Joe Mugford presented lessons learned from the column transfers designed by GMS for 75 Rockefeller Plaza at the 52nd annual convention of the Structural Engineers Association of Arizona (SEAoA). The top-to-bottom overhaul of this landmark, built in 1947 includes new double-height glazing and upgraded entry. A reconfigured lobby required the transfer of four existing building columns. 

The SEAoA encourages practice in accordance with the highest ethical and professional standards by providing continuing education through regularly scheduled technical meetings and seminars. Members exchange knowledge and experience, participate in local as well as national code development and advisory processes and pursue issues affecting public safety.
