GENERAL REQUIREMENTS
A. GENERAL. The specifications contain detail instructions and
descriptions a)vering the major items of materials, construction and
workmanship necessary for building and completing the various units
or elements of the project. The specifications are intended to be so
written that only first class materials, workmanship and finish of the
best grade and quality will result. The fact that these specifications
may fail to be so complete as to cover all details will not relieve the
Contractor of full responsibility for providing a completed project of
high quality, first class finish and appearance and satisfactory for
operation, all within the apparent intent of the plans and specifications.
B. MATERIALS These specifications are intended to be so written
that only materials of the beat quality and grade will be furnished.
The fact that the specifications may fail to be sufficiently complete
in some detail will not relieve the Contractor of full responsibility
for providing materials of high quality. The specifications for
materials set out the minimum standard of quality which the Owner believes
necessary to produce a satisfactory project. No substitutions will be
permitted unless the Contractor has received written permission of the
Engineer to make a substitution for the material which has been specified.
Where the term "Or Equal" or "or Approved Equal" is used, it is
understood that if a material, product or piece of equipment bearing the
name so used is furnished, it will be approvable as the particular trade-
name was used for the purpose of establishing a standard of quality
acceptable to the Owner. If a product of any other name is proposed for
use, the Engineer's approval thereof must be obtained before the pro-
posed substitute is procured by the Contractor. Wherever the term "or
Equal" is used, it is understood to mean "Or Approved Equal".
The manufacturer of each item of material and/or equipment
shall furnish the Owner with a sworn statement that all material furnished by
him under this contract complies with these specifications and all
applicable A.S.T.M., A.S.A,, and Federal Specifications as set forth
herein.
C. MANUFACTURER'S QUALIFICATIONS All material and equipment
furnished under this contract shall be the product of manufacturers who
are known to be skilled and who have been regularly engaged for a period
of five years or more in the manufacture of each specific type of equip-
ment, or its counterpart.
D. CHANGE OF LOCATION No change in the Alignment is contemplated.
However, should a change be necessary due to difficulty in right-of-way,
or other reasona, the Owner reserves the right to make such change.
Unless it can be clearly shown that such change works an undue hardship on
the Contractor, no extra compensation will be allowed the Contractor,
except as provided by unit prices applicable to such changes,
-5-
E. WORKMANSHIP These specifications contain detail instructions
and descriptions covering the major items of construction and workman-
ship necessary for building and completing the various units or elements
of the project. The specifications are intended to be so written that
only first class workmanship and finish of the best grade and quality will
result. The fact that these specifications may fail to be so complete
as to cover all details will not relieve the Contractor of full responsi-
bility for providing a completed project of nigh quality, first class
finish and appearance, and satisfactory for operation, all within the
apparent intent of the plane and specifications.
P. CLEARING AND GRUBBING The Contractor shall do all clearing and
grubbing necessary for construction operations. All trees, branches, limbs
and roots shall be removed and disposed of by the Contractor so as to
eliminate the possibility of starting a grass fire.
G. FENCES Where it is necessary for the Contractor to cut fences,
such fences shall be protected, repaired and replaced by the Contractor
in u condition equal to, or better than, the original condition. Cuts
in fences shall be made in a neat and workmanlike manner and the Con-
tractor shall be responsible for prevention of loss of stock, or pets
• through gates, breaks or gaps in fences due to construction operations.

price items under Section 5 "Measurement and Payment". If the amount of work
is increased, and the work can fairly be classified under the specifications,

be done and material to be furnished hereunder. Where the estimated
quantities are shown for the various classes of work to be done and
material to be furnished under this Contract, they are approximate
and are to be used only as a basis for estimating the probable cost
of the work and for comparing the proposals offered for the work.
It is understood and agreed that the actual amount of work to be
done and material to be furnished under this contract may differ

be relieved of the obligation to fully complete the work and,
thereupon, the Contractor shall receive payment of the balance due

prior use increases the cost of or delays the work, the Contractor
shall be entitled to such extra compensation, or extension of time,
or both, as the Engineer may determine.
5.06 FINAL COMPLETION AND ACCEPTANCE: Within ten (10) days after
the Contractor has given the Engineer Written notice that the work
has been completed, or substantially completed, the Engineer and
the Owner shall inspect the work and within said time, if the work
be found to be completed or substantially completed in accordance
with the Contract Documents, the Engineer shall issue to the owner
and the Contractor his Certificate of Completion, and thereupon it
shall be the duty of the Owner within the ten (10) days to issue a
Certificate of Acceptance of the work to the Contractor.
