Writing the variance narrative: amount, cause, recovery and next month's effect
Beside the formwork code, the monthly explanation reads over budget again. The office can see that from the figures already. It still cannot tell what happened, whether the cost is carried in the forecast or who is pursuing a proposed recovery.
Write the variance in four parts: its amount and comparison basis, the cause, the recovery position and the effect on the next forecast. Use a factual event that explains the movement rather than repeating the code's label. Keep the cost forecast separate from uncertain recovery. The reader should be able to follow the amount back to records and understand which decision remains open.
Replace the label with an explanation
- Name what is being compared. State whether the amount is against budget, last month's forecast or another agreed baseline. Give the direction in words as well as a sign. A positive dollar entry can mean a worsening cost forecast in one report and a saving in another.
- Identify the event and cause. Describe the work, location and observed reason. Distinguish a confirmed layout error from a suspicion about responsibility. If the cause is still being checked, say what evidence is missing and who will obtain it.
- Explain the amount's composition. Link the total to its main labour, material, equipment or remaining-work elements. State whether it is recorded cost, a revised estimate or both. Keep ticket and forecast references available without filling the short narrative with every transaction.
- State the recovery position precisely. Separate proposed, submitted, disputed and agreed recovery using the commercial record. Name the responsible reviewer and next action. Avoid terms such as recoverable unless the relevant decision supports them.
- Connect the cause to the next estimate. Say whether the issue is finished, continues in remaining work or needs a further allowance. Identify the assumption to revisit and its date. A past cost remains past cost even if a better method reduces future exposure.
- Reconcile and edit. Check that the narrative amounts total to the report movement and use the same cutoff. Remove repeated explanations for unchanged items unless the issue needs a decision. Have someone unfamiliar with the event read the line before issue.
Common mistakes
- Writing due to site conditions without identifying the condition or affected work.
- Calling a disputed back-charge an agreed offset.
- Keeping the same narrative after the remaining-work estimate changes.
Checklist
Four parts beside the number
- Amount, direction and comparison basis.
- Specific cause with its evidence status.
- Recovery stage and next reviewer.
- Recorded cost versus remaining estimate.
- Next forecast assumption and review date.
Check your understanding
The cost cause is confirmed, but responsibility is disputed. Should the narrative omit the cause until the dispute is settled?
