construction and 20 ft. wide permanent easement . In such cases where
the Contractor may desire to occupy space outside the 60 ft. width, or
where ingress end egress is desired at intermediate points , the Con-
tractor shall make his own arrangements with the land owner. The Con- '
tractor shall take all reasonable precautions to protect adjacent land,
structures , trees, fences on the easement or adjacent land , and may be
responsible to save the Owner harmless from damage claims which may
result from his operations. The same reouirements shall apply when the
sewer line is located in City Streets or public highways.

16. PROTECTION OF PROPERTY AND EXISTING UTILITIES: Within developed
areas,,aTl ilr vate property along and adjacent to the Contractor' s
operations , including lawns , yards, shrubs and trees, shall be ade-
quately protected, and when damaged or removed, shall be repaired,
replaced, or renewed or otherwise put in a condition equal to or better
than that which existed before the Contractor causeo the damage or
removal .
An attempt has been made to show existing utilities on the plans , but
the possibility remains that some underground utilities may exist that
have not been shown. The Contractor, through contact with local utility
owners, shall keep himself informed and take such precautions as neces-
sary to avoid damage.
If an existing utility is in conflict with the proposed sewer line, the
Owner will either move the sewer line or have the utility moved at the
Owner' s expense. Where the Contactor desires to have an existing
utility moved that does not actually conflict, but is adjacent to the
Contractor' s work, then in such case the Contractor shall pay for ad-
justment of the existing utility.
17. CHANGE IN LOCATION: No change in the alignment is contemplated;
however , should a change be necessary, the Owner reserves the right to
make such changes, and unless it can be clearly shown that such change
works aii undue hardship on the Contractor, no extra compensation will be
allowed.
18. WATER FOR CONSTRUCTION. The Contractor may purchase water as
required for construct on purposes at the City' s published rate of
charge through existing fire hydrants. If the Contractor desires to
take water at fire hydrants, then he shall install at his expense, a
Slow closing valve on the outlet and a suitable metor. When the Con-
tractor is using water from the hydrant, he shall open the hydrant valve
in the corning and use the valve which he has installed for control at
all other times. At night , upon cessation of construction operations ,
the hydrant valve shall be closed. At all times when the Contractor' s
valve remains on the outlet, .,ie Contractor shall keep necessary wrenches
available at the hydrant .;o that the valve can be quickly removed by the
City in case of fire. The City will not be required to furnish water
unless the Contractor adheres to the above described requirements.
19. MATERIALS FURNISHED BY OWNER: The Owner will not furnish any
materM? 'T
20. CLASSIFICATION OF EXCAVATION: All excavation for this project will

instances an excess of material over that required to bring the backfill
up to the original grade. In such cases where there is an excess of
material , this Contractor shall load and haul it away from the job site
and dispose of it in a manner acceptable to the City.
23. MEASUREMENT AND PAYMENT: A11 work and material in this contract is
to be paid for through monthly estimates prepared by the Contractor and

document.
24. PROJECT SIGNS: Two project identific6tion signs are required as a
part of Contract "A" and one sign for Contract "B". The signs shall be
produced in accordance with the details shown in the Federal Specifi-
cations (pink sheets) which are bound into this document. The signs
shall be erected on a prominent street near construction areas. No
direct payment will be made for these signs , but the cost shall be
subsidiary to the bid items included in the proposal .
25. LOCAL MATERIALS AND LABOR: The Contractor shall give preference to
the use of local materials , or the use of materials which may be avail-
able through local suppliers , when the cost or quality of such materials
are equivalent to those obtained elsewhere. The Contractor shall also
- give preference to the employment of local citizens insofar as they are
available and suitable for the work to be done.
26. PROGRESS SCHEDULE: Prior to beginning work, the Contractor shall
furnish t e nq n� eer with an anticirated progress schedule covering all
of the work to be performed under this contract. During construction,
the schedule shall be revised to reflect as nearly as possible the
actual construction operations. The Contractor shall also furnish the

items of equipment and material . These fates shall be keyed to the
progress schedule for the work.
27. NOTICE OF REQUIREMENT FOR CERTIFICATION OF NONSEGREGATED FACILITIES:
Bidders are cautioned as follows: By signing the contract for wh cr h
these bids are solicited, the bidder will be deemed to have signed and
agreed to the provisions of the "Certification of Nonsegregated Facili-
ties" as contained in the Specifications for this project.

