The document outlines the activity node diagram and critical path for building an ATC tower project. The critical path consists of activities A, B, C, D, and E which are expected to take a total of 27 weeks to complete. A delay of up to 5 weeks in designing the tower will not impact the overall project completion time since all parallel activities can still finish within the 27 week critical path.

ATC TOWER
Activity on Node Diagram:
Paths:
A, B, C, D, E
F, G, H, I, J, M, D, E
F, K, L, M, D, E
Critical Path:
A, B, C, D, E
Expected Time for Completion of the Project:
A, B, C, D, E
3 weeks + 2 weeks + 16 weeks + 2 weeks + 4 weeks = 27 weeks
Delay in Designing of Tower:
Delay of up to 5 weeks will not cause any delays in the overall project since the critical path
of the project is 27 weeks and within those 27 weeks all the parallel activities will be
completed even after the delay of 5 weeks.
