8.01 Notification of Contractor. If the Contractor
should abandon and fail to refuse to resume work
within 10 days after written notification from the
Owner when such orders are consistent with this

attached, then the Contractor shall be deemed as
having abandoned the Contract. In such event the
Surety on the bond shall be notified in writing
and directed to complete the work, and a copy of
said notice shall be delivered to the Contractor.
8.02 Retention of Contractor's Equipment and Materials
by Owner. After receiving said notice 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 Bond or
another contractor in completion of the work; and
20
the Contractor shall not receive any rental or
credit therefor except when used in connection
with extra work where credit shall be allowed as
provided for under Section 1.04 "Extra Work ", it
being understood that the use of such equipment
and materials will ultimately reduce the cost to
complete the work and will be reflected in the
final settlement.
8.03 Methods of Completing the Work. If the Surety
should fail to commence compliance with the notice
for completion hereinbefore provided within 10
days after service of such notice, then the Owner
may provide for completion of the work in either
of the following elective manners:
a. The Owner may thereupon employ such force of
workers 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 the expense so charged
shall be deducted and paid by the Owner out
of such monies as may be due or that may
thereafter at any time become due the
Contractor under and by virtue of this
Contract. In case such expense is less than
the sum which would have been payable under
this Contract if the same had been 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 id the same has
been completed by said Contractor, then the
Contractor or his Surety shall pay the amount
of such excess to the Owner.
b. The Owner under sealed bids, after 14 days
notice published two or more times in a
newspaper having a general circulation in the
county of location of 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 bond
therefor. However, should the cost to
complete any such new contract prove to be
21
less than what would have been the cost to
complete under this Contract,the Contract or
his Surety shall be created therewith.
8.04 Final Acceptance. When the work has been
completed the Contractor and his Surety shall be
so notified and a Contract Completion Certificate
as hereinafter provided shall be issued. A
complete itemized statement of the Contract
accounts certified by the Owner as being correct
shall then be prepared and delivered to the
Contractor and his Surety, whereupon the
contractor, his Surety or the Owner, as the case
may be, shall pay the balance due as reflected by
said statement within 15 days after the date of
such Contract Completion Certificate.
8.05 Disposition of Contractor's Equipment. 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 or his
Surety pay the balance shown to be due then to the
Owner, then all machinery, equipment, tools,
materials, or supplies left on the site of the
work shall be turned over to the Contractor or his
Surety. Should the cost to complete the work
exceed the contract price, and the Contractor or
his surety fail to pay the amount due to the Owner
within the time designated hereinabove, and there
remains any machinery, equipment, tools,
materials, or supplies on the site of the work,
notice thereof together with an itemized list of
such equipment and materials shall be mailed to
the contractor 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 by the Owner 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 15 days from the date of said
notice the Owner may sell such machinery,
equipment, tools, materials, or supplies and apply
the sum derived from such sale to the credit of
the Contractor and his Surety. Such sale may be
made at either public or private sale, 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
22
and belong to person other than the Contractor or
his Surety to their proper owners.

vertical sides shall be sheeted and braced to the extent necessary to maintain the sides of the required vertical
excavation throughout the construction period. Adequacy of the sheeting and bracing shall be the responsibility of
the Contractor but shall be subject to review by the Engineer. After the pipe has been laid and the backfill placed and
compacted to 12 inches above the top of the pipe, any sheeting, shoring and bracing required may be removed with
special care to insure that the pipe is not disturbed. As each piece of sheeting is removed. the space left by its
removal must be thoroughly filled and compacted with suitable material and provision made to prevent the sides of
the trench from caving until the backfill has been completed. Any sheeting left in place will not be paid for and shall
be considered subsidiary to the pipe item bid.

holes with the crown of the inlet pipe installed at the same elevation as the crown of the existing pipe. Service
stubs Installed on the existing system shall be installed by use of tapping saddles unless otherwise approved
by the Engineer. Extreme care shall be exercised to prevent material from depositing in the existing pipe as the
taps are being made.