A certification of Nonsegregated Facilities , as required by the May 8,
1968, order (33 F. R. 7808, May 280 1968) on Elimination of Segregated
Facilities , by the Secretary of Labor, must be sbumitted prior to the
B-5
award of a federally assisted construction contract exceeding $10,000
which is not exempt from the provisions of the Equal Opportunity Clause.
Contractors receiving federally assisted construction contract awards
exceeding $10,000 which are not exempt from the provisions of the Equal
Opportunity Clause will be required to provide for the forwarding of
contracts where the subcontracts exceed $10, 000 and are not exempt from
the provisions of the Equal Opportunity Clause.
29. EROSION AND SEDIMENT CONTROL MEASURES: The Contractor is expected
to conduct h s work in such a manner as to minimize any soil erosion or
sediment runoff from the construction site, Ear-th cuts and fills shall
have smooth, flat sideslopes, as generally indicated on the plans , to
preclude erosion of the soil . Such operations should be timed consistent
with the actual need for doing the work and to leave raw, unprotected
surfaces a minimum period of time.
Existing bermuda grass lawns are to remain intact as far as practical .
Such areas as are disturbed shall be duly restored by the Contractor and
he shall be responsible for correcting any erosion that occurs.
As construction progresses and at locations where erosion with sediment
runoff occurs or is likely to occur the Contractor shall construct
temporary ditches, retainage levees , drains , inlets, or other works to
correct the condition. Upon completion of the work such facilities
shall be removed.
The plans show all planting areas, turf areas and rock fill areas all of
which in their complete form will be stable, protected, non-erosion
surfaces. During construction the Contractor shall take the necessary
precautions to see that erosion is controlled and sediment runoff is
prevented.
30. PUMP STATION STRUCTURE - FLOATATION PREVENTION: When the concrete
Pump stat on structure s empty no water on ns e), the buoyancy force
of water on the outside, if completely filled around the structure would
be greater than the weight of the structure. For this reason, care must
be exercised that the structure is not floated up from its intended
grade. This Contractor shall assume responsibility to insure that the
structure remains on grade until completely backfilled. The Contractor
is especially reminded to avoid surface or ground rater filling the
excavation around an empty structure. Also, the brttfm five ft. of
backfill shall be compacted in lifts not more than 8" loose measure. No
Jetting shall be done in the lower 5 ft. of backfill.
31. LIMITS OF PUMP STATION CONTRACT "E " : The pump station shall begin
with a fl ange connection to the 2� orce main at Station 301+96 and
continue to a final connection with the 27" Hickory Creek Interceptor at
Station 3D2+18 as shown on the plans. The lump sum price bid for the
Pump station shall be inclusive of all excavation, formwork, concrete,
steel , necessary, finishes,
foranopra operable d fence
ionatcompletionn on the plans

in uniform layers. The method of compaction and the equipment used
shall be appropriate for the material to be compacted and shall not
transmit damaging shocks to the pip:. Job excavated material shall be
compacted to 95 percent of maximum density at optimum moisture content
As determined by ASTM 698.
Compacted backfill for use under paved roads shall consist of the
"Granular Embedment" material previously described herein.
b. Uncompacted Backfill : Earth backfill material to be placed
above pipe zone shall be free of brush, roots more than 2 inches in
diameter, debris , and funk, but may contain rubble, rock, stones, and
boulders, in certain portions of the trench depth.
Uncompacted backfill material above pipe zone may be placed by any
method acceptable to the Engineer, which will not impose excessive
concentrated or unbalanced loads, shock, or impact on, and which will
not result in displacement ,of, installed pipe.
Compact masses of stiff clay or other consolidated material more than
one cubic foot 'in volume shall Got be permitted to fall more ,than 5 feet
into the trench dnless 'cushioned by at least 2 feat of loose backfill
above ',pipe zone.
No u6o'lmpatted trench' backfill material containing large rocks shall be
placed in the upper ]8 :inches of the tr,engt except with specific Per-
Mission of th`e Engineer, nor shall any stone. ,l,arger then 8 ,inches in its
greatest dimension be placed within 3 feet of the top of pipe. Large
s ones may be plated in the remainder of ,the, trench backfill only if
W 11 'bb�'ared and 'so arronged that no interference with, backfill,+ ,
settlement ill result.' 41 1
C. Compacte,d ,Sackfill_ Methods: All of, the backfill material
shall ae c9mpacted and the Contrac4tor, at his . discr0 ion, . leay use either
the' pneumatic camp' method in 0 lifts or pressure ,jetting with water, as
herein described. If the jettingg; pethod is,used, the, first lift shall
not excsed 4 feet and shall be thoroughly jetted before any more back-
fill is placed. Pressure. Jettiny Shall poptinue in ; each lift of backfill
until that lift is completely saturated.
the equipment for pressur'e' jett3ng shall po equal to a fire hose having
a length of 3/4" pipe attached to the end which can be inserted down
into the backfill while,,%Qq quantitjRs ;of yatar , are being forced
through under pressu�"e'. a source of water should preferably be a tank
truck equippeq with a pump fpr ,supplyi,ng ,la,rga ,quantities ;of water under
p)"ess re., , Expph ehce has shpwp .that gravl W flow from;a U nk :truck ,will
not 'd oduce the esired results. The jet piPe s,hallbe inserted at 6'
maximum intervals , and sufficient water shall be injected so that the
backfill material will "melt pd flow": and there will be no
bi'ldgirig across or, dry area,. . ; � ;
28.8 ,
Care shall be exercised in jetting the first lift to insure that the
backfill material is thoroughly consolidated around the pipe without
floating the pipe up from its proper grade. The Contractor shall
correct any pine which has been floated up from grade.
Where the tamping method of backfill is used the material shall be
placed in lifts not to exceed 8" depth , wetted to approximately optimum
moisture content, and compacted with pneumatic , vibratory or other
approved mechanical tamps. Additional lifts shall not be placed until
the lift being compacted has attained a density of at least 95% of
standard Proctor density.
It is the intent of these specifications that, by good backfill pro-
cedure, the backfill will be of such density as to preclude after -'
settlement. This Contractor, upon request, shall refill or repair any
trench areas which may settle within one year after final acceptance of
the project.
Backfill around manholes and sewer line structures shall be done in a
similar manner to thrt described above for backfill of pipe trenches and
may be accomplished simultaneously therewith.
d. 1lntompacted Backfill Methods: In large, cattle range, open

