This Basement 1 structural AutoCAD drawing is prepared for GA2 Tower B1, a high-rise commercial office building that requires a detailed reinforced concrete layout for accurate construction planning. The drawing includes a complete structural grid, column placements, core zones, ramp alignment, and basement circulation essential for a large commercial tower. Concrete specifications are clearly noted, including column grade fc 45 N per mm2 and beam and slab grade fc 40 N per mm2 with BJTS 420B reinforcement steel. The plan also highlights mid-rise and tower core locations, parking distribution, lift wells, wall alignments, and all measurements in millimetres and coordinates in meters. The foundation and column spacing are displayed through precise markings, sectional references, and footing centers. Consultant details from structural, architectural, and MEP teams are included along with revision notes and engineering approvals. This structural basement plan ensures proper understanding of load paths, reinforcement requirements, and construction sequencing for a high-rise office tower.

This AutoCAD DWG file is ideal for architects, civil engineers, interior designers, builders, and users of AutoCAD, Revit, SketchUp, and 3d Max who need an accurate structural basement layout for commercial tower projects. With its detailed grid system, concrete grades, reinforcement reference, and core planning, this drawing supports professional coordination and site execution.
