1. Which document should be reviewed first to determine the
intended dimensions, materials, and assembly requirements for a
prefabricated building?
A. Delivery receipt
B. Approved construction drawings
C. Equipment maintenance log
D. Employee time sheet
Rationale: Approved construction drawings provide the dimensions,
specifications, connection details, and installation requirements needed
to assemble the prefabricated building correctly. Installers should use
the approved plans rather than relying on assumptions or field
modifications.
, 2. What is the primary purpose of verifying the foundation before
installing prefabricated building components?
A. To determine the paint color
B. To calculate employee wages
C. To ensure the structure will be properly supported and aligned
D. To determine the delivery vehicle size
Rationale: The foundation provides the structural base for the
prefabricated building. Incorrect elevations, dimensions, anchor
locations, or alignment can prevent components from fitting correctly
and can compromise structural performance.
3. Before unloading prefabricated wall panels, what should the
installer verify?
A. The weather forecast only
B. The color of the panels
C. That the unloading area is stable, accessible, and free of hazards
D. That all interior finishes are complete
Rationale: Prefabricated components can be heavy, awkward, and
susceptible to damage. A stable and unobstructed unloading area
reduces the risk of injury, equipment instability, and material damage.
, 4. What is the main purpose of anchor bolts in a prefabricated
building?
A. To provide interior decoration
B. To connect structural components to the foundation
C. To replace roof sheathing
D. To seal windows
Rationale: Anchor bolts or approved anchoring systems transfer forces
between the building and its foundation. Proper location, size,
embedment, and installation are essential for structural stability.
5. If an anchor bolt does not align with the manufacturer's approved
connection detail, what should the installer generally do?
A. Cut the bolt off immediately
B. Bend the bolt until it fits
C. Drill random holes in the frame
D. Stop and obtain direction from the responsible designer, engineer,
or manufacturer
Rationale: Unapproved alterations to structural connections can
weaken the assembly. The discrepancy should be documented and
resolved using an approved procedure before installation continues.
, 6. What tool is commonly used to verify whether a component is
vertically aligned?
A. Tape measure
B. Pipe wrench
C. Level or plumb tool
D. Caulking gun
Rationale: A level can establish horizontal alignment, while a plumb tool
or vertical level reference can verify that a component is vertical. Proper
alignment is essential for accurate prefabricated assembly.
7. Why is it important to inspect prefabricated components
immediately after delivery?
A. To determine the final building color
B. To identify damage, missing components, or discrepancies before
installation
C. To eliminate the need for drawings
D. To determine the building's future resale value
Rationale: Early inspection allows damaged or missing components to
be reported before they interfere with installation. It also provides an
opportunity to document delivery condition and verify the shipment
against the material list.
