4. PROSECUTION AND PROGRESS
4.01 TIME AND ORDER OF COMPLETION: It is the meaning and intent
of this contract, unless otherwise herein specifically provided,
that the contractor shall be allowed to prosecute his work at
such times and seasons, in such order of precedence, and in such
manner as shall be most conductive to economy of construction;
provided, however, that the order and the time of prosecution
shall be such that the work shall be substantially completed as
a whole and in part, in accordance with this contract, the plans
and specifications, and within the time of completion designated
in the Proposal; provided, also that when the Owner is having
other work done, either by contract or by his own force, the
Engineer may direct the time and manner of constructing the work
done under this contract, so that conflict will be avoided and
the construction of the various works being done for the owner
shall be harmonized.
The Contractor shall submit, at such times as may reasonably be
requested by the Engineer,schedules which shall show the order in
which the Contractor proposed to carry on the work, with dates in
which the Contractor will start the several parts of the work,
and estimated dates of completion of the several pants.
4.02 EXTENSION OF TIME: Should the Contractor be delayed in
the completion of the work by any act or neglect of the owner or
Engineer, or of any employees of elther,or by other contractors
employed by the Caner, or by changes ordered in the work, or by
strikes, lockouts, fires, and unv.sual delays by common carriers,
or unavoidable cause or causes beyond the Contractor's control,
or by any cause which the Engineer shall decide justifies the
delay, then an extension of time shall be allowed for completing
the work, sufficient to compensate for the delay, the amount of
the extension to be determined by the Engineer; provided, however,
that the Co;itractor shall give the Engineer prompt notice in
writing of the cause of such delay.
4.03 HINDI'ANCES AND DELAYS: No claims shall be made by the
Contractor for damages resulting from hindrances or delays from
any cause (except where the work is stopped by order of the owner)
12
I
during the progress of any portion of the work embraced in this
contract. In case said work shall be stopped by the act of the
owner, then such expense as in the judgment of the Engineer is
caused by such stoppage of said work shall be paid by the Owner to
the Contractor.
4.04 LIQUIDATED DAMAGES: The Contractor agrees that time is of
the essence of this contract, and that for each day of delay
beyond the number of days herein agreed upon for the completion
of the work herein specified and contracted for (after due
allowance for such extension of time as is provided for under
Extension of Time hereinabove), the owner may withhold permanently
from the Contractor's total compensation, the sum set forth in
the Special Conditions or Special Provisions (or as elsewhere set
forth in these Contract Documents), as stipulated liquidated
damages for such delay.
5. MEASUREMENT AND PAYMENT
5.01 QUANTITIES AND MEASUREMENTS: No extra or customary measure-
ments of any kind will be allowed, but the actual measured and/or
computed length, area, solid contents, number, and weight only
shall be considered, unless otherwise specifically provided.
5.02 ESTIMATED QUANTITIES: This Agreement, including the
specifications, plans and estimate, is intended to show clearly
all work to be done and material to be furnished hereunder. Where
the estimated quantities are shown for the various classes of
work to be done and material to be furnished under this Contract,
they are approximate and are to be used only as a basis for
estimating the probable cost of the work and.for comparing the
proposals offered for the work. Itis understood and agreed that
the actual amount of work to be done and material 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, payment shall be for the actual amount of such
work done and the material furnished.
Where payment is based on the unit price method, the Contractor
agrees that he will make no claim for damages, 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 estttnated quantities contem-
plated and contained in the proposal; provided, howe-rer, that in
case the actual quantity of any item should become as much as 25%
more than, or 25% less than the estimated cc contemplated quantity
for such items, then either party to this Agreement, upon demand,
shall be entitled to a reviaed consideration upon the portion of
the work above or below 25% of the estimated quantity.
13
Any revised consideration in to be determined by agreement between
the parties, otherwise by the terms of this Agreement, as provided
under "Extra Work".
5.03 PRICE OF WORK: In consideration of the furnishing of all the
necessary labor, equipment and material, and the completion of all
work by the Contractor, and on the completion of all work and of
the delivery of all material embraced in this contract in full
conformity with the specifications and stipulations herein con-
tained, the owner agrees to pay the Contractor the prices set
forth in the Proposal hereto attached, which ha3 been made a part
of this contract. The Contractor hereby agrees to receive such
prices in full for furnishing all material and all labor required
for the aforesaid work, also for all expense incurred by him, and
for well and truly performing the same and the whole thereof in
the manner and according to this Agreement, the attached specifi-
cations and requirements of the Engineer.
