Maximum Tolerances
Maximum tolerances are presented in tables organized by the particular type of work involved: which includes core drilling; diamond cutting of ceilings and walls; diamond cutting of floors, with one set of tolerances for rail-mounted equipment and a slightly different set for wheel-driven saws; wire sawing, in both horizontal and vertical structures.
Depending on their applicability, different measurements are addressed for those sawing and drilling activities. For example, core drilling and diamond cutting include tolerances for alignment accuracy and for hitting the target depth, whereas wire sawing do not. All include tolerances for some form of directional accuracy, for vertical and horizontal levelness, and for surface roughing.
Finally, a tolerance is given for hole diameter deviations in core drilling, and width of cut deviations for wire sawing and diamond cutting.
