Capacity Charges

The current market rate for materials, fuel, or equipment rentals purchased for immediate delivery. Spot prices fluctuate daily, directly affecting your job cost estimates and margins. Locking in rates early can protect subcontractors from sudden price spikes mid-project.

Expenses already built into a contract rate that cannot be billed separately, such as mobilisation, PPE, or overhead. Subcontractors must identify these upfront to avoid absorbing unrecovered costs. Missing embedded costs during bid review is a common source of margin loss.

The point when project financing is fully secured and contractual obligations become binding. For subcontractors, it typically signals that mobilisation, procurement, and invoicing can officially begin. Work started before financial close carries significant payment risk.

A pricing model where work is billed per unit completed (per meter drilled, per cubic meter hauled, per joint welded, etc.).

A fixed-price contract where the subcontractor delivers a completed scope of work for one agreed total. All cost overruns come out of your margin, not the client's pocket. Scope creep and unforeseen site conditions are your financial risk to manage.

A fixed, all-in rate quoted to a client that requires no further negotiation or adjustments. Subcontractors often offer a cash price to secure faster payment or simplified invoicing. It typically excludes extras like mobilisation, standby time, or material markups.
