completing and Plumbing The first bay
After the first intermediate or interior frames have been set, Mueller, Inc . recommends that all
purlins, girts, and eave struts be installed in the braced bay and the entire bay plumbed, aligned
and braced before proceeding further . If the building is designed without cable bracing, the erector
is responsible for providing temporary erection bracing .
When this bay is properly and accurately plumbed and braced, the remaining members, to a large
degree, will automatically plumb and align when installed . Only a final check of the building plumb
remains, and few adjustments, if any, will be necessary .
