As recently as the 2000s design and construction documentation were developed in two-dimensional drawings. On complicated projects such as the Arizona Science Center in Phoenix, it was difficult to convey the award-winning designer’s vision through 2D documentation and to analyze constructability and connection geometry and details. The designer was renowned for bringing nature into architecture with his use of raw materials and non-standard geometric forms. The project was comprised of multiple exposed cast in place concrete structures with complex shapes, angles, intersections and tolerances tied together by a metal wedge (peak) running through the middle. The project required over 12,000 cubic yards of 4,000 psi concrete and more than 1,100 tons of reinforcing steel.

 

When Sundt realized there was no way to construct the building using conventional forming systems, we brought brand new 3D computer modeling technology to the table (more than 10 years before Building Information Modeling became popular). The technology allowed us to build the project on the computer before starting the actual construction. In addition, it identified constructability issues and design flaws. Concrete formwork generated in 3D allowed for tight joints and form lines that met the design intent.

 

The team extracted point data from the 3D model for input into robotic total stations for formwork layout, and extracted volume from the 3D model to generate concrete volume and steel component weights. Animating the 3D model allowed the team to show and analyze the sequencing of the concrete pour.