5.07 FINAL PAYMENT; Upon the issuance of the Certificate of
Completion, the Engineer shall proceed to make final measurements
and prepare final statement of the value of all work performed and

accordance with the provisions of "Payments Withheld."
6. EXTRA WORM AND CLAIMS
6.01 EXTRA WORK: It is agreed that the Contractor shall perform all
Extra Work under the direction of the Engineer when presented with a
Written Work Order signed by the Engineer, subject however, to the
right of the Contractor to require a written confirmation of such Extra
- 15 -
Work Order by the Owner. It is also agreed that the compensation to
be paid the Contractor for performing said Extra Work shall be
determined by one or more of the following methods:
Method A - By agreed unit prices: or
Method B - By agreed lump sum; or
method C - If neither Method A nor Method B be agreed upon
before the Extra Work is commenced, then the
Contractor shall be paid the "actual field cost"
of the work, plus fifteen (15) percent.
In the event, said Extra Work be performed and paid for under
Method C. then the provisions of this paragraph shall apply and
the "actual field cost" is hereby defined to include the cost of all
workmen, such as foremen, timekeepers, mechanics and laborers, and
materials, supplies, teams, trucks, and rentals on machinery and
equipment, for the time actually employed or used on such Extra
Work, plus actual transportation charges necessarily incurred,
together with all power, fuel, lubricants, water, and similar
operating expenses, also all necessary incidentals expenses incurred
directly on account of such Extra Work, including Social Security,
Old Age Benefits and other payroll taxes, and a rateable proportion
of premiums on Performance and Payment Bonds, and Maintenance Bonds,
and on Public Liability and Property Damage, and Workmen's Compensa-
tion, and all other insurance as may be required by any law or ordinance,
or directed by the Engineer or owner, or by them agreed to, the Engineer
may direct the form in which accounts of the "actual field cost" shall
be kept and the records of these accounts shall be made available to the
Engineer. The Engineer may also specify in writing, before the work
commences, the method of doing the work and the type and kind of
machinery and equipment to be used; otherwise these matters shall be
determined by the Contractor. Unless otherwise agreed upon, the prices
for the use of machinery and equipment shall be determined by use of
100 per cent, unless otherwise specified, of the latest schedule of
Equipment Ownership Expense adopted by the Associated General Con-
tractors of America. Where practicable the terms and prices for the
use of machinery and equipment shall be incorporated in the Written
Extra Work Order. The fifteen (15X) percent of the "actual field cost"
to be paid the Contractor shall cover and compensate him for his
profit, overhead, general superintendence and field office expense, and
all other elements of cost and expense not embraced within the "actual
field cost" as hereindefined, save that where the Contractor's Camp
or Field Office must be maintained primarily on account of such Extra
Work: then the cost to maintain and operate the same shall be included
in the "actual field cost".
No claim for Extra Work of any kind will be allowed unless ordered
in writing by the Engineer. In case any orders or instructions,
16 -
either oral or written, appear to the Contractor to involve Extra
Work for which he should receive compensation or an adjustment in
the Construction time, he shall make written request to the Engineer
for written order authorizing such Extra Work. Should a difference
of opinion arise as to what does or does not constitute Extra Work,
or as to the payment therefor, and the Engineer insists upon its
performance, the Contractor shall proceed with the work ,after making
written request for written order and shall keep an accurate account
of the "actual field cost" thereof, as provided under Method C. The
Contractor will thereby preserve tha right to submit the mattar of
payment to arbitration, as hereinbelow provided.
6.02 TIME OF FILING CLAIMS: It is further agreed by both parties
hereto that all questions of dispute or adjustment presented by
the Ccntractor shall be in writing and filed with the Engineer
within thirty (30) days after the Engineer has given any directions,
order or ins ruction to which the Contractor desires to take exception.
The Engineer shall, within a reasonable time, reply to such written
exceptions by the Contractor and render his final decision in writing.
In case the Contractor should appeal from the Engineer's decision,
and demand for arbitration shall be filed with the Engineer and the
Owner in writing .•ithin ten (10) days after the date of delivery
to Contractor of the Engineer's final decision. It is further
agreed that final acceptance of the work by the Owner and the
acceptance by the Contractor of the final payment shall be a bar
to any claims by either party, except where noted otherwise in the
Contract Documents.
