Construction budget forecasting

A budget is the starting position. A forecast is the current position.

Residential project budgets lose value when they remain static while quotes, variations, procurement and site conditions change. Forecasting keeps the expected final outcome current.

Static budget versus live forecast

Static

Budget

The approved commercial plan and allowances at a point in time.

Live

Forecast

The latest expectation of final cost after actual results, commitments and remaining exposure are considered.

Decision

Variance

The difference that tells management where margin is being gained, lost or still at risk.

The minimum inputs worth maintaining

  • Original and adjusted budget by cost category
  • Actual cost to date
  • Committed subcontract and material cost
  • Approved and pending variation position
  • Remaining cost-to-complete allowance
  • Current contract value and target margin
More data is not automatically better. The forecast only needs enough structure to support commercial decisions and accountability.

What good forecasting changes

Procurement

Trade packages can be corrected before missing scope becomes a late variation.

Cash and margin

The expected financial finish becomes visible before the project is substantially complete.

Reporting

Management receives a consistent explanation of what moved, why it moved and what action is required.
