| 03128 Dimensions and Tolerances
Except where specially noted, dimensions, tolerances, sizes, positions, and concrete cover to reinforcement shall be as dimensioned in the drawings with the following tolerances: -
Tolerance for the dimensions of concrete section (total depths of a beam or lab, breadth of a beam or web thickness, dimensions of column section):
Delta 1 = 0.051 for 1 400mm
Delta 1 = 20 mm for 1 400mm
Tolerances for effective depths:
Delta 1 = 0.751 for 1 200mm
Delta 1 = 0.51 + 5mm for 200 1 400mm
Delta 1 = 25mm for 1
Tolerance on minimum concrete cover:
Delta 1 = 5mm
Deviation of the dimension of a section from those indicated in drawings shall not exceed the lesser of 2% 50mm greater accuracy than 10mm is however, not required.
Permanent horizontal size curvature of a member shall be less than 0.2% of the span.
Levels of floor slabs, beams lintels, etc. intended to be horizontal must not slope more than 6 mm in 3 meters.
Errors in plumbing to be not more than plus or minus 6mm and no line intended to be straight and vertical shall slope more than 6mm in 3 meters.
