however, that the order And the time of prosecution shall be such
that the work shall be substanially completed as a whole and in
part, in accordance with this contract, the plans and specifications,
and within the times 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 Awner 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 proposes to carry on the work, with dates at
which the Contractor will start the several parts of the work, and
estimated dates of completion of the several parts.
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 either, or by other contractors employed by
the Owner, or by changes ordered in the work, or by strikes, lock
outs, fires, and unusual 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 exten-
sion of time shall be allowed for completing the work, sufficient

determined by the Engineer; provided, however, that the Contractor
shall give the Engineer prompt notice in writing of the cause of
such delay.
4.03 HINDRANCES-AND DELAYS: No claims shall be made by the
Contractor for damages resulting from hindrances and/or delays from
any cause (except where the work is stopped by order of the Owner)

computed length, area,•solid contents, number, and weight only
shall be considered, unless otherwise specifically provided.
5.02 ESTIMATED QUANTITIES: This Agreement, including the specifi-
cations, 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.
It is 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 wokk done and the material furnished.
Where payment is based on the,unit price method, the Contractor
agrees that he villr-"ke no dlaim'for'damages, anticipa;ed-profits
or otherwise on account of vny differences which may be found bet-
ween the quantities of work vtually done, the material actually
furnished under the contract and the estimated quantities cdatem-
plated and contained in the proposal; provided,-however, that in
case the actual quantity of any item should become as much as 25%
more than, or 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.
Any revised consideration is to be determined by agreement between
the parties, otherwise by the turms of this Agreement, as provided
ceder "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

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 day
of the current month the total amount of the Engineer's statement,
less 10 percent of the amount thereof, which 10 percent shall be
retained until final payment, and further less Al It pfevious'payments
and all further sums is understood, however, that in case the whole
work be near to completion and some unexpected and unusual delay
occurs due to no fault or neglect on the part of the Contractor,
the owner may upon written recommendation of the Engineer--pay
a reasonable and equitable portion of the retained percentage to
the Contractor; or the Contractor, at the Owners option, may
be relieved of the 6bligation to fully complete the work and,

• him under the contract subject only to the conditions stated under
"Final Payment".
5.05 USE OF COLLETED PORTIONS: The owner shall have the right to
take 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 coat 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.
5.06 FINAL COLLATION 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

Certificate of Completion, the balance due the Contractor under the
.terms of this Agreement, provided he has fully performed his contrac-
tual obligations under tha terms of this contract; and said payment
shall become due in any event upon said performance by the Contractor.

any provision in the Contract Documents, shall relieve the Contractor
of the obligation for fulfillment of any warranty which may be
required in the Special Condition of the Specifications.
5.08 PAYMENTS WITHHELD: The Owner may, on account of subsequently
discovered evidence, withhold 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.

