Determine the project duration and critical path, Civil Engineering

Assignment Help:

Critical Path - Activity on Node

The project precedence table shown below provides the relationships and durations of all activities. Based on end-of-day calculations for starts and finishes, use a critical path analysis to determine the project duration and Critical Path.

Where there are multiple paths between subsets of activities, analyze the subsets to find the longest time path, then string together the longest subset paths to complete the critical path from start to finish.  To clarify the situation, sketch the project network, showing activities, durations, and the critical path.

a)    Total days to Finish = 41. 

 b)    The critical path is as follows:  START, A, B, C, D, F, G, FINISH
