AFFIDAVIT RE PROVISION OF INSURANCE
I have discussed the insurance requirements of this project with my insurance
provider and have supplied them with the portion of the Instructions for Bidders that
contains the insurance specification. My insurance provider has agreed to complete the
"Standard Certificate of Insurance Form for the City of Irving" without modification and
to provide the coverages required by the insurance specifications without substitutions. I
understand that a failure to provide the insurance coverages required, and proof of same
on an unmodified "Standard Certificate of Insurance Form for the City of Irving" is
grounds for rejecting my bid.

Failure to comply with the contractual provisions of a City of Irving construction contract or failure to
diligently pursue a project to completion shall be a basis for the City Council rejecting a future bid
` ~ from said Contractor.
G.7.7. Failure to Complete on Time: The time of completion of the contract is of the essence. For each
`- working day that any work shall remain uncompleted after the time specified in the proposal and
contract, plus any authorized time extension granted in writing by the City of Irving, or as
automatically increased by additional work or materials ordered after the contract is signed, the sum
- per day of 1/500 of the amount of the contract (to an amount not to exceed $500.00 per day), unless
otherwise specified in the special provisions, will be deducted from the moneys due the Contractor, not
as a penalty but as liquidated damages.
The sum of money thus deducted for such delay, failure or noncompletion is not to be considered as a
penalty, but shall be deemed, taken and treated as reasonable liquidated damages, since it would be
_. impracticable and extremely difficult to fix the actual damages.
The Contractor shall also indemnify and hold t
defense fees from any property damage claims
Contractor's negligent performance or undue delay
he City harmless including paying court costs and
resulting from restriction of access caused by the
G-20
G.7.8. Suspension by Court Order: The Contractor shall suspend such part or parts of the work ordered by the

G.7.9. Temnorarv Sus nne lions: The Engineer shall have the authority to suspend the work wholly or in part
_ for such period or periods as he may deem necessary due to unsuitable weather conditions as are
considered unfavorable for the suitable prosecution of the work. If it should become necessary to stop
the work for an indefinite period, the Contractor shall store all materials in such a mannerthat they will
not obstruct or impede the public unnecessarily nor become damaged in any way and he shall take
every precaution to prevent damage or deterioration.
G.7.10. Abandonment by Contractor: In case the Contractor should abandon and fail or refuse to resume work
`" within ten (10) days after written notification from the City or the Engineer, when such orders are
consistent with the Contract Document, then, and in that case, where a performance bond exists, the
Surety on the bond shall be notified in writing and directed to complete the work, and a copy of said
r notice shall be delivered to the Contractor.
After receiving said notice of abandonment, the Contractor shall not remove from the work any
-- materials, equipment, tools, or supplies then on the job, but the same, together with any materials and
equipment and under contract for the work may be held for use on the work by the City of the Surety
on the construction bond, or another contractor in completion of the work; and the Contractor shall not
- receive any rental or credit therefore (except when used in connection with Extra Work where credit
shall be allowed as provided for under Article G.4.5., Extra Work), it being understood that the use of
such equipment and materials will ultimately reduce the cost to complete the work and be reflected in
_- the final settlement.
G.7.11. Termination of Contract: The contract will be considered fulfilled, save as provided in any
_._ maintenance stipulations, bond, or by law, when all the work has been completed, the final inspection
made by the Engineer, and final acceptance and final payment made by the City.

- - amount of work to be done and materials to be furnished under this contract may differ somewhat from
these estimates, and that where the basis for payment under this contract is the unit price method,

anticipated profits or otherwise on account of any differences which may be found between the
quantities of work actually done, the material actually furnished under this contract and the estimated
quantities contemplated and contained in the proposal; provided, however, that in the case the actual
quantity of any major item should become as much as 25% less than the estimated or contemplated
quantity for such items, then either party to this Agreement, upon demand, shall be entitled to a revised
consideration upon the portion of the work above or below 25% of the estimated quantity.
G21

2.2. STERILIZATION OF WATER LINES AAlT) FTTTTNC;S
The Contractor shall sterilize all gaskets, pipe lines and appurtenances installed by him before they are put
into services. Sterilization shall be done in the following manner:
All gasket materials shall be dipped in a strong solution of HTH, or similar chlorine compound solution
just before use in the pipe.
Prior to chlorination, the main shall be flushed as thoroughly as possible with the water pressure from
outlets available. Each valved section of newly laid pipe shall be flushed independently. This shall be
done after the pressure test and may be done either before or after the trench has been backfilled.
Methods: 1 Chlorine Liquid or Gas
2 Hypochlorite Solution
3 Dry Hypochlorite
1. A chlorine gas-water mixture shall be applied by means of a solution-feed chlorinating device or, if
approved by the Engineer, the dry gas may be fed directly through proper devices for regulating the
rate of flow and providing effective diffusion of the gas into the water within the pipe being treated.
15042-1
4/92
,.._ Chlorinating devices for feeding solutions of the chlorine gas or the gas itself must provide means of
preventing the backflow of water into the chlorine cylinder.
_.._ 2. On approval by the Engineer, a mixture of water and chlorine-bearing compound of known chlorine
content may be substituted as an alternate for liquid chlorine.
_ The point of application for methods 1 and 2 shall be at the point of filling of the pipeline extension, or
any valved section of it, and through a corporation stop inserted in the top of the newly laid pipe. The
water injector for delivering the chlorine-bearing solution into the pipe should be supplied from a tap
_, on the pressure side of the gate valve controlling the flow into the pipeline extension.
3. As a joint of clean pipe is laid and just prior to the laying of the succeeding joint a measured amount of
I-iTH or equal shall be placed in the joint with a spoon. When new lines are ready for the water test,
they shall be filled very slowly so as not to wash the chlorine compound to one end of the newly laid
line.
The strength of the chlorine mixture in the pipe line shall be such that, after filling, it shall test at least 50
part per million. The solution shall remain in the pipeline for at least 6 hours. At the end of the 6 hour
period, if it does not test 10 PPM, it shall remain in the line an additional hour for each part below
10 PPM.
Where existing mains are cut, when that portion is put back or reconnected, it shall be treated with a strong
solution of HTH or equal.
