A MESSAGE FROM GANDEN’s MANAGING Director

GANDEN Engineers and Project Managers is delighted to team with UGL Limited and Alliance Automation on the QUU Southern Treatment Plants Program.

GANDEN has invested heavily in its people, its relationships and its infrastructure to be Queensland’s Leading Water Industry Designer. I am extremely proud of the GANDEN team that has successfully delivered designs of upgrades to many water and sewage treatment plants across Australia. Please view some of our recent wastewater treatment plant projects below. There is no other design team in Queensland that has the recent treatment plant design track record and proven capability of the GANDEN team.

GANDEN has an exclusive arrangement with UGL Limited to provide the following for the Program:

• Process Design
• Civil Design
• Mechanical Design
• Hydraulic Design
• 3D / 4D Modelling
• BIM
• Commissioning Assistance

GANDEN received offers from four major contractors to provide exclusive design services. After careful consideration, I decided that a UGL | GANDEN | Alliance Automation team was the best team to deliver the required outcomes for QUU.

My team is keen to continue building on its good relationship with QUU, forged with the successful completion of the Luggage Point and Oxley Creek designs.

We have recenly acquired significant office space close to Green Square Close. GANDEN is happy to offer this space as a shared resource for the Program.

I provide my personal guarantee that GANDEN will provide the resources, personnel, commitment and behaviours expected by QUU, UGL and Alliance Automation to successfully deliver the ECI (including RAMP) and Works Delivery Phases for the entire Program.

With regards,

Darron Nutt
