Steel Building Structure

Tom puts up the skeleton for the new steel building addition.  After the concrete footings and floor were complete, it was time to erect the steel structure.  The main frame steel is put up first.  Those are the large steel girders and serve as the main support for the metal structure.  Tom started in the north bay first.  This is where the cable cross basing is located.  Two should go up at once and be tied together using purlins and girts.  Tom put enough purlins and girts on to at least temporarily hold the large beams in place.  It is important to stabilize the large beams using purlins and girts. 

The building package came with hardware to fasten the perlins and girts onto the main beams.  Bolts were screwed in by hand.  Bolts should be torqued twice by hand.  It is not recommended to use a rattle gun because it is hard to get a constant torque.
