Tulsa's World Publishing closes its Excalibur Building from quake damage
The November 2011 earthquake likely caused the structural damage that led Wednesday to the closing of a downtown building.
The November 2011 earthquake likely caused the structural damage that led Wednesday to the closing of a downtown building.
That finding was included in an engineer's report received Monday by World Publishing Co., the building's owner.
World Publishing President John Bair said a consulting engineer was hired to evaluate the building after exterior masonry and precast concrete fell from the Excalibur Building - also known as the Main Mall Building - at 324 S. Main St. in late August.
The engineer, William Dashiell of Norfolk, Va., wrote in his report that the building showed damage that "is not the result of excessive floor loading, wind ... or water damage. It is the result of a sudden lateral seismic force."
