delivered to the site of the work in a thoroughly
mixed and uniform mass and discharged with a satisfactory degree of
uniformity. Placement in forms shall be completed within 30 minutes after
introduction of the mixing water to the cement and aggregates.
If the concrete furnished shows erratic behavior under the field
conditions, or in regard to strength of the finished product as shown by
beams or cylinder tests or in the time of initial or final set, the
Contractor will, at once, without notice from the Engineer, cease the use of
ready -mixed concrete until such corrections in procedure are made as to
ensure work of a quality satisfactory to the Engineer.
The organization supplying concrete shall have sufficient plant
capacity and transporting apparatus to ensure continuous delivery at the
rate required. The rate of delivery of concrete during concreting
operations shall be such as to provide for the proper handling, placing and
finishing of the concrete. The rates shall be such that the interval
between batches shall not exceed 20 minutes. The methods of delivering and
handling the concrete shall be such as will facilitate placing with the.
minimum of rehandling and without damage to the structure of the concrete.
EXCLUSION OF CONTACT WITH ALUMINUM
Due to the adverse effect of exposing concrete to direct contact with
aluminum products, concrete truck chutes, pipes, finishing tools, etc. shall
LYA ru��i fl' 8
r �
Concrete - 7
not be constructed of aluminum. Furthermore, permanent items of
construction (i.e., anchor frames, weirs, grating, etc.) made from aluminum
shall be isolated from finished concrete through the use of bitumastic or
gasket material.
HOT WEATHER CONCRETING
Concreting operations will not be permitted when an ascending air
temperature rises above 100°F, nor resumed until a descending temperature
reached 95°F, without specific authority from the Engineer.
When operations are authorized under such conditions, or when it is
anticipated that the air temperature will rise above 95°F before the
concrete has taken its final set, the Contractor shall make whatever
provisions are necessary to insure that the relative humidity immediately
adjacent to the concrete surface(s) does not fall below the following
prescribed values for a period of at least five days after the concrete is
placed (approved "curing compounds" or "sealers" will satisfy this
requirement):

During hot weather, the temperature of the mixing water may be
decreased 50 45°F; however, ice shall not be directly added to the concrete
mix.
REPAIRING/REPLACING DEFECTIVE CONCRETE
All concrete which, upon removal of the forms, is found to be porous or
"honey -combed" shall be immediately cut out and removed entirely from the
body of the concrete. The parts removed shall extend not less than one inch
(1") back of the reinforcement steel where such steel is present in the
concrete face which is being repaired, removing sound concrete, if
necessary, to obtain this depth. If reinforcement steel is not present, the
parts removed shall extend into the concrete not less than three inches (3")
and the opening dovetailed in such a manner that the new concrete filling
will be securely anchored. In replacing concrete so removed, forms shall be
built with a spout or hopper outside the concrete surface, which shall be
J
rivii
r
Concrete - 8
filled with fresh concrete to a point not less than twelve inches (12")
above the top of the hole caused by removing the porous concrete.
The fresh concrete shall be properly bonded to the old concrete
surfaces, as hereinbefore specified, and shall be well puddled. The hopper
shall be removed after the concrete has hardened and within twenty-four
hours after the concrete is placed, the excess concrete carefully cut away,
and the surface pointed and rubbed smooth.
Concrete already in place which is suspected of being defective
(because of "low breaks" on cylinder testing) shall be core -drilled at the
Engineer's direction and at the Contractor's expense. Should compressive
testing of the cored sample verify that the concrete is defective, then the
Engineer may direct the Contractor to remove defective portions and replace
them with satisfactory material, all at the contractor's expense.
The
Contractor may, at his
own expense, have portions of the
suspected
-defective material
cored and tested in order
to reduce the expense
on his
part. To accomplish
this,
he must core and
test at least three
samples
for each 200 square
feet
of exposed surface
area. Results must
indicate
that all of three
of the
samples meet, or
exceed, the required
strength
specifications.
REMOVAL OF FORMS AND BACKFILLING
Forms shall not be disturbed until the concrete has adequately
hardened. Shoring shall not be removed until the member has acquired
sufficient strength to support its weight and the load upon it. Members
subject to additional loads during construction shall be adequately shored
to support both the member and construction loads in such a manner as will
protect the member from damage by the loads; this shoring shall not be
removed until the member has acquired sufficient strength to support safely
its weight and the load upon it. The following table gives the minimum time
which shall elapse between the time of placing the concrete and the removal
of forms at various average temperatures.

