Question 1
What is the primary purpose of the Florida Building Code (FBC)?
A. To regulate contractor wages
B. To establish minimum construction standards for safety and durability
C. To set real estate property values
D. To approve contractor licensing requirements
B. To establish minimum construction standards for safety and durability
Rationale: The Florida Building Code is designed to ensure that all structures
built within the state meet minimum safety, structural integrity, energy
efficiency, and durability standards. It is not concerned with wages or property

A. Increase concrete color
B. Reduce curing time
C. Provide tensile strength
D. Improve insulation
C. Provide tensile strength
Rationale: Rebar (reinforcing steel) is embedded in concrete to improve its
tensile strength, as concrete is strong in compression but weak in tension.
