provided, however, that in case the actual quantity of any major item
should become as much as 20% more than, or 20% 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 20% of the estimated quantity.
A "Major Item" shall be construed to be any individual bid item incurred
in the proposal that has a total cost equal to or greater than five (5)
per cent of the total contract cost, computed on the basis of the proposal
quantities and the contract unit prices.
Any revised consideration is to be determined by agreement between the
parties, otherwise by the terms of this Agreement, as provided'under
"Extra Work",

pos-session of an use any completed or partially completed portions of the
work, notwithstanding the time for completing the entire work or such
portions may not have expired but such taking possession and use shall
not be deemed an acceptance of any work not completed in accordance with
the Contract Documents. If such prior use increases the cost of or delays
the work, the CONTRACTOR shall be entitled to such extra compensation, or
extension of time, or both, as the ENGINEER may determine.
The CONTRACTOR shall notify the ENGINEER when, the the CONTRACTOR'S opinion,
the contract is "substantially completed" and when so notifying the ENGINEER►

5`08 PAYMENTS WITHHELD. The OWNER may, on account of subsequently dis-
cove`r__ed evince, w old or nullify the whole or part of any certificate
to such extent as may be necessary to protect himself from loss on account
of:
(a) Defective work not remedied.
(ti) Claims filed or reasonable evidence indicating probable filing
of claims.
(c) failure of the CONTRACTOR to make payments properly to sub-
contractors or for material or labor.
(d) Damage to another contractor.
(e) Reasonable doubt that the work can be completed for the unpaid
balance of the contract amount.
(f) Reasonable indication that the work will not be completed within
the contract time.
When the above grounds are removed or the CONTRACTOR provides a Surety Bond
satisfactory to the OWNER, which will protect the OWNER in the amount with-
held, payment shall be made for amounts withheld because of them.
5.09 DELAYED PAYMENTS. Should the OWNER fail to make payment to the CON-
R.fi R o t e sum named in any partial or final statement, when payment
is due, then the OWNER shall pay to the CONTRACTOR, in addition to the sum
shown ,as due by such statement, interest thereon at the rate of'Six (6) per
cent per annum, unless otherwise specified, from date due as provided under
"Partial 'Payments" and "Final Payments"i until fully paid, which shall fully
liquidate any injury to the CONTRACTOR growing out of such delay in payment,
but the right is expressly reserved to the CONTRACTOR in the event payments
be not promptly made,, as provided under "Partial Payments", to at any time
thereafter treat the contract as abandoned by the OWNER and recover com-
pensation, as provided under "Abandonment of Contract", unless such payments
are withheld in accordance with the provisions of "Payments Withheld
6. EXTRA WORK AND CLAIMS
6.01 CHANGE ORDERS: k!ithout invalidating this Agreement, the OWNER may,
a any time or from time to time, order additions, deletions or revisions
to the work; such changes will be authorized by Change Order, to be prepared
by the ENGINEER for execution by the OWNER and the CONTRACTOR. The Change
Order shall set forth the basis for any change in contract price, as here-
inafter set forth for Extra Work, and any change in contract time which may
result from the change.
In the event the CONTRACTOR shall refuse to execute a Change Order which has
been prepared by the ENGINEER and executed by the OWNER, the ENGINEER may
21
10-15-11
in writing instruct the CONTRACTOR to proceed with the work as set forth
in the Chatir Order and the CONTRACTOR may make claim against the OWNER
.'or Extra Work involved therein, as hereinafter provided.
6.02 MINOR CHANGES: The ENGINEER may authorize miner charrjw, in the work
not inconsistent with the overall intent of the Contract Dr,currients and
not involving an increase in Contract Price. If the CONTRACTOR believes
that any minor change or alteration authorized by the ENG11%U R involves
Extra Work and entitles him to an increase in the Contract Prite, the
CONTRACTOR shall make writter request to the ENGINEER for a written Field
Order.
In such case, the CONTRACTOR by copy of his communication to the ENGINEER
or otherwise in writing shall advise the OWNER of his request to the ENGINEER
for a written Field Order and that the work involved may result in an increase
in the Contract Price.
