Structural Staircase Drawing with RCC Sections and Step Details

This structural staircase drawing presents a detailed RCC staircase layout with complete plan and sectional information prepared for construction execution. The drawing includes a structural layout for the staircase, detailing with clear marking of columns, beams, landings, and step numbering. Section A A shows the staircase from plinth level to first mid landing, while Section B B illustrates the staircase from first mid landing to first floor, with accurate rise, tread, and slab thickness details. Reinforcement specifications are clearly indicated, including bar diameters, spacing, and slab thickness around 200 mm, along with beam sizes and landing levels. Plinth level height, mid landing level, and floor level transitions are well defined to support site execution. This staircase structural drawing is suitable for architects, civil engineers, and structural designers working on RCC staircase detailing and construction documentation, supported by foundation and structural layout reference drawings prepared in AutoCAD DWG format for coordinated construction planning.
