Quantum & Cost Claims

Precise quantification of your financial entitlements

We prepare evidence-based quantum submissions that clearly substantiate every element of your financial claim — from prolongation costs and loss of productivity to acceleration expenses and variation valuation.

Our quantum services

Prolongation costs

We calculate the time-related costs incurred during the extended contract period, including site overheads, staff costs, equipment standing charges, and head office overheads. We apply recognized formulae (Hudson's, Emden's, Eichleay) as appropriate.

Disruption claims

When events reduce your productivity without necessarily causing critical delay, you may be entitled to disruption damages. We use measured mile analysis, earned value comparisons, and industry studies to quantify the loss of productivity.

Acceleration costs

Whether directed or constructive acceleration, we substantiate the additional costs of measures taken to recover programme delays — overtime, additional resources, shift working, and expedited procurement.

Variation valuation

We assess and value contract variations using bill of quantities rates, analogous rates, and first principles cost build-ups. We ensure every variation is properly measured, valued, and documented.

FAQ

Common questions about quantum claims

What is the difference between prolongation and disruption?
Prolongation relates to time-dependent costs incurred because the project took longer than planned. Disruption relates to reduced productivity — the contractor needed more resources or time to perform the same scope of work due to employer-caused events.
How do you calculate head office overheads?
We apply recognized formulae including Hudson's, Emden's, and Eichleay, selecting the most appropriate based on the circumstances and jurisdiction. We also consider actual cost-based approaches where sufficient records exist.
What records do you need for a quantum claim?
Key records include cost reports, payroll records, equipment logs, procurement records, invoices, the bill of quantities, variation orders, and correspondence regarding additional costs. The more detailed your records, the stronger the claim.