inside wall of the manhole and shall be drilled and tapped for bolting
on the blind flange with stud bolts. Remove bolts after satisfactory
tests.
Care shall be used to see that all air vents are open during the filling.
After the line , or section thereof, has been completely filled, it shall
be allowed to stand under a slight pressure at least 24 hours to allow
the pipe to absorb what water it will and to allow the excape of air
from any air, pockets. During this period, the plugs, valves, manholes,
and connections shall be examined for leaks. If any are found, these
shall be stopped, or in thv case of plugs in the main line, provision
shall be made for measuring the leakage during the test, The water
necessary to maintain tha .test pressure shall be measured through a
mete r, or. y oi;her means satisfactory to, the Owner, . Contractor shall

A. GENERAL
ACI 211 . 1 shall be the basis for selecting the proportions for
concrete made with aggregates of normal and high density and of
workability suitable for usual cast-in-place structures.
B. PROCEDURE IN DESIGN OF CONCRETE MIXES
I . General : The Contractor shall be responsible for the
design of the concrete consistent with the minimum re-
quirements of strength and proportions stated herein.
The proportions of materials entering into the mix,
subject to limitations already stated, to produce con-
crete of satisfactory quality, shall be determined by
laboratory tests prior' to beginning of concrete placing.

3. Changes in Mixes: If, during the progress of the work,
it is found impossible to secure concrete of required
workability and strength with the materials being fur-
nished by the Contractor, the Engineer may order changes
in proportions or materials or both, necessary to secure
the desired properties, subject to limitations already
stated. The Contractor may not make changes in materials,
,
either gradation, source, or brand, or proportions of
mixtures after their having once been approved except by
specific written approval of the Engineer.
C. WORKABILITY
In gener-s ! the workability of any mix shall be that required
for the specific placing conditions and method of placement.
The concrete shall be of such workability that it can be
worked readily into all corners and around reinforcing without
segregation of materials or having free water collect on the
surface. Compliance with specified slump limitations shall
not necessarily designate a satisfactory mix. The Engineer
mmay, require changes in proportions at any time as necessary to
obtain a mix ,hav,iing satisfactory propper n es. The slump tests
will be made by, the Engineer' (or a, designated representative
of the Owner' s laboratory) in accordance with ASTM Method of
Test for Slump of ,Portland Cement,Concrete, ,Designation C-143.
In no case shall the amount of coarse material be such as to
produce harshness in placing or honeycombing in, the structure
when forms are removed.

