openings are dimensioned to fall on 4-inch modular
lines. This approach reduces building costs by
coordinating building sizes with standard-sized
building materials. For example, studs with finish are
approximately 4 inches thick and are spaced on 16- or
24-inch centers. Plywood panels and drywall sheets
come in standard 4-foot by 8-foot sheets.
Figure 2-14 shows a modular light-frame house
used for a small residential building. The building is
laid out in such a way that standard modular-based
building materials can be used. Often, modular
construction is used to develop complete, finished
panels or rooms. This process allows standard-size
building parts to be fabricated, taken to the building
site, and erected into place.
Metric measurement is becoming more common
in the United States on construction working drawings.
NAVFAC drawings now have dimensions in both
metric and English. The metric scale is used in place of
the architects and engineers scales when measure-
ments and dimensions are in meters and centimeters.
