About this file

This is an Asbestos Survey and Assessment Report prepared for Granite School District regarding West Kearns Elementary School, located at 4900 South 4620 West in Kearns, Utah. The survey was conducted by Air Quality Consulting, LLC, with samples collected on May 27, 2026, and June 1-2, 2026, and tested at Eurofins Reservoirs in Denver, Colorado. The assessment identified asbestos-containing materials (ACM) in multiple building components, including vinyl flooring tiles, wall vinyl, carpet mastic, window glazing, and various mastics throughout the facility. Specific ACM findings include approximately 13,940 square feet of hallway vinyl tile containing 8% Chrysotile mastic, 43,450 square feet of carpet mastic containing 10% Chrysotile, 4,385 square feet of 9"x9" vinyl tile containing up to 17% Chrysotile mastic, 1,710 square feet of tan wall vinyl containing 15% Chrysotile, and various wall vinyl installations ranging from 4% to 20% Chrysotile content across 262 to 1,700 square feet each. Additionally, 400 square feet of window glazing contains 0.25% Chrysotile. The report notes that door cores, roofing materials, and boiler components were not sampled and require destructive testing, and areas under the foundation and within wall and ceiling cavities remain inaccessible but are known to potentially contain transite pipe or thermal system insulation.

The findings from this survey support the pending demolition and abatement project outlined in the related Invitation for Bids. The procurement seeks qualified licensed Demolition Contractors (S310) and licensed Abatement Contractors to execute complete abatement and demolition services according to project specifications and drawings. A pre-bid meeting is required for prospective bidders, with award recommendation scheduled for the July 7, 2026 Granite School District Board meeting, followed by final award issuance upon board approval. The comprehensive identification of ACM locations and concentrations throughout the facility provides the baseline documentation necessary for contractors to develop compliant abatement and demolition plans in accordance with applicable OSHA regulations and Utah state requirements.
