Checks

3 to look at
  • 1. Value and cost entered for this monthOK
  • 2. Accruals carried from an earlier monthLook at this

    1 old accrual(s) carried 2+ months: chase or release.

    Why it matters: An accrual left in for another month may already be on the ledger (counted twice) or may never be invoiced. Old ones are the riskiest.

    What to do: Confirm each one is still owed, with a reason, or release it.

  • 3. Recognition overridden without a reasonOK
  • 4. Cost to complete is just budget less cost to dateLook at this

    Sub-subcontract.

    Why it matters: That isn't a forecast: it assumes the rest of the job goes exactly to budget, which hides overruns until the end.

    What to do: Rebuild cost to complete from the work left to do.

  • 5. Negative cost to completeOK
  • 6. Big margin move, or well above tenderLook at this

    Forecast margin moved -9.17 pp.

    Why it matters: Boards distrust a margin that jumps, or one far better than the tender, unless the reason is written down.

    What to do: Explain the move in the reasons box before the meeting.

  • 7. Main contractor valuing below our application, three months runningOK
