Critical path
The longest path through the network; its activities have zero (minimum) float/slack.
PERT expected time
te = (to + 4tm + tp)/6; variance = ((tp − to)/6)².
Total float
TF = LFT − EFT = LST − EST. Free float ≤ total float.
Equipment selection
A crane provides full 3-D movement of loads on site.
3–5 questions in AE papers; the CPM/PERT theory is quick to revise and reliably tested.
Practise one full CPM network and one PERT problem — they cover most management MCQs.
Sample Construction Management MCQ
In CPM, the activities lying on the critical path have a total float equal to:
