quired to guarantee to discover water or to produce any given rate of flow of
water from any tubewell drilled on any site selected by the Authority.
2. 2 Intent of Contract Documents.
(1) The Contract Documents are intended to cover all the work to be
done. Any and all labor and materials not specifically stated in the Contract
Documents, but which are necessary to complete any part of the work in an
acceptable and workmanlike manner, shall be furnished by the Contractor,
and the cost of all such work shall be considered to be included in the Tender
(2) All deviations and exceptions to the Contract Documents, and
specifically to the Specifications for Procurement of Permanent Equipment

understood and agreed that the Contractor accepts and complies in every
respect with the requirements of the Contract Documents, that no further
deviations or exceptions will be permitted or accepted, and that all work
required to complete the Works is included in the Contract.
2.3 Laws, Rules, and Regulations
(1) The Contractor is assumed to be familiar with, and at all times
shall observe and comply with, all laws of the Government of Pakistan and
local governing bodies that in any manner may affect, control, limit, or
apply to the operations and conduct of the Contractor. The Contractor shall
be considered as the employer of all personnel whose services he uses in
carrying out the work and shall be obligated to comply with all of the
provisions of labor legislation in effect or which may be promulgated by the
Government during the course of the work.
2.4 Time of Contract
(1) The Time of Completion of the Contract shall be the number of
calendar days specified in the Special Stipulations hereof following the
"Date of Contract", which date shall be defined in the Contract Agreement.
The Contractor shall complete all work under the Contract within the number
of calendar days specified in the Special Stipulations, or within such
extended period of time as may be granted in accordance with the provisions
(2) The Contractor will be considered as having taken into account
when submitting his Tender, all hindrances and delays incidental to such
work, whether growing out of delays in securing materials or workmen or

prosecution of the work; by failure to provide advance of funds and letters
of credit within the specified time period; by delay authorized by the Engineer
pending arbitration on specifications or materials; or by any cause which the
Engineer may decide justifies the delay, then the time of completion will
be extended for such reasonable time as the Engineer may decide. In case
of unavailability of railway wagons for transport of gravel shrouding, cement,
or other materials or equipment, which results in delaying the progress of the
work, the Engineer may grant an extension of time, provided that.the Contractor
satisfies the Engineer that in spite of all reasonable measures the Contractor
was not able to obtain the necessary number of wagons.
(4) No extension of time will be granted the Contractor for delays
resulting from suspension of work when such suspension was made because
of failure on the Contractor's part to conform to the requirements of the
Contract Documents and the orders of the Engineer or for any delay occurring

of the work as decided by the Engineer. Request for extension of time shall be
given in writing to the Engineer as soon as reasonably possible, but not later
than 10 days following the occurrence of the cause of delay. The Engineer, if
he agrees to the extension of time, will confirm the same in writing to the
Contractor. The period of extension in the completion time shall not exceed
the actual period of delay caused by the "force majeure".
(2) 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
(3) If an unavoidable delay due to reasons of "force majeure" con-

DESCRIPTION OF PROJECT AND WORE
3.1 Location of Project
(1) The Marala-Ravi 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 Mountains to the Arabian Sea. Topographically the valley is
virtually flat, having a gentle slope of about one foot per mile in
the direction of the flow of 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
constructed, is irrigated by some of the largest irrigation systems
in the world. i
(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 subdivided into a number of individual
project areas. The Marala-Ravi Unit extends over an area of about
195,000 acres in Upper Rechna Doab between the Marala-Ravi and B.R.B.D.
Link Canals. The general location of the Area is shown on the Drawings
included in the Contract Documents. Most of the lands embodied in
the Marala-Ravi Unit area are now irrigated with canal water supplied
by the canal system offtaking from the Marala-Ravi.Link as shown on
the Drawings. In general, the tubewella 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 Marala-Ravi Unit area is situated at elevations varying
from approximately 750 to 800 feet above sea level. The climate is hot,
except during the winter months of November to February. Annual
precipitation varies from an "-e e # of approximately 37 inches in the
vicinity of Sialkot to 22 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.
(2) Temperature and precipitation data recorded at the weather
stations at Lahore and Sialkot are indicated in the following table :
TEMPERATURE AND RAINFALL DATA
(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
layers or lenses of silt and clay. Within the areas where the tube-
wells 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.
(2) The Authority does not guarantee that the material i-ll be
as described herein, nor the correctness of any interpretations, deduc-
tions, or conclusions indicated relative to subsurface conditions.
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.
(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. Following completion of the drilling
operation, an electric log may be made of a number of the tubewells as
req esti4:bythq Engineer.
(3) Upon the completion of drilling,blank and slotted fiberglass
tubewell casing sections, either 8 or 10 inches in diameter, are to be
placed 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 i16 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 wat4r 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 electrical equipment to the power
source, and construction of facilities to convey water from the outlet
of the discharge box to its point of use are not a part of this
3.6 Number and sizes of Tubewelle
(1) The capacities of individual tubewells will vary from one 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 60 to 70 feet below ground surface.
Pump Total Head will vary fror approximately 50 to 60 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 :

