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.
Discovery Window
Related Terms
Chain-Of-Custody
ComplianceA documented record tracking who handled materials, samples, or equipment at every stage of a job. Subcontractors must maintain this trail to prove proper handling and avoid liability disputes. It is commonly required for soil samples, hazardous materials, and serialised equipment.
Wetland Delineation
ComplianceA regulatory survey that identifies and maps wetland boundaries on or near a project site. Subcontractors must respect these boundaries during ground disturbance, trenching, or equipment staging. Work within delineated areas typically requires additional permits and can trigger project delays.
Crystalline Silica Rule
ComplianceA regulatory standard requiring subcontractors to limit worker exposure to airborne silica dust on worksites. Common in drilling, sandblasting, and concrete cutting operations. Requires action plans, air monitoring, and respirator programmes for affected crews.
Bonded Operator License
ComplianceA 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.
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.
Local Content Requirements
ComplianceRules set by governments or project owners requiring a minimum percentage of local labour, materials, or services on a contract. Subcontractors must demonstrate compliance through hiring records and procurement documentation. Failing to meet thresholds can disqualify your bid or trigger contract penalties.
