What is the purpose of a “bid bond” in the estimating and bidding process?
a) To guarantee that the project will be completed on time
b) To ensure the lowest bid is accepted
c) To provide financial security in case the contractor withdraws their bid
d) To secure funds for the project
View Answer
Answer: c) To provide financial security in case the contractor withdraws their bid
Explanation: A bid bond is a form of financial security provided by the contractor to the client to ensure that the contractor will proceed with the project if their bid is accepted.

In surveying, what does the term “benchmark” refer to?
a) A device used to measure angles
b) A known elevation point used as a reference for other elevations
c) A type of levelling instrument
d) A tool used to measure distances
View Answer
Answer: b) A known elevation point used as a reference for other elevations

Which surveying technique involves measuring angles and distances from two known points to determine the position of an unknown point?
a) Trilateration
b) Triangulation
c) Resection
d) Leveling
View Answer
Answer: b) Triangulation
Explanation: Triangulation involves measuring angles and distances from two known points to determine the location of an unknown point.
What is the purpose of leveling in engineering surveying?
a) To measure horizontal angles
b) To determine the position of survey points
