Which of the following is the purpose of Rate Analysis?
- ATo determine the actual cost per unit of item
- BTo examine the item for economic processes and economic uses of materials involved in making the item.
- CBoth (A) and (B)Correct
- DNone of the above
Solution
Concept
Purpose of rate analysis in construction
Formula
NONE
Step-by-step solution
1. Rate analysis involves determining the cost of per unit work item based on quantities of materials, labor, and equipment. 2. It helps establish the actual unit cost required for estimates and tender preparation. 3. Additionally, it evaluates the process to explore economical uses of construction materials and methods. Answer: C
Explanation
Rate analysis evaluates the total cost of materials, labor, equipment, and overheads needed to complete a single unit of work. It helps determine the accurate unit cost while enabling engineers to explore more economical materials and efficient execution methods. Thus, rate analysis serves both cost determination and economic optimization purposes.
Why the other options are wrong
A) Rate analysis includes assessing economical material usage in addition to calculating unit cost. B) Rate analysis includes unit cost determination alongside analyzing economical processes. D) Options A and B are both correct purposes of rate analysis.
Shortcut
Rate Analysis = Both unit cost calculation and economic material evaluation.
Common mistake
Focusing solely on unit cost determination without considering the evaluation of economic processes and material utilization.
Correct answer: C) Both (A) and (B)
