appurtenances. • Electrical systems consist of electrical circuits and controls including lighting, power, instrumentation and controls, and associated conduit and wiring. • A standby generator sized to meet emergency and load management electrical requirements. • Sitework includes grading, seeding, influent water main, sanitary sewer, storm sewer, piping appurtenances, an asphalt access road and parking lot, and a stormwater filtration basin. AE2S completed plans and specifications in January. Advertisements for bids were published in the Anoka County Union Herald and in Finance & Commerce on Friday, January 27, and Friday, February 3, 2023. The project was also advertised and bid electronically through QuestCDN. Three addenda were issued while plans were advertised for bids. Three (3) bids were received and publicly opened on March 9, 2023. Attached is the project bid tabulation. Notification: Notifications are not required for this case. Time Frame/Observations/Alternatives: Observations: The WTP trunk watermain improvements, which are needed to connect the six (6) municipal water wells in The COR to the WTP and to push treated water out to the water supply distribution system, are proposed to be bid in the Summer/Fall of 2023 with construction anticipated to occur in 2024. Construction of the trunk watermain improvements is estimated to take 3 to 4 months to complete. Constructing these improvements in 2024 (or early 2025) will allow the WTP to be commissioned in June of 2025 when peak water use season typically begins. A non -mandatory pre -bid meeting was held on February 15th. Representatives from all 3 of the bidders attended. During that meeting several items were discussed including that the bidders recommended allowing more than 24 months for completion of construction from the date a contract is awarded. The bidders stated that it generally takes 3 to 4 months to execute contracts with their subcontractors and to order materials before physical construction can begin in earnest. This only leaves the contractor 20 to 21 months to construct the WTP, meaning the contractors will likely increase their bids to account for the risk of financial penalties for not meeting specified completion deadlines. Staff discussed the contractor's comments with AE2S and an addendum was subsequently issued to include an alternate bid to extend the project completion deadline by 4 months at an overall project cost savings to the City. Below are the base bid and alternate bid project completion deadlines. Base Bid Completion Dates: 1. Substantial Completion by May 1, 2025. 2. Final Completion by August 1, 2025 Bid Alternate No. 1 Completion Dates: 1. Substantial Completion by September 1, 2025. 2. Final Completion by December 1, 2025 On March 21, 2023, the Public Works Committee considered a recommendation to the City Council to accept the three (3) bids and award a contract for construction to the low bidder, Magney Construction, LLC. During the meeting it was discussed whether bid alternate #1 should be accepted. After discussing the amount of-$50,000 submitted by Magney Construction for bid alternate # 1, and the fact that the required inspections during the additional 4 months may cost more than $50,000 and would put a strain on existing infrastructure, the Public Works Committee passed a motion to recommend City Council acceptance of bids and award of a construction Contract for Improvement Project #21-09, Centralized Water Treatment Plant, to Magney Construction, Inc., rejecting Bid Alternate # 1.