5.04 PARTIAL PAYMENTS: On or before the 10th day of each month
the Engineer shall prepare a statement showing as completely as
practicable the total value of the work done by the Contractor up
to and including the last day of the preceding month; said state-
ment shall also include the value of all sound materials delivered
on the site of the work that are to be fabricated into the work.
The Owner shall then pay the Contractor on or before the 15th
4ay of the current month the total amount of the Engineer's
statement, less 10 per cent of the amount thereof, which 10 per
cent shall be retained until final payment, and further less all
previous payments and all further sums ig understood, however,
that in case the whole work be rear to completion and some unexpect-
ed -ni unusual delay occurs dire to no fault or neglect on the part
of the Contractor, the Owner may upon written recommendation of
the Engineer pay a reasonaale and equitable portion of the
retained percentage to the Contractor; or the Contractor, at the
ow-nSr's option, may be relieved of the obligation to fully complete
the work and, th:reupon, the Contractor shall receive payment of
the balance due him under the contract subject only to the condi-
tions stated under "Final Payment".
5.05 USE OF COMPLET'ZD PORTIONS: The Owner shall have the right
to tako possession of and 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.
14
5.06 FINAL COMPLETION AND ACCEPTANCE: Within ten (10) days after
the Contractor has given the Engineer written notice, that the work
has been completed, or substantially completed, the Engineer and
the owner shall inspect the work and within said time, if the
work be found to be completed or substantially completed in accord-
ance with the Contract Documents, the Engineer shall issue to the
Owner and the Contractor his Certificate of Completion, and there-
upon it shall be the duty of the Owner within" the (10) days to
issue a Certificate of Acceptance of the work to the Contractor.
5.07 FINAL PAYMENT: Upon the issuance of the Certificate of
Completion, the Engineer shall proceed to make final measure-
ments and prepare final statement of the value of all wotk per-
formed and materials furnished under the terms of the Agreement
and shall certify same to the Owner, who shall pay to the
Contractor on or after the 30th day, and before the 35th day,
after the date of the Certificate of Completion, the balance due
the Contractor under the terms of this Agreement, provided he
has fully performed his contractual obligations under the terms
of this contract; and said payment shall_ become due in any event
upon said performance by the Contractor. Neither the Certificate
of Acceptance nor the final payment, ncr any provision in the
Contract Documents, shall relieve the Contractor of the obligatio.°
for fulfillment of any warranty which may be required in the
Special Conditions of the Specifications.
5.08 PAYMENTS WITHHELD: The owner may, on account of subse-
quently discovered evidence, Athl*'Id 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.
b. Claims filed or reasonable evidence indicating probable
filing or claims.
c. Failure of the Contractor to make payments properly to
sub-contr9ctors or for material or labor.
d. Damage to another contractor.
When the above grounds are removed, or the Contractor provided
a Surety Bord satisfactory to the Owner, which will protect the
owner in the amount withheld, payment shall be made for amounts
withheld because of them.
5.09 DELAYED PAYMENTS: Should the owner fail to make payment to
the Contractor of the sum named in any partial or final statement,
when payment is due, or should the Engineer fail to issue any
statement on or'before the date above provided, 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
15
provided under "Partial Payments" and Final Payments", until
fully paid, which shall fully liquidate any injury to the Con-
tractor 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", at any
time thereafter to treat the contract as abandoned by the Owner
and recover compensation, 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 EXTRA WORK: It is agreed that the Contractor shall perform
all Extra Work under the direction of the Engineer when presented
with a Written Work Order signed by the Engineer, subject however,
to the right of the Contractor to require a written confirmation
of such Extra Work Order by the Owner. It is also agreed that
the compensation to be paid the Contractor for performing said
Extra Work 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 Mo3thod 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 (15) per cent.
In the event,said Extra Work be performed and paid for under
Method C, then the provisions of this paragraph shall apply and
the "actual field cost" is hereby defined to include the cost of
all workmen, such as foremen, timekeepers, mechanics and laborers,
and materials, supplies, teams, trucks, and rentals on machinery
and equipment, for the time actually employed or used on such
Extra Work, plus actual transportation charges necessarily incurred
tbgeth^r 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,
and on Public Liability and Property Damage, and Workmen's Compen-
sation, and all other insurance as may be required by any law or
ordinance, or directed by the Engineer or 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 may also
specify it writing, before the work commences, the method of doing
the work and the type and kind of machinery and equipment to be
used; otherwise these matters shall be determined by the Contractor.
