ThyssenKrupp's MULTI elevator test tower is happening, indeed — and at a seemingly impressive rate. Less than 10 months after starting construction, the currently 232-meter structure in the German city of Rottweil recently celebrated its topping out. ThyssenKrupp is aiming to have the tower fully built and go into operation by the end of 2016. Once complete, the company will begin testing the first units of their cable-free MULTI elevator system, which they unveiled late last year.

ThyssenKrupp credits the tower's smooth construction progress through the use of "an innovative slipforming technique — all on time and on budget", and they obviously won't be slowing down anytime soon. The final glass story and the top of the elevator shafts will be added to the tower over the next two weeks, bringing the structure up to 244 meters. The tower will then reach its 246 height when the facade is complete.

Interior work for the tower is scheduled for mid-August. Building services and elevator equipment will be installed in the fall, and work on the outer skin is set to start on March 2016. In addition to the MULTI elevator system, the tower will be used as an innovation research and development site for new elevator technologies and mobility solutions for the future.
