Which projection method shows all three principal views – front, top, and side views – on a single plane?
a) Orthographic projection
b) Isometric projection
c) Perspective projection
d) Oblique projection
View Answer
Answer: b) Isometric projection
Explanation: Isometric projection shows all three principal views of an object on a single plane, emphasizing equal measurements on all three axes.
In an engineering drawing, what does the arrowhead at the end of a dimension line indicate?
a) The reference point of the dimension
b) The midpoint of the dimension
c) The starting point of the dimension
d) The ending point of the dimension
View Answer
Answer: d) The ending point of the dimension
Explanation: The arrowhead at the end of a dimension line indicates the ending point of the measured dimension.
Which type of scale allows the engineer to measure distances on the drawing directly in their actual size?
a) Architectural scale
b) Engineering scale
c) Fractional scale
d) Ratio scale
View Answer
Answer: b) Engineering scale
Explanation: Engineering scales are designed to represent actual distances, allowing measurements to be taken directly from the drawing in real-world units.
Which estimating technique involves breaking down a project into smaller, manageable components and estimating their costs individually?
a) Parametric estimating
b) Analogous estimating
c) Bottom-up estimating
d) Three-point estimating
View Answer
Answer: c) Bottom-up estimating
Explanation: Bottom-up estimating involves estimating the cost of individual components and then aggregating them for the total project cost.
What does the term “contingency” mean in project estimating?
a) An additional amount included to cover potential risks and uncertainties
b) The total estimated cost of the project
c) The cost of labor and materials
d) The estimated duration of the project
View Answer
Answer: a) An additional amount included to cover potential risks and uncertainties
Explanation: Contingency is an extra amount added to the estimated cost to account for potential risks and uncertainties during the project.
In estimating, what does “BOQ” stand for?
a) Bill of Quantity
b) Budget of Quantity
c) Bill of Quality
d) Budget of Quality
View Answer
Answer: a) Bill of Quantity
Explanation: BOQ stands for Bill of Quantity, which is a detailed list of all materials, labor, and their quantities required for a construction project.
Which cost estimation method uses historical data from past projects to estimate costs for a new project?
a) Parametric estimating
b) Analogous estimating
c) Three-point estimating
d) Expert judgment estimating
View Answer
Answer: b) Analogous estimating
Explanation: Analogous estimating uses historical data from past projects that are similar in nature to estimate costs for a new project.
What is the purpose of a “cost code” in the estimating process?
a) To assign a unique identifier to each project activity for tracking costs
b) To calculate the total project budget
c) To allocate resources to different project tasks
d) To determine the project schedule
View Answer
Answer: a) To assign a unique identifier to each project activity for tracking costs
Explanation: Cost codes are used to assign unique identifiers to different project activities, making it easier to track and manage costs throughout the project.
