A contingent contract is a legal agreement in which the terms and conditions only apply or take effect if a specific event occurs. Essentially, the parties involved agree to perform actions or obligations based on the occurrence or non-occurrence of a particular event in the future.
What Is a Contingency? A contingency is a potential occurrence of a negative event in the future, such as an economic recession, natural disaster, fraudulent activity, terrorist attack, or a pandemic.
A contingency can cover a range of unexpected costs during a construction project. Some examples are unforeseen site conditions, changes in project scope, unplanned repairs, delays in timeline and regulation changes such as building codes or zoning requirements.
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.
Project contingency is simply the process by which you account for uncertainty in that estimation by factoring in any risk. This is then added to the original estimate to ensure the company is prepped for a worst-case scenario that could otherwise derail a project.
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.
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.
