ooted in writing by the Engineer.
Substantial evidence of oollusion for the purpose of
illegally proouring a contraot or perpetrating fraud
on the City in the oonstruotion of the work under
contraot,
When the w rrk is suspended for any rf the causes itemized
above; or for any other cause or causes, the contractor sha 11 dis-
continue the work or such part thereof as the City shall designate,
whereupon the Sureties may, at their option, assume the Contract ow
that portion thereof which the City has ordered the Contractor to
discontinue, and may perform the same, or ma y, with the written
cons ent of the City Council, sublet the work or that portion of
the w ork so taken over, provided, hoeever, that the sureties shall
exercise their option, if at all, within two (2) weeks after the
written :notice to^ discontinue' -the .ork has been served upon the
Contractor and upon the Sureties . -r their authorized agents. The
Sureties in such event shall assume the Coatractor',s place in all
respects and shall be paid by the City for all work performed by
them in accordance with the terms of the contract. All monies re-
ma ining due the Contractor at the time of his default shall there-

Contractor the expense of•aaid cbntract,or labor; ma terials; equip.11
ment and expense incident thereto. The expense so charged shall be
deducted by the City out of such monies as ma y be due or may at any
time thereafter become due the Contractor under and by virtue of the
contract or any pa rt thereof. The City shall not be required to
obtain the lowest bid for the work of completing the contract, but
the expense to be deducted sha 11 be the actual cost of such work.
In case such expense is less than the sum which would have been pay-
able under the contract if the same had been completed by the Con-
tractor, then in.-such oase the City may pay to the Contractor the
difference in the cost provided that the Contractor shall not be en-
titled to any claim for damaged or for loss of anticipated profits.
In case such expense shall exceed the amount which would have
been payable under the contract, if the same had been completed by
the Contractor, thenthe•Centrsctor and his Sureties shall pay the
amount of such excess to the City on notice from the City Council
of the exooss due. :Then any particular part of the work is being
carried on by the City by contract or otherwise, under the provisions

Engireer will make an approximate estimate of the value of the work
dine during the month under the speoifioations. On partial estimates
eighty --rive 185.0 per oent of suoh estimated stmt will be paid the
Contraotor on cr before the fifteenth=—._ day of the month next follow-
ing, The partial estimate made will inolude aooeptable non- .perish-
able materials delivered to the work. such payment will be allowed
on the basis of eigh -five per oent of net invoioe value. The Con-
tractor shall furnish to the Engineer snot: detailed information as
he may request, to aid him as a guide in the preparation of partial,
e.atimstes.
It is understood that the partial estimates from month to
month will be approximate only and all partial monthly estimates
and payments will be subject to correction in the estimate rendered
allowing for the disoovery of an error in any previous estimate,
and such estimate shall not. in any respect, be taken as an ad-
mission of the City of the amount of work done or of its quality or
suffioieroy nor as an acceptance of the work or the release of the

Engineer may result in conditions that will adversely affect
the quality of the concrete to be placed, the Engineer may .
order postponement of the work. Where work has been started
and changes in weather conditions require protective
measures to be used, the Contractor shall provide adequate
shelter to protect the concrete from damage from rainfall
or damage due to freezing temperatures. In case it is
necessary to continue mixing operation during rainfall, the
Contractor shall provide protective coverings for the
material stock piles as well as for the concrete being
placed. The covering for aggregate stock piles will be
required only to the extent as may be necessary to control
the moisture conditions in the aggregates so that adequate
control of the consistency of the concrete mix may be main-
tained.
No concrete shall be mixed without the approval of
the Engineer when the air temperature is at or below 40
degrees F. and falling, and then, only under conditions
approved by the Engineer.
Mixing and Mixing Equipment:
The mixing shall be done in a batch mixer of approved
type and size which will insure the uniform distribution
of the material throughout the mass so that the mixture will
be uniform in color and smooth in appearance.
After all the ingredients are assembled in the drum,
the mixing for other than pipe shall continue for a minimum
time of one and one -half (1 -1/2) minutes. During the mixing
time, the drum shall revolve at a speed of fourteen (.4) to
twenty (20) revolutions per minute. The mixer shall be
equipped with a speed regulator to hold the mixer to its
normal speed of revolution.
