What is the fundamental purpose of establishing appropriate contingency reserves for both cost and schedule in a construction project?

The fundamental purpose of establishing appropriate contingency reserves for both cost and schedule in a construction project is to proactively manage the inherent uncertainties and identified risks that are characteristic of complex project environments. Construction projects are subject to numerous variables, making it impossible to predict every eventuality with absolute precision during the initial planning phases. Contingency reserves serve as dedicated buffers to absorb the financial and temporal consequences of these *known unknowns*—risks that have been identified and analyzed, but their occurrence, timing, or precise impact remains uncertain. This approach safeguards the project's approved cost budget and planned schedule, preventing deviations....
