Walking on air

An aerial pedestrian walkway linking two parts of a development across a public street would be most economically achieved by a straight, point A to B bridge. However, when this economic, expedient concept is replaced by a snaking aerial sculpture, it speaks volumes about the intentions of the client and architect, and also of the skill of the construction company that achieved it.

Project and construction management company Arrow International has worked on the Vision Waitakere Gardens retirement development since 1997. From the outset, demand for units was strong, so in 2006 construction began on a further 84 apartments, separated from the main site. Recently, a futuristic bridge was added to provide a safe, scenic stroll for residents between the two areas of the development, says Arrow's project director Neil Winstanley.

"First conceived by Pacific Environments Architects and the client, Vision Senior Living, it was then our job to turn their idea into a viable working structure," says Winstanley. "The skybridge had to be installed over a road, and at height requiring careful consideration of how best to approach the construction."

Arrow's solution was to build the bridge in three sections off site, and then crane the prefabricated structure into place between the existing buildings. This had the dual advantages of minimising interruption to traffic and to the residents of Waitakere Gardens.

Every consideration was given to safety as well as efficiency. For example, all the fittings for the skybridge's glazing and roofing were installed in the factory to enable faster installation on site and reduce the amount of work to be carried out at height.

"Ultimately, the bridge adds greatly to the functionality of the development and provides a striking aesthetic for passers-by as well as users," he says. "It was testament to Arrow's versatility that the development remained operational throughout its construction."
