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.
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.
Generally, all construction contracts in Florida must contain are required to disclose the contractor or subcontractor's registration number issued by the Florida DPBR; if required. Furthermore, all construction contracts should also include a construction defect notice and opportunity to cure provisions.
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.
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.
Retainage is the withholding of a portion of the final payment for a defined period to assure a contractor or subcontractor has finished a construction project completely and correctly.
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.
For example, a conceptual estimate may have a contingency of 20% and an allowance of 10%, while a detailed estimate may have a contingency of 5% and an allowance of 2%. However, these percentages are not fixed and may vary depending on the project characteristics and the level of confidence of the estimator.
