RECOMMENDATION
Staff recommends that City Council award a contract for W.O. 22-10, Alkali Creek Water and Sewer Extension, to Western Municipal Construction in the amount of $3,875,064.00.
BACKGROUND (Consistency with Adopted Plans and Policies, if applicable)
W.O. 22-10, Alkali Creek Water and Sewer Extension, will extend a 12-inch diameter water main and a 21-inch diameter sanitary sewer main along Alkali Creek Road from the intersection of Strawberry Avenue and Alkali Creek Road to the northwest approximately 3,900 feet. The water and sewer extension will terminate at the property line of the proposed Timbers Subdivision, First Filing, which will allow the subdivision to connect to City services. This water and sewer extension will also be part of the "backbone" of the water and sewer infrastructure needed to serve the Inner Belt Loop Corridor. The water and sewer extensions are also recommended in the Water and Wastewater Master Plans.
The project was advertised on January 21, January 28, and February 4, 2022, in the Yellowstone County News and on the City's website. Bids were opened on February 8, 2022, and two bids were received. Western Municipal Construction submitted the lowest, responsible bid.

ALTERNATIVES
City Council may:
- Award W.O. 22-10, Alkali Creek Water and Sewer Extension, to Western Municipal Construction in the amount of $3,875,064.00; or,
- Do not award a contract and reject all bids. If the project is not awarded, the Timbers Subdivision, First Filing, will not have City services and will have to develop in the County. Also, as the Inner Belt Loop develops, these mains will not be avaiable for development along the corridor.
FISCAL EFFECTS
The following bids were received:
The project was budgeted in FY 22 using water and wastewater funds. The water portion of the project is within budget.
The sewer portion of the project ($2,885,515) was budgeted at $2,000,000 and the shortfall of $885,515 in wastewater funds will be used from cost savings from the fats, oils, and grease (FOG) receiving station project. The FOG project scope was reduced due to modifying the approach and it can be constructed with the remaining funds. Engineering staff reviewed the sewer bid tabulations and unit prices, and generally sanitary sewer items were slightly above budgeted estimates, except for construction dewatering. The construction dewatering bid cost noted in both bids was substantially more than estimated due to the wet, soft soils present at the site that are difficult to dewater combined with the 25-foot deep sewer installation.