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

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", 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 'Tartial Payments', at any time thereafter to treat t1,e contract
as abandoned by the Owner sad 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
15
k"4~6 -I
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 agrees 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 coat"
of the work, plus fifteen (15) per cent.
I
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, tears, trucks, and 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 isdidentals dxpensed incurred
directly on account of such Extra 8brk. including Social Security,
Old Age Benefits and other payroll taxes, 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 ardinance,
or directed by the Engineer or Owmr, -oxby them agreed to. The gnginter
may direct the form in which accounts 14 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 in writing, before the work
commences, the method of doing the %.rk 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
fdr'the use of machinery and equipment shall be determined by use of 100
per cent, unless otherwise specified, of the latest schedule of Equip-
ment Ownership Expense adopted by the Associated General Contractors of
America. Where practicable the terms and prices for the use of
machinery and equipment shall be incorporated in the Written Extra Work
Order. The fifteen (15X) percent of the "actual fielA cost" to be paid
the Contractor shall cover and compensate him for his profit, over-
head, 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 maintained primarily on account of such Extra
Work; then the cost to metacain 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,
16
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 sh_11 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 preserve the right to submit 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 questions of 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 exception.
The Engineer shall, within a reasonable time, reply to such written
exceptions by the Contractor and render his final decision in writing.
In case the Contractor should'appeat from the Engineer's decision,
and demand for arbitration shall te 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 ~,)f the final payment shall be a bar
to any claims by either party, except where noted otherwise in the
Contract Documents.
6.03 ARBITRATION: All questions 6f 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 third within ten (10) days, he shall be chosen
by a District Judge serving the County in which the major portion
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 informa-
tion demanded in writing, the arbiters are empowered by both
parties to take ex parts preceedings.
The arbiters shall act with promptness. The decision of any two
say shall be binding on both purti.es 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
17
d
l
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 comply with the others 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 machito ry, 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 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, that where credit shall be
allowed as provided for under Section,69 Extra Work and Claims),
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.
Where there is no performance bond provided or in case the Surety
should fail to commence compliance with the notice of completion
hereinbefoie provided for, within tet. (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 deducted
and paid to 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 Use 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 shall pay the amount of
such excess to the Owner; or
1g
7.012 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. 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'gnd 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 Contractor
and his Surety shall be so notified and Certificates of Completion
and Acceptance, as provided in Paragraph 5.06 hereinabbve, 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 them to the Owner,
then all machinery, equipment, tools, materials, or supplies left
on the site of work shall be turned over to the Contractor and/or
his S•irety. Should the cost to complete the work exceed the con-
tract 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 equipment and materials, shall be mailed to the Con-
tractor and his Surety at the respective addresses designated in
this contract; provided, however, that actual written notice given
in any manner will satisfy this condition. After mailing, or other
giving of such notice, 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 tare 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 made at either public or private
sales, with or without notice, as the Owner may elect. The Owner
I
shall release any machinery, equipment, tools, materials, o. 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 operations
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 CzAtract, and should fail or refuse to comply
with said terms within ten (10) days after written notification by
the Contractor, the*z the Contractor may suspend or wholly abandon
the work, and may Temove therefor from all machinery, tools, and equip-
ment, and all materials on the site of work that have not been
included in payments 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 estimate shall
include the value of all work actually completed by said Contractor
(at the prices stated in the attached proposal where unit prices are
used), the value of all partially completed work at a fair and
equitable price, and the amount of all Extra Work Performed at the
prices agreed upon, or provided for by the terns of this contract,
and a reaslinoble sum to cover the coat 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
es<imate all previous payments by the Owner, and all other sums
than may be retained by the owner under the terms of this Agreement,
and shall certify some to the Ownev, who shall pay to the Contractor,
on or before thirty (30) days after the date of the notification by
the Contractor, the balance shown by said final statement as due the
Contractor under the terms of this sireement.

STREET-IMPROVEMENT PROGRAM
DETAIL SPECIFICATIONS
SECTION - 100 GENERAL
100.1 MATERIALS: These specifications are intended to be so
written that only materials of the best quality and grade will be
furnished. The fact that the specifications may fail to be suffi-
ciently complete in some detail will not relieve the Contractor
of full 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.
No substitutions will be permitted until the Contractor has received
written permission of the Engineer to make a substitution for the
materials which has been specified.
100.2 WORKYANSHIP: These specifications contain detail instruc-
tions and descriptions covering the major items of construction and
workmanship necessary for building and completing the various units
of elements of the project. The specifications are intended to be
best so written that only first class workmanship and finish of the
best grade and quality will result. The fact that these specifica-
tions 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 sat-
isfactory 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 shall be taken off the site. These
materials shall be removed promptly, unless the Engineer will
accept the materials after repairing. 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,

SECTION 101 - CLEARING AND GRUBBING
101,1 CLEARING SITE: Removal and disposal of all existing materials
to the extent as shown within construction limits on the plans,
including asphalt surface, concrete steps, dfivewayp,•approachai,
culverts, masonry retaining walls, trees, brush and all other materials
not to be incorporated in the completed work.
101.2 CIBARING: 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 treeg
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 GRUBBING: On areas required for construction of embankments,
all stumps, roots, etc., shall be removed to a depth of at least
one 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
disposed of, and at the time of final acceptance of the project,

