1. A method for modeling construction risk comprising:

  • providing a statistical model for each of a plurality of location-based tasks of a construction project model, wherein one of a plurality of work crews performs an associated one of each of the plurality of location-based tasks, wherein one of a plurality of first statistical models is related to a corresponding one of the plurality of work crews, and one of a plurality of second statistical models is related to a corresponding one location variable of each location-based task;

    randomly selecting a model parameter for each of the plurality of first statistical models and each of the plurality of second statistical models to generate a statistically-based duration for each of the location-based tasks;

    calculating a schedule duration based on the statistically-based durations of the location-based tasks; and

    repeating the steps of providing, randomly selecting, and calculating until a statistical distribution for the construction project model is generated.
