Accounting reports explain history
The ledger is essential, but it usually records costs after labour is paid or supplier invoices are received. Project control needs an earlier view that includes commitments, work performed but not invoiced, remaining effort and probable commercial recovery.
A forecast should answer what the project is likely to cost and recover at completion—not only what has happened to date.
Start with the accepted baseline
Use the tender or contract budget by meaningful cost code. Preserve labour hours and material quantities as well as dollars so productivity and consumption can be assessed before total cost is known.
Adjust the baseline only through a controlled budget change. Do not erase tender performance by quietly moving overspend between codes.
Include every known commitment
Add issued purchase orders, approved subcontract orders, accrued labour, expected invoices and unavoidable remaining commitments. Review open procurement and uncommitted allowances separately.
The forecast is weak if it assumes the unspent budget is the cost to finish.
Estimate cost to complete from physical reality
Assess remaining quantities, productivity, access, sequence, defects, rework, supervision, programme and procurement. Ask the person responsible for delivery to explain the remaining method and resources.
Forecast labour hours and material quantities first, then convert them to cost. This exposes operational assumptions that a single dollar estimate can hide.
Treat commercial recovery by confidence
Separate approved variations, submitted variations, unpriced changes and disputed value. Use realistic recovery scenarios rather than including every potential variation at full value.
Show both the base forecast and the effect of probable or at-risk recovery so management understands the decision required.
Review actions, not just the percentage
A margin movement should have a reason, owner and corrective action. Review labour performance, procurement variance, variation exposure, claim timing and remaining risk at a consistent cadence.
The goal is not a perfect forecast. It is an early enough forecast to change the result.
Can the project team explain the remaining labour, materials, commitments, risks and recoveries that produce the final margin?
Turn the guidance into a repeatable workflow
SubbieTRAC is designed to keep the tender baseline, project records and commercial actions connected so these controls can happen as part of normal work rather than through another disconnected register.
