Abstract: The Leeza Soho skyscraper designed by Zaha Hadid Architects is under construction in Beijing’s Lize Financial Business District. The building will be 207 meters tall, with 46 floors destined for a variety of different uses, and will be the skyscraper with the world’s highest foyer, 190 meters tall. This unusual feature, a foyer almost as tall as the building itself, is due to the features of the site on which the construction stands: the area is divided in two diagonally by the new metro tunnel, and below it is the new exchange between lines 14 and 16 of the Beijing metro. The skyscraper will look like a single volume, but its construction will actually be divided into two halves built on either side of the tunnel, connected by the central foyer. In its vertical development, the Leeza Soho undergoes a slight twist, returning to the east-west alignment of the Lize Road, an important traffic artery in Beijing, on the top floors. The twist is underlined by the public square surrounding the building and receiving visitors and reflected in a different façade solution in the central part of the skyscraper. The big clear windows ensure that all the building’s floors have panoramic views of the city and that daylight penetrates right to the Centre of the building.

Soho China SOHO China is a Chinese office developer. The company was founded in 1995 by Chairman Pan Shiyi (潘石屹) and CEO Zhang Xin (张欣). SOHO China focuses on developing properties in the central business districts of Beijing and Shanghai. SOHO China developments are known for their modern architecture, with designs from architects such as Zaha Hadid and Japanese architect Kengo Kuma. The company has developed over five million square meters of commercial properties. The company uses the name "SOHO" in both English and Chinese contexts. SOHO China is China's only pure prime office developer. Having shifted from a “build to sell” to “build to hold” strategy in 2012. the company now holds 1.4 million square meters of office space in Beijing and Shanghai for longterm investment.

Architect

Zaha Hadid, the Iraqi-born British architect who was the first woman to win the Pritzker Architecture Prize and was recently awarded RIBA's 2016 Royal Gold Medal, died from a heart attack today at the age of 65. Per a statement from Zaha Hadid Architects on the shocking and saddening news, "Dame Zaha Hadid, DBE died suddenly in Miami in the early hours of this morning. She had contracted bronchitis earlier this week and suffered a sudden heart attack while being treated in hospital." Born in Baghdad in 1950, she studied mathematics at the American University of Beirut and then headed to London in 1972 to study architecture at the Architectural Association. She established her own architectural practice there in 1979 and four years later came to international attention with the competition-winning The Peak in Hong Kong. Most early projects, like The Peak, remained unbuilt, but eventually Hadid became one of most renowned and prolific architects this century, especially in the years following the receipt of the 2004 Pritzker Prize. Alongside office partner Patrik Schumacher, she designed and realized what the firm describes as "unexpected and dynamic architectural forms" all around the world.

Notable completed buildings include the Vitra Fire Station in Weil Am Rhein, Germany (1993); the Hoenheim-Nord Terminus and Car Park in Strasbourg, France (2001, the recipient of the 2003 EU Mies Award); the Rosenthal Center for Contemporary Art in Cincinnati (2003); the MAXXI: Italian National Museum of 21st Century Arts in Rome (2009, recipient of the 2010 RIBA Stirling Prize); the Guangzhou Opera House in China (2010); and the Heydar Aliyev Centre in Baku (2013). The Li Ze tower is the latest of four projects that Zaha Hadid Architects has designed for the developer Soho China, including two others in Beijing. The Galaxy Soho building is made up of four main domed structures, while the Wangjing Soho commercial complex features three pebble-shaped towers located midway between Beijing Capital Airport and the city.

Concept location As an entry point to a bustling financial district, elegantly twisting on top of a subway tunnel, Leeza Soho is a representation of the connected, innovative, and fast-paced society. In addition to our photorealistic night interpretation of the future building, our mission was to emphasize the nocturnal effects of the actual facade, interior, and landscape lighting in sync with the tower’s dynamic context. We visualized the tower’s transparent facade, reflecting its surroundings, and at the same time accentuated its silhouette through eye-catching uplights (spiral floodlight), emphasized by the interior, top and other lighting elements. Undoubtedly, Leeza Soho’s abstract twisting atrium was its most prominent feature, so the significance of its lighting representation was key to the final holistic 3d visualization of the tower.

Architecture side Construction is well underway on a 207-metre skyscraper by Zaha Hadid Architects in Beijing, which will feature a huge twisting atrium that is expected to be the world’s tallest. Located in the Lize Financial Business District – a new business, residential and transport hub in southwest Beijing – the 46-storey Leeza Soho will feature a mix of offices and shops. Designed by Zaha Hadid before her death last year, the skyscraper – which is already 20 stories tall – is positioned above a pair of subway lines that diagonally divide the site.

The tower is split into two halves by the subway and connected by a huge central atrium. As it rises, the atrium twists at 45 degrees to orientate the higher floors with the east-west axis of Lize Road – one of west Beijing’s main streets. Once completed, the 190metre-high void is expected to be world’s highest – a title currently held by the Burj Al Arab hotel in Dubai.

