Exhibit A
City of Fort Collins
24” POUDRE PIPELINE REHABILITATION
ASSESSMENT
Scope of Services
INTRODUCTION
Since its beginning, the City of Fort Collins (City) has aggressively pursued a redundant water
rights and raw water conveyance portfolio for their Water Treatment (WTP) facilities. In fact, the
City has five pipelines (i.e. 24” and 27” Poudre Canyon, 36” Bellvue to WTF, 67” Poudre Valley
Pipeline and 54” Horsetooth) capable of supplying raw water to the City WTP facilities.
There are four (4) pipelines that provide connectivity between the Cache La Poudre river and
the City WTP facilities. Those pipelines consist of:
1. a 24” diameter Reinforced Concrete Pipe (RCP), constructed between 1924 and
1926, that runs from Gateway Park past the mouth of the Poudre Canyon that
connects to a 36” pipeline that feeds the WTP.
2. a 27” diameter steel pipe, constructed in the mid 1950’s, that runs from Gateway
Park past the mouth of the Poudre Canyon that connects to a 36” pipeline that feeds
the WTP.
3. A 36” dimeter steel pipeline that connects to the 24” RCP and 27” steel pipelines
past the mouth of the Poudre Canyon that runs to the WTP
4. a 67” diameter steel pipeline (Poudre Valley Pipeline or PVP) that runs from a point
north of the mouth of the Poudre Canyon to the WTP.
Each of these pipelines (a.k.a. conveyance) has its own unique value to the City in terms of
capacity, reliability, accessibility and “other” considerations. Historically, these pipelines have
performed as intended and met the City’s needs. Unfortunately, over the last few years, the
joints on the 24” RCP have started to leak causing minor disturbances within the Poudre
Canyon. Assessments of the pipeline revealed that the interior of the 24” RCP was in good
condition and that the concrete showed little, if any, deterioration and “looked like new”. The
cast iron joints were in good condition but the gaskets appear to be the source of the leaks. As
the frequency and magnitude of leaks will arguably continue to increase over time, the City has
expressed their concerns with the 24” RCP including, but not limited to:

x x Can What the impacts City access would the future pipeline failure to events make have needed on repairs? the Highway 14 corridor, the Cache La
x Poudre What impacts River, and would surrounding a failure of environment? this pipeline have on the ability to supply potable water
to the City?
Given these concerns, the City has commissioned this analysis to understand how they would
deliver their full water rights from Gateway Park to the WTP, in the event of failure of any of the
existing Poudre conveyance elements - most notable being failure of the 24” pipeline.
Accordingly, this Scope of Services represents the engineering services associated with an
analysis of conveyance and its relationship with the City water rights portfolio within the Poudre
Canyon related to:
1. Assessing the City’s ability to deliver their full water rights to the WTP in the event of
failure of any of the existing Poudre conveyance elements
2. Gaining a firmer understanding of the location and condition of the existing 24” RCP
3. Exploring viable options to repair or replace the existing 24” RCP from the Pre-
Sedimentation Basin to the mouth of the Cache La Poudre Canyon and/or repurposing
other conveyance within the Canyon to carry the full water right conveyance in the event
of failure of the 24” RCP.
The following Scope of Services outlines the work necessary to support the City in their
determination of delivery of their full Poudre water rights and the most appropriate approach to
management of the approximately four-mile-long section of existing 24” RCP in the Poudre
Canyon.
This scope accompanies the Fee Estimate (Exhibit B). The Fee Estimate is a spreadsheet
representing an overview of the project with individual work tasks represented in rows and
anticipated professional staff and subconsultant efforts and expenses represented in columns.

