26. RFI #26 Question: Ref spec 01 45 00 part 1.4…. For fair bidding practices and for GCs currently not onsite conducting projects, does the full-time onsite QC manager need to be dedicated to the bld. 22 project?

Answer: Per 01 35 26 Safety Requirements, Part 1.7.C, the Site Superintendent, SSHO, and QC Manager can be the same individual if all training requirements are met per other parts of the specifications. The GC's higher level QC manager does NOT need to be dedicated to this project alone.

27. RFI #27 Question: The site Superintendent may serve as the on-site Safety manager.

This is in part why the VA requires the Site Superintendent to have the OSHA 30 hour certification. The GC's higher level Safety Manager does not need to be dedicated to this project alone.
