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
tha proposals offered for the work. If is understood and agreed that tine
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.
13
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 ind the estimated quantities contem-
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 consideratioa is to be determined by agreement between
the parties, otherwise by the terms of this Agreement, as provided
under "Extra Work".

In the event, said Extra Work be performed and paid for under
Method c, then the provisions of this paragraph shad apply and the
"actual field cost" is hereby defined to include the cost of all
workmen, such as forer,en, timekeepers, mechanics, and laborers, and
mates!tals, 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
together with all power, fuel, lubricants, water, and similar
operating expenses, also all necessary incidental expenses incurred
directly on account of such Extra Work, including Social Security,
Old Age Benefits and other payroll taxes, and a rateable proportion
of premiums on Performance and Payment Bonds, and Maintenance Bonds,
and on Public Liability and Property Damage, and Workmen's Cuzp,u_
cation, and all other insurance as may be required by any law or
ordinance, or directly by the Engineer or Owner, or by them agreed
to. The Engineer may direct the form in which accounto of the
"actual field cost" shall be kept and the rtccrds 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 work and the type and kind of machinery and equipment to be used;
otherwise these matters shall be determined by the Contractor. Unless
r• otherwise agreed upon, the prices for the use of machinery and
equipment shall be determined by using 100 per cent, unless otherwise
specified, of the latest schedule of Equipment Ownership Expense
adapted by the Associated General Contractors of America. Where
practicable the terms and prices for the uee of machinery 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 com;:ensate him for his profit, overhead,
general superintendence, and field office expense, and all other elements

must be maintained 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 to involve Extra Work for
which he should keceive 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
therp'or, and the Engineer insists upon its performance, the Contractor
17
shall proceed with the work after making written request for written
order and shall keep an accurate account of the "actual field cost"
thereof, da 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 appeal from the Engineer's decision,
a demand for arbitration shall be filed with the Engineer and the
Owner in writing within ter. (10) days after the date of delivery
to Contractor of the Engineer's final decision. It is further
agreal 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 noted otherwise in the
Contract Documents.
6.03 ARBITRATION: All questions of dispute under thic Agreement
shall be submitted to arbitration at the request of either party
to the dispute. The parties may agree upon one arbiter; otherwise,

fail to select a third within ten (10) days, he shall be chosen by
s District Judga 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 'ly both parties
to take ex parte proceedings.
The arbiters shall act with promptness. The decision of any two
shalt be binding on both par-ies 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 arbiter, if they deem the case demands it, are authorized to
award ti:e party whose contention is sustained, such sums as they

7. ABANDONMENT OF CONTRACT
7.01 ABANDONMENT BY CONTRACTUR: In case the Contractor should
abandon and fail or reiuse 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 orders of tb° Engineer
when such orders are consistent with the Contract Doriments, then,
and in that case, where performance. and payment bones Exist, the
Surety on the bonds shall be notified in writing afd directed to
complete the work, and a copy of said notice shall be delivered to
the Contractor.
After receiving said notice of abandoorent, 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
material's any 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 i:L completion of the work;
and the Contractor shall not receive any rental or credit therefor
(except when used in connection with Extra Work, where credit shall
be allowed as ;provided for under Section 6, 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 »roviled or in case the Surety
should fail to commence complian_e with the notice for completion
hereinbefore, 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 -nay thereupon employ such force of :aen 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, an6 expense so ~.narized shall be
deducted and paid by the Owner ou' of such moneys as may thereafter
at any time become due to the Contractor under and by virtue of this
Agreement. In case such expense is less than the sum which would
heve been payable under this contract if the same had been completed
by the Contractor, then said Contractor shall receive the difference.
19
In case such expense is greater than the slim which would have been
payable under this contract if the same had been completed by said
Contractor, then the Contractor and/or his Sure!1 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 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 host to the Owner under the new contract as compared
to what would have been the cost under this contract, such increases
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 ehall 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 i.. Paragraph 5.06 bereinabove, shall
be issued. A complete itemized statement of the contract amounts,
certified 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 must pay any amount due tb Owner, as
indicated by said statement, within fifteen (15) days after the date
of such Certificate of Completion.
In tha 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, then all machinery, equipment, tools, materials,
or supplies left on the site of work shall be turned over to the
Contractor and/or his Surety. Should the cost to complete the work
exceed the contract price, and the Contractor and/or his Surety
fail to pay the amount due to the Owner within the time designated
hereittabove, 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 Contractor as 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, Ruch
property shall be held at the risk of the Contractor ,nd his Surety
subject only to the duty of the Owner to exercise ordinary cere to
protect such property. After fifteen (15) days from the date of
20
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 shall release any
machinery, equipment, tools, materials, or supplies, which remain
on the work and belong to persons other than the Contractor or his
Surety, to their proper owners. The books on all operations here-
in shall be open to the Contractor and his Surety.
702 ABANDONMENT BY OWNER: In 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 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 ,rice, 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
can be utilized. The Engineer shall then make a final statement
of the balance due to 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 Agree-
ment, 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 Contractor, the balance shown by said final
statement as due the Contractor under the terms of this
Agreement.

