Daily oil & gas and construction news for subcontractors

ComplianceGlossary Term

Fitness-For-Service (ffs)

A formal engineering assessment that determines whether aging or damaged equipment is safe to keep operating. Subcontractors may be required to conduct or document FFS evaluations before resuming work on pressure vessels, pipelines, or structural components. Results directly affect your scope of work, liability exposure, and project timelines.

Related Terms

Exposing Employer

Compliance

The company that directly exposes workers to a hazard on a multi-employer worksite, such as a subcontractor whose crew creates a fall risk. Under Canadian OHS regulations, the exposing employer holds primary responsibility for controlling that hazard. Subcontractors must understand this designation, as it determines who is liable for corrective action.

Pre-Qualification

Compliance

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.

Tunnel Ventilation

Compliance

A system that controls airflow in enclosed underground worksites to remove hazardous gases, dust, and fumes. Subcontractors must verify ventilation meets regulatory standards before crews enter. Inadequate ventilation can trigger work stoppages and liability for prime contractors.

Reclamation

Compliance

The process of restoring a work site to its original or agreed-upon condition after project completion. Subcontractors are often scoped for reclamation work including grading, revegetation, and soil remediation. Reclamation scopes are regulated and must meet provincial closure criteria before sign-off.

Soil Classification

Compliance

A system for categorising ground conditions by type, stability, and load-bearing capacity. Subcontractors use it to determine excavation methods, shoring requirements, and equipment suitability. Misreading soil class can trigger safety violations or costly project delays.

Worksite Enforcement

Compliance

The active monitoring and enforcement of safety, regulatory, and contractual rules on a job site. For subcontractors, non-compliance can result in stop-work orders, fines, or contract termination. Prime contractors typically hold enforcement authority over all subs on site.