(b) Relation to Water Mains
(1) Horizontal Separation - Sewers'shall be laid at least 10 feet
horizontally from any existing or proposed water main. The
distance shall be measured edge to edge. In cases where it is not
practical to maintain a ten foot separation, the Engineer may
allow installation of the sewer closer to a water main, provided
that the water main is in a separate trench or on an undisturbed
earth shelf located on one side of the sewer and at an elevation
so the bottom of the water main is at least 18 inches above the
top of the sewer.
(2) Crossings - Sewer crossing water mains shall be laid to
provide a minimum vertical distance of 18 inches between the
outside of the water main and the outside of the sewer. This
shall be the case where the water main is either above or below
the sewer. The crossing shall be arranged so that the sewer
joints will be equidistant and as far as possible from the water
main joints. Where a water main crosses under a sewer, adequate
structural support shall be provided for the sewer to prevent
damage to the water main.
(3) Special Conditions - When it is impossible to obtain proper
horizontal and vertical separation as stipulated above, the
sewer shall be designed and constructed equal to water pipe,
and shall be pressure tested to assure watertightness prior
to backfillind.

and Detailed Specifications shall apply.
4. QUALITY OF THE PLANS. The Plans have been made with care but cannot be
assumed to be correct in every detail when many of the conditions to be
encountered are not shown on existing maps and are underground.
The approximate location of existing underground water, and utility
lines are shown. The placing of this information on the Plans in no way
obligates the Owner as to its correctness, as it is indicative only and is
placed there for the information and assistance to the. Contractor.
L
►iw
It is the expressed intent of these Plans and Specifications that the
Contractor is to make his own investigation of conditions to be
encountered, including rock and underground water, and the submission of
the Proposal by the Contractor for the work constitutes his compliance with
this requirement.
5. ALTERATION OF PLANNED QUANTITIES AND CONDITIONS. The Owner reserves
the right to alter the location, grade and other conditions pertaining to
the items of construction within the Contract if it is deemed to be in the
best interest to provide the needed service and/or facilitate construction.
Likewise, the Owner may order a change in the quantity of any item, in
which case the cost to the Owner for those set items shall be based upon
the unit prices bid in the Proposal. In addition, certain items may be
deleted, in which case credit to the Owner will be determined also by the
unit prices in the Proposal.
6. COOPERATION WITH THE
OWNER. Since the work
to be done
involves the
connection of sewer mains
to those existing mains
belonging to
the City of
Fayetteville, the closest
cooperation between the
Contractor
and the City
is required. The Contractor
shall be liable for
all damages
of whatever
type that he may cause to
the Owner's facilities.
7. PROXIMITY TO EXISTING UTILITIES. The sewer main to be constructed
hereunder will be placed in easements presently occupied by electrical
power lines. The easement may be used for other utilities in the future.
The Contractor shall exert every effort so that the existing utility lines
will not be disturbed nor service interrupted. An attempt has been made to
provide information relative to the location and existence of these lines
but in some cases it may be that the information is incorrect or
incomplete. The Contractor shall maintain close cooperation with the
facilities engineer to ascertain the validity of the information supplied.

