Seismic Upgrade for Federal Office Building Veneer

Los Angeles, Los Angeles County, 
California, USA

The seismic upgrade of a contemporary office building in downtown Los Angeles called on our’ technical expertise in selective masonry removal to be utilized in the salvage and later reinstallation of over 1,200 panels of 1 1/4″ thick Danby marble, with losses of original marble panels limited to under 2% of the total material. 

The marble panel restoration required the use of a diamond chain saw to selectively salvage the panels. Repairs and dutchman patching of anchor holes were carried out on site in preparation for later reinstallation. Epoxy-fabric seismic treatment (FRP) was applied to each previously exposed column. Use of this system instead of thicker cocrete or shotcrete allowed us to put each panel back in the original plane of installation.
