Residential Foundation AutoCAD Plan 2nd Basement with Lift Pit

This AutoCAD DWG drawing shows a detailed residential structural foundation plan prepared for a second basement level at approximately level minus 5.77 m. The plan includes a complete layout of footing blocks, columns, grade beams, and slab framing with grid references and axis markings. Foundation block sizes, column positions, and beam connections are clearly labeled to support accurate structural execution. The drawing also illustrates load transfer zones and alignment between basement structural elements and the superstructure above, ensuring coordinated construction planning.

Additional details include a dedicated elevator pit foundation shown at approximately level minus 7.27 m with exact pit dimensions, footing layout, and reinforcement positioning. Typical footing block details, section cuts, and schematic views are provided for clarity. Structural notes reference design criteria, material specifications, and construction tolerances as per standard codes. The layout also includes durability criteria, concrete grades, and reinforcement guidelines for basement conditions. This foundation AutoCAD DWG file is ideal for structural engineers, civil engineers, and builders working on residential buildings with multi-level basements and lift core requirements.
