Question 1: Under the International Building Code (IBC), what is the minimum required width for a means of egress corridor serving an occupant load greater than 50?
- 36 inches
- 44 inches (Correct answer)
- 48 inches
- 60 inches
Correct answer: 44 inches
The IBC requires corridors serving an occupant load greater than 50 to have a minimum clear width of 44 inches.
Question 2: Which federal regulation establishes the primary safety and health requirements for public construction projects involving federal funding?
- OSHA 29 CFR 1910
- OSHA 29 CFR 1926 (Correct answer)
- FHWA 23 CFR 635
- EPA 40 CFR 122
Correct answer: OSHA 29 CFR 1926
OSHA 29 CFR 1926 specifically governs safety and health regulations for the construction industry, including federally funded public works projects.
Question 3: When inspecting a public roadway curb ramp, which ADA requirement specifies the maximum running slope?
- 5%
- 8.33% (Correct answer)
- 10%
- 12.5%
Correct answer: 8.33%
ADA Standards for Accessible Design require curb ramp running slopes not to exceed 8.33% (1:12 ratio).
Question 4: According to AWWA standards, what type of joint is most commonly specified for ductile iron water main installations in public rights-of-way?
- Flanged joint
- Mechanical joint
- Push-on joint (Correct answer)
- Threaded joint
Correct answer: Push-on joint
Push-on joints (also called bell-and-spigot joints) are the most commonly specified connection for ductile iron water mains per AWWA C111/A21.11.
Question 5: A public infrastructure inspector finds a storm drain pipe installed with a grade of 0.1%. Which code provision is most likely violated?
- Maximum velocity requirement
- Minimum self-cleansing velocity requirement (Correct answer)
- Pipe bedding specification
- Manhole spacing requirement
Correct answer: Minimum self-cleansing velocity requirement
Most storm drain codes require a minimum slope sufficient to achieve self-cleansing velocity (typically 2 ft/s), which 0.1% grade would not achieve.
Question 6: Under NFPA 24, what is the minimum depth of cover required for a private fire service main installed in areas subject to vehicular traffic?
- 12 inches
- 18 inches

- AASHTO (Correct answer)
- ANSI
- ICC
Correct answer: AASHTO
AASHTO (American Association of State Highway and Transportation Officials) publishes the primary standard specifications for highway materials and testing used on public road projects.
