About this file
This is a Site Demolition specification document for the Salt Lake School District's Nibley Park Elementary School project. The specification outlines the complete scope of demolition work required within designated demolition limit lines, including removal of sidewalks, curbs, paving, concrete slabs, utility lines and meters, fencing, building structures, trees and stumps, underground structures such as septic tanks and basements, and paint obliteration. The contractor must submit a proposed demolition schedule and methods for review prior to work commencement, coordinate utility shut-offs and capping, and obtain a Demolition Permit and Utility Disconnection Permits from the City and utility companies. A mandatory pre-bid site visit is scheduled for Tuesday, May 26, 2026 at 9:00 A.M. at Nibley Park Elementary School located at 2785 South 800 East, Salt Lake City, Utah 84106, with contractors required to attend and meet in the northeast parking lot; failure to attend on time will result in bid disqualification.
The specification prohibits the use of explosives and requires contractors to implement pollution controls through water sprinkling and temporary enclosures to minimize dust and debris while complying with environmental protection regulations. Contractors must conduct operations to ensure safe passage around the demolition area, prevent injury to adjacent buildings and structures, promptly repair any damage caused by demolition operations, and avoid interrupting existing utilities serving occupied facilities without written authorization. All excavated areas associated with substructure removal must be backfilled with well-graded granular material not exceeding 2 inches in size with no more than 15 percent passing a #200 sieve, placed in maximum 8-inch loose lifts and compacted to 95 percent of Maximum Laboratory Density per ASTM D 1557-78. The contractor is responsible for removing all debris and disposing of demolished materials in a legal manner, with overhead utility line removal and relocation to be performed by the respective utility companies at the Owner's expense.
