One might expect that the construction standards promulgated by the applicable occupational safety and health agency (i.e., federal or state) would specify site safety roles, but this is far from the case. Nearly all construction projects not located in states that have their own OSHA are governed primarily by Title 29, Part 1926, Subparts C–Z of the Code of Federal Regulations (29 CFR 1926). All construction activities are also governed by general industry safety requirements (Part 1910) insofar as they are not superseded by Part 1926 (Toole and Gambatese 2002). In addition, federally funded construction projects are also governed by Subparts A and B of 29 CFR 1926 (California and Michigan have OSHA standards that substantially differ from those promulgated by the federal government’s Department of Labor; other states have standards that represent only minor deviations from the federal OSHA standards).
