Q & A
Q: Where is the definition of a tower crane that states a tower crane is a crane attached to a base?
A: This definition is in OHSR 14.74 Tower Crane Support, which states:
(1) The foundation for support of a tower crane must be certified by a professional engineer.
(2) The design of shoring and bracing to support a tower crane must be certified by a professional engineer, and the shoring and bracing must be constructed as specified by the design.
(3) If a tower crane is supported partially or fully by, or connected to, a building or structure, the connections to and any bracing or shoring of the building or structure necessary to support the tower crane must be certified by a professional engineer.
(5) The loads from a tower crane must be distributed onto its supporting surface to prevent the bearing capacity of the supporting surface being exceeded.
Q: What is a qualified and competent crane supervisor?
A: BC Crane Safety defines a qualified and competent crane supervisor as an individual who has at least 7+ years working knowledge, skill, and experience (recommended). This individual’s skills and role can vary. Qualified and competent crane supervisors may provide direct and indirect supervision.
Qualified means the person has successfully completed exams or training courses or who has extensive knowledge, training and experience and has successfully demonstrated the ability to solve or resolve problems relating to crane assembly, disassembly, operation, and inspection on a worksite.
Competent means the person can also demonstrate knowledge, experience, and skill beyond the successful completion of exams or training courses, including crane assembly, disassembly, operation, and inspection knowledge and demonstrate the ability to identify and correct job/trade related hazards.

Q: What is the reference-checking tool for the Notice of Tower Crane Project?
A: The Notice of Tower Crane Project is an application form to be submitted to relevant authorities before erecting, dismantling, re-positioning, and re-configuring tower cranes. Download the Notice of Tower Crane Project Form from the BC Crane Safety website.
