Docusign Envelope ID: 06777E90-FF95-87E3-8300-713633A1DC86 PASSED, ADOPTED, AND APPROVED by the City Commission of the City of Bozeman, Montana, at a regular session thereof held on the 28TH day of April, 2026. ___________________________________ JOEY MORRISON Mayor ATTEST: ___________________________________ MIKE MAAS City Clerk APPROVED AS TO FORM: ___________________________________ GREG SULLIVAN City Attorney Docusign Envelope ID: 06777E90-FF95-87E3-8300-713633A1DC86 406-586-8834 ■ 800-865-9847 (fax) ■ 1283 N. 14th Ave; Ste 101 ■ Bozeman, Montana 59715 ■ www.dowl.com April 9, 2026 Mr. Kellen Gamradt City of Bozeman P.O. Box 1230 Bozeman, MT 59771 Subject: Riverside Lift Station and Force Main – Change Order 2; Recommendation for Approval Dear Mr. Gamradt: Please see the following change order for the Bozeman Riverside Lift Station and Force Main project. This change order is the result of four field orders, miscellaneous addition, and reconciliation of final installed quantities. CO2-1: The door hardware and manual lock package was revised to include the City’s preferred Trilogy electronic lock set. This cost $1,495.62 CO2-2: The electric meter base was upsized from a 100 A base to the 200 amp base required by Northwestern Energy on any new commercial service. This resulted in an increase in cost of $2,682.75. CO2-3: The generator arrived with a weather-proof enclosure that was not needed for the interior generator installation. The enclosure was readily removed to allow the intended connections to the cooling air exhaust louver. However, some custom fabrication of a few engine exhaust fittings was required and delays incurred waiting for parts. This work increased project cost by $6,777.01. CO2-4: The City Water and Sewer Department requested the air release valve in the building discharge to the outside atmosphere rather than into the floor drain. This resulted in an increase in cost of $1,315.68. CO2-5: One additional manhole lid had to be swapped with waterproof lid, as the previous change order included moving one of the manholes into the floodplain to avoid an existing watermain found in a different location than anticipated. This resulted in an increase in cost of $1,456.68. CO2-6: The final reconciliation of quantities is included in this change order. The amount of gravity sewer increased, while other quantities decreased from the bidding to construction. This resulted in a savings of $4,032.50 The increase in the contract amount for the six items on this change order is $9,695.24. The requested increase in contract time includes delays related to Northwestern Energy arriving to relocate an existing electrical line as a required part of the project. This delayed excavation for the building foundation and below-grade piping. Additional delays were experienced waiting for delivery of the larger meter base for change order item CO2-2 and delays incurred modifying the generator engine exhaust as part of CO2-3. A total of 92 additional calendar days are recommended for an adjusted substantial completion date of April 20. We further recommend approval of this change order for the amount of $9,695.24. Docusign Envelope ID: 06777E90-FF95-87E3-8300-713633A1DC86 Page 2 of 2 The project is complete with no further adjustments in cost anticipated at this time. The total increase in project construction cost from the bid price of $1,782,351 is approximately $19,265. Further, the engineering services budget should have in excess of $100,000 remaining at project completion that will not need to be expended for the project. Overall, the project costs will end approximately $1 million under the estimated project costs from before bidding. Please let us know if you have any questions. Sincerely, DOWL Kevin R.

The City of Bozeman initially requested relocation of the primary power 06/12/2025. NorthWestern Energy was generally unresponsive in scheduling relocation of the power. CK May completed all work at the lift station site that was not hindered by the existing location of the primary power 08/01/2025. To note, with the power not relocated during the wet well installation, some inefficiencies were forced. One such example is that CK May would typically have installed the piping from the wet well through the building floor at the time of installation of the wet well which required temporary backfill and re-excavation. The unknown date of primary power relocation also created challenges with scheduling of crews and subcontractors. This primarily affected the concrete subcontractor and delayed the foundation pour schedule. Eventually, NorthWestern Energy related the primary power 08/14/2025. CK may crews were able to remobilize and begin work 08/25/2025. Due to the delays in the project cause by NorthWestern Energy's relocation of the existing primary power, CK May requests 30 calendar days be added to the contract time. No increase in contract value is requested due to the delay. P.O.
