The Authority shall not be liable for any damage incurred by the Contractor
due to any delays in construction or installation due to causes of "Force
Majeure".

(3) The Contractor shall have no liability whatsoever for destruction

Contractor shall be as fully responsible to the Authority for acts and omis-
sions of the sub-contractor and of the persons either directly or indirectly
employed by his sub-contractor as he is for the acts and omissions of persons
directly employed by him. If any such sub-contractor fails to perform the
work undertaken by him in a manner satisfactory to the Engineer, his sub-
contract shall be immediately terminated by the Contractor upon written
notice from the Engineer. Nothing contained in any sub-contract shall create

(1) In the event of any question or dispute arising under or in con-
nection with the Contract, the same shall be referred to the award of a sole
arbitrator agreed to by both the parties or, failing such agreement, to the

DESCRIPTION OF PROJECT AND WORK

3. 1 Location of Project.

(1) The Mangtanwala Unit of Salinity Control and Reclamation Project No. 4
(Upper Rechna Doab) is situated in the former Punjab area of West Pakistan in the northern
half of the Indus Valley. The Indus Valley is a vast alluvial plain, varying in width from
100 to 300 miles and extending some 800 miles from the foothills of the Himalaya Moun-
tains to the Arabian Sea. Topographically the valley is virtually flat, having a gentle
slop of about one foot per mile in the direction of the flow of the rivers toward the sea.
The Indus River flows near the westerly limits of the valley and within the region flow
four of the major tributaries of the Indus: the Jhelum, Chenab, Ravi and Sutlej Rivers.
The soils are fertile and much of the land of the Indus Valley, including areas in which
tubewells are to be construction, is irrigated by some of the largest irrigation systems in
the world.

(2) Karachi is the largest city, with a population of about two million, and
the only seaport of West Pakistan. Lahore, the headquarters of the Authority and a city
of about one and one-half million inhabitants, is situated about 750 air miles northeast of
Karachi at an elevation of aBout 650 feet above sea level. The present seat of the Central
Government of Pakistan is at Rawalpindi, about 150 miles north of Lahore. The general
area of the Project is served by both roads and railways from Karachi, Lahore, and other .
centers.


3.2 Description of Area.

(1) The northern third of Rechna Doab, which is embodied in Salinity Control
and Reclamation Project No. 4, has for planning and construction purposes, been sub-
divided into a number of individual project areas. The Mangtanwala Unit extends over
an area of about 250,000 acres in Upper Rechna Doab between the Southern Boundary of
Salinity Control and Reclamation Project No. 1, right bank of Ravi River and the Lahore-
Sheikhupura rood. The general location of the area is shown on the Drawings included
in the Contract Documents. Most of the lands embodied in the Unit area are now irrigated
with canal water supplied by the canal system off-taking from the Upper Chenab Canal as
shown on the Drawings. In general, the tubewells will be located alongside, or in the
vicinity of distributaries, branches, minors, and lesser canals of the irrigation system, and
spaced at intervals varying from approximately one-quarter to two miles apart.


3.3 Climatological Data.

(1) The Mangtanwala Unit area is situated at elevations varying from approxi-
mately 600 to 650 feet above sea level. The climate is hot, except during the winter
months of November to February. Annual precipitation varies from an average of approxi-
mately 18 inches in the vicinity of Shahdara to 12 inches at the southern tip of the unit
area. However, the amount of rain occurring in individual years may vary between wide
limits. Most of this precipitation generally occurs during the monsoon rains of July and
August.

DESCRIPTION OF PROJECT AND WORK

3. 1 Location of Project.

