Structural Column Schedule AutoCAD DWG with Reinforcement and Tie Spac

This structural column schedule AutoCAD DWG drawing provides complete construction-ready column detailing with sizes, reinforcement, and vertical tie spacing as shown in the drawing. The schedule defines column types C1 with 2 Nos,s C2 with 1 N, os, and C3 with 6 Nos. Below ground level, up to first floor column sizes are 15x19 inch, 18x18 inc,h and 18x18 inch with reinforcement of 4 bars 20mm plus 4 bars 16mm and 10 bars 20mm with a clear cover of 3 inch. Fromthe second floor to the top floor, column sizes change to 12x16 inch, 15x15 inc,h and 15x15 inch with reinforcement of 8 bars 16mm and 4 bars 20mm plus 6 bars 16mm, maintaining a clear cover of 1.5 inch. The column tie spacing detail shows 10mm diameter stirrups at 4 inch center to center in L4 zones at top and bottom portions, and 6 inch center to center in the L2 mid height zone. Material specifications include 72 grade deformed reinforcement bars with fy 72000 psi concrete casting ratio 1:1.5:3, achieving 3500 psi strength,h 19 mm downgraded stone chips, minimum preferred clear cover of 1.5 inch, and mandatory 3 inch clear cover on soil contact sides, ensuring safe structural performance
