Project Overview
The Circle Point office building is a total precast solution. The kinked floor plate is typical for a Class A -5 story structure. The total gross area is 340,000 sq. ft. with about 68,000 sq. ft. per floor. The precast floor and roof components include double tees and prestressed beams. The lateral system is made up of four shafts with cast-in-place topping on the floor and double tees serving as the diaphragm. At the roof level, the double tees are connected to act as a diaphragm without topping. The enclosure is highly accented in architectural precast and serves as the exterior perimeter gravity system, vapor barrier and air barrier.
Here, the Stresscon production department applied their skilled expertise for these monolithic one-piece columns. Produced with monolithic one-piece columns and an acid etch finish, the member is exposed on all four sides along with a four-sided reveal wrap to the windows.
This complex building enclosure is made up of architectural precast manufactured to PCI MNL 117 and a glass curtain wall system. The architectural precast contains two integral colors, stone liner and multiple lines of reveal work. There are two primary spandrel profiles with the lower spandrel utilizing the system’s darker tan stone liner and an acid etch finish. The second, third and roofline spandrels are two-tone with darker tan and lighter buff concrete. These panels also show dramatic relief with multiple reveals. In this structure, the columns are manufactured in different colors and are stacked together in the field. Each single color column features multiple horizontal reveals that return to the window elements and are finely finished with an acid etch wash.
There are many inherent advantages of a system with this number of inter-related parts. The most significant advantage is the coordination of all components expertly managed under one subcontracted trade. Stresscon engineered and sealed its own delegated design for the building system and each of the prestressed/precast components.
Stresscon also completed the manufacturing in their 70-acre facility and was responsible for the final installation and finishing of all of their precast/prestressed components that make up the superstructure. These structures reduce trade coordination, shorten construction schedules and minimize risk for all parties involved. |
