BACKGROUND: On February 21, 2023, the City Council approved the plans and specifications for the Old Village Phase 7 Street and Utility Improvements and authorized staff to advertise the project for bids. The improvements include the extension of sanitary sewer service, construction of a lift station, replacement of existing watermain, and the reconstruction of Legion Avenue south of 30th Street with storm sewer improvements. The Project was advertised on QuestCDN.com and in the Stillwater Gazette in accordance with the Minnesota Competitive Bidding requirements. PROPOSAL DETAILS/ANALYSIS: Bids were received and opened electronically on March 23, 2023. The City received 3 bids for this project, with Minger Construction Company providing the lowest base bid and combination of alternate bids. Full results can be viewed in the engineer’s letter of recommendation attached. The proposed sanitary sewer lift station was designed two different ways and bid as alternate line items to determine actual costs for each option. The lift station design for Alternate A is a prefabricated fiberglass structure with a concrete bottom while the lift station design for Alternate B is a city standard concrete wet well and separate concrete valve vault. In order to complete the project the City Council must award the Base Bid + Alternate A OR the Base Bid + Alternate B. Contractor references for Minger Construction Company were reviewed and verified. The City Engineer and the design engineer (SEH) are therefore recommending that the City award the contract to the lowest responsible bidder, Minger Construction Company for the Base Bid + Alternate B (concrete lift station structure) for a total amount contract amount of $2,296,658.75 as outlined in the attached letter. As a part of this award staff is requesting Council to provide the City Administrator authorization to enter into a material testing contract for the construction geotechnical work in the not-to-exceed amount of $28,000. Staff is receiving proposals from Braun Intertec and AET, Inc. to complete the work and will provide a recommendation on who to enter into contractor with to the City Administrator once a review is complete. Additionally, staff is requesting Council to provide the City Administrator authorization to enter into a construction services contract with SEH in the amount of $235,700 to provide construction staking, construction observation, and technical support for the project. These fees are included in the total project budget presented in the fiscal impact section.
