What Is the Chicago Brick Masonry Contractor B Card?

Chicago licenses mason contractors through the Department of Buildings. The City currently recognizes Class A, Class B, and Class C mason contractor licenses.

The B Card examination is the written examination associated with Brick Masonry Contractor qualification. Under the City's current classification system, a Class B Mason Contractor may perform masonry work except site-formed concrete work.

This distinction matters when choosing preparation materials. If you are taking the B Card exam, your study plan should focus heavily on masonry installation, brick and block systems, materials, tools, estimating, construction math, and OSHA safety.

Who Is the Supervising Mason?

A Chicago mason contractor business must have an individual who has passed the appropriate City examination and is qualified to supervise the masonry work performed under the contractor license.

The supervising mason is more than a name added to an application. The person is expected to provide real supervision for the masonry work being performed by the licensed business.

A B Card supervising mason should understand:

• Brick and concrete masonry units
• Mortar and grout
• Masonry wall construction
• Reinforcement and anchorage
• Control and expansion joints
• Flashing and moisture control
• Masonry tools and equipment
• Estimating and construction math
• OSHA construction safety

Current examination application materials also require candidates to be at least 21 years old. Always review the current City and Continental Testing Services application instructions before filing because forms, fees, and deadlines can change.

Chicago 302 Brick Masonry B Card Exam Format

Continental Testing Services administers the Chicago 302 Brick Masonry Contractor written examination for the City of Chicago.

Candidates may bring a non-programmable, non-printing, solar-powered or battery-powered portable or pocket calculator under the current testing rules. The guide also instructs candidates to bring two sharpened Number 2 black-lead pencils.

What Is on the Chicago Brick Masonry B Card Exam?

Continental Testing Services publishes the relative weight of each major B Card examination subject. These percentages are extremely useful when deciding how much study time each topic deserves.

Masonry Installations receives the greatest published weight at 25 percent, while Safety Regulations follows closely at 23 percent. That tells you something important before you study a single page. Installation and safety deserve a large part of your preparation.

The published percentages are rounded in the official guide, so use them as a study-weighting tool rather than trying to turn them into an exact question count.

Masonry Installations Should Be a Major Study Priority

Masonry Installations is the largest section of the B Card blueprint. Candidates need to understand how brick and masonry units are actually installed, supported, reinforced, joined, flashed, and finished.

Review topics such as:

• Brick laying procedures
• Concrete masonry unit installation
• Bond patterns
• Wall layout
• Mortar joints
• Reinforcement
• Anchors and ties
• Lintels and openings
• Control joints
• Expansion joints
• Flashing
• Cleaning and workmanship

Do not study these as disconnected vocabulary words. Picture the wall being built. Think about where the units go, how they are supported, where water might travel, and how movement is controlled.

Once you understand the wall as a system, installation questions become a lot easier than trying to memorize a pile of random facts.

Safety Regulations Are Nearly One Quarter of the Exam

Safety Regulations account for 23 percent of the published B Card blueprint. That makes OSHA preparation one of the biggest parts of the entire test.

Study construction safety involving:

• Scaffolds
• Ladders
• Fall protection
• Personal protective equipment
• Masonry saws
• Power tools
• Material handling
• Excavation hazards
• Access and working surfaces
• Chemical and cleaning hazards
• General jobsite safety

Safety questions can be easy points if you understand the rules. They can also become easy points to lose if your entire safety study plan is based on saying, "We have always done it this way."

OSHA requirements exist because scaffolds, saws, falling materials, heights, and heavy masonry units can create serious hazards. Study them as real jobsite rules, not just test trivia.

Know Your Masonry Materials

Masonry Materials represents 17 percent of the examination. Candidates should understand the materials used to create masonry walls and how their properties affect construction.

Review subjects including:

• Clay brick
• Concrete masonry units
• Mortar
• Grout
• Reinforcement
• Anchors and ties
• Sealants
• Flashing materials
• Moisture absorption
• Shrinkage and expansion
• Material storage

Material properties matter because masonry moves, absorbs moisture, dries, shrinks, expands, and interacts with the materials around it.

A brick is not simply a small red rectangle with excellent job security. Its absorption, dimensions, exposure conditions, and relationship with mortar can affect the finished wall.

Tools, Equipment, and Fasteners Matter Too

Masonry Tools, Equipment & Fasteners makes up 14 percent of the published exam outline. Experienced masons work with many of these tools every day, but the exam may test their correct use and safe operation.

Review equipment such as:

• Trowels
• Hammers and chisels
• Levels
• Masonry saws
• Mixers
• Scaffolding
• Lifting equipment
• Power tools
• Anchors
• Fasteners

Learn what each tool is designed to do, how it should be operated, and what safety steps apply.

Using the wrong tool can damage material on the job. Using the wrong answer on the exam mainly damages your score, but neither outcome is especially helpful.

Practice Quantity Surveying and Estimating

Quantity Surveying & Estimating represents 11 percent of the B Card outline. Contractors need to know how much material a project requires before the truck arrives with either far too much or not nearly enough.

