Introduction
This comprehensive assessment evaluates knowledge and competency required for the ICC Structural
Masonry Codes Module (84C) Special Inspector certification. The exam consists of 200 multiple-choice
questions divided into two sections, assessing critical understanding of masonry construction inspection
procedures, material verification, code compliance, and professional responsibilities.
Questions cover foundational theory, applied professional knowledge, regulatory compliance, ethics, and
real-world inspection scenarios. The multiple-choice and scenario-based structure emphasizes real-world
application and decision-making skills necessary for special inspectors responsible for verifying that
structural masonry materials, reinforcement, and grout are installed according to approved plans,
specifications, and applicable building codes including IBC Chapter 21 and TMS 402/602.
SECTION ONE: QUESTIONS 1–100
,Question 1
What is the primary responsibility of a Structural Masonry Special Inspector during construction?
A. Design the masonry structural system
B. Verify masonry construction complies with approved plans and specifications
C. Prepare architectural drawings for masonry elements
D. Conduct final building occupancy inspections
🟢 B. Verify masonry construction complies with approved plans and specifications
🔴 RATIONALE: The Structural Masonry Special Inspector is responsible for enforcing construction details
contained in approved plans and specifications for structural masonry elements. This includes verifying
materials, placement of masonry, reinforcement, and grout are installed as shown and specified.
Question 2
Which standard governs the design and construction requirements for masonry structures?
A. ASTM C90
B. TMS 402/602
C. ACI 318
D. AWS D1.1
🟢 B. TMS 402/602
🔴 RATIONALE: TMS 402/602 is the Building Code Requirements and Specification for Masonry Structures,
which covers both design (TMS 402) and construction requirements (TMS 602) for masonry structures.
,Question 3
How often must a masonry special inspector observe grouting of reinforced masonry?
A. Once per project
B. Daily
C. Each lift or pour
D. Weekly
🟢 C. Each lift or pour
🔴 RATIONALE: Each lift of masonry that is to be grouted must be observed by the inspector to confirm proper
placement of reinforcement, grout consistency, and consolidation. This is required for reinforced masonry
construction.
Question 4
What is the minimum compressive strength requirement for load-bearing concrete masonry units (CMU) per
ASTM C90?
A. 1,500 psi
B. 1,800 psi
C. 2,000 psi
D. 2,500 psi
🟢 C. 2,000 psi
, 🔴 RATIONALE: ASTM C90 was revised to increase the minimum compressive strength of a unit from 1,900
psi to 2,000 psi (13.8 MPa) for normal weight concrete masonry units.
Question 5
Which section of the exam content outline covers the largest percentage of questions?
A. Materials
B. Masonry Placement
C. Reinforcement and Connector Placement
D. Grout Placement
🟢 C. Reinforcement and Connector Placement
🔴 RATIONALE: Reinforcement and Connector Placement represents 30% of the exam content, which is the
largest portion. Grout Placement is 24%, Masonry Placement is 21%, and Materials is 16%.
Question 6
What type of mortar is typically required for reinforced masonry construction?
A. Type N
B. Type S
C. Type O
D. Type K
🟢 B. Type S
