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.
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 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.
The contingency allowance is the time allocated during planning for unscheduled events. Technical and personal disruptions result in changes in the indirect production costs. The contingency allowance is calculated in special contingency time studies, the results of which yield rates for indirect production costs.
Home builders and remodelers usually allocate between 5% and 10% of a project budget for a construction contingency. This amount creates enough breathing room for unexpected costs. Anyone tracking estimates and costs manually will calculate a contingency percentage on top of all costs before profit margins are applied.

: something (as an emergency) that might or might not happen or that might happen if something else occurs. prepared for every contingency.
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.
