Activity D takes 6 days to finish.
Activity F takes 5 more days to complete.
It is expected that it will take total 15 days to finish activity B.
Activity H cannot start until day 17 because of the delay of
material.
Q.6 (a) What are the typical responsibilities of a contractor at a construction site?
03
(b) In the Q.2(b) network, allocate the resources based on the early start and
04
late finish times of the network.
