Environmental Impact Statement (eis)

A measure of greenhouse gas emissions produced per unit of work or energy output. Operators increasingly require subcontractors to report and reduce carbon intensity on job sites. Lower scores can be a competitive advantage when bidding on contracts.

A series of repeated safety or regulatory infractions flagged by inspectors or clients over time. For subcontractors, it signals systemic non-compliance and can trigger contract termination or disqualification from future bids. Regulators may impose escalating fines or mandatory audits based on documented patterns.

The U.S. Department of Labour branch that enforces federal wage laws, including overtime and minimum wage rules. Subcontractors must ensure field crew pay practices meet WHD standards to avoid audits and penalties. Misclassifying workers as independent contractors is a common trigger for WHD investigations.

Subcontractors are often required to perform or witness EVIs before mobilising equipment on site. Results are typically recorded on inspection forms tied to client or regulatory compliance packages.

A U.S. federal environmental assessment required before major project approvals on public lands. Subcontractors may face work delays or scope changes while reviews are completed. Mobilisation schedules should account for potential NEPA-related hold periods.

A permanently mounted ladder attached to a structure, vessel, or facility used to access elevated work areas. Subcontractors must ensure fixed ladders on their worksites meet provincial and federal safety standards before crews use them.