The maximum amount of water as set forth in the table above is
based on the assumption that the aggregates are in a saturated ,
surface dry condition.
The maximum water content will be the amount added at the
mixer, plus the free water in the aggregate , and minus the
absorption of the aggregate based on a thirty-minute absorp-
tion period. No allowance will be made for evaporation of
water after batching. If additional water is required to
obtain the desired slump, a compensating amount of cement
shall also be added. The maximum water-cement ratio shall not
be exceeded. No additional compensation will be made for
additional cement which may be used under this condition.
The concrete mix will be designed with the intention of pro-
ducing concrete which will have compressive or flexural strength
equal to or greater than the following when using current ASTM
Designation C-39 and C-293:

F. TESTS OF CONCRETE
1 . General : Frequent tests will be required by the Engineer
throughout the work to determine the quality of concrete.
Unless otherwise specified these tests shall be made by
an independent testing laboratory to be selected and paid
for by the Contractor. All samples shall be taken in
accordance with ASTM C172.
2. Slump Test: The slump test as described in ASTM C143
will be used to indicate workability and consistency of
the concrete mix from batch to batch. Generally, a slump
test will be made at the start of operations each day, at
regular intervals throughout a working day, and at any
time when the appearance of the concrete suggests a
change in uniformity.
3. Air Content Test: Tests for air content of the concrete
shall be made in accordance with ASTM C231 , at the pnint
of delivery of concrete dust prior to placing in forms.
The test shall be made often enough to insure a proper
air content uniform from batch t4 batch.
4,. COMP ression Test: Compre'ssi,on test specimens shall be 6"

Compression strength tests shall be made on the labora-
tory cured and ,fob cured concrete cylinders at 7 and 28
days, in accordance with ASTM C39, latest designation.
The value of each test result shall be the average com-
pressive strength of two samples taken at the same time
from the same batch of concrete. The tests made at 7
days shall show strengths of not less than two-thirds
(213) of the design strength. For the 28 day cylinders ,
the strength level will be considered satisfactory if the
averages of all sets of three consecutive strength test
results exceeds the required design compressive strength,
ft , and no individual strength test result falls below
the required ft, by more than 500 psi .
If the test record of the standard-cured specimens fails
to satisfy the strength requirements , the Engineer shall
have the right to order a change in the mix proportions.
If the job-cured cylinders fail the str( oigth criteria,
the Engineer shall have the right to require changes in
temperature, moisture conditions, and time for the curing
process to obtain the required strei►gth. If a strength
deficiency, exists as sown by either test record, the
questionable portion 'of the `structu're shall be cored,

shall have the riht to require strengthening or replar.e-
ment, bt the ' tont?actor' s expense, of those portions of
the structure which failed to develop the required strength.
Upon receipt of written request by the Contractor, sub-
standard concrete work may be re-examined in place by
3A-10
non-destructive testing methods or core samples in ac-
cardance with ACI 301 . The Contractor shall retain the
services of an independent testing laboratory approved by
the Engineer and shall bear all expenses without com-
pensation from the Owner. laboratory results shill be
evaluated by the Engineer and the Engineer shall ,make the
final decision on acceptability of the concrete in question.
The Owner may withhold payment for any section of concrete
that does not meet the requirements of these specifications
for placement, lines, finishing, general workmanship or
strength. Withheld payment shall be based on the unit
prices bid for additional concrete and reinforcing steel .
Payment shall be withheld until the unacceptable concrete
has been refinished, removed and replaced or otherwise
brought into conformance with the specifications.
G. MIXING CONDITIONS
1 . General : The concrete shall be mixed in quantities
required for immediate use, and any concrete which is not
in place within the time limits specified in paragraph
0. 4 shall not be used. Retempering ' of concrete will not
be permitted.
20 Gonarete..Temperature: Na concrete shall be place+i when
the temperature of the concrete to be placed is greater
than 40 degrees F. or less than 50 degrees F. The tem-
pereturR of. the concrete to be plated will be taken by
.,; th9 Engineer usfng a thermometer immediately prior to
placement with the point of measurement being in the
chute or bucket
3. Cold Weather No concrete shall be mixed without the
; ., , . apprgval; of the Engineer when the air temperature is at
or below 40 degrees F. (taken in the shade away from
artificial heat) and falling'. If authoriibd by the
Engineer , concrete maybe mixed when the air temperature
is at 35 degrees F. and rising. All cold weather con-
, creting shall be done in accordance with ACI-306,
When permission is given for mixing when the air tempera-
ture is below 40 degrees F. All water used for mixing
shall br: heated to a temperature sufficient to raise the
temperature of concrete to 70 degrees F. , but, the tem-
perature of the a,ixing water shall not exceed 165 degrees
F At ,the ,time of entering the mixer. If heating the
et�xing water only will not raise the placing temperature
of the concrete to 70 degrees F, , then the aggregate must
also be heated, either by steam or dry heat, to a tem-
perature sufficient to raise the plating temperature of
the concrete to the required temperature. In no case
3A-il
Now
shall the aggregate temperature as it enters the mixer
exceed 150 degrees F. The heating apparatus shall be
such as to heat the mass ' of the aggregate uniformly and
preclude the occurrence of hot spots which will burn the
material . Temperatures of transported concrete shall not
be less than 60 degrees F. at the time of placing in the
forms. * Salts, chemicals or other foreign materials
shall not be mixed with the concrete for purpose of
preventing freezing.
*Adequate means shall be provided to maintain the con-
crete and the surrounding air at a minimum temperature of
50 degrees F. for a minimum of 3 days.
4. Hot Weather: Hot weather is defined as any combination
of high air temperature, low relative humidity and wind
velocity that in the judgment of the Engineer would
impair the quality of the concrete. All hot weather
concreting shall be in accordance with ACI-305. Concrete
shall be placed in the forms without the addition of any
m9re water than' required by the design (slump). No
_ . excess water shall be , added on the 'toncrete surface for
finishingi Control of initial 'set of the concrete and
extending the time for finishing operations may be ac-
complished with the use of an approved water-reducing and
: ,set-retarding admixture as ' specified above.
Maximum time intervals between the 'addition of mixing
,water, and/or Cement tol tho , batch 'and the placing of con-
crate in the forms; shall not exceed 'the following:

