Orchard Road shopping center, Singapore HDA: facades designer Client: RE Properties Pte Ltd Architect: Raymond Woo architects Raymond Woo architects selected HDA as specialist design consultants for the facades of a new development on Orchard Road for the RE properties Pte Ltd Ngee Ann City development company.. Orchard road is a vibrant shopping street, Singapore’s Champs Elysées. Architecture of recent buildings on the street strives to compete in the competitive commercial context, each building trying to be more remarkable than its predecessors. In response to a programme of shops and restaurants, HDA proposes an alternative concept of calm transparency. The tenant shops are clearly visible from the street and provide animation through all glass facades. Three successive glass boxes rise up one above the other, each one set back slightly from the other. The lowest one opens onto the street providing a central atrium for the building. The two higher ones provide restaurant spaces. The lateral facades are also clad in glass, providing transparency for the shopping facilities on all levels. The boxes are mode of a slender grid of stainless steel extruded profiles, braced with a 3D cable net system in the form of a tree. The 20m span roof members exploit the cable system for the required inertia. The facades are braced with a series of vertical cables and horizontal counter cables. This mesh of cables are prestressed by the cable tree to provide stiffness and stability against wind pressure. HDA developed a form-finding program to define the cable net geometry. The façade grids extend down to street level and curl outwards to form an entrance canopy. Glazing products are printed to a variable pattern and include roof-top grillage panels that provide additional solar protection as well as providing maintenance platforms. The lateral facades are in a double skin system using vertical glass fins. The double skin is equipped with roller blinds between the two glass surfaces to absorb solar energy.

Jiang Tai winter garden, Beijing, China HDA: envelope designer Client: Swire Properties in Joint Venture with Sino Ocean Land Architect: Benoy Swire Properties’ Jiang Tai development in Beijing consists of a shopping center and a 5 hectare park. HDA designed a 7000m² wintergarden that acts as a transitional zone between the shopping center and the park. The Wintergarden consists of a wavy gridshell mesh roof with a generous canopy creating a fluid gesture toward the park. The canopy edge rests on a line of slender vertical columns that carry a cable net facade maximising the transparent interface with the park. The roof mesh is a composition of triangular modules of glass panels, whose composition follows the same fluid movement of the roof wave toward the park. The glazing panels include sun treatment and louvers to create a soft light and shading patterns.

Taikoo Hui development, Guangzhou, China HDA: atria boxes, podium facades, canopies and interior footbridges designer Client: Swire Properties Ltd. Architect: Arquitectonica In Guangzhou, Swire Properties have recently completed a mixed used commercial development taking up a full city block and comprising hotels, offices, shops and a cultural center for the city. TaiKoo Hui is thus a large-scale multi-faceted complex in the thriving heart of the Tianhe Central Business District of Guangzhou. Offering a gross floor area of approximately 358,000m2, it incorporates a prime shopping mall, two Grade A office towers, a cultural center, the first Mandarin Oriental Hotel in Guangzhou, and serviced apartments. HDA were engaged by Swire Properties as specialist design consultants to architects Arquitectonica for all the feature glazing components of the development; notably the main entrance atria boxes, and waving linear skylight down the central spine of the shopping mall. HDA developed a unique concept using repetitive structural modules and steel profiles of triangular shape as support for the glass panels in order to bring a tactile identity of specific details while give an architectural coherence of the lot. HDA has conceived each glass element, including the preliminary structural analysis and the development of details. Daylight is a key ingredient to the shopping centre, and notably with the intent to flood the mall with light deep into the lower and basement levels. The glass components designed by HDA celebrate daylight, providing sculptural expression that responds to filtering light, and playing with shadows. Other fragments, such as the cultural centre lobby suspended glass footbridges, glass flooring and glass canopies, are carried out in a similar design approach based on simple geometric compositions that play with light. Waffle grids in the case of the entrance box atria and a curvilinear series of glass facets for the main skylight. For both, the simple surfaces are reinforced with tensile bracing systems that complete the design composition with points of interest or spatial geometric compositions. Careful attention is paid to the design of the assembly details and structural components.

