About this file
This technical document is a detailed architectural design specification for a standard semi-permanent awning structure for a U.S. Embassy project in Guatemala. The design features a curved, galvanized steel truss frame with multiple segments spanning 20.00 meters, supported by precast concrete semi-buried counterweights. Key structural specifications include high-resistance galvanized GHT tube/plates with Grade 72 structural strength (72,000 PSI), zinc coating Z180, and bolted connections using A325 or G60 threaded rods.
The awning includes white, blackout polyester canvas with PVC coating (24 oz/yd2) that has UV protection, fungus retardant, and flame-retardant properties. Structural elements feature x-bracing, lateral wind bracing, and galvanized stringers. Additional safety features include multiple Franklin spike lightning rods with delta-type ground system connections. The counterweights are specified with 3,000 PSI concrete, 40,000 PSI reinforcement steel, and are prefabricated with dimensions to support 1.5-2 tons per base. A sea container is noted as being present on-site, with potential requirements for obstacle removal or relocation.