6.03 ARBITRATION: All questions of dispute under this Agreement
shall be submitted to arbitration at the request of either party
to the dispute. The parties may agree upon one arbiter; otherwise,
there shill be three, one named in writing by each party, and the
third chosen by the two arbiters so selected, or if the arbiters
fail to select a third within ten (10) days, he shall be chosen
by a District Judge serving the County in which the major portion
of the project is located, unless otherwise specified. Should the
party demanding arbitration fail to name an arbiter within ten (10)
days, the Engineer shall appoint such arbiter. Should either party
refuse or neglect to supply the arbiters with any papers or informa-
tion demanded in writing, the arbiters are empowered by both parties
to take separate preceedings.
The arbiters shall act with promptness. The decision of any two
say shall be binding on both parties to the contract. The decision of
the arbiters upon any question submitted to arbitration under this
contract shall be a condition prece4ent to any right of legal action.
The decision of the arbiter or arbiters may be filed in court to
carry it into effect.
The arbiters, if they deem the case demands it, are authorized to
17 -
award the party whose contention is sustained, such sums as they
deem proper for the time, expense and trouble incident to the appeal,
and if the appeal was taken without reasonable cause, they may award
damages for any delay occasioned thereby. The arbiters shall fix
their own compensation, unless otherwise provided by agreement,
and shall assess the cost and charges of the arbitration upon either
or both parties. The award of the arbiters must be made in writing.
7. ABANDONMENT Of CONTRACT
I
7.01 ABANDONMENT BY CONTRACTOR: In case the Contractor should
abandon and fail or refuse to resume work within ten (10) days
after written notification from the Owner, or the Engineer, or.if
the Contractor fails to comply with the others of the Engineer,
when such orders are consistent with the Contract Documents, then,
and in that case, where performance and payment bonds exist, the
Surety on the bonds shall be notified in writing and directed to
complete the work, and a copy of said notice shall be delivered
to the Contractor.
After receiving said notice of abandonment, the Contractor shall
not remove from the work any machinery, equipment, tools, materials,
or supplies then on the job, but the same, together with any materials
and equipment under contract for the work, may be held for use
on the work by the Owner or the Surety on the performance and payment
bonds, or another contractor in completion of the work; and the
Contractor shall not receive any rental or credit therefor (except
when used in connection with Extra Work, that where credit shall be
allowed as provided for under Section b, Extra Work and Claims),
it being understood that the use of such equipment and materials
will ultimately reduce the cost to complete the work and be reflected
in the final settlement.
Where there is no performance bond provided or in case the Surety
should fail to commence compliance with the notice of completion
hereinbefore provided for, within ten (10) days after service of
such notice, then the Cvner may provide for completion of the work
in either of the following elective manners:
7.011 The owner may thereupon employ such force of men and
use such machinery, equipment, tools, materials, and supplies as
said Owner may deem necessary to complete the work and charge the
expense of such labor, machinery, equipment, tools, materials, and
supplies to said Contractor, and expense so charged shall be deducted
and paid to by the owner out of such moneys as may be due, or that may
thereafter at any time become due to the Contractor under and by
virtue of this Agreement. In case such expense is less than the sum
which would have been payable under this contract if the same had been
18 -
' I
completed by the Contractor, then said Contractor shall receive the
difference. In case such expense is greater than the sum which would
have been payable under this contract if the same had been completed by
said Contractor, then the Contractor and/or his Surety shall pay the
amount of such excess to the Owwer; or
7.012 The owner, under sealed bids, after five (5) days
notice published one or more times in a newspaper having general
circulation in the county of the location of the work, may let
the contract for the completion of the work under substantially the
same terms and conditions which are provided in this contract. In
case of any increase in cost to the Owner under the new contract
as compared to what would have been the cost under this contract
such increase shall be charged to the Contractor and the Surety
shall be and remain bound therefor. However, should the cost to
complete any such new contract prove to be less than what would have
been the cost to complete under this contract, the Contractor
and/or his Surety shall be credited with the difference.
When the work shall have beep: substantially completed the Contractor
and his Surety shall be so notified and Certificatea, of Completion
and Acceptance, as provided in Paragraph 5.06 hereinabove, shall be
issued. A complete itemized statement of the contract amounts,
certified to by the Engineer as being correct, shall then be prepared
and delivered to the Contractor and his Surety, whereupon the
Contractor and/or his Surety, by said statement, within fifteen (15)
days after the date of such Certificate of Completion.
