Sensitivity analysis of a construction project total duration with Precedence Diagramming Method.

Construction project total duration is always a critical element for construction management. The object of the paper is to introduce Sensitivity Analysis of project total duration, versus basic parameters like standard production rates of resources or key resource availability. A model of an example project is realized with Precedence Diagramming Method (PDM). The effects of variations of productivity rates and of variation of the availability of key resources versus total project duration are observed, thus performing a sensitivity analysis with a heuristic method, in a simple way.
