What is the Medium Level 2 designation for Unit Masonry?

• A. Section 04 20 00 Unit Masonry
• B. Section 04 21 13 Brick Masonry
• C. Division 04 Masonry
• D. Section 04 00 00 General Masonry

Answer: (A)

MasterFormat assigns sections to specific material families within a division. For masonry, Division 04 covers the whole masonry scope, and the Level 2 designation narrows to the Unit Masonry family, which includes masonry units like brick, concrete block, and stone units. The code 04 20 00 corresponds to this Unit Masonry family, making it the correct designation. Brick Masonry is a more specific subsection within that family (a tighter, Level 3/4 detail), 04 21 13, which is why it isn’t the Level 2 designation. 04 00 00 General Masonry is a broader header, not the focused Unit Masonry section, and Division 04 Masonry refers to the entire division rather than a single section.