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 ANT: The embankment shall be constructed to
the elevation, lines, grades, and slopes shown on the drawings, and
as staked on the ground by the Engineer.
No frozen material shall be placed in any portion of the embankment
nor shall materials be placed on a frozen surface. No roots, trash,
or debris will be allowed in the embankment. After the subgrade or
base has been prepared as described 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 (8) inches
in thickness, loose, and leveled by road grader, bulldozer,
or other approved means. Each layer .hall be thoroughly
and uniformly wetted to approximately optimum moisture content
to obtain maximum density iu the embankment. The embankment
shall be compacted with a sheepsfoot tynn roller, water and/or
sand ballasted, having tamping feet unitormly staggered over
its cylindrical surface and equipped with cleaners. Tamping
feet shall be round, diamond, 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 abov, specified foot pressure.
Other types of rollers capable of obtaining the desired com-
paction may be used subject to the approval of the Engineer.
At placed 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
over lap not less than one (1) foot. The roller shall pass over each
102-1
i
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 (1) pass shall constitute the passing of one (1)
roller in one (1) direction over any area with one (1) overlap over the
path of the preceedit,6 roller.

In determination of the amount of water required for the mix,
consideration shall be given to the moisture content of the aggregate.
The net amount of water in the mix will be of the amount added at
the mixer, plus the free water in the a,&Sregate, and minus the
absorption of the aggregate, based on thirty minute absorption
period. No water allowance will be made for evaporation after
batching.
The methods of measure of materials shall be buch that the
107-2
proportions of water to cement can be closely controlled during the
progress of tha work and easily checked at any time by the Engineer
or his represenkatives. To avoid unnecessary to haphazard changes
in consistence, the aggregates shall be obtained from a source
which will insure uniform qualii.y and grading during any single day's
operation 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 s4zh as to produce concrete that
can be puddled readily into the corners and angles of the forms and
around the reinforcing without excessive spading, and without segre-

of equipment he proposes to use, the adequacy of which shall be
subject to the approval of the Engineer.
Before constructing forms, the Contractor shall submit to the Engineer
for his approval detail information, including necessary drawings and
sketches of proposed forp works, which shall be sufficiently complete
to show all essential details.
Concurrence on the part of the Engineer in any proposed construction
methods, approval of equi meat, or approval of forms shall not be
considered as relieving tie Contractor of the responsibility for the
safety or correctness of his methods and adequacy rif this equipment
safety or from carrying out the work in full accurdance with contract.
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 biapsed time between the build-
ing of the forms and the placing of the concrete, the forms shall
be maintained in a manner to prevent warping and shrinking. All
107-3
dFtails of form construction shall be subject to the approval of
ffe Engineer, and the permission to place concrete will not 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 holes, twists,
shakes, decay and other imperfections which would affect its strength
or impair the finished surface of the concrete. The lumber
used for facing or cheating shall be surfaced on at least one side

Pipe spreaders will not be permitted.
All metal appliances used inside of forms to hold them in correct
alignment shall be removed to a depth of at least one-hal,f (J)
inch from the surface of the concrete and shall be so constructed
that the metal may be removed without undue injury to the surface
by chipping or opalling. Such devices when removed, shall leave
a smooth opening in the concrete surface. Burning off of rods, bolts,
or ties will not be permitted. Where wire ties are used, all wires
upon removal of the forms, shall be cut back at least one-half (k)
inch from the fame of the concrete with a sharp cLisel or nippers.
All cavities produced by the removal of metal ties shall be care-
fully cleaned and completely filled with re-tempered sand cement

