Laser Tracking Metrology: An Integrated Fabrication Process for Geometrically Complex Facade Systems

The geometric complexity resulting from the architectural pursuit of freeform structures is presenting challenges to the construction industry. Curtain wall unit system designs, for example, have morphed in some cases from predominantly flat orthogonal affairs to complex double-curvature multi-laye...