Lyon Grand Bazar, Lyon, France
HDA: facade designer Client: Virgil Architects: Jean Pierre Buffi & Phillippe de Fouchier The architects Jean Pierre Buffi and Philippe de Fouchier were commissioned to re-develop the Grand Bazar of Lyon. HDA developed, for the team of architects, the design for a suspended, inclined façade according to their objectives of maximum transparency. The inclination of the façade diminishes reflections and optimises the transparency. The glazing is fixed to patches suspended from steel rods. The wind loadings on the façade are transferred to a wind loaded beam constructed of horizontal metal blades, which recall the blades of the curtain wall of the upper storeys.

Electric Pylons, Italy HDA: pylons designer Client: Terna Competition team: HDA, Rosenthal Contractor: Tecnopali HDA’s design for high tension electricity pylons was the winning entry in a competition held by Terna in Italy. Terna is a private national electricity provider that is undergoing a phased modernizing of their 60000km network. Their programme has a notable economical and ecological outlook and the brief invited the competitors to specifically address these issues. In the phase concerned by the competition, Terna’s objective is to reduce the length of a line supplying Rome from 1200km to 800km, by modernizing it with more efficient equipment. Terna are very conscious of the image of their lines in the public eye and in the natural landscape, and they wish to improve the environmental impact of the pylons on the landscape. Though the new pylons will cost about 3 times more than the existing ones, the reduced amount of electric lines will mean an overall cost saving. The public image is considered important enough to validate the cost of the design and that it is justifiable in considering the whole operation. HDA’s design response is based on changing the current ‘industrial soldier’ image of today’s pylons. This is done primarily by creating an elegant shape whose form is inspired by nature, instead of the more typical galvanized trellises, and secondly by what we call ‘dancing with nature’, whereby the pylons lean and swerve in response to the topography. They find a structural equilibrium by leaning into the curve of the electric cables as they follow the constraints of the landscape. In order to avoid repetitive standardization, the design uses parametric analysis and numerical tools to manageably create an individual design for each pylon, so it can respond to the specific criteria and parameters of its location.

Passerella Olimpica, Turin, Italy
HDA: footbridge designer Client: City of Turin «Every great event can be summed up by an emblem and a powerful symbol that identifies it. Performing this function for Turin and the XX Winter Olympics is the imposing, futuristic red arch of the pedestrian bridge connecting Lingotto to the former General Market. It is a symbol that along with many others, changes the city skyline, but also stands for the larger process of renewal that the city had embarked on.» Sergio Champarino Mayor of Turin The footbridge was part of the winning design of a competition for the Olympic Village for the 2006 winter games in Turin won by the Camerana team. The design is characterised by the red parabolic arch, now baptised the Arco Olympico whose inspiration is found in the concrete arches of the existing Mercati halls, thereby linking the design to it’s context. The leaning arch, the curving deck and the virtual spaces created by the cables radiating as spokes from the deck to the arch all create drama and excitement. The arch is 70m High, weighing 600T, and leans over the railway tracks that the footbridge crosses. From the arch is suspended a 150m span deck from a series of radial cables. The deck is 4m wide, and includes protective meshes and lighting. The deck incorporates dampers to mitigate vibration for pedestrian comfort. The design studies included wind tunnel analysis and full dynamic simulation studies. The bridge design is a symbiosis of engineering and architecture. The architectural composition finds it’s logic in structural expression. The forces are clearly expressed in the dynamism of the architectural composition. We understand of the passage of forces through the deck, cables and arch to the foundations. Aesthetic pleasure can be found in feeling the athletic dynamism of the structure. This is a fitting and appropriate approach for a monument to the Olympic games.

Changi International Airport, Terminal 3, Singapore HDA: facade designer Client : Civil Aviation Authority of Singapore Architect : CPG & SOM (concept) For Singapore’s Terminal 3 expansion of the Changi Airport, CAAS, the Singapore airport authority, appointed HDA to assist them in developing the facades of the airport. Local architects CPG’s initial concept for the terminal building, developed with SOM of New York, called for a cable wall for the main landside departure level entrance facade that should be as ephemeral and visually light as possible. A two dimensional net of prestressed cables spens 18m vertically from concrete floor to roof truss and 15m horizontally between the columns. Laminated tempered and heat-strengthened glass is minimally fixed to this array of cables to provide a discreet and optimally transparent glass plane. The typical facades of the building are double glazed panels supported in a uniform 2 way grid of steel framing. The mullions, varying between 6 and 18 metres high are assisted by tension rods to increase their inertia for the larger spans. The tension rod system is exploited as a support for sun shading louvers. The response to local design conditions in Singapore’s unique equatorial climactic involves critical solar protection for this entirely air-conditioned building taking into account specific sun angles using frit, high performance coatings, tints and traditional shading louvers.