necessary precautions shall-be taken to preserve the material outside
the lines of excavation in the soundest possible condition. Blasting
may be done only to the depth, amount and extent approved by the
Engineer with explosives of such quality, power, and in such locations
as will, in the opinion of the Engineer, neither crack nor damage the
material outside of the prescribed limits of the excavation. Approval
of the methods of blasting by the Engineer will not relieve the Contractor
of his responsibility in blasting operation, and no payment will be
made for any necessary extra excavation below or outside of the limit
lanes indicated on the drawings or modifications thereof directed by
the Engineer, due solely to injury caused by over-shooting, improper
blasting, or carelessness on the part of the Contractor, and all material
thus removed shall be replaced by concrete whey, a concrete structure is

to the Engineer. No blasting shall be done within one hundred (100) feet
of concrete which has been in place less than seven (7) days.
2.04 MEASUREMENTS
An instrument survey of the site of the specified work will be
made by the Engineer prior to commencement of work under this contract,
and all measurements of excavation will be based on this survey as specified
hereinafter, without regard to any natural changes that may occur during
the prosecution of the work. No allowance for unauthorized over-excavation
will be made. Measurement will be as follows:
The volume of Unclassified Structural Excavation will be computed
by the average end area method, using the original ground surface, as
determined by the initial survey, and the excavation limits shown on the
plans or as specifically ordered by the Engineer. In the case of all
structures for which no excavation limits are shown on the plans, the
limit, for pay purposes, shall be taken as a vertical plane one (1')
foot beyond the footing or outside face of the structlire.

SECTION 3
BACKFILL
3.01 DESCRIPTION OF WORK
The work to be performed under this section of the specifications
shall be cc-,nprised of the furnishing of all labor, equipment and materials
necessary to backfill the excavation and to restore disturbed surface
I facilities and cover to a condition as good as that which existed prior
to the start of construction, or better.
3.02 BACKFILL IN STREETS OR PAVED AREAS
Gravel I
The gravel used for backfill in this project shall be a granular,
I sandy gravel, free from clay and organic material and shall be approved
by the Engineer at the source before installation.
Where it is necessary to cut below grade in order to eliminate
a soft or spongy foundation for a structure or conduit, the bottom of
the excavation will be brought back to the correct elevation to place
the embedment called for by backfilling with gravel. The gravel will
i, be placed in uniform layers not exceeding twelve (12") inches in
thickness and compacted to maximum density through the use of pneumatic
or mechanical tamping equipment.
After the conduit or structure is in place and the required
embedment constructed, the excavation will be filled to within twelve
(12") inches of the finish surface grade with gravel, placed and
compacted as indicated in the preceding paragr'r.ph. In the case of pipe
conduits the first backfill layer shall not rise above the spring line
of the pipe, and the gravel shall be' carefully placed to prevent
displacing the pipe or leaving voids in the backfill under the pipe
haunches.
Gravel backfill of conduits will be measured for payment by
the average end area method, using the actual ,epth of excavation

3.03 BACKFILL WITH SELECT MATERIAL FROM EXCAVATION
Outside streets and paved areas, backfill shall be accomplished
using select materials from 6'.9 excavation. The material shall be the
best available from the excavation and shall be free from spongy or
organic material and from unbroken particles larger than four (4") inches
in greatest dimension.
Backfill shall be compacted to a uniform density equal to that
of the adjacent undisturbed earth. bepending upon the nature of the
material, and subject to the approval of the Engineer, compaction of the
backfill may be accomplished by a variation or combination of two general
methods.
(1) Backfill compacted mechanically shall be placed in horizon-
tal layers that can be uniformaly compacted to the required density.
The material in each layer shall contain the amount of moisture required
for optimum compaction, as determined by the Engineer, and the moisture
content shall be as, uniform as practicable throughout the layer. Ad_1acent
to structures and in areas where it is impractical to use roller or tractor,
compaction shall be accomplished with approved power tampers or vibrators.
(2) The backfill may be consolidated by jetting and flooding
when, in the opinion of the Engineer, the material used in backfilling
may be properly consolidated by this means. When this method is employed
to consolidate backfill of the conduit, lift; of backfill shall be
carefully planned to prevent possible damage through flotation of the
conduit and the entire procedure to be followed shall be subject to
prior approval of the Engineer. The flooding shall be accomplished by
pumping water through a pipe which is inserted vertically into the
backfill and lowered slowly to a point clear the bottom of the lift being
consolidated. Pumping shall continue until free water appears at the
surface and no further appreciable absorption of water into the back-
fill occurs.
The Contractor shall have the option of obtaining, at his own
expense from other sources, more easily consolidated backfill materials
than.can be obtained from the project excavations. Whatever the source,
lie shall be permitted to use any method of consolidation which results
in backfill with a uniform density as specified and does not endanger
other parts of the work. ,
Where conduit replaces open ditch or channel, and whether or
not the conduit is placed within such ditch or channel, the ditch or
charnel will be backfilled and maintained in the same manner as specified
for the conduit, so as to eliminate the ditch or channel being replaced
and bring it to the average grade of the surrounding ground.

