Re: Lift Station 36 Professional Services
Meeting Date: 8/4/2025
BACKGROUND: The City of Kalispell brought Lift Station 36 online in 2008, which is located
just north of the Stillwater River on US Highway 93, west of the highway. At the time of the
original construction, the design peak pump rate was determined to be 510 gallons per minute for
Silverbrook and other proposed upstream developments. The lift station is nearing capacity as
development continues to expand in the service area. The upgrade to Lift Station 36 will include
approximately 700 feet of new 10-inch force main. The new lift station will be a 1,100 gallon per
minute triplex system utilizing self -priming pumps, in a free-standing structure per the City of
Kalispell Standards for Design and Construction.
City engineering staff completed the civil design for the project, but solicited for additional
professional services to cover structural, electrical and mechanical design components for the lift
station in March of 2024. Four statements of qualifications were reviewed from AE2S, HDR,
RPA, and TD&H. A four -person selection committee was convened to review and score the
statements of qualifications. Ultimately, AE2S was selected and proposed services were
negotiated for a Task Order No. 1 to carry the project through design, at $53,329. Following the
city's policies specified for professional services in the City's Procurement Manual, the contract
and Task Order No. 1 were executed by the City Manager on June 3, 2024.
Public Works staff originally anticipated completing the construction inspection engineering
services in-house for the project. With a vacancy in the department and resources assigned to
different projects, we are looking at contracting for construction engineering. Since AE2S
participated in design efforts they are the most qualified firm to support construction oversite for
the project. A second Task Order was requested to provide construction engineering services
throughout the anticipated 6-month build. The cost of these additional services were negotiated
to $144,332.00, which requires Council approval.
REQUESTED ACTION: Motion to approve Task Order No. 2 for AE2S to provide
professional construction engineering services for the Lift Station 36 Replacement project at a
cost not to exceed $144,332.
FISCAL EFFECTS: Adequate funds have been allocated for the Lift Station 36 Replacement
project in Sewer Fund Budget Line Item 95310-454-430630-961 and Sewer Impact Fee Line
Item 95311-454-430635-961.
ALTERNATIVES: As suggested by the City Council.
