Don Bunn, City Engineer—
From: Jim Beavers, Project Manager
Date: 13 December 1991
Re: Change order to the construction contract with
C. W. Combs Construction for the 1991 Water line
replacements, "as -needed" (contract 336) for a fire
hydrant at Hotz Hall
1. Existing contract.
The water line replacement project is a 1991 C.I.P. project
funded by sales tax "pay-as-you-go", account 452-952-5-315. The
existing lines have been documented as maintenance problems and
have been scheduled for replacement.
By Resolution no. 170-91, dated September 17, 1991, the Board
approved a contract with C. W. Construction in the amount of
$93,313.00 base contract plus $12,848.00 contingency, for a total
approved project of $106,060.00.
2. Contract changes.
a. previous changes
During the course of construction, certain changes were
incorporated which resulted in quantity variations and a net cost
increase over the base estimated contract. The previous changes
and quantity differences have increased the contract by
$6,115.00.
b. proposed change
The Water and Fire Departments have identified the immediate need
for a fire hydrant in front of Hotz Hall (Cleveland Street).
Engineering recommends that the additional work, estimated to be
$4,340.00, be added to the 1991 water line replacement "as
needed" contract. The proposed additional work is summarized as
follows:

The contractor's proposed unit prices have been reviewed and are
considered fair and reasonable for the proposed fire hydrant and
line work. Coordination with the University of Arkansas has been
started and will be ongoing during the construction.

Re : Waterline Replacements
(Watson Addition Area)
Fire Hydrant @ Hotz Hall
Dear Jim;
12-11-91
I estimate construction cost for the above referenced
project as follows:
1) Fire Hydr. @ Hotz Hall:
6 x 6 tap $ 850.00
70' 6" water @ $12.00 $ 840.00
F.H $ 1,300.00
Test, clean-up & misc. $ 700.00
Open cut Cleveland & repair $ 650.00
$ 4440.00
The quantities were taken off the plans and the unit
prices were taken from the original contract. Actual
total amount will be adjusted up or down depending on
actual quantities installed.
We estimate that it will take an extra 20 calender days
to accomplish this work. This extra time should be added
to the original contract time.

This is a change order to the original contract and
all conditions of the original contract remain in

Please proceed with obtaining approval of this
change order.
Thank you.

such manufacture or construction is carried on. The Owner shall
have the right to reject defective material and workmanship or require its
correction. Unacceptable workmanship shall be satisfactorily corrected.
Rejected material shall be promptly segregated and removed from the site, and

site and charge the cost of the same against any moneys which may be due the
Contractor, without prejudice to any other rights or remedies of the Local
Public Agency.
The Contractor shall furnish promptly all materials reasonably
necessary for any tests which may be required. (See Section - SAMPLES,

Agency at any time before final acceptance of the entire work to make an
examination of work already completed, by uncovering the same, the Contractor
shall on request promptly furnish all necessary facilities, labor, and material.
If such work is found to be defective in any important or essential respect,
due to fault of the Contractor or his Subcontractors, he shall defray all the
expenses of such examination and of satisfactory reconstruction. If, however,
such work is found to meet the requirements of the Contract, the actual cost
of labor and material necessarily involved in the examination and replacement,
plus fifteen (15) percent of such costs to cover superintendence, general

2.5 TRENCH EXCAVATION (WATER LINES)
' The trench shall be excavated to the alignment and grade specified
and only so far in advance of the pipe laying as the Engineer shall permit.
' The trench width may vary and depend upon the depth and the nature
of the excavated material encountered. The trench shall be of ample width to
' permit the pipe to be laid and jointed properly and the backfill to be placed
and compacted properly. The minimum width of unsheeted trench shall be at
least one (1) foot greater than the nominal diameter of the pipe and the
maximum clear width of trench shall be not more than two (2) feet greater than
' the nominal diameter of the pipe.
The bottom of the trench shall be prepared so as to provide a uniform
' and continuous bearing and support for the pipe on solid undisturbed or compacted
ground at every point between bells.
' Any material placed in the bottom of the trench shall be thoroughly
compacted by hand or mechanical tamping devices in lifts not to exceed four
(4) inches. Select backfill material shall be used and shall not contain rock
larger than 3/4 inch in longest dimension. The material shall be at or near
' optimum moisture content and shall not contain organic debris.
When excavation is carried below or beyond the specified or required,
' the Contractor shall backfill the trench to the proper grade as specified in
the preceding paragraph unless permitted by the Engineer to install the pipe-
lines or appurtenances at the undercut grade.
' The use of trench -digging machinery will be permitted except in
places where operations of same will cause damage to .trees, buildings, or

