Inverted Collar & Tie
Project
Inverted Collar and Tie by Claes Oldenburg and Coosje van Bruggen is located in the heart of Germany's financial district on Platz der Republik. This is the first of 15 large-scale projects fabricated by Kreysler & Associates for artists using fiberglass-reinforced polymer combined with finite element analysis engineering. The sculpture was fabricated using 3D laser scan data of the artist’s maquette. The data was scaled in the computer to approximately 40 feet and cut into 1-inch slices or “cross sections”. Each “cross-section” slice was then cut out of foam on a 2-axis CNC router and stacked to create the full-size part. Glass fiber was then applied over the foam to create a structural shape. The surface was faired, sandblasted, and coated with marine-grade polyester gelcoat. The sculpture was fabricated in one piece and shipped as deck cargo from Oakland, California to the port of Rotterdam then taken by river barge to Frankfurt, Germany. Although there is a structural steel frame at the base hidden inside the collar, the remainder of the sculpture is engineered using finite element analysis and therefore is self-supporting.