(1) The Mangtanwala Unit of Salinity Control and Reclamation Project No. 4
(Upper Rechna Doab) is situated in the former Punjab area of West Pakistan in the northern
half of the Indus Valley. The Indus Valley is a vast alluvial plain, varying in width from
100 to 300 miles and extending some 800 miles from the foothills of the Himalaya Moun-
tains to the Arabian Sea. Topographically the valley is virtually flat, having a gentle
slop of about one foot per mile in the direction of the flow of the rivers toward the sea.
The Indus River flows near the westerly limits of the valley and within the region flow
four of the major tributaries of the Indus: the Jhelum, Chenab, Ravi and Sutlej Rivers.
The soils are fertile and much of the land of the Indus Valley, including areas in which
tubewells are to be construction, is irrigated by some of the largest irrigation systems in
the world.

(2) Karachi is the largest city, with a population of about two million, and
the only seaport of West Pakistan. Lahore, the headquarters of the Authority and a city
of about one and one-half million inhabitants, is situated about 750 air miles northeast of
Karachi at an elevation of aBout 650 feet above sea level. The present seat of the Central
Government of Pakistan is at Rawalpindi, about 150 miles north of Lahore. The general
area of the Project is served by both roads and railways from Karachi, Lahore, and other .
centers.


3.2 Description of Area.

(1) The northern third of Rechna Doab, which is embodied in Salinity Control
and Reclamation Project No. 4, has for planning and construction purposes, been sub-
divided into a number of individual project areas. The Mangtanwala Unit extends over
an area of about 250,000 acres in Upper Rechna Doab between the Southern Boundary of
Salinity Control and Reclamation Project No. 1, right bank of Ravi River and the Lahore-
Sheikhupura rood. The general location of the area is shown on the Drawings included
in the Contract Documents. Most of the lands embodied in the Unit area are now irrigated
with canal water supplied by the canal system off-taking from the Upper Chenab Canal as
shown on the Drawings. In general, the tubewells will be located alongside, or in the
vicinity of distributaries, branches, minors, and lesser canals of the irrigation system, and
spaced at intervals varying from approximately one-quarter to two miles apart.


3.3 Climatological Data.

(1) The Mangtanwala Unit area is situated at elevations varying from approxi-
mately 600 to 650 feet above sea level. The climate is hot, except during the winter
months of November to February. Annual precipitation varies from an average of approxi-
mately 18 inches in the vicinity of Shahdara to 12 inches at the southern tip of the unit
area. However, the amount of rain occurring in individual years may vary between wide
limits. Most of this precipitation generally occurs during the monsoon rains of July and

3.4 Geology.

(1) All of the tubewells will be situated in the Indus Valley Alluvium
which consists, in general, of fine-to-medium-grained sand of much greater
depth than the depth of penetration of the tubewells. In general, the upper-
most part of the formation is composed of fine sand, silt, and clay with coarse
sand being more commonly found at increasing depth. The entire formation
is.interspersed with occasional beds or lenses of silt and clay. Within the
areas where the tubewells are to be constructed, the present ground water
surface lies at depths varying from a few feet up to 20 feet below the ground
surface.




3.5 Description of Tubewells.

(1) The tubewells are to be constructed as a means of lowering the level of
the ground water within the area, as well as supplying supplemental water for irrigation
of lands which are now served with canal water supplies. Each tubewell will have a
minimum design discharge capacity determined on the basis of the culturable area under
its command and the canal supplies available to the area.

GENERAL
CONDITIONS

(2) All tubewells are to be drilled with reverse circulation rotary drill rigs.
The diameter of the drill bit and the total depth of the tubewells will vary depending
upon the capacity of the tubewell and the materials encountered. An accurate drilling
log of each tubewell is to be made, and samples taken of the materials through which the
tubewell is drilled.

(3) Upon the completion of drilling, blank and slotted fiberglass tubewell
casing sections, either 8 or 10 inches in diameter, are to be place in the tubewell for the
specified lengths. Steel pump housing casing is then to be connected to the tubewell
casing by means of a concentric tapered reducer and installed in the tubewell. The pump
housing casing is to be 14 or 16 inches in diameter, depending on the size of the pump
to be installed.