In the event, the statement of accounts shows that the cost to
complete the work is less than that which would have been the cost
to the Owner had the work been completed by the Contractor under
the terms of this Contract; or when the Contractor and/or his
Surety shall pay the balance shown to be due by them to the Owner,
then all machinery, equipment, tools, materials, or supplies left
on the site of work shall be turned over to the Contractor and/or
his Surety. Should the cost to complete the work exceed the con-
tract price, and the Contractor and/or his Surety fail to pay the
amount due the Owner within the time designated hereinabove, and
there remains any machinery, equipment, tools, materials, or supplies
on the site of work, notice thereof, together with an itemized
list of such equipment and materials, shall be mailed to the Con-
tractor and his Surety at the respective addresses designated in
this contract; provided, however, that actual written notice given
in any manner will satisfy this condition. After mailing, or other
giving of such notice, such property shall be held at the risk of
the Contractor and his Surety subject only to the duty of the
Owner to exercise ordinary care to protect such property. After
I
- 19 - •
I
fifteen 115) days from the date of said notice the Owner may sell
such machinery, equipment, tools, materials, or pupplies and apply
the net sum derived from such sale to the credit of the Contractor
and his Surety. Such sale may be made at either public or private
sales, with or without notice, as the Owner may elect. The Owner
shall release any machinery, equipment, tools, materials, or supplies,
which remain on the work and belong to persons other than the Contractor
or his Surety, to their proper owners. The books on all operations
provided herein shall be open to the Contractor and his Surety.
1.02 ABANDONMENT BY OWNER: In case the Owner shall fail to comply
with the terms of this Contract, and should fail or refuse to comply
with said terms within ten (10) days after written notification by
the Contractor, then the Contractor may suspend or wholly abandon
the work, and may remove therefor from all machinery, tools, and equip-
ment, and all materiels on the site of work that have not been
included in payments to the Contractor and have not been wrought
into the work. Aud thereupon, the Engineer shall make an estimate
of the total amount earned by the Contractor, which estimate shall
include the value of all work actually completed by said Contractor
(at the prices stated in the attached proposal where unit prices are
• used), the value of all partially completed work at a fair and
equitable price, and the amount of all Extra Work Performed at the
prices agreed upon, or provided for by the terms of this contract,
and a reasonable sum to cover the cost of any provisions made by
the Contractor to carry the whole work to completion and which
cannot be utilized. The Engineer shall then make a final statement
of the balance due the Contractor by deducting from the above
estimate all previous payments by the owner, and all other sums
that may be retained by the Owner under the terms of this Agreement,
and shall certify same to the Owner, who shall pay to the Contractor,
on or before thirty (30) days after the date of the notification by
the Contractor, the balance shown by said final statement as due the
Contractor under the terms of this agreement.

wise. All valves shall be equipped with a two (2) inch square wrench
nut for operations unless otherwise specified. Valves shall be designed
for a minimum working pressure of one hundred fifty (150 P.S.I.) pounds
per square inch and shall comply in all respects with the latest appli-
cable American Water Works Association Specifications. Valves (also
tapping sleeves and valves) shall be Mueller or equal. All valves shall
be installed as indicated on the plans. For each gate valve the Con-
tractor shall furnish and install a valve box.
Valve boxes shall be three piece screw type cast iron of the
extension type and shall be similar to Trinity Valley Iron and Steel
Company, No. 2291 or Mueller, No. H-10364. The three pieces shall
consist of the top section, bottom section, and cover. Extensions
shall be provided as required.
- 21 -
..a
Valves shall be carefully handled and lowered into position in such
a manner as to prevent damage to any parts of the valve. Valves shall be
placed in such positions as indicated on the plans with the stem in a
vertical position and securely held until all connections have been
made.
Gate valves sna pipe fittings shall be set and jointed to new
pipe in the manner herein specified for cleaning, laying, and jointing
pipe. Hub ended valves shall be jointed to pupe only with lead joints.
Flanged and mechanical joint valves will be preferred where suitable.

brushed thoroughly with a wire brush just prior to assembly.
This thorough brushing shall remove all loose rust or foreign
matter which may be present and provide a clear surface which shall
be brushed with soapy water gust prior to slipping the gasket over
the spigot end and iton the bell. Soapy water shall also be
brushed over the gasket prior to installation to remove loose
dirt and lubricate the gasket.
