Midlothian Mines Headstock Replacement

Chesterfield County is soliciting bids for the Midlothian Mines Headstock Replacement, a project to construct a headstock replica at Midlothian Mines Park. The scope of work includes field verification of existing foundations, removing and welding new steel knife plates, fabricating and erecting a new heavy timber headstock with custom steel connection plates, and installing copper flashing. Additionally, the contractor must refurbish and reinstall existing winder wheels and apply specific wood-preservative treatments. All steel components must be hot-dipped galvanized according to ASTM standards, and timber must be kiln-dried Southern Pine with UC5C pressure preservative treatment. The contract will be awarded to the lowest responsive and responsible bidder based on a lump sum bid. Bids are due by December 17, 2026, and must be submitted via hard copy or the County's eProcurement system. A non-mandatory pre-bid conference is scheduled for November 19, 2026. Bidders must provide a bid bond equal to 5% of the total bid price, and if the bid exceeds $500,000, both performance and payment bonds of 100% of the contract price are required. Payment is typically made within 30 days of receiving an accurate invoice, with a 5% retainage applied to monthly estimates. The project is subject to various regulatory compliances, including federal, state, and local environmental and safety regulations, as well as Equal Employment Opportunity requirements.
