Question 2

The workability of concrete is assessed through:
1) Slump test
2) Compaction factor test
3) Setting time of cement
4) Le-Chatelier’s apparatus

Question 3

Which of the following statements is/are correct for a non-critical activity?
1. It demands very special attention and action.
2. One can do with normal attention to this activity with some leeway for action.
Select the correct answer using the codes given below:

Question 4

Which of the following is/are the main drawback(s) in adopting bar charts?
1) All the activities are shown as being independent of each other
2) The sequence of activities is not defined at all
3) It is difficult to judge whether an activity is completed or not

Question 5

Time estimates of a project activity are:
topoptimistic time = 10 days.
tml, most likely time = 15 days.
tpcs, pessimistic time =22 days.
Variance in days for this activity as per BETA distribution is:

Question 6

Consider the following statements regarding tendering for a civil work:
1) Earnest money deposit (EMD) is a prerequisite to tender for a work.
2) It is not essential to call for the contractor’s credentials when a tender is invited.
Which of the above statements is/are correct?

Question 7

Activities A, B, C and D constitute a small project; their interrelationship, expected duration and standard deviation of this expected duration are shown in the figure, respectively. With a view to improving the speed of implementation, each of B, C and D are split into three equal segments, maintaining appropriate inter-relationships between A and each of these nine segments. What will be the standard deviation of the modified project duration after segmentation (to the nearest unit)?

Question 8

A project starts with activity A and ends with activity F. The precedence relation and durations of the activities are as per the following table: The minimum project completion time (in days) is _______.

Question 9

For a construction project. The mean and standard deviation of the completion time are 200 days and 6.1 days, respectively. Assume normal distribution and use the value of standard normal deviate Z = 1.64 for the 95% confidence level. The maximum time required (in days) for the completion of the project would be _______

List-I
A) Control charts for variables
B) Control chart for number of non-conformities
C) Control chart for fraction rejected
D) Activity time distribution in PERT
List-II
1) Binomial distribution
2) Beta distribution
3) Normal distribution
4) Poisson distribution
5) Exponential distribution