When connections to existing mains are made, a temporary plug approved by the Engineer must be installed
downstream in the manhole to prevent water and debris from entering the existing system before final accep-
tance. These plugs shall be removed after the castings are adjusted to finish grade or when final acceptance is
given.
(24) Water System Connections
The Contractor shall, at his expense, make all necessary connections of new piping or accessories to the existing
water system. To minimize any inconvenience from outages, the Contractor shall schedule all such connections in
advance and such schedule must be approved by the Superintendent of Water Division before beginning any work.
(a) Shutoffs
The City will make all shutoffs on existing water mains where more than one valve is involved. The Contractor
wit be required to notify the Engineer's field representative on the job at least 24 hours prior to the desired time
for any shutoff. Where only one valve will be operated, the Contractor may operate the valve under the imme-
diate supervision of the Engineer's field representative.
(b) Wet Connections to Existing Water System
The Contractor shall make all wet connections called for by the Contract or required to complete the work. A
wet connection shall include draining and cutting into existing piping and connecting a new pipeline or other
extension into the existing pressure piping, forming an addition to the water transmission and distribution
network.
(c) Pressure Taps to Existing Water System
The Contractor shall make all pressure taps called for by the Contract Documents or required to complete the

The full cost of such drilling and any other work required of City crews in order to complete the drilling, will be
charged to the Contractor and will be deducted from funds due the Contractor.
(d) Service Connections
510 04/17/86 Page 30
Where not otherwise indicated, service connections to mains shall be installed at an angle approximately 45
degrees above the horizontal.
The contract price for wet connections shall be full payment for all necessary shutoffs, excavation, removing
plugs and fittings, pumping water to drain the lines, cutting in new fittings, blocking and anchoring piping, bed-
ding and backfilling, placing the lines and service and all site cleanup.
No water containing detectable amounts of chlorine may be drained, released or discharged until specific plan-
ning and appropriate preparations to handle, dilute and dispose of such chlorinated water are approved in
advance by the City and the disposal operations shall be witnessed by an authorized representative from the
City.
Tapping of PVC or AC pipe for service connections may be made using either a service clamp or saddle or a
tapping sleeve recommended by the manufacturer and approved as satisfactory by the Engineer. Direct tap-
ping will not be permitted.
All service connections shall be installed so that the outlet is at an angle of approximately 45 degrees above
horizontal at the main line.
Precautions should be taken to ensure that the tapping saddle or sleeve is placed on the pipe straight to pre-
vent any binding or deformation of the PVC pipe. The mounting chain or U -bolt strap must be tight.
Tapping shall be performed with a sharp shell type cutter so designed that it will smoothly penetrate heavy
walled PVC DR14 and 200 psi AC and will retain and extract the coupon from the pipe.
(25) Backfilling
(a) General
After the pipe has been bedded, laid, jointed, approved and any bedding envelope placed, backfilling shall be
done immediately in accordance with the details indicated, with approved material, except that when mortar
joints are used for jointing storm sewers, no backfill above the bedding shall be placed until the mortar has
cured for at least 6 hours.
During backfilling operations, no heavy equipment which might damage the pipe will be allowed until a mini-
mum cover of 12 inches above the top of pipe is obtained.
During the backfilling operations, special emphasis is placed upon the need for obtaining uniform backfill ma-
terial and uniform compacted density throughout the length and depth of the structure. Extreme care is to be
taken to insure proper backfill over the pipe. The maximum lift of backfill shall be determined by the equipment
selected and in no case shall it exceed 18 inches, loose measurement.
All backfill in streets and under structures will be tested by the City and must satisfy the specified density
requirements conforming to Section 00344, "Testing Laboratory Services" before final acceptance.
(b) General Corrugated Metal Pipe
After the corrugated metal pipe structure has been completely assembled on the proper line and grade and
headwalls constructed when indicated, selected material free from rocks over 8 inches in size from excavation
or borrow, as approved by the Engineer, shall be placed along both sides of the completed structures equally,
in uniform layers not exceeding 6 inches in depth (loose measurement), sprinkled if required and thoroughly
compacted between adjacent structures and between the structures and the sides of the trench or for a dis-
tance each side of the structures equal to the diameter of the pipe if pipe is Laid above the existing ground.
