How much contingency do I factor in? Industry standard for construction risk contingency is 3-10% of total hard costs. Some developers budget contingency for soft costs as well, typically 1% percent of total project costs or 10-20% of total soft costs.
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.
The JCT Standard Building Contract is designed for large or complex construction projects where detailed contract provisions are needed. Standard Building Contracts are suitable for projects procured via the traditional or conventional method.
How Is Construction Contingency Calculated? Typically, most construction projects use a contingency rate of 5% to 10% from the total project budget. This is typically enough to cover any unexpected costs that may arise throughout the project.
Set aside a well-researched contingency amount, typically between 5% and 10% of the overall project budget.
The Architect's Handbook of Professional Practice clarifies a contingency allowance as the amount, or percentage, included in the project budget to cover unpredictable changes in the work or items of work. It serves three core purposes: To account for errors and omissions in the construction documents.
Set aside a well-researched contingency amount, typically between 5% and 10% of the overall project budget. Allocate funds to cover the most likely and expensive contingencies first and then assign the remaining funds to cover the remaining events and risks.
This contingency is normally calculated as a percentage. If the phase is 100 days of effort, contingency at 20% would be another 20 days. As the project progresses, the level of risk reduces as the requirements and issues become known, so the percentage will be reduced.
