The refurbishment of interiors in the ClockTower Building at the University of Auckland included practical acoustic solutions by Earcon Acoustics designed for minimal impact on heritage features.

With its distinctive clock tower and ornate windows, the ClockTower Building at the University of Auckland is one of the city's most significant and beautiful heritage buildings. So it was no surprise that heritage considerations were to the fore when acoustic specialist Earcon Acoustics worked with University of Auckland Property Services on a recent upgrade.

Director Fadia Sami says the building is now home to the Vice Chancellor and a hospitality suite, with several new offices and meeting rooms.

"The existing floor system needed to be upgraded to reduce airborne and impact noise issues. But because this is a heritage building there were features that could not be changed or concealed, including decorative ceilings and timber beams. The upgrade needed to protect these."

Acoustic solutions for the renovated ClockTower Building at the University of Auckland, by Earcon Acoustics, included injected insulation in heritage beams, direct fixed Asona panels and a Tascor raised floor.

Earcon Acoustic's solution was to specify a direct fixed acoustic ceiling from Asona, which absorbs noise to control the liveliness of the space, and to provide a comfortable acoustic ambience.

The existing timber floor system with its squeaky floorboards was repaired, and a new Tascor raised floor added. This was then carpeted.

New acoustic walls were also built," says Sami. "Wavebar heavy vinyl insulation was then placed within the ceiling cavities, and the hollow timber beams were injected with insulation that has minimal effect on the wood.

"The close collaboration between University of Auckland Property Services, Salmond Reed Architects and contractor Hawkins Interiors helped to deliver a successful project, within a reasonable budget. The building retains all its beautiful heritage features and is suited to the needs of a new-age world-class university."

Other projects by Earcon Acoustics include the University of Auckland Newmarket Campus, Fonterra New Viaduct Building and the Hobsonville Point residential development.
