Exam AACE-PSP Topic 1 Question 140 Discussion

Actual exam question for AACE International's AACE-PSP exam
Question #: 140
Topic #: 1
There is only enough room for a maximum of 4 cranes to be placed on-site. Assuming that a single crane can perform 35 lifts per day and that a column pour requires 60 lifts, what is the minimum number of tower cranes that should be used for the above described column pours?

Suggested Answer: D Vote an answer

Column Pour Requirements:
Each column pour requires 60 lifts per day.
Crane Capacity:
Each crane can perform 35 lifts per day.
Determine Minimum Cranes Required:
Minimum Cranes = Column Lifts ÷ Crane Capacity = 60 ÷ 35 ≈ 1.71 cranes.
Since partial cranes cannot be used, round up to 3 cranes.
Cross-Verification:
Option A (2 cranes): Incorrect. Insufficient lifts per day.
Option B (1 crane): Incorrect. Infeasible.
Option C (4 cranes): Incorrect. Exceeds requirement.
Option D (3 cranes): Correct. Satisfies lift requirements efficiently.
