Rooftop chillers installed in Wellington

25 05 18

Work is progressing well for the Benmax team on site at the National Biocontainment Laboratory project in Wellington. With the building envelope nearing its final stages and now being close to weathertight, and construction inside continuing with the installation of wall framing and services, the focus of the team has moved from the research and development test facility to installation of the rooftop chillers.


The successful installation of three air to water heat pumps, weighing in at nearly four tonnes apiece, took place in February with the units now sitting on custom made steel plinths over the plantroom.


Given the unique challenges and complexities of the laboratory build and systems, a dedicated ‘mock up’ area was constructed on site for contractors involved in the project to trial and evaluate construction and installation methods and materials before applying them to the new building. The Benmax team was able to test ductwork systems for accuracy and alignment.

The New Zealand Ministry of Primary Industries is constructing the new National Biocontainment Laboratory at the National Centre for Biosecurity and Infectious Disease. The $87million project will replace the existing high containment laboratory that is outdated. The Benmax team are expecting to be on site until early 2019.
