Bonding Capacity
ComplianceThe maximum value of surety bonds a subcontractor can obtain, proving financial reliability to general contractors and project owners. Higher bonding capacity allows you to bid on larger or multiple simultaneous contracts. Insurers set this limit based on your financials, credit history, and past project performance.
NRC (Nuclear Regulatory Commission)
ComplianceA U.S. federal agency that regulates civilian nuclear facilities and materials. Subcontractors working near nuclear sites must meet strict NRC access and safety requirements. Non-compliance can result in immediate removal from site.
Federal Lease
ComplianceA government-issued agreement granting a company the right to explore or extract resources on federally managed land. Subcontractors working on these sites must meet stricter regulatory and documentation requirements. Expect additional compliance checks, environmental controls, and reporting obligations on federally leased projects.
Caught-In Hazard
ComplianceA workplace danger where a worker's body or clothing becomes trapped, pinched, or pulled into moving machinery, equipment, or materials — common on oilfield and construction sites where subcontractor crews work near rotating equipment, conveyor systems, or heavy moving loads. Subcontractors are responsible for identifying and controlling these hazards through proper guarding, lockout/tagout procedures, and site-specific hazard assessments before work begins.
Heat Illness Prevention Program
ComplianceA documented safety plan requiring subcontractors to manage worker exposure to extreme heat on jobsites. It typically covers hydration protocols, work-rest cycles, and heat acclimatisation schedules. Clients and prime contractors often require proof of a compliant program before mobilisation.
Approved Vendor List
ComplianceA client- or prime contractor-maintained registry of pre-qualified suppliers and subcontractors eligible to bid on work. Getting onto an AVL often requires submitting safety records, insurance, and certifications in advance. Without AVL status, subcontractors are typically blocked from receiving purchase orders or contracts.