Any request by the CONTRACTOR for a change in Contract Price shall be made
prior to beginning the work covered by the proposed change.
6.03 EXTRA WORK. It is agreed that the basis of compensation to the CON-
OR Tor work either added or deleted by a Change Order or for which
a claim for Extra Work is made shall be determined by one or more of the
following methods:
Method (A) - By agreed unit prices; or
Method (B) By agreed lump sum; or
Method (C)`- If neither Method (A) nor Method (B) be agreed'' upon before
the Extra Work 'is commenced, then the CONTRACTOR Shall be
paid the "actual field cost" of the work, plus fifteen (l5)
per tent.
In the event said Extra Work be performed and paid for under Method (C)' then
the PProvisions of this paragraph shall apply and the "actual field costa is
hereby defined to include the cost to the CONTRACTOR, of all workmen such
as foreman, timekeepers, mechanics and laborers, and materials, supplies,'
teams, trucks, rentals on machinery and equipment, for the time actually
employed or used on such Extra Work, plus actual transportation charges
necessarily incurred, together with all power, fuel, lubricants, water and
similar operating expenses, also all necessary incidental expenses incurred
directly on account of such Extra Work, including Social Security, Old Age'
Benefits and other payroll taxes, and, a rateable proportion of premiums on
Performance and Payment Bonds and Maintenance Bonds, Public Liability and
Property Damarge-and Workmen's Compensation, and all other insurance as may
be required by any law or ordinance, or directed by the OWNER, or by them
agreed to. The ENGINEER may direct the form in which accounts of the "actual
field cost" shall be kept and the records of these accounts shall be made
available to the ENGINEER. The ENGINEER or OWNER may also specify in writing,
22
10-15-71
before the work commences, the method of doing the work and the type and
kind of machiner; and equipment to be used, otherwise these matters shall
be determined by the CONrRACTOR. Unless otherwise agreed upon, the prices
for the use of machinery and equipment shall be determined by using 100
per cent, unless otherwise specified, of the latest schedule of Equipment
Ownership Expense adopted by the Associated General Contractors of America.
Where practicable the terms and prices for the use of machinery and equip-
ment shall be Incorporated in the Written Extra Work, Order. The fifteen
(15%) per cent of the "actual field cost" to be paid the CONTRACTOR shall
cover and compensate him for his profit, overhead, general superintendence
and field office expense, and all other elements of cost and axpense not
embraced within the "actual field cost" as herein defined, save that where
the CONTRACTOR'S Camo or Field Office must be maintained primarily on ac-
count of such Extra Oork; then the cost to maintain and operate the same
shall be included in the "actual field cost".
No claim for Extra Work of any kind will be allowed unless ordered in
writing by the ENGINEER. In case any orders or instructions, either oral
or written, appear to the CONTRACTOR to involve Extra Work for which he
should receive compensation or an adjustment in the construction time, he
shall make written request to the ENGINEER for written order authorizing
such Extra Work. Should a difference of opinion arise as to what does or
does not constitute Extra Work, or as to the ppayment therefor, and the
ENGINEER insists upon its performance, the Cbl{TRACTOR shall proceed with
the work after making written request for written order and shall keep an
accurate' account of-the "actual fidld cost" thereof, as provided under
Method (C), The CONTRACTOR will thereby'preserve the right to submit the
matter of 'payment to arbitration, as hereinbelow provided.
6.04 TIME OF FILING CLAIMS. It is further agreed by both parties hereto
L at a questions of sputa or adjustment presented by the CONTRACTOR
shrill be in writing and filed with the ENGINEER within thirty (30) days
after the ENGINEER has given any d rections, order or instruction to which
the CONTRACTOR desires to take exception. The ENGINEER shall reply within
thirty (30) days to such written exceptions by the CONTRACTOR ar.J render
his final decision in writing. In case the CONTRACTOR should appeal from
the ENGINEER'S decision, any demand for arbitration shall be filed w'."
the ENGINEER and the OWNER in writing within ten (10) days after the date
of delivery to CONTRACTOR of the ENGINEER'S final decision. It is further
agreed that final acceptance of the stork by the OWNER and the acceptance
by the CONTRACTOR of the final payment shall be a bar to any claims by `
either party, except where noted otherwise in the Contract Documents.
