ICC Prestressed Concrete SI study guide
ICC Prestressed Concrete SI · Work through your exam, one topic at a time.
The ICC Prestressed Concrete Special Inspector (SI) certification is a credential for inspectors who verify precast, prestressed concrete elements - both in the fabrication plant and in the field. It is aimed at quality-control technicians, plant inspectors, field inspectors, testing-lab staff, and engineering technicians who check pretensioned and post-tensioned members against approved drawings, specifications, and referenced standards. The ICC Prestressed Concrete SI study guide has 7 sections and about 2,150 words.
01Prestressing Materials and Components
Domain 1 of the ICC Prestressed Concrete Special Inspector exam covers the physical materials that make up a prestressed element and the accessories that anchor and protect the prestressing steel. Questions focus on identifying products, checking mill certificates against the specification, and recognizing matched anchorage systems.
334 words, about 2 min02Prestressing Steel: Strand, Wire, Bar, and Anchorage Systems
Domain 2 examines how strand, wire, and bar carry force, how each is anchored, and how the inspector confirms that the intended force actually entered the tendon. Pretensioned: strand is stressed in a bed before concrete is placed; force transfers by bond when the strand is released.
331 words, about 2 min03Concrete Materials, Mix Design, and Prestressed Concrete Properties
Domain 3 tests concrete that can carry high compression at transfer and then behave predictably over time. Expect mix-design, curing, cylinder testing, and camber questions.
298 words, about 1 min04Fabrication Plant Operations and Prestressing Procedures
Domain 4 covers what happens in the plant: bed layout, tensioning, concrete placement, detensioning, post-tensioning, and grouting. It rewards knowledge of hold points and documented measurements.
278 words, about 1 min05Inspection and Testing of Prestressed Concrete Elements
Domain 5 tests the inspector's hold points and the tests that prove an element complies: concrete strength, steel properties, dimensions, camber, and grout. Before placement: forms, strand or duct layout, cover, anchorage hardware, spiral confinement, lifting inserts, and embed plates.
287 words, about 1 min06Handling, Storage, Transportation, and Erection
Domain 6 covers what happens after the plant: lifting, storage, transport, and erection. Handling stresses can exceed design stresses, so the inspector verifies that supports and lift points match the design.
311 words, about 2 min07Code Compliance, Referenced Standards, and Inspector Responsibilities
Domain 7 tests the code framework and the inspector's professional duties: what must be inspected, when, and how nonconformance is reported. IBC Chapter 17 establishes special inspection and structural observation requirements; the prestressed concrete special inspector works under it.
