What is the purpose of contingency in project estimation?

The purpose of contingency in project estimation is to account for unexpected costs that may arise during the construction process. Every project carries inherent uncertainties, including potential price increases in materials, unanticipated design changes, unforeseen site conditions, and other risks that could lead to additional expenses. By including a contingency budget in the overall project estimate, project managers and estimators ensure that they have financial resources set aside to effectively manage these variables without derailing the project's financial health.

This practice allows for more accurate budgeting and helps avoid significant disruptions to the project timeline and scope. It is a proactive approach to risk management, ensuring that funds are available when they are needed and that the project can continue smoothly despite unforeseen challenges. In essence, contingency acts as a financial buffer that supports project completion even in the face of uncertainties.