(4) After installation of the pump housing and tubewell casing, the tubewell
is to be shrouded (packed) with selected gravel, varying in size from No. 16 to 3/8-inch.
The tubewell is then to be developed and tested until it will efficiently produce clear
water at a pumping rate of 150 percent of the design capacity. When the tubewell has
been satisfactorily developed and tested, a concrete pump pedestal and floor slab are to
be constructed. Each tubewell is to be equipped with a deep-well, vertical turbine pump,
direct-connected to a vertical, hollow-shaft motor. All motor controls and accessory
electrical equipment are to be installed and connected and the equipment placed in
operating condition and tested to demonstrate that the entire installation meets the
requirements of the Contract Documents.

(5) A brick masonry pump house with removable roof is to be constructed to
house the pump, motor, motor controls and accessory electrical equipment and a brick
masonry discharge box is to be constructed at the outlet of the pump discharge pipe.

(6) The connection of the electric equipment to the power source is not the
responsibility of the Tubewell Contractor. The construction of facilities to convey water
from the outlet of the discharge box to its point of use is not a part of this Contract.


3.6 Number and Sizes of Tubewells.

(1) The capacities of individual tubewells will vary from two to five cusecs
each in one-cusec increments. It is anticipated that the total depths of the tubewells
will vary from 180 feet to 400 feet with an average estimated at between 250 feet and 300
feet. The pump housing casing will extend approximately 50 to 60 feet below ground
surface. Pump Total Head will vary from approximately 40 to 50 feet, and the horsepower
rating of the pump motor and the motor control will vary with the capacity and pump head
established for each tubewell. The approximate number of tubewells to be constructed for
the various capacities and pump heads are as follows:

stabilizing the bore hole when such use is specifically approved by the Engineer.
If necessary, temporary casing shall be furnished and installed by the Con-
tractor to hold the walls of the hole during drilling operations and until the
gravel shrouding has been placed. All temporary casing shall be removed by
the Contractor in 5- to 10-foot stages as the gravel shrouding is placed. The
temporary casing may be new or used and shall remain the property of the
Contractor.

(6) If, in the opinion of the Engineer, it is necessary to discontinue
work on any bore hole because it is out of line more than the amount specified
or on account of jammed tools, caving ground, or because of negligence on
the part of the Contractor, the Contractor shall drill another bore hole at
an alternative location designated by the Engineer. The Contractor will not
be entitled to payment for any work done or materials furnished for bore
holes abandoned as a result of his operations or negligence.


4. 3 Data and Records.

(1) The Contractor shall keep an accurate drilling log of each bore
hole, including a description of all materials encountered and their location
in the bore hole. The fact that the Engineer or his representative may be
present and keeping a separate record shall not release the Contractor from
this responsibility. In the case of defective or incomplete records, the Con-
tractor shall complete the records at his own expense. All records and data
shall be kept by the Contractor on forms approved by the Engineer. The
Contractor shall deliver to the Engineer the original of all records, and all
such records shall become the property of the Authority.

casing assembly straight, plumb, and concentric in the drilled hole to permit
the installation of the pump in such a manner that it will operate satisfactorily
and without damage. The methods employed by the Contractor in the installa-
tion of the casing and in obtaining or correcting the verticality and straight-
ness of the pump housing casing shall be subject to the approval of the
Engineer.

(2) Centralizers, spacers or other suitable devices shall be attached to the
tubewell casing so that it will be centered in the drill hole throughout its entire length
and held in such position while gravel shrouding is being placed. Centralizers may con-
sist of metal brackets, fiberglass lugs on the fiberglass couplings, wooden blocks cemented
or otherwise attached to the pipe or couplings, or other suitable devices or materials that
will ensure that the casing pipe is accurately centered in the drill hole. The material and
design of the centralizers and method of their attachment to the pipe or couplings shall be
subject to the approval of the Engineer.

(3) The Contractor shall install the pump housing casing so that the
deviation of its axis from the vertical shall not exceed 1-1/2 inches at the
bottom of the pump housing casing. Measurements for determination of
verticality and straightness of the pump housing casing shall be made by the
Contractor in the presence of the Engineer upon completion of the gravel
shrouding.

