1. A structural steel special inspector is assigned to a high-rise project
using ASTM A36 wide-flange members and ASTM A490 high-strength
bolts. Which of the following responsibilities best represents the
inspector’s primary duty during erection and connection work under
typical IBC Chapter 17 requirements?
A. Designing the steel framing system and approving shop drawings prior to
fabrication
B. Verifying conformance of materials, bolting procedures, weld quality, and
installation against approved construction documents and AISC/AWS
standards
C. Performing full-time structural engineering calculations for member sizing
and load redistribution during erection
D. Issuing change orders to modify connection details when field conditions
differ from drawings
B
A structural steel special inspector’s core function is to observe and verify
that steel materials, fabrication, and erection comply with approved plans
,and applicable standards such as AISC and AWS. The inspector does not
perform structural design or issue contractual changes, but instead
documents compliance and reports deviations to the design professional.
2. During inspection of high-strength bolted connections in a steel frame,
which condition most directly indicates a potential nonconformance
requiring corrective action?
A. Bolts are installed using calibrated tension control tools with documented
pre-installation verification
B. Faying surfaces are free of mill scale, oil, and debris prior to assembly
C. Bolts are tightened but show visible rotation beyond specified pretension
limits without verification
D. Bolt storage is maintained in a dry environment prior to installation
C
Excessive or uncontrolled bolt rotation beyond specified pretension
requirements suggests improper installation or failure to achieve required
tension, which directly affects structural integrity and must be investigated
and corrected under inspection protocols.
3. A special inspector observes welded beam-to-column moment
connections on a moment-resisting frame. Which of the following is
the most appropriate action when weld access holes and backing bars
are not installed per approved AWS D1.1 procedures?
A. Ignore the condition if the weld visually appears sound
B. Immediately accept the connection if the welder is certified
C. Document the deviation and report it to the contractor and engineer of
record
D. Redesign the connection in the field to compensate for missing details
C
The inspector must report deviations from approved welding procedures
and standards rather than accepting or redesigning work. Field correction
,decisions belong to the contractor and engineer of record, not the
inspector.
4. In structural steel inspection, what is the primary purpose of verifying
mill test reports (MTRs) for delivered steel members?
A. To determine the cost of fabricated steel elements
B. To confirm material chemistry, grade, and compliance with specified
ASTM standards
C. To calculate final building loads based on steel weight
D. To approve shop drawing revisions prior to fabrication
B
Mill test reports confirm that structural steel meets specified ASTM
requirements for strength and composition, ensuring that materials used
in construction conform to design specifications.
5. Which inspection requirement is most critical prior to the installation
of high-strength structural bolts in bearing-type connections?
A. Verification that bolts are painted for corrosion resistance
B. Confirmation of faying surface condition and pre-installation bolt
testing/calibration
C. Verification that bolts are installed without washers
D. Confirmation that bolts are tightened only after final building occupancy
B
Proper surface condition and pre-installation verification ensure that bolts
achieve required pretension and frictional resistance, which is essential for
structural performance in high-strength connections.
6. A steel column is observed to be out of plumb beyond specified
erection tolerances. What is the appropriate inspector response?
, A. Accept if the deviation does not affect aesthetics
B. Require correction and document nonconformance per specifications
C. Allow contractor to proceed if welding is complete
D. Approve the condition if base plates are fully grouted
B
Erection tolerances are structural requirements, and deviations must be
documented and corrected because they may affect load distribution and
structural stability.
7. Which of the following best describes the role of approved
construction documents in structural steel special inspection?
A. They are optional references used only if disputes occur
B. They define enforceable requirements used to verify compliance during
inspection
C. They replace all applicable building codes during construction
D. They are used solely for contractor pricing and bidding
B
Approved construction documents establish the binding requirements for
materials, installation, and tolerances, which inspectors use to determine
compliance with code and project specifications.
8. During bolted connection inspection, what is the significance of
verifying “turn-of-nut” method compliance?
A. It ensures bolts are painted correctly
B. It verifies bolt pretension through controlled rotation after snug-tight
condition
C. It replaces the need for bolt installation documentation
D. It confirms welding quality in hybrid connections
B
