ALIGNING THE GIRTS
Installation of the building walls is generally done before the roof. Before starting the wall
installation, check to be sure that the eave strut and girts are straight and plumb. One method of
aligning the girts is to cut temporary wood blocking to the proper length and install between the
lines of girts. This blocking can be moved from bay to bay, which will reduce the number of pieces
required. Normally, one line of blocking per bay will be sufficient. Banding can also be used to hold
the girts straight and plumb.
Typical construction of the wood blocking is show below. A 2" x 4" minimum board size should be
used. Refer to the cross section framing drawing that accompanied the building to determine the
girt spacing.