2.03 MIXING
A. GENERAL MIXING O QUIREMENTS
The mixing shall be done in batch mixer of approved type and
size which will insure the uniform distribution of material
throughout the mass within the specified mixing time and the
discharge of the mixture without segregation. The volume of
the concrete batch shall not exceed the manufacturer' s rated
capacity of the mixer, exclusive of the overload. After all
of the solid ingredients are assembled in the drum, the mixing
shall continue for a minimum time of one and one-half minutes,
providing that all mixing water shall be added before one-
fourth of the mixing time has elapsed. During the mixing

placements or in the case of an emergency, and then only on
the authorization of the Engineer. When hand mixing is per-
mitted, it shall be done on a watertight platform. The fine
aggregate shall be thoroughly saturated with water. Addi-
tional water shall be spread over the fine aggregate and
cement in a uniform layer and the whole mass turned as the
additional water is added. After all ingredients have been
added, the mass shall be turned at least six times , or moe, if
necessary, to make the mixture uniform in color and smooth in
appearance. Hand-mixed batches shall not exceed a two-batch
volume.

embedded items , Lt. , wate�' sto'p3', an, 6r 'bDits , mechani-
3A=16
cal and electrical inferts shall be checked to determine
that they are Yirmly and securely fastened at the loca-
tions shown on the plfAns. They must be free of oil , rust
and anything else that would prevent proper bonding to
the concrete. Voids , when required shall be made by use
of some easily removed material .
2. Aluminum in Contact with or Embedded in Concrete: Where
aluminum anchors , aluminum shapes , or aluminum electrical
conduits are embedded in concrete, all contact surfaces
shall be painted with zinc chromate primer in accordance
with United States Joint Army-N:vy :pecification JAN-P-735.
The paint shall be allowed to thoroughly dry before the
aluminum is placed in cc ' Lact with the concrete.
Aluminum surfaces to be placed in contact with concrete,
wood, or masonry construction, except where the aluminum
is to be embedded in concrete, shall be given a heavy
coat of an alkali-resistant bituminous paint before in-
stallation. The bituminous paint used shall meet the
requirements of United States Military Specification
MIL-P-6983. The paint shall be applied as it is received
from the manufacturer without the addition of any thinner.
All steel or other fgrrous metal tp be mounted on or
placed in contact with dry/cured concrete such as valve
operator floor stands, electrical switchgear, etc. , shall
be painted on the mounting surface in accordance with
PAINTINJ Specification for exterior metal surfaces in
non-critical areas:' '
D. CONSYRJCTION JOINTS
The Joint formed by placing plastic concrete ih 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 structure is specified to be monolithic , the
term monolithic shall be interpreted to mean that the manner
and sequence of ton�rete' Placing Shall be such that construc-
t'io'n' joints 'will not occur. Co'nstructi'dn 'Joints shall be of
the 'type 'ar; spacing shown on the plans. Additional horizontal
end vertical CohstruC,tiomi `jolnts will be considered by the
Engineer upen' requeit ,' but ball not be used without prior
written ap'proVO of the, tn'gineer. The locations and elevations
of ddditional canstru'ction'joints shall 'be subject to the
e prb'val of the Ehg1noor. Con�teu6tion ' oints shall be neatly
thaMffBred three-eighthl Af hn inch (3/g" as directed by the
Engineer.
Unless otherwise provided, lonstruction, joints shall be square
and Hormel to the' formh. ' Bulkheads shall be provided in the
forms fat 'All jbi'rtt e9tept hor'itoht'Li joints.
3A-17.
Horizontal construction joints shall be prepared for receiving
the succeeding lift by cleaning by air-water cutting. The
air-water cutting of a construction joint shall be done at the
Proper time, The surface shall be exposed sound, clean aggre-
gate, The air pressure supply to the jet shall be approximately
onp hundred ( 100) pounds per square inch, and the water pressure
shall be just sufficient to bring the water into effective
influence of the air pressure. After cutting , the surface
shall be washed until there is no trace of cloudiness of the
wash water.
In areas where air-water cutting cannot be satisfactorily
accomplished, or in areas where it is considered undesirable
by the kngirer to disturb the surface of the concrete before
it has 6,,rdened, th; surface shall be prepared for receiving
the next lift by wet sand blasting to remove all laitance and
unsound concrete immediately prior to placing of the next
lift. The surface of the concrete shall be thoroughly washed
after sand blasting to remove all loose material .
Immediately prior to the placing of additional concrete, all
forms ;hall be drawn tight against the concrete in place, and