(4) Measurements for determining the deviation of the pump housing
casing from the vertical shall be made by the use of a circular plumb having
a minimum outside diameter of 1/2-inch less than the inside diameter of

from the center of the pump housing casing at the top by.ro're than that
.corresponding to a,deviation of the plumb of 1-I/2 inches at the bottom of
the pump housing casing. All deviations shall refer to a vertical line pasting
through the center of the pump housing casing at the top of the pump housing
casing.

(5) Straightness shall be determined by lowering a section of pipe
40 feet long or a dummy of the same length to the bottom of the pump housing
casing. The minimum outside diameter of the pipe or dummy shall be
1/2-inch less than the inside diameter of the pump housing casing. If a dummy
is used, it shall consist of a rigid spindle with three cylindrical rings, each
ring having a height of at least 12 inches. The rings shall be true cylinders
and shall be located at each end and in the center of the dummy. The central
shaft of the dummy shall be rigid so that it will maintain the alignment of the
axis of the cylindrical rings. The pump housing casing shall be sufficiently
straight so the pipe or dummy can be passed freely throughout the entire
length of the pump housing casing. Plumbs, pipes and dummies used in these
tests shall be approved by the Engineer.

(6) Any tubewell failing to meet the specified requirements for ,
straightness, verticality and concentricity shall be abandoned, and the Con-
tractor shall construct a new well at his own expense at an alternative site
designated by the Engineer.

(7) After completion of installation of the pump housing casing and
approval of the installation by the Engineer, the Contractor shall paint the

for gravel shrouding for the uncased length of the bore hole which is backfilled
with gravel shrouding material.


4. 10 Gravel Source.

(1) There is no known source of gravel suitable for tubewell shroud-
ing within the Project. Investigations which have been made to date indicate
that deposits of usable gravel are located some 200 miles northwest.of Lahore.
Accessible sources of gravel for shrouding are located on the Campbellpur-
Pindi-Ghaib metalled road, some 3 to 5 miles from the Campbellpur rai' ead.

(2) The site is geneiallv suitable for the installation of a screening
plant, although the deposit area may be expected to be inundated during flood
periods and it may be necessary to stockpile gravel in order to operate the
screening plant continuously during such periods.

(3) The gravel source and plant site will be made available free of
charge to the Contractor for the production of gravel for shrouding, aggregate
for concrete, and other uses as required by the Contract Documents and as
directed by the Engineer. All gravel processed from sources made available
free of charge to the Contractor and not used for the performance of the work
specified herein shall revert to and become the property of the Authority.

of work involved nor the amount of materials it will be necessary to waste
in order to obtain the required amount of suitable gravel. Upon withdrawal
from the site, the Contractor shall remove all structures and equipment and
shall grade and clean up the site as directed by the Engineer.

(5) The Contractor may obtain gravel from alternative locations,
subject to the approval of the Engineer, provided that the gravel meets the
requirements of the Specifications, and that there is no additional cost to the
Authority.


4. 11 Installation.

(1) The annular space between the outside of the casing assembly and
the wall of the drilled hole shall be gravel shrouded by the Contractor from
the bottom to the top of the tubewell in such a manner that there will be no
voids other than the intergranular space between the gravel particles. If,
at the Engineer's direction, the bore hole is not cased the full depth designated
to be drilled, the uncased length of the bore hole shall be filled with gravel
shrouding.

(2) The Contractor shall furnish all gravel used for shrouding vhich
shall be clean, hard, well-rounded, washed, carbonate free, and water worn,
without thin, flat particles and with the following gradations:

DEVELOPMENT
AND TESTING


DEVELOPMENT AND TESTING


4. 12 General.