2.9 BACKFILLING
L
I
L
I
L1
I
Backfilling of gravity sewer and water lines shall include the
refilling and consolidating of the fill in the excavation up to the surrounding
ground surface or road grade at crossings. It is essential that the complete
backfill be done in such a manner to minimize voids in the backfill.
Backfilling shall be done with good earth, sand or gravel and shall
be free from large rocks or hard lumpy material. No material of a perishable,
spongy or otherwise unsuitable nature shall be used in backfilling.
After the pipe has been placed, the method of backfilling the pipe
excavations from the springline of the pipe upwards shall be as follows:
Selected materials shall first be taken from the spoil bank moistened to
slightly above optimum moisture content as determined by AASHO T-99 and care-
fully placed on both sides of the pipe simultaneously in layers of not more
than six (6) inches in loose thickness, and these layers shall be firmly
compacted by using vibratory compactors for sands and pneumatic tamps for
clays. The required density shall be equal to or greater than 95% maximum
density as obtained by AASHO T-99. If the previously compacted layer has been
allowed to dry out it shall be rewetted and recompacted as specified above.
This process shall be continued until the backfill is brought up to one foot
above the top of the pipe. This method shall extend full width of trench or a
minimum distance of six (6) feet on each side of the center line of the pipe.
Hand tamping will not be allowed. Backfill for areas that are to receive
riprap slope protection shall be accomplished to 95% maximum density to the
top of the surface which is to receive the riprap.
Consolidation of backfill from one (1) foot above the top of the
pipe to the original ground surface may be accomplished by flooding or jetting,
at the Contractor's option, in lieu of compacting as specified above, provided
it is done in such a manner to secure uniform consolidation and meets the
approval of the Engineer. If the Contractor elects to consolidate the backfill
above the pipe by flooding or jetting, it shall be done in the following
manner. After the trench has been refilled, the earth shall be consolidated
by jetting and flooding until full settlement has been reached. The jetting
shall be accomplished by pumping water through a pipe that is slowly inserted'
vertically into the backfill. The end of the pipe shall be lowered to a point
near the top of the previously compacted backfill. The excavation shall then
be flooded in puddles until no more appreciable absorption of water into the
backfill occurs.
Backfill of manholes shall be in accordance with the following:
(1) Backfill shall be done in the manner similar to that specified
for backfill of pipe except that, in all cases, the use of mechanical tamper
will be continued to the elevation of natural ground.
(2) Backfill will be brought up with reasonable uniformity around
the structure. Backfill shall not be begun until the ends of the periods
specified in SECTION 3 - HANHOLES.
Other methods of backfill may be used if approved by the Engineer
and the Contractor is able to accomplish the specified results without damage
to the pipe.
2-7
Backfill on State right-of-way shall be made of suitable material,
free from large clumps and clods, in layers not to exceed eight (8) inches
(loose measurement) compacted with mechanical tampers to 95% density to the
top of the subgrade and roadway section. The moisture - density relations of
soil shall be determined in the laboratory in accordance with AASHO Designation
T180-61, Method "C" or Method "D". The field determinatioq of soil in -place
shall be in accordance with AASHO Designation T147-54. Th.: aubgrade shall
then be excavated three (3) feet outside the cut trench on each side, to a
pdeth of nine (9) lans and discussed ihreplaced tion as shown on the
n SECTION 9- RESTORATION OF SPECIAL SURFACES.
Backfill on City right-of-way may be performed by jetting, provided
it meets the following requirements:
(1) Requirements of this paragraph.
(2) Jetting of backfilled trench shall be maintained within a
distance of 100 feet of the pipe laying operation provided that jetting water
does not interfere with the pipe laying.
(3) Application of temporary stone surfaces shall be made as specified
in SECTION 9 - RESTORATION OF SPECIAL SURFACES.
Backfill will not be measured for separate payment but shall be
considered subsidiary work pertaining to the construction of the involved
item.
2.10 MEASUREMENT AND PAYMENT
Trench excavation for the sanitary sewer pipe, water lines, excava-
tion for manholes, sheeting, bracing, dewatering operations or other type of

