Our Role

Supporting DEAL, McNary Bergeron & Johannesen oversaw segment handling and segment erection analyses of the cores. We performed a vertical construction analysis of the building cores to evaluate construction stresses and estimate lateral deflections due to PT stressing operations. MBJ also performed analyses of the segments during shipping, handling, and installation as well as performing checks of the DEAL designed segment handling equipment.
