The large umbrella and Chapel Lomas de Cuernavaca were built with wood strips using a methodology that parallels Candela’s construction process
Large Umbrella Model (from Mercado de Chiclayo)
Undergraduate students Christin Holzer, Plamen Ivanov, Marianne Koch, and Kira Schiavello, and graduate students Sarah Halsey and Powell Draper began with a computer rendering of the structure. A frame that supports the edges of the shell was cut out of medium-density fiberboard (MDF) and slots were cut through the thickness to support 1/2 inch deep by 1/8 inch wide aluminum beams. These beams supported 1/32 inch thick plywood strips that were pressed against the beams with double-sided tape. Wood filler was pushed between the wood strips to give the same effect as concrete seeping through the form boards. Fiberglass fabric was placed over the top surface and wet with an epoxy. While the epoxy was still wet, a second layer of wood strips was placed orthogonal to the first layer. The surface was then lifted from the frame and connected to the column and foundation after which it was primed and painted. Jesse Hindle and Emily Roche used a mix of fairing filler and epoxy to create a smooth transition where gaps were visible under the ribs and edge beams.
