OSHA requires 4 anchor bolts at columns per Section 1926.755. This is for stability during construction.
However, if a structural engineer has designed steel columns (not steel posts) to have 2 anchor bolts per column, would/should there be any building inspection issues with having the base plates extended--beyond what the approved drawings detail--to have the OSHA-required 4 bolts (2 bolts in line, on either side of each column)?
I would imagine that a Structural Engineer's Supplemental Instruction form would suffice -- maybe along with an architect's, correct?
For some background information, the plans have been approved/permitted by AHJ. During the second plan review submittal -- when construction bids were coming in -- it was noted by an erector that the above requirement exists. The plans were approved during the 2nd plan review submittal. Hence, my question. I would like to avoid starting off with a revision to the permitted drawings.
(Interestingly, the regulation doesn't specify if the required four anchor bolts can be in-line or spaced evenly around the column.)
