1A candidate pursuing the current ICC reinforced concrete special inspector path should expect which ICC module set for Category 47?
A.Only the 47C Reinforced Concrete Codes module
B.Special Inspector General Requirements, 47C Reinforced Concrete Codes, and 47P Reinforced Concrete Plans
C.ACI Field Testing Technician Grade I only
D.S1 Structural Steel and Bolting plus S2 Structural Welding
Explanation: ICC lists Category 47 reinforced concrete as a modular path made up of the Special Inspector General Requirements module, 47C codes, and 47P plans. The GR module is not required again for candidates who already hold an active ICC Special Inspector certification. Full Category 49 credentialing also requires the applicable ACI/experience step.
2The legacy ICC Exam ID 47 outline for Reinforced Concrete Special Inspector describes what overall exam format?
A.60 multiple-choice questions, 2-hour limit, closed book
B.90 multiple-choice questions, 3.5-hour limit, open book
C.25 multiple-choice questions, 1-hour limit, closed book
D.Two essay questions and a field performance test
Explanation: The official ICC content outline for Exam ID 47 describes 90 multiple-choice questions, a 3.5-hour limit, and an open-book format. ICC now presents the path modularly as 47C and 47P, with GR when required, but the 90-question outline remains useful for studying the specialty scope.
3What is the primary purpose of reviewing the statement of special inspections before reinforced concrete work begins?
A.To replace the approved structural drawings with the inspector's field notes
B.To identify which concrete work, tests, and inspections are required for the project
C.To authorize the contractor to change reinforcing details without engineer approval
D.To determine the concrete supplier's delivery route
Explanation: The statement of special inspections defines the work that requires special inspection and testing. For reinforced concrete, it helps the inspector plan observations, sampling, report distribution, and required continuous or periodic inspection tasks. It does not override the approved construction documents.
4A special inspector observes reinforcing steel that does not match the approved drawings. What is the inspector's first required action?
A.Immediately redesign the reinforcing pattern in the field
B.Bring the discrepancy to the contractor's attention for correction
C.Ignore it if the concrete placement is already scheduled
D.Remove the reinforcing steel personally
Explanation: The inspector reports observed discrepancies promptly to the contractor so the work can be corrected. If the discrepancy is not corrected, it is elevated to the registered design professional and the building official as required by the inspection program. The inspector observes and reports; the inspector does not redesign or perform the work.
5Which report is normally used to close out required reinforced concrete special inspections for a project?
A.A concrete supplier invoice
B.A final special inspection report summarizing required inspections and unresolved or corrected discrepancies
C.The contractor's two-week look-ahead schedule
D.A delivery ticket from the final truck
Explanation: Special inspection programs require progress reporting during the work and a final report at closeout. The final report documents whether required inspections and tests were completed and whether discrepancies were resolved. Supplier paperwork may support inspection records but does not replace the final special inspection report.
6In the ICC reinforced concrete outline, which content area carries the largest share of the specialty exam scope?
A.Concrete Quality
B.Reinforcement
C.Formwork, Joints, and Embeds
D.Concrete Placement, Protection, and Curing
Explanation: Reinforcement is the largest outline domain for the reinforced concrete special inspector scope. That weighting reflects the field risk in bar size, grade, spacing, cover, hooks, splices, supports, and installed location before concrete hides the work. Candidates should be fast at navigating reinforcement requirements and plan details.
7If a candidate already holds an active ICC Special Inspector certification, how does that affect the GR module for another special inspector path?
A.The candidate must retake GR for every special inspector category
B.The candidate generally does not need to retake GR for the additional special inspector path
C.The candidate may skip all codes and plans modules
D.The candidate must take GR only after passing 47C and 47P
Explanation: ICC's special inspector modular guidance treats GR as a general module that is waived for candidates who already have an active ICC Special Inspector certification. The candidate still needs the codes and plans modules for the new category and must satisfy any category-specific prerequisites. For reinforced concrete, the later Category 49 step includes ACI/experience requirements.
8Which statement best describes the special inspector's authority when approved drawings conflict with field preferences?
A.The inspector may approve any change that appears stronger
B.The inspector verifies compliance with approved documents and reports deviations through the required chain
C.The inspector must accept the contractor's preferred detail if it saves time
D.The inspector has no role until concrete testing starts
Explanation: The special inspector is responsible for verifying that the work conforms to the approved construction documents and applicable code requirements. When field conditions or preferences differ, the inspector documents and reports the issue so the proper design and code officials can evaluate it. The inspector does not independently approve design substitutions.
9For full ICC Category 49 Reinforced Concrete Special Inspector certification, which additional requirement is tied to ACI after completing ICC Category 47?
A.An ACI masonry prism test only
B.ACI Concrete Field Testing Technician Grade I and reinforced concrete inspection experience evaluation
C.An AWS structural welding performance test
D.A NICET asphalt certification
Explanation: ICC's current reinforced concrete path distinguishes Category 47 module completion from the full Category 49 certification. Category 49 requires the reinforced concrete special inspector/experience evaluation process through ACI, and ICC notes the ACI Concrete Field Testing Technician Grade I requirement for obtaining the credential. This prevents candidates from treating the ICC module exams as the entire credentialing process.
10A candidate has passed 47C, 47P, and GR but has not completed ACI's reinforced concrete experience evaluation. What is the most accurate conclusion?
A.The candidate has completed the ICC Category 47 module path but has not completed all requirements for full Category 49 certification
B.The candidate is automatically an ACI Concrete Field Testing Technician Grade I
C.The candidate has completed the prestressed concrete special inspector credential
D.The candidate may ignore experience verification because the exams are open book
Explanation: Passing the ICC modules is not the only requirement for the full reinforced concrete special inspector credential path. ICC identifies additional ACI/experience requirements for Category 49. The open-book nature of the exams does not remove the need for verified qualification steps.

