Dust Suppression
ComplianceThe process of controlling airborne particulates on worksites using water trucks, chemical agents, or barriers. Subcontractors may be contractually responsible for dust suppression on access roads, laydown yards, or excavation sites. Failure to comply can result in stop-work orders or back-charges from the prime contractor.
Environmental Permitting
ComplianceThe process of obtaining government approvals before starting work that may impact land, water, or air. Subcontractors must confirm permits are in place before mobilising — delays can halt work without pay. Missing or expired permits can expose your company to fines and contract termination.
MI (Mechanical Integrity)
ComplianceA regulatory and operational standard confirming that pressure-containing equipment is fit for service and free from defects. Subcontractors working on vessels, pipelines, or wellheads must often meet MI requirements before commencing work. Non-compliance can halt operations and trigger liability for field service crews.
Discovery Window
ComplianceThe limited timeframe in which a subcontractor can identify and formally report hidden site conditions that differ from the original contract scope. Missing this window typically voids your right to claim additional compensation or schedule relief. Review your contract carefully — discovery windows can be as short as 24 to 72 hours after encountering the condition.
CEM (Continuous Emissions Monitoring)
ComplianceAutomated systems that track pollutant outputs from equipment in real time. Subcontractors operating combustion equipment may be required to install, maintain, or provide data from these systems. Non-compliance can trigger work stoppages or contract penalties.
FAR (Federal Acquisition Regulation)
ComplianceThe FAR governs purchasing rules for U.S. federal contracts, including subcontractor requirements on government-funded projects. If your prime contractor holds a federal contract, FAR clauses flow down and bind your work. These rules cover pricing, record-keeping, audits, and labour standards you must follow.
