Calculation of the contingency coefficient C C∗=√χ2n+χ2, where χ2 corresponds to the χ2 statistic and n corresponds to the number of observations. When there is no relationship between two variables, C∗ is close to 0 .
Contingency costs can be incurred during any of the construction project phases. For example, a design error may lead to an unexpected increase in material expenses before ground-breaking. At the same time, a stretch of inclement weather might delay or complicate final detailing and sign-off steps.
The most basic way to calculate a contingency reserve is to add a fixed percentage to the total project budget, known as the Flat Rate method. Alternatively, if different percentages are applied to unique budget line items, this would be called a Mixed Rate method to establish the reserve.

You can calculate a contingency budget by identifying project risks, estimating their potential impacts, and assigning probabilities and dollar amounts to each. Multiply impact by probability to find the priority level, then sum their estimated costs based on your level of risk tolerance.
It provides a safety net for unexpected expenses and ensures the project stays on track, both in terms of budget and timeline. The recommended percentage for a contingency fund is between 5-10% of the total budget, but this may vary depending on project complexity and past experiences.

When determining a contingency for the contractor, the owner should consider the project's level of risk. A range of 5 to 10 percent is common, based on the level of risk, difficulty, and complexity the contractor will face.
