UAS_Delineated_Cracks.kmz

This is a supporting exhibit file in the form of a KMZ (Keyhole Markup Language) geospatial file related to an RFP issued by the State of Utah Division of Purchasing, conducted by the Division of Oil, Gas, and Mining. The project involves the sealing and closure of an abandoned coal mine in Carbon County, Utah with an active underground coal fire. The scope of work requires sealing five mine openings, eleven subsidence openings, fifteen exhaust vents and air intakes, and twenty-seven open cracks through excavation, grading, shallow boring drilling, and operation of specialized walker "spider" excavator equipment with appropriate attachments. 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 (GPS coordinates: 39.536251, -110.816029). The site visit is expected to last four hours and will involve driving and hiking over rugged terrain; high-clearance four-wheel-drive vehicles are recommended. Attendance at the entire pre-bid meeting by an authorized representative is mandatory, and bids from firms not on record as attending will be considered nonresponsive. Bidders are encouraged to supplement the mandatory meeting by examining the project independently, though entry into the mines is prohibited due to hazard risks.

The KMZ file serves as a geospatial data file providing delineated crack locations identified through Unmanned Aerial System (UAS) technology, enabling bidders to visualize the specific cracks and other features requiring sealing at the mine site. This file supports bidder evaluation and cost estimation for the specialized abandoned mine closure work, which differs significantly from standard construction due to its unique hazardous conditions and circumstances.
