Estimating Backlog

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 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.

A temporary halt to production or operations at a well or facility, which often results in subcontractors being stood down with little notice, directly impacting billable hours and crew scheduling. Understanding shut-in clauses in your service agreement is critical, as they typically limit or eliminate your ability to claim standby pay or mobilisation costs during the downtime.

A pricing model where contractors are paid a fixed daily rate for equipment and/or personnel, regardless of the amount of work completed that day.

A formal document issued by prime contractors or operators asking subcontractors to submit detailed pricing and specifications for specific field services, equipment, or labour. RFQs typically include project scope, timelines, and technical requirements that subcontractors must address to compete for the contract.

A disconnect between what a subcontractor quoted and what the client expects to pay for. This often surfaces during invoicing when scope, rates, or billing terms were not clearly agreed upon upfront. It can delay payments and strain relationships with prime contractors.