Unless otherwise agreed upon, the prices for ilia use of machinery
16
and equipment shall be determined by using 100 per ce:n t, unless
otherwise specified, of the latest schedule of Equipment Owner-
ship Expense adopted by the Associated General Contractors of
America. Where practicable the terms and prices for the use of
machenery and equipment 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 expense not
embraced within the "actual field cost" as hereindefined, save
that where the Contractor's Camp or Field Office must be main-
tained primarily on account of such Extra Work; 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 in 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 payment therefor, and the Engineer insists upon its
performance, the Contractor shall proceed with the work after
making written request for written order and shall keep an accurate
account of the "actual field cost" thereof, as provided under
Method C. The Contractor will thereby perserve the right to sub-
mit the matter of payment to arbitration, as hereinbelow provided.
6.02 TIME OF FILING CLAIMS: It is further agreed by both parties
hereto that all questionscf dispute or adjustment presented by
the Contractor shall be in writing and filed with the Engineer
within thirty (30) days after the Engineer has given any directions,
order or instruction to which the Contractor desires to take excep-
tion. The Engineer shall, within a reasonable time, reply to such
written exceptions by the Contractor and render hig final decision
in writing. In case the Contractor should appeal zrom the Engineer's
decision, and demand for arbitration shall be filed with 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 work 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 notad
otherwise in the Contract Documents.
6.03 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 arbiter; 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 thir~ within ten (10) days, he shall be chosen
17
•Y
by a District Judge serving the County in which the majorportion
of the project is located, unless otherwise specified. Should
the party demanding arbitration fail to name 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 information demanded in writing, the arbiters are
empowered by both parties to take ex parte proceedings.
The arbiters shall act with promptness. The decision of any two
shall be binding on both parties to the contract. The decision of
the arbiters upon any question submitted to arbitration under this
contract shall be a condition precedent to any right of legal
action. The decision of the arbiter 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 arbitration
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 and fail or refuse to resume work within ten (10) days
after written notification from the Owner, or the Engineer, or
if the Contractor fails to gdmply with the orders of the Engineer,
when such orders are consistent with the Contract Documents, then,
and in that case, where performance and payment bonds exist, the
Surety on the bonds shall be notified in writing and 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
and payment bonds, or arcther 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 Phall bu allowed as provided for under Section 6, Extra
Work and Claims), it being understood that the use of such equip-
ment anO materials will ultimately reduce the cost to complete
the work and be reflected ih the final settlement.
18
Where there is no performance bond provided or in case the Surety
should fail to commence compliance with the notice for completion
hereinbefore provided for, within ten (10) days after service of
such notice, then the owner may provide for completion of the work
in either of the following elective manners:
7.011 The owner may thereupon, employ such force of men and
use such machinery, 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, and expense so charged shall be de-
ducted and paid by the Owner out of such moneys as may be due, or
that way 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 Con-
tractor 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 shall pay the amount of such
excess to the Owner; or
7.012 The Owner, under sealed bids, after five (5) days
notice published one or more times in a newspaper having general
:irculation 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. In
case of any increase in cost to the Owner under the new contract
as compared to what would have been the cost under this contract,
such increase shall be charged to the Contractor and the Surety
shall be and remain bound therefor. However, should the cost to
complete any such new contract prove to be less than what would
have been the cost to complete under this contract,the Contractor
and/or his Surety shall be credited with the difference.
When the work shall have been substantially completed the Con-
tractor his Surety shall be so notified and Certificates of
Completion and Acceptance, as provided in Paragraph 5.06 herein-
above, shall be issued. A complete itemized statement of the
contract amounts, certified to by the Engineer as being correct,
shall then be prepared and delivered to the Contractor and his
Surety, whereupon the Contractor and/or his Surety, by said
statement, 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 work 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 theta to the owner,
then all machinery, equipment, tools, materials, or supplies left
19
on the site of work shall be turned over to the Contractor and/or
his Surety. Should the, coat to 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 work, notice thereof,,together with an
• itemized list of such equipmentand majetials,"shall be mailed
to the Contractor and his Surety at the respective addresses
designated in this contract; proviO.,dd, however, that actual written
notice given in any manner will Fatisfy this condition. After mail-
ing, or other giving of such nocice, such property shall be held
at the risk of the Contractor and his Surety subject only to the
duty of the Owner to exercise ordinary care to protect such pro-
perty. 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 rrom such sale to the
credit of the Contractor and his Surety. Such sale may be made
at either public or private sales, 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 persona other than the Contractor or his Surety,
to their proper ownere. The books on all operations provided
herein shall be open to the Contractor and his Surety.