(1) Development and testing shall consist of all work required in
connection with the development of each tubewell to produce the design capacity
of relatively sand free water with a minimum drawdown, and the testing of each
tubewell to determine the effectiveness of the development operations as speci-
fied herein or as directed by the Engineer. Development and testing shall
include, but not be limited to, surging, backwashing, and pumping the tubewell
at higher than rated capacity; testing the tubewell for specific capacity, sand
content and degree of development; and sterilizing and sealing each tubewell.

(2) Measurement for development and testing of tubewells will be
made of the number of tubewells developed, tested, and accepted by the
Engineer.


4. 13 Development.

(1) The development procedures and methods used for development
of the tubewells shall be established by the Contractor subject to approval
by the Engineer, and the development operations shall be witnessed by
the Engineer from their initiation to their completion. The Contractor
shall maintain a complete record of the development operation and shall
make regular periodic measurements of discharge rates, sand content
and water level measurements. The procedures used shall include back-
washing and pumping at higher than rated capacity and may include surging
or similar procedures determined by the Contractor.

(2) The development of the tubewell shall be performed for a minimum
of six hours by step pumping, backwashing, and surging the tubewell with a
vertical turbine pump. The Contractor may notify the Engineer at any time
following the completion of the six-hour pumping period that the tubewell is
ready for testing.


4. 14 Testing.

(1) The Contractor shall test each tubewell under the Engineer's
direction as described herein. Upon completion of the development oper-
ations the tubewell shall be permitted to recover for a minimum period of
one hour. During this recovery period, the tubewell shall be sounded.
If the comparison of the depth by sounding and the length of the casing, string
indicates there is more than six feet of material in the tubewell, it shall be
cleaned to within two feet of the bottom of the casing.

3-31-65 STD
E-10





DEVELOPMENT
AND TESTING


(2) Following the recovery period, the tubewell shall be pumped
at 150 percent of rated capacity for a period of one hour. The water pumped
shall at all times be clear and free from turbidity. At the end of the first
five minutes of pumping, the sand content of the water shall be determined
by using a 1000-milliliter Imhoff cone or other device approved'by the
Engineer. The sand content of the water at this time shall be less than
100 ppm. A second sand content determination shall be made 10-minutes
after the start of pumping. The sand content at this time shall be less than
30 ppm. If the sand content tolerances are exceeded at this time, or at
any subsequent time up to the time of final acceptance of the installation,
while pumping at the rate of 150 percent of design capacity or less, the
development of the tubewell shall be considered incomplete and the Con-
tractor shall resume development of the tubewell at this own expense
until such time as the tubewell will produce water meeting the sand content
tolerances. Sand content determinations, water level, and discharge
measurements during the remainder of the one-hour sand test period
shall be made as directed by the Engineer.

(3) When the sand test has been satisfactorily completed, the
tubewell shall be further developed for 4 hours at 150 percent of the rated
capacity of the tubewell by surging and backwashing with the test pump
at five- to ten-minute intervals. Following the development period, the
tubewell shall again be pumped for a period of one hour at 150 percent
of design capacity during which time the sand test shall be repeated. The
specific capacity of the tubewell shall be determined from the water level
measurements and flow rates obtained during the pumping periods. If the
specific capacity obtained from the second pump test is found to be more
than 10 percent greater than that obtained in the first pump test, the de-
velopment shall be considered to be incomplete and the Contractor shall
resume development, at his own expense, until the tubewell is developed
sufficiently to meet this requirement.

(4) Upon satisfactory completion of the above 1-hour pumping period
the tubewell shall be permitted to recover for a period of one hour. Upon
the completion of this recovery period, a four-hour multiple step pump
test shall be performed by pumping the tubewell for one hour at each of
approximately four equal increments. The last increment shall be at 150
percent of rated capacity. Following this last increment of the step test,
the tubewell shall be pumped at a rate of 150 percent of design capacity
for a period of two hours.

