A reliable construction budget protects the owner and the builder. Budgets fail when they are built too early with too little information, or when they are never updated as the design develops. This guide lays out a budget process that works from concept to completion.
The Budget Lifecycle
Budgets mature in stages. At concept stage, use square foot or parametric ranges. At schematic stage, add assemblies and systems. At design development, price major divisions. At construction documents, build a detailed estimate that becomes the working budget.
Allowances and Contingency
Uncertainty is highest early in the project. Use allowances for items not yet selected and contingency for unknown conditions. A common approach reserves five to ten percent early and reduces it as drawings firm up. Our overhead and markup guide covers how to handle margin separately from contingency.
Tracking and Reconciliation
Budgets only work if they are tracked. Compare estimates against committed costs and actuals through the project. Reconcile change orders monthly and report variances by division. Discipline in tracking prevents surprises at closeout.
