This document is a detailed architectural design drawing for safety rails and stairs at the PNC Barracks in Guatemala, prepared by Ovalle Najera Arquitectos in January 2025. The technical drawing (Sheet A-45) provides comprehensive specifications for house stairs safety rails, including precise dimensional measurements, materials, and construction details.

Key technical specifications include: galvanized steel tubes (2" x 2", Gauge 19) for railings, A36 hot rolled steel sheet (3/8" thick), galvanized wedge anchors (3/8" x 3 3/4"), and welding rod electrodes. The design features a 0.90m high handrail and 1.07m high guardrail with maximum 1.20m spacing between supports. Coating specifications include Direct-to-Metal KEM Sherwin Williams white rust-inhibit primer and KEM 4000 Acrylic Alkyd Gray Enamel. The drawing shows multiple elevations and detailed views of the stair safety rail system, including post base plate details and lateral rail support specifications, with measurements and positioning precisely documented.
