Draw the PERT/CPM chart longhand and show the critical path for the project above. You can develop and check your answers using a computer or software package. Attach additional print out sheets if necessary.

1. Using the PERT/CPM chart that displays activities, activity times, and activity predecessors for a construction project answer the following questions:

1. What is the critical path for the construction project?
2. What is the total time for the construction project?
3. What would you advise the project manager to do?

2. If the architect is delayed in preparing the drawings for the project in activity B by an additional 4 weeks (activity time of B changes from 4 to 8 weeks):

1. What is the critical path for the construction project?
2. What is the total time for the construction project?
3. What would you advise the project manager to do?

3. In addition to the delay in B) above, if the local authority closes the permit office due to a furlough and the granting of permits goes from 1 week to 10 weeks:

1. What is the critical path for the construction project?
2. What is the total time for the construction project?
3. What would you advise the project manager to do?