DRILLING OF TUBEWELLS
4. 1 General.
(1) Drilling of tubewells shall consist of all work required in connec-
tion with drilling the bore hole at each designated site as specified herein and
on the Drawings or as directed by the Engineer, including, but not limited to,
moving in, setting up, preparing the site, drilling the bore hole, collecting
data and keeping records, making electric logs of bore holes designated
by the Engineer, installing and removing temporary casing, dismantling,
moving out and cleaning up.
(2) Measurement for drilling of tubewells will be made of the actual
depth of each bore hole drilled, measured from the original ground surface,
for the depth of bore hole specified by the Engineer. No measurement will be
made of overdrilling required because of sloughing, caving ground or for the
Contractor's use in setting casing; for tubewells abandoned due to jammed
tools, caving ground, or negligence on the part of the Contractor; or for
tubewells not constructed in accordance with all of the requirements of these
Specifications. Measurement for electric logs will be made of the number
of complete logs actually made at the direction of the Engineer.
4. 2 Drilling.
(1) The Contractor shall drill each bore hole at the location estab-
lished in the field by the Engineer. The Contractor shall prepare the site
for the construction of the tubewell and shall provide for the disposal of
water, cuttings, and refuse from his operations away from the tubewell.
(2) The bore hole shall be drilled by the reverse circulation rotary
method with a minimum drill bit diameter of 22 inches. Each bore hole
shall be drilled to the depth specified by the Engineer. It is anticipated that
the depth of tubewells will vary; however, no minimum depth for any individual
tubewell or average depth for all tubewells is guaranteed. The bore holes
shall be drilled sufficiently straight and plumb so that the pump and tubewell
casing may be installed concentric with the hole and within the tolerance
specified for plumbness of the casing. Waste materials from the drilling
operation shall be disposed of in a manner approved by the Engineer.
(3) The Contractor shall be responsible for protecting the tubewells
from contamination by foreign material until the completed tubewell and
appurtenant facilities are accepted by the Engineer. The Contractor shall
bear any expense that may result from damage to any tubewell, tools,
or equipment that may be caused by caving, washing, or other distur-
bances within the tubewell.
(4) Where necessary to prevent sloughing and caving of surface
material, the Contractor shall furnish and install a conductor casing with
a minimum diameter 2 inches greater than the bit diameter from not
less than 6 inches above the ground surface to a sufficient depth to encounter
firm material. The conductor casing shall be new or used pipe of adequate
strength for the purpose. After the drilling is completed, the conductor
casing shall be removed by the Contractor and shall remain his property.
(5) If unstable material is encountered in drilling, the Contractor
shall stabilize the material in a manner approved by the Engineer. The use
of drilling fluid additives or other suitable materials may be employed in
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
(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.
(2) Representative ditch samples or cuttings of the material pene-
trated shall be taken at each change in lithology encountered and from each
10 feet of depth of the bore hole. Special care shall be exercised to determine
the thickness and location of each change in material encountered and to
obtain satisfactory samples. Immediately upon taking each sample, the
sample shall be placed in a cloth bag, partitioned wooden box, or other
approved container, properly marked for identification, and plainly labeled
with the depth of the top and bottom of the section of the bore hole repre-
sented. The containers shall be furnished by the Contractor. The method
of obtaining, processing, and storing the samples will be subject to approval
by the Engineer. The Contractor shall deliver all samples to the Engineer
at the site of the tubewell, except that when requested to do so by the Engineer,
the Contractor shall deliver specified samples to the Engineer's field head-
4. 4 Electric Logs.
(1) An electric log shall be made by the Contractor of a number of
bore holes as designated by the Engineer. The number of bore holes to be
logged will be determined in the field by the Engineer, and prior to the be-

stalling all pump housing and tubewell casing, including concentric reducers.
(2) Measurement for installation of casing will be made of the total
length of each size, wall thickness and type of pump housing and tubewell
casing actually installed in the tubewell, including length of concentric
reducers. The measurement of length will be taken from the elevation of the
top of the pump housing casing to the bottom of the tubewell casing. For
measurement of length, concentric reducers will be considered as casing
of the larger size to which the reducers are directly connected. No measure-
ment will be made of centralizers, bail plugs or other accessories required
for the complete installation.