Size, Inches Range of Torque. Ft. Pounds
S/8 40 - 60
3/4 60 - 90
1 70 - 100
1-1/4 90 - 120
The above torque loads shall be applied with torque measuring
or indicating wrenches.
When tightening belts, the gland shall be brought up toward
the pipe flange evenly, maintaining approximately the same distance
between the gland and the face of the flange at all joints around the
socket. The bottom bolt shall be tightened first, then the top bolt,
next the bolt on either side and last, the remaining bolt. This cycle
shall be repeated until all bolts are within the above range or torques.
If effective sealing is not attained at the maximum torque, the joint
shall be disassembled and reassembled after through cleaning. Over-
stressing of bolts to compensate for poor installation will not be
allowed.
Deflection from a straight line or grade made necessary by
vertical or horizontal curvea or off-sets shall not exceed the following
limits:
-22-
Nominal Diameter of Pipe Length of Pipe Deflection
2 inches 16 feet 28 inches
6 inches 16 feet 24 inches

The deflection is the distance between the center lines extended
of any two connecting pipes.
H. LAYING PIPE After placing a length of pipe in the trench,
the yarning materials for the joint shall be held around the bottom
of the spigot so that it will enter the bell as the pipe is aboved
into position. The spigot shall be centered in the bell and the pipe
forced "home" and brought into true alignment. It shall be secured
there with earth carefully tamped under and on each side of it, except-
ing at the bell holes. Care shall be taken to prevent dirt from enter-
ing the joint space. No blocking up of the pipe or joints will be per-
mitted. Whenever it is necessary to deflect pipe from a straight line,
either in the vertical or horizontal plane, to make small angles in
alignment to avoid obstructions, to plumb stems, or for other reasons,
the degree of deflection shall not exceed that shown by the Handbook of the
Cast Iron Research Association.
Although the above section applies primarily to bell and spigot
pipe, all applicable portions apply as well to roll on and mechanical
joint pipe.
1. FIRE HYDRANTS Fire hydrants shall conform to Smerican Water
Works Association Specifications, C-502-54. Hydrants will have a five
anri one-forth (5k) inch valve opening and two, two and one-half (2h)
inch steamer connections. All hydrants will be of the dry top type with
"0" ring packing and shall have a compression type main valve that closes
with the pressure. A one and one-forth (1k) inch pentagon operating nut
shall open to the left. Each hydrant will be preceeded by a gate valve.
Fire hydrants shall be Mueller (A24015) (Traffic Model).
SETTING FIRE HYDRANTS. GATE VALVES. AND SERVICE BOXES Fire
hydrants, gate valves and valve boxes installed in trenches, shall be
placed where required. They shall be set plumb and the valve boxes
shall be directly over the valves. After being correctly positioned,
earth fill shall be carefully tamped around the service box for a
die- Lance of four feet on all sides of the box. Each service box shall
be set in a concrete pad, two feet square mad eight inches thick at
ground elevation or as Airected by the City of Denton. Fire hydrants
shall be set at such elevations that the connecting pipe and the distri-
bution mains shall have the same depth of cover. Each fire hydrant
shall be placed upon a slab of concrete not leas than four inches thick
and fifteen inches square. The backside of the fire hydrant opposite
the pipe connection, shall be blocked with concrete to prevent the fire
hydrant from blowing off the line. Care must be taken in placing of
the concrete not to block the weep holes at the bottom of the fire hydrant.
Around the base of each fire hydrant shall be placed not leas than seven
s - 23 -
cubic feet of broken stone or loose gravel and rock to insure the com-
plete drainage of the fire hydrant when closed. All backfiil after
installing any fire hydrant shall be thoroughly compacted to tt,e surface
of the ground. Before installing any fire hydrant or gate valve, care
shall be taken to see that all foreign material is r:stmoved from the
barrel. Stuffing boxes shall be tightened and the fire hydrant or gate
valve opened and closed to see that all parts are in working condition.
J. SERVICE LINES AND TAPS Service line on Oak Street and McKinney
Street only will be tied to the new water line. A service tap shall be
made where designated on plans. The tap shall be a minimum of 3/4 inch
(or at specified), and shall be made by drilling and tapping the main for
the inslirtion of a corporation stop (Mueller H15000 or equal). The copper
service ripe shall be a minimum of thirty (30) inches below the finished
surface of the street. Double strap service clamps may be used for
larger taps if specified. No tap shall be made within less than
eighteen (18) inches of another tap. All taps shall be made on the
upper quadrants of the main at approximately forty-five degrees from
vertical. No taps will be made on the top of the pipe.