7.02 ABANDONMENT BY OWNER: T..n case the owner shall fail to
comply with the terms of this Contract, 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 all machinery,
tools and equipment, and all materials on the site of work that
have not b,ien included in payments to the Contractor and have not
been wrought into the work. And thereupon, the Engineer shall I
make an estimate of the total amount earled by the Contractor, I
which estimate shall include the value o° all work actually com-
pleted by said Contractor (at the prices -ttated in the attached
proposal where unit prices are used), the value of all partially
completed work at a fair and equitable pricey and the amount of
all Extra Work performed at the prices agreed`-upon, or provided
for 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 estimate all previous
payments by the Owner, and all other sums that may be retained by
the Owner under the terms of this Agreement, and shall certify
same to the Owner, who shall pay to the Contractor, on or before
thirty (30) days after the date of the notification by the Contrac-
tor, the balance shown by said final statement as due the Contractor
under the terms of this Agreement.

DENTON, TEXAS
1966 - 1967 STREET ASSESSMENT PROGRAM
DETAIL SPECIFICATIONS
SECTION - 100 GENERAL
100.1 MATERIALS: These specifications are intended ro be so written
that only materials of the beat quality and grade w,li be furnished.
The fact that the specifications may fail to be sufficiently complete
in some detail will not relieve the Contractor of fell responsibility
for providing materials of high quality and protecting them adequately
until incorporation in the project. The specifications for materials
set out the minimum standard of quality which the Owner believes necessary
to procure a satisfactory project. 3o substitutions will be permitted
until the Contractor has received written permission of the Engineer to
make a substitution for the material which has been specified.
100.2 WORKMANSHIP: These specifications contain detail instructions
end descriptions covering the major items of construction and workman-
ship necessary for building and completing the various units or elements
of the project. The specifications are intended to be so written that
only first class workmanship and finish of the best grade and quality
will result. The fact that these specifications may fail to be so
complete as to cover all details will not relieve the Contractor of
full responsibility for providing a completed project of high quality,
first class finish and appearance, and satisfactory for operation, all
within the apparent intent of the plans and specifications.
100.3 HANDLING MATERIALS NOT APPROVED: The Contractor shall remove
from the site any materials found to be damaged, and any materials not
meeting the specifications. These materials shall be removed promptly,
unless the Engineer will accept the materials after repaying. Materials
which are installed and found damaged or not acceptable, shall be removed
and replaced. Inspection before installation shall not relieve the
Contractor from responsibility to furnish good quality materials.
100- l
SECTION 101 - CLEARING AND GRUBBING
101.1 GEARING SITE: Removal and disposal of all existing materials
to tha extent as shown within construction limits on the plans, including
asphalt surface, concrete steps, sidewalk, concrete slabs, culverts,
masonery retaining walls, trees, brush and all other materials not to
be incorporated in the completed work.
101.2 CLEARING: The entire project site shall be cleared of all trees,
stumps, brush, logs, and rubbish except such trees and brush as may be
designated by the Engineer to be left in place. The trees and brush
designated for preservation shall be carefully trimmed as directed and
shall be protected from scarring, barking, or other injuries during
construction operations.
101.3 GRUBBINC: On areas required for construction of embankments, all
stumps, roots, ets., shall be removed to a depth of at least We foot
below the existing ground surface.
On areas required for borrow sites and material sources, stumps, roots,
etc., shall be removed to the complete extent necessary to prevent such
objectionable matter from becoming mixed with the material to be used in
construction.
101.4 CLEANING UP: All materials cleared and grubbed shall be disp,)sed
of, and at the time of final acceptance of the project, the work shall
present a neat appearance, free from all weeds, brush, rubbish, stumps,
and brush.
101.5 MEASUREMENT AND PAYMENT: Clearing and grubbing work will not
be measured for direct payment, but will be considered as subsidiary
work pertaining to the various items of the Contract, and payment
therefore shall be included in Contract unit prices as shown on the
proposal.