(5) The following is a short summary of the development and
testing procedure:

(6) The Contractor sha!l furnish all necessary equipment for testing
the tubewell, including a water-i .bricated or oil-lubricated test pump capable
of delivering at least 150 perceT:n of the tubewell rated capacity at all stages
of the tests, a valve for fine adjustment of the discharge, an electric measuring
device to determine the drawdowna during each stage of the test, conductivity
meters for determining water quality, and Imhoff cones to measure sand content.
If oil-lubricated test pumps are used, the Contractor shall exercise all
reasonable precautions to keep the leakage of lubricating oil into the tubewell
at a minimum and shall promptly remove all oil which collects on the water
surface in the tubewell by the addition of detergents or other suitable chemicals
and pumping the emulsified oil from the tubewell. In the event the Contractor
fails to keep the leakage of oil into the tubewell within acceptable limits or to
promptly remove oil accumulations from the tubewell, the Engineer will order
the use of oil-lubricated test pumps discontinued, and the Contractor will be
restricted to the use of water-lubricated pumps for testing of the tubewells.
The actual depth of setting for the test pump will be determined by the Engineer
after the tubewell has been developed. Piping, gauges, orifices, meters, weir
boxes or other measuring devices shall be furnished, installed and removed
by the Contractor and shall remain his property. All measuring devices and
testing equipment will be subject to approval by the Engineer.

(7) The Contractor shall take drawdown and discharge measurements
and other pertinent data during each test at intervals as specified by the
Engineer. All such data shall be recorded on forms approved by the Engineer,
and the original of such forms shall be delivered to the Engineer at the com-
pletion of the development and testing operations.


4. 15 Sterilization and Sealing.

(1) After development and testing of the tubewell has been satisfactorily
completed, and when approved by the Engineer, the Contractor shall sterilize
the tubewell by dispersing copper sulfate (Cu SO4. 5 HZO) at the rate of two pounds
of copper sulfate per 100 feet of bore hole throughout the entire depth of the
tubewell. The procedure and equipment used to introduce and disperse the
copper sulfate in the tubewell shall be at the option of the Contractor, and shall
be approved by the Engineer.

(2) Upon completion of sterilization of the tubewell the Contractor
shall seal the tubewell with a --inch thick steel plate cap welded to the pump
housing casing around its full circumference, or by some other method ap-
proved by the Engineer. Compliance with this requirement will not relieve
the Contractor of his responsibility for the safeguarding of any part of the
tubewell completed until the Certificate of Acceptance is issued for the entire
tubewell installation.

5. 7 Aggregates.

(1) All sand and coarse aggregate for concrete, and sand for mortar
and grout shall be furnished by the Contractor and may be obtained by the
Contractor from any approved source.

(2) The term "sand" is used to designate aggregate in which the
maximum size of particles is 3/16 of an inch. Sand for concrete, mortar
and grout shall be either natural or manufactured sand, or a mixture of
natural sand and manufactured sand, provided that the manufactured sand
meets all the requirements set forth for natural sand. The sand, as delivered
to the watching plant, shall have a reasonably uniform and stable moisture
content. All operations for blending natural sand and manufactured sand will
be subject to the approval of the Engineer at all times.

(3) The sand shall consist of hard, dense, durable, uncoated rock

cl~u




CONCRETE


The air-entraining agent will be subject to sampling and testing by the Engineer.
The amount of air-entraining agent used shall be such as will effect the en-
trainment of from 4 to not more than 6 percent of air, by volume, in the con-
crete as discharged from the mixer. The agent shall be added to the batch in
solution in a portion of the mixing water.


5. 10 Composition of Concrete.

(1) Concrete shall be composed of Portland cement, sand, coarse
aggregate, water and if desired by the Contractor, an air-entraining agent,
all well-mixed and brought to the proper consistency. All concrete shall
develop a compressive strength at 28 days of not less than 2,000 pounds per
square inch. The proportions of the various ingredients shall be as deter-
mined by the Engineer from time to time during the progress of the work and
as tests are made of samples of the aggregate and the resulting concrete. The
mix proportions and appropriate water-cement ratio will be determined on the
basis of the production of concrete having suitable workability, density, im-
permeability, durability, and required strength, without the use of an excessive
amount of cement. All concrete shall have a minimum cement content of five
cubic feet of cement per cubic yard of concrete. The net water-cement ratio
of the concrete (exclusive of water within or absorbed by the aggregates) shall
not exceed 0. 60 by weight.