Backfill material shall be compacted to the same density requirements as indicated for the adjoining sections
of embankment in accordance with the goveming specifications thereof. Above the V. point of the structure,
the fill shall be placed uniformly on each side of the pipe In layers not to exceed 12 inches, loose measure.
Prior to adding each new layer of loose backfill material, until a minimum of 12 inches of cover is obtained over
the crown of the pipe, an inspection will be made of the inside periphery of the corrugated metal structure
to determine if any floating, local or unequal deformation has occurred as a result of improper construction
methods.
(c) Backfill Materials
The Engineer may approve any of the following well graded materials:
1. Select trench material
2. Sand
3. Crushed rock cuttings
4. Rock cuttings
5. Foundation Rock
6. Blasted material with fines and rock
7. Cement stabilized material
8. Borrow
Within the 100 year flood plan sand will not be permitted for bedding or backfilling. The Engineer shall approve
the topsoil for areas to be seeded or sodded.
(d) Backfill in Street Right of Way
Placement of backfill under structures and within 2 feet of structures shall be compacted to the required den-
sity using any method, type and size of equipment which will give the required compaction without damaging
Page 31 04/17/86 510
510 04/17/86 Page 32
the pipe or bedding. The depth of layers, prior to compaction, shall depend upon the type of sprinkling and
compacting equipment used and the test results thereby obtained. Prior to and in conjunction with the com-
paction operation, each layer shall be brought to the moisture content necessary to obtain the required density
and shall be kept leveled to insure uniform compaction over the entire layer. Testing for density will be in accor-
dance with Test Method Tex -114 -E and Test Method Tex - 115 -E.
Each layer of backfill must provide the density as required herein. Swelling soils (soils with plasticity index
of 20 or more) shall be sprinkled as required to provide not less than optimum moisture nor more than 2 per-
cent over optimum moisture content and compacted to the extent necessary to provide not less than 95 per-
cent nor more than 102 percent of the density as determined in accordance with Test Method Tex - 114 -E.
Nonswelling soils (soils with plasticity index less than 20) shall be sprinkled as required and compacted to the
extent necessary to provide not less than 95 percent of the density as determined in accordance with Test
Method Tex - 114 -E.
After each layer of backfill is complete. tests may be made by the Engineer. If the material fails to meet the
density indicated, the course shall be reworked as necessary to obtain the indicated compaction and the com-
paction method shall be altered on subsequent work to obtain indicated density and conform to Section 00344,
"Testing Laboratory Services ".
At any time, the Engineer may order proof rolling to test the uniformity of compaction of the backfill layers. All
irregularities, depressions, weak or soft spots which develop shall be corrected immediately by the Contractor.
Should the backfill, due to any reason or cause, lose the required stability, density or finish before the pave-
ment structure is placed, it shall be recompacted and refinished at the sole expense of the Contractor. Exces-
sive loss of moisture in the subgrade shall be prevented by sprinkling, sealing or covering with a subsequent
backfill layer or granular material. Excessive loss of moisture shall be construed to exist when the subgrade
soil moisture content is more than 4 percent below the optimum of compaction ratio density. Backfill shall be
placed from the top of the bedding material to the existing grade, base course, subgrade or as indicated. The
remainder of the street backfill shall be Flexible Base, Concrete or Hot Mix Asphalt Concrete as indicated or to
replace in kind the surface removed to construct the pipe.
(e) Backfill in County Street or State Highway Right of Way
All work within the right of way must meet the requirements of (d) above, as a minimum and shall meet the
requirements of the permit issued by the County when their requirement are more stringent. Prior to the start
of construction, the Contractor will be responsible for contacting the appropriate SOHPT office or County
Commissioner's Precinct Office and for coordinating his activities with the operating procedures in effect for
utility cut permits and pavement repair under their jurisdiction. Approval for all completed work in the State or
County right of way must be obtained from the appropriate Official prior to final payment by the Owner.
