Worked questions

1. During a steel-frame inspection, neither the markings nor the test records make the steel grade readily identifiable. Under 2021 IBC 2202.1, what is required to verify conformity?

  • Test the steel to verify conformity to the applicable standards.
  • BApply the specified grade label without testing or supporting records.
  • CAccept the steel solely because its dimensions match the drawings.
  • DAssume the highest grade shown anywhere in the project specifications.

Why A is correct

When markings and test records do not readily identify the grade, steel testing is required to verify conformity. Simply adding a label does not establish an unknown grade.

2. A legally occupied existing commercial building has a fire alarm installed under an earlier code edition. No alteration or occupancy change is proposed, and no unsafe condition or specific retrofit requirement has been established. Under 2021 IBC 102.6, what is the proper basis for deciding whether changes are required?

  • ARequire immediate replacement solely because the equipment predates the current edition.
  • BGive every existing system exactly one year to meet all new-construction requirements.
  • Check the applicable existing-building, fire and property-maintenance provisions for a specific requirement; age alone does not establish a blanket upgrade duty.
  • DTreat the installation date as permanent exemption from every safety or retrofit provision.

Why C is correct

Legal existing occupancy may continue subject to specific requirements in the IBC and the referenced existing-building, property-maintenance and fire codes. Neither an older installation date nor a new code edition alone decides every upgrade obligation. Work on existing buildings is governed through 101.4.7; actual safety or retrofit triggers must still be checked.

3. During a visual survey of an unreinforced concrete foundation wall, which crack pattern is more indicative of wall rotation associated with differential settlement than ordinary concrete shrinkage, according to FEMA P-50-1?

  • A crack that is wider at one end than at the other
  • BAn occasional narrow crack of uniform width with no displacement
  • CA superficial paint scuff that does not extend into the concrete
  • DA stain with no crack or movement in the wall

Why A is correct

FEMA describes tapered foundation-wall cracks as an indication that one or both sides have rotated, which can accompany differential settlement. Occasional even-width cracks in unreinforced foundations are commonly associated with shrinkage. A visual indicator warrants evaluation; it does not by itself establish the cause or prove imminent failure.

4. An approved agency prepares a special-inspection report under 2021 IBC 1704.2.4. What must the report indicate about the work inspected or tested?

  • AWhether the contractor met the project profit target
  • BWhether the project will finish on the original schedule
  • Whether the work conforms to the approved construction documents
  • DWhether the agency has taken over the contractor's construction supervision

Why C is correct

The report addresses conformity of the inspected or tested work to the approved construction documents. The reporting requirement does not transfer scheduling, business management or construction supervision to the inspection agency.

5. Which practice conflicts with U.S. Fire Administration electrical fire-safety guidance?

  • Overloading an outlet or power strip
  • BUsing a power strip with internal overload protection
  • CReplacing a worn or damaged extension cord
  • DUsing a lightbulb within the fixture recommended wattage

Why A is correct

Overloading is a fire-safety concern. The other choices describe precautions in USFA guidance. This is a safety-practice question, not a determination of a particular building enforcement procedure. Source: https://www.usfa.fema.gov/prevention/home-fires/prevent-fires/appliance-and-electrical/

6. Under 2021 IBC Section 2901.1 and its referenced 2021 IPC, what is the minimum uniform slope for a 2-inch horizontal sanitary drainage pipe in a commercial building?

  • ANo minimum slope applies
  • 1/4 inch per foot
  • C1/2 inch per foot
  • D1/8 inch per foot

Where to look it up

https://codes.iccsafe.org/s/IPC2021P1/chapter-7-sanitary-drainage/IPC2021P1-Ch07-Sec704.1

Why B is correct

IBC 2901.1 directs plumbing design and installation to the IPC. IPC 704.1 and Table 704.1 require at least 1/4 inch per foot for horizontal sanitary drainage piping 2-1/2 inches or smaller, including the stated 2-inch pipe. This gravity-drain rule does not establish a universal slope for pressure water-supply piping. The old combined supply-and-drainage question was too broad. The publisher’s full table and footnote also distinguish the grease-interceptor condition, which does not change the answer for the stated 2-inch pipe.
