Many methods and procedures are in use for erecting the structural portion of metal buildings .
The techniques of raising frames vary from erecting small clear spans and endwall frames in units
to erecting the larger clear spans and modular frames in sections . The erection methods used
depend strictly on the type of building, the available equipment, the experience level of the crews,
and the individual job conditions .
The variations in these factors preclude the establishment of a firm or specific set of erection
rules and procedures . Consequently, the erection operation must be tailored by the erector to fit
individual conditions and requirements . However, there are certain erection practices, pertaining to
structural members, which are in general use and have proven sound over the years . Descriptions
of these follow .
Erectors are cautioned not to cut primary members (rigid frame columns, rafters, end bearing
frame rafters, interior columns) . These are the primary support members for the frame and
are designed as such . Any cutting of these members may affect the structural stability . A
representative of Mueller’s must be consulted prior to attempting alterations of these members .