Hydro will assist the project team and lead the pipeline location efforts and provide
constructability reviews and conceptual construction cost estimating. Their Scope of Services
includes subcontracting with an appropriate pipeline location service to provide horizontal and
vertical locations (most notable being pipe bends, fittings and specials that could potentially
interfere with pipeline rehabilitation or replacement programs) on the 24” pipeline. Hydro’s
services will be contracted directly with the City. In turn, Hydro will engage Smartpipe through a
sub-contract agreement for work associated with determining the viability of their services.
All project deliverables will be made available to the City in electronic as well as hard copy
format (i.e. reproducible Mylars and paper copies). Electronic files will be prepared and
formatted in current industry standard software including AutoCAD (DWG) and Adobe (PDF)
formats. The primary project deliverable will be a bound report inclusive of major project work
elements and the value of each conveyance element both in terms of conveyance and raw
water rights. The report will be fully supported with planning level analysis (including conceptual
plan sheets as appropriate to convey design concepts) for each alternative and will include
planning level costs and risk assessments for each alternative. The final report will also include
an executive summary suitable for inclusion in a presentation to City Council by City staff.

SCOPE OF SERVICES
Task 1 - Meetings
1.1 Team Design Meetings
Up to seventeen (17) meetings (bi-weekly for the estimated eight-month project duration)
will be held with Utilities, City Water Rights personnel, Hydro, SmartPipe and others as
necessary to review progress of the work, review and exchange data and analyses, and
discuss approaches and feasibility. Stantec will prepare agenda and minutes for each
meeting.
1.2 Site Visits
Site visits will be made as appropriate to support the needs of the project. As directly
related to rehabilitation of the 24” RCP, site visits will focus on possible locations for the
field factory and insertion and retrieval pits in the Canyon associated with lining the pipe
with Smartpipe. In addition, one (1) trip is anticipated to travel to a location somewhere
in the US to observe installation of Smartpipe’s product. In total, we anticipate up to six
(6) individual trips/visits.
Task 2 - Project Scheduling
2.1 Project Scheduling
The City has budgeted funds to complete this Scope of Services before the end of 2017
to prepare for presentation to Council and implementation of the solution set in 2019-
2020. While this schedule may be general at this stage, Stantec will work with the
project Team and lead the efforts to formulate a Master schedule that is reasonable
considering operational requirements and budget constraints. Stantec will assist in
preparing this Master schedule and placing it in a format that can be utilized by the
Team - and other purposes (i.e. outreach, plant operation, etc.) as necessary.
Task 3 – Field Investigations (24” RCP)
Work under this Task supports acquisition of data to more fully define the horizontal and vertical
location of the 24” RCP.
3.1 Leakage Testing
As part of a complete assessment, the integrity of the 24” pipeline will be investigated.
This task focuses on testing the pipeline to gain a greater understanding of the amount
of water loss between the pre-sedimentation Basin and the connection to the 36” pipe in
Bellvue. Stantec will work with the project team to schedule and perform shutdown of
the pipeline and measurement of the water level in the pre-sedimentation basin over a
period of approximately six (6) hours. The volume associated with the elevation drop in
the pre-sedimentation basin during the test will be used as a measure of water loss. This
method mimics the method used in 2004 to determine losses at that time. The findings
will be included in the final Project Report.

