Design PERT and CPM scheduling for following construction projects:

Characteristics of construction projects to make it amenable for analysis by PERT or CPM are:

$($a$)$ The project must consist of a well$-$defined collection of jobs or activities which when completed will mark the end of the project.

$($b$)$ The jobs must be such that they can be started or stopped independently of each other within a given sequence, $($e$.$g$.$ certain continuous flow processes such as oil refining, where jobs or operations must follow one after another with essentially no time separation, are not amenable for analysis by PERT or CPM$).$

Please calculate and find answer detailly step by step because I want to understand how calculate this type of exercises. And please don$$t put answers of other experts which answered this question before I asked you.