• Backfill with select materials from the trench excavation will
be considered as incidental to the construction of the conduit and will
not be paid for as a separate item.
Where gravel or concrete is specified for embedment of the
conduit in sections to be backfilleq with select material from the trench
excavation, these materials will be measured by the average end area
me,hod, based on the maximum allowable trench width and the actual depth
of gravel or concrete needed to provide the specified embedment,, Payment
will be at the contract unit price, as privided in the Proposal and Bid
Schedule.
(3) Compacted Earth Embankment'placed for the construction
of the concrete lined channel shall be backfilled in accordance with 3.03
(1) of these specifications. The material shall be palced in 12-inch
horizontal layers and uniforrly compacted to 95% of Standard AASHO
Density with sheepfoot rollers in accordance with the requirements of
AASHO Standard Method T-99-57 at approximately optimum moisture.
3.04 SURFACE REPLACEMENT
(a) Paved Surfaces
No pavement replacement shall be made under this contract.
Where excavation is within a street section, whether paved or unpaved, '
- the gravel backfill shall be brought up to the proposed street elevation.
When required,additional gravel shall be placed adjacent to the
construction to elevate the street the required amount. The adjacent
surface shall be scarified and rolled before the installation of gravel
fill. Additional gravel required from areas adjacent to the excavation
shall be measured and paid for at the bid price per cubic yard compacted
in place. All fill and backfill shall be compacted to 95% Standard AASHO.
(b) Concrete Curb and Gutter
Where the excavation traverses an existing curb and gutter,
the gravel backfill will be continued to the elevation of the bottom of
the existing curb and gutter section, which will be cut back twelve (12")
inches beyond the firm.w8ils of the trench. The curb and gutter will
then be replaced to conform to the section, reinforcing, and finish
of the existing curb and gutter. The length of curb and gutter replace-
ment that will be paid for at each such installation will be the calculated
lt±ngth across the median allowable trench width for the size conduit
installed plus two (21) feet. Payment will be at the contract unit price
per linear foot as listed in the Proposal and Bid Schedule for Concrete
Curb and Cutter.

(c) Unpaved Areas_
In unpaved areas, the backfill will be smoothly mounded
to match the existing ground surface. The top four (4") inches
will consist of a suitable topsoil, either taken from the excavation and
preserved for this purpose or hauled in from another source. No payment
will be made for restoration of surface in unpaved areas.

5.06 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 concrete, the forms shall be maintained in a
manner to prevent warping and shrinking. Ali details of form
corstruction shall be subject to the approval of the Engineer, and the
permission to place.concrote 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
sheeting shall be surfaced on at elast one side dnd two edges and
shall be sized to uniform thickness. Forms shall be suitably anchored
and rigidly braced to prevent movement while placing concrete.
Metal form ties of an approved type shall be used to hold forms
in place. Such ties shall be of a type especially designed for use
in connection with concrete work, and they shall have provision to permit
ease of removal of the metal as hereinafter specified. The use of
wire form ties will not be permitted except for minor special form areas
when the use of rigid type metal ties would be impractical.
The use of metal form ties of type that are encased in paper
or other materials to allow the removal of the complete tie, leaving a
hole through the concrete structure, will not be permitted.
Metal ties shall be held in place by devices attached to walls.
Each device shall be capable of developing the strength of the tie.
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-half
(YO) inch from the surface of the concrete and shall be so constructed
that the rcetal may be removed without undue injury to the surface by
chipping or spelling. Such devises when removed, shall leave a smooth
opening in the concrete surface. Burning off of rods,lbolts, or ties
will not be permitted, Miere wire ties are used, all wires, upon removal
of the forms, shall be cut back at }east one-half (lj") inch from the face
of the concrete with a sharp chisel or nippers.