All service lines shall be run to a point approximately eighteen
(18) inches behind the curb line and shall be ended with the installation
of curb atop with a pipe thread outlet similar to Mueller #H 15215. All
service lines shall be of Type K, soft copper tubing with flared connections.
The service lines shall be tied into the existing meters. The meters
on Oak Street shall be moved back to a minimum distance of 24 feet from the
center line of the street.
K. EXCAVATION Trenches shall be excavated by a trenching machine
except in locations where hand trenching is required. The banks of
trenches shall be vertical.
Trenches will be excavated to the lines and grades laid out
by the Engineer or as shown on the plans.
The width of the trench shall be six (b) inches vinimum and
eight (8) inches maximum on each side of the pipe bell.
Trenches for water pipe shall be carried to a depth necessary
to obtain a minimum cover of three feet six inches (4211) over the pipe as
measured from the proposed street surface.
The excavation shall not advance more than five hundred (500)
feet ahead of the completed backfilled line. Pipe shall be laid in
all trenches that have been opened at the end of each day's work,
unless the Contractor secured written permission to do otherwise from
the Engineer.
24 -
s, ,
1. If the bottom of the trench becomes an undtable foundation
for the pipe through the neglect of the contractor to adequately
shore or dewater the trench, or if the
undisturbed material encountered at the grade depth constitutes,
in the opinion of the Engineer, an unstable
foundation for the pipe, the contractor will be required to
remove such unstable material and backfill the trench to
the proper grade with approved compacted gravel.
2. Also, if the trench is inadvertently excavated deeper than
necessary, it shall be backfilled to the proper grade with
approved compacted gravel at the contractor's expense.
The contractor shall remove any water which collects in the trenches
while water pipes are being laid. In no case shall water, be allowed to
run through the pipe. Water encountered shall be disposed of by the
contractor in a manner satisfactory to the Engineer.
The bottoms of the trenches for all pipe shall be carefully and
truly graded, formed and lined according to the grades and dimensions
furnished by the Engineer before any pipe is laid therein. Sell
holes shall be excavated by hand.
The contractor shall excavate all trenches, including work necessary
in working around existing pipe lines or other obstructions. The con-
tractor shall give notice to the owners of any such lines of obstructions
in order that they may have time to take the necessary precautio " for
protecting their protecting their property. The contractor shall be
responsible for protecting the owner from any damage from his operations
in such work.
In rock, excavation shall be carried four (4) inches below the
bottom of the pipe and loose earth or gravel, thoroughly tamped, shall
be used for backfilling to grade.
After testing and inspection of pipe lines have been finished on
any completed portion of the work the trench may be backfilled. Back-
filling shall be accomplished in compliance with the applicable portions
of these specifications.
L. BACKFILLING - Good sound earth from the spoil band shall be brought
up in hand or mechanical tamped layers not exceeding six (6) inches
in thickness of loose fill approximately equal on each aide of the pipe
to a height of 12 inches over the top of the pipe. The tamping shall be
done in such a manner as not to disturb the pipe from its original
position. The backfill material may need to be moistened to facilitate
compaction. This determination will be made by the Engineer.
- 25 -
1. BACKFILL FOR CROSSING LOCUST STREET AND BELL AVENUE (Type A) -
The backfill up to 12 incheb above the pipe shall be as
specified in the above Section L. From that point to two
inches below the pavement, the trench shall be brought up
in layers not exceeding eight inches loose fill of cement
stabilized road gravel. This road gravel must have a
P. I. of ten (10) or under and at least 8% Portland Cement
added to it by weight. Each layer shall be tamped with a
mechanical tamped and the material shall be moistened to
facilitate compaction and hydradation of the Cement. The
areas in which this backfill will be required are those
designated on the plans as Type A backfill. Surfacing
shall be as called for in the following section.
2. BACKFILL FOR ALL OTHER AREAS (TvDe B) - The backfill up to
12" above the pipe shall be as specified in Section L. The
remainder of the backfill material shall be placed loosely
in the trench up to the top of the ditch. The trench shall
then be thoroughly jetted with water under pressure until all
settlement has ceased. The trench shall then be mechanically
tamped with a hydro hammer. No rock greater than six (6)
inches in any direction may be placed in the final backfill.