ICC Reinforced Concrete SI Study Tips from Top Performers

1Treat Category 47 and Category 49 separately: Category 47 is the ICC module path, while full Category 49 adds the ACI reinforced concrete experience evaluation and ACI Field Testing Technician Grade I requirement.
2Spend the most study time on reinforcement because it is the largest ICC outline domain: bar size, grade, cover, tolerances, supports, hooks, bends, placement drawings, lap splices, couplers, and weld coordination.
3Know the high-frequency ASTM field tests: C172 sampling, C143 slump, C1064 temperature, C231 or C173 air content, C31 cylinders, and C39 compressive strength.
4Practice plan navigation for 47P with structural notes, sections, schedules, beam and column details, slab openings, embed plans, and construction joint details.
5For open-book testing, tab references around IBC Chapter 17, concrete special inspection tables, ACI reinforcement cover and detailing provisions, ACI 117 tolerances, and concrete field-testing standards.

Frequently Asked Questions

What modules make up the current ICC reinforced concrete special inspector path?

ICC lists Category 47 reinforced concrete as Special Inspector General Requirements (GR), Reinforced Concrete Codes (47C), and Reinforced Concrete Plans (47P). GR is required when the candidate does not already hold an active ICC Special Inspector certification.

How many questions are on the reinforced concrete modules?

The ICC Store lists 47C as 60 questions in 2 hours and 47P as 30 questions in 1.5 hours. The GR module, when required, is listed as 25 questions in 1 hour. ICC's legacy Exam ID 47 outline summarizes the specialty scope as 90 multiple-choice questions in 3.5 hours, open book.

Is passing the ICC modules enough for full Reinforced Concrete Special Inspector certification?

No. ICC states that passing the modules is not all that is required for full reinforced concrete certification. Full Category 49 requires Category 47 plus the ACI reinforced concrete special inspector/experience evaluation step, including the ACI Concrete Field Testing Technician Grade I requirement to obtain the credential.

What does the ACI experience evaluation require?

ACI's applicant information lists routes based on education and verified reinforced concrete inspection experience: two years college/technical school plus two years experience, high school/equivalent plus three years experience, or five years verified work experience. The experience must cover reinforced concrete inspection responsibilities such as forms, reinforcement, embedments, fresh concrete testing, placement, consolidation, finishing, jointing, curing, protection, and formwork removal.

What score do I need to pass an ICC certification module?

ICC explains that national certification exams use scaled scoring and the passing scaled score is 75. Passing candidates receive a PASS result rather than a numeric score.

What should I study first for this exam?

Start with IBC Chapter 17 special inspection responsibilities and the ICC outline, then spend the largest block of study time on reinforcement because it is the largest official content area. After that, practice ASTM concrete testing procedures, construction joint and embed inspection, placement, consolidation, weather protection, curing, and plan-reading tasks for 47P.
