- This article covers Registered Construction Inspector in Building: ACIA Division II Building, not any other credential sharing the RCI acronym.
- The technical exam has two parts: Codes & Standards (50 questions, three hours) and Plans & Specs (50 questions, four hours).
- The technical exam fee is $600, plus a separate $100-per-attempt Administration & Fundamentals prerequisite, for $700 on a first attempt.
- ACIA's own pages disagree on experience requirements and prerequisite details, so confirm both with ACIA before you apply.
What This Credential Actually Is
The acronym "RCI" is shared by several unrelated credentials, which causes real confusion for candidates searching online. This article is about one specific credential: the Registered Construction Inspector in Building, issued by the American Construction Inspectors Association (ACIA). The scope here is ACIA's Division II Building, not the umbrella program or another division.
If you are still orienting yourself, our explainers on what RCI certification is and what RCI stands for cover the naming question in more depth. The short version: this is a registration for people who inspect building construction for code and plan compliance, and the exam tests whether you can read codes, read drawings, and recognize defective work in the major trades.
The Two-Part Technical Exam Structure
According to ACIA's current exam page, the Building technical exam is split into two separate parts. They are not blended into one sitting, and the two question counts should not be mistaken for a statement about subject weighting.
| Part | Questions | Time Allowed | What It Emphasizes |
|---|---|---|---|
| Codes & Standards | 50 | Three hours | Locating and applying requirements from adopted codes and referenced standards |
| Plans & Specs | 50 | Four hours | Reading drawings and specifications and judging whether work conforms |
The exam line totals these two technical parts only: 100 questions across seven hours of allotted time. The separate Administration & Fundamentals prerequisite is a different exam, discussed below. Older instructions that describe open-book formats or different timing do not override this current two-part schedule, so ignore legacy forum posts that describe the exam differently.
Equal question counts do not mean each part carries an official 50% subject-domain weight. ACIA publishes no weighted domain breakdown for Building, which is why preparation has to be driven by the scope headings covered later rather than by invented percentages. For a deeper look at difficulty, see how hard the RCI exam is.
What the time allowance implies
Four hours for 50 plans-and-specs questions signals that these items are not quick recall. Expect to work with drawings, details, and specification language, then decide what a compliant installation looks like. Three hours for 50 codes questions likewise suggests lookups and cross-references rather than memorized trivia. Your preparation should build navigation speed through the code books, not just familiarity with their contents.
Fees and Registration Mechanics
The fee structure has two components, and candidates sometimes overlook the second.
- Technical exam fee: $600 for the Building technical exam.
- Administration & Fundamentals prerequisite: $100 per attempt, a separate exam.
- First-attempt subtotal: $700 by simple arithmetic ($600 + $100), excluding study materials, code books, or any other charges.
The $700 figure is arithmetic from those two published fees, not an all-in cost. Code books, practice materials, and travel or proctoring costs, if any apply, sit on top. Our RCI certification cost breakdown walks through how to budget for the full path.
Registration runs through the Everblue Exam Registration Portal, which ACIA links from its become-an-RCI page. Start from ACIA's own site and follow its link rather than searching for a portal independently, so you land on the correct system for this credential. For timing questions, see RCI exam dates and scheduling.
Eligibility: Two Sources, Two Answers
This is the section where careful reading pays off, because ACIA's own pages do not fully agree.
| Source | What It States |
|---|---|
| Onboarding / become-an-RCI information | Four years in the construction industry, verified through resume and employer verification |
| Rules and regulations page | High-school equivalence, good character, and five years with committee-approved credits, retaining one relevant inspection year |
These are different formulations, and the rules page involves a committee-approval element that the onboarding summary does not mention. Rather than guess which governs your situation, contact ACIA and ask which standard applies to your application and what documentation they expect. Candidates with mixed backgrounds, such as years split between field work, design, and inspection, should be especially careful, since the "committee-approved credits" language suggests individual evaluation. Our RCI requirements guide covers qualification pathways in more detail.