6.05 ARBITRATION, All questions of dispute under this Agreement shall be
submitted to arbitration at the request of either party to the dispute. The
parties may agree upon one arbiters, otherwise, there shall be three, one
named in writing by each party, and the third chosen by the two arbiters so
selected; or if the arbiters fail to select a third within ten (10) days,
he shall be chosen by a District Judge serving the County in which the major
23
10-15-71
portion of the project is located, unless otherwise specified. Should the
party demanding arbitration fail to name an art::ter within ten (10) days
of the demand, his right to arbitrate shall lapse, and the decision of the
ENGINEER shall be final and binding on him. Should the other party fail
to choose an arbiter within ten (10) days, the ENGINEER shall appoint such
arbiter. Should either party refuse or neglect to supply the arbiters with
any papers or info nation demanded in writing, the arbiters are empowered
by both parties to take ex party proceedings.
The arbiters shall act with promptness. The decision of a;v t;,o shall be
binding on both parties to the contract. The decision of tv.e arbiters upon
any question submitted to arbitration under this contract shalt be a condition
precedent to any right of legal action. The decision of the arbtt'ar or
arbiters may be filed in court to carry it into effect.
The arbiters, if they deem the case demands it, are authorized to award the
party whose contention is sustained, such sums as they deem proper for the
time, expense and trouble incident to the appeal, and if the appeal was taken
without reasonable cause, they may award damages for any delay occasioned
thereby. The arbiters shall fix their own compensation, unless otherwise
provided by agreement, and shall assess the cost and charges of the arbitra-
tion upon either or both parties. The award of the arbiters must be made
in writing.
7. ABANDONMENT OF CONTRACT
7.01 ABANDONMENT BY.CONTRACTOR. In case the CONTRACTOR should,abandon,
an fa or refusF to resume work within ten (10) days 'after written notifi-
cation from the OWNER, orAhe ENGINEER, or if the CONTRACTOR fails to-comply
with the orders of the ENGINEER, when such orders are consistent with the
Contract Documents, then, and in that case, whore performance and payment,
bonds exist, the Sureties on these bonds shall be notified in writing iand
directed to complete the work, and a copy of said notice shall be delivered
to the CONTRACTOR.
After receiving said notice of abandonment the CONTRACTOR shall not remove
from the work any machinery, equipment, tools, materials or supplies then
on the Job, but the same, together with any materials and equipment under
contract for the work, may be held for use on the work by the OWNER or the
Surety on the performance bond, or another contractor in completion of the
work; and the CONTRACTOR shall not receive any rental or credit therefor
(except when used in connection with Extra Work, where credit shall be
allowed as provided for under Section G, Extra Work and Clam s), 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 settle-
ment.
Where there is no performance bond provided or in case the Surety „nould
fail to commence compliance with the notice for completion hereinbefore

OWNER ma hen the
y provide for completion of the work in either of the following
elective manners:
7.01.1 The OWNER may thereupon employ such force of men and use suet
mac nery, equipment, tools, materials and supplies as said OWNER may deem
necessary to complete the work and charge the expense of such labor, machinery,
equipment, tools, materials and supplies to said CONTRACTOR, aid expense so
charged shall be deducted and paid by the OWNER out of such moneys as may
be due, or that may thereafter at any time become due to the CONTRACTOR under
and by virtue of this Agreement. In case such expense is less than the sum
which would have been payable under this contract, if the same had been
completed by the CONTRACTOR, then said CONTRACTOR shall receive the difference.
