• Stapleton Business Center Building D-4

Located at the main entry to a business park right off a major freeway, this facility serves as the gateway to the park, which made curb appeal extremely important.

The design utilizes four large curved walls at the corners. Each wall ends with a flying panel separated from the rest of the building by a glass wall. The curved wall is segmented for speed of panel forming. Double-sided panels give the back side a finished look with substantial thickness. The steel/aluminum entry canopy pierces the last segment of the curve, which required close coordination between the steel and concrete panel during design and erection.

The building was erected in two phases to enable other trades to work while panel casting continued to ensure the fast-track schedule was met.

All four corner entries feature a segmented arched entry that utilizes eight 9-foot, 8-inch-wide panels with beveled edges that were placed on the radius segment. Each entry also has a double-faced freestanding panel with double-faced spandrel panels bearing on those panels and pilasters poured on the segmented panels.

Rooftop screening was a major concern because of the project’s close location to the highway. Screening was accomplished by using taller parapet panels and pouring stand up return legs on several panels.
