Using eTool made what would have been a very complex process manageable and added valuable information to the project.

I highly recommend integrating eTool at earliest project stages to support systems thinking and inform decisions.

eTool increasingly has more data in it that we can use as baselines… eTool gives us that capability for the designers to optimise their designs linking into Autodesk and other CAD based models… We [also] have some big plans to do that in HS2 in terms of turning the outputs from eTool into our digital twin so that everybody has access to that data and that it’s meaningful to them. [This way it] can spark the right types of conversations about reducing carbon and net zero and make it more inclusive.

eTool’s Life Cycle Assessment helped us understand how future impacts from energy, water, materials, recycling and waste will influence Greenhouse Gas emissions and the whole-of-life costs of our project. It enabled us to identify and compare different options to support informed decision-making with our Alliance partners and our target of a sustainable, Green Star certified railway station.
