3.5 STRUCTURAL STEEL BUILDING FRAMING PRECAUTIONS

The layout, assembly and erection of steel buildings should be completed by responsible personnel, experienced in rigging and handling light steel members in a safe manner. Improper handling can easily result in injury, delays and unexpected added costs. This is particularly true when raising assembled rafters for wide buildings.

KEEPING STEEL BUILDING ERECTION COSTS DOWN

Minimum costs should be obtained when the following conditions are met during the erection of a RIGID building:

• 1. When safety practices are discussed and initiated in advance of any work procedure.
• 2. When the overall work of erecting the building is divided into individual jobs, and when each job is ssigned (in proper sequence) to teams of workers consisting of from two to seven workers each, with three to five worker teams preferred.
• 3. When individual workers are properly trained and instructed in advance as to what they are to do and the safe way to do it. This eliminates time wasted while waiting to be told what to do next.
• 4. When steel building parts are properly laid out according to advanced planning so as to avoid lost time in repetitive handling or in searching for specific items.
• 5. When as many parts as can be safely raised in a single lift are bolted together in sub-assem-blies on the ground where assembly work is faster and safer, thereby, requiring fewer lifts and fewer connections to be made in the air.
• 6. When erection of the steel framework starts at one end and continues bay by bay to the other end of the building.
• 7. When the first bay is completed, the individual frames are erected and tied together by skeleton purlins, and the fill-in purlins are installed after the costly lifting equipment has been released.
• 8. When tools and equipment of the proper kind, in good,safe condition, are available in sufficient quantity.
