Investigating Limestone

CHICAGO, IL – Simpson Gumpertz & Heger (SGH) was out this week at the Shrine investigating the condition of the limestone on the interior face of the West Pediment Wall. The brick below the limestone needs to be removed to install steel plates for the new steel to tie back into the existing building structure. The brick condition at this location is poor due to being open to the weather for two season. More brick was removed than anticipated. The removal of the brick compromised the stability of the limestone. SGH was on site to make recommendations and construction continues to get ready for the steel delivery in January.
