Cathedral of the Immaculate Conception
Albany, NY

Constructed between 1848 and 1892, the Cathedral is a National Historic Landmark and the second Roman Catholic Cathedral built in NY State. 

We provided structural engineering services for the project which included the exterior masonry restoration and interior renovations.

The Cathedral’s existing vertically bedded brownstone had extensively delaminated and failed primarily from freeze-thaw cycles. The exterior restoration included replacement of the brownstone for 60 percent of the building including the 190-foot-high north tower.  At the time, it was considered the largest brownstone restoration project in the Western Hemisphere.

Let us provide the benefit of our extensive experience in a timeframe that meets your needs.

Our scope included:  in-situ testing of proposed stone anchors; analysis of the structure under construction loading; design of scaffolding support, and design of the north tower steeple reinforcing and hold-down, post-tensioned cables.  The interior renovation included reconfiguration of the altar, restoration of the neo-gothic plaster, and structural improvements of the floors.  All of this work was coordinated around a crypt located beneath the Cathedral which houses the coffins of six former Bishops.

The project won a Gold Award from the American Council of Engineering Companies of New York and the Outstanding Engineering Achievement Award from the New York State Society of Professional Engineers.