the surfaces 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 plant , construction joints shall be provided
with concrete keyways, reinforcing steel dowels, ant+ water-
stops. The method of forming keys in keyed joints shall be
such as to permit the easy removal of rorms without chipping,
breaking, or damaging the concrete, in any manner.
3.02 PLACING CONCRETE
A: GENERAL 'RE'qui EM Oi
1 . Preliminary Consideration: The Contractor shall notify
the Engineer upon; completfon of Var##ous portions of the
Work required for, Flacing Concrete io that inspection may
he made as early as .is prhgtic¢¢ie, , Tne Contractor shall
alsok kyob the Cnginger i,nformed .rega�rding his anticipated
concrete lacing ,s4�edule. When All items have been
found to be in order by .the' Engineer including lines and
grades, fo.rms, ;00 nforc,inp, fnserts, piping, electrical ,
p}1�m4 ng and 'th¢¢ Contra4tor's, concreting mo terials and
equipment, the Engineer, tiill then apthorixg the Contractor
to proceed. Unless authorized by the Engipeer, ntj con-
crete shall be p?aced in any unit prior to the completion
of all form-we:rk and the placement of all reinforcement
in that unit;, No concrptb shall oe placed , before the
completipn of all 0djoCent operations which might prove
detrimental to the concrete. Whenever it is necessary to
3A-1B
' I
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 be
completed in the daylight hours. The Engineer reserves
the right to order postponement of the placing operations
when , in his opinion, impending weather conditions may
result in rainfall or low temperatures which will impair
the quality of the finished work. In case rainfall
should occur after placing operations are started, the
Contractor shall provide ample covering to protect the
work.
2. Cleaning Forms: At the time of placing concrete, the
forms shall be clean and entirely free from all chips,
dirt, sawdust, and other extraneous matter. Forms for
slab, beam and girder construction shall not have tie
dire cuttings , nails , matches or any other matter what-
soever, which would mar the appearance of the finished
construction. All forms shall be cleaned to the satis-
faction of the Engineer, and kept free o^ foreign matter
of all kinds during concrete placipb.
3. Embedded Items: Before placing cohcrate, ' care shall be
taken to determine that ell embedded items are firmly and
securely fastened in place. All embedded items shall be
thoroughly clean and free of oil and other foreign material .
Anchor bolts shall be set to Qxact locat16ns by the use
of suitable anchor bolt templates, or as otherwise shown
on tho plans.
B HANDLING ,ANO TRANSPORTING , '
;Chutes , troughs; or pipes +used as aids in placing concrete
shall ,be arranged and used ' so that the ingredients of the
concrete will not be segregated, they shall bk. steel or steel
lined. When steep slopes are necessary, the chutes shall be
equipped with baffles or made in short lengths that reverse ,
the direction of movement. Open troughs and chutes shall ex-
tend, if ,necessary, down insida the forms or through holes
left in the forms# and the'' ends' of such 'chutes shall terminate
in vertical downspouts, M chutes',* trotighs , 'and pipes shall
be kept clean and free from coatings of hardened concrete by a
thorough flushing with water before and after placement.
Mater used for flushing ,shall 'be 'discharged clear of the
concrete in place. Non-agit8ti'hg trucks sha11 ' be used only
when authorized by the Ehginear 'with' due' consideration of the
length of haul , roughness of roads, and' design Of trucks
proposed. Pumping of concrete will be permitted , subject to
approval of the pumping equipment by' the En inebr. The placing
of concrete for floor slabs preferably shall be done by a
3A-19
�fw�w�wm�
i
mixing plant located off the structure. Carting or wheeling
concrete batches on completed concrete floor slab will not be
permitted until the slab has aged at least four curing days.
Unless pneumatic tired carts are used , the carts shall be
wheeled on timber planking so that the loads and impact will
be distriouted over the slab. Curing operations shall not be
interrupted for the purpose of wheeling concrete over finished
slabs.
C. DEPOSITING
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. In thin walls , drop
chutes of rubber or metal shall be used. 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. Each part of the forms shall be filled by depositing
concrete directly as near its final position as possible. The
coarse aggregate shall be worked back from the face and the
concrete forced under and around the reinforcement bars without
displacing them. Depositing large quantities at one point in
the forms and running or working it along the forms will not
be allowed. After the concrete has taken initial set, the
forms shall not be ,barred or any strain placed on projecting reinforcement. LWhere the Contractor' s operations involve the
placing of concrete from above, that is, directly into an
