NPT (Non-Productive Time) is any period when crews or equipment are on-site but not performing billable work. This includes weather delays, equipment breakdowns, or waiting on materials. Subcontractors often absorb NPT costs unless contracts clearly define standby rates.
Non-Productive Time
Related Terms
Levelized Cost
Cash FlowThe average total cost of delivering a service or operating equipment, spread evenly across its full working life. Subcontractors use it to set competitive day rates that recover mobilisation, maintenance, and labour costs over time. It helps avoid underpricing long-term contracts where early margins look healthy but tail-end costs erode profit.
Escalation Clause
Cash FlowA contract provision that allows your rates or pricing to increase if specific costs rise, such as fuel, labour, or materials. It protects subcontractors from absorbing unexpected cost spikes during long-term projects. Always verify trigger conditions and notice requirements before signing.
Priced Option
Cash FlowA pre-negotiated scope item included in a contract at a fixed rate, which the client may activate later without rebidding. Common in turnarounds and construction projects for add-on scopes like additional inspection work or extra crews. Securing favourable rates upfront protects subcontractors from rushed low-ball pricing pressure mid-project.
Master Default Order
Cash FlowA court order declaring a prime contractor in default on financial obligations, often freezing payments to subcontractors. It signals serious insolvency risk and can delay or eliminate outstanding invoices. Subcontractors should file liens immediately upon receiving notice.
Unit Rate
Cash FlowA pricing model where work is billed per unit completed (per meter drilled, per cubic meter hauled, per joint welded, etc.).
Capital Budget
Cash FlowA client's approved spending plan for major projects, equipment, and infrastructure in a given year. When capital budgets are set or revised, subcontractors see direct impacts on contract awards and work volumes. Monitoring clients' capital budget cycles helps you time bids and resource planning effectively.
