Benchmark Service: Construction Phase Services
Issue: Corroded system fasteners were delivered to the job site with the intent to incorporate into the new roof system.
Solution: Benchmark directed the Contractor to remove the fasteners from the job site to prevent inadvertent use, and obtain and properly store new fasteners.
Possible Impact: If installed, these fasteners will continue to corrode, promoting corrosion to fastener seam plates and the steel deck, ultimately resulting in areas of failed wind uplift resistance.
