Staircase Case Detail Drawing with Ground First Second Floor Plans

This AutoCAD DWG drawing presents a detailed staircase case layout prepared for an institutional building with clear circulation and structural clarity. The drawing includes ground floor, first floor, and second floor plans showing stair position, stair width, landing size, wall thickness, column layout, and corridor connections. Each floor plan illustrates consistent stair geometry with defined riser height, tread depth, and landing proportions for safe movement. Section AA and Section BB explain vertical circulation from foundation to roof level with clear floor-to-floor heights, slab thickness, beam depth, and roof slope detail. Reinforced concrete stair flights, intermediate landings, and structural supports are clearly indicated for construction accuracy. Handrail height,t edge protection, and stair enclosure walls are detailed to support safety compliance. Floor level markings, finished floor levels, and material notes assist coordination during execution. The drawing also highlights roof framing, ceiling height, and stair headroom clearance. Dimension strings and grid references ensure precise site setting out. This staircase case drawing is suitable for architects, civil engineers, and builders working on education or public building projects, and is closely related to straight staircase CAD drawings that include 3D AutoCAD design views for better understanding of stair geometry, vertical circulation, and execution-level detailing.
