TASK 1 - PROJECT MANAGEMENT
This task is divided into the following subtasks:
1.1 Project Schedule, Coordination, and Control
1.2 Establish Standards
1.3 Manage Budget
1.4 Coordination and Communication with OWNER
1.1 Project Schedule, Coordination, and Control
Completion of this project on time and within budget requires a well-organized and
efficient administrative effort. This step includes work planning, scheduling of
personnel, and conducting an initial meeting with the OWNER to review the types and
location of available information. At the initial meeting with the OWNER, the work
scope and schedule will be discussed, and key issues will be identified. Based on these
discussions, the CONSULTANT will develop a project schedule to reflect the work scope
identified.
Project administration includes the development and maintenance of a project filing and
document control system; operation of project office space and communication systems;
conducting regular project team meetings for effective communications and coordination;
tracking actual project progress and costs in comparison to the work plan and schedule;
and preparing project status reports to keep the project team and OWNER officials
apprised of the project progress.
1.2 Establish Standards
CONSULTANT will review OWNER's existing design and construction standards and
establish proposed standards of design and construction for sewer rehabilitation methods.
This includes establishing OWNER's requirements concerning the extent of analysis and
investigation for which services are being offered as part of the bond issue.
1.3 Manage Budget
Project budgets will be established and managed effectively to account for components of
each Phase of this project. This includes tracking actual project progress and costs in
comparison to the work plan and schedule developed at the outset of the project. Each
major subcontractor will submit monthly status reports tracking actual work progress
versus both schedule progress and actual work progress and actual costs of work

;l
completed. The CONSULTANT will utilize these to make any necessary adjustments in
project resource allocations.
1.4 Coordination and Communication with OWNER
The overall objective of the project administrative effort is to ensure effective utilization
of project resources and provide the high level of communication and coordination
among members of the CONSULTANT and between Team and OWNER staff that is
essential for successful project completion.
We anticipate conducting approximately one formal scheduled meeting every 6 to 8
weeks for this project. Routine informal meetings with the OWNER's Project Manager
will be conducted as necessary to ensure effective ,coordination of the work, but such
routine project communications are considered to be integral parts of the various work
tasks.
TASK 2 - MOBILIZATION
This task includes work planning, scheduling of personnel, and conducting an initial
meeting with the OWNER to identify the types and location of proposed fieldwork. This
meeting is important and will allow the CONSULTANT to receive feedback from the
OWNER on desired focus and approach for this project.
TASK 3 - MANHOLE INSPECTION
Perform intermediate level inspection on up to 250 manholes in the Butler Creek, Rocky
Creek, and Spirit Creek Basins in the areas identified below:
Draina2e Basin Manhole Inspection Areas
Spirit Creek Basin ~- . meter location 21 to meter location 24

There is no descent into the manhole for data-capture during intermediate-level
inspection. By mutual agreement between OWNER and CONSULTANT, the number of
manholes receiving intermediate level inspection in each drainage basin may be adjusted
provided that the total amount budgeted for manhole inspection is not exceeded.
Amendment to Appendix I to Exhibit A
Detailed Scope of Services Phase 11
Page 3 of 12
Each of the following items will be checked:
· The casting/cone condition and manhole cover will be evaluated for such items as
vented covers that are in low ponding areas since defects in casting cone connections
and covers are possible inflow sources. A surface orientation photograph will be
taken.
· Manhole walls will be checked for integrity and signs of root intrusion, heavy
infiltration, deterioration of mortar joints, loose or missing bricks, signs of surcharge
level, etc. A photograph of the plan view of the manhole will be taken.
· The bench will be checked for types and depths of debris, flow conditions through the
manhole, and any signs of settlement that may impede achieving design flows.
· Sewer lines entering and leaving each manhole will be compared to existing maps and
corrections will be noted. All sewer lines entering and leaving the manhole will be
manually inspected or remotely viewed to determine the manhole line condition and
establish if any manhole settlement has separated or sheared pipelines.
