Commission Memorandum
REPORT TO: Honorable Mayor and City Commission
FROM: Brian Heaston, Senior Engineer
Mitch Reister, Director of Public Works
SUBJECT: Authorize the City Manager to execute Task Order No. 10 of the Professional
Services Master Task Order Agreement with the firm of AE2S, Inc. providing professional engineering services for the Bozeman WTP – Sourdough Raw Water Influent Metering
Improvements 2019 project.
MEETING DATE: December 16, 2019
AGENDA ITEM TYPE: Consent
RECOMMENDATION: Authorize the City Manager to execute Task Order No. 10 of the
Professional Services Master Task Order Agreement with the firm of AE2S, Inc. providing
professional engineering services for the Bozeman WTP – Sourdough Raw Water Influent Metering Improvements 2019 project.
BACKGROUND: AE2S, Inc. provides professional engineering services on as on call basis for
the Bozeman Water Treatment Plant facility (WTP) under a Master Task Order Agreement
entered into on April 24, 2017. Task Order No. 10 attached provides professional engineering services for the Bozeman WTP – Sourdough Raw Water Influent Metering Improvements 2019
project. Services include pre-design alternatives analysis for automated flow control and
metering improvements on the Sourdough raw water supply line between the Sourdough intake
and Sourdough water treatment plant. Once a preferred automated control and metering
alternative is selected, 30% design documents and construction cost estimates will be produced.
Currently, there is no automated flow control on the Sourdough raw supply. Raw water supply is
instead manually controlled by operators at the Sourdough diversion dam itself, located
approximately 0.5 miles past the gate at Sourdough Canyon trailhead. There is no automated
meter registering Sourdough raw water flows into the treatment plant. Instead, diverted flow measurements are taken manually at a parshall flume installed at the Sourdough diversion dam.
Task Order No. 10 will produce preliminary design documents (30% design) to meter and
automate diversion of Sourdough raw water supply into the treatment plant. So doing will
provide the Sourdough raw water supply infrastructure with similar and complementary
control/metering capabilities to that of the Hyalite raw water supply infrastructure.

FISCAL EFFECTS: The approved FY20 Water Fund CIP contains item W96, funded at
$300,000, for the Sourdough Raw Transmission Main Flow Control Valve and Meter project.
Task Order No. 10 contains a negotiated fee not to exceed $39,150 to complete alternatives
analysis, preliminary design, and preliminary construction cost estimate tasks for the project. After debiting Task Order No. 10 from the W96 funding allocation, an unobligated project fund
balance of $260,850 remains for final design and construction.
ALTERNATIVES: As suggested by the Commission.

EXHIBIT B to Professional Services Agreement Dated April 24, 2017
TASK ORDER NUMBER 10
Issued under the authority of Professional Services Agreement between the City of Bozeman
and Advanced Engineering and Environmental Services, Inc. for: A range of professional and technical
services related to operations and maintenance of the City of Bozeman Water Treatment Plant and
support facilities, including but not necessarily limited to engineering design, preparation of
construction documents, project bidding, and construction administration services for various
improvement projects.
This Task Order is dated , 2019 between City of Bozeman (City) and Advanced Engineering
and Environmental Services, Inc. (Contractor).
The following representatives have been designated for the work performed under this Task Order:
City: Brian Heaston, PE, Project Engineer
Contractor: Advanced Engineering and Environmental Services, Inc. (AE2S)
Brian Viall, PE, Project Manager
SCOPE OF WORK: (attach additional sheet(s) as required)
This Task Order is for a feasibility study and technical report with recommendations in association with
improvements generally described as:
Bozeman WTP – Sourdough Raw Water Influent Metering Improvements 2019
Contractor’s Project Number: P05097-2019-014
The scope for which is generally described as follows:
Engineering
1. Review record drawings of the influent pipelines from Bozeman Creek in Sourdough Canyon and
Hyalite Creek as they enter the “Hyalite Connection Building/Sourdough Flow Control
Building.”
2. Conduct field investigations at Bozeman Water Treatment Plant (WTP) of surface conditions to
identify critical valves, potential tie-in locations, existing utilities and other appurtenances. Does
not include field-verification of subsurface conditions by exploratory excavation.
3. Draft record drawings of raw water process. Two drawings will be produced: 1) A process flow
diagram (PFD) and 2) conceptual site layout with raw water pipeline alignments. Existing
drawings will be utilized to the maximum extent possible, augmented with field investigation.
4. Review alternatives for installation of flow metering on the raw water influent pipeline from the
Sourdough Creek Intake. The following alternatives will be evaluated:
a. Multi-point insertion ultrasonic system on the Sourdough raw water pipeline elbow in the
Raw Water Control Building. Evaluate the accuracy of this approach.
b. Magnetic Flow Metering in an expansion of the existing Raw Water Control Building.
c. Hydraulic Flow Control Valve (Cla-Val) with upstream screening (see flow control valve
alternatives, below.
5. Evaluate flow control valve installation alternatives for Sourdough raw water.
162
a. Automatic Backwashing Strainer (ABS) ahead of modulating butterfly valve or hydraulic
flow control valve (Cla-Val)
6. Evaluate the impact (if any) of metering and flow control alternatives on Hyalite flow control and
flow measurement.
7. Draft conceptual drawings of piping modifications to accommodate proposed improvements.
8. Meetings
a. Kickoff Meeting
b. Technical Memorandum Review Meeting.
Documentation
1. Technical memorandum of recommendations, including the following:
a. Existing raw water system evaluation.
b. Summary review of flow metering alternatives with Engineer’s recommendation of
best alternative.
c. Summary review of control valve alternatives with Engineer’s recommendation of
best alternative.
d. 30% drawings of process and site-work modifications to accommodate recommended
improvements.
e. Engineer’s Opinion of Probable Construction Cost (EOPCC) to complete work.
f. Estimate 15 to 20 pages total document length. Includes drawings, tables, opinions
of cost, etc.
2. Revised record drawings of raw water process to show the following:
a. Process flow diagram (PFD) of raw water process.
b. Site piping alignments on site background.
COMPENSATION:
The total cost for the engineering, documentation, and materials associated with this Task Order is
