31. What is the purpose of a cost estimate in construction projects?
a) To determine the project schedule
b) To evaluate project risks
c) To provide a prediction of project costs
d) To calculate the cost of labor
View Answer
(Answer: c) To provide a prediction of project costs.
Explanation: A cost estimate is prepared to provide a prediction of the project costs based on the quantities, prices, and other factors associated with the construction project.
32. Which of the following is NOT included in the estimating process?
a) Gathering cost data
b) Analyzing project risks
c) Evaluating project schedule
d) Performing quantity takeoff
View Answer
(Answer: c) Evaluating project schedule.
Explanation: While project schedule is important for project management, it is not a direct component of the estimating process.
33. What is the purpose of a bill of materials in construction projects?
a) To determine the project schedule
b) To evaluate project risks
c) To provide a detailed list of materials required for construction
d) To calculate the cost of labor
View Answer
(Answer: c) To provide a detailed list of materials required for construction.
Explanation: A bill of materials lists all the materials required for construction, including quantities, specifications, and other relevant details.
34. Which of the following is NOT a common method of cost estimation in construction projects?
a) Analogous estimating
b) Parametric estimating
c) Vendor pricing
d) Bottom-up estimating
View Answer
(Answer: c) Vendor pricing.
Explanation: While vendor pricing may provide input for cost estimation, it is not a direct method of cost estimation itself.
35. What is the purpose of a cost code in construction cost estimation?
a) To determine the project schedule
b) To evaluate project risks
c) To categorize costs for tracking and analysis
d) To calculate the cost of labor
View Answer
(Answer: c) To categorize costs for tracking and analysis.
Explanation: Cost codes are used to categorize costs associated with different activities or components of a construction project for tracking and analysis purposes.
36. Which of the following factors is considered when calculating the cost of materials in construction projects?
a) Material type
b) Material quantity
c) Material quality
d) All of the above
View Answer
(Answer: d) All of the above.
Explanation: The cost of materials in construction projects depends on factors such as the type of material, the quantity required, and the quality or specifications of the material.
37. What is the purpose of a cost estimation report in construction projects?
a) To determine the project schedule
b) To evaluate project risks
c) To document the detailed cost estimation calculations and results
d) To calculate the cost of labor
View Answer
(Answer: c) To document the detailed cost estimation calculations and results.
Explanation: A cost estimation report provides a documented record of the detailed cost estimation calculations, assumptions, and results for a construction project.
38. Which of the following is a method used to estimate the cost of mechanical works in construction projects?
a) Quantity takeoff
b) Parametric estimating
c) Cost index method
d) Market research
View Answer
(Answer: a) Quantity takeoff.
Explanation: Quantity takeoff is used to calculate the quantities of mechanical components such as HVAC systems, piping, and equipment to estimate the cost of mechanical works.
39. What is the purpose of a cost database in construction cost estimation?
a) To determine the project schedule
b) To evaluate project risks
c) To store and organize historical cost data for reference and analysis
d) To calculate the cost of labor
View Answer
(Answer: c) To store and organize historical cost data for reference and analysis.
Explanation: A cost database is used to store and organize historical cost data, including material prices, labor rates, and other cost-related information, for reference and analysis in future cost estimations.
40. Which of the following is a method used to estimate the cost of landscaping works in construction projects?
a) Quantity takeoff
b) Parametric estimating
c) Cost index method
d) Market research
View Answer
(Answer: a) Quantity takeoff.
