ZHA-designed Leeza SOHO is OEM's first collaboration with developer.
Leeza SOHO in Lize Financial Business District, a new commercial area in the Fengtai District, opened its doors for business on November 19, 2019, instantly becoming another Beijing landmark. Hitachi Elevator provided the vertical-transportation equipment, including 16 4-6 m/s double-cab elevators. The project is the elevator maker's first collaboration with developer SOHO China Ltd.
Leeza SOHO, designed by the late architect Zaha Hadid, has been called one of the most beautiful buildings in the world and has been described online as the futuristic building most closely matching the "cyberpunk" aesthetic for its ultramodern design. Offering 175,000 m2 of floor space, the building's 11,000-m2 footprint rises 45 stories above ground and four below. It meets the highest Class-A office standards.
Zaha Hadid Architects (ZHA) observed:
"Leeza SOHO's site is diagonally dissected by an underground subway service tunnel. Straddling this tunnel, the tower's design divides its volume into two halves enclosed by a single façade shell. The emerging space between these two halves extends the full height of the tower, creating the world's tallest atrium at 194.15 m, which rotates through the building as it rises to realign the upper floors with Lize Road to the north. This rotation of the atrium intertwines Leeza SOHO's two halves in a dynamic pas de deux with connecting skybridges on levels 13, 24, 35 and 45. Its glazed façade gives panoramic views across the city. Leeza SOHO's atrium acts as a public square for the new business district, linking all spaces within the tower and providing varying views due to its twisting, sculptural form."
Besides access to the high-speed, double-cab elevators, every office is equipped with a 5G network and a ventilation system with automated filtering. The project achieved Leadership in Energy and Environmental Design Gold certification.
The building's steel structure weighs 18,300 mT, equivalent to 2.5 Eiffel Towers. As a 679-ft-tall edifice with a special structure, the project faced unusual challenges, in addition to meeting Beijing's strict construction standards. In view of the quantity and weight of the elevator components, Hitachi Elevator first worked out a detailed plan with the general contractor on how to coordinate the logistics so 630 boxes of components could be efficiently transported for installation. The plan proved effective.
The work required precise positioning of the double-cab elevators, and assembly of their large-tonnage main bodies and the debugging of their circuitry. All this was completed on schedule during the final stage of construction. . .. Wang Youchen, one of Hitachi Elevator's Leeza SOHO project managers, was praised as a key contributor to the successful completion of the project.
Beyond the collaboration, Leeza SOHO, Hitachi Elevator and SOHO China are jointly engaged in the promotion of public education. Toward this effort, Hitachi Elevator donated an elevator to a school supported by SOHO, Yangzheng Kindergarten in Tianshui, China. Delivery and installation were scheduled for completion in December 2019.