The shape of the atrium creates convex openings that run up either side of the tower to allow for plenty of natural light and views of the city from the centre of each floor. Walkways will bridge the cavity at different levels, while a glass facade will encase the two halves of the tower in a single cohesive envelope. The glazing will be double insulated and as each glass each pane steps up it is angled to aid ventilation. The intention is to help maintain a comfortable indoor climate in Beijing’s weather conditions, which ranges from extremes of warmth and cold. A public space connecting with the interchange below will occupy the atrium on the lowest level, leading on from the outdoor public plaza that surrounds the tower. There will also be space to park 2,680 bicycles, with lockers and shower facilities also provided. Dedicated charging spaces for electric or hybrid cars are located below ground. Construction of Leeza Soho is to reach its full height of 207 metres in September this year, with the tower’s completion slated for late 2018. The tower is the latest of four projects that Zaha Hadid Architects has designed for the developer Soho China, including two others in Beijing. The Galaxy Soho building is made up of four main domed structures, while the Wangjing Soho commercial complex features three pebble-shaped towers located midway between Beijing Capital Airport and the city.

A SUSTAINABLE VOID Leeza SOHO is targeting LEED Gold environmental certification and the atrium plays a key role within the tower’s sustainability strategy. As the building rises, its diagonal axis is twisted through 45 degrees to orientate the atrium’s higher floors with Beijing’s historic north-south axis. This twist not only creates views from the centre on all levels, but also allows natural light to penetrate deep into the building’s floorplate. Above: The atrium plays an important role in the buildings environmental strategy Additionally, the tower contains a range of sustainable technologies with an advanced energy management system monitoring real-time environmental control and energy efficiency within the structure. There’s also highefficiency fans, chillers, boilers and lighting and a water-collection system that re-uses grey water in toilet flushing and landscape irrigation. Internally Low Volatile Organic Compound (VOC) materials have be installed throughout the tower to minimise interior pollutants, and in the basement there are 2,680 bicycle parking spaces together with dedicated charging spots for electric and hybrid cars.

Construction side

The structural system of Leeza Soho is a combination of concrete and steel. “Reinforced concrete has sculptural qualities; it was therefore the ideal choice to realize curvilinear form of the tower,” Satoshi Ohashi, project director of Zaha Hadid Architects, tells Construction+. “On the other hand, wide-flange steel had long-spanning qualities; it was therefore selected to realise the inter-connecting bridge. This combination enabled Leeza Soho to realize the fluid, dynamic forms, while maintaining construction and economic feasibilities.” Each of the two halves of Leeza Soho have their own structural core and perimeter columns that follow the curvilinear exterior form of the tower, with steel tension rings surrounding each floor plate. The four aerial bridges that connect the towers are made of wide-flange steel beams and columns, which provide the right strength to resist bending stress and enabled the bridges to span extended distances.

THE CASE FOR ALUMINIUM “Of all the components that make up Leeza Soho, its façade is arguably the most visually significant,” says Satoshi. “While the building’s structure keeps it standing and MEP ensures its daily functioning, the tower’s façade envelops all components together in a fluid, cohesive whole.” The design team, therefore, committed great effort to the research and development of the façade. The first challenge was to find the most suitable material. The design team initially rationalised the digital 3D model of the building by dividing the overall shape into individual panels with reasonable dimensions. They then optimised the different panels using an algorithm that searches for shape similarities within the façade to a tolerable degree—minimising the number of different façade panels required, preserving the original curvature quality of the design, while maintain an acceptable level of fabrication and economic feasibility. During the first round of façade mock-up exercise, different fabricators were invited to build façade mock-ups with different cladding materials— aluminium, form steel, glass-reinforced concrete (GRC), and fibre-reinforced polymer (FRP). These mock-ups were tested based on their material’s ability to express smooth curvilinear geometry, maintain clean edges, and preserve accuracy that is faithful to the original design model.

While FRP, GRC and form steel were all capable of maintaining the characteristics of the original 3D design, only aluminium could deliver the building within reasonable time frame, effort, and budget. The material is durable, and the technology is well established in China. Thus, Leeza Soho became an aluminium-clad building.

The structural system

LEEZA SOHO is a complicated connected twin-tower structure. The plan of a single tower is spiral-up layout on the atrium side. The single tower is an arc-shaped frame-core wall structural system. There are four ellipse rings made of bridges and middle trusses between the two towers. The four rings make the two towers become an entire structure. The structure is composed of two complecated dissymmetry towers, which are connected by steel bridges of 9-38 m long. The structure is 191.5 m high. The three structural concepts are compared. One is a 'resistance' concept by the braces on the faç ade of the single tower. The second concept is 'dredge'. Some columns are used to support the gravity of the suspended structure directly. The third concept is 'hoop'. Bridges and waist trusses are set between the two towers like hoops. These hoops will make the two towers become an entire structure. The strucutre will have a good seismic performance. The effects of the connection between the two towers are introduced. The adopted structural system and the calculation results are summarized, which can provide usefule reference to similar seismic design of complicated super tall buildings beyond code limit.

QUALITY AND ACCURACY In the second round of mock-ups, various well-established façade companies from all over China were invited to deliver mock-ups made of aluminium panels with the best overall geometric accuracy and installation quality. The design team was also looking for the best connection bracket and transfer bracket details, for accurate installation and easy adjustments. Each individual panels are given individual bar code identification to assist with on-site tracking. The designs are created digitally using 3D building information modelling and sent directly to the fabricator. From the first panel to the last, the digital information of every single panel is tracked from the factory for quality and accuracy purposes.
