About this file
This is a project specification document for a federal roofing contract at the Charleston FLETC (Federal Law Enforcement Training Center) facility. The project involves urethane/silicone restoration work over modified bitumen roofing on Building 46's upper roof, covering 10,500 square feet at 2000 Bainbridge Avenue, North Charleston, South Carolina.
The scope requires three-step material application: GacoFlex U9101 Aromatic Urethane base coat applied at 1.5 gallons per 100 square feet, Gaco HER Urethane Flashing Grade applied to all flashing seams, corners, and laps, and GacoFlex S4200 Silicone top coat applied at 1.25 gallons per 100 square feet. The work must comply with specification ASP-U91S42-36-15. A critical requirement is that the 15-year leak-free warranty is available exclusively to Gaco Licensed Applicators, meaning the contractor must maintain proper licensure with Gaco. The contractor is to be determined (TBD), and inquiries regarding the project should be directed to Christopher Seay, Area Manager for North Florida and South Carolina at ACS - Gaco (Amrize Building Envelope Division) at 615-830-5044.
