SWRL-xtension-825x402 south west rail linkEdge Environment recently delivered a whole of life study for TfNSW’s South West Rail link. The triple-bottom line analysis incorporated financial, environmental and social analysis into one view and toolset.

Three design scenarios were compared and modelled with their respective Net Present Values calculated over the life of the asset. The study enabled the TfNSW Sustainability Design Guidelines to be tested, while also assessing the bottom-line value of particular sustainability initiatives against a suite of asset types – stations, car parks, depot/stabling and civil infrastructure.

The study applied international best practice standards and was reviewed by peers on an international level.
