With a height of 159 m and 47 floors, the Westend Gate in Frankfurt, Germany, is an unmistakable part of the city’s skyline. Built in 1976, the high rise was modernized by KONE between September 2015 and January 2017. Our team had to schedule several hours of intensive onsite work, while taking care not to disturb the many people staying and working within the complex, especially the Marriott Hotel, which has been the main tenant of the building since 1989. Often, meetings were held in the building’s courtyard to not disturb the hotel guests, and noise from the construction was kept to minimal levels.

Developer RFR Management wanted to make building transportation smooth and seamless. To minimize time and save resources, we began by improving ease of access to the building by refurbishing its doors and improving its secure entrance. Our KONE Access™ access-control system was integrated with the building elevators to improve security and efficiency. Our elevators were also equipped with advanced technology to conserve energy. While the old elevator drives had an estimated power consumption of 35 kWh, the new elevators use only 7.5 kWh. This and other energy-saving solutions played a role in getting European Union Green Building Certification for the building.

Drees & Sommer provided general construction management, Rudi Becker served as lift planner, and Dörflinger Elektrotechnik performed electrical engineering on the project.