3.2 Review of Pipeline Location and Condition
To date, the alignment of the 24” RCP has only been determined by the location of the
various appurtenances on the pipeline and limited areas where a video camera placed in
the pipe during installation of valves and Swagelining was tracked from the surface. In
all other areas the possible alignment, including bends, fittings, and specials, between
the appurtenances have been approximated.
To more fully understand the location and condition of the 24” RCP, Hydro has
developed a program wherein two people; working in tandem and equipped with radios,
locating wire and a measurement tape; can enter the pipeline and provide
measurements to personnel outside the pipeline to more accurately determine the
horizontal and vertical location of the pipeline. Hydro will also provide a video of the
interior of the pipeline from the Pre-Sedimentation Basin to the mouth of the Poudre
Canyon in those areas not previously inspected. Both the City and Stantec will review
the information provided and locations of appurtenances will be confirmed, unknown
obstructions and conditions documented and the location of bends/deflections/fittings
and valves will be updated in the Poudre Pipeline Manual Drawings-of-Record as more
fully defined below.
Stantec, in coordination with the project team, will coordinate pipeline access locations
and design replacement pipeline sections at said access locations.
3.3 Survey
As part of our analysis, Stantec will obtain critical elevations at key locations and
structures including pipeline access locations, diversion structures, channel and tunnel
and siphon entrances and exits.
Task 4 – Update 24” RCP Plan and Profile Mapping
Work under this Task utilizes the data provided in Task 2 to update the existing Poudre Pipeline
Manual Plan and Profile (P&P) sheets.
4.1 P&P Sheet Updates
Utilizing the data acquired in Task 2, Stantec will update the existing Poudre Pipeline Manual
Plan and Profile sheets and deliver this information to the Project Team for use in determining
the encumbrances associated with replacement or installation of Smartpipe.
Task 5 – 24” RCP Replacement Alternative
Using the updated P&P sheets from Task 3, Stantec will work with the Project Team to
complete a planning level cost estimate to replace the 24” RCP in its entirety.
5.1 Pipeline Replacement
Utilizing the updated P&P sheets for the 24” RCP, Stantec will work with Hydro to
complete a planning level cost estimate to replace both the existing 24” RCP in its
entirety and a single pipeline to replace the capacity of the combined capacity of both
the 24” and 27” pipelines along the project route. It is assumed the cost will be based

on either ductile iron or steel pipe. A geotechnical investigation has not been included in
this task as it is felt Hydro has performed enough excavations along the pipeline route to
understand the soils (e.g. sand, silt, gravel, cobles, boulders) to prepare an adequate
estimate of the level of effort and costs.
Task 6 – Pipeline Rehabilitation/Repair Alternative
Work under this Task focuses specifically on Smartpipe lining of the existing 24” RCP.
6.1 Data Transfer to Smartpipe
Information collected since the year 2004 and included in the Poudre Pipeline
Rehabilitation Project – Final Report and Recommendations (Report), in addition to data
gathered herein including updated P&P sheets, will be provided to Smartpipe for their
use in determining the applicability of the Smartpipe technology. Stantec will supply
existing mapping for their use and copies of video inspections and location information
obtained during this project.
Stantec will coordinate with Smartpipe to determine what additional information would
assist Smartpipe in the proposed application and transfer this information to them. In
addition, it is anticipated Smartpipe will have questions regarding this information and
Stantec will coordinate with them to answer or direct these questions to the proper
person(s).
6.2 Mapping/Exhibits for Analysis and Scheduling
Mapping and/or exhibits contained in the Report will require further definition. While not
anticipated to be extensive, some of the information to be transferred to Smartpipe or
used in design meetings may need to be refined to only cover the limits of the project.
This task will prepare the information required to support the basis for analysis,
scheduling, placement of the field factory, launch and receiving pits, and locations for
valve removal.
6.3 Hydraulic Assessment
The 24” RCP has historically been rated at a carrying capacity of 10.20 MGD.
Reduction of the inside diameter (ID) of the pipe associated with SmartPipe liner will
reduce the ability of the pipe to transport this rate. Stantec will work with Smartpipe’s
Engineer(s) to determine the reduced pipe ID and use this information in conjunction
with an appropriate hydraulic roughness factor for HDPE pipe to evaluate any reduction
in carrying capacity and accompany changes in the hydraulic profile of the pipeline along
its route.
6.4 Field Factory Locations
Information on possible insertion and receiving pit locations must be coordinated with the
entire Project Team – including Smartpipe. As supported by surveys included herein,
the Project Team will collectively use this additional information to determine possible
locations for the setup of Smartpipe’s field factory and insertion and retrieval of the pipe.
The final locations and effort for performance of the work tasks required for installation of
the pipe liner material will be determined. This may include determining the parties (e.g.