The entire contents of the drum shall be discharged
before any materials are placed therein for the succeeding
batch.
The concrete mixer shall be equipped with an automatic
timing device so constructed that it is put into operation
when the skip is raised to its full height and dumping.
This device sriall satisfactorily lock the discharging mechanism
to prevent emptying of the mixer until all the materials
have been mixed together for the minimum time required.
Whenever a concrete mixer is not adequate or suitable
for the work, it shall be removed from the site upon a
written order from the Engineer and a suitable mixer provided
by the Contractor. Pick -up and throw -over blades in the
drum of the mixer which are worn down more than twenty -five
(25) per cent in depth shall be repaired or replaced by new
blades.
Concrete improperly mixed shall not be placed in the
structure.
Hand mixing of concrete will be permitted only for
small placements or in the case of an emergency and then
only on the authorization of the Engineer. When hand mixing
is permitted, it shall be done on a water -tight platform.
The fine aggregate and cement shall first be mixed until a
uniform color is attained and then spread over the mixing
board in a thin layer. The coarse aggregate shall then be
spread over the fine aggregate and cement in a uniform layer
and the whole mass turned as water is added. After all
ingredients have been added, the mass shall be turned at
least six times, or more if necessary, to make the mixture
uniform in color and smooth in appearance. Hand mixed
batches shall not exceed a two (2) bag batch in volume.
Placing, Curing and Finishing;
The work of placing, curing, and finishing shall follow
specifications set out elsewhere herein.
Measurement:
This item shall follow specifications set out elsewhere
herein.
Payment:
Payment will be made in accordance with the provisi)n
for payment set-out elsewhere in the specifications.
Ready Mixed Concrete:
Ready mixed concrete complying with the specifications
far Classes "A ", "B ", "C ", and "AA ", concrete and equipment
herein will be approved when prepared under A.S.T.M.
"Standard Specifications for Ready Mixed Concrete ", Serial
Designation C -94, with the exception as follows:
Paragraph 22: "Time of Hauling" now reads: "Discharge
-from the hauling container shall be completed within a
period of 1 -1/2 hours ".
This shall be changed to read: "Discharge from the
hauling container shall be completed within a period of
30 minutes after water has been added to the batch ".
Hatching Plants or Central Mixing Plants:
Batching plants or central mixing plants shall be of
sufficient capacity to keep the work progressing satisfac-
torily. Machinery shall be in good condition and well
maintained, and shall meet the approval of the Engineer
as to adequacy, condition and operation.
In case concrete is obtained from a commercial batching
plant, such a plant shall be equipped with duplicate units,
so that in case of a breakdown at least one unit will always
be available for this project.
Concrete Tests:
During progress of the work and for each different mix
of concrete, a set of three (3) standard six (6) inch
concrete cylinders shall be made and tested where from
25 to 100 cubic yards of concrete are placed during any
day's operation; also an additional set of tests shall be
made for each 100 cubic yards or major fraction thereof
over and above the first 100 cubic yards.
Cylinders of each set shall be molded from the samples
of concrete, one to be tested at seven (7) days and two
to be tested at twenty -eight (28) days. Tests shall be
in accordance with A.S.T.M. Serial Designation C -31,
with curing according to Paragraph 7 -A..
(a) Slump Test: A slump test shall be made
for each fifty (50) or less cubic yards of concrete placed
in one operation. This test shall be made in accordance
with A.S.T.M., Serial Designation D -132.
DEPOSITING OF CONCRETE
Preparatory Work:
Before depositing concrete, debris shall be removed from
the space to be occupied by the concrete and forms shall
be thoroughly wetted. Reinforcement shall be thoroughly
secured and approved by the Engineer.
Handling and Gunveying:
Concrete shall be handled from the mixers to the place
of deposit as rapidly as practicable by methods which shall
prevent the separation of or loss of the ingredients. It
shall be deposited as nearly as practicable in its final
position in the forms. It shall not be run along non raked
along the forms, but it shall be deposited so as to maintain,
until the completion of the unit, a plastic surface approxi-
mately horizontal. Forms for walls, or other thin sections
of considerable height, shall be provided with openings
or other devices that will permit the concrete to be placed
in a manner that will avoid accumulation of hardened concrete
on the forms or metal reinforcement.