4. 8 Installation.
(1) The Contractor shall install the entire pump housing and tubewell
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.
(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 consist of suitably designed fiberglass lugs on the
fiberglass couplings or wooden blocks of suitable design either cemented or
otherwise attached to the pipe or couplings in a manner that ensures that the
pipe is accurately centered in the drill hole. The detail design of centralizers
and the method of attachment to the pipe and 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
(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
the pump housing casing. The plumb shall hang vertically and shall be sus-
pended in the center of the pump housing casing from a point 10 feet above
the top of the casing. When the plumb is lowered to the bottom of the pump
housing casing, the line from which the plumb is suspended shall not deviate
from the center of the pump housing casing at the top by more than that
corresponding to a deviation of the plumb of 1-1/2 inches at the bottom of
the pump housing casing. All deviations shall refer to a vertical line passing
through the center of the pump housing casing at the top of the pump housing
(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
letter and number designation of the tubewell on that portion of the pump
housing casing which projects above the ground surface. All paint, brushes,
stencils and other materials required shall be furnished by the Contractor.
The characters shall be not less than six inches high, shall be painted with
lines one inch wide, and shall be positioned on the casing in accordance with
the Engineer's instructions.

uncased length of bore hole drilled at the direction of the Engineer as speci-
fied herein and on the Drawings including, but not limited to, developing the
source, excavating, stockpiling, grading, washing, storing, shipping, and
installing gravel shrouding in each tubewell.
(2) Measurement for gravel shrouding will be made of the depth of
the gravel shrouding actually furnished and placed in the tubewell, measured
from the ground surface to the depth of the bore hole requested by the Engineer.
If the entire length of the bore hole specified to be drilled by the Engineer is not
cased, the Contractor will be paid 1. 15 times the unit price bid per linear foot
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 railhead.
(2) The site is generally 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.
(4) The results of the explorations and investigations indicated
above are furnished for information only, and the Authority will not be re-
sponsible for any deduction, interpretation, or conclusion drawn therefrom
by the Contractor. Neither will the Authority be responsible for the amount
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
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 Engineerts 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
(2) The Contractor shall furnish all gravel used for shrouding which
shall be clean, hard, well-rounded, washed, carbonate free, and water worn,
without thin, flat particles and with the following gradations:

No. 16 0-5
(3) The method of placing the gravel and the equipment used will be
subject to approval by the Engineer. The Contractor shall circulate water
in the tubewell, as the gravel is being placed, by lowering the drill pipe
inside the casing and operating the circulation pump. The gravel shall be
placed to the top of the tubewell and shall be finally settled by bailing after
all gravel has been placed. The top of the gravel shrouding shall be main-
tained at the ground level at all times during developing, testing, and pumping.
Gravel and gravel placement not meeting these requirements will be subject to
rejection by the Engineer, and all gravel so rejected shall be replaced by the
Contractor at his own expense at no additional cost to the Authority.
(4) Temporary casing, if used, shall be carefully withdrawn in 5-
to 10-foot stages during placement of the gravel shrouding and the gravel shall
be introduced so that each stage of the hole above the bottom of the casing is
completely filled before the casing is withdrawn to the next stage. The process
of withdrawing the temporary casing shall be continued until the bottom of the
temporary casing is at least 10 feet above the top of the tubewell casing. Above
this point the temporary casing may be removed or left in place, at the option
of the Contractor, provided that no payment will be made to the. Contractor for
temporary casing left in place.
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
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.
(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
Development time 6 hours (minimum)
Recovery 1 hour (minimum)
Pumping period 1 hour
Development 4 hours
Pumping period 1 hour
Recovery 1 hour (minimum)
Step pumping 4 hours
Pumping period 2 hours
(6) The Contractor shall furnish all necessary equipment for testing
the tubewell, including a water-lubricated or oil-lubricated test pump capable
of delivering at least 150 percent 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 drawdown 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 iubewell 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 S04. 5 HO0) 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 i-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 in stallation.

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.

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

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 lose of slump.
(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. Retempering 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) 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.
