About this file
This is a drawings file related to an RFP issued by the State of Utah Division of Purchasing, conducted by the Division of Oil, Gas, and Mining, for the Wattis Mine Coal Fire Abatement project in Carbon County. The project scope involves sealing five mine openings, eleven subsidence openings, fifteen exhaust vents and air intakes, and twenty-seven open cracks at an abandoned coal mine. Work methods include excavation and grading, drilling shallow borings, and use of a walker "spider" excavator with appropriate attachments to suffocate an active underground coal fire. A mandatory in-person site visit is required on Tuesday, 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 approximately four hours and will involve driving and hiking over rugged terrain, with high-clearance four-wheel-drive vehicles recommended. Attendance by an authorized representative is mandatory for bid eligibility, and bids from firms not on record as attending the entire meeting will be considered nonresponsive. Bidders are advised to supplement the site visit by examining the project independently, though entry into the mines themselves is prohibited due to hazardous conditions.
The drawings file serves as a supporting exhibit to the RFP and provides technical documentation of the project site conditions and specifications. This file contains the visual representations and technical details necessary for bidders to develop accurate proposals and understand the scope of work involved in this specialized abandoned mine closure project. No additional pricing terms, set asides, incumbent information, or funding details are specified within the drawings file itself.