(f) Backfill in Railroad Right of Way
All work within the railroad right of way must meet the requirements of (d) above, as a minimum and shall meet
the requirements of the permit issued by the Railroad Owner when their requirements are more stringent.
Approval for all completed work in the railroad right of way must be obtained from the Railroad prior to final
acceptance.
(g) Backfill in Easements
Where not otherwise indicated, all backfill in easements across dedicated parkways, planting spaces, under or
adjacent to utilities, structures, etc., shall satisfy all the requirements for backfill in streets or under structures.
Where there are no requirements for density, the Contractor may select whatever methods and procedures
may be necessary to restore the entire work area to a safe, useful and geologically stable condition satisfac-
tory to the Engineer and generally equal or superior to the conditions prior to construction.
In and near the flood plain of all streams and watercourses and on all slopes subject to erosion by runoff, all
backfill shall be compacted to at least 95 percent of maximum dry density as for street right of way, unless
otherwise directed by the Engineer.
All soil areas disturbed by the construction shall be covered with top soil and seeded conforming to Item No.
604, "Seeding for Erosion Control ". All turf, drainways and drainage structures shall be constructed or re-
placed to their original condition or better. No debris shall remain in the drainways or drainage structures.
(26) Quality Testing for Installed Pipe
(a) Wastewater Pipe Acceptance Testing
Atter the construction is complete, the Engineer shall determine whether the pipeline is to be tested for infiltra-
tion and exfiltration by the low pressure air test method.
Wastewater pipe installed in the City of Austin and its ETJ areas shall be tested for exfiltration and infiltration
as described below In "Exfiltration Test" and "Infiltration Test" or by acceptable low pressure air test, as de-
scribed below. At the conclusion of either test series, the work shall be further tested for pipeline settlement as
described below. The Contractor shall be solely responsible for making proper structural repairs to those ele-
ments which do not pass these test requirements.
(b) Exfiltration Test
The pipeline shall be completely filled with water for its complete length or by sections as determined by the
Engineer. If tested for its complete length, the maximum head at any point shall not exceed 25 feet unless
otherwise indicated. If tested in sections, the manholes in the test section shall be completely filled with water.
After the pipeline has been filled and allowed to stand for 24 hours, the amount of exfiltration shall be calcu-
lated. Any amount in excess of 200 gallons per inch of inside pipe diameter per mile per day shall be cause for
rejection.
(c) Infiltration Test
When the pipe placed in easements is completed, the upper portion of the ditch backfill shall be removed to a
depth of not less than 18 inches below the finished surface and width equal to the original trench width. The
trench shall then be flooded with water until it is completely saturated and water stands in the ditch a minimum
0112 inches deep. In cases of steep terrain, earthen dikes shall be used to assure that water will stand over
the trench. After it is apparent that the trench is completely saturated, the main shall then be inspected with
closed- circuit television for infiltration. Any section of the main or any service stub that indicates excessive
infiltration shall be cause for rejection.
This procedure shall not be used for pipes installed in areas where the P.I. of the surrounding material is 20 or
higher or where the backfill material has a P.I. of 20 or more.
(d) Pipeline Settlement Test
During the infiltration test or after the exfiltration test, the pipe will be TV inspected for possible settlement.
When air testing has been used, water shall be flowed into the pipe to permit meaningful observations. Any
pipe settlement which causes excessive ponding of water in the pipe shall be cause for rejection.
(e) Low Pressure Air Test of Gravity Flow Wastewater Lines
(1) General
Wastewater lines in sizes for which the City has testing equipment may, at the discretion of the Engineer,
be air tested between manholes. Backfmlling to grade shall be completed before the test and all laterals
and stubs shall be capped or plugged by the Contractor so as not to allow air losses which could cause
an erroneous test result. Manholes are to be plugged so they are isolated from the pipe and cannot be
included in the test.
