2027 Q&A| Instant Download Pdf
1. Which activity is most directly associated with a D-92
Prefabricated Steel Buildings contractor?
a. Installing residential carpeting
b. Erecting prefabricated steel building systems
c. Installing underground sewer mains
d. Performing landscape maintenance
Rationale: A D-92 contractor specializes in prefabricated steel building
systems, including the assembly and erection of structural
components that form these buildings.
2. Before beginning erection of a prefabricated steel building, what
should be verified first?
,a. Interior paint color
b. Foundation dimensions, anchor locations, and elevations
c. Landscaping plans
d. Furniture placement
Rationale: Accurate foundation dimensions and anchor-bolt locations
are essential because the steel framing must align precisely with the
designed support points.
3. What is the primary purpose of anchor bolts in a prefabricated
steel building?
a. To attach insulation
b. To support roof panels only
c. To secure the structural steel frame to the foundation
d. To connect electrical conduits
Rationale: Anchor bolts transfer forces from the steel framing into the
concrete foundation and provide the required connection between the
building frame and its base.
4. Which document normally provides the manufacturer's intended
sequence and details for assembling a prefabricated steel
building?
,a. Plumbing fixture schedule
b. Landscape plan
c. Erection drawings and manufacturer's instructions
d. Finish flooring schedule
Rationale: Erection drawings and manufacturer's instructions identify
component locations, connections, bracing requirements, and
assembly procedures.
5. Why is temporary bracing important during steel building
erection?
a. It improves the building's paint finish
b. It reduces insulation costs
c. It stabilizes partially erected framing until the permanent structural
system is complete
d. It replaces foundation anchor bolts
Rationale: During erection, the frame may not yet have sufficient
stability. Temporary bracing prevents movement or collapse until
permanent bracing and structural connections are installed.
6. Which condition can make steel erection particularly hazardous?
a. Dry interior walls
b. High winds acting on partially assembled framing and panels
, c. Low interior lighting after completion
d. Finished floor coverings
Rationale: Partially erected steel frames and large panels can act as
sails. Wind can impose significant lateral forces and create dangerous
instability during erection.
7. What is the purpose of checking column plumb during erection?
a. To determine insulation thickness
b. To establish roof color
c. To ensure columns are vertically aligned within the specified
tolerances
d. To determine electrical load
Rationale: Properly plumb columns are necessary for correct load
transfer, alignment of framing members, and proper installation of
roof and wall systems.
8. Which tool is commonly used to verify whether a steel column is
vertically aligned?
a. Pipe wrench
b. Plumb laser or level
c. Caulking gun
d. Tin snips
