## What happens when plastic geometry meets material reality?

Fidelity of digital space and real space are often misaligned. In practice, these discrepancies lead to project setbacks and design failures. Constructive Collisions is a set of fifteen studies, exploring the productive friction between infinitely precise geometry, and real physical and spatial constraints of material and joinery tolerances.

Premise Diagram: Tectonic System X Surface Geometry

The research premise begins with a generative design matrix. Three typical families of tectonic systems are selected: Membranes (monolithic continuous surfaces), Plates (discrete surfaces), and Sticks (linear members). Five typical families of surfaces are selected, Ruled, Toroidal, Spherical, Conic, and Cylindric. For each surface geometry, a specific instance is selected as a control variable (ex: the Conoid as an instance of ruled surface. Over the course of two months, we designed and prototyped parametric schemes for each square in the matrix.

Each physical study fits within a bounding box of approximately 8” x 8” x 8”. Through these investigations, we realize that there is an inextricable link between the labor of design and the labor of execution. The architect has agency to take a stance with their design decision-making. They can select more harmonious resolutions of geometry and material to ease the difficulties of construction, or lean into the discord to produce new generative outcomes from standard systems.
