Staircase and Elevator Core Drawing with Floor Plans and Section

This AutoCAD DWG drawing illustrates a complete staircase and elevator core layout designed for an institutional building. The drawing set includes ground floor, first floor, and second floor plans showing stair positioning, elevator shaft alignment, corridor connections, and room access points. The stair core is centrally planned with clear circulation widths, landings, and turning spaces suitable for continuous vertical movement. Section AA provides a detailed vertical cut through the stair and lift area, explaining floor-to-floor height, stair slope, riser and tread proportions, slab thickness, beam positioning, and roof profile. Elevator shaft dimensions, pit depth, overhead clearance, and door alignment are clearly marked for coordination. Corridor widths, wall thicknesses, structural columns, and floor level references are accurately dimensioned to support execution and coordination. The drawing also highlights handrail placement, stair landing transitions, and connections with external corridors at each level. This staircase and elevator drawing is ideal for architects, civil engineers, and builders working on multi-storey education or public buildings. It supports precise planning, structural detailing, and multidisciplinary coordination across AutoCAD, Revit, SketchUp, and 3D workflows, making it suitable for construction documentation and approval drawings. It can be effectively coordinated with foundation and footing CAD drawings that define load transfer, column support, and structural base detailing for safe and accurate execution.
