Staircase Section A A with Water Tank RCC Slab and Level Details

This AutoCAD drawing presents a detailed staircase section A A with an integrated overhead water tank, clearly illustrating vertical circulation and structural coordination. The staircase is designed with a tread of 0.250 m, riser height of 0.175 m, and a clear width of 0.950 m, providing accurate proportions for comfortable movement. Ground-level references are shown at both ends of the section, ensuring proper level coordination. The drawing highlights a total vertical height of 4.05 m with an intermediate level marked at 3.15 m, supporting a clear understanding of floor-to-floor relationships. Each stair flight and landing is properly aligned to reflect real construction conditions.

The section further includes an RCC slab above the lobby and store areas, with a parapet wall height of 1.00 m for roof safety. A water tank is positioned above the staircase zone with a vertical clearance of 2.10 m and a tank depth of 0.90 m, allowing accurate placement during construction planning. The lobby and store spaces are clearly labeled, helping users understand functional zoning in section view. All dimensions, annotations, and levels are precisely indicated, making this drawing useful for architectural detailing, structural reference, and construction documentation in residential or small commercial building projects.