· Inspection of each incoming and outgoing pipeline to determine line conditions.
Manual measurement/remote estimate to establish size of sewer will be taken and
pipeline material will also be noted. Photographs of pipelines upstream and
downstream of the manhole will be taken.
· Any silt deposition that reduces flow capacity will be recorded and silt depth will be
measured/estimated. Observed defects (root intrusion, cracked pipe, obstructions,
etc,) will be documented and photographed,
At a minimum, the following data will be recorded for each manhole inspection:
· Identity of each manhole in accordance with agreed manhole identification system
· Covered (buried or paved over) or unlocated manholes
· Depth of manhole
· Manhole size and opening
· Number and size oflioles, if any, in vented manhole cover
· Construction materials
· Direction of flow
· Surcharge level
· Photograph
These data will be entered onto physical inspection forms in the field, and then entered
into the GIS database in the office. Both hard copy and digital formats will be submitted
to the OWNER following completion of the inspections,

TASK 4 - SEWER CONDITION INSPECTION
Sewers within the limits of the evaluation will be identified and prioritized based on flow
metering data, manhole inspection data, and' hydraulic analysis results for flow isolation,
smoke testing and for inspection by closed-circuit television.
4.1 Flow Isolation
Flow isolation consists of taking manual flow measurements at successive manholes
along a sewer to identify specific reaches with the highest III flows. Instantaneous flow
measurements will be obtained using hand weirs during early morning hours (midnight to
6:00 a.m.) when sanitary flow is minimal. Where weiring is not practical, the flow will
be measured by dipstick and velocity measurements. ' The results of flow isolation will be
documented on preprinted forms.
In the subbasins with the highest GWI contribution (gpd/idm), nighttime flow isolation
will be conducted to further isolate specific reaches of sewers with the highest III
contributions. Flow isolation is recommended along the tributaries to the sewer reaches
listed below, up to 40 flow isolation setups.
Results of flow isolation are not meant to be used to quantify III, but are useful in
prioritizing TV inspection work. Data collected as part of this task will be analyzed and
used in conjunction with temporary flow metering data to identify and prioritize TV
inspection in those reaches identified as having the highest contributions of inflow and
infiltration. Following flow isolation, TV inspection will be recommended in those pipe
reaches verified as having the highest GWI contributions. Microsystems including
approximately 3,000 feet of sewer mains that drain to a single outlet point will be
delineated for flow isolation,

4.2 Smoke Testing
Sewer reaches were identified for smoke testing based on analysis of flow monitoring
data. Smoke testing is intended to detect 'specific inflow points such as storm sewer
cross-connections; point source inflow leaks in drainage paths or ponding areas; roof
leaders; cellar, yard and area drains; abandoned building sewers; and faulty service
connections. Smoke testing will be performed during dry periods (non-rainfall events and
low groundwater conditions) to maximize the effectiveness of the smoke-testing program.
Public notification is very important in smoke testing. If a house is not properly plumbed
or a trap is dry, smoke may enter the house. During the smoke-testing phase,
CONSUL T ANT will communicate daily with the local fire department and citizens being
affected by the testing. The OWNER and the appropriate public safety agencies (fire and
police departments) will be notified of the location of field crews each day prior to
commencing the tests. Notices will be distributed to nearby residences and businesses
approximately 24 to 48 hours in advance of smoke testing in any given area. Notices for
testing on Mondays will be distributed the preceding Friday, Key contacts at affected
municipalities other than OWNER's will also be notified before initiation of smoke
testing activities in their jurisdiction.
The smoke test crew will walk the surrounding area and visually detect the presence of
smoke escaping from the sewer through leaks, breaks, and other III sources. Smoke test
results will be recorded on preprinted, computerized data forms. A smoke sketch will be
prepared that includes the smoke testing personnel, location (address or house number),
data, and a schematic layout of the manhole and sewer line under testing. The smoke data
identify the type of defect, the area and type of surface drained by the leak, and tie the
leak to at least two measured distances from permanent objects. Estimated leak rates are
assigned, and the size and density of the smoke encountered is noted with reference to the
suspected nature of the problem. The data from the form describing the smoke test leak
will be entered into th~xisting proprietary asset computer database and, subsequently, to
the GIS and MMP databases.