excavated area or thrcugh the completed forms , particularly in
the case of. walls, piers , columns, and similar structures all
concrete. so placed shall be deposited through vertical drop
chutes of rubber or metal of satisfactory site. Drop chutes
shall be made in sections or provided in several lengths so
that the outlet may be adjusted to prepe0 heights dGring
placing operations. Concrete shall not bt- dropped free more
tndn ,five (5) feet. Concrete shall W plectd ' in continuous
horizontal 1 ayers with a depth of from 1 to` 3 feet, depending
upon the wall thickness. , Each layer sha11 be loft when a new
layer is placed upon it; and unless otherwise specified herein
or by the Engineer, not snore ' than one hour shall elapse be-
tweRn the placing of successive layers of concrete in any
portirin of :the structures Included in a eontindous placement.
The Contractor should avoid additional construction joints
other then those shown on plans by placing required sections
Of piers , walls , or, superstructures in one continuous operation.
If; excessive bleeding ,causes water to form on the surface of
the, concrete in tall forms the mix shall be mad., drier to
rduce. the, bleeding. In tall walls the toncreti, shall be
placed to a point about a foot below the top of tho wall , and
at least one ho1ar, or more if specified by the Engineer, shall
be,, Allowed for settling, .. ConcretiAp should then be resumed
and completed before set occurs,
3A•2O
D. CONSOLIDATING
1 . General : Each layer of concrete shall be well compacted
and the mortar flushed to the surface of the forms by
continuous working with mechanical vibrators of an ap-
proved type. Vibrators of the type which operate by
attachment to forms will be permitted only when immersion
type vibrators cannot be used due to inaccessibility.
The vibrators shall be applied to the roncrete immediately
after deposit and shall be moved throughout the layer of
concrete dust placed, and several inches into the plastic
layer below, thoroughly working the concrete around the
reinforcement, embedded fixtures , and into the corners
and angles of the forms until the concrete is thoroughly
compacted. Mechanical vibrators shall not be operated so
that they will penetrate or disturb layers placed pre-
viously which have become partially set or hardened, and
they shall not be used to aid the flow of concrete laterally.
The vibration shall be of sufficient duration to accomplish
thorough compaction and complete embedment of reinforcement
and fixtures + but shall not be done to an extent that
will cause segregation, Vibrators shall be kept constantly
moving in the concrete and shall be applied vertically at
points uniformly spaced, trot farther apart than the
radius over which the vibrator is visibly effective. The
vibrator shall not be held in one location longer than is
required to produce a liquified appearance on the surface,
2. Vibrators: Internal vibrators shall maintain a frequency
when submerged in the concrete of not less than 6,000
impulses per minute for spuds with diameters greater than
5 inches and 10,000 impulses for smaller spuds, The
Intensity (amplitude) of vlbration 'shall be sufficient to
produce satisfactory consolidation. A sufficient number
of vibrators (powered pneuniatidally or electrically)
shall br, used to provide one for each ten cubic yards of
coneret ) per hour being placed. At least une vibrator,
which may be of the gasoline powered type, shall be
immediately available as a standby for each two vibrators
in service. The Engineer may require the Contractor to
use a vibrator of larger siko and power if he feels ,
based on observed performance, that it is necessary to
produce satisfactory consolidation, All vibrators in-
tended for regular service or standby service shall be
checked and approved by the Engineer prior to the be-
ginning of the concreting bporations.
E. PLACING CONCRETE IN COLO WEATHER
No concrete shall be placed when the atmospheric temperature
is at or below ,40 degrees F, (taken in the shade away from
artificial, heat) and falling, unless permission to do so is
3A-21
given in writing by the Engineer. When such permission is
given, or in cases where the temperature drops below 40
degrees F. after the concreting operations have been started,
the Contractor shall furnish sufficient canvas and framework
or other, type of housing to enclose and protect the structure
in such a way that the air around the forms and fresh concrete
can be kept at a temperature not less than 50 degrees F. for a
period of five days after the concrete is placed for normal
concrete, and for three days for high-early-strength concrete.
Sufficient heating apparatus such as stoves , salamanders , or
steam equipment and fuel to furnish all required heat shall be
supplied. It is understood that the Contractor is responsible
for the protection of concrete placed under any and all weather.
F. PLACING CONCRETE IN SLABS
Concrete in columns, walls , and deep beams or girders shall be
