  • General

In accordance with the Legislative Provision, notably the Occupational Safety and Health (OSH) Act 1984, Section 23 and OSH Regulations and Guidance, we advise that as far as reasonably practicable, we have adopted safe design practices in identifying unusual hazards and either eliminating or minimizing the attendant risks to building users. Any residual hazards are listed in the risk management schedule. The contractor is to take responsibility for the risks as stated and price the appropriate works to eliminate or limit the risk during construction. The contractor is to integrate outstanding risks into the appropriate Operating and Maintenance manuals and make aware the appropriate safe working procedure.
