Question 1
A required swinging egress door provides only 29 inches of clear opening width when opened 90 degrees. What is the usual minimum clear width for a standard egress door?
Correct Answer:
32 inches
Explanation:
The IBC generally requires a minimum clear opening width of 32 inches for required egress doors, measured with the door open 90 degrees between the face of the door and the stop, subject to specific exceptions.
Question 2
A contractor substitutes a different gypsum panel thickness in a listed fire-resistance-rated wall assembly. What should the inspector require?
Correct Answer:
Verification that the substitution is permitted by the approved listed assembly or an approved alternate
Explanation:
Fire-resistance ratings depend on the tested or listed assembly. Changing a component such as gypsum thickness is acceptable only when the approved system or an approved alternative specifically permits it.
Question 3
A load-bearing wood stud has a notch substantially deeper than permitted by the prescriptive framing provisions and no engineered repair is shown. What should the inspector require?
Correct Answer:
An approved repair or replacement consistent with the code and construction documents
Explanation:
Excessive notching reduces the cross section of a load-bearing stud. Field alterations beyond prescriptive limits require an approved engineered repair or replacement.
Question 4
An inspector finds a proprietary exterior wall panel system that is not prescriptively detailed in the building code. What should be verified before accepting the installation?
Correct Answer:
That the product has approval documentation and is installed in accordance with its listing and approved instructions
Explanation:
Products not specifically detailed by the code must be supported by approved evaluation or listing information and installed in accordance with the conditions of that approval. A warranty or prior use does not establish code compliance.
Question 5
Excavation for a spread footing exposes loose fill where the approved geotechnical report requires bearing on competent native soil. What should the inspector require before concrete placement?
Correct Answer:
Verify that the bearing surface is corrected or approved by the design/geotechnical professional before placement
Explanation:
Footings must bear on soil or engineered fill that satisfies the approved design assumptions. Loose or unsuitable material should be corrected or specifically approved before concrete is placed.
