Understanding Budget at Completion (BAC)
BAC Components
Direct Costs
All costs directly attributable to project work, including labor, materials, equipment, and subcontractor expenses required to complete project deliverables.
Contingency Reserve
Budget allocated for known risks and identified uncertainties. Used for identified risks that have been analyzed but may still occur during project execution.
Management Reserve
Budget allocated for unknown risks and strategic opportunities. Controlled by project sponsors and requires formal approval for use.
Best Practices
Reserve Planning
Typical reserve levels range from 10-25% of direct costs, depending on project complexity, uncertainty, and organizational risk tolerance.
Baseline Management
BAC serves as the performance measurement baseline. Any changes require formal change control process to maintain budget integrity.
Cost Control
Regular monitoring against BAC helps identify variances early and enables proactive corrective actions to keep project on budget.
