Free Bachelor of Construction Management Trivia Questions and Answers — Questions and Answers
Question 1: Pick the false statement.
- Latest finish of an activity is the late event time of the node it enters.
- Latest start of an activity is its latest finish minus its duration.
- None of the above (Correct answer)
- Earliest start of an activity is the early event time of the node it leaves.
Correct answer: None of the above
All the provided statements (A, B, C, D) accurately describe concepts in Critical Path Method (CPM) scheduling. The latest finish of an activity is indeed the late event time of its succeeding node, and the latest start is its latest finish minus its duration. Similarly, the earliest start is the early event time of its preceding node. Therefore, since all statements are true, 'None of the above' is the correct choice, indicating that no false statement was found among the options.
Question 2: A machine costs Rs. 10,000,00 and is expected to last for 10 years. After ten years, the salvage value is Rs. 150,000. Using the conventional straight line approach of evaluating depreciation, the machine's book value after five years is
- Rs. 8,50,000
- Rs. 4,75,000
- Rs. 5,75,000 (Correct answer)
- Rs. 6,50,000
Correct answer: Rs. 5,75,000
To calculate the book value using the straight-line method, first determine the annual depreciation: (Cost - Salvage Value) / Useful Life = (1,000,000 - 150,000) / 10 = 85,000 per year. After five years, the total accumulated depreciation is 85,000 * 5 = 425,000. The book value is then the original cost minus accumulated depreciation: 1,000,000 - 425,000 = 575,000.
Question 3: A phony endeavor.
- Is represented by a dotted line
- Does not consume time
- All the above (Correct answer)
- Is artificially introduced
Correct answer: All the above
A dummy activity in project network diagrams is a logical connector that does not represent actual work. It is artificially introduced to maintain correct logical relationships between activities, is represented by a dotted line, and does not consume any time or resources. Therefore, all the given characteristics accurately describe a dummy endeavor.
Question 4: The independent float only impacts
- None of the above
- Preceding activities
- Succeeding activities
- The particular activity involved (Correct answer)
Correct answer: The particular activity involved
Independent float is the amount of time an activity can be delayed without affecting the earliest start time of any successor activity or the overall project completion time. Crucially, it also does not affect the latest finish time of any preceding activity. Thus, it only impacts the particular activity involved, allowing for flexibility within that specific task.
Question 5: Choose the untrue statement from the list below:
- The difference between the latest start time and earliest start time of an activity, is called total float
- The difference between the earliest start time and latest finish time of any activity, is the maximum time available for the activity
- The difference between the maximum time available for the job and actual time it consumes, is called total float
- None of these (Correct answer)
Correct answer: None of these
All the statements provided accurately define different types of float or time calculations in project management. Total float is indeed the difference between latest and earliest start/finish times, and the maximum time available is the difference between earliest start and latest finish. Total float can also be seen as the difference between the maximum time available and the activity's actual duration. Since all statements are true, 'None of these' is the correct answer as there is no untrue statement.
Question 6: Sheep foot rolling involves the fundamental movement of
- Vibration
- Kneading (Correct answer)
- Pressing
- Tamping
Correct answer: Kneading
Sheep foot rollers are compaction machines characterized by their drum covered with numerous protruding 'feet' or lugs. As the roller moves, these feet penetrate the soil, applying a kneading action that compacts cohesive soils from the bottom up, effectively reducing air voids and increasing density.
Question 7: Any activity's "free float" is defined as the difference between
- Its earliest finish time and latest start time for its successor activity
- Its earliest finish time and earliest start time for its successor activity (Correct answer)
- Its latest start time and earliest start time
- Its latest finish time and earliest start time for its successor activity
Correct answer: Its earliest finish time and earliest start time for its successor activity
Free float is defined as the amount of time an activity can be delayed without affecting the earliest start time of any immediately succeeding activity. It is calculated as the difference between the earliest start time of its successor activity and its own earliest finish time. This float allows for flexibility in scheduling a specific activity without impacting subsequent tasks.
