CLA (Combined Licence Application)

A formal document assessing a project's environmental effects before work begins. Subcontractors must align their operations with EIS commitments or risk work stoppages. Scope changes that violate EIS conditions can trigger costly regulatory reviews.

A pipe or cable actively carrying voltage, pressure, or hazardous fluid during work operations. Subcontractors must verify isolation and lockout/tagout status before any work begins. Unauthorised contact can trigger serious liability and stop-work orders.

Occurs 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.

A 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.

The formal process of documenting incidents where no injury or damage occurred, but easily could have. Subcontractors are typically required to report near-misses to the prime contractor or site owner within a set timeframe. Failure to report can result in contract penalties or disqualification from future work.

A government-issued authorisation required before drilling or servicing a well can begin. Subcontractors should confirm a valid permit is in place before mobilising crews or equipment. Work started without one can result in shutdowns, fines, or liability for the operator and service company.
