A construction project consists of twelve activities. The estimated duration (in days) required to complete each of the activities along with the corresponding network diagram is shown below. Activity Duration (days) Activity Duration (days) A Inauguration 1 G Flooring 25 B Foundation work 7 H Electrification 7 C Structural construction - 1 30 I Plumbing 7 D Structural construction - 2 30 J Woodwork 7 E Brick masonry work 25 K Coloring 3 F Plastering 7 L Handing over function 1   Total floats (in days) for the activities 5-7 and 11-12 for the project are, respectively: Correct Answer 0 and 0

Explanation:

Total float can be determined once the activity times i.e. EST, EFT, LST, and LFT are known. Total float

FT = LST – EST= LFT – EFT

For activity 5 – 7,

EST = 38

EFT = 63

LFT = 63

LST = 38

FT = LST – EST = 38 - 38 = 0

For activity 11 – 12,

EST = 80

EFT = 81

LFT = 81

LST = 80

FT = LST – EST = 80 - 80 = 0

Statement (I): Crashing of project duration always increases the cost of the project on its completion, no matter what the indirect, or overhead, costs are. Statement (II): The critical path along the project activities network diagram is compressed in the process of investigating the crashing of the project duration, and not the non-critical activities, up to a certain stage of crashing.
