E2. Approve Change Order for Four Mile Drive ProjectCITY OF KALISPELL MEMORANDUM To: Doug Russell — City Manager CC: Susie Turner, PE — Public Works Director From: Keith Haskins, PE — Deputy Director Public Works Re: Schedule 2 — Grandview Lift Station and Four Mile Drive Force Main Meeting Date: 6/17/2024 BACKGROUND: In June of 2023, Council awarded Schedule 2 of the Grandview Lift Station and Four Mile Drive Force Main Project to LHC Inc. for a contract price of $1,593,220.39. Schedule 2 is for construction of 4,312 linear feet of 10-inch force main with 1,190 installed via horizontal directional drilling. Construction of this schedule started in April of this year and is currently at 66% complete (based on cost of work). Multiple sources were used to fund the project including a State Revolving Fund Loan, ARPA Local Fiscal Recovery Funds, City Sewer Rates, and City Sewer Impact Fees Below is a breakdown of the current contract price by schedule: Sch 1 - Western Municipal —Bid $ 3,874,000.00 - WM — Change Order 1 $ 67,756.10 - WM — Change Order 2 $ 4,055.58 SCH 1 TOTAL CONTRACT = $ 3,945,811.68 Sch 2 — LHC Inc. —Bid $ 1,593,220.39 SCH 2 TOTAL CONTRACT = $ 1,593,220.39 Total (Sch 1 + Sch 2) = $ 5,539,032.07 Budget (Construction + Contingency) = $ 6,271,570.00 Remaining Budget = $ 732,537.93 The original contract approach for replacement of asphalt on the project was to patch back only the utility trench line for Four Mile Drive. A plan view of a portion of the plans showing the proposed utility patch and typical detail of the utility patch as bid are provided in Figures 1 and 2 on the following page. Change Order 1 for Schedule 2 is recommended by staff to complete additional milling and paving, rectify prices for valves used on the project, and to account for installation of insulation required to protect the force main from freezing in a realignment to avoid private utilities. 201 1st Avenue E I Phone (406)758-7720 Po Box 1997 Public Works Department Fax (406)758-7831 Kalispell, MT 59903 1 1 www.kalispell.com Doug Russell Schedule 2 — Grandview LS and 4MD Force Main Page 2 E KYA1 fi' I.

This approach would provide a uniform surface for the street, seal off the utility patches already in the roadway and complete work on a street currently identified by Public Works as needing a future Mill and Overlay. Utilizing LHC's Mill and Overlay bid costs which the City has also contracted with LHC, change order costs were negotiated. The total cost for the additional mill and overlay is $84,660. In addition to the mill and overlay, the change order takes into account a cost savings of $5,200 by switching from plug valves to gate valves on the force main. Additionally, in order to avoid some private utilities, 418 feet of the force main was installed shallower than minimum depth which required installation of insulation board. The required insulation added $23,840.78 to the change order, bringing the total cost for Change Order No. 1 (attached) to $100,300.78. REQUESTED ACTION: Motion to approve Change Order I for Schedule 2 — Grandview Lift Station and Four Mile Drive Force Main Project for an increase in the contract price of $100,300.78 for a total contract price of $1,693,521.17 and no increase in contract days. FISCAL EFFECTS: Adequate funds are available in ARPA Funds, Sewer Funds, and Sewer Impact Fee Funds budgeted for the project.
