When one of the largest malls in the world ran into trouble during an expansion, its team called in Keith Mittl. The $100-million project had come to a halt after developers became concerned about inconsistencies in their sewer plans, and they couldn’t move forward until they were confident of the system’s layout. Keith arrived, camera and equipment on hand, and he quickly identified major errors in the existing blueprints. The variations were so significant that many doubted his report, but Keith stood by his work. Upon further inspection, the mall’s developers confirmed that the sewer layout was indeed different than the available plans. Keith—and his MyTana equipment—were spot on.
