Designer of Record

A regulatory survey that identifies and maps wetland boundaries on or near a project site. Subcontractors must respect these boundaries during ground disturbance, trenching, or equipment staging. Work within delineated areas typically requires additional permits and can trigger project delays.

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.

A technique where certified technicians use ropes and harnesses to reach elevated or confined work areas without scaffolding. Common in tank inspections, flare stack maintenance, and structural repairs. Subcontractors must ensure crews hold valid IRATA or SPRAT certifications before mobilising.

The process of locating and marking buried utilities before any ground-breaking work begins. Subcontractors are legally required to call before you dig under provincial one-call regulations. Failure to comply can result in fines, project shutdowns, and liability for repair costs.

Documentation that can withstand scrutiny from a client, regulator, or auditor without requiring additional explanation. For subcontractors, this means timesheets, invoices, and safety records are complete, dated, and traceable. Gaps or inconsistencies in paperwork can trigger payment disputes or compliance penalties.

The length of time a work permit remains valid before requiring renewal or reissuance. Short permit durability can stall field crews and create costly downtime between tasks. Subcontractors should confirm permit expiry windows before scheduling labour and equipment.
