RE: Column Anchor Bolt Placement

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Isn't it the responsibility of the contractor to comply with OSHA and all 
other construction safety requirements, not the SEOR's responsibility?

With this OSHA requirement, it seems that the distinction between contractor 
and SEOR responsibility is getting foggy.  SEOR designs and specifies a 
minimum of 4 A.B.'s based on structural analysis.  At what point does 
contractor revise A.B. size/number/embedment to comply with OSHA?
