Stoneybrook Drive Retaining Wall Replacement

The City and County of Broomfield is soliciting bids for the Stoneybrook Drive Retaining Wall Replacement project (Project #24T0030), a comprehensive infrastructure improvement initiative located near Aspen Creek K-8 School and Discovery Church. The project involves removing an existing wood retaining wall and replacing it with a Redi-Rock retaining wall, covering 424 square feet with 67 cubic yards of gravel backfill and associated site restoration work. Contractors must provide comprehensive services including wall removal, earthwork, construction surveying, tree protection, seeding, and an optional add alternate for cattail removal from the adjacent water area. Bidders are required to complete a Qualification of Bidders form demonstrating trade practices, environmental work experience, and technical capabilities. The bid submission deadline is August 15, 2025, at 2:00 pm through the Rocky Mountain E-Purchasing System, with questions due by August 11, 2025, at 2:00 pm. The anticipated Notice to Proceed date is October 1, 2025, with a contract duration of 105 calendar days and a two-year warranty period.

The contract does not specify specific set-aside designations for disadvantaged enterprises, but requires bidders to demonstrate financial resources and technical experience. Bid security of 5% is mandatory, and performance and payment bonds are required for projects over $50,000. The total base bid is approximately $20,000, with a $20,000 force account allowance for potential additional work. Contractors must hold a Class C contractor's license and obtain a no-fee Public/Private Improvement (PPIP) permit. The city will award the contract to the lowest responsible and responsive bidder, reserving the right to reject any or all bids. Liquidated damages are set at $500 per day for contract delays, and the bid remains valid for 90 days after opening. Environmental considerations include obtaining necessary permits from the Army Corps of Engineers and Colorado Department of Public Health and Environment, with specific requirements for cattail removal and site restoration.