Chutes:
When concrete 13 conveyed by chuting, the plant shall
be of such size as to insure a practically continuous
sliding in the chute, and of such design as will permit a
free and ready movement of the discharge end of the chute
along the forms, permitting the deposit of the concrete in
place without raking of same. The angle of the chute
with the horizontal shall be such as to allow the concrete
to flow without separation of the ingredients, and the
delivery end of the chute shall be as close as is possible
to the point of deposit. The chute shall be thoroughly
flushed with water before and after each run, or thoroughly
cleaned by other means after each run, and water used for this
purpose shall be discharged clear of the work.
Concrete chutes shall be covered where necessary to
prevent loss of material, and shall be of metal or fully
metal lined.
Vibrating Concrete:
Concrete, during and immediately after depositing, shall
be thoroughly compacted by means of internal vibrators of
an approved type and size. The concrete shall thoroughly
worked around the reinforcement and among the embedded
fixtures and into the corners of the forms.
The following paragraph shall apply to thin slabs
and walls at points where thin slabs are deposited without
requiring forms on both faces:
Concrete shall be thoroughly tamped and puddled around
the reinforcing and into position.
Depositing Concrete Slabs:
On the bottom and sloping slabs of structures, before
depositing concrete, the earth shall be hand dressed to a
firm bearing. If excavation is carried below grade, it
shall be backfilled with concrete.
Before depositing such slabs where shown on the plans,
the earth surface on which the concrete is to be laid shall
be covered with a layer of sisal kraft paper, or an
approved equal, well lapped and fastened firmly in position.
The concrete shall be deposited on top of this waterproof
paper. This waterproof paper shall conform with General
Requirements, Paragraph 2, A.S.T.M. Designation C171 -42T.
Joining New Concrete to Old:
Before depositing concrete against that which has set,
the forms shall be retightened.. Smooth surfaces of the
set concrete shall be roughened to a depth of one -half (1/2)
inch, thoroughly cleaned of foreign matter and laitance
and saturated with water. To insure bond, the new concrete
placed in contact with hardened or partially hardened
concrete shall contain an excess of mortar. If required,
the cleaned and saturated surfaces of the hardened concrete,
including vertical and inclined surfaces, shall first be
covered with a sprinkling of neat cement, against which the
new concrete shall be placed.
Construction joints shall be located as approved by
the Engineer, and formed so as to least impair the appearance
and strength of the structures.
Unless specified otherwise in writing by the Engineer,
no concrete shall be deposited against earth side walls.
Where it is desired to cast concrete against forms
which are to be left in place, such process shall be subject
to the approval of the Engineer.
Removal of.Water:
Water shall be removed from the excavation before the
concrete is deposited. Any flow of water into the excavation
shall be directed through proper side drains to a sump,
or removed by other approved methods which avoid washing
the freshly deposited concrete. After the concrete has
thoroughly hardened, water vent pipes shall be filled by
grouting.
Curing Concrete:
Curing the concrete on this project is considered to
be of major importance.
Exposed surfaces of the concrete shall be kept wet
continuously for a period of not less than seven (7) days
after the time of depositing concrete. Concrete shall be
cured with wet mats, or an equally efficient method
approved by the Engineer .
During the specified finishing operations, such
covering, when required, shall be removed only for a
minimum period of time and over a minimum area necessary.
Mats used in curing shall be firmly anchored in place
at all times. Concreting shall not be commenced until
approved means for curing have been fully provided.
Working on Concrete:
No materials or equipment shall be stored on the walls
or floor of structural members at any time, and forms or
workmen shall not be allowed thereon while curing except
for finishing and curing operations. When it becomes
necessary, in the opinion of the Engineer, for loads to be
aupported on such members, or for workmen to operate there -
from, such protection of surfaces and bracing under slabs
and beams shall be installed as the Engineer may direct.