107.7 PLACING CONCREIZ: 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 forms, the
reinforcing steel placement- and preparation-for pouring. Unless
authorized by the Engineer, no concrete shall be placed in r.ny
unit prior to the completion of the formwork 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 shi.11 be brilliantly lighted so that all operations are
plainly visible. Ia general, however, concrete placing shall
be so regulated as to permit finishing operations to be completed.,
in daylight hours.
The sequence of placing concrete shall be as provided on the Plans
or in the Specifications. The operation of depositing and compact-
ing 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 forms.
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 (R) feet. The spattering of forms or
reinforcement bars shall be presented 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 por-
tion of the structure included in a continuous placement.
Each part of the forms shall be filled by depositing concrete
directly as near its final position as possible. The coarse aggre-
gate shall be w^ rked back from the face and concrete forced under
and around the reinforcing bars and pipe or other inserts without
displacing them. repositing large quantities at one point in the
forms and running or working it along the forms will not be allowed.
Laitance or 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 mortar flushed to
the surface of the Corms by continuous working with concrete spading
107-5
implements and mechanical vibrators of an approved type. Vibrators of
the type whic~N operate by attachment to forms or reinforcements
will not be permitted. The vibrators shall be applied to the con-
crete immediately after deposit and shall be moved throughout the
mass, thoroughly working the concrete around the reinforcement,
embodded 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 operaced so that it will penetrate or disturb lavzrs i
placed previously yhich have become partially set or hardened. The
vibrator shall be of sufficient duration to accomplish thorough
compaction and complete embedment of reinforcement aLd fixtures but
shall not be done to an extent that will cause segregation. Vibra-
tion shall be supplemented by hand spading if necessary to insure
the flushing of mortar to the surface of all forma.
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 aggre-
gates are heated. The concrete swill be maintained at a tempera-
ture of at least 50 degrees F. for not less than 72 hours after
placing, or Until the concrete has thoroughly hardened. When necessary,
concrete materials shall be heated before mixing and heating appar-
atus such as stoves, salamanders, etc. shall be supplied to maintain
the concrete at the required temperature. The Contractor shall be
responsible for the protection of concrete placed under any and all
weather conditions.
107.9 CONSTRUCTION JOINTS: The joint formed by placing plastic
concrete in direct contact with concrete that has attained its
initial set shall be deemed a construction joint. When concrete
in a structure or a portion of a 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 will not occur. Additional joints shall not
be provided without written authorization from the engineer. Any
additional construction joints shall have details equivalent to
those shown on the plans for joints in similar 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 re-
moved 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, laitance, dirt or foreign matter; shall
be washed and scrubbed clean with stiff brooms and thoroughly
drenched with watt. until saturated, and shall be kept wet until
the plastic concrete' has been 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 part of cement to two parts of sand.
If shown on the plans, construction joints shall be provided with
concrete keyways, reinforcing steel dowels, and/or metal flashing
strips. The method of forming keys in dryed joints shall be such
as to permit the easy removal of forma without Aping, breaking,
or damaging the concrete in any manner.
107.10 CURING OF CONCRXTj: Careful attentions shall be given by the
Contractor to the proper curing of all concrete in the structures.

in all respects with the latest requirements of the Standard
Specifications of Reinforced Concrete Culvert Pipe. ASTM Designa-
tion C-76-55, and Item 460 entitled Corrugated Galvanized Metal Pipe of
the Texas Highway Department 1962, Standard Specifications for Road
and Bridge Construction. The concrete pipe shall be Class 111.
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.
114.3 LAYING CONCRETE TONGUE AND GROOVE JOINT PIPE:
a. Handling: Care shall be exercised in loading, unload-
ing and handling 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.
h. Pipe Laying: The laying of pipes in finished trenches
shall be commencer) 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. They shall be fitted and matched
so that when laid, they will form a sewer with a smooth and uniform
invert. No pipe shall be laid when the trench ind weather conditions
make it impractical to do so.
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 shall be thoroughly cleaned and wetted before
making the ,joint. After any section of pipe is laid and before
any r.,icceed£ng section is laid, the lower half of the bell of the
pipe :ast laid shall be thoroughly plastered by troweling on an
even '.ayer 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 circumference of the joints of pipe
over eighteen (18) inches in diameter shall be sealed and packed
with mortar and finished smooth and even with the ,idjacent 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
114-1
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 the 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. Foundation: All ¢ipe shall be bedded in a foundation
of stable earth material carefully and accurately shaped to fit
the lower part of the pipe extension for at least twenty per cent
,of its overall height. Where rock, in either ledge or boulder
formation is encountered, it shall be removed below grade and
replaced with suitable materials in such manner as to provide a
compaeltad earth cushion having a thickness under the pipe of not
less than one-half inch per foot height or fill over the top of
the pipe, with the minimum allowable thickness of eight (8) inches.
114.4 IW. SRFSRSNCS WITH RXISTING STRUCTURES: In excavating and
backfilling trenches and constructing storm sewers, special care
must be taken not to remove or injure any e;isting gas, water,
sewer, or other pipes, conduits or other structures without explicit
instructions of the Sagineer. If necessary, the Contractor shall,
at his own expense, sling, shore up and/or other wise secure and
maintain a continuous flow in said structures, and shall repair any
and all damages done to them. In the event a sewer line is broken or
damaged in the course of the installation rs the storm sewers, the
pipe shall be replaced with cast iron pipe of the same size, which
shall extend a minimum of two (2) feet on each side of the trench
excavation.
114.5 BACKFILL: A granular backfill shall be used as a bsckf!ll material
for all pipe to be located within the curb limits. Good sound .ar:h
may 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 maybe back-
filled with the granular material and jelled.
114.6 MEASUREMENT AND AYMSNT: Pipe will be measured from center
of manhole to center of manhole or and of pipe without any deductions
for the length of intermediate specials. Payment 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 shell include all costs for

