For this project We were required to build a metallic structure designed to connect two buildings and to act as a motor lobby for the complex, the main spine was a 70 meters long, continuous curve, fabricated in 500 pieces of strategically cut steel tubes ranging from 10” to 2” diameter. These were manufactured off-site in our workshop, where we gave them the curvature needed to fulfill the project’s geometry, as well as the pipe fitting needed to create smooth connections.

Given the complexity of the connections between the tubes that form the structure, a custom script was developed to automatize the extraction of fabrication documentation; the script takes as inputs the curves that represented the elements of the structure, and automatically generates not only the volumetric model, but also allows us to extract the cutting profiles necessary to facilitate the assembly of each piece with its intersecting complements. Each piece had to be cut with a particular profile in order to allow a proper assembly in its assigned place, so one of the script´s outputs was an unrolled plane of each intersection that could be printed and rolled around the tubes as a template to proceed to the cutting process.

The structure required not only to cut the tubes, but also to bend them, to form the curved profiles described in the design given the length of the main curves, the script had to be extended to rationalize the curves into smaller pieces that would allow us to fabricate them from standard length material. The design was composed of free form curves, which could not be redrawn as arc segments without considerably altering the original trace. In order to maintain the desired form and to be able to bend and rectify the curvature in the tubes, we extracted from the model a series of coordinates that then could be plotted in our workshop and that would allow us to draw all the curves in a 1:1 scale. Those strokes were used as a guide for a pre-assembly of the structure that took place off-site, and then was sectioned into pieces that could be transported to site for the final installation.