All plugs used to close the sewer for the air test must be capable of resisting the intemal pressures and
must be securely braced. Place all air testing equipment above ground and allow no one to enter a
manhole or trench where a plugged sewer is under pressure. Release all pressure before the plugs are
removed. The testing equipment used must include a pressure relief device designed to relieve pressure
in the sewer under test at 10 psi or less and must allow continuous monitoring of the test pressures in
order to avoid excessive pressure. Use care to avoid the flooding of the air inlet by infiltrated ground
water. (Inject the air at the upper plug If possible.) Use only qualified personnel to conduct the test.
(2) Ground Water
Since the presence of ground water will affect the test results, test holes shall be dug to the pipe zone at
intervals of not more than 100 feet and the average height of ground water above the pipe (if any) shall
be determined before starting the test.
(3) Test Procedure
The Engineer may, at any time, require a calibration check of the instrumentation used. Use a pressure
gauge having minimum divisions of 0.10 psi and an accuracy of 0.0625 psi. (One ounce per square
inch.) All air used shall pass through a single control panel. Clean the sewer to be tested and remove all
debris where indicated. Wet the sewer prior to testing. The average back pressure of any groundwater
shall be determined (0.433 psi) for each foot of average water depth (if any) above the sewer.
Add air slowly to the section of sewer being tested until the internal air pressure is raised to 4.0 psig
greater than the average back pressure of any ground water that may submerge the pipe.

After the intemal test pressure is reached, allow at least 2 minutes for the air temperature to stabilize,
adding only the amount of air required to maintain pressure. After the temperature stabilization period,
disconnect the air supply.
Determine and record the time in seconds that is required for the Internal air pressure to drop from 3.5
psig to 2.5 psig greater than the average back pressure of any ground water that may submerge the
pipe.
Compare the time recorded with the time required as follows:
Pipe Size (Inches) 6 8 10 12 15 18 21 24
Time (Minutes) 3 4 5 6 7.5 9 10.5 12
Any drop in pressure, from 3.5 psig to 2.5 psig, in a time less .n that required by the above table shall
be cause for rejection. When the line tested includes more tneml one size pipe, the minimum time shall
be that given for the largest size pipe included.
When lines are air tested, manholes are to d separately by exfltration or infiltration.
(27) Pressure Pipe Hydrostatic Testing
After the pipe has been Installed and backfilled and all s .e laterals, fire hydrants and other appurtenances in-
stalled and connected, a leakage test, followed by a press... test, will be conducted by the City. The City will fumish
the pump and gauges for the tests. The Contractor will be present and shall fumish all necessary assistance for
conducting the tests. The specified test pressures will be based on the elevation of the lowest point of the line or
section under test. Before applying the specified test pressure, all air shall be expelled from the pipe. If permanent air
vents are not located at all high points, the Contractor shall install corporation cocks at such points.
(a) Pressure Test
The entire project or each valved section shall be tested, at a pressure of 200 psi for a sufficient period (ap-
proximately 10 minutes) to discover all leaking or defective materials. Repairs shall be made by the Contractor
to correct any leaking or defective materials.
(b) Pressure Pipe Leakage Test
A leakage test will follow the pressure test and be conducted on the entire project or each valved section. The
leakage test shall be at 150 psi for at least 1 hour.
(1) Allowable Leakage
Leakage shall be defined as the quantity of water that must be supplied into any test section of pipe to
maintain the specified leakage test pressure (see above, "Pressure Pipe Leakage Test ") after the air in
the pipeline has been expelled and the pipe has been filled with water. The allowable leakage shall com-
ply with AWWA C -600 which defines the allowable leakage as:
L _ SD P i
133,200 '
where L = Leakage in gallons per hour
S = Length of pipe in feet
D = Diameter (inside) of pipe in inches
P = Pressure in pounds per square inch
If such testing discloses leakage In excess of this specified allowable, the Contractor, at his expense,
shall locate and correct all defects in the pipeline until the leakage is within the indicated allowance.
(28) Service Charges for Testing
No charge will be made to the Contractor for the City's test equipment, inspection, etc., when the test results show
that leakage is within the indicated allowable limits.
For each test, either for leakage or for pressure, which fails to meet the indicated requirements, the City's flat charge
of $50.00 for such tests will be charged to the Contractor and will be deducted from any funds due the Contractor.

