The intermediate or interior frames nearest the bearing endwall are usually erected first . This bay
usually contains the diagonal bracing . The proper completion and plumbing of this first bay is
extremely important to the successful completion of the building .

Although several methods are used to erect rigid frames, it has been found most satisfactory to
erect the columns first, tie them together with the girts and tighten the anchor bolts* . On small
spans and short eave heights, columns can often be set in place by hand without the use of
hoisting equipment .

Temporary bracing should always be installed as soon as sections are

lifted in place.

*The anchor bolt tension may need to be adjusted to seat the rafter .
