Tasks 4 -8
Dear Chris:
January 13, 2004
MA-5654-CC
SL# 25538
As requested, we are providing you with scopes and budgets for the remaining tasks to complete
the Wastewater Collection System Model & Master Plan. The attached Scopes of Services
reflect our understanding of these tasks based on the work we have completed to date and our
meetings and discussions with you. Included with the detailed Scope of Services are fee
estimates based on the hourly rates set forth in our Master Agreement.
We have begun to build the model using the data collected. As you are aware the prioritization
and error correction of the City data with the data collected has taken considerably longer than
expected. Using the information we have gathered and collated we will make model runs to
produce a model representation of the wastewater system. This model will be used to analyze
the collection system, and determine areas of concern in the existing system. These results will
be used to determine the placement of additional monitors and to analyze the system for future
conditions. The final results of the modeling and flow monitoring will be used to create a capital
improvement plan and a master plan of the wastewater collection system.
Please call if you should have any questions or comments, or need additional information.
Very truly yours,
Rothberg, Tamburini & Winsor, Inc.

ANALYSIS OF EXISTING COLLECTION SYSTEM, TASK 4
(RTW Job No. MA-5653-SC)
For
Wastewater Collection System Model & Master Plan
SCOPE OF WORK
As a part of this Scope of Work, we will request that the City of Fort Collins team provide input
regarding the results of the analysis and assist with corrections of the data by field
confirmation/inspection.
Outline of Proposed Tasks:
SUBTASK 1. INITIAL SYSTEM ANALYSIS AND RESULTS
a. Final computer model runs will be completed to correct errors and determine
additional data needed to insure proper model operation.
b. RTW will review the analysis results and determine areas of concern and the
significance of each problem. RTW will also consider the areas of concern to
determine whether or not they resulted from faulty data or if more information
(i.e. monitoring) is required to confirm the areas of concern.
SUBTASK 2. REVIEW OF MODEL RESULTS WITH CITY AND IDENTIFICATION
OF AREAS/ISSUES OF CONCERNS
a. The results and the areas of concern from subtask 1 will be presented to the City
for consideration and review.
b. RTW together with the City will finalize the list of areas/issues of concern.
SUBTASK 3. DEVELOP PLAN (TECHNICAL MEMORANDUM) FOR ADDITIONAL
FLOW MONITORING SITES
a. Using the list established in subtask 2, RTW will prepare a Technical
Memorandum outlining the steps necessary to complete additional monitoring and
gather additional information to confirm the areas of concern.
SUMMARY OF FEES:
Analysis of Ex. Collection System, Task 4
Subtask 1. Initial Sys. Analysis and Results $7,224
Subtask 2. Review of Result w/ City & ID of Areas/Issues of Concern $ 3,680
Subtask 3 Develop Plan for Additional Flow Monitoring Sites $ 2,204
TOTAL $ 13,108

FLOW MONITORING TASK - PHASE 2, TASK 5
(RTW Job No. MA-5654-SC)
For
Wastewater Collection System Model & Master Plan
SCOPE OF WORK
As a part of this Scope of Work, we will request that the City of Fort Collins provide access and
assistance in identifying and locating the manholes for flow monitoring, installing and removing
the flow monitoring devices within said manholes, and collecting the data from the flow
monitors in order to minimize impacts to traffic, especially in certain locations
Outline of Proposed Tasks:
SUBTASK 1 INSTALL FLOW MONITORING STATIONS
The flow monitors will be installed in the areas of concern as determined in Task 4 of this
Project. RTW's subcontractor, Hydro Construction Inc, will install the flow monitors
with the assistance of City personnel and equipment when feasible.
SUBTASK 2. PORTABLE FLOW MONITORING/COLLECTION & REVIEW OF
DATA
This task includes the collection of the data from each of the sites with assistance from
the City when possible. The observations in the field will be done to insure that the
monitors are properly collecting the data. If the data is not being properly collected,
measures will be taken by RTW to reprogram the monitor, have Hydro enter the manhole
to perform needed maintenance of the sensor (i.e. cleaning or repositioning the sensor as
needed), or call upon the vendor to correct any malfunction of the unit. The data
collection for this stage of the project will be for a period of approximately 1 month.
Once the data is collected it will be reviewed in the office and set up in a database for
input into the H2O Map Sewer model.
SUBTASK 3. MODEL RUN AND RE -CALIBRATION BASED ON NEW DATA FROM
PERMANENT AND TEMPORARY FLOW MONITORING STATIONS
Using all the information gathered, collated, and input into the model, a final model run
of the existing system will be completed. This will entail the final model calibration and
establish a completed existing model.
SUMMARY OF FEES:
Flow Monitoring Task -Phase 2, Task 5
Subtask 1. Install Flow Monitoring Stations $4,706
Subtask 2. Portable Flow Monitoring/Collection & Review of Data $ 17,408
Subtask 3 Model Run and Re -Calibration $ 5,068
TOTAL $ 27,181

ANALYSIS OF FUTURE IMPROVEMENTS, TASK 6
(RTW Job No. MA-5655-SC)
For
Wastewater Collection System Model & Master Plan
SCOPE OF WORK
As a part of this Scope of Work, we will request that the City of Fort Collins team provide input
regarding the results of the analysis of the future system and assist in providing planning
information regarding the future loading of the system.
Using all the information gathered, collated, and input into the model, a final model run of the
future system will be completed. The results of this run will be used to help establish the capital
improvement plan. The goal of this phase of the project is to assure that future improvements are
made under the vision of a buildout plan. Upon review of alternative scenarios with the City,
RTW will confer with the City to select buildout alternatives that best meet the interests
(including costs, political factors, etc.) of the City of Fort Collins.
The analysis will estimate future sanitary sewer collection trunk alignments to accomplish the
long-range needs of the City. As appropriate, the I/I and peaking factors obtained during analysis
of the existing system will be modified to account for improved construction materials and
practices and size of basin(s). This will entail the final model runs and establishment of a
completed future model scenario.
