A formal process for documenting and approving any deviation from original scope, equipment, or procedures on a worksite. Subcontractors must follow the prime contractor's MOC process before making field changes. Skipping this step can void your contract or expose your crew to liability.

Well Licensing
ComplianceA regulatory approval issued by provincial authorities before drilling or completing a well can begin. Subcontractors should confirm a valid licence is in place before mobilising, as work cannot legally proceed without it. Delays in licensing directly affect your crew scheduling and contract start dates.
Ladder Safety System
ComplianceA fixed assembly of rails, brackets, and a climbing sleeve that prevents a worker from falling off a vertical ladder. Subcontractors are often required to install or inspect these systems before crews access elevated structures. Compliance with provincial fall-protection codes is typically a condition of site entry.
Toolbox Talk
ComplianceA short, informal safety meeting held on-site before work begins. Subcontractors are often required to lead or attend these as part of the prime contractor's safety programme. Attendance records may be audited during safety compliance reviews.
Surface Transportation Reauthorization
ComplianceA periodic federal renewal of legislation governing road, rail, and trucking regulations. For subcontractors, it can change load limits, hauling permits, and carrier compliance requirements. Review updates carefully, as new rules may affect equipment mobilisation costs and timelines.
ARO (Asset Retirement Obligations)
ComplianceLegally required costs to decommission and remediate a site at end of life, such as plugging wells or removing infrastructure. Operators budget ARO years in advance, which can create late-project work opportunities for subcontractors. Understand how ARO timelines affect contract scope, since decommissioning work often has strict regulatory deadlines.
OSHRC (Occupational Safety and Health Review Commission)
ComplianceA U.S. federal body that adjudicates disputes when employers contest OSHA citations or penalties. Subcontractors cited for worksite violations can appeal rulings here before escalating to federal courts. Decisions set legal precedents that directly affect safety compliance obligations on job sites.
