determine the critical path via Critical Method Analysis. Applying AON or AOA model to calculate the minimum time of finishing the project with consideration of the delay of specified work path scenarios among onerous on-site activities.

Q1. The activities involved in a warehouse building project are given in Table 1. Prepare the network model and carry out the critical path calculations.

Table 1 : Given data for the warehouse building project Activity Immediate Predecessor(s) Duration (Weeks)

Activity	Immediate Predecessor(s)	Duration (Weeks)
A	None	1
B	None	15
C	None	3
D	None	7
E	C	8
F	A, E	3
G	A, E	10
H	E, F	22
I	E, F	10

J	C	10
K	I, J	5
L	D, K	7
M	I, J	12

Determine :

i) The critical path(s) for the warehouse building project.

ii) The planned project duration; and

iii) the new planned project duration if the activities B and D are delayed by 3 weeks and 10 weeks, respectively
