Concrete Stair Cross Section With 250mm Tread 150mm Riser Detail

This concrete staircase cross-section CAD drawing presents a detailed structural reinforcement layout with precise construction measurements and elevation detailing for multi-level building projects. The drawing includes staircase cross-section views showing a tread size of 250 mm and a riser height of 150 mm, with accurate reinforcement placement and structural support conditions. It illustrates foundation column connection, stair flight alignment, landing support, and beam interface detailing for safe load transfer in RCC construction systems. The AutoCAD file provides a complete sectional representation of stair geometry with reinforcement bar positioning, slab integration, and step-by-step structural alignment suitable for residential and commercial buildings. It also includes dimensional references, vertical level marking, and construction detailing for proper execution on site. This CAD drawing is highly useful for architects, civil engineers, builders, and structural designers for preparing staircase reinforcement layouts and construction documentation. It supports AutoCAD drafting, Revit modeling workflows, and 3D structural visualization for accurate staircase design implementation with clear technical specifications and construction-ready detailing.