(2) Tests of the concrete will be made by the Engineer and the mix
proportions shall be changed whenever necessary for the purpose of securing
the required workability, density, impermeability, durability or strength,
and the Contractor shall be entitled to no additional compensation because of
such changes. The compressive strength of the concrete will be determined
by the Engineer by means of tests of 6-inch by 12-inch cylinders.

(3) The amount of water used in the concrete shall be changed as re-
quired to secure concrete of the proper consistency and to adjust for any varia-
tion in the moisture content or grading of the aggregates as they enter the
mixer. Addition of water to compensate for stiffening of the concrete resulting
from excessive overmixing or objectionable drying before placing will not be
permitted. Uniformity in concrete consistency from batch to batch will be re-
quired. The slump of the concrete, after the concrete has been deposited but
before it has been consolidated, shall not exceed three inches for all concrete.


5. 11 Batching of Concrete.

(1) The Contractor shall provide such means and equipment as are
required to determine accurately and to control the amount of each separate
ingredient entering the concrete. Such means, the equipment and its operation
shall at all times be subject to approval by the Engineer. The amounts of

3-31-65 STD

F-6




CONCRETE


cement, water, sand, and eachasize of coarse aggregate entering each batch
of concrete shall be determined by weighing or by volumetric measurement.
Where sacked cement is used, the concrete shall be proportioned on the basis
of integral sacks of cement, weighing 112 pounds per sack.


5. 12 Mixing Concrete.

(1) The concrete ingredients shall be mixed in a batch mixer for not
less than 1-1/2 minutes after all ingredients, except the full amount of water,
are in the mixer. The Engineer reserves the right to increase the mixing
time when the charging and mixing operations fail to produce a concrete batch
throughout which the ingredients are uniformly distributed and the consistency
is uniform. The concrete shall be uniform in composition and consistency
from batch to batch except when changes in composition or consistency are
required. Water shall be added prior to, during, and following the mixer-
charger operations. Excessive overmixing requiring the addition of water to
preserve the required concrete consistency will not be permitted.


5. 13 Form Construction.

(1) Forms to confine the concrete and shape it to the required lines
shall be used wherever necessary. Forms shall be of smooth planed boards,
in good condition. Suitable and effective means shall be provided in the con-
struction of all forms for holding adjacent edges and ends of panels tightly
together and in accurate alignment so as to prevent the formation of ridges,
fins, offsets, or similar surface defects in the finished concrete. All forms
shall be properly secured in position so as to prevent floating, or other move-
ment, during the placing of concrete.


5. 14 Placing Concrete.

(1) No concrete shall be placed until all formwork, reinforcement,
installation of parts to be embedded, bracing of forms, and preparation of
surfaces involved in the placing have been approved. No concrete shall be
placed in water. Immediately before placing concrete, all surfaces upon or
against which the concrete is to placed shall be free from standing water,
mud, debris or loose material. The surfaces of the ground or of other
absorptive materials against or upon which concrete is to be placed shall be
moistened thoroughly so that moisture will not be drawn from the freshly
placed concrete. The surfaces of all contraction joints shall be cleaned
thoroughly of accretions of concrete or other foreign material.

(2) The method and equipment used for transporting concrete shall
be such that concrete having the required composition and consistency will
be delivered to the work, without objectionable segregation or loss of slump.

CONCRETE


(3) Concrete shall be placed only in the presence of the Engineer.
In placing concrete against formed contraction joints, special precautions
shall be taken to ensure that the new concrete is brought into intimate contact
with the surface of the joint, by careful puddling and spading with the aid of
suitable tools. Re-tempering of concrete will not be permitted. Any concrete
which has become so stiff that proper placing cannot be assured shall be
wasted and no payment will be due the Contractor for such wasted concrete,
including the cement.

