Problem statement:
The point of the drawing is to graphically show, as clearly as possible, the way in which all the parts of a typical steel-framed building fit together. In order to show all the relevant connections and the full three-dimensional complexity of such a structure, it will be necessary to cut-away, or "explode" the drawing to reveal things that would otherwise be obscure. Some examples of cut-away and exploded isometric and axonometric drawings are shown online. Additional images can be found within the ARCH 262/562 archives (Assign #2, Fall 2005)
Additional requirements:
The foundation consists of a continuous foundation wall and footing directly under the cladding. In addition, columns rest on 1'-0" square piers on 2'-0" square footings, overlapping the continuous footing of the wall as shown in the section. Steel beams can be assumed to be spaced 6' - 12' on center. While it is only necessary to show one column, it is recommended that at least two beams be drawn in order to clearly indicate how the corrugated steel deck is supported.
The column enclosure hides the column within the occupied space, but not above the suspended ceiling. It can be represented schematically as a thin surface (such as 1/2" gypsum board) with or without metal studs to support it. The HVAC unit enclosure shown in the section can be assumed to be continuous between column enclosures; it is not necessary to indicate any of the actual HVAC equipment, fans, or pipes within this thin sheet metal enclosure.
The scale of the drawing should not be indicated, and no dimensions should appear. However, all elements should be drawn to scale. For non-perspective renderings, a drawing scale of from 3/4"=1'-0" to 1-1/2"=1'-0" is probably a good place to start (the section shown here was initially drawn at 1"=1'-0").