7.12 STERILIZATION
Blowoff and sample points shall be constructed by the Contractor as
shown on the Plans or as directed by the Engineer. Fire hydrants shall be
utilized as blowoff points whenever possible. However, fire hydrants are not
satisfactory for sample points. Openings for sample points shall be 3/4"
copper riser pipe which extends well above the surface.
There are three acceptable methods of disinfecting: continuous feed
method using liquid chlorine or calcium hypochlorite, the slug method using
liquid chlorine or calcium hypochlorite, and the tablet method using calcium
hypochlorite. The slug method applied to large mains and shall be used only
upon the aoproval of the Engineer. Liquid chlorine shall be used only when
the Contractor has suitable equipment available and employees who are familiar
with the physiological, chemical and physical properties and who are properly
trained and equipped to handle any emergency that may arise. If, in the
opinion of the Engineer, the equipment is inadequate or the personnel are not
qualified, this method shall not be used.
When the continuous feed or slug method is used and the source of
chlorine is calcium hypochlorite, a solution of hypochlorite and water shall
be prepared by mixing thoroughly in a suitable container. The mix shall
contain one (1) pound of calcium hypochlorite per gallon of water. A suitable
pump shall be provided for pumping this solution into the pipe lines to be
disinfected. This pump shall be equipped with a flow measuring device.
When liquid chlorine is used the equipment for injection shall
consist of a solution feed chlorinator in combination with a booster pump for
injecting the chlorine -gas water solution into the pipe line. Introduction of
chlorine -gas directly from the supply cylinder shall not be permitted. The
pump shall be equipped with a flow measuring device.
During application of any chlorine solution, care shall be taken to
assure that the solution does not flow back into the distribution system.

to be tested.
7.12.1 Continuous Flow Method
The procedures for disinfecting by the continuous flow method shall
be as follows:
(a) The flow through the pipe line and the solution flow shall be
regulated so that the required concentration of chlorine is attained. The
flow through the main shall be measured by using a pitot gauge or meter.
7-10
(b) The introduction of the solution shall be continuous until the
desired concentration is attained throughout the pipe line system. The con-
centration shall be checked by the Drop Dilution Method.
(c) After the required concentration has been attained all internal
valves shall be operated in order to assure that the solution comes in contact
with all appurtenances.
(d) The solution shall remain in the pipe line system for twenty-four
(24) hours after which the pipe lines shall be thoroughly flushed. The chlorine
concentration shall be checked before flushing. If the concentration is less
than 25 parts per million the disinfecting procedure shall be repeated if
directed by the Engineer.
7.12.2 Slug Method
The procedure for disinfecting by the slug method shall be the same
as the continuous flow method except that the flow rates shall be regulated so
that the specified concentration of chlorine shall be in contact with all
parts of pipe line for at least three (3) hours.
7.12.3 Tablet Method
The procedure for disinfecting by the tablet method shall be as
follows:
(a) Five gram calcium hypochlorite tablets shall be placed in each
section of pipe, in hydrants, hydrant branches, and in other appurtenances in
sufficient quantities to produce the specified chlorine concentration after
the introduction of water. The tablets shall be placed in the top of the pipe
with Permatix No. I or other approved adhesive. If tablets are placed in the
pipe before jointing, the location of the tablets shall be marked on the
outside of the pipe to assure that the pipe is not rotated. The tablets shall
be placed so that they are not damaged during the laying operation.
(b) After the pipe lines and appurtenances have been installed,
they shall be filled very slowly so that the tablets are not dislodged.
(c) The procedures outlined in Paragraphs 3.12.1(c) and 3.12.1(d)
shall apply.
7.12.4 Sa lin
After final flushing, two consecutive samples of water taken at 24
hour intervals shall be collected from the sample points provided by the
Contractor and tested. The Contractor shall provide any assistance required
in collecting the samples.
If any of the samples collected are positive, the disinfecting
procedures shall be repeated as directed by the Engineer until negative samples
are collected. Only the continuous flow or slug method may be used.
The cost of water used for disinfection and flushing shall he the
responsibility of the Contractor. The costs of testing of the samples will be
the responsibility of the Contractor.
7-11
7.13 MEASUREMENT
Water main will be measured by actual slope field measurements - the
length of valves and fittings shall be included as a part of the total pipe
length. Pipe required for making "tapping connections" to existing mains will
be measured in the field measurement for pipe installed.
Concrete thrust blocks and collars will be measured by volume in
cubic yards in place to the dimension determined by the Engineer. Concrete
required due to overexcavation of the pipe trench will not be included in the
measurement of concrete for payment.
Testing will be measured periodically in proportion to the amount of
line acceptably tested. No differentiation will be made as to size of line
tested.
7.14 PAYMENT
Water mains acceptably completed, and measured as provided above,
will be paid for at the contract unit prices per linear foot bid for the
several sizes listed in the Unit Price Schedule, which price in each case
shall be full compensation for furnishing all materials; and for all equipment,
tools, labor, and incidentals necessary to complete the work.
Concrete thrust blocks acceptably completed, and measured as above
will be paid for at the contract unit prices per cubic yard listed in the Unit
Price Schedule, which price in each case shall be full compensation for furnish-
ing all materials, and for all equipment, tools, labor, and incidentals necessary
to complete the work.
Reinforcing steel in thrust blocks will not be measured for separate
payment but will be considered subsidiary to the installation of the concrete.
Payment for testing will be made periodically in proportion to the
amount of line tested as measured above.