t .
All cavities produced by the removal of metal ties shall be
carefully cleaned and completely filled with re-tempered sand cement
mortar mix in proportion of one tr, two .*and the concrete shall be
left smooth and even. 41 At the time of placing concrete, the forms shall be clean,
entirely free from all chips, dirt, sawdust, and other extraneous matter.
For wall and other locations where access to the bottom of the forms is
not readily attainable otherwise, adequate clean-out opanings shall be
provided.
5.07 PLACING CONCRETE,
The Contractor shall give the Engineer sufficient slvance notice
before starting to place concrete in any unib,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 any unit prior to the completion of the fora work and the
placement of the reinforcement.
V%enevPr it is necessary to continue the mixins, placing and
finishing of concrete after the daylight hours, the sits 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 be completed in the daylight hours.
The sequence of placing concrete shall be as provided on the
plans or in the specifications. The operation of depositing and
compacting the concrete shall be as t:, form a compact, dgnse, impervious
mass of uniform texture which shall show smooth faces on all surfaces.
The placing shall be so re,.,_lated that the pressures caused by the plastic
concrete shall not exceed the loads used in the design of form.
The method and manner of plating shall'be such as to avoid the
possibility os segregation or separation )f the aggregate or the displace-
ment of the reinforcement. Concrete shall nop have a free fall of more
than eight (8) feet. The splattering of form or reinforcement bars
shall be prevented if the concrete so splattered will dry or harden
before being incorporated in the mass.
f
Concrete" shall be placed in continuous horizontal layers approxi-
mately 12 inches in thickness. No more than one hour shall elapse between
the placing of successive layers of concrete. in any portion of the strucuura
included in a continuous placement.
Each part of the forms shall be filled by depositing concrete
directly as near its final position as possible. 1he coarse aggregate
shall be worked back from the face and concrete,fo.ced under and
around the reinforcing bars and pipe or other inserts without displacing
them. Depositing large quantities at one point in the forms and runniag
or working it along the forms wilt not be allowed.
S-S
Foreign m4tter.leof qny 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 forms by continuous working with concrejc 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 shalt. be moved throughout the mass, thoroughly working
the Concrete around t'he reinforcement, embedded in fixtures, and into the
corners and angles of the forms,until it has been reduced to a plastic
maso, The mechanical vibrator shall not be operated so that it will
penetr"te or disturb layergplaced previously which have- become partially" '
set or hardened. The vibrator shall be of sufficient dutation to accomplish
thorough compaction and complete embedment of reinforcement and fixtures
but shall not be done to an extent that will cause segregation. Vibration
shall be supplimented 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.
5.08. FREEZING WEATHER
When depositing concrete at or near freezin; temperatures, the
concrete shall have a temperature of at least 50 degrees F., but not
more than 120 degrees F. when aggregates are heated. The concrete shall
be maintained at a temperature of at least 50 degrees F. for not less
than 72 bouts after placing, or until the concrete has thoroughly hardened.
When necessary, coAcrete;magrials shall be heated before mixing and
heating apparatus such as stoves, salamanders, etc. shall be supplied to
maintflin the concrete at the required temperature. The Contractor shall
be responsible for the protection of concrete placed under any and all
weather conditions.
5.09 CONSTRUg.TI0.3 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 con-
struction joints shall have details equivalent to those shown on the plans
for joints to aimiliar 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.

horizontal construction point shall have surface cement film removed and
shall be Lhoroiighly roughened as soon as practicable after the concrete
has attained initial.set. The surface at 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 mate*ijls, dirt or fCreign matter;
shall be washed ana scrubbed clean with stiff brooms and thoroughly
drenched with water until saturated, and shall be kept wet unt41 the
plastic concrete-has been placed. Immediately prior to the placing
of additions' concrete, all forms shall ba 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 keyway'; rVin" f?cing steel `dowels, ariVor'4tal flashing
strips. The method of forming ke1-s in keyed joints shall be such
as to permit the easy removal of forms without chipping, breaking, or
damaging the concrete in any manner.
5.10 CURING OF CONCRETE
Careful attention shall be given by the contractor to the
proper curing of all ocncrete'in the structures. All concrete surfaces
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
period shall be extended as directEd by the Engineer. All uncovered
surfaces shall be protected from, deformation'or abrasion until thoroughly
hardened.
5.11 REMOVAL OF FORMS
Forms for the portion of the structure which do not require
finish, may be removed intmobrleos than the number-of days set forth e