In case such expense is greater than the sum which would have been payable
under this contract, if the same had been completed by said CONTRACTOR, then
the CONTRACTOR and/or his Surety shalt pay the amount of such excess to the
OWNER; or
7.01.2 The OWNER under sealed bids, after five (5) days notice published
one or more times in a newspaper having general circulation in the, county of
the location of the work, may let the contract for the completion of the
work under substantially the same terms and conditions which are provided
in this contract. fn case any increase in 'cost to the OWNER under the new
contract as com ared to what would have been the cost under this c ntrac
such increase shall be thaYged to the CON1'RACTO?'and 'the Surety'sh 11' be
and remain''bdund ther6foe. However, should the cost to coHpiete-, y ~qch,
new`cotltraCtIprove to'be'.lest than what'would have been the Zdst tq 1 11 oinptete
under this contract,' the CONTRACTOR and/or his Surety shali'bo`credi~ed
therewith:
When the work shall have been substantially completed the CONTRACTOR and
his Surety shall be so notified and Certificates of Completion„ and'Acceptance,
as provided in Paragraph 5.06 hereinabove, shall be issued. ' A .oniplets
itemized stet y
event of the contract accounts, certified to by the RdIN M
as being correct, shall then be prepared and delivered to ttre CONTRACTOR
and his Surety, whereupon the CONTRACTOR and/or his Surety, or the C1dNER
as the case may bo; shall pay the balance due as reflected by said state-
ment, within fifteen (15) days after the date of such Certificate of
Completion.
In the event the statement of accounts shows that the cost to complete the
work is less than that which would have been the cost to the OWNER had the
viork been completed by the CONTRACTOR under the terms of this contract; or
when the CONTRACTOR and/or his Surety shall pay the balance shown to be due
by them to the OVER, then all machinery, equip,nent, tools, materials or
supplies left on the site of the work shall be turned over to the CONTRACTOR
and/or his surety. Should the cost ~,o complete the work exceed the contract
price, and the CONTRACTOR and/or his Surety fail to pay the amount due the
OWNER within the time designated hereinabove, and there remains any machinery,
equipment, tools, materials or supplies on the site of the work, notice
26
10-15-71
thereof, together with an itemized list of suoh equipment and materials,
shall be'in6iled to the CONTRAOTOR and his Surety at the respect+ae addresses
designated in this contract, provided, however, that actual written notice
given in any manner will satisfy this condition. After mailing, or c'.her
giving of such notice, such property shall be held at the risk, of the CON-
TRACTOR and his Surety subject only to the duty of the OWNER to exercise
ordinary care to protect such property. After fifteen (15) days from the
date of said notice the OWNER may sell such machinery, equipment, tools,
materials or supplies and apply the net, sum derived from such sale to the
credit of the CONTRACTOR and his Surety. Such sale may be rade at either
public or privat,, sale, with or without notice, as the OWNER may elect.
The OWNER shall release any machinery, equipment, tools, materials, or
supplies, which remain on the work, and belong to persons other than the
CONTRACTOR or his Surety, to their proper owners. The books on all opera-
tions provided herein shall be open to the CONTRACTOR and his Surety.
7.02 ABANDONMENT BY OWNER. In case the OWNER shall fail to comply with
the terms of this c ontract, and should fail or refuse to comply with said
terms within ten (10) days after written notification by the CONTRACTOR,
then the CONTRACTOR may suspend or wholly abandon the work, and may remove
therefrom 611 machinery, tools and equipment, and all materials on the
site of work that have not been included in payinents.to the CONTRACTOR
and have not been wrought into the work. And .thereupon the ENGINEER shall
make an estimate of the total' amount earned by the CONTRACTOR, which esti
mate'shall'fnclude the value,'of all work actuAlly completed;by said
CONTRAACTOA'Cat the prices stated in the attached proposal whore unit prices
are useay,'the~value'of'all partially completed work-at a fair, and equitable
pr1re, and the 'amount of all Extra Work performed at the prices agreed upon,
or provided far by the terms of this contract, and a reasonable sum to cover
the cost of any provisions made by the CONTRACTOR to carry the whole work
to completion and which „cannot be utilized. The ENGINEER shall then make
a final statement of the balance due the CONTRACTOR by deducting from the
above n timate'all previous payments by the OWNER and all other sums that
may be retained by the OWNER tinder the terms of this Agreement and shall

DENTON, TEXAS
ELEVATED TANK FOUNDATION, PIPING,
AND APPURTENANCES
DETAIL SPECIFICATIONS
ITEM 1 - EXCAVATION AND BACKFILL
1.1 STRUCTURAL EXCAVATION: The Contractor shall make excavations required
Tor tFie construction of all concrete foundations to the lines and grades
indicated on the Plans. Excavation shall extend a sufficient distance from
walls and footings to allow for forms, installation of services, and for
inspection, except where concrete for walls and footings is authorized or
required to be deposited directly against excavated surfaces. Where the
excavation depth exceeds plan grade, the extra depth shall be filled with
lean concrete or other approved material at the expense of the Contractor.
