The BC prime contractor: verify designation and actual coordination
A brewery owner hires electrical, mechanical and millwork contractors directly. Everyone assumes the largest contractor is the prime contractor, but the startup file contains no written agreement identifying that role.

Find the actual designation before relying on an assumption. BC’s Act defines the prime contractor through a written agreement with the owner; without one, the owner is the prime contractor. WorkSafeBC’s overview distinguishes overall coordination from each employer’s responsibilities. The largest package, a general-contractor label or a shared contact sheet does not settle the role. Identify the actual workplace and agreements, then check its required coordination arrangements.
Give the legal role a received site arrangement
- Verify the workplace and written agreement. List the employers working at the actual site and compare the startup records with the current Act’s definitions. Locate the signed prime-contractor agreement, if there is one, and clarify its applicable workplace and parties. Refer an absent, unclear or conflicting designation through the appropriate owner and advisory route. Do not quietly fill the gap with the person who chairs the production meeting.
- Separate designation from coordination delivery. WorkSafeBC describes the prime contractor’s coordination and compliance-system responsibilities while employers retain their own duties. Ask how the actual site communicates hazards, receives employer contacts and resolves overlapping work. Record the working arrangements and their owners. A designation establishes a role; it does not demonstrate that information reached a trade or that a newly conflicting task has been reviewed and controlled.
- Check the construction-specific coordinator provision. Read section 20.3 against the actual overlapping or adjoining activities, hazard and combined-workforce conditions. It includes qualified-coordinator and current site-information requirements when those conditions apply. Keep that check separate from the Act’s prime-contractor definition: the conditions for this construction provision do not mean smaller multi-employer workplaces have no coordination duties. Record the actual determination and ask the regulator when application remains unclear.
- Maintain the arrangements when contractors change. Update the responsible contacts, receiving briefings and shared information when another employer or activity arrives. Check who receives advance information about work affecting others and how the response reaches the relevant supervisors. Keep unresolved interfaces visibly pending. A current name on the wall is useful, but the coordination record also needs to show what changed and how the affected work was addressed.
Common mistakes
- Assuming the largest contractor automatically holds the role.
- Confusing a contact list with a written designation.
- Applying one provision’s conditions to every coordination duty.
- Leaving shared arrangements unchanged when a new trade arrives.
Checklist
Check designation and delivery separately
- Actual workplace, employers and written agreement.
- Role clarified through the proper route.
- Received coordination and employer contacts.
- Applicable section 20.3 determination.
- Updated shared information and changed-work responses.
Check your understanding
The site has fewer workers than a particular construction provision describes. Does that remove the prime-contractor role?
