API 579 (Fitness-For-Service) is an industry standard used to assess whether ageing or damaged equipment is safe to keep operating. Subcontractors may be required to support or comply with these assessments during inspection and maintenance scopes. Understanding it helps when working alongside integrity engineers on pressure vessels, piping, and tanks.

Related Terms
Underground Utility Strike
ComplianceAn accidental hit to a buried line — gas, electric, telecom, or water — during excavation or drilling. Subcontractors are typically liable for damages, work stoppages, and injuries if proper locates weren't completed. Always confirm valid BC One Call or Alberta One-Call tickets before breaking ground.
OEB (Ontario Energy Board)
ComplianceOntario's regulatory body overseeing electricity and natural gas utilities. Subcontractors working on regulated energy infrastructure in Ontario must align with OEB-approved project scopes and rate structures. Non-compliance can affect contract eligibility with major utilities.
Compliance Theater
ComplianceWhen a prime contractor or owner requires paperwork and box-checking that looks rigorous but adds no real safety value. Subcontractors absorb the administrative burden without reducing on-site risk. Recognising it helps crews push back on inefficiencies that drain time and resources.
DOE (Department of Energy)
ComplianceA U.S. federal agency that regulates energy production, sets safety standards, and oversees projects involving nuclear, fossil fuel, and renewable energy. Subcontractors working on DOE-funded or DOE-regulated sites must meet strict compliance and security requirements. Contracts tied to DOE projects often include additional reporting obligations and certified personnel requirements.
CBP (Customs and Border Protection)
ComplianceThe U.S. federal agency that regulates the entry of workers, equipment, and materials across the Canadian-American border, which subcontractors must navigate when mobilising crews or hauling specialised equipment into U.S. job sites. Non-compliance with CBP requirements can result in delays at the border, seized equipment, or crews being turned away, making proper documentation and advance planning critical for cross-border field work.
Classification (aggregate)
ComplianceA method of grouping all subcontractor invoices or costs together to assess total contract value or spending thresholds. Owners and primes use aggregate classification to trigger compliance requirements, audit rights, or tiered pricing terms. Subcontractors should track cumulative billing carefully, as crossing thresholds can change contract obligations.
