Refurbishing
The Tabernacle was closed from January 2005 to March 2007 for seismic retrofitting and extensive renovations. The baptistry, which was located in the lower portion at the rear of the Tabernacle, was removed as part of the renovation. New gold leafing was applied to the visible organ pipes, the ceiling was repaired and repainted, new dressing rooms and a music library for choir members were created, as well as three recording studios built underneath the main floor, the rostrum was remodeled to accommodate a secondary seating arrangement or a stage for performances, and all plumbing was replaced. The historic building was reopened in March 2007, and rededicated for use on March 31, 2007. An opening gala concert with the Tabernacle Choir was held on April 6–7, 2007.
All 44 piers that support the Tabernacle's unique roof were reinforced with steel bars, which were inserted into the piers from the bottom. The foundation of each pier was also reinforced with concrete. Steel boxes were used to connect trusses, and were also attached to the piers, clinched tight with structured steel.