The prerequisite exam inconsistency
The Administration & Fundamentals prerequisite has its own documentation conflict. The shared exam-info page states a one-hour limit and a pass mark of 45 out of 59, while the Administration & Fundamentals Exam Overview PDF refers to 60 questions. Because 59 and 60 cannot both be right, treat the numbers as unresolved until ACIA confirms them. Do not build a pass-mark strategy around either figure. For the broader scoring picture, see the RCI passing score guide.
The Nine Technical Scope Headings
ACIA's Division II technical-examination subject list contains nine headings. They are an explicitly non-exhaustive, legacy scope list, unweighted and not nine verified current weighted domains. Treat them as a map of the territory a Building inspector is expected to know, not as a precise exam blueprint. Shared fundamentals and general-inspector material elsewhere in ACIA's instructions fall outside this nine-heading subset. For a walkthrough of how these areas fit together, see the RCI exam domains guide.
1. Foundations (piling and caissons)
Deep foundation work is inspected largely at the moment it happens, so candidates need to understand what the inspector is verifying in real time.
- Pile types, driving or installation records, and what deviations matter
- Caisson drilling, bearing verification, and reinforcement placement before pour
- Reading foundation plans and matching field conditions to the drawings
2. Earthworks (excavation and grading)
Earthwork inspection concerns whether the ground is prepared as designed before anything is built on it.
- Excavation limits, subgrade conditions, and bearing-surface verification
- Fill placement, compaction expectations, and grading to plan elevations
- Safety and stability considerations around open excavations
3. Sitework (pavements; utilities; fencing)
Sitework spans several distinct systems, each with its own installation and testing logic.
- Pavement base, subbase, and surfacing requirements
- Underground utility installation, bedding, and testing expectations
- Fencing layout, post setting, and conformance to plans
4. Landscaping and irrigation
Often underestimated, this heading rewards candidates who read the landscape drawings and specifications as carefully as the structural ones.
- Planting and soil preparation requirements in the specifications
- Irrigation layout, components, and pressure or coverage verification
5. Concrete work (including cast-in-place; shotcrete; pre stressed; light-weight; architectural concrete)
Concrete is a heavy topic because the scope list names five distinct variants, each with different inspection concerns.
- Cast-in-place: formwork, reinforcement placement, placement and curing
- Shotcrete application and quality considerations
- Pre-stressed concrete and the special care it demands
- Lightweight and architectural concrete, where finish and mix matter
- ACI 318 is on ACIA's reference list, so know how it frames requirements
6. Masonry work (including brick; concrete block; veneer construction)
Masonry inspection blends material conformance with workmanship details visible only during construction.
- Brick and concrete block units, mortar, and grout
- Reinforcement and anchorage in masonry walls
- Veneer attachment and how it differs from structural masonry
7. Structural steel framing systems (including high-rise construction)
Steel inspection centers on connections, welding, and erection sequence.
- Bolted and welded connection requirements
- AWS D1.1 appears on ACIA's reference list, so welding provisions deserve attention
- High-rise erection considerations and alignment
8. Metal joists and decking light-gage steel framing
Lighter steel systems have their own bearing, bridging, and fastening details that differ from heavy structural steel.
- Joist bearing, bridging, and attachment
- Metal deck installation and fastening patterns
- Light-gage framing assembly and connection details
9. Wood construction (including rough and finish carpentry; millwork; wood preservatives; diaphragm structures)
Wood spans everything from framing to finish work, with lateral-force systems called out explicitly.
- Rough framing and finish carpentry expectations
- Millwork and wood preservative treatment
- Diaphragm structures and how they resist lateral loads
Key Takeaway
Because the nine headings are unweighted, do not assume any heading is a safe skip. A candidate who knows concrete and steel cold but ignores landscaping and irrigation is gambling on what the question mix happens to contain.
Building Your Reference Library
Because the Codes & Standards part is about locating and applying requirements, your reference books are central tools, not optional extras. ACIA's current references list the 2018 editions of the IBC, IMC, IPC, and IFC. The issuer entry additionally reads "2018 NEC, International Fuel & Gas Code, AWS D1.1 and ACI 318."
- Confirm the NEC entry: The NEC listing is worth verifying with ACIA before purchase, since the reference line is worded unusually.
- Confirm unspecified editions: Several referenced standards do not state an edition. Ask ACIA which editions apply before spending money on books.
