GUTIERREZ, SMOUSE, WILMUT & ASSOC., INC.
Civil / Environmental Engineers
Gutierrez, Smouse, Wilmut & Assoc., Inc. proposes to furnish Engineering
Services to the City of Round Rock, Texas in accordance with the following:
1. ANALYSIS AREA
The study area includes the Lake Creek Interceptor from Manhole
No. 431 downstream to Manhole No. 159, including parallel sections,
connecting laterals that cross the creek, and the new relief line from
Manhole No. 318 to Manhole No. 175 (reference 1986 Meter Report). This
is estimated to be 25,000 linear feet.
2. SCOPE OF WORK
Conduct evaluation of the Lake Creek Interceptor.
The evaluation survey objectives will be achieved through the per-
formance of the following tasks:

PROPOSAL TO: CITY OF ROUND ROCK, TEXAS
PROJECT: SEWER SYSTEM RENOVATION PROGRAM - Phase I
City of Round Rock, Texas
Task 1 - Preparatory Work.
a. Printing of all field forms to be used in the project.
b. Assist City personnel in delivering flyers used to notify the
general public about the work. Details and final procedures to be
established at the pre -job conference.
c. Preparation of equipment and supplies to be assigned and trans-
ported to the project site.
d. Hold a "Pre -Job" conference prior to commencement of any work to
ensure that all work is conducted in the most economic method,
proper liasion with City personnel, priority of tasks, and that all
safety procedures shall be followed.
e. Traffic and pedestrian control shall be the responsibility of GSW
and shall insure public safety and convenience.
Task 2 - Smoke Testing.
The smoke generated by a smoke bomb, which is odorless and harmless, is
blown into the center manhole connecting two sections of line by an air
blower with a minimum capacity of 1500 CFM. Smoke testing is performed
under dry weather conditions to allow the maximum detection of inflow and
rainfall - responsive infiltration sources.
This task, as described above, will be employed to the extent that
surcharging or blockage of the sewer lines will permit on the 25,000
L.F. of sewer lines in the study area. Above - ground reconnaissance of
the study area to determine proximity of storm sewers, creek crossings,
drainage paths and ponding areas to the sanitary sewer system will be
accomplished concurrently with smoke testing and the visual line inspec-
tion. Polaroid pictures of every smoke leak found will be made and
attached to the field forms.
The unit price for this task is established on a "per linear foot" basis,
and the total price for this task will be based on the actual footage of
sewers on which the smoke testing is attempted. This includes lines with
sags or blockages.
Task 3 - Night Flow Isolation.
This test consists of dividing the trunk line into segments and taking
weir readings during minimum flow periods (11 p.m. - 6 a.m.) to
determine if infiltration rates require additional investigation.
PROPOSAL TO: CITY OF ROUND ROCK, TEXAS
PROJECT: SEWER SYSTEM RENOVATION PROGRAM - Phase I
City of Round Rock, Texas
The price for this task is established on an "hourly rate" basis with the
total price determined by hours expended.
Task 4 - Preparatory Cleaning.
This task consists of preparing the sewer lines to be internally
inspected by cleaning the pipe walls to provide for unobstructed
internal inspection. The cleaning will be accomplished by use of a
hydraulic cleaning unit (jet truck). All lines to be internally
inspected will be cleaned prior to such internal inspection. The intent
of the cleaning is to remove the sludge, mud, sand, gravel, and other
sediment and debris in order to obtain a good television picture. Pro-
truding taps, dropped joints and similar obstructions cannot be removed
by conventional cleaning. It is estimated that about 3,000 L.F. (12
percent) will be internally inspected and thus this amount is estimated
for the preparatory cleaning task.
When obstructions are encountered, an attempt will be made to flush and
thread the line from both upstream and downstream manholes.
The price for this task is established on a "hourly rate" basis with the
total price to be determined by hours expended.
Task 5 - Internal Inspection.
This task consists of the T.V. inspection (closed- circuit television) of
sewer lines estimated at 3,000 L.F. Polaroid pictures of defects
encountered during the T.V. inspection will be made and attached to the
T.V. log sheets. Video tapes will be made of all lines televised. All
lines to be televised will be plugged off to eliminate incoming flows
from up stream collection lines if necessary.
The price for this task is established on "hourly rate" basis and the
total price will be determined by hours expended.
Task 6 - Project Management and Supervision.
This task consists of the direction of field crews, scheduling of these
tasks by the project manager, and the general management and supervision
of project personnel during all phases of the project.
This task will be charged on a lump sum basis, with the total price based
on a percentage of completion.
Task 7 - Engineering Evaluation, Data Analysis, and Report.
This task consists of analyzing collected data and presenting the
results in the form of a report (10 copies) including the following:
PROPOSAL TO: CITY OF ROUND ROCK, TEXAS
PROJECT: SEWER SYSTEM RENOVATION PROGRAM - Phase I
City of Round Rock, Texas
a. Description of the type and nature of the problems found in the
system.
b. Computer print out of problem priorities (rehabilitation ranked by
cost effectiveness to repair).
c. Computer listing of all problems found.
d. Recommend rehabilitation work grouped and tabulated in three (3)
major categories, collection lines, manholes and service lines.
The tables will provide information necessary for the rehabili-
tation work to be done either by the City or by a Contractor.
3. INFORMATION AND SERVICES TO BE PROVIDED BY THE ENGINEER
a. Five copies of sewer maps (1" = 200 ft.), showing sewer lines and
manholes.
b. Liaison with City officials to provide effective coordination and
cooperation between the fire, police, engineering and sewer depart-
ments and GSW, as necessary during execution of field work.
c. Access to manholes.
d. Assistance by City personnel, knowledgable of manhole and cleanout
locations, in locating buried or hidden manholes and cleanouts.
e. Expose for entry, manholes that require excavation, cutting of
pavement, and /or have lids fastened or frozen in place.
f. Water for cleaning unit from the City fire hydrants at no charge
during quantification and TV Inspection.
The necessary equipment and assistance as might be required to
remove the specialized equipment (cleaning nozzle and hose, T.V.
Camera and coaxial cable, sewer plugs, etc.) from the sewer should
the equipment become lodged during the course of the work, and to
complete line repair and restoration of the area.

4. COMPENSATION FOR SERVICES AND TERMS OF PAYMENT
The total price of services described under the Scope of Work is
estimated to be THIRTY NINE THOUSAND FOUR HUNDRED AND FOUR DOLLARS
($39,404.00).
Invoices will be rendered monthly based upon the quantities of work
completed times the unit costs and /or hourly rates times hours expended,
with the lump sum task amounts being established by percent completion.

PROJECT: SEWER SYSTEM RENOVATION PROGRAM - Phase I
City of Round Rock, Texas
The price is based on the estimated quantities and hours listed in the
table on the following page. This total price will not be exceeded
without a justifiable increase in scope and approval by the CITY.
5. TIME SCHEDULE
a. The project can be initiated within two weeks. Completion time for
the various phases of field work including tasks 1 through 5 is
estimated to be six weeks.
b. The final report will be completed within six (6) weeks after the
field work is completed.
