Step Footing Foundation CAD DWG with DPC and RCC Wall Details

This AutoCAD DWG file provides a detailed step-by-step footing foundation design for residential and commercial structures. It includes precise foundation dimensions for 4½" and 9" thick walls, showing the depth of footing, width at base, and gradual step formation. The drawing illustrates reinforced cement concrete (RCC) wall sections with detailed measurements, including floor level (F.F.L), plinth level (P.L), roof level (R.L), and natural soil level (N.S.L). Damp-proof course (DPC) detailing is also included to prevent moisture infiltration and ensure durability. Each wall thickness is carefully dimensioned to ensure structural stability and alignment with architectural standards.
