Bay Area landscape studios team with local artisans to evolve CNC-fabricated site elements.

Alcatraz keeps disappearing, but not because of sea-level rise. “Alcatraz Island has been stolen, replaced, and stolen again,” says Nicholas Gotthardt, a senior associate at Surfacedesign in San Francisco. The irresistible Alcatraz is one element of a large topographic model of San Francisco’s Golden Gate headlands that anchors the visitor overlook at Fort Point National Historic Site, where Surfacedesign was part of a team that designed new site amenities completed in 2014.

The model, made of finely detailed precast concrete, is a literal touchstone at the overlook, which offers dramatic views to the Golden Gate Bridge and San Francisco Bay, as well as a rest stop for cyclists and hikers. Gotthardt recalls the impetus for creating the model: “We wanted to design an interpretive piece that wasn’t signage and words. We wanted something tactile—something people could touch.” Gotthardt had honed his digital modeling skills in the fabrication lab at the Ohio State University’s Master of Landscape Architecture program. With the Fort Point project, he found an opportunity to apply those skills, including fabrication using computer numerical control, or CNC, at the site scale. “The idea of a pancake topo model as the centerpiece of this small urban space came from the officewide comment that ‘We should build more models!’ There isn’t always the time or resources in practice to get into physical modeling the same way that you get to do in school.”

Today both undergraduate and graduate landscape programs provide training and facilities in CNC fabrication, including five-axis mills for sculpting wood and foam, 3-D printers, and laser cutters. Yet this new generation of graduates, facile with the work flow producing CNC models in the design studio, often finds it difficult to ply these skills once they reach (more…)
