Texture and color were adroitly used on precast concrete spandrel panels and load-bearing column covers to playfully relieve the monotony of a long, low building facade. Architectural precast concrete provided an aesthetically pleasing, durable and low maintenance exterior with extraordinary expensive qualities at a reasonable cost. The repetitive use of relatively simple flat panels with moderate changes in rustication provided a very economical, fireproof exterior treatment. Standard gray cement, limestone aggregate and black pigment mix with assertive reveals and light and medium sandblasted finishes to add interest and excitement to this office building. A system of column haunches, cast into the column cladding to support the spandrel panels, shortened erection time by minimizing connection time. A total of 1,212 precast panels provided 133,000 square feet of cladding.
Located just east of the McDonald’s Corporate Headquarters in Oak Brook, Illinois, this five story multiple tenant office building has 250,000 square feet of floor space. The modern architecture illustrates unique selections of precast concrete for color, form and texture. The lower base section is a batter wall shape that utilizes an irregular faced block form liner with a granite stone finish. The spandrel panels are ribbed and smooth with a combination acid-etched and sandblasted finish. The upper cornice panels have a diagonal face mitered corners, with inner and outer radius sections that project out from the face of the building approximately six feet. The cornice is white concrete with an acid-etch finish. This project consisted of 375 precast panels, approximately 46,000 square feet of precast surface area.

Highland Park High School was established in 1886. The school has been on the present site since 1900. Over the years, there have been several buildings and additions. With the latest addition, it was decided the most practicable and cost effective construction method would be precast concrete.
The high school addition needed to preserve the scale and quality of space in the existing school while integrating into the man-made and natural landscape. A facade featuring architectural precast panels with a limestone look joined with brick to create the color and texture required. Both wall panels plus sill panels that accent the existing brick were incorporated.
Here is an excellent example of how precast concrete additions can effectively be used for older existing buildings.