Color photographs will be taken for each defect, showing the amount of smoke from the
leak. The photograph will be close enough to show the exact source of smoke. The
photographs will be numbered in a logical, consecutive manner to ensure the leak can be
identified at a later date.
Smoke testing is recommended in those subbasins with the highest unit RDIII peak flows
and those with relatively consistent flow hydro graphs and significantly high peak
responses to rainfall events.

Smoke testing data will be analyzed to quantifY observed defects and to identifY potential
dyed water flooding locations. Summary reports will be produced to itemize the nwnber
and type of smoke leaks for each subbasin. This information will allow CONSULTANT
to characterize the I/I sources in each subbasin and, compare the relative severity of I/I
problems, This type of summary will provide the OWNER with a big picture view of the
smoke testing results. The detailed data will also be used to identifY specific sources
requiring further verification.
For potential storm drain cross connections identified by smoke testing, dyed water
flooding with concurrent TV inspection will be recommended to identifY the location of
the cross connection and verifY whether the connections are direct or indirect. For
mainline defects identified by smoke testing, TV inspection will be recommended to
identifY the specific defect and location of the problem within the pipe.
4.3 TV Inspection
Flow isolation data collected as part of subtask 4.1 will be analyzed and used in
conjunction with temporary flow metering data to identifY and prioritize TV inspection in
those reaches identified as having the highest contributions of inflow and infiltration.
Following flow isolation, TV inspection will be recommended in those pipe reaches
verified as having the highest GWI contributions.
F or potential storm drain cross connections identified by smoke testing as part of subtask
4.2, dyed water flooding with concurrent TV inspection will be recommended to identify
the location of the cross connection and verifY whether the connections are direct or
indirect. Dyed water flooding with concurrent TV inspection is not included as part of
this scope of services. For mainline defects identified by smoke testing, TV inspection
will be recommended to identifY the specific defect and location of the problem within
the pipe.
4.3.a TV Inspection with Light Cleaning. Normal, or light, cleaning, is defined as
cleaning of a sewer line that has an average depth of foreign material and debris equal to
no more than 20 percent of the diameter of the pipe over the manhole-to-manhole pipe
length. Rocks are smaller than three inches in diameter. Normal, or light, cleaning, is
included as part of this scope of services. Heavy cleaning is defined as cleaning of a
sewer line that has an average depth of foreign material and debris equal to more than 20
Amendment to Appendix 1 to Exhibit A
Detailed Scope of Services Phase II
Page 7 of 12
percent of the diameter of the pipe over the manhole-to-manhole pipe length. Rocks may
be larger than three inches in diameter. Heavy cleaning is not included as part of this
scope of services.
After light cleaning, pipe segments will be visually inspected by means of closed-circuit
television. TV inspection will be performed using a color TV monitor and camera on line
segments suspected as entry points for III based on analysis of results of previous field
testing techniques. Where conventional TV inspection equipment is inappropriate and
cannot be used, sonar, or combined sonar/TV inspection (TISCIT) will be used. The
primary purpose of this equipment is to ensure that sewers will be surveyed regardless of
the level of flow and quantity of silt encountered.
TV inspection and TISCIT data will be used to determine the location and extent of any
defects within a pipe that may permit infiltration and inflow to the sewer. The following
table identifies the approximate linear footages of sewer that may require inspection:

Spirit Creek Basin 14,000
Butler Creek Basin 22,000
Rocky Creek Basin 21,500
TOTAL 57,500
During TV inspection, the specific location of III sources and pipe defects, the overall
condition of the pipe, and the estimated flow rate in the selected segments will be
determined. Descriptive records of all structural defects, service connections, abnormal
conditions and other pertinent observations will be documented, Computerized entry of
TV inspection data will be performed during actual inspection of the sewer. Videotapes
of the TV inspection wilLbe produced and provided to the OWNER.
