This DWG file presents detailed stair layout plans with step dimensions, riser heights, tread depth, landing details, handrail positioning, and structural connections. It also includes sectional views and elevation profiles that illustrate how stairs integrate with floor slabs, walls, and support beams for safe vertical circulation. Ideal for architects, civil engineers, interior designers, and builders, the drawing provides precise measurements and annotations required to ensure correct stair construction and building compliance.
