Precast Concrete Façade | Perot Museum of Nature & Science by Morphosis

Perot Museum of Nature & Science by Morphosis
Dallas, Texas; 2008-2013

The example of the new Perot Museum of Nature & Science is particularly interesting in terms of latest technologies because this project is characterized by an extensive use of computer aided modelling (BIM) which did not only help the architect during the design phases but also the whole coordination that was needed in later structural calculations and construction. The use of this technology is especially noticeable in the pre-cast concrete façade, which is designed to resemble geological formation. The skin is made of 700 elements with the same overall size but with a varying texture. In order for the façade to be developed with a continuous texture between the modules, a mold system of 39 geometry families (both recessed and protruding) was studied, creating a series of 4 panel shapes in 12 patterns. The 39 mold pieces were each time assembled in different combinations, in order to cast a new panel. This systematic and computerized technique guaranteed a customized façade, delivered on time and within the budget. The concrete panels are load-bearing and fixed to the metal structure of the building.

Here there is a time-lapse of the overall construction:
