CCI exam — which code sections are actually tested and do I need values memorized?
I'm about 10 weeks out from my CCI exam and trying to figure out what reference materials I should actually be drilling. The exam outline references ICC codes, ACI standards, and ASTM materials standards, but I'm not sure which ones get tested at the level where you need specific values memorized versus just understanding how to use the code. I've been a field inspector for 9 years, mostly residential and light commercial, and some of the structural concrete and masonry content feels heavy.
The content outline breaks down to roughly 30% on concrete inspection, 20% on soils and foundations, 20% on structural steel, 15% on masonry, and the rest spread across wood framing and special inspections. My concrete knowledge is strong from field work but structural steel is my weakest area — I've never done much steel connection inspection.
I'm studying about 2 hours a day on weekdays, so roughly 60 hours over 6 weeks before I taper. Planning to do a lot of IBC code section review and practice questions. What content tends to surprise people on this exam?
Nine years of field experience is solid prep for most of the exam. The questions tend to be practical — "you observe X on the job site, what do you do?" — rather than purely theoretical. Your field background will carry you further than you probably expect on the scenario questions.
The exam is open-book for some administrations but don't rely on that — if you're flipping through the IBC during the test you'll run out of time. Know the most frequently referenced sections well enough to find them in under 30 seconds. Concrete cover requirements and rebar splice lengths came up multiple times on mine.
Soils and compaction testing questions surprised me the most. Know your proctor density test, nuclear gauge procedures, and acceptable compaction percentages for different soil classifications and applications. That content is easy to underestimate if you're coming from a building inspection background.
Structural steel was my weak area too and I passed by focusing on connection types, bolt installation methods — snug-tight versus pre-tensioned — and the visual inspection criteria from AWS D1.1. You don't need to be a structural engineer, you need to know what to look for and when to call something out.
Spend about 8-10 hours specifically on steel and you'll be fine.
