ATLANTA — “We are in a revolution. The public simply can’t afford to pay the price of construction in its current form. This is the time to take BIM, 3D, pre-fabrication and industrialization and change this industry that is absolutely in the dark ages.” With these words, Dr. Charles H. Thornton, P.E., former co-chairman of Thornton Tomasetti, opened the 2010 Tekla User Meeting for Tekla Structures users in Atlanta.
