A PCBU that commissions construction work on a structure (the client) must, under WHS Regulations Part 6.2, consult the designer so far as reasonably practicable about how to ensure risks arising from the design during construction are eliminated or minimised, and must give the designer any information it holds about the hazards and risks at the site.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
