RECOMMENDATION
Staff recommends that the City Council approve Change Order No. 1 to the Standard Agreement and General Conditions Between Owner and General Contractor/Construction Manager (Construction Contract) with Dick Anderson Construction, Inc. (DAC) for the W.O. 19-12: West End Reservoir (WER) Project in the amount of $408,352.64.
BACKGROUND (Consistency with Adopted Plans and Policies, if applicable)
On December 11, 2023, City Council approved a Construction Contract with DAC for the WER Project in the amount of $153,211.35. This initial contract Guaranteed Maximum Price (GMP) allowed the Project Team to begin dewatering the reservoir site through rental of temporary pumping equipment and purchase of permanent dewatering equipment.
Change Order No. 1 now under consideration would furnish a complete electrical equipment Unit Substation including medium voltage metal enclosed load interrupter switchgear, a liquid filled power transformer, and a switchboard for future installation at the Billings WE Raw Water Pump Station (RWPS) site. The equipment will be installed under a future change order to the Construction Contract. The Project Team consisting of City Staff, HDR Engineering and DAC received and evaluated pricing obtained through a public bidding process from Yellowstone Electric Co., Gray Bar, and Colstrip Electric Co. The pricing on a Unit Substation from Colstrip Electric was determined to be the best value for the City.
With lead time on this equipment at 40 weeks, procuring it ahead of final design and GMP development for the pump station is critical for maintaining the overall project schedule, including start-up of the West End Water Treatment Plant. The amount presented at this time is a GMP to procure electrical equipment for the WE RWPS.
