Bay Bridge W2 Pier Cap Oakland, CA
1:4.5 scale 52" x 42" x 80"

As you might have noticed, both the footing and the pier cap were made at an odd scale. The goal was to make the models as big as possible while still accommodating transport through standard doorways.  The engineering solutions that worked on the footing contract had to be shown to work at the pier cap—where the roadway meets the top of the pier.  The purpose of this was to minimize conflict and added costs on those contracts, as well.

These models were made of colored PVC rod, ground to precise and varying diameters with each color representing a different diameter.  We were excited that our technical and assembly solutions for the design and construction of the models worked out!