(4) Concrete shall be deposited in all cases as nearly as practicable
directly in its final position and shall not be caused to flow in a manner to
permit or cause segregation. Excessive separation of coarse aggregate in
concrete, caused by allowing the concrete to fall freely from too great a
height, or at too great an angle from the vertical or to strike the forms or
reinforcement steel, will not be permitted. After depositing, the concrete
shall be thoroughly consolidated around reinforcement and other embedded
materials and against all surfaces and into corners of the forms by rodding,
spading, vibrating or other approved means.

(5) Concrete shall not be placed during rains sufficiently heavy or
prolonged to wash mortar from coarse aggregate. Once placement of
concrete has commenced in a structure, placement shall not be interrupted
by diverting the placing equipment to other uses. The temperature of
concrete when it is being placed shall be not more than 90 degrees and not
less than 40 degrees Fahrenheit.

(6) Prior to placing of concrete in the pump pedestal, the outside of the portion
of the pump housing casing extending into the pump pedestal shall be covered with a heavy
coating of a cold-application bituminous mastic type concrete joint sealer or similar substance
approved by the Engineer to prevent bond between the pump house casing and the pump
pedestal. Where welds or other surface protrusions exist in the portion of pump housing casing
to be encased in concrete, the outside of the casing shall first be wrapped with roofing paper
cemented to the casing to form a smooth cylindrical surface which shall then be covered with
the approved bond-preventing coating.

(7) The time and method of removal and moving of forms shall be as
directed by the Engineer, and this work shall be done with care so as to
avoid injury to the concrete. No loading on green concrete will be permitted.
As soon as the forms are removed, the surface of the concrete shall be care-
fully examined, and any irregularities in the surface shall be repaired to the
satisfaction of the Engineer.


5. 15 Curing.

(1) All concrete shall be cured by either water curing or by mem-
brane curing as hereinafter specified. Membrane curing shall be used for
curing of all concrete, unless otherwise directed by the Engineer, except
that construction joints shall be cured only by water curing.

CONCRETE


(2) Concrete cured with water shall be kept wet for at least 14
consecutive days immediately following placement of the concrete, by covering
with water-saturated material, or by a system of perforated pipes, mechan-
ical sprinklers, or porous hose, or by any other approved method, which will
keep all surfaces to be cured continuously (not periodically) wet. Water used
for curing shall meet the requirements of these Specifications for water used
for mixing concrete.


(3) Membrane curing shall consist of the application of a white-
pigmented sealing compound which forms a water-retaining membrane on the
surface of the concrete. The sealing compound shall conform to the United
States Bureau of Reclamation "Specifications for Sealing Compound for Curing
Concrete", effective June 1, 1961. At the time of use, the sealing compound
shall be in a thoroughly stirred condition such that the pigment is uniformly
dispersed throughout the vehicle.


5. 16 Finishing.

(1) Finishing of concrete surfaces shall be performed only by skilled
workmen and in the presence of the Engineer. Formed surfaces upon or
against which backfill or concrete is to be placed will require no treatment
after form removal except for the removal and repair of defective concrete
and for the specified curing. Unformed surfaces that will be covered by
backfill or by concrete shall be finished by sufficient leveling and screeding
to produce an even, uniform surface.

(2) A hard steel trowel finish shall be applied to unformed surfaces
that will be exposed or subjected to the action of flowing water. Floating
and troweling shall be started as soon as the screeded surface has stiffened
sufficiently, and shall be the minimum necessary to produce a surface that
is free from screed marks and is uniform in texture.


5. 17 Joints.

(1) The location of all construction joints will be subject to the approval
of the Engineer. Contraction joints shall be constructed where shown on the
Drawings. The joints shall be made by'forming the concrete on one side of the
joint and allowing it to set before concrete is placed on the other side of the
joint. The surface of the concrete first placed at contraction joints shall be
coated with curing sealing compound before the concrete on the other side of
the joint is placed.
