About this file

This is a specification document for wood composite fencing materials and installation procedures for the City of South Salt Lake's 1300 East Fence Project, with bids due by 4:00 p.m. on August 14th, 2026. The project scope includes furnishing and installing new wood composite fencing using Trex Fencing's Seclusions Privacy Fence System, which is manufactured by Trex Fencing located in Provo, Utah. The fence system is available in multiple heights ranging from 2 feet to custom heights up to 11-12 feet, with surface textures offered in smooth finish and four color options: Saddle, Winchester Grey, Woodland Brown, and Charcoal Black. Components include fence posts, various post cap styles (Pyramid, Flat, Crown), top rails, aluminum bottom rail inserts, pickets, and fence brackets. The specifications require the fence system to withstand 130 MPH steady wind and 147 MPH gusting wind loads. Installation requirements include spacing posts maximum 8 feet on center, drilling post holes to 12 inches diameter with the post bottom located 30 inches below grade or below the frost line, whichever is greater. The manufacturer provides a 25-year residential warranty or 10-year commercial warranty covering checking, splitting, splintering, rotting, structural damage from termites, and fungal decay.

The wood composite material must meet specific performance standards including abrasion resistance of 0.01 inch wear per 1000 revolutions, hardness of 1124 pounds, flame spread rating of 80, and termite resistance rating of 9.6. The material specifications include fastener requirements of 1-5/8 inch galvanized or corrosion-resistant coated steel with 163 pounds per inch nail withdrawal and 558 pounds per inch screw withdrawal. Concrete foundation requirements specify minimum 2500 PSI compressive strength at 28 days with 3 to 5 inch slump, conforming to ASTM C 94. No substitutions to the specified Trex Fencing manufacturer are permitted unless approved through formal substitution procedures. A 5% Bid Security is required, and plans and specifications are available from the City Recorder, Ariel Andrus, at aandrus@sslc.gov as of August 3, 2026. No pre-bid meeting or public bid opening is scheduled for this project.