Finishing:
Each and every part of the concrete work shall be
carefully and neatly finished. Immediately after the
removal of forms, all surfaces, whether to be exposed or not,
shall have all honeycombed areas cut out and replaced or
pointed up as required by the Engineer, using cement mortar
of the same mixture as that used in the concrete.
Surface finishing shall be as follows:
Exterior surfaces shall be finished to 12" below
surrounding grade.
Exterior walls - rubbed.
Interior of reservoirs - form finish, rough ridges
removed.
Floor of reservoirs - float finish.
Unexposed columns - form finish, rough edges
removed.
Rocf and interior - same as unexposed columns.
Exposed intake - float finish, on exposed surfaces
and floor. .
Inner surfaces of concrete pipe or conduits -
smooth or rubbed finish on sides and top. Bottom
troweled finish.
Valve boxes - exterior, rubbed finish; interior,
form finish.
Structural exposed surfaces, rubbed.
Walks, curb and gutter - float finish.
As soon as forms are removed, all necessary
pointing up shall be done. When the pointing has set
sufficiently to permit, all surfaces requiring a carborundum
finish shall be wet with a brush and given a thorough
rubbing with a Number 16 or finer carborundum stone or an
abrasive of an equal quality. The rubbing shall be continued
sufficiently to bring the surface to a paste, to remove all
form marks or other projections, and to produce a smooth,
dense surface without pits or irregularities. The use of
cement to form a surface paste will not be permitted. The
material which has been ground to a paste in this process
shall be carefully spread and brushed uniformly over the
surface and allowed to take a reset, the brushing to be in
uniform striping.
Areas to be float finished shall have the top surface
floated with a wooden float until a slight excess of sand
appears. Outer edges and joints shall be rounded with
approved tools suitable to the radii.
During the process of conditioning a completed structure
for final acceptance, the surface above 1 foot below grade
shall be cleaned from drip marks and discolorations, washed
down and broomed so that the entire structure is left a
neat, clean and uniform appearing finish and color.
The interior surfaces of all structures, pipe, manholes,
and storm sewers, shall be smooth. Form marks and rough
spots shall be rubbed down with a carborundum stone.
CONCRETE SURFACES SHALL NOT BE PAINTED WITH A CEMENT
GROUT.
Marking Concrete Construction:

and width.
Exposed edges of steps, surface -beams and other surfaces
shall be rounded with a steel tool, true to line and depth
of radius and shall be given the specified finish.
Expansion Joints:
Expansion joints shall be constructed in accordance
with the plans.
Expansion joint material, "Elastite ", "Hornex ", as
manufactured by the A. C. Horm Company, or equal material,
shall be used where shown on the plans. Material of "Elastite"
type shall be cast into the first pouring of the concrete in
such a manner as to hold the joint material firmly in position
and true to line when forms are removed and during the
pouring of the adjoining concrete. Other types of material
shall be placed in accordance with the directions of the
manufacturer, but in a manner to secure a neat finish.
Expansion joints on reservoirs or surge tanks or
structures subject to hydrostatic pressure work shall be
treated as follows:
After the concrete has set the expansion joint
material, which has already been cast in place, shall be
caulked in the joint by means of an air hammer equipped with
a steel caulking iron about six (6) inches in length and the
width of the expansion joint. After thoroughly caulking
the cast in place joint shall be filled slightly above the
concrete surface with an asphalt compound, poured on an
approved primer paint coat.
Where expansion joints are exposed and are not part of
a structure under hydrostatic pressure, the expansion joint
shall be neatly trimmed, flush with the surface of the
concrete, upon completion of finishing.
Construction Joints:
Construction joints on reservoirs or other structures
subject to hydrostatic pressure will not be permitted in
the work except where shown on the plans. If for any
reason a section of wall extending between expansion joints
cannot be completed in a continuous operation with a plastic
face of concrete at all times not in excess of thirty (30)
minutes old, concrete in such section shall be removed and
the section repoured in its entirety.
Where construction joints are permitted, in structures
designed for hydrostatic pressure, there shall be installed
a continuous water -stop in the joint. This water -stop may
be of copper if available, 16 gauge. If copper is not
available, 16 gauge galvanized iron or other available
material approved by the Engineer shall be used.
