The Center Building, a local landmark in Napa’s historic district, is a two-story brick and masonry building designed by famed local architect William Corlett in 1905.

Due to extensive structural damage following the South Napa Earthquake in August of 2014, this building was one of several that were under threat of demolition.

In order to repair and seismically upgrade the historic facade, the original masonry stones needed to be removed.  The local Cultural Heritage Commission was concerned the historic integrity of the facade would be compromised and was against the removal until the architect was able to convince the Commission the facade’s appearance would be restored to mimic the original using scanning technology for the 2D as-built survey.

Having scanned the building exterior facade with a 3D laser scanner, we were able to create a precise 2D CAD drawing of the elevation.  The masonry stones were labeled and a legend was created prior to removal to ensure accurate replacement. Each stone can be measured from the scaled drawing.