All loose soil and humus shall be removed from the entire area within the
ringwall.
1.2 TRENCH EXCAVATION
A. General: The trenches shall be excavated to the alignment and
depth as shown on the Plans or as required for the proper installation of
the pipe. The trench shall be braced and/or dewatered, if necessary, in
such manner that the workmen may work therein safely and efficiently.
B. Trench Width: The trench walls in the pipe zone, from the trench
bottom to at least one (1') foot above the top of the pipe, shall be vertical.
The walls of the excavation above this specifically designated pipe zone
shall be substantially vertical. The minimum and maximum width of trench
excavation at the top of the pipe zone, measured one foot above the
top of the pipe, shall conform to the following requirements:
The minimum width of trench shall be the external diameter
of pipe plus fifteen (15") inches.
The maximum width of trench shall be the external diameter of
pipe plus twenty-four (24") inches.
C. Pipe Foundation: The trench shall be excavated to an even grade
to permit the installation of the pipe in such a manner that the full length
of the pipe barrel is supported on the trench bottom.
The entire foundation area in the bottom of all excavations shall
be firm, stable material, and material shall not be disturbed below required
grade except as hereinafter described. Where the character of the foundation
materials is such that a proper foundation cannot be obtained at the eleva-
tion indicated by the plans, then, when directed by the Engineer in writing,
the Contractor shall deepen the excavation to where a satisfactory foundation
can be obtained.
1-1
If the subgrade is soft, spongy, or, disintegrated, the materials
shall be removed until a firm, stable and uniform bearing is reached and the
subgrade brought back to the required grade with material compacted in place
or with granular or concrete embedment material. If the unsatisfactory sub-
grade condition is due to the Contractor's failure to make a proper provision
for adequate drainage of excavations, the expense of replar,ing any unsatis-
factory subgrade shall be borne by the Contractor. Hower?r, if in the
opinion of the Enginear, the unsatisfactory subgrade condition is not the
result of the failure of the Contractor to provide adequate drainage, bailing
or pumping facilities and the Engineer orders in writing that the Contractor
make additional excavation and replace unsatisfactory subgrade material, then
compensation will be made.
0. Correcting Faulty Grade: Any part of the trench excavated below
grade shall be corrected with approved material, thoroughly compacted.
E. Pipe Clearance in Rock: Ledge rock, rock fragments, or unyielding
shale or marT shall e r~ emoved to provide a clearance of at least six (b")
inches below dll parts of the pipe, valves or fittings. Adequate clearance
for properly jointing pipe laid in rock trenches shall be provided at bell
holes.
F. Bell Holes Required: Bell holes of ample dimension shall be dug
in trenches at each joint to permit the jointing to be made properly and so
that the pipe will rest on the roil length of the barrel.
G Depth and Alignment Control: Pipe shall be laid to the grades and
elevations shown on the plans. The Engineer will furnish adequate bench-
marks and reference stakes for the pipe installation. The Contractor shall
set alignment and grade.
The Contractor shall furnish personnel who are skilled in setting
batterboards, and checking grade on both trench excavation and pipe laying.
Substantial batter boards shall be set at intervals close enough so that
when a grade string is pulled across the top the sag will not be more than
1/lb". Batterboards shall be straight. A +ninimum of 3 batterboards shall
be in place at all times.
