ICC outline

The ICC 92 Prestressed Concrete Special Inspector path is now modular: first obtain Category 49 Reinforced Concrete Special Inspector, then pass 92C Codes and 92P Plans. Together the modules represent 90 multiple-choice questions over 3.5 hours in an open-book special inspector format. The official outline is dominated by reinforcement (48%) and prestressing/grouting (35%), so preparation should center on tendon condition, profiles, ducts, cover, stressing force, elongation records, concrete strength before transfer, grouting, anchorage protection, reports, and plan/specification checks.

Sample ICC Prestressed Concrete SI Practice Questions

Try these sample questions to test your ICC Prestressed Concrete SI exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1What is the special inspector's primary responsibility on a prestressed concrete project?

A.Design the tendon layout when field conditions change

B.Verify that prestressed concrete work conforms to approved plans, specifications, and code requirements

C.Select the concrete supplier and stressing subcontractor

D.Approve substitutions without involving the design professional

Explanation: The special inspector observes and verifies construction against the approved construction documents, applicable code provisions, and the statement of special inspections. The inspector documents compliance and reports discrepancies but does not redesign the work or approve unauthorized substitutions.

2During inspection, a tendon profile does not match the approved placing drawing. What should the inspector do first?

A.Tell the crew to continue and note it only in the final report

B.Immediately bring the discrepancy to the contractor's attention for correction

C.Move the tendon to the approximate correct location personally

D.Approve the tendon if the measured cover is still acceptable

Explanation: Discrepancies observed by the special inspector should be brought to the contractor's immediate attention so they can be corrected before concrete is placed. If the discrepancy is not corrected, it must be reported to the registered design professional and the building official according to the inspection procedures.

3Which item belongs in a final summary report for prestressed concrete special inspection?

A.A statement that required special inspections were performed and known discrepancies were resolved or identified

B.The contractor's internal cost breakdown for stressing work

C.A replacement for the registered design professional's structural calculations

D.A warranty that the structure will perform without future maintenance

Explanation: The final special inspection report summarizes the inspections and tests performed and states whether the work requiring special inspection was found to conform, with unresolved discrepancies identified if any remain. It is not a design document, cost record, or performance warranty.

4Before a prestressed concrete placement, what is the best use of the concrete batch ticket?

A.To verify the delivered mix corresponds to the approved mix for the element

B.To calculate tendon elongation for each stressing jack

C.To replace field testing of fresh concrete

D.To authorize a change in tendon spacing

Explanation: Batch tickets help the inspector verify that the concrete delivered is the approved mix and that recorded delivery information is consistent with project requirements. They do not replace required field tests or authorize changes to structural details.

5A ready-mix truck arrives for a post-tensioned slab. Which batch-ticket item is especially relevant to concrete quality inspection?

A.The color of the driver's hard hat

B.The time of batching and the amount of water added before discharge

C.The subcontractor's projected labor hours

D.The number of chairs installed under each tendon

Explanation: The inspector checks time-related delivery limits, water additions, approved mix identification, and workability because these affect concrete quality and strength. Tendon supports are important, but they are verified by field observation rather than the batch ticket.

6For fresh concrete used in prestressed construction, which activity is part of the inspector's concrete quality scope?

A.Observe sampling, field tests, and making of strength specimens when required

B.Eliminate all testing if the supplier has a good past record

C.Use visual appearance alone to accept concrete strength

D.Reduce the specified testing frequency to keep placement on schedule

Explanation: The official outline includes determining required tests and observing sampling, fresh concrete testing, and making test specimens. Supplier history and schedule pressure do not replace specified testing or acceptance procedures.

7Why must concrete strength specimens be identified, protected, and transported properly?

A.Improper handling can make test results unrepresentative of the concrete placed

B.Specimens are only decorative records for the project file

C.Specimen handling is the contractor's concern and never involves inspection

D.Testing laboratories reject every field-cured specimen automatically

Explanation: Incorrect identification, poor site storage, temperature damage, or mishandling can affect specimen strength and make results unreliable. The inspector must see that required specimen handling and protection arrangements are followed.

8Which strength information is most directly tied to allowing transfer or stressing of prestressing force?

A.The design strength expected at 28 days only

B.Evidence that the specified concrete strength for transfer or stressing has been achieved

C.The first slump result taken from the truck

D.The architect's approval of the concrete surface finish

Explanation: Prestressing force should not be transferred or applied until the concrete has reached the strength specified for that operation. That may require field-cured cylinders, approved maturity data, or other project-approved evidence depending on the documents.

9When prestressing strand is delivered to the job site, what basic item should the inspector verify?

A.Type, size, grade, and identification match the approved documents

B.The strand is painted the same color as the formwork

C.The strand supplier also provided the concrete mix design

D.The crew can identify it by memory without documentation

Explanation: The reinforcement domain requires verifying that tendons and reinforcing steel are the specified type, grade, and size and meet applicable quality requirements. Identification and documentation should be traceable to the approved submittals or project requirements.

10Which tendon condition should be reported before concrete placement?

A.Tendons are clean, correctly supported, and placed on profile

B.Tendons are free of excessive rust, dirt, and oil

C.Tendons have damaged sheathing and visible contamination at several low points

D.Tendons match the approved size and quantity

Explanation: Damaged sheathing and contamination can affect corrosion protection, bond behavior for bonded systems, and concrete quality around the tendon. The inspector should report and track correction of such discrepancies before the work is concealed.

ICC Prestressed Concrete SI Study Tips from Top Performers

1Start with the prerequisite: confirm your Category 49 Reinforced Concrete Special Inspector certification before planning 92C or 92P.

2Spend the most time on reinforcement and tendon placement because those two subjects dominate the official outline.

3Build a stressing-record checklist: jack calibration, sequence, tendon ID, gauge pressure, jacking force, measured elongation, seating, and discrepancies.

4Practice distinguishing the inspector's role from the engineer's role: observe, verify, document, and report; do not redesign or approve unauthorized changes.

5For the plans module, rehearse tracing tendon profiles, duct locations, anchorage zones, pour strips, construction joints, embedments, and specified cover from drawings to field checkpoints.

Frequently Asked Questions

What is the current ICC Prestressed Concrete Special Inspector path?

The current ICC path requires the Category 49 Reinforced Concrete Special Inspector certification first. After that prerequisite is met, the candidate must pass 92C Prestressed Concrete Special Inspector Codes and 92P Prestressed Concrete Special Inspector Plans.

How many questions are on ICC 92C and 92P?

ICC's store listings show 92C as 60 questions in 2 hours and 92P as 30 questions in 1.5 hours. The ICC content outline summarizes the combined certification as 90 multiple-choice questions with a 3.5-hour open-book limit.

What topics matter most on the ICC prestressed concrete outline?

The two largest official outline domains are Reinforcement at 48% and Prestressing and Grouting at 35%. That means tendon quality, cover, profiles, ducts, placement, stressing sequence, jack force, elongation records, grouting, and anchorage protection should receive most of your study time.

Is the ICC Prestressed Concrete Special Inspector exam open book?

Yes. ICC's content outline describes the combined exam as open book. Candidates still need fast reference navigation because the current path is split into timed 92C Codes and 92P Plans modules.

Does ICC publish a pass rate for this certification?

ICC does not publish an official pass rate for the Prestressed Concrete Special Inspector certification. ICC support states that national certification exams use a scaled passing score of 75, and the special inspector page requires passing both 92C and 92P.
