Situation
The assignment was to design a parking structure to support the expanding Children's Hospital. The objective was a structure that would invite children and make them feel like the hospital was approachable. This was a true Design/Build project. The design called for pre-topped double tees, beams, columns, non-bearing and load-bearing spandrels, light shear walls, stairs and Spancrete® hollowcore plank.
Challenge
An extremely tight construction schedule and spandrels with unique architectural detail provided a dual challenge, as the owner had very exact specifications and expectations for the look of the structure. The builder could only erect one portion of the building at a time, moving east to west in the process. They erected the complete east section, the entire center ramp section and then the west portion of the complex. The jobsite had extremely tight confines as numerous other construction projects were occurring simultaneously.
Solution
AXIM admixtures and SCC Technology assured the project adhered to the tight construction schedule. The structure was completed on time due to constant communication of project status and a high level of trust among the partners. The end result is a beautiful architectural building for the hospital.
Highlights
This nine-level, 530,000 square foot parking structure utilizes architectural and structural Self-Consolidating Concrete (SCC). It accommodates 1,600 cars and includes a sky walk to the hospital. The buff-colored concrete exterior has an acid etched finish on panels with reveals and bullnose accents. |