federal, state and local) that must be contacted to gain permission for access to these
areas.
6.5 Smartpipe Cost Estimating
Stantec will support Hydro as-needed in obtaining estimates from Smartpipe and
preparing a final project budget estimate.
Task 7 – Pipeline Repurposing Alternatives
Work under this Task focuses specifically on completion of planning level assessments
associated with repurposing and/or modifying existing conveyance within the Canyon as
potential alternatives to replacement of the 24” RCP. The four (4) alternatives currently
envisioned by the Project Team are described below but it is understood that these alternatives
may be eliminated for further consideration due too logistical, operational or “other” currently
unknown reasons and that other opportunities may be developed and explored by the Project
team.
7.1 Transfer of Conveyance to 27” Steel Pipeline
This alternative involves abandonment of the 24” RCP and transfer of its conveyance to
the 27” steel pipeline by pressurizing the 27” pipeline via the addition of pumps. Work
involved would include preparation of a planning level hydraulic analysis to determine if
the 27” pipe could handle the increased pressure of both the 24” and 27” and the
estimated horsepower associated with the increased carrying capacity of the 27” pipe.
P&P sheets will be prepared to show the hydraulic gradeline to support the combined
flow of both the 24” RCP and 27” steel pipes and an evaluation of existing electric
service to support the proposed pumps.
7.2 New 24” RCP Diversion Structure
This alternative explores constructing a new diversion structure on the Poudre, down-
gradient of the existing diversion at Gateway Park to allow for a reduction in the length of
the rehabilitated 24” RCP while delivering the same conveyance. Work elements would
include analysis of the hydraulics associated with the best location for a new diversion
structure, preliminary layout of said structure and working with Hydro to prepare planning
level cost estimates to support construction.
7.3 Transfer of 24” RCP Conveyance to PVP at Inverted Siphon
This alternative explores the hydraulics associated with connecting the 24” RCP to the
PVP pipeline at the existing Inverted Siphon crossing under the Poudre. As with all
other proposed alternatives, work under this option would include a hydraulic profile of
both the 24” RCP and the existing Munroe Canal inverted siphon and tunnel. Work
would also include development of a conceptual design of the required vertical shaft or
piping that would be required to connect the 24” RCP pipe into the inverted siphon.
Lithos will be consulted to determine a conceptual design and cost for a shaft. Hydro will
be consulted for placement of a pipe; which will likely include excavation through rock.

(CDN033117).doc
7.4 Interconnects between 24” RCP and 27” Steel
This alternative explores the hydraulics associated with interconnect piping and valving
between the 24” RCP and the 27” steel. This evaluation will explore the hydraulics and
any risks or gains of providing said interconnects where the two pipelines are at or near
each other while keeping the HGL of the 24” at or below its current operating conditions.
Interconnections would also allow sections to the 24” (and 27”) to be temporarily isolated
to allow repairs to be accomplished.
Task 8 - Raw Water Rights and Conveyance
Work under this Task focuses on providing an understanding of the interrelationships between
the City’s raw water supply (i.e. water rights portfolio and conveyance) and seasonal demand
requirements.
8.1 Raw Water Right Conveyance
Stantec will work with the City water rights staff to complete assessments of the possible
impact to existing raw water rights associated with loss of conveyance between existing
diversions along the Poudre and their termination at the City water treatment facilities.
This assessment will include the feasibility and ramifications of relocating points of
diversion or reducing the amount of water diverted from the Pre-Sedimentation Basin
diversion. Also, included within the Project Team and City water rights staff will be the
possibility of acceptance by NPIC of allowing and conveying additional water through
their infrastructure (i.e. diversion structure, tunnels, siphon, and channel).
Task 9 - Risk Analysis
9.1 Risk Assessment
Using the data gathered in the above Tasks, Stantec will complete a Risk Register
assessment/review for the alternatives outlined herein and the “do-nothing” (i.e. repair
as-needed) x providing alternative. the overall The risk value assessment of each conveyance will focus on: (both in terms of infrastructure

The Risk Register will analyze each alternative using the same criteria. This will allow
an “apples to apples” comparison and the same basis on which to make a decision as to
the level of risk the City is willing to assume. This task may include other City staff
familiar with operation, maintenance, political (multi-agencies), legal (water rights) and
social impacts. The process of developing a risk register has been used with success
