Problem statement:
Submit an axonometric, isometric, or perspective drawing of a portion of a steel-framed building with stone veneer. The stone is used for both the vertical surface and horizontal soffit, as shown in the drawings below. It is only necessary to show the portion of the building shown in the schematic section at the bottom left (i.e., approximately a 6'x6'x6' section of the building).

Graphically show, as clearly as possible, the way in which all the elements of the cladding, insulation, air barrier, and structural support systems fit together. In order to show all the relevant connections and the full three-dimensional complexity, it will be necessary to cut-away, or "explode" the drawing to reveal things that would otherwise be obscure.

Additional requirements:
Base the drawing on the three images shown below: (1) the sketch at the left shows the general dimensions and placement of stone, insulation, air barrier, and structure; (2) the middle detail shows the connection hardware to be used, as well as a schematic indication of the steel angle sub-structure to which the connecting hardware is fastened; and (3) the detail at the right shows the way in which the rain screen cladding strategy is implemented (from Ronald Brand, Architectural Details for Insulated Buildings). Adapt the middle details so that they comply with the dimensional requirements at the left as well as the rain screen and air barrier theory illustrated at the right.

Note that the concrete slab can count as a horizontal air barrier. Also note that the dimensions for the stone and insulation are as shown in the detail at left (not as shown in the detail at right).

You may assume that each piece of stone is approximately 4-8 square feet in area, and supported by 4 fasteners, one near each corner. You may assume that the angles and clip angles shown in the middle detail are L4x4x1/4, and that all are continuous except for the angles immediately in contact with the stone veneer, which are clip angles approximately 4" in length. The maximum horizontal span of an angle supporting the stone can be asssumed to be approximately 4 feet. You may assume that the vertical yellow angles (you need to be online to see the colors) are supported by clip angles attached to the steel structural beams at each floor, and that the horizontal yellow angles are fastened (hanging) on threaded rods attached to the concrete slab every 4 feet.

The stone coursing on the facade is staggered so that vertical joints do not align from course to course.

Format:
Drawing may be done in any legible medium, and may be constructed freehand (over hardline base), hardline, or using modeling software. Final drawing may be drawn or reduced to 8-1/2" x 11" if it remains legible; maximum size is 11" x 17". Drawings must be flat -- do not roll up.

Academic Integrity:
"Course Assignments. Students are encouraged to discuss the content of a course among themselves and to help each other to master it, but no student should receive help in doing a course assignment that is meant to test what he or she can do without help from others. Representing another's work as one's own is plagiarism and a violation of this Code. If materials are taken from published sources the student must clearly and completely cite the source of such materials."
