unstable forms into a stable structure (Figure 5).

A tightly controlled environmental system to protect the works of art was required, and
that system would have special ductwork for various zones that would run from
centralized mechanical rooms to the galleries. Like the structural system, the ductwork
could not follow typical vertical and horizontal paths. All lateral loads are resisted by
latticelike steel bracing on the exterior walls; some additional bracing runs through the
interior. To avoid the angled walls from deflecting during the construction they had to be
shored. The challenge was to determine which geometry to use so that when the gravity
loads were imposed on the structure it would deflect to the desired architectural geometry
(CE 06, Dec).
Due to the severely inclined walls and large cantilevers, it was decided early on that the
