Our services include Structural Engineering. Key to this effort is the research and development we maintain to ensure we are abreast of the latest technology. as building envelope design becomes ever more complex due to increasingly stringent energy requirements and material and technological advances. Eckersley O’ Callaghan is a member of the Centre for Window and Cladding Technology eckersley o’callaghan . Architectural trends towards more geometrically complex forms and tactile cladding materials require a greater understanding of materials – of their structural characteristics. We have adopted the latest analysis software to enable us to design systems that achieve and exceed these goals. who also has a deserved reputation for his facade solutions on complex projects. led by Phil Khalil.Facade Engineering Our experience with structural glass led us to develop a group that can extend this area of expertise into more holistic facade design and engineering. Facade engineers have assumed a central role in architectural and engineering design teams in recent years. giving the building a new sustainable lease of life. As a practice we take a very sustainable view on design and at the core of this is the reuse of existing buildings. This is strengthened by an alliance with our sister company in New York. These challenges require specialist engineers as part of the design team from the early stages of design. Our specific experience in closely working with industry partners to extend the possibilities of fabrication places us in a unique position to ensure that every facade is conceived with fabrication technology and budget to the fore. in which condition and remedial works required can be identified and specified. Our service includes full design. and current thinking in energy efficient building skins.

The stiffness of the glass wedge portion is far greater than that of the cantilevering steel walls enclosing the main retail zone and hence there is a complexity in resolving the junction between the two which has been subtlety addressed as a concealed movement joint at the first truss. Structurally the building is effectively two sections.

The panels required the design and procurement of a specially designed autoclave in order to carry out the laminating process at this scale. located in George Street Sydney. the vertical glass columns support the steel roof purlins and provide lateral restraint for the main facade glass. uniquely characterised by its arts educational history and burgeoning young family population. the project is considered a refurbishment because some structural elements of a previous building were protected and utilised in the structure of the new building. eckersley o’callaghan . A dramatic three storey linear void. We were responsible for the structural design of the whole building. Each monolithic sheet is 14m tall and 3m wide held off the building on a glass supporting frame. The glass panels which form the storefront facade are the world’s largest laminated glass sheets.

Pennsylvania Architect: Pfaffmann + Associates Client: Port Authority of Allegheny County Completed: July 2012 The Gateway Station is the centrepiece of Pittsburgh’s 1. Working with Carpenter / Lowings Architecture and Design. Collaboration with the architect and installers allowed for a design which minimised glass thickness by removing the need for bolted connection creating a delicate glass surface uninterrupted by exterior surface connections. London W1 Gateway Station Pittsburgh. The sculpture is lens shape in plan and 8m x 8m in elevation. The principle challenges lay in the glass facade. This enabled us to propose annealed glass fins which in turn had the significant processing benefit of being polished after lamination yielding a perfectly crisp and polished edge. Hong Kong Architect: Bohlin Cywinski Jackson Client: Apple Inc Completed: 2011 The IFC HK store is located in the Central area of Hong Kong and is Apple’s first entry into this market. Both the facade and the other glass elements also had to be capable of accommodating the significant deflections of the bridge structure.000 sqm of structural glass in this scheme the ability to simplify the connecting parts enhancing the aesthetic led to a very successful outcome. It represented a departure from a bolted glass connection to a new type of encapsulated fitting where the metalwork is bonded into the body of the glass. glass spiral stair. This led to no visible bolted connections between glass elements and enhanced the minimal appearance of the facade. EOC provided extensive justification of the design. the building bridging the street with a 40m span. through analysis and through both large and small scale performance tests.

The simplicity of the connection allows each fin to be angled differently relative to the face glass panels without the need for custom machined parts. London The Village Architect: Gabellini Sheppard Client: Westfield Completed: 2008 EOC were approached by Gabellini Sheppard of New York to assist them with a new concept storefront design for this landmark retail development in West London. The proposals lay well outside the conventions of facade and glass engineering in Hong Kong and the strict local construction guidelines led to long negotiations with the building authorities during the permitting process. The architect was very keen on creating a crystal jewel like effect with the storefronts in the Village to evoke the exclusivity of the merchandise being displayed. The facade had to be engineered to resist the extremely high wind loads that Hong Kong sees during Typhoon season. glass balustrades and internal mall storefront. Drawing on the laminating technology we previously developed we conceived a simple connection detail that eliminated the need to drill holes in the glass fins. thus enhancing the jewel like effect desired.
