Daily oil & gas and construction news for subcontractors

ComplianceGlossary Term

Discovery Window

The 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.

Related Terms

Excavation Guarding

Compliance

Physical barriers, signage, and safety controls required around open excavations to prevent falls and unauthorised access. Subcontractors are responsible for installing and maintaining guarding on their worksites. Failure to comply can result in stop-work orders, fines, or liability for incidents.

OFAC (Office of Foreign Assets Control)

Compliance

A U.S. Treasury agency that enforces sanctions against designated countries, companies, and individuals. Subcontractors must screen clients and vendors against OFAC lists before accepting contracts or payments. Working with a sanctioned party can result in severe fines and contract termination.

Federal Onshore Acreage

Compliance

Land managed by the federal government and leased for oil, gas, or resource extraction. Work on these lands requires additional permits, compliance steps, and federal oversight. Subcontractors must verify their employer holds valid federal authorisations before mobilising.

FERC (Federal Energy Regulatory Commission)

Compliance

The U.S. federal body that regulates interstate energy infrastructure, including pipelines and transmission lines. Projects requiring FERC approval often have strict compliance timelines that affect subcontractor scheduling and scope. Work on FERC-regulated assets may require additional permitting and documentation.

MSHA (Mine Safety and Health Administration)

Compliance

A U.S. federal agency that regulates safety at mines and quarries. Subcontractors working on mine sites must comply with MSHA standards, separate from OSHA rules. Workers may require site-specific MSHA training before mobilising.

Venting

Compliance

The controlled release of gases from pipelines, vessels, or equipment during maintenance, commissioning, or decommissioning work. Subcontractors must follow site-specific venting procedures to remain compliant with environmental and safety regulations. Improper venting can result in work stoppages, fines, or removal from site.
