1.
What is the primary advantage of prefabricating structural
components?
A. Eliminating all engineering requirements
B. Reducing on-site construction time while improving
manufacturing consistency
C. Eliminating the need for inspections
D. Eliminating the need for foundations
Correct Answer: Reducing on-site construction time
while improving manufacturing consistency
Rationale: Prefabrication moves much of the work into a
controlled manufacturing environment, which can
improve quality control and reduce field assembly time.
2.
What is a modular building?
A. A building constructed entirely from concrete masonry
B. A building assembled from manufactured sections or
modules
C. A building without structural connections
D. A temporary building that cannot be occupied
,Correct Answer: A building assembled from
manufactured sections or modules
Rationale: Modular construction uses substantially
completed factory-built units that are transported to
the site and assembled.
3.
What is the purpose of shop drawings?
A. To replace the contract documents
B. To show fabrication and installation details for manufactured
components
C. To establish property ownership
D. To calculate payroll taxes
Correct Answer: To show fabrication and installation
details for manufactured components
Rationale: Shop drawings communicate fabrication
dimensions, connections, materials, and installation
information needed to manufacture and assemble
components.
4.
Which document normally establishes the required dimensions
and configuration of a prefabricated component?
A. Delivery receipt
B. Approved construction drawings
C. Employee handbook
D. Purchase invoice
Correct Answer: Approved construction drawings
Rationale: Construction documents establish the design
requirements that manufactured components must
satisfy.
5.
What is a dead load?
,A. Temporary construction workers
B. Wind pressure
C. The permanent weight of the structure and permanently
attached components
D. Earthquake forces
Correct Answer: The permanent weight of the structure
and permanently attached components
Rationale: Dead loads include the self-weight of
structural members, finishes, permanently installed
equipment, and other fixed components.
6.
What is a live load?
A. The weight of structural steel
B. Variable loads imposed by occupants, furniture, storage, and
similar uses
C. The weight of foundations
D. The weight of permanent roofing
Correct Answer: Variable loads imposed by occupants,
furniture, storage, and similar uses
Rationale: Live loads vary with occupancy and use and
are distinct from permanent dead loads.
7.
Why must prefabricated components be adequately braced
during transportation?
A. To improve their appearance
B. To prevent distortion and structural damage
C. To reduce insurance premiums
D. To eliminate the need for tie-downs
Correct Answer: To prevent distortion and structural
damage
Rationale: Transportation introduces vibration,
acceleration, braking forces, wind forces, and other
, stresses that can damage inadequately supported
components.
8.
Before lifting a prefabricated module, what should be verified
first?
A. Paint color
B. Lifting points, weight, rigging requirements, and approved
lifting procedure
C. Final landscaping
D. Interior furniture placement
Correct Answer: Lifting points, weight, rigging
requirements, and approved lifting procedure
Rationale: Safe lifting requires knowing the actual load
and using engineered or manufacturer-approved lifting
points and rigging procedures.
9.
What is the primary purpose of a crane's load chart?
A. To determine paint coverage
B. To determine the crane's allowable lifting capacity under
specified conditions
C. To determine concrete strength
D. To determine insulation R-value
Correct Answer: To determine the crane's allowable
lifting capacity under specified conditions
Rationale: Crane capacity changes with boom
configuration, radius, counterweights, and other
operating conditions.
10.
What is the danger of exceeding a crane's rated capacity?
A. Faster installation
B. Possible crane instability, structural failure, or dropped load
