module, resulting in cut units or unacceptable wide or narrow mortar joints. As an example of vertical dimensioning with modular brick, a 10’-0” high wall would work well, but a 9’-8” or 10’-4” high wall would split the required 8-in. module, since three bricks high with their corresponding bed joints course out to 8 inches.Īs an example of horizontal dimensioning with modular brick, a 20’-0” nominal dimension for wall length works well, whereas a 19’-10” or 20’-2” dimension would involve field-cutting of units at each course, or alternatively a drastic variation from the 3/8” wide mortar joint specified.

module in order to economically limit the masonry to only full and half units. Vertical dimensions like sill elevations and opening heights should be a multiple of the 8-in. long), horizontal dimensions like wall lengths and opening widths should be a multiple of the 4-in. Modular dimensioning in masonry is something many of us learned in architecture school, yet I often review drawings that show items like window sill elevations and opening sizes that do not fall on the typical masonry module, and therefore would require costly field cutting of masonry units. As a general rule, when using modular brick (which is nominally 4-in. Tip: Use modular dimensioning when establishing wall heights, lengths, sizes and locations of openings specify units by actual size, not nominal size.
