Design Guidelines for Concrete Masonry Construction
Concrete Masonry units are typically manufactured with nominal modules (including the thickness of mortar joints) of 4 inches. These English unit conventions can be converted directly into metric equivalents. For example, an 8 x 8 x 16 inch modular concrete masonry unit has metric dimensions of 203 x 203 x 406 mm. NCMA recommends that buildings that are designed using metric measurements, use these "soft" metric dimensions. "Hard" metric units (200 x 200 x 400 mm) can be manufactured, but at possibly very large expense.
NCMA
is attempting to track metric construction projects in the
United States to determine the level of activity and added
complexity involved with these types of projects. Please
assist us by completing the information on metric projects
that you have been involved in to give us better insight
for representation on Capitol Hill. Complete as much of
the following information as you can. (For the background
on hard metric vs. soft metric, see the introduction to
the Metric Design Guidelines for Concrete Masonry Construction.)
We need only projects that have been awarded since the year
2000.