Initial Set of Concrete:
Where, in these specifications, a time limit of thirty
(30) minutes has been set before which concrete shall be
deposited in place after leaving the mixer, such time limit
shall govern unless tests from time to time show, in the
opinion of the Engineer, that such time limit should be
shortened or that such time limit may be lengthened without
affecting the characteristics of the concrete. No change
in such time limit shall be made without the written
approval of the Engineer.
CONCRETE CRADLE
Concrete cushion, cradle, or protection, where
required, shall be constructed as shown on the plans,
or where not shown on the plans, as directed by the

tion of pipe sewer according to the plans, except where tunnel-
ing is oonsidered necessary or proper by the Engineer.
The excavation of the trench shell not advanoe more than
three hundred (300) feet ahead of the completed pipe work, ex-
oept where, in the opinion of the Engineer, it is neoessary
because of wet ground. The bottom of the trench shall be shaped
so as to oonform as neaprly as possible to the outside of the
pipe. parbioular Dare being taken to recess the bottom of the
trenoh in duoh a manner as to relieve the bell of the pipe of
all load. Under the barrel of the pipe the ditoh shall bo so
trimmed to grade that the barrel of the pipe will have full .
bearing throughout its length.
Pipe sewers shall be built in a trench, the width of whioh,
at the top of the pipe, shall not exceed the external diameter
of the pipe plus eight (8) inches. A greater width may be per.
mitted by the Engineer to sheet the trench. The sides of the
trenoh shall at all times be maintained vertioel. end if ne-
oeesary, by sheeting and braoing.
The Contraotor shall do no tunneling, except upon written
permission from the Engineer. If permitted, the tunnel shall be

property. When, in the opinion of the Engineer, aho.ting or
shoring oannot be safely removed, it shall be left in place,
The Contraotor shall be paid for the lumber so left in plaoe
at the prioes bid. Timber left in plane shall be out off at
least two (2) feet below the surface. In case the timber,ia
left in plane. no thickness of sheeting over two (2) inches, and

shaped to give a full support to the lowrrri third the a h pipes
and, if necessary to seoure a proper 6
layer of fine gravel or other suitable material shall be plowed.
The same means o£ securing a firm foundation shall be adopted
in case the excavation has been made deeper than necessary.
If there is not a good natural foundation, the pipes shall
be laid in a masonry oradie supported on a foundation carried
to a soil of satiefactory bearing power, er supported on a
structure designed to parry the w►ight of a pipe and its load
to a firm bearing.

Pipe shall be laid in a000rdanoe with the beat praotioe in
the oonetruotion of storm sewer pipe lines. Excavation for
pipe shall be made true to line and grade, and the pipe shall
be thoroughly bedded throughout. The open end of the pipe
aha11 be securely closed at the end of eaoh dayle work. When
the diameter of the pipe permits, the joints shall be finished
inside by men working inside the pipe. When completed the
inside of the pipe line throughout shall be oleaned and free
from any obatruotions.
Trenohea shall be kept free from water until the material
in the joints has auffiooiently hardened.
Where tongue and groove pipe is used the annular spade be.
tween the tongue and groove shall be filled with mortar, and
there shall be a band of mortar not less than one -half (1/2)
inch in thiokness wiped around eaoh joint of the pipe line.
Where possible, the joints shall be wiped inside with a wet
brush. After the pipe joint is oompleted the entire body of
the pipe, inoluding the joint, shall be protected from the sun
by wet burlap. This burlap shall be kept wet by eprinkling
for a period of twenty-fcur (24) hours, after Mich time the
burlap shall be removed and the pipe joints inepeoted and if
found satisfactory the pipe shall be protected with a light
covering of earth. As soon as the joints have sufficiently set
the baokfilling shall be completed. If butt joints and coilsss
are used on the pipe, the joints shall be thoroughly oaulkod
with dement mortar and finished smooth,
The Contractor shall oonetruot all storm trenoh pips line
structures, and special inlets, outlets, eto., as shown on
the plans or as ordered by the Engineer. None but pipe lavers
