Institutional Building Connection Corridor and Floor Plan Design

This AutoCAD DWG drawing illustrates a detailed connection corridor design linking the special and lecture building with the library building. The drawing includes roof plan, ground floor, first floor, second floor, and third floor layouts with clearly marked expansion joints and structural alignment. The corridor width is shown as 6250 mm with internal spacing of 3500 mm and side offsets of 1200 mm, ensuring smooth circulation between buildings. Aluminum expansion joint covers, parapet detailing, and urethane waterproof coating layers are clearly indicated in the roof plan. Floor finish legends define exposed concrete smoothing, textured cement mortar, floor tile thickness of 30 mm, and cement mortar waterproof finish with urethane coating for long term durability

The sectional drawing presents vertical coordination from ground level to roof level, connecting spaces such as the chemistry laboratory, music room, art room, lecture rooms, offices, and hallways. Floor-to-floor heights are dimensioned with levels such as GFL, FFL, and roof beam references for construction accuracy. Structural members, beam alignments, slab thicknesses, and corridor junctions are clearly detailed for safe movement and expansion control. Expansion joint positions are consistently marked across all floors to accommodate thermal movement. This AutoCAD DWG file is ideal for architects, civil engineers, interior designers, and builders working on institutional campus projects, offering precise construction guidance through a Cadbull subscription, and can be referenced alongside administrative office block layout plans to understand centralized office planning, circulation hierarchy, and functional zoning within institutional complexes.
