9-Wattis Coal Mine Fire 2 Final Specs FULL FINAL 20261007.pdf

This document is a final specification for abandoned coal mine closure work conducted by the State of Utah Division of Oil, Gas, and Mining. The project involves sealing five mine openings, eleven subsidence openings, fifteen exhaust vents and air intakes, and twenty-seven open cracks at an abandoned coal mine in Carbon County, Utah. Work will be performed through excavation and grading, shallow boring drilling, and operation of specialized equipment including a walker "spider" excavator to suffocate an active underground coal fire. A mandatory in-person site visit is required on October 20th at 10:00 am at the northwest parking lot located at the intersection of UT-10 S Carbon Avenue and Ridge Road in Carbon County, with GPS coordinates 39.536251, -110.816029. The meeting is expected to last four hours and will involve driving and hiking over rugged terrain; high-clearance four-wheel-drive vehicles are recommended. Bids from firms not recorded as attending the entire mandatory site visit will be deemed nonresponsive. Bidders are encouraged to supplement the pre-bid meeting by independently examining the project, though entry into the mines themselves is prohibited due to hazard concerns.

The specifications emphasize that abandoned mine closure work differs substantially from standard residential or commercial construction and requires specialized expertise in unusual and unique conditions. The project's specialized nature necessitates the mandatory pre-bid attendance requirement, ensuring that only qualified contractors with appropriate knowledge and understanding of the work scope submit bids. This procurement falls under Utah Procurement Rule R33-101-13 regarding pre-bid conferences and site visits, which mandates in-person attendance by authorized vendor representatives.
