Compliance Glossary Term

Pre-Qualification

A vetting process where operators assess a subcontractor's safety record, insurance, and certifications before awarding work. Companies must meet minimum standards to be added to an approved vendor list. Failing pre-qualification means being locked out of bidding opportunities entirely.

Related Terms

Leading Indicator

Compliance

A measurable signal that predicts future performance before problems occur. For subcontractors, examples include near-miss reports, toolbox talk attendance, and equipment inspection completion rates. Tracking these helps crews catch safety or productivity issues early.

NCCCO (National Commission for the Certification of Crane Operators)

Compliance

A U.S.-based accreditation body that certifies crane operators through standardised written and practical exams. Many oil and gas and construction clients require NCCCO certification before allowing lift operations on site. Subcontractors must confirm their operators hold valid credentials to avoid mobilisation delays or contract disqualification.

TRIR (Total Recordable Incident Rate)

Compliance

A standardised safety metric that measures workplace injuries per 100 full-time workers annually. Clients use your TRIR to prequalify subcontractors for contracts and site access. A high TRIR can disqualify your crew from working on regulated job sites.

Hot Works

Compliance

Any task that produces open flame, sparks, or heat sufficient to ignite flammable materials. Common examples include welding, cutting, and grinding. Subcontractors typically require a Hot Works permit before starting, and site compliance checks are strict.

Overhead Contact Systems

Compliance

OCS (Overhead Contact Systems) are electrified wire networks suspended above roadways or rail lines to power heavy equipment or vehicles. Subcontractors working near OCS must follow strict clearance protocols to avoid contact hazards. Awareness of OCS boundaries is essential for crane operators, rig movers, and elevated work crews.

LSL (Lead Service Line)

Compliance

A water pipe made from lead that connects a municipal main to a building. Subcontractors must identify and report LSLs during excavation, pipe work, or utility upgrades. Strict handling and disposal regulations apply under federal and provincial environmental codes.