Pacific Place Three office tower , Hong Kong, China HDA: entrance facades designer Client: Swire Properties Ltd. Architect: Wong & Oyuang Pacific Place Three, a 40 storey office tower, is a recent addition to Swire Properties shopping and office complex located on the frontier between the central commercial office/administration district and the more popularist Wan Chai community. The podium at the base is characterised by maximum openness and transparency such that the tower integrates itself with the surrounding small scale context. The situation inspired the design with the theme of openness, transparency and high quality innovation, to respond to the dual objective of small scale integration and a grade A office tower. The typical facades of this offices are in high performance solar protection/low-e coated glass and the entrance podium level is in a 3D cable net and point fixed glass. HDA assisted Swire Properties as consultants to consider options for the typical facades, develop the concept and geometry for the podium glazing, as well as assist the design team and contractor as a specialist consultant for the design of glazing component details and structural performance during the contractor design development phase.

Oxford House office buiding, Hong Kong, China HDA: facade and skylight designer Client: Swire Properties Ltd Architect: Wong & Ouyang Oxford House is designed with a series of elegant and transparent lightweight tension trusses that support glass walls and skylights. The tension trusses are constructed from stainless steel rods and castings. The trusses are un-braced to achieve a simple expression of structure to resist wind forces. This structural configuration is stable under uniform loading. When non-uniform wind pressures areconsidered the tension trusses take up a configuration, which is determined by using non-linear large theory deformation analysis. The glass fixings are connected to the tension trusses using carefully detailed bolted ball connectors to ensure the trusses carry wind loading without transferring local bending moments to the glass. The glass provides lateral stability to the tension trusses and at the same time it is articulated in a manner which enables the glass to float. The movement of the glass fixing is carefully arranged to prevent the system from attracting load due to movements of the super-structure. Stainless steel castings are utilized to provide freedom in the shaping of components to suit the articulation of the trusses, to provide moment free connections, and to form special details such as corner junctions and door connectors. Installation procedures incorporate adjustment devices to allow the walls to be accurately set out. Provisions are also made for long term monitoring of the pretension trusses either by manual means or by computer monitoring. These monitoring provisions are very important due to the significance that pretension plays in maintaining the stability of the trusses.

Maritime Museum, Osaka, Japan Hugh Dutton at RFR: architectural coordination and dome technical designer Client: Osaka Ports and Harbour Bureau Architect: Paul Andreu A 73m diameter glass and steel dome in Osaka bay covers a full scale replica Japanese ship. The dome is on a concrete base with deep piles founded in the sedimentary soil and includes a shore based entrance pavilion with an undersea tunnel connecting it to the dome. Hugh Dutton provided a technical design service for the steel and glass dome for the overall project in the ‘basic design’ phase and was responsible for ensuring the communication interface between the engineers Ove Arup in London and Tohata in Japan. A glass dome in Osaka’s ‘mediterranean’ climate raises the challenge of finding a solution that gives a clear view of the harbor whilst limiting the greenhouse effect and withstanding Japan’s particular structural constraints of typhoons, tsunamis and earthquakes. The dome is a gridshell structural in 216mm steel tubes with cast nodes and rod diagonal bracing. The dome crown is a cable net ‘lens’ in a circular vierendeel frame which incorporates ventilation panels. The glazing is in a specially developed laminate incorporating perforated steel sheets for shading and using the point attachment system developed at La Villette. This point fixed system has been exploited in Japan by Asahi Glass under the brand name Tempoint in collaboration with Hugh Dutton. The shading concept involved a study of the annual climate conditions in Osaka with the objective of finding optimal shading and transparency. The mean solar radiation is projected onto the hemispherical surface and represented as a series of contours of variable porosity, i.e. 90% solid at the pole, through 80%, 60% and 40% with clear glass on the equator in the north and south. The distinct pattern of the variable porosity sheeting gives the dome a didactic expression of solar energy whilst providing maximal transparency for viewers in the dome of the Osaka harbor.
