What Makes Up a Project’s Cost?
A project’s cost is direct plus indirect plus risk plus profit — and understanding that structure is the condition of any sound estimate or control.
The full structure
Direct: materials, labour, plant and subcontractors attributable to particular items. Indirect: site management, engineers and supervisors, accommodation and catering, insurance and bonds, head-office overhead — all serving the project as a whole. Then a risk contingency, then a profit margin. A professional tender builds every layer explicitly rather than by instinct.
Loading and distribution
Indirects are either spread across the items as a percentage, usually of direct cost, or managed as a separate cost centre. Keeping the method consistent between estimating and control is what makes the comparison of actual against estimate fair.
The control cycle
A baseline budget from the estimate → actuals recorded against items as they occur → future commitments → item-level variances caught early → corrective action. Late discovery is the enemy: a month’s delay in spotting a variance doubles the cost of curing it.
Worked example
A typical SAR 10 million tender: 7.6m direct + 1.2m indirect (about 16% of direct) + 0.4m risk + 0.8m target profit. Dropping the indirects by oversight — a common beginner’s error — would have turned the profit into a loss before the first progress claim.
FAQ
How large are indirects usually?
As a guide, 8–20% of direct cost depending on the size and duration of the project and how remote it is — small, long projects carry the higher percentage.
What is the difference between cost control and accounting?
Accounting records what happened financially to the company; cost control compares what happened against what was planned at item level and forecasts the completion. The first serves compliance, the second serves decisions.