101-1
102 - CONSTRUCTION REQUIREMENTS
102.1 PREPARATION FOR PLACING:
EMBANKMENT: Prior to placing any embankment material, the
area upon which it is to be placed shall be scarified or roughened
by plowing to a depth of six (6) inches with furrows in general to
be parallel to existing contours or perpendicular to the natural
slope of the ground. It is essential that the ground be a roughened
condition to provide good bond when the first lift of embankment
is placed.
PLACING EMBANKMENT: The embankment ahall be constructed to
the elevation, lines, grades, and slopes shown on the drawings, as
staked on the ground by the Engineer.
No frozen material shall be pls-ed in any portion of the embankment
nor shall materials be placed cn a frozen surface. No roots, trash,
or debris will be allowed in the embankment. After the subgrade or
base has been prepared as descriiied above, the placing of embankment
material shall proceed as follows!
Upon the wetted subgrade, suitable earthen material shall
be placed in horizontal layers, not to exceed eight (811)
inches in thickness, loose, and leveled by road grades,
bulldozer, or other approved means. Each layer shall be
thoroughly and uniformly wetted to approximately optimum
• moisture content to obtain maximum density in the embank-
ment. Final compaction shall be at least 95% Standard
Proctor. The embankment shall be compacted with a sheeps-
foot type roller, water and/or sand ballasted, having tamping
feet uniformly staggered over its cylindrical surface and
equipped with cleaners. Tamping feet shall be round, dia-
mond, or square shaped with a face area of not less than
five (5) nor more than seven.(7) inches. The roller shall
be capable of exerting a foot pressure of one hundred seventy-
five (175) pounds per square inch of bearing area when ballasted.
Roller as specified by the Texas Highway Department will be
acceptable, provided sufficient ballast is used to obtain the
above specified foot pressure. Other types of rollers capable
of obtaining the desired compaction may be used subject to
the approval of the Engineer.
At places where impossible to roll embankment with roller, material
shall be hand or mechanical tamped until the compaction is equal
to the 95% Proctor Density.
Rolling shall be done on alternate areas, so as to keep the rollers
constantly busy and successive trips or paths of the rollers shall
overlap not less than one (1) foot. The roller shall pass over each
102-1
part of every layer a minimum of eight (8) passes, but in no case
shall the density of the compacted layer be less than 95% of Proctor
Density. One pass shall constitute the passing of one roller in one

SECTION 103 - REINFORCED CONCRETE PIPE
103.1 GENERAL: The work under this item consists of furnishing
all labor, material, and equipment for installation of storm sewer
pipe as shown on the plans and provided in these specifications.
103.2 PIPE: Pipe used in the storm drainage system shall comply
in all respects with the latest requirements of the Standard Speci-
fications for Reinforced Concrete Culvert Pipe, ASTM Designation
C-76-55. The concrete pipe shall be Class III.
Concrete pipe shall be machine made and shall be steam cured in
accordance with ASTM Specification C76057T for a sufficient time to
obtain the required physical strength requirements.
103.3 LAYING CONCRETE TONGUE AND GROOVE JOINT PIPE:
a. Handling: Care shall be exercised in loading, unloading, and hand-
ling the pipe to avoid shock or damage. All material found during the
progress of work to have cracks, flaws, or other defects will be rejected
by the Engineer, and the Contractor shall promptly remove such defective
material from the site of the work.
b. Pipe Laying: The laying of pipes in finished trenches shall
be commenced at the lowest point, so that spigot ends point in the
direction of flow. All pipes shall be laid with ends abbutting and true
to line and grade. :hey shall be fitted and matched so that when laid,
they will form a sewer with a smooth and uniform invert.
c. Jointing the Pipe: All pipe shall be closely jointed
and sealed with stiff mortar, composed of one part portland cement
and two parts sand, so placed as to form a durable watertight joint.
The ends of pipe sb311 be thorm1hly cleaned and wetted before making
the joint. After any section of pipe is laid and before any succeeding
section is laid, the lower half of the bell of the pipe last laid
shall be thoroughly plastered by troweling on at, even layer of mortar.