After tamping a 12" layer of 2:27 pitrun sand and gravel,
and Portland Cement shall be placed in the ditch. This back-
fill shall be throughly tamped to achieve at least 95% of
standard proctor. As soon as possible, a two inch thickness
of hot mix surfacing conforming to Texas Highway Department
Specifications for Type D mix shall be placed where designated
on the plans. In concrete areas, a 6 inch thickness of
concrete shall be placed. The contractor shall keep all
ditches well maintained during construction filling all
depressions as they occur. In the areas on McKinney Street
and Oak Street marked for type C backfill the requirements
for the tamping of the ditch and the stabilized gravel
backfill will be waved.
M. CONNECTION TO EXISTING WATER MAINS
A. Description - Where indicated on the plans ,nd/or here-
inafter specified, the Contractor shall connect the new main with existing
mains or lines. This will be accomplished in the manner essentially
shown or specified. The Contractor shall furnish all labor, materials,
equipment, and services required for the locating and uncovering of the
existing lice, the making of cuts in the existing line, the removal,
relocation and/or lowering of existing lines as required, de-watering

All visible lea'ka at exposed joints and all leaks evident on
the surfaco and covered shall. be recaulked or reassembled and mini-
mized regar1less of f:he total leakage as shown by test.
All pipe, fittings and oth.r materials found to be defective
under test shall be removed and replaced at the contractor's expense
PEWSSABLE LEAKAGE No pipe installation will be accepted
until the leakage is less than the number of gallons per hour as
determined by the following formula:
ndv
Ln P
1,850
Where L equals the allowable leakage in gallons per hour;
H equals the number of joints in the length of pipe line tested;
D equals the nominal didmeter of the pipe in inches, and P equals
the average test pressure in pounds per square inch.
Based on this formula the permissible leakage per 100 pipe
joints per hour is as follows:

VARIATION FROM PERMISSIBLE LEAKAGE Should any test of pipe
in place disclose leakage greater than the specified, the contractor
shall at his own expense locate and repair the defective joints until
the leakage is within the specified allowance.
LEAKAGE DEFINED Leakage is defined as the quantity of water
supplied into the newly laid pipe, or any valved section of it,
necessary to maintain the specified leakage test pressure after the
pipe has been filled with water and the air expelled.
P. STERILIZATION OF WATER MAINS Each unit of completed water
line installed shall be thoroughly sterilized with chlorine or hypo-
cholrite before it is placed in operation. The amount of chlorine
applied shall be such as to provide a dosage of not less than fifty
(30) parts per million. The chlorination material shall be introduced
to the water line in such a manner as to distribute the chlorine to
throughout the oyster.. All valves in water lines being sterilized
shall be opened and closed several times during the twenty-four (24)
hour period. Following a contact period of not leas than twenty-four
(24) hours, the sterilizing solution shall be discharged from the
pipe and replaced with City Water direct from a City Main. A sample of
water from the sterilized main shall be taken (not through a fire
hydrant) from a suitable tap under the supervision of the Engineer or
his Inspector and submitted to the City Chemist or the State Health
Deportment for:analysis. If the test shows a satisfactory quality of
water, the line so sterilized may then be placed in service. If the
sample shows unsatisfactory quality of water, the process of steriliza-
tion shall be repeated until a satisfactory water is obtained.

and spigots home. Line and grade stakes will be provided by the Engineer.
C. Pipe Jointfa - General: Before laying each joint of pipe, the bell
and spigot rings shall be thoroughly cleaned by brushing and wiping. If
any damage to the protective costing on the metal has occurred, it will be
required of this Contractor to repair such damage before the pipe is laid.
The damaged areas shall be thoroughly cleaned and immediately following the
cleaning the metal shall be painted with the same material used originally
in the manufacture of the pipe.
Sections of pipe shall be tightly fitted together and care shall be
exercised to secure true alignment and grade. Where pipe is being laid
tae gasket shall be placed on the spigto ring and the spigot end of the
pipe shall then be entered into the bell of the adjoining pipe and forced
into position. The gasket and the inside surface of the bell shall be
lubricated with a suitable solution (flax soap) which will f%cilitate the
telescoping of the joint. The inside joint recess between ends of the
pipe sections shall have a maximum and minimum width of three-quarter inch
(3/411) and one'half inch respectively. No "Blocking up" of pipe or
joints will be permitted.
D. Interior Joints: Just prior to the making of the joint, the bell end
of the pipe shall be "butter" with sufficient grout to completely fill the
inside joint recess when the joint is made. The spigot shall then be
• telescoped into the bell. The interior shall be thoroughly swabbed and
cleaned. The concrete mortar shall consist of one part of cement to two

• of thick cream. The joint shell be filled with this grout from one side
in one continuous operation until the grout has flowed entirely around the
pipe. During the filling of the joint, it shall be nodded with flexible
wire to settle the grout.
