No. 3 pumps. 3. Re -design the water main in Town Center Drive south of Bunker Lake Boulevard and remove the water main in the open space easement to open this parcel up for future development. 4. Install a new 1-inch service line off Town Center Drive to the wellhouse building at Well No. 5 for pump priming purposes. 5. Modify the plans for the 24-inch raw water main on the trail north of Sunwood Drive to use open cut installation rather than Horizontal Directional Drilling (HDD), with the exception of under Sunwood Drive, which will still be HDD to avoid impacting the recently reconstructed street. 6. Include trenchless installation of the water main crossing Bunker Lake Boulevard at 143rd Avenue to avoid impacts to the recent improvements to Bunker Lake Boulevard. 7. The trunk water main under 143rd Avenue will now be fully installed via open cut trench installation followed up with full depth bituminous pavement replacement due to the age and condition of the existing pavement, and to avoid reconstructing one side of the street and overlaying the other, putting the two sides of the street on different maintenance schedules. Due to construction traffic using this route for the WTP construction and maintaining access to adjacent commercial properties, phased pavement removal is anticipated to maintain a hard driving surface to the greatest extent possible. Final construction plans and specifications have been completed and are ready for City authorization to bid the proj ect. A copy of the title sheet is attached for reference. A full set of plans are not attached to prevent bidders from using those plans to bid the project, which can result in bids that do not reflect plan revisions that are issued through addenda only to plan holders that purchase plans through QuestCDN. Notification: Bids will be advertised in Finance and Commerce and in the Anoka Union Herald on Friday, September 29, and on Friday, October 6, 2023. Bids will also be advertised and managed online on QuestCDN. Observations/Alternatives: Observations: Bids are proposed to be opened at 10 AM on November 1, 2023. Staff then proposes to request City Council approval of a construction contract to the lowest responsible bidder on November 14, 2023. The current bidding environment for utility projects is very competitive. Material shortages have eased recently but Staff and SEH recommend bidding this project this Fall to allow the awarded contractor the Winter months to order their materials so the materials are available when the contractor is ready to start work in the Spring of 2024, and so the best bid prices can be obtained due to the long lead time for ordering materials. Alternatives: Alternative #1 — Motion to adopt Resolution #23-237 approving plans and specifications and authorizing advertisements for bids for Improvement Project #21-08, Water Treatment Plant Trunk Watermain Improvements.
