About this file
This is a design specification document for the City of Detroit Office of Contracting and Procurement regarding temporary gate systems to close Ridge Road between McNichols Road and the Rouge River bridge during high-water flood events. The project, identified as PW-7069, includes installation of double swing barrier gates at two locations: the Ridge/McNichols intersection and the Ridge/Riverdale intersection. The design specifications detail gate post placement, receiving posts, temporary closure gate configurations, and foundational requirements at each site. A mandatory pre-bid walk-through is scheduled for Monday, February 16, 2026, at 3:00 PM EST at 16706 Ridge Road, Detroit, Michigan 48219, and all firms wishing to bid must attend this site visit.
The technical drawings specify double swing barrier gate systems by Tiger Gates (Model 14020) or approved equivalent, with zinc-plated finishes, sealed hinges, and 1/4-inch grade steel chains for securing gates in open or closed positions. Each location requires three three-foot steel chains, galvanized steel pipe receiving posts in varying diameters, concrete foundations, warning signage, and associated site work including brush clearing and sidewalk removal and replacement where applicable. The specifications include detailed measurements, coordinate references, and notes regarding existing utility considerations and site-specific installation requirements at each gate location.
