Question

question 8 of 10
which of these is a reason an engineer may choose to use a prefabricated building component?
a. she wants to try out a new material that is not typically used.
b. she wants to reduce costs.
c. the client wants the building to be one of a kind.
d. she is not on a strict timeline.

Explanation:

Prefabricated building components are made in factories in advance. Mass - production in factories often leads to cost - savings due to economies of scale. New materials (A) are less likely to be used in prefabricated components as they are usually standardized. A "one - of - a - kind" building (C) would require custom - made, not prefabricated, components. Prefabricated components are used to speed up construction, so being on a non - strict timeline (D) is not a reason.

Answer:

B. She wants to reduce costs.
