OMA: the shenzhen stock exchange nearing completion

on a recent trip to shenzhen, china, designboom toured the construction site of the shenzhen stock exchange by
rotterdam-based practice OMA. the tower is located along shennon road, a defining axis through the linear city
between the civic center, commercial heart and residential district. an elevated podium becomes a dominant visual element,
intended to broadcast the activities occurring within the floating box to the city. as neighboring buildings continue
to emerge, the exchange continues to become connected into the developing

cantilevering 36 meters from the edge of the atrium's outer structure, the rectangular volume is supported by external diagonal
mega-bracing while hollowed wide flanges are solely to contain the glass curtain wall. as the scaffolding near the base
has been recently removed, the extensions have revealed framed outward views of the city. along the south end of the building,
a stepped ceremonial south plaza will welcome important figures into the exchange with water and vegetation. the glass of the
facade is pulled away from the structural elements to render a consistent exterior regardless of the conditions behind the vision panel.
at night, the translucent glass will project a soft glow into the urbanscape.

two grand atriums are placed at the ground level, a primary entry on the east and lobby for main rental floors on the west.
overhead, voids within each of the podium's 15,000 square meter floor plates allow natural light to illuminate the atrium below
while also distinguishing the tower and base as separate entities. on the 8th level is the public floor containing a conference center
with stepped seating for lectures and events. within the other half of the podium is the traditional trading floor which will be used
to ceremoniously ring the bell for a new company as trading is now done digitally. balconies wrap the podium overlooking the
developing urban context.

within the tower, executive offices are directly above the podium overlooking an ornate roof garden evoking a chinese
paper-cut pattern. leaseable offices are found within the upper portion of the tower. mechanical and support spaces are concealed
within lower levels below the 8th floor.

the patterned glass skin of the tower facade provides a simple but highly effective system for shading the transparent vision-panes from
the hot sub-tropical sun and negating the need for any additional complex and expensive exterior shading.
direct ventilation is provided by panels concealed behind the structural elements in the facade, allowing for the pure expression of the grid to remain.

the facade of the lifted podium also uses the same textured glass as the tower cladding but, is held in contrast through its differing use of scale,
articulation, and layering. the glass is used to create subtle optical distortions in the facade, its depth also allows for the creation of a balcony
between patterned glass and recessed vision glass.

the raised podium is approximately 160mx100m in plan and has a maximum cantilever of 37m and a structural depth of approximately 24m.
there are 3 primary floors as well as one partial mezzanine floor and an accessible landscaped roof.
the podium is fully connected to the tower structure, and has a 3D structural system consisting of primary and secondary planar steel trusses,
and diaphragms at roof and soffit levels.
podium gravity loads are primarily carried by four vertical primary columns and four inclined primary columns, all located at the root of the cantilever.
gravity loads from zones adjacent to the tower are carried by the tower perimeter frame columns.

'for millennia, the solid building stands on a solid base; it is an image that has survived modernity.
typically, the base anchors a structure and connects it emphatically to the ground. the essence of the stock market is speculation:
it is based on capital, not gravity. In the case of shenzhen’s almost virtual stock market, the role of symbolism exceeds that of the program –
it is a building that has to represent the stock market, more than physically accommodate it. it is not a trading arena with offices,
but an office with virtual organs that suggest and illustrate the process of the market.'

--
the 2011 SZHK biennale
in shenzhen, china runs from december 8th through december 11th 2011.
the scale of certain projects is such that the architect becomes not only a designer of buildings but also city planner and landscape
architect and the the shenzhen & hong kong bi-city biennale of urbanism \ architecture reflects this in its theme:
architecture creates cities - cities create architecture.
the SZHK biennale is the first to focus on urbanism as an ongoing theme to explore issues of the city as an active agent in contemporary culture.
the program includes more than 30 exhibitions, symposiums, panel discussions and performances.
terence riley has been appointed chief curator (he is the first international curator for the event).
the hong kong edition will work to complement the shenzhen biennale in an integrative way and is curated by gene king and
anderson lee currently under preparation and due to open in february 2012.
designboom is the principal international media partner of the SZHK biennale.

'shenzhen builds'
designboom was given the opportunity to visit the construction site of the terminal extension, as part of the program 'shenzhen builds'.
the buildings being built in shenzhen today are setting international standards for most of the building types:
the 'shenzhen builds' exhibition, curated by terence riley, focuses on 5 new and upcoming buildings in the city by coop himmelb(l)au / wolf prix,
massimiliano and doriana fuksas, OMA / rem koolhaas, urbanus, and atelier FCJZ / yung ho chang.
on show are models, animations and drawings, including other developmental materials to demonstrate how these projects were conceived.
designboom will cover this exhibition in upcoming articles, please stay tuned for more to come.
