Worker Misclassification
ComplianceOccurs when a subcontractor or field worker is incorrectly classified as an independent contractor instead of an employee. This exposes hiring companies to back-taxes, penalties, and liability for unpaid benefits. CRA audits in oil and gas and construction regularly target this issue.
Hazard Orientation
ComplianceA mandatory site-specific safety briefing required before subcontractor crews begin work on a new location. It covers site-specific risks, emergency procedures, and restricted zones. Primes or operators typically deliver it, and subcontractors must document attendance for compliance.
Bonding Capacity
ComplianceThe maximum value of surety bonds a subcontractor can obtain, proving financial reliability to general contractors and project owners. Higher bonding capacity allows you to bid on larger or multiple simultaneous contracts. Insurers set this limit based on your financials, credit history, and past project performance.
CCO (Certified Crane Operator)
ComplianceA crane operator who holds recognised certification confirming competency to safely operate lifting equipment on job sites. Most oil & gas and construction contracts require subcontractors to supply CCO-certified operators. Verify certification currency before mobilisation, as expired credentials can halt work and trigger compliance penalties.
Roof Control Plan
ComplianceA site-specific document outlining how ground or overhead hazards will be managed in underground or enclosed work areas. Subcontractors must review and follow it before starting work on a mine or tunnel site. It defines approved support methods, inspection requirements, and who holds authority to halt unsafe work.
Energize
ComplianceTo bring electrical equipment or a system into a live, powered state on a job site. Subcontractors must confirm proper authorisation and lockout/tagout clearance before energizing any equipment. Premature energizing is a leading cause of worksite incidents and contractor liability.
