Optus Telephone Exchanges

Published 31st August 2022

Waterman was appointed to provide the building services design for a high-density cooling project initiative. The purpose of this project was to provide a building services infrastructure upgrade to meet the exchange growth and operational requirements.

There was a need for the provision of precision cooling within the telephone exchanges to cater for equipment generating heat which has the potential to exceed, or is already exceeding, the capacity of the existing mechanical cooling system. Optus have deployed a high-density water-cooled system that provides precision cooling and treatment of air within local areas and racks.

A high-density cooling system is already installed and operational at the Moorooka site with current projects at Regency Park and Lockridge.

In general, the design took into account that facilities are operational 24 hours, seven days a week and any works that impact on the normal operations of the facility must be incorporated accordingly. Typically, this would include, but not be limited to temporary cooling, alternate power supplies and protective screening.
