That astonishing report came from our architect and general contractor who are overseeing the rebuilding of our 119-year-old Sanctuary. The entire western half of the structure, which has been undergoing seismic retrofitting since April 1, now has a steel-reinforced concrete foundation and steel columns holding up the oldest and most vulnerable portion of the building.

The shoring that we all see while walking to and from worship service has reinforced the roof while the old and crumbling rock and mortar foundation and old walls were removed. Dirt was taken out to allow massive new foundations in huge trenches to be built. Footings for the new steel columns were added at the same time.
Then the "surgical" work of bringing in and placing the massive steel columns and beams that form the two critical "moment frames" began. The work took just two days in early August but felt like years for the professionals who maneuvered the hundreds of pounds of custom-fabricated girders onto huge plates and then onto the tops of the beams.
Actively monitored welding -- to ensure there was no fire threat inside the Sanctuary -- connected the beams to the columns so that steel and concrete structural "units" were created that will safeguard the building when the next major earthquake strikes. These "moment frames" are now in place and support the western half of the building.
