PROJECT VALUE

$1.5 Million

STATUS

Completed - January, 2019

NRG Services were engaged by McNab to carry out the electrical and mechanical components of the historic multi-level Toowoomba South State School.

Originally opened in 1865, major renovations were carried out on the building including a refurbishment to the existing building and the construction of a modern three level extension containing a secure basement carpark and two levels of office space for the Catholic Education Offices in Toowoomba. The former indoor sport centre was also converted into a conference hall with the ability to accommodate the Catholic Diocese’ large staff numbers.

Electrical works comprised of the supply and installation of a 1000kva pad mount transformer to Ergon requirements, new main switchboard, distribution board and generator connection point for future provisions.

Electrical works also included site wide electrical and communications underground reticulation; complete data and communication installation; security intruder detection and alarm system, access control system and CCTV system; and external carpark, pathway and landscaping lighting.

The installations of a new main, submain and sub circuit cabling for general light and power requirements; and dry fire and BOWS System to AS1670 standards were also completed.

To allow electrical works to be completed, an under-bore of the adjacent Warrego Highway was required. Due to the complexity of the task and necessary coordination with utilities, asset owners, local council and the Department of Transport and Main Roads a significant amount of pre-planning was necessary to complete this component.

The mechanical components of the project comprised the supply and installation of VRV Air-Conditioning, fresh air systems, extraction systems and integrated controls to three of the facilities blocks.

The air-conditioning design included a combination of commercial office ducted air-conditioning systems, most of which were concealed in bulkheads and concealed ceilings, and single split systems in communication areas.

The installed commercial office systems are monitored by a Daikin Intelligent Touch Manager, servicing over 25 separate areas within the facility. The system is designed to monitor and control the air-conditioning system as well as offer proportional power distribution technology – allowing the client to monitor the energy consumption of each system throughout the building.

Additionally, a 70kw package air-conditioning unit was installed to service the multi-purpose hall. The system is designed to support economy mode and in the right conditions prefiltered outside air can be used to cool or heat the space – in turn, saving on energy costs.

Mechanical works also included the installation of a cold room in the multi-purpose hall’s kitchen along with extraction to the kitchen and amenities areas.