The results of the inspection will be a record of conditions found in each line segment.
The record will identify each defect and specify its location along the sewer so that it can
be accessed for repair, if warranted.
4.3.b TISCIT or Sonar. No cleaning is required or will be performed in instances
where TISCIT or sonar is used. An additional 10,000 linear feet of TISCIT or sonar may
be required and are included in this scope.
4.4 Easement Clearing
CONSUL T ANT shall secure the services of a subcontractor to clear up to 38,000 linear
feet of easements for equipment access prior to initiation of source detection work
associated with this project. A path up to 12-feet wide, wide enough for vehicle access,
will be cut and ground. No soil erosion, sediment control, or grassing will be required.
Amendment to Appendix 1 to Exhibit A

TASK 5 - FLOW MODELING
CONSUL T ANT will utilize the calibrated models, developed as part of Phase I of this
project, to analyze the Butler Creek and Rocky Creek Basins sewer systems during wet
weather conditions. The model will indicate prioritization of projects according to
capacity rating and III problems.
The developed model will be capable of simulating dynamic conditions as appropriate for
the determination of pipe sizes needed for the design condition. For dynamic conditions,
the model will be calibrated by comparing computer-routed flows to the developed wet
weather unit hydrographs. Adjustments will be made to the upstream input design flows
to ensure that a reasonable match is obtained in both volwne and peak. flow.
Three (3) scenarios will be evaluated using OWNER's established design criteria.
CONSUL T ANT will develop the following design scenarios:
· Existing condition model with existing design wet weather flows showing existing
wet weather problem areas,
· Design condition dry weather model with needed proposed facilities.
· Design condition wet weather model with needed proposed facilities.
CONSUL T ANT will analyze capacity deficiencies with alternative analysis modeling for
the best rehabilitation solutions.
TASK 6 - STUDY, ANALYSIS, AND REPORTING
The purposes of this task are to perform an integrated engineering analysis of flow
monitoring and sewer condition inspection data, develop recommendations for III source
repairs and potential improvements to the collection and transport system, and prepare
reports summarizing the-findings and recommendations developed during the project.
CONSUL T ANT will perform an alternative analysis, making specific recommendations
for preliminary design. Defect information gathered during TV inspection will be used to
identify specific defects that require correction to compare alternative rehabilitation
methods and corresponding costs. The rehabilitation technique to repair a sewer line
shall be selected only after the pipeline has been televised.
6.1 Integrated Analysis of Findings
CONSUL T ANT will integrate the findings of the capacity analyses performed as part of
Task 5 with cost-effectiveness analyses performed as part of subtask 6.5 to develop
recommendations for capital improvements to provide for needed hydraulic capacity in
the trunk sewer system. Such improvements might include construction of relief trunk
sewers, expansions of pwnp stations and wastewater treatment plants, diversion storage
Amendment to Appendix I to Exhibit A
Detailed Scope of Services Phase II
Page 9 of 12
for peak flows, and rehabilitation of the sewer system to reduce peak III flows, thereby
minimizing or eliminating the need for some relief facilities.
Projects required to correct major III sources, severe structural deficiencies, and
operations and maintenance problems will also be developed based on the source
detection work conducted as part of these Phase II services.
6.2 Geotechnical Review
Ultimate rehabilitation solutions are dependent on the nature of the sewer defect
encountered and the surrounding ground conditions.
6.2.a Desktop Review. CONSUL T ANT will conduct a desktop review to locate
relevant existing detailed borehole logs and test results, if available, in the vicinity of the
subject sewers. General soil information will be used to characterize the general
geological and geotechnical conditions in the area of the specific interceptors.
