Stacey Agnew Pty Ltd formed in late 2009 as an independent consultancy offering clear thinking, analysis and design in a range of engineering and operational fields. Our core business is tunnel ventilation, underground fire safety and associated electrical and mechanical disciplines in civil infrastructure (mainly road and bus tunnels, railways and metros). Current core skills are in applied fluid mechanics, network analysis, system controls and mechanical design. Our approach to consulting business is to seek work where we can add value, and we see a prime responsibility to advise when better outcomes could be achieved by a different approach. We are constantly thinking about the wider picture to give context and direction to the task at hand. A focus of flexibility of approach and open-mindedness combine nicely with our technical background in fluid dynamics in the tagline “Fluid Thinking”. Major project involvement includes Clem7 Tunnel (Brisbane), World Trade Centre (NY), Delhi Metro, and the Inner Northern Busway (Brisbane).
