1. Maryland Special Inspector Bolting Certification is a structural special
inspection qualification typically required under building code
enforcement frameworks for verifying high-strength bolted
connections in steel construction. It aligns with special inspection
provisions found in the International Building Code (IBC) adopted in
Maryland jurisdictions, where inspection of structural steel bolting is
required to ensure safety and compliance of load-bearing connections
in buildings and infrastructure projects.
2. Which statement best describes the primary purpose of special
inspection in structural steel bolting under Maryland-adopted building
codes?
A. To replace the contractor’s quality control program entirely
B. To provide independent verification that installed bolted
connections comply with approved construction documents and code
requirements
C. To design structural steel connections on behalf of the engineer of
record
D. To certify welding procedures instead of bolting inspections
B
Special inspection exists to independently verify that construction
work, such as high-strength bolted connections, complies with
, approved plans and code requirements; it does not replace
contractor quality control or perform design functions.
3. What type of bolted connections are typically subject to special
inspection under structural steel provisions?
A. Only hand-tightened bolts in non-structural framing
B. High-strength structural bolts used in load-bearing steel
connections
C. Any bolts used in plumbing systems
D. Decorative fasteners used in architectural finishes
B
Special inspection focuses on high-strength structural bolts because
they are critical to structural integrity and must meet specific
installation and tensioning requirements under code standards.
4. Which governing model code is most commonly used as the basis for
special inspection requirements for steel bolting in Maryland
jurisdictions?
A. National Electrical Code (NEC)
B. International Building Code (IBC)
C. Uniform Plumbing Code (UPC)
D. International Residential Code (IRC) only
B
The International Building Code provides the primary framework for
special inspection requirements, including structural steel bolting
inspections adopted by Maryland jurisdictions.
5. What is typically the inspector’s role during inspection of high-strength
bolted connections?
A. Replacing improperly installed bolts
B. Supervising fabrication of steel members in the mill
C. Verifying proper bolt type, installation method, and tightening
method compliance
D. Designing connection details in the field
C
The inspector ensures correct installation practices such as bolt
grade, placement, and tightening procedures are followed according
to approved standards and specifications.
, 6. Which documentation is most critical for a special inspector
performing structural bolting inspections?
A. Contractor payroll records
B. Approved structural drawings and bolting specifications
C. Real estate ownership documents
D. Equipment purchase receipts
B
Approved drawings and specifications define the required bolt types,
installation procedures, and inspection criteria necessary for
compliance verification.
7. What is a common acceptance standard used in structural steel
bolting inspections?
A. OSHA excavation standards
B. AISC Specification for Structural Steel Buildings
C. ASTM C150 for cement
D. ASCE 7 wind load tables
B
The American Institute of Steel Construction (AISC) standards provide
detailed requirements for structural steel bolting and are widely used
in inspection criteria.
8. Which of the following is a key indicator of a properly installed high-
strength bolted connection?
A. Loose bolts for thermal expansion
B. Correct pretensioning of bolts where required
C. Use of mismatched bolt grades
D. Omission of washers to reduce cost
B
Proper pretensioning ensures that bolts achieve required clamping
force, which is essential for structural performance and load transfer.
9. What inspection activity is most directly associated with “turn-of-nut”
tightening method verification?
A. Checking concrete slump
B. Verifying bolt rotation after snug-tight condition
C. Measuring paint thickness on steel
D. Testing soil density
