This is a Design-Build project to replace the roof on a historic, one-story steel and concrete building of approximately 68,986 square feet. The work involves removing the existing built-up roof and installing new assemblies: a 3-ply SBS-modified roof on the barrel section and a 90-mil EPDM roof on the three lean-to sections. The location for performance is Building 10571. A site visit is scheduled for June 8 at 1:00 PM local time. No budget amount is specified.