Sterilization of Potable Water Lines
The Contractor shall protect all piping materials from contamination during storage, handling and installation. Prior to
disinfection, the pipeline Interior shall be clean, dry and unobstructed. All dirt, debris, gasket lubricant, etc., shall be
washed from the line by swabbing with hypochlorite solution and/or flushing with clean water.
The City, at its expense, will supply the test gauges and the concentrated disinfecting material and City personnel
will supervise and direct the overall sterilization procedure. The Contractor, at his expense, shall provide all other
equipment, supplies and the necessary labor to perform the sterilization under general supervision of the City.
(a) Procedure and Dosage
All valves shall be arranged to prevent the strong disinfecting dosage from flowing back into the existing water
supply piping. The new pipeline shall then be completely filled with disinfecting solution by feeding the concen-
trated chlorine and approved water from the existing system uniformly into the new piping in such proportions
that every part of the line has minimum concentration of 50 parts per million (50 ppm or 50 mg/liter) available
chlorine.
Unless otherwise indicated, all quantities called for herein refer to measurements by the testing procedures in
the current edition of "Standard Methods ". The chlorine concentration of each step in the sterilization proce-
dure shall be verified by chlorine residual determinations. This disinfecting solution shall be retained in the
piping for at least 24 hours and all valves, hydrants, etc., shall be operated to disinfect at their parts. After this
retention period, the water shall contain no less than 25 parts per million chlorine throughout the treated sec-
tion of the pipeline.
This heavily chlorinated water shall then be carefully flushed from the line until the chlorine concentration is no
higher than the residual generally prevailing in the existing distribution system or approximately one part per
million. Proper planning and appropriate preparations to handle, dilute and dispose of this strong chlorine solu-
tion without causing injury or damage to the public, the water system or the environment must be approved by
the City before flushing of the line may begin and the flushing shall be witnessed by an authorized represen-
tative of the City.
(b) Bacteriological Testing
After final flushing of the strong disinfecting solution, water samples from the line shall be tested for bac-
teriological quality by the City and must be found free of coliform organisms before the pipeline may be placed
in service. One test sample shall be drawn from the end of the main and additional samples collected at inter-
vals of not more than 1000 feet along the pipeline.
The Contractor, at his expense, shall install sufficient sampling taps at proper locations along the pipeline.
Each sampling tap shall consist of a standard corporation cock installed in the line and extended with a copper
tubing gooseneck assembly. After samples have been collected, the gooseneck assembly may be removed
and retained for future use.
Samples for bacteriological analysis shall be collected only from suitable sampling taps in sterile bottles
treated with sodium thiosulfate. Samples shall not be drawn from hoses, fire hydrants, etc. The City, at its
expense, will fumish the sterile sample bottles and may, at its discretion, collect the test samples with City
personnel.
If the initial disinfection fails to produce acceptable sample tests, the disinfection procedure shall be repeated
(without extra compensation) until satisfactory test results have been obtained before the piping may be
placed in service.
(30) Cleanup and Restoration
It shall be the Contractor's responsibility to keep the construction site neat, clean and orderly at all times.
Cleanup shall be vigorous and continuous to minimize traffic hazards or obstructions along the streets and to drive-
ways. Trenching, backfill and cleanup shall be coordinated as directed by the City. The Engineer shall regulate the
amount of open ditch and may halt additional trenching if cleanup is not adequate to allow for orderly traffic flow and
access.
Materials at the site shall be stored in a neat and orderly manner so as not to obstruct pedestrian or vehicular traffic.
All damaged material shall be removed from the construction site immediately and disposed of in a proper manner.
All surplus excavated materials become the property of the Contractor for disposal at his expense. After trenching,
the Contractor shall immediately remove all excavated materials unsuitable for or in excess of, backfill requirements.
Immediately following the pipe laying work as it progresses, the Contractor shall backfill, grade and compact all
excavations as provided elsewhere and shall immediately clean up and remove all unused soil, waste and debris
and restore all surfaces and improvements to a condition equal or superior to that before construction began and to
