Tympanum at the First Bank of The United States


This is a low res model derived from a super dense point cloud that captures the existing conditions of this beautiful wood carving from 1795. The building currently houses offices for The National Park Service in Philadelphia’s Old City.

Aaslestad Preservation Consulting is providing project architects  Mills + Schnoering with existing conditions documentation that will be “in hand” when the team goes up to do hands-on preservation/conservation work later this month.

Last winter I enjoyed collaborating with Draper Aden Associates on a project at Virginia Union University in Richmond. below is a video fly through of the model I made for that project. Above is a snap shot of me at work.

Guastavino’s St. Lawrence Basilica in Asheville, NC

…sharing a video clip fly through of this point cloud prepared from photogrammetry and a total station. The set of drawings that I’ll extract from this should be very interesting, more to come!

Below is a snapshot of the point clouds with the rendering resolution adjusted in order to distinguish the context point cloud to the area of inquiry, the bell tower roof.
