Multi Storey Building Vertical Circulation and Core Planning Drawing

This drawing presents a detailed core wall key plan with staircase layout and sectional views. The image includes lift shaft positioning, stair flight arrangement, landing dimensions, and wall thickness markings. All plans and sections are clearly labeled with reference grids, center lines, and level indicators. The staircase detail shows step height, tread width, railing alignment, and structural support layout. Each drawing view is properly scaled and drafted to represent vertical circulation and core planning within a building structure.

The sectional drawings illustrate shaft walls, lift cabins, stair enclosures, slab connections, and floor-to-floor height details. Frame lines, fixing points, and construction joints are accurately marked for technical coordination. The image focuses on core area planning, stair circulation, and vertical movement design. All components are arranged to support architectural layout preparation, structural coordination, and construction documentation. This drawing provides clear visual guidance for integrating staircase and lift cores into multi-storey building designs.
