Diesel Surcharge

A standing approval that allows subcontractors to perform recurring work up to a set dollar limit without requiring a new work order each time. It simplifies billing and reduces administrative delays on long-term contracts. Subcontractors should confirm spending thresholds in writing before mobilising crews.

Financing borrowed against a specific project's revenue, not the owner's overall assets. Subcontractors should know this because payment depends on that project performing financially. If the project underperforms, your invoices may be delayed or disputed.

A property lease where the tenant pays rent plus property taxes, insurance, and maintenance costs. Subcontractors leasing yard space, shops, or staging areas often encounter this structure. Budget carefully — these added costs can significantly impact project overhead.

The gradual increase or decrease in actual field quantities compared to original contract estimates. For subcontractors, untracked drift leads to unbilled work or disputed invoices at project close-out. Monitor quantities continuously to support change order claims.

An accounting category tracking costs for projects not yet complete or placed into service. For subcontractors, your invoiced work may sit in a client's CWIP account until project completion. This can affect payment timing and how clients prioritise approving your billings.

A buffer of extra labour, equipment, or budget set aside to cover unexpected delays or scope changes on a project. Subcontractors use it to avoid cost overruns when field conditions shift. Typically expressed as a percentage of the total estimated project value.
