NSSGA (National Stone, Sand & Gravel Association)

An official work request issued before any ground disturbance, requiring underground utilities to be marked out. Subcontractors must have an active locate ticket on site before excavation begins. Working without one can result in fines, liability, or contract termination.

A licence that requires the holder to carry a surety bond as financial assurance that they will meet regulatory obligations, meaning subcontractors and field service companies must maintain this bond coverage to legally operate certain equipment or perform specific scopes of work on a client's site. For subcontractors, holding a bonded operator licence is often a prerequisite for bidding on contracts, as it signals to operators and general contractors that financial accountability is in place if work standards or regulatory requirements are not met.

Texas state agency that regulates electric, telecom, and water utilities. Subcontractors working on utility infrastructure projects in Texas must align with PUCT-governed standards and permitting. Non-compliance can delay project approvals and payment milestones.

A documented response to a safety incident, audit finding, or client complaint that outlines steps taken to fix the root cause. Subcontractors are often required to submit corrective action reports to maintain contract standing. Failure to close them out on time can result in suspension from a client's approved vendor list.

A deliberate breach of a safety regulation or worksite rule, where the subcontractor knew the requirement and chose to ignore it. Regulators treat these far more severely than accidental non-compliance. Fines, stop-work orders, or contract termination can follow.

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.
