HSBC Centre (Projects)

The upgrade of GPT’s 580 George Street location aimed to deliver substantial carbon reduction initiatives and bring the building to a better than NABERS 4 Star Energy rating.

A.G. Coombs was appointed to the role of Energy Services Contractor by the GPT Group following a competitive tender process.

This role has seen A.G. Coombs deliver a broad scope of upgrade works to result in guaranteed energy cost reductions and a 4+ Star NABERS Energy rating.

Changes to the building included substantial mechanical plant and air conditioning system upgrades, lighting system enhancements and a new state-of-the-art Building Management and Control System (BMCS). The BMCS incorporates comprehensive energy metering and reporting capabilities, including a real time energy performance dashboard.

As part of project delivery, A.G. Coombs implemented a best practice construction Environmental Management Plan (EMP) to minimise the environmental impact of the upgrade.

“Whilst such a project is challenging, especially in an EPC, undertaking complex multi system works in occupied buildings without disrupting the tenants is one of A.G. Coombs’ specialties. The implementation phase was set for completion ahead of schedule and met client requirements”. Craig Walter, Project Manager, A.G. Coombs

A.G. Coombs has provided technical capability for this project entirely in-house through the close integration of its Advisory and Projects business units. This well-managed expertise aids with mitigating risk for GPT, as well as for JLL and the tenants.