H. Sheeting and Bracing: This Contractor shall furnish and install
such sheeting, racing, and/or trench jacks as may be necessary to insure
safe working conditions for personnel required to w,,)rk in the bottom of the
trench. It is not the desire of the Owner or the Engineer to assume the
responsibility of deciding what conditions are safe and what conditions are
unsafe. The Contractor is expected to exercise good judgement and due
caution in regard to safety of his personnel. The Engineer reserves the
right, however, to require the Contractor to install trench bracing or re-
sort to other safety measures in cases where, in the Engineer's opinion, a
dangerous situation exists.
1-2
I. DDeewaterin9: This Contractor shall be responsible for the proper
handling of water from any source which may find its way into the trench or
excavations. Any water in the trench where pipe is being laid must be disposed
of in a satisfactory manner so that pipe laying may be done in the dry. Also,
concrete work must be done in the dry. The Contractor shall block storm
drainage from ertering pier excavations, by earth levees or other approved
means.
1.3 STRUCTURAL BACKFILL: Excavated earthen material shall be used for back-
fillingand grading arcund str,:ctures to grades shown on Plans. Backfill
may be placed in three-foot lifts and jttted with water. Pressure jetting
shall continue in eac,l lift of backfill until that lift is completely
saturated.
The equipment for pressure jetting shall be equal to a fire hose having
approximately a five-foot length of 3/4" pipe attached to the end which can
be inserted down into the backfill while large quantities of water are being
forced through under pressure. The source of water should preferably be a
tank truck equipped with a pump for supplying large quantities of water under
pressure. Experience has shown that gravity flow from a tank truck will not
produce the desired results. The jet pipe shall be inserted at close in-
tervals, and sufficient water shall be injected so that the backfill material
will "melt and flow" together, and there will be no bridqing across on dry
areas.
1.4 COMPACTED EMBANKMENT: Prior to plecing any embankment, including excess
earth d s osal, a-lT clearing, grubbing and stripping operations shall be
completed and stump holes or other small excavations shall be hackfilled with
suitable material and thoroughly tamped. Embankment material shall not con-
tain tress, stumps, roots, vegetation, large or frozen lumps, or other extraneous
materials. The surface of the ground, including plowed, loosened ground, or
surface rough?red in any manner, shall be restored to its approximate original

In no case shall the amount of coarse material be such to produce
harshness in placing and hfineycombing in the structure when forms are removed.
In the determination of the amount of water required for mix, considera-
tion shall be given to the moisture content of the aggregate. The net amount
of water in the mix will be the amount added at the mixer; plus the free water
in the aggregate; and minus the abso°ption of the aggregate, based on thirty
(3C) minutes absorption period. No water allowance will be made for evaporation
after batching.
The methods of measure of materials shall be scfch that the proportions
of water to cement can be clsely controlled during the progress of the work
and easily checked at any time by the Engineer or his representative. To
avoiJ unnecessary or haphazard changes in consistency, the aggregates shall be
ob':ained from a source which will insure uniform quality and grading during

can be paddled readily into the corners and nagles of the forms and around
the reinforcing without excessive spading, and without segregation or undue
accumulation of water or laitance on the surface.
5.4 TRIAL MIXES: At least 35 days prior to the beginning of concrete placing,
the Contractor shall submit samples of materials he proposes to use and a
statement of proportions proposed for several concrete mixes, having sufficient
range in slump to cover all placing conditions. The Engineer will require
that laboratory tests be made and such changes as may be necessary to meet the
requirements of the specifications. Laboratory tests on trial mixes shall
show a 28-day strength 15 percent higher than the stated minimum 28-day
strength. From these preliminary tests, the ratios between 7-day and 28-day
strengths shall be established to determine at 7 days the strength necessary
to satisfy the required 28•-day strengths. These ratios shall be modified
as the work progresses as indicated by result of tests on cylinders made
from field mixed concrete.
If,during the progress of the work, it is found impossible to secure
concrete of required workability and strength with the materials being
furnished by the Contractor, the Engineer may order changes in proportions
or materials, or both, necessary to secure the desired properties, subject to
limitations already stated. The Contractor shall not make changes in
materials, either gradation, scarce, or brand, or proportions of the mixture
after their having once been approved except by specific approval of the
Engineer.