workmanship, design, or material for a period of one year from date of
final acceptance and shall repair or replace any defects occurring during
this period without cost to the Owner and to the complete satisfaction of
the Engineer.
10. PLANS AND SPECIFICATIONS. The Plans and Specifications are to be
construed according to full intent, meaning and spirit when taken either
together or separately. Plans and Specifications taken co -jointly shall be
deemed to explain each other and be descriptive of necessary work to be
performed under this contract. Any apparent discrepancy in either Plans or
Specifications shall be promptly reported to the Engineer, who is the sole
interpreter of the meaning of the Plans and Specifications, and his
directions shall be followed. If anything is shown on the Plans and not
mentioned in the Specifications, or vice -versa, the work shall be fully
executed and carried out the same as if mentioned in the Specifications and
shown on the Plans.
11. SITE .INSPECTION. The Contractor shall inspect the site, study
existing conditions, check with Plans and Specifications, and be fully
informed as to work required to complete the Contract. No allowance will
be made for misunderstanding after the contract has been awarded..
12. FEES, PERMITS, ETC. The Contractor shall pay all fees, licenses,
permits, inspections, etc., incurred in obtaining services and installing
work and shall deliver to the Owner at completion of the job all permits,
inspections approvals, etc.
13. TRENCHING AND BACKFILLING. Trenching shall be conducted as described
under General Specifications entitled Water and Sewer Pipe Laying contained
herein. Trenching through rock shall be carried down past the prescribed
grade a minimum distance of six (6) inches. Further excavation may be
ordered by the engineer if, in his opinion, conditions so warrant to
prevent future breaking of the pipe. A fine crushed material, sand or loam
shall be used above the rock. to cushion the pipe. Backfilling shall be
conducted in a workmanlike, conscientious manner. The trench shall be
backfilled in "lifts" not to exceed six (6) inches, each lift being tamped
by hand or mechanical means prior to placing the succeeding six inch lift.
This procedure shall be followed until a minimum of twelve inches of
material has been placed over the bell of the pipe. Material placed thusly
shall consist of only sand/clay material. No large stones, frozen lumps,
broken concrete, asphalt or other large, hard material shall be used in the
first 24 inches of the backfill. Backfilling of street crossings and
driveways shall be done entirely in six inch lifts using SB-2 or similar

granular, non -plastic material. No power equipment normally used to push
or dump earth material shall be used. Hand filling and mechanical or hand
tamping will be required, and the Engineer may direct that the fill
.materials be slightly moistened to. assist in its consolidation. Materials
saturated with water will not be used in the backfill. Backfill material
shall be. consolidated until it reaches a density equal to that found in the
undisturbed earth adjacent to the trench. Trenches cut for sewer main
installation shall be hand -graded to eliminate high and low places, thus
preventing beam action of the pipe. Hand grading of the trench bed and/or
bedding material shall be required for proper support of the pipe.
No extra payment will be made for any special bedding or backfill materials.
which may be required.
14. CLEAN UP. Cleaning the job site as work proceeds shall be of critical
importance under this contract. The Contractor shall be required to
maintain a separate crew, as necessary, to clean up and remove debris
immediately behind the pipe laying crew, or to otherwise provide for proper
and thorough clean up. Failure to perform this function will result in an
order from the Engineer to cease laying pipe or to cease performing other
work until the clean up is complete. Good public relations are an
essential part of this work, and the Contractor is hereby advised
accordingly. Part of the consideration in keeping the job clean lies in
constructing manholes immediately following the pipe laying operation. In
similar fashion, the Contractor shall construct manholes promptly and
backfill each as rapidly as possible.
15. ROCK EXCAVATION. Rock excavation shall be a separate pay item in this
project. Paragraph 13 of these Detailed Specifications describes the depth
of excavation below the pipe, and the cushioning material and method of
safe -guarding the pipe. Rock is defined, for the purposes of these
Specifications, as sandstone, hard shale, limestone or very hard chert
which cannot be removed without the use of an air hammer or by drilling and
blasting. Boulders larger than 1/4 cubic yard in size shall be classified
as rock also for compensation purposes. The Contractor shall exercise
extreme care in blasting. See the requirements pertaining to insurance in.
the General Provisions of these Specifications. The Contractor hereunder
shall be required to furnish evidence of blasting insurance in the amounts
shown.
METHOD OF MEASUREMENT AND BASIS FOR PAYMENT
Rock excavation will be measured daily in the open trench, only after
the Engineer has determined that the excavation qualifies as rock
excavation. The length of rock excavated, multiplied by the depth,
multiplied by the width shall determine the quantity. of rock excavation.
The maximum width of rock excavation, for pay purposes shall be thirty
inches (30"). The quantity of rock excavation so determined will be paid
for at the unit price bid in the Proposal.
