What is “moderate reaming” as indicated in the 2005 AISC Code of Standard Practice Section 7.14?
During the course of erection, it occasionally becomes necessary to ream holes so fasteners can be installed without damage to the threads, resulting in a hole that is larger than normal or elongated. The hole types recognized by the AISC and RCSC Specifications are standard, oversized, short-slotted, and long-slotted, with nominal dimensions as given in the 2005 AISC Specification Table J3.3. From the 2005 AISC Code of Standard Practice Section 7.14 Commentary, “the term “moderate” refers to the amount of reaming, grinding, welding or cutting that must be done on the project as a whole, not the amount that is required at an individual location. It is not intended to address limitations on the amount of material that is removed by reaming at an individual bolt hole, for example, which is limited by the bolt-hole size and tolerance requirements in the AISC and RCSC Specifications.” Note that reamed holes must meet the provisions for minimum spacing and minimum edge distance in the 2005