The spigot end of the next section of pipe shall then be inserted,
holding it as high as possible until it is fully inserted and then lowering
it gently on the mortar. After the section is laid and uniformly matched,
and the sections have been fitted as close as the construction of the
pipe will permit, the lower half of the inner circumfere"ce of the joints
of pipe shall be sealed and packed with mortar and finished smooth and even
with the adjacent sections of pipe. Before this mortar has attained initial
set, additional mortar shall then be applied from the outside and forced
into the unfilled portion of the bell or groove to fill completely the
annular space around the spigot or tongue. For tongue and groove pipe, a
103-1
bead shall be formed extending at least one inch on either side
of the joint and of approximately semi-circular cross-section is
used, it shall be formed by placing the mortar at approximately
45 degrees outward from the extreme edges of the bead. For pipes
too small to permit finish of the inside surface of thq joint, a
tight stopper of burlap or other equivalent materials shall be
dragged through the pipe past the new joint to remove any fins of
mortar.
d. BEDDING: All pipe shall be bedded in a minimum of two (2")
inches of washed pit run gravel, 3/4 inch to 1/4 inch in size.
103.4 INTERFERRENCE WITH EXISTING STRUCT-ORES: In excavating and
backfilling trenches and constructing storm sewers, special care
shall be taken not to remove or injure any existing gas, water,
sewer, or other pipes, conduits or other structures without explicit
instructions of the Engineer. If necessary, the Contractor shall,
at his own expense, sling, shore up and/or otherwise secure and
maintain a continuou3 flow in said structures, and shall repair
any and all damages done to them. In the event a sewer line is
broken o^ damaged in the course of the installation of the storm
sewers, the pipe shall be replaced with cast iron pips of the same
size, which shall extend a minimum of,two (2') feet on each side of
trench excavation. The Contractor stall receive no payment for the
repair of damage caused by the Contractor's operations.
103.5 BACKFI*Z : A granular backfill shall be used aF a backfill
material for all pipe to be located within the curb limits. Good
sound earth say be used as a backfill material for pipe outside
the curb limits of the curb and gutter. The granular backfill shall be
moistened to facilitate compaction and brought up in mechanical tamped
layers not exceeding six (6") inch layers to a point twelve (12") inches
over the top of the pipe. From that point to the surface the pipe may be
backfilled with the granular material and jetted.
103.6 MEASUREMENT AND PAYMENT: Pipe shall be measured from center
of n,anhole or end of pipe without am deductions for the length of
intermediate specials. Fayment will be made at the price bid per
foot for the pipe for the various sizes as set forth in the Proposal.
The bid price shall include all costs for the complete pipe installation
and shall include any and all incidental work not otherwise included in the
bid items or otherwise provided for in these specifications. The price
bid shall include all costs of materials, the cost of clearing and grubbing, the
cost of taking care of conflicts with other utiliteis, the cost of sheeting
or bracing in deep trench, and the cost of all classes of excavation, bedding,
and backfill.

'follow until all clay clods will pass a one inch screen. The subgrade
material shall then be brought to optimum moisture.
104.6 FINAL COMPACTION SHALL BE ACCOMPLISHED in single or multiple lifts,
depending on the equipment used. In either case, the subgrade will be
compacted from the bottom up to at least 95% of Standard Proctor. Moisture
density test will be made continuously during compaction.
104.7 AFTER FINAL COMPACTION has been attained, the subgrade shall be
moistened, if necessary, shaped to final lines, grades, and cross-section,
and shall have a uniform surface, free from compaction planes.
104.8 FOLLOWING FINAL COMPACTION AND SHAPING, the roadway will be closed
to all heav, traffic and allowed to cure for 5 days. At the conclusion
104-1
of the curing period, the flexible base will be laid in the normal
manner.
104.9 The preparation of the subgrade, including lime application, will
be a pay item. This will include all necessary items needed to complete
the job, except the lime which will be a separate pay item. The limits
of the prepared subgrade shall be the entire width of the street extending
six inches back of the curb on both sides, All streets in the program
shall receive lime stabilization, except when specifically exempted by
the Engineer at the time of construction.

the mixer, plus the free water in the aggregate, and minus the
absorption period. No water allowance will be made for evaporation
after batching.
The methods of measure of materials shall be such that the
107-2
proportions of water to cement can be closely controlled during the
progress of the work and easily checked at any time by the Engineer
or his representatives. To avoid unnecessary to haphazard changes
in consistency, the aggregates shall be obtainer: from a source
which will insure uniform quality and grading during any single day's
operatioq and they shall be delivered to the work and handled in
such manner that the variation in moisture content will not inter-
fere with the steady production of concrete of reasonable degree of
uniformity. All sources of supply shall be approved by the Engineer.
The proportions of the mix shall be such as to produce concrete that
can be puddled readily into the corners and angles of the forms and
around the reinforcing without excessive opading, and without segregation
or undue accumulation of water on the surface.

