A framing assembly system for steel building that substantially reduces assembly time while maintaining excellent strength and mechanical integrity. In fabricating this type of building, foundation assemblies are first placed in concrete footings at a precise location in both the horizontal and vertical planes. Once the concrete has cured, columns are placed over the foundation assembly and bolted into place using pre-drilled holes in the columns and foundation assembly, thereby eliminating the difficult task of holding the columns erect while at the same time trying to precisely position the column in the horizontal and vertical planes. Trusses are connected to the top of the columns by means of bolts passes through pre-drilled holes. A series of holes centered in a straight vertical line at regular intervals enables the assemblers to adjust the height of the trusses by selecting an appropriate pair of holes through which to pass the bolts, thereby permitting assemblers to easily and quickly produce a desired roof pitch using only simple hand tools.