- Buy once, tab early: Whatever editions you settle on, start tabbing and annotating immediately so lookup speed develops alongside knowledge.
For a compact refresher once your books are in hand, the RCI cheat sheet collects the facts most worth memorizing, and the RCI study guide covers how to structure the full preparation arc.
Sequencing Your Preparation by Domain
Rather than studying the nine headings in list order, sequence them by dependency. Ground conditions come before foundations, foundations before superstructure, and structural systems before finishes. This also mirrors how an inspector experiences a project. A sample progression across six weeks follows; adjust the pace to your own schedule.
Codes orientation and Earthworks
- Learn the layout of your IBC and referenced books; tab major chapters
- Study excavation, grading, and subgrade verification
Foundations and Sitework
- Piling and caisson inspection points
- Pavements, utilities, and fencing; begin reading site plans
Concrete
- Cast-in-place first, then shotcrete, pre-stressed, lightweight, and architectural
- Work through ACI 318 provisions against sample details
Masonry and Structural Steel
- Brick, block, and veneer
- Steel connections and AWS D1.1 welding provisions
Light-gage, Joists, Decking, and Wood
- Metal joists, decking, and light-gage framing
- Wood framing, millwork, preservatives, and diaphragms
Landscaping, Plans & Specs drills, and review
- Landscaping and irrigation, then timed plan-reading practice
- Full pass through weak areas using practice tests
The reason for putting drawing-reading practice late is that it draws on everything before it. By Week 6 you have the vocabulary of each trade, so interpreting a detail becomes a matter of recognition rather than decoding. That said, start reading real drawings earlier if you can, since four hours for the Plans & Specs part rewards fluency.
Who Hires Building Inspectors
Building inspection work is found on both the public and private sides of construction. Municipal and county building departments need inspectors to enforce adopted codes during plan review and field inspection. Private-sector employers include special inspection and testing firms, engineering and construction-management consultancies, owners' representatives on large projects, and contractors that maintain internal quality-control staff. Because the scope headings span foundations through finish carpentry, the credential speaks to employers who need someone able to inspect across trades rather than a single specialty.
For a closer look at the job market, see RCI jobs. For compensation, we avoid quoting unverified numbers here; the RCI salary guide treats pay qualitatively and explains the factors that move it, and the ROI analysis helps you weigh the credential against your own situation.
Renewal and Membership After You Pass
Registration is not a one-time event. Renewal occurs every three years and requires 36 ACIA continuing-education units plus the applicable fee, as described on ACIA's renewal page. Initial successful registration includes three years of ACIA membership, so your first renewal cycle lines up with the end of that included membership period. Plan to accumulate continuing-education units steadily across the cycle rather than in a final-year scramble.
Frequently Asked Questions
Two parts: Codes & Standards with 50 questions in three hours, and Plans & Specs with 50 questions in four hours. Together they form the technical exam, separate from the Administration & Fundamentals prerequisite.
The technical exam fee is $600 and the Administration & Fundamentals prerequisite is $100 per attempt, giving a $700 first-attempt subtotal. That excludes books, study materials, or other charges. See the cost breakdown for planning.
No. They are an unweighted, non-exhaustive legacy scope list from ACIA's Division II instructions, not nine verified weighted domains. The two 50-question parts are also not official 50% subject weights.
ACIA's pages differ. Onboarding cites four construction-industry years with employer verification, while the rules page cites high-school equivalence, good character, and five years with committee-approved credits, retaining one relevant inspection year. Confirm with ACIA which applies. See the requirements guide.
Every three years, with 36 ACIA continuing-education units plus the applicable fee. Initial successful registration includes three years of ACIA membership.
ACIA's references list the 2018 IBC, IMC, IPC, and IFC, plus an issuer entry reading 2018 NEC, International Fuel & Gas Code, AWS D1.1, and ACI 318. Confirm the NEC entry and any unspecified editions with ACIA before purchasing.
Preparing for this credential means respecting its details: two technical parts, a separate prerequisite, nine broad scope headings, and a few places where ACIA's own documents need clarification. Resolve the ambiguities early, build code-lookup speed, and use realistic practice questions to test yourself against the format before you register.
