$($b$)$ As a project manager, you have been given a task to handle a project of

constructing substructure works $($foundation and basement$).$ This project

demands many coordinated activities with varying durations and involves

numerous dependencies $($refer to Table $1).$

Therefore, using the information as depicted in Table $1,$ develop a

network diagram using the CPM technique by showing the early start

$($ES$),$ early finish $($EF$),$ late start $($LS$),$ and late finish $($LF$)$ times for each

activity involves in the project. Then, identify the critical path through the

network and float for each activity.