allowed to stand for at least one hour, or more if specified
by the Engineer, to permit full settlement due to consolidation
before concrete is placed in the slabs they are to support,
Haunches are considered as part of the slab and shall be
placed integrally with them. When monolithic slabs are placed
In strips , the widths of the strips, unless otherwise specified
or shown, shall be such that thk concrete in any one strip
will not be allowed to lie in place for more than one hour
before the adjacent strips are placed. Immediately before
Placing conerete, . the earth cushion to receive concrete shall
be thoroughly dampened to prevent too rapid absorption of
moisture from the concrete.
3.03 CONCRETE FINISHING
A, FINISHING SLABS
.
1 . General: : Excepties eisewhere permitted in these specifi-
cations or as shown on the drawings ,, all subs, platforms
and steps shall be finished monolithicailw. The following
schedule of finishes shall apply, unless otherwise speci -
fied or shown on the plans:
a. Wood Float Finish: Roofi stabs , manholes , exterior
slabs .except working platforms.
b. Steel Trowel Finish: All interior slabs and steps .
C. Brush Finishm Exterior' steps , walkways , and working
platform.
2. Screeding: As soon as concrete placing operations have
been completed for a slab section of suffitient width to
permit finishing operations`, the concrete sh,ll be approxi-
mately leveled and then struck off, tafnptd, and screeded.
3A-22
The screed shah be of a design adaptable to the use
intended, shall have provision for vertical adjustment ,
and shall be sufficiently rigid to hold true to shape
during use,
The initial strike off shall leave the concrete surface
at an elevation slightly above grade so that , when con-
solidation and finishing operations are completed, the
surface of the slab will be at the grade elevation shown
on the plans. Tamping and screeding operations shall be
continued until the concrete is properly consolidated and
the surface voids are eliminated. The surface shall then
be brought to a smooth true alignment by means of longi-
tudinal screeding, floating , belting, and/or other methods
approved by too Engineer. When templates are used, they
shall be of such design as to permit early removal in
order to permit satisfactory finishing at and adjacent to
the template,
3. Straightness : While the concrete is still plastic , the
surface shall be straightedged by thk use of a standard
ten (10) foot metal straightedge. Each pass of the
straightedge shall lap half of the preceding pass. All
high spots shall be removed and all depressions shall be
filled with fresh concrete and refloated. The checking
with straightedge shell continue during the final finishing
Operation until the surface is true to grade and free of
depressions, high spots , voids, r,r rough spots. The
final surface shall be checked with the straightedge and
• ordinates measured from the face of the straightedge to
the .surface of the slab shall not exceed one-sixteenth
inch per, foot from ,the nearest point of contact and the
, maximum ordI,gaie shall be one-eighth inch per 10 feet.
4. Wood Float Finish: ,. Syrfaces shall be finished using a
wood float to pp true, 'even plane with no coarse aggregate
visible. In the initial floating, while the concrete is
Plastic, sufficiont pressure shall be used on the wood
float to bring' all excess moisture to the surface fo that
it Can be removed. 6 final "light float" finish shall be
given to the surrface, as the concrete hardens. The surface
shall have a , unlform appearance and shall meet the straight-
ness requirements,
S. Steel Trowel Finish: After all surfach moisture has d's-
appeared followinq, the, ,initial wood float finish, surfuces
shall be steel trowelled to a smooth, even, impervious
finish of uniiorm . smoothaess and color, free from biem-
tshra incluping trowel marks.
6, 'Brush Flhish; Following the steel trowel finish , surface
;ot, 'the concrete ,shall be , brushed lightly with a soft-
3A-2i
bristled brush. The brush shall be kept clean and c.hall
be dipped in water frequently so that it will be clean
and wet at all times. Brushing shall be limited to that
necessary to remove the glaze and produce a nonslip sur-
face.
7. Power-Machine Finish (Option): In lieu of hand fin-
ishing, surfaces of slabs requiring wood float finish may
be finished with an approved power finishing machine,
which machine shall be operated in accordance with the
directions of the machine manufacturer. Following machine
finishing, irregularities left by the machine shall be
eliminated by hand trowelling with a steel trowel . Power
machine finishing may also be used as initial step in
finishing surfaces requiring steel trowel finish; how-
ever , for steel trowel finishes the entire surface shall
be given its final finish by hand, using a steel trowel .
Where steel trowel surfaces are to recolve a floor cov-
ering , it is not required that entire surface be hand
