Because the girders consist of three 2

Sills. Sill plates are most commonly 2 4s, 2 6s, 2 8s,
and 2 10s and are placed on the foundation so that the
length of sill plate required is the distance around the
perimeter of the building. Lengths ordered will depend on
the particular building. Not all frame buildings require a sill

plate, so the details should be checked; but generally, where

there are floor joists, there are sill plates.

The length of sill is often taken off as the distance

around the building. An exact takeoff would require that the

estimator allow for the overlapping of the sill pieces at the
