Midlothian Mines Headstock Replacement

Chesterfield County is soliciting bids for the Midlothian Mines Headstock Replacement project, which involves the construction of a headstock replica at Midlothian Mines Park in Midlothian, Virginia. The scope of work includes field verification of existing foundations, removing and welding steel knife plates, and the fabrication and erection of a new heavy timber headstock with custom steel connection plates and hardware. Additional requirements include applying wood-preservative treatments, installing copper flashing on horizontal timber members, and refurbishing and reinstalling existing winder wheels. All work must adhere to AISC and AWS standards, with specific quality control and inspection protocols required at both the fabricator's facility and the project site.

If the contract exceeds 500,000 dollars, the awarded contractor must provide performance and payment bonds for 100 percent of the contract price within 15 calendar days of the notice of award. The contractor is required to provide a project manager available by cellular phone and must submit a preliminary schedule within 10 days of the agreement. Payment is processed through the County's preferred ePayables program or by check, with standard payment terms of 30 days after receipt of an accurate invoice.
