If you live in Brisbane and travel through Fortitude Valley you may have noticed the ongoing development on the Corner of Ann St & James St. Formerly home to a car dealership, Laing O’Rourke are developing three buildings on the site. The 13 storey commercial building featured in this article – designed by Rice Daubney Architects, as well as a mixed-use building and a residential tower. The commercial building fronts on to Ann st, and G.James are currently working to install the building’s façade.
About the Façade
The coloured & grey panels on the lower levels of the building are glazed with ceramic painted glass. Above this the curtain wall features large IGU panels, and a unique “ribbon” sunshade solution designed by Rice Daubney & fabricated by G.James. G.James is also glazing the shopfronts for the ground floor retail space.
The sunshading is fabricated from perforated aluminium sheet, and supported on extruded aluminium framing which includes true curved extrusions. The horizontal to verical twists ribbon are curved in two axis. The custom designed framing system incorporates G.James bespoke sunshade fixing detail which allows for support of the sunshades directly off the curtain wall panels. All attachments of the sunshades to the facade occur outside the external rain-screen line, without any penetrations through the curtain wall panels – mitigating any potential water leaks to the façade. G.James’ sunshade fixing detail enables easy removal & re-installation of the sunshading devices in the event of glass replacement. The sunshade fixing detail’s rigid connection to the facade resists the imparted wind loads, and minimal diagonal bracing provides redundant support in the event of a maintenance abseiler standing on the sunshade.
The design of the building features a blade-wall on the tower – originally to be constructed from pre-cast concrete. Design and construction issues however meant that a non-traditional approach was more optimal – G.James developed an engineered solution for the feature blade wall in lightweight composite-aluminium clad panels that cantilever outside the facade by a projection of approximately two and a half metres, and continues up the full height of the tower.
Behind the Scenes
G.James have been working intensively with the Architect, Rice Daubney, to try to turn their vision into reality well before we began work on site. Since September 2011 there have been multiple, full-scale, visual mock-ups prepared by G.James on this project, working closely with the Architects to ensure the fine detailing is achieved.
Check Back for Updates
G.James is continuing to work on the façade, completion of the project is expected to be in early 2013. G.James is also working on the two other buildings in the development – the mixed use building & residential tower, so check back for more updates as the development progresses.
