Exam Snapshot: The Numbers You Must Memorize
Before you open a single textbook, lock in the raw mechanics of the Alabama Building Construction (Commercial) General Contractor Trade Exam. This is the NASCLA Accredited Examination for Commercial General Building Contractors, delivered through PSI on behalf of the Alabama Licensing Board for General Contractors. Every candidate pursuing the Building Construction (Commercial) classification sits this exact test.
- Cost: $106 per attempt
- Length: 115 questions
- Time limit: 5 hours 30 minutes
- Passing score: raw score of 81
- Delivery: computer administered, open book
- Calculator policy: silent, nonprinting, nonprogrammable only
- Unscored items: up to 1-10 experimental questions may appear, and they count against your time
Because the exam is open book, memorization matters less than knowing exactly where information lives in your references and how fast you can retrieve it under a ticking clock. For a full explanation of what "passing" actually means on the raw-score scale, see AL-GC Passing Score 2026: Exactly What You Need to Pass.
Registration & Eligibility Mechanics
Passing the trade exam is only one piece of licensure. The Alabama Licensing Board for General Contractors requires a full application package before you're even approved to sit for the test, and understanding this sequence prevents wasted attempts.
- Obtain Board approval before scheduling anything
- Pay the $300 prime application fee (separate from the $106 exam fee)
- Designate a qualifying party for the license
- Register with the Alabama Secretary of State
- Carry liability insurance
- Submit a current CPA or approved-accountant financial statement showing at least $10,000 in both net worth and working capital, with no deficits
- Document at least three relevant projects
- Provide three qualified references
You'll also need to pass a separate Alabama Business and Law exam - this is not part of the 115-question trade exam and should be studied on its own track. Once approved, your eligibility window lasts one year, during which you get unlimited attempts at the trade exam. That window is generous, but don't waste it: schedule your first attempt with a real study plan, not as a "practice run." Prime licenses, once granted, renew annually for $200.
Remember that Alabama general-contractor licensure applies to projects of $100,000 or more - this threshold is the entire reason the license exists, and it shapes which questions the exam asks about contract scope, bonding, and project documentation.
For the complete step-by-step breakdown of every prerequisite, read AL-GC Requirements 2026: Eligibility, Prerequisites & How to Qualify. If you want a line-item cost comparison across the whole licensure path - not just the exam fee - check AL-GC Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Budget for $106 (exam) plus $300 (prime application) as separate line items, and gather your CPA financial statement early - it's the slowest-moving piece of the package.
The 12 Domains, Fast
The trade exam draws from twelve content domains covering the full scope of commercial building construction. Here's a rapid-fire reference; for deep coverage of each area, see AL-GC Exam Domains 2026: Complete Guide to All 12 Content Areas.
Domain 1: General Requirements
Covers project administration basics - submittals, safety, project closeout, and general conditions that frame every job.
- Know standard project documentation flow
Domain 2: Site Construction
Earthwork, grading, utilities, and site prep concepts that a general contractor must supervise or coordinate.
- Understand sequencing of site work before vertical construction
Domain 3: Concrete
Mix design basics, formwork, reinforcement, and curing - foundational to almost every commercial structure.
- Focus on placement and inspection points
Domain 4: Masonry
Unit masonry systems, mortar types, and structural masonry coordination with other trades.
Domain 5: Metals
Structural steel, metal fabrications, and connections common in commercial buildings.
Domain 6: Wood
Rough carpentry, finish carpentry, and wood-based assemblies used in commercial framing.
Domain 7: Thermal and Moisture Protection
Waterproofing, insulation, and roofing systems - a domain with heavy overlap into building envelope failures.
Domain 8: Doors, Windows, and Glazing
Openings, hardware, and glazing systems, including how they integrate with the envelope.
Domain 9: Finishes
Interior finish systems and coordination sequencing near project closeout.
Domain 10: Mechanical and Plumbing Systems
Coordination knowledge for HVAC and plumbing scope as a general contractor, not a specialty design deep-dive.
Domain 11: Electrical Systems
General coordination knowledge of electrical systems as they intersect with the GC's oversight role.
Domain 12: Procurement and Contracting Requirements
The largest domain on the exam. Covers bidding, contract types, bonding, insurance, and procurement procedures - the business backbone of commercial general contracting.
- Allocate the most study hours here
- Expect the highest concentration of scenario-based questions
Format Rules: Open Book, Calculator, Timing
The open-book format changes exam strategy fundamentally compared to closed-book credentialing tests. You're allowed reference materials, which means the test is designed to assess application and lookup speed rather than raw recall. A silent, nonprinting, nonprogrammable calculator is permitted - confirm your device meets that spec before test day, since anything programmable or with print capability will be rejected at check-in.
Because up to 1-10 unscored experimental questions may be mixed into the 115 and they count against your 5-hour-30-minute limit, don't try to guess which questions are "real." Treat every item with equal seriousness and keep a steady pace instead of hunting for the trick questions.
Candidates consistently underestimate how much time flipping through references costs. If your book isn't tabbed and indexed before test day, you will lose minutes per question searching blindly. For a broader look at how challenging this format is relative to other trade exams, see How Hard Is the AL-GC Exam? Complete Difficulty Guide 2026, and for data-driven context on outcomes, review AL-GC Pass Rate 2026: What the Data Shows.
| Element | Detail |
|---|---|
| Question count | 115 |
| Time allowed | 5 hours 30 minutes |
| Passing score | Raw score of 81 |

Who This License Actually Unlocks
Alabama licensure under the Building Construction (Commercial) classification is required for general-contractor work on projects of $100,000 or more. That threshold is the practical reason employers care about this credential: commercial developers, institutional owners, and public agencies routinely require a properly licensed prime contractor before a bid is even considered.
Holding this license - with the qualifying party correctly designated and the prime license active - positions a contractor to pursue larger commercial scopes than an unlicensed or residential-only operator could touch. If you're weighing whether the licensing process is worth the time and fees involved, Is the AL-GC Certification Worth It?

Final Week Review Sequence
With a one-year eligibility window and unlimited attempts, there's no excuse to rush - but there is a smart way to sequence your final weeks before test day. Because Procurement and Contracting Requirements carries the most weight, it should anchor your last review block, not get squeezed in as an afterthought.
Envelope & Structure Domains
- Concrete, Masonry, Metals, Wood - review assemblies and inspection points
- Tab your open-book references for these sections now
Systems & Finishes Domains
- Thermal and Moisture Protection, Doors/Windows/Glazing, Finishes, Mechanical/Plumbing, Electrical
- Practice locating code references quickly rather than memorizing values
Procurement and Contracting Requirements
- Deep review of the largest domain - bonding, contract types, bidding procedure
- Run timed practice sets to simulate the 5-hour-30-minute limit
Full Simulation & Cleanup
- Site Construction and General Requirements final pass
- Full-length timed run mimicking the 115-question format with your actual reference books
This sequencing is deliberately weighted toward the largest domain in the final stretch, when recall is freshest heading into test day. For a fully detailed study methodology built around this same domain structure, see AL-GC Study Guide 2026: How to Pass on Your First Attempt. You can also run full-length timed simulations on our practice test platform to get comfortable with the pacing before you sit the real exam.
Key Takeaway
Schedule Procurement and Contracting Requirements as your final deep-review domain - it's the largest on the exam and benefits most from being fresh on test day.
