A perimeter fence required 11,200 units of 6” CHB to complete. If a mason has an average daily installation productivity of 320 units, what is its estimated duration for a crew of 5 mason/day
6 days
7 days
3 days
4 days
Draw the Network diagram given the ff:
A, B and C are starting activities and may begin at the same time.
D and E follows A and E is an ending activity
G follows and depends on C.
F is dependent on the completion of B and D.
G and F must be done before H, an ending activity, can start.
What is the Critical Path?
A=5, B=4, C=5, D=3, E=8, F=2, G=6 and H = 5 (all in days)
A-E
A-D-F-H
B-F=H
C-G-H
