(SSHO).

NEI Response: As per specification 01 35 26 section 1.9 B, the SSHO has to be a separate qualified individual from the Prime Contractor’s Superintendent.

Question #14: Given that the two work locations (Martinez VA Medical Center and Mare Island VA Medical Clinic) are approximately 30–40 miles apart, is it acceptable for a single qualified individual to serve as the full-time Site Safety and Health Officer (SSHO) for both sites, provided they can be physically present at each active work area during all construction activities?
