The membrane arrives, packaged strategically to be unfurled from the center point of the structure.
The aluminum extrusion is stripped from the edge beams, and threaded along the keder of the membrane along the long flat sections. Where the perimeter is more complex, the extrusion is left on the beams, and the membrane slid on.
The team slides the membrane keder down through the doubly curved edge beam.
The team uses long sections of threaded rod to tune the aluminum extrusion and the membrane inwards against the northern edge beam.
Feeding the membrane down through the doubly curved extrusion.
The team begins to install membrane, cut to shape and patterned to form around a series of ridges and valleys created through push ups and valley cables.
