New Capitals for 250 Delaware Avenue Combine Old and New Fabrication Techniques

Making components such as the pier capitals on the facade of the old Delaware Court Building shows the combination of old and new techniques involved in making highly detailed ornamental pieces. These, and many other intricate components involved in the replication of units for 250 Delaware Avenue have to be carefully and precisely detailed.

A point cloud scan of the facade (left) is used to extract a 3D model of the component (center) and then used to fabricate a final piece (right)

The process begins with taking a scan of the facade and then using that to make a CNC base file which will be used to create the plaster model and eventually, the mold.

It is apparent from the image the creation of the exact historic piece is twofold: the precise geometry is created by machine, and the handcrafted detail is added by skilled artisans. The plaster model is milled and additional clay is then sculpted onto this plaster base by the artists in the shop.
