  • National Treasure

    October 23, 2014 – Mid-century Modern buildings in the Petrified Forest National Park, whose structural restoration is being aided by MBJ engineers, were recently designated a national treasure by the National Trust for Historic Preservation. To preserve these iconic structures, MBJ’s engineers are designing structural remedial solutions for foundations, masonry load-bearing walls, and slab-on-grade structures. Originally designed by architects Richard Neutra and Robert Alexander, these buildings express the architectural aesthetic of an age when National Park tourism was at an all time high. Read about the history of these buildings here.