F. Piotection of Exposed Metal: All exposed metal shall be protected
by a minimum one (1") inch coating of Portland Cement mortar consisting of
one part c#jrent and two parts sand. Exposed surfaces such as, but not limit-
ed to, flanges, caulked joints, threaded outlets, closures, etc., shall be
protected in this manner. Where necessary, coating shall be reinforced
with wire mesh.
The surface receiving a cement mortar coating shall be thoroughly
cleaned and wetted with water just prior to placing the Eement mortar
coating. After placement, care shall be taken to prevent cement mortar
from drying out too rapidly by covering with damp earth or burlap. Cement
mortar coating shall not be applied during freezing weather.
i
For large diameter flanges where it is impracticable to use a cement
mortar coating, and where directed by the Engineer, two (2) coats of "Bitu-
mastic 30' as manufactured by the Koppers Company, or approved equal, may be
used. "Bitmastic 30" shall be applied in accordance with the manufacturer's
recommendations.
G. Patch: Excessive patching of lining or coating will be permitted.
Patching of lining or coating will be allowed whe m area to be repaired
does not exceed 100 square inches And has no dimensions greater than 12
inches. In general, there shall not be more than one patch on either the
lining or the coating of any one joint of pipe.

SECTION VI -HYDROSTATIC TEST
A. General: After the water line has been 1'id and backfilled, each
• valve section of newly laid pipe shall be subjected to a hydrostatic
pressure test. For any section being tested, the pressure applied shall
be such that at the lowest point in the section, the pressure shall be
150 lbs. per square inch. Adjustments aserequired shall be made for
differential in elevation between the low point of the section being
tested and center line of pressure test gauge.
B. Duration of Test: The duration of each pressure test shall be four
(4) hours.
C. ProcedureTi-The Contractor may test the concrete cylinder pipe line in
sections when all the pipe in the section is at least 28 days old. The cast
iron pipe line and/or the asbestos-cement pipe line may be tested upon com-
pletion of backfilling and the "setting up" of concrete blocking. The
test shall be made against valves when available, or by placing temporary
bulkheads in the pipe, and filling the line +lowly with water. Cara shall
be used to see that all air vents are open during the filling. After the
line, or section thereof has been completely filled, it shall be allowed
to stand under a slight pressure for at least 48 hours to allow the
lining to absorb what water it will and to allow the escape of air from
any air pockets. During this period the bulkheads, valves, manholes and
connections shall be examined for leaks. If any are found these shall be
stopped or, in the case of valves in the main line of bulkheads, provision
shall be made for measureing the leakage during the. test. The water
necessary to maintain the test pressure shall be measured through a meter or
by other means satisfactory to the Engineer. Contractor shall furnish
all necessary equipment and make tests at his expense.
Before applying the specified test pressure, all air shall be expelled
from the pipe. In the event it is necessary to expell the air from high
points other than where air valves are provided, the Contractor may tap
the line for this purpose and afterwards tightly plug the tap. These
taps must be made by the pipe manufacturer. No extra compensation will
be made for these taps.
D. Easmination Under Pressure: During the last two hours of the teat,
the entire route of the pipe line shall be inspected to locate any leaks or
breaks. Any defective joints, cracked or defective pipe, fittings or valves
' discovered in consequence of this pressure test shall be removed and replaced
with sound material in the manner provided and the test shall be repeated
until satisfactory results are obtained.
Any and all noticeable leaks shall be repaired regardless of whether
the actual leakage is within the allowable.
- 38 •
E. Permissible Leakage: No pipe installation will be accepted until
or unless the leakage, as determined by this Hydrostatic Test, is with the
allowances set forth in the tabulation below:
Pipe Size Allowable Leakage per 100 Joints

12" 7.94
16" 10.59
18" 11.92
20" 13.24
F. Variation from Permissible Leakage: Should any test of pipe laid dis-
close leakage greater than that specified, the Contractor shall at his own
expense locate and repair the defective points until the leakage is within
the specified allowable.
G. Leakage Defined: Leakage is defined as the quantity of water to
be supplied into the newly laid pipe, or any valved section of it, necessary
to maintain the specified leakage test pressure after the pipe has been
filled with water and the air expelled.