107.6 FORMS: Forms shall be of wood or steel construction and
shall be built mortar-tight and of material sufficient in strength
to prevent bulging between supports and shall be set and maintained
to the lines designated until the concrete is sufficiently hardened
to permit form removal. During the elapsed time between the building
of the forms and the placing of the con:rete, the forma shall be
maintained in a manner to prevent warping and shrinking, All
107-3
details of form construction shall be subject to the approval of
the Engineer, and the permission to place concrete will no,, be
given until all of such work is complete to his satisfaction.
Lumber for forms shall be properly seasoned and of good quality.
It shall be free from loose or unsound knots, knot ~,clcs twists,
shakes, decay and other imperfections which would affect itF strength
or impair the finished surface of the concrete. The lumber used

107.7 PLACING CONCRE M: The Contractor shall give the Engineer
sufficient advance notice before starting to place concrete in any
unit of the structure to permit the inspection of forma, the
reinforcing steel placc,aent, and preparation for pouring. Unless
authorized by the Engineer, no concrete shall be placed in any
unit prior to the completion of the form work and the placement of
the reinforcement.
Whenever it is necessary to continue the mixing, placing and
finishing of concrete after the daylight hours, the site of the
work shall be brilliantly lighted so that all operations are
plainly visible. In general, however, concrete placing shall
be so regulated as to permit finishing operations to to completed
in the daylight hours.
The sequence of placing concrete shall be as provided on tle plans
or in thc, specifications. The operation of depositing and compacting
the concrete shall be conducted so as to form a compact, dense,
impervious mass of uniforms texture which shall show smooth faces
on all surfaces. The placing shall be so regulated that the
pressures caused by the plastic concrete shall not exceed the loads
used in the design of form.
The method and manner of placing shall be such as to avoid the
possibility of segregation or separation of the aggregate or the
displacement of the reinforcement. Concrete shall not have a free
fall of more than eight (8) feet. The spattering of forms or
reinforcement bars shall be prevented if the concrete so spattered
will dry or harden before being incorporated in the mass.
Concrete shall be placed in continuous horizontal layers approxi-
mately 12 inches in thickness. Not more than one hour shall
elapse between the placing of successive layers of concrete in any
portion of the structure included in a continuous placement,
Each part of the forms shall be filled by depositing concrete
directly as nearits final position as possible. The coarse
aggregate shall be worked back from the face and concrete forced under
and around the reinforcing bare and pipe or other inserts without
displacing them. Depositing large quantities at one point in the
forms and running or working it along the forms Will not be allowed.
Foreign matter of any kind shall not be permitted to accumulate inside
the forms, and openings in forms necessary for removal of same shall
be provided.
All concrete shall be well compacted and the motar flushed to the
• surface of the forms by continuous working with concrete spading

implements and mechanical vibrators of an approved type. Vibrators
of the type which operate by attachment to forms or reinforcements
will not be permitted. The vibrators shall be applied to the concrete
immediately after deposit and shall be moved throughout the
mass, thoroughly working the concrete around the reinforcement,
embedded fixtures, and into the corners and angles of the forms
until it has been reduced to a plastic mass. The mechanical vibrator
shall not be operated so that it will penetrate or disturb layers
placed previously which have become partially set or hardened. The
vibrator shall be of sufficient duration to accomplish thorough
compacts,)n and complete embedn„ nt of reinforcement and fixtures but
shall not be done to an extent that will cause segregation. Vibration
shall be suppliemeted by hand spading if necessary to insure the
flushing of mortar to the surface of all forms.
Before the start of placing of concrete, all pipes, conduits,
manhole casting, etc., required to be set in the concrete, shall be
placed into position and firmly anchored.
107.8 FREEZING WEATHER: When depositing concrete at or near freezing
temperatures, the concrete shall have a temperature of at least 50
degrees F., but not more than 120 degrees F. when aggregates are

shall be responsible for the protection of concrete placed under
any and all weather conditions.
107.9 CONSTRUCTION JOINTS: The joint fo nned by placing plastic
concrete in direct contact with concrete that has sttained ito
initial set shall be deemed a construction joint. When concrete in
a structure or a portion of s structure is specified to be placed
monolithic', the term monolithic shall be interpreted to mean that
the manner and sequence of concrete placing shall be such that
construction joints shall have details equivalent to those shown
on the plans for joints in similiar locations.
