Stair Detail Drawing with Beam Layout and Structural Dimensions

This Stair Detail Drawing is prepared in AutoCAD DWG format and provides complete structural planning for staircase construction with beam and slab coordination. The drawing includes the layout of first-floor beams, roof beams, and reinforced concrete slab details connected to the stair core. Beam sizes, spacing, and alignment are clearly shown with grid references and center lines for accurate execution. Staircase location is coordinated with surrounding structural members, ensuring proper load transfer and stability. Typical beam widths range from 230 mm to 300 mm, with slab thickness generally indicated around 120 mm to 150 mm for standard construction requirements. Riser and landing connections are clearly integrated within the structural framework.
