What is Project Budget?
A project budget is a detailed financial plan that estimates the total cost of completing a defined project, broken down by category (labor, materials, equipment, subcontracts, overhead, contingency) and over the project’s duration. It is the baseline against which actual project costs are tracked through earned value management and variance analysis.
How It Works
- Build the work breakdown structure (WBS) defining deliverables.
- Estimate cost for each WBS element using bottom-up or parametric methods.
- Include a contingency reserve for known risks and a management reserve for unknown unknowns.
- Phase the budget across the schedule to create a cost baseline.
- Track actuals versus budget, manage change orders, and report variance.
Saudi Context
Vision 2030 giga-projects (NEOM, Red Sea Global, Diriyah, Qiddiya, Roshn) use multi-billion-riyal project budgets with sophisticated cost control. PIF and the implementing entities apply earned value management (EVM) and rigorous change management. Saudi contractors bidding on government work also use project budgets to compute their tender margins.
Example
A contractor’s project budget for a SAR 80 million construction project allocates SAR 30m to materials, SAR 22m to subcontracts, SAR 12m to direct labor, SAR 6m to equipment, SAR 4m to overhead, and SAR 6m to contingency. At month 6, actual cost SAR 38m vs budget SAR 35m flags a SAR 3m unfavorable variance requiring management action.