Unless otherwise provided, construction joints shall be square and
normal to the forms. Bulkheads shall be provided in the forms for
all joints except horizontal joints.
The top surface of a concrete placement which terminates at a
horizontal construction joint shall have surface cement film
removed and shall be thoroughly roughened as soon as practicable
after the concrete has attained initial set. The surface at
• 107-6
bulkheads shall be roughened as soon as the bulkhead forms are
removed. Before. joining plastic concrete to concrete that has
already set, the surface of the concrete in place shall be free
from all loose materials, dirt or foreign matter; shall be wasted
and scrubbed clean with stiff brooms and thoroughly drenched with
water until saturated, and shall be kept wet until the plastic
concrete has beer. placed. Immediately prior to the
placing of additional concrete, all forms shall be drawn tight against
the concrete in place, and the surface of the concrete in place shall
be flushed with a coating of grout mixed in the proportions of one
Fart of cement to two parts of sand.
i
If shown on the plans, construction joints shall be.prov:ded with
cpnerete keyways, reinforcing steel dowels, and/or metal flaW'ng
strips. The method of forming keys in deyed joints shall be such
as to permit the-- removal of iorms without chipping,, breaking,
or damaging the £ot±rrete Tn-dny manner.
107.10 CURING OF CONCRETE: Careful attentions shall be giver. by the
contractor to the proper curing of all concrete in the structures.
All concrete surfacer shall be kept moist by sprinkling or curing
compound for a period of seven (7) days. In cold weather when
curing may be retarded, this aeriod shall be extended as directed
by the Engineer. All uncovered surfaces shall be protected from
deformation or abrasion until thoroughly hardened.
107.11 REMOVAL OF FORMS: Forms for the portion of the structure
• which do not require finish, may be removed in not less than the
number of days set forth in the following table:
forms for walls, columns, and sides of beams 4 days
Forms and falsework under slabs, beams, and girders 7 days
Forms for surfaces required to be fini-hed shall be removed when
the concrete has cged not less than one-half day, nor more than
two' (fj) days.
Test specimens may be made for the determination of time or removal
of forms is cold weather ar.d forms may be removed when test specimens,
cured under like conditions to the curing of the structure,
indicate the required seven (7) day strength has been obtained.
107.12 1INISY.Iu3: As soon as forms are removed, all cavities from
tie holes and "honeycomb", shall be pointed up with 1:2 mortar, and
properly cured so that the patches will not shrink or crack loose.

electrically welded wire mesh fabric, cold drawn mild steal con-
forming to ASTM Designation A185-37.
108.2 BENDING. The reinforcement shall be bent cold to shapes
indicated on t e plans All bending of hard grade and rail-steel
bars shall be done in the shop. Bending of other grades shall
preferably be done in the shop. Buds shall be true to the shapes
indicated, and irregularities in bending for stirrups and ties
shall be made around a pin having a diameter of not less than three
times the minimum thickness of the bar.
168.3 STORING OF STEEL: Steel reinforcement shall be stored above
the surface of the gro,.nd upon platforms, skids, or other supports
and shall be protected as far as practicable from mechanical injury
and surface deterioration caused by exposure to conditions produc-
ing rust. When placed in the work it shall be free from dirt,
scale, rust, dust, paint, oil or other foreign material.
108.4 PLACING AND MAINTAINING REINFORCEMENT: The steel shall be
placed in the forms exactly as shown on the plans. It shall be
maintained in place by wiring, by blocks of "one to two" mortar
properly grooved to hold the bars from lateral displacement, or
by any other effective means approved by the Engineer. In instances
where two or three layers of reinforcement are shown, approved
spacing blocks shall also be placed between each layer, spaced
sufficiently close together to prevent appreciable sag of the bars.
The slab reinforcement shall be raised off the forms by means of
small concrete blocks of mixture as mentioned above and shall be
wired to the longitudinal bars to maintain the proper spacing. It
is very important that the length of bars, spacing and bending
points in same be maintained as shown on the plans. Where splicing
is necessary, the ars shall be lapped at lease 24 bar diameters,
but no bar shall be spliced at points of maximum tension. At all
corners and junctions, the reinforcement must tie together so that
the strength of the junction shall equal the strength of the wall
or member, with bends and laps of at least 24 bar diameters,
108.5 INSPECTION: All reinforcing steel is to be inspected after
placing and approval by the Engineer. Not until this inspection
has been made, and approval obtained, may the pburing of concrete