CONSULTANT will utilize local knowledge from constructed pipelines and other
pertinent structures in the area, The objective of this review will be to establish the
following:
· Nature and type of soils adjacent to sewers proposed for rehabilitation.
· Ground water levels including levels adjacent to water courses and more remotely at
the upstream areas of the catchment
. Presence of rock
· Presence of fault lines or similar geological features
Sources for this information may include the following:
· OWNER-provided information
. USGS data
· Local geotechnical contractors
· Local general and pipeline contractors
6.2.b Borehole Survey and Water Level Measurement. CONSULTANT will
perform a limited supplementary borehole survey including piezometer tests at strategic
locations to establish ground water levels and clarify seasonal variation in ground water
levels where previous knowledge is not available.
Eight (8) boreholes will be drilled to substantiate the nature of the soils in areas where
information is unavailable or uncertain. Four (4) piezometers will be placed for up to six
months to establish water levels and seasonal variation,
6.2.c Industrial Effluent Analysis. CONSUL T ANT will perform a review and
sampling, as necessary, of the effluent discharged by some industries in the Butler Creek
Amendment to Appendix 1 to Exhibit A
Detailed Scope of Services Phase II
Page 10 of 12
and Rocky Creek Basins to determine corrosivity. CONSULTANT will also review
industrial discharge permits. Results of this analysis will be used to help determine
rehabilitation recommendations.
6.3 Environmental Review
The interceptors included as part of this scope of services are located in somewhat
environmentally sensitive areas. This task will address concerns regarding rehabilitation
work in these areas.
6.3.a Aquatic Environment. Part of the rehabilitation work will involve clearing
easements and facilitating access to sewers through wetland areas for rehabilitation
equipment. CONSUL T ANT will assist. in delineating wetland issues that may be
encountered as part of the rehabilitation effort and in determining and executing any
necessary applications to the Corp of Engineers for permission to carry out the
rehabilitation effort and establish access and remedial requirements.
6.3.b Construction Impacts. CONSUL T ANT will establish noise levels for carrying
out work near residential areas. CONSUL T ANT will also establish the nature and
frequency of the traffic regime in the vicinity of sewers to be rehabilitated regarding
structural loading and accessibility.
6.4 Probable Construction Costs
The objective of Task 6 is to develop recommendations for improvements to provide for
needed hydraulic capacity in the trunk sewer system and rehabilitation of the sewer
system to reduce peak VI flows, thereby minimizing or eliminating the need for some
relief facilities. CONSULTANT shall prepare an estimate of design, bidding, and
construction cost and duration for recommended projects.
6.5 Alternate Analysis
The objective of the cost-effectiveness analysis will be to determine if relief facility
requirements, as determined by the capacity analysis, could be cost-effectively reduced by
reducing the peak flows in the system, Reduction in peak flows can be accomplished by
rehabilitation of sewers to remove sources of III entry into the system,
The basic cost-effectiveness analysis will involve the comparison of the cost for sewer
system rehabilitation to reduce VI to the cost savings in required relief facilities. An
optimum level of III removal and rehabilitation will be determined. If the savings exceed
the costs in a subbasin, rehabilitation will be recommended,
Amendment to Appendix I to Exhibit A

· Descriptions of the project rehabilitation scope and maps of the project element
locations based on the GIS maps
· Technical specifications for the rehabilitation techniques and quality control measures
that will be utilized by the construction contractors.
Other aspects of contract bid documents, including front-end documents, erosion and
sediment control requirements, permit requirements,' and wetlands mitigation measures,
will be provided by the Program/Construction manager.
6.7 Prepare Final Report
A draft engineering report for this project will be prepared and will summarize the results
of all previous tasks. The report will describe the work performed during the various
tasks, the procedures and methodologies used, the alternatives evaluated in developing
the recommended plan, and a detailed recommended plan with cost estimates showing
anticipated sewer capacity increases to be expected. The draft report will recommend an
III correction plan and present a recommended capacity correction program. Ten (10)
copies of the draft engineering report will be submitted to OWNER for review.