SECTION 116 - CHANNEL PAVING
116.1 GENERAL: This item shall govern the channel paving work required
at the Extension of the culvert on Oakland Street and the channel paving
required at the intersection of McCormick and Willowwood,
`116.2 CHANNEL PAVING: The surfaces on which this paving is to be
placed shall be graded smooth and uniform to conform with the sections
shown in the Plans. The pipe inserts and gravel for the drainage
system, as hereinafter described, shall be placed in accordance with
the Plans. The reinforcing steel shall be placed as shown on the Plans
and shall comply with the applicable section of these Specifications.
Concrete shall have a compressive strength of 2500 p.s.i. Transverse
expansion joints shall be provided at intervals shown on the Plans,
with reinforcing discontinued through these joints.
Before pouring concrete, temporary screed boards shall be set
approximately 13 ft, apart, and to the proper elevation so that the
concrete can be uniformly screeded off to a uniform 5" thickness. The
screed boards shall be supported on stakes which are dtLven deep enough,
and are strong enough to furnish adequate support. As the concrete is
poured, and screeded off these stakes shall be pulled and shall not be
left in the concrete. Other methods for providing "screed off" points
will be considered, but the Engineer will insist on adequate screed
controls.
Concrete for this paving, and especially that on the slopes will
need to be fairly dry mix with low slump, After the concrete is placed,
it shall first be vibrated, paddled, and worked down to eliminate voids.
After screeding, it shall be lightly floated with a wood float to obtain
a reasonably smooth surface. Immediately before placing concrete, the
subgrade to receive concrete shall be dampened to prevent too rapid absorp-
tion of moisture from the concrete. Precautions shall be taken to avoid
penetrating the gravel in the drainage system with mortar from the concrete;
if necessary, kraft paper or other suitable membrane material shall be
used to keep mortar out of the gravel.
All channel paving shall be done "in the dry", and, if it becomes,
necessary to protect the work area from the dry-weather flow in the channel,
the Contractor shall provide suitable cofferdams or other means to
accomplish this protection. All freshly-poured concrete shall be protected
from the atream flow for a period of 36 hours or for a period which is
deemed adequate, in the opinion of the Engineer, for the concrete to
attain sufficient strength to sustain the action of flowing water without
damage to the finished surface.
116.3 DRAINAGE SYSTEM: A drainage system, consisting of a gravel-filled
drain and pipe inserts extending through the concrete paving for weep
holes, shall be cAnatructed at the too of all side-slope paving as shown
in the Plans.
116-1
Gravel for the drainage system shall comply with requirements for
Coarse Aggregate for Concrete, as herein specified, except the grading
requir/..ants shall be as follows:
Sieve Size Percent Passing
2" 100
lk" 90 to 100
1" 20 to 55
3/4" 0 to 15
3/8" 0 to 5
Pipe inserts for the weep holes shall be 2-inch inside diameter
iron pipe and shall be placed as shown in the Plans. In placing these
pipe inserts, care should be taken to provide a slight slope through
the pipes to allow complete drainage of the pipes into the channel.
116.4 MAINTENANCE OF CHANNEL PAVING All concrete paving shall be
maintained in a satisfactory conlition throughout the period of
construction of this project and until acceptance by the City of Denton.
Any damage to the concrete paving shall be suitably repaired and the
• entire surface shall be Rept free from accumulations of track, debris or
other objectionable deposits until acceptance of the project.
116.5 The concrete channel paving on McCormick Street will be paid
for at the unit price bid per dquare yard of surface area of concrete
in place. The concrete channel paving on Oakland Street shall be
included in the lump sum bid for the construction of the Box Culvert
