Stair Detail Drawing with Riser Tread Section and Level Heights

This Stair Detail Drawing is prepared in AutoCAD DWG format and provides a clear sectional representation of a multi-storey staircase system. The drawing illustrates continuous stair flights connecting multiple floor levels with accurate riser and tread configuration. Standard riser height of approximately 150 mm to 170 mm and tread width of about 270 mm to 300 mm are clearly indicated for safe movement and code-compliant design. Floor-to-floor heights, landing levels, slab thickness, and beam connections are shown in the section for proper structural coordination. Handrail alignment, stair slope, and landing projections are also defined with reference dimensions.
