VAE Group were engaged by Mirvac to undertake Replacement of the Chilled Water Plant at the 35-storey 101 Miller Street, North Sydney.

We removed two redundant Trane chillers, and associated pipework, pumps, and electrical switchboards and replaced them with new equipment.

Two new 1250kW SMARDT water cooler chillers were installed. New pipework was constructed to suit the new layout of the chillers, reducing the footprint, and allowing more space for an additional chiller to be installed in the future.

Our internal electrical, mechanical and automation engineers, and drafting team designed and engineered upgrades for seamless changeover and operation of the plant.

VAE also supplied and installed a Tridium (Distech) based plant management system to control the central chilled water plant. This system was designed, engineered, and is now maintained by our in-house automation team.

Low Load Cooling Tower noise was a big concern for the building. VAE designed and installed a Cooling Tower staging system to allow for reduced operational usage of the cooling towers. This solution added great value to the site and reduced the need for expensive noise attenuation. VAE offered a distinctive point of difference providing experienced key technical staff, methodology, and engineering expertise. Presenting our client with one point of contact for the engineering, construction, warranty, and long-term maintenance of their critical infrastructure.
