Question 2: Which ASTM standard governs the standard specification for ready-mixed concrete?
- ASTM C94 (Correct answer)
- ASTM C150
- ASTM C33
- ASTM C478
Correct answer: ASTM C94
ASTM C94 is the Standard Specification for Ready-Mixed Concrete, covering mixing, delivery, and uniformity requirements.
Question 3: The IBC requires a handrail on at least one side of a stair when the stair has how many or more risers?
- 2
- 3
- 4 (Correct answer)

- Underwriters Laboratories (UL)
Correct answer: National Fire Protection Association (NFPA)
The National Electrical Code (NFPA 70) is published by the National Fire Protection Association and is the basis for electrical installation requirements nationwide.
Question 5: Under the IBC, a building's 'occupant load' for egress design is primarily determined by:
- The number of parking spaces provided
- Dividing the occupiable floor area by the applicable occupant load factor (Correct answer)
- The building permit application estimate
- The sprinkler system design flow rate
Correct answer: Dividing the occupiable floor area by the applicable occupant load factor
IBC Section 1004.1 requires occupant load to be calculated by dividing the floor area by the occupant load factor from Table 1004.5.
Question 6: What does the acronym 'AHJ' stand for in the context of building codes and inspections?
