Pre-Task Plan

A formal approval process required before altering scope, personnel, equipment, or procedures on a worksite. Subcontractors must submit MOC requests to the operator before making any unplanned changes. Skipping this step can result in work stoppages, liability exposure, or contract penalties.

A documented procedure outlining how a subcontractor responds to on-site incidents, injuries, or hazardous events. It identifies emergency contacts, evacuation routes, and crew responsibilities. Most prime contractors require subcontractors to submit and align their ERP before mobilisation.

The licensed engineer or firm legally responsible for a project's design documents and specifications. Subcontractors must follow their approved drawings exactly — any field changes require written authorisation from the Designer of Record. Deviating without approval can void liability protection and trigger compliance issues.

A construction or industrial site equipped with sensors, cameras, and connected devices to monitor traffic, equipment, and worker movement in real time. Subcontractors operating in these zones must comply with data-sharing and equipment compatibility requirements set by the prime contractor. Non-compliance can result in site access delays or contract penalties.

A designation for companies majority-owned and operated by minorities or women. Many oil and gas and construction prime contractors must meet MWBE subcontracting targets to satisfy government or client diversity requirements. Holding MWBE certification can give field service firms a competitive edge when bidding on regulated projects.

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.