Practice calculating:

• Wall area
• Brick quantities
• Block quantities
• Number of courses
• Mortar quantities
• Material waste
• Openings in walls
• Unit dimensions
• Linear measurements

Learn the difference between actual and nominal masonry-unit dimensions. Practice calculating courses and unit counts until the process feels normal.

Read every math question carefully. The exam may give you wall dimensions, unit dimensions, crew size, production numbers, or time and then ask for one very specific value.

Business Math Is Its Own Exam Category

Business Math also receives 11 percent of the published exam weight. Candidates should be comfortable solving basic construction and productivity problems without turning each question into a forty-minute accounting seminar.

Practice:

• Whole-number calculations
• Fractions
• Decimals
• Percentages
• Unit conversions
• Production rates
• Crew productivity
• Material costs
• Basic estimating math

A typical productivity problem might give you the total number of bricks installed, the number of masons working, and the number of hours worked. Your job is to determine the production rate per mason per hour.

Practice enough of these problems that you recognize the setup quickly. The calculator can do arithmetic, but it still expects you to know which numbers need dividing.

Which Books Are Recommended for the B Card?

The current Continental Testing Services candidate guide identifies three core references for both the B Card and C Card examinations.

Current listed references include:

• Masonry Skills, 7th Edition
• Concrete Masonry Handbook for Architects, Engineers and Builders, 6th Edition
• Code of Federal Regulations, Title 29, Part 1926 for OSHA construction safety

Candidates who want the listed preparation references organized together can review the Chicago Illinois Brick Masonry Contractor 302 B Card Book Package.

These books cover masonry materials, brick and block construction, installation methods, tools, drawings, estimating, calculations, and OSHA safety requirements.

You can also use the Chicago 302 Brick Masonry Contractor B Card Online Exam Prep Course if you prefer guided review, practice questions, and a structured study schedule.

The Chicago B Card Exam Is Closed Book

That means you should not spend all your preparation learning how to find answers in the books. Code and reference navigation can help while you are learning, but the final goal is understanding and recall.

1. Study the topic with the reference open.
2. Answer practice questions on that topic.
3. Look up every missed answer.
4. Explain the concept in your own words.
5. Repeat the questions without the reference.
6. Complete timed closed-book practice sessions.

If your practice routine involves looking up every single answer, you are still in the learning stage. That is fine. Just make sure you eventually move into closed-book practice before the actual exam.

Build Your Study Plan Around the Published Percentages

A simple study schedule can prevent you from spending too much time on one small topic while ignoring the sections that carry the most weight.

1. Begin with Masonry Installations. It carries the largest published percentage.
2. Study OSHA safety throughout your preparation. Safety is nearly as heavily weighted as installation.
3. Review Masonry Materials. Know how brick, block, mortar, grout, reinforcement, and accessories work.
4. Practice tools and equipment questions. Learn both proper use and safe operation.
5. Work estimating problems every week. Build speed with dimensions, quantities, and unit counts.
6. Practice Business Math. Do not save productivity calculations for the night before the exam.
7. Finish with timed closed-book practice. Train under conditions closer to the real test.

Use Practice Questions as a Study Map

A practice exam should do more than give you a percentage. It should tell you exactly what needs more attention.

When you miss a question:

1. Identify which B Card category it belongs to.
2. Find the related topic in the correct study reference.
3. Read enough surrounding material to understand the idea.
4. Write the rule or calculation in plain language.
5. Explain why your original choice was incorrect.
6. Try another question about the same subject later.

If Masonry Installations keeps showing up on your mistake list, study installation. If scaffold questions keep causing trouble, return to OSHA. If estimating math keeps winning the argument, work more estimating problems.

Your wrong answers are not just bad news. They are basically a free study schedule with slightly rude delivery.

B Card vs. C Card vs. A Card

Chicago's masonry classifications are easier to understand when you compare them directly.

What Happens After You Pass?

Candidates who earn a score of 70 or higher receive a passing notice and information for moving forward with the applicable Chicago licensing process.

Passing the exam demonstrates that you met the examination standard, but the contractor business still needs to satisfy the City's current mason contractor licensing requirements.

Keep your examination results, business information, supervising-mason documentation, insurance information, and other application records organized. Check current City instructions when applying because fees, forms, and procedures may change.

Prepare for Brick Masonry Work, Not Just a Passing Score

The Chicago 302 B Card exam covers topics that connect directly to real masonry construction. Materials matter. Mortar matters. Wall layout matters. Flashing matters. Expansion and control joints matter. Safety definitely matters.

Estimating matters too. Contractors need to calculate quantities, understand productivity, manage crews, and know whether enough material is arriving on the job before everybody discovers the answer at 2:30 on Friday afternoon.

Build your study plan around the official blueprint. Spend extra time on Masonry Installations and Safety Regulations. Learn materials and tools. Practice unit counts and business math. Then start removing your books from practice sessions so the closed-book exam does not feel like a completely different sport.
