    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Pleas see the attached case study table and questions to be answered.

    1. Develop a network drawing for Hill Construction and determine the critical path. How long is the project expected to take?
    2. What is the probability of finish in 270 days.

    3. If it is neccesay to crash to 250 or 240 days, how would Hill do so, and at what costs? As noted in the case, assume that optimistic time estimate can be used as crash times
