The team have produced “Environmental Scorecards” during the Guide to Rail Investment Process (GRIP) 3 option selection stage of the design process to increase awareness of the environmental impact.
The early design stage is where we can make most impact on the sustainability of a construction project. However, when faced with several design options, cost, time and a workable solution are prioritised and sustainability is often overlooked.
What we did
At Skanska we recognise that the most sustainable option is often also the most efficient. We wanted to develop a simple tool that would give a quick comparison of the sustainability of each design option. The hope was that this would raise environmental awareness and positively influence the decision of which option is carried forward and developed into the final design.
We therefore developed the “environmental scorecard.” This is a simple comparison table that gives the approximate energy, carbon and water consumptions for each option based on material quantity. We also included the same values for a recommended more sustainable material, e.g. recycled steel. It is colour coded red, orange and green to allow a quick comparison of the options.
To date, the scorecard has been included in 25 High Level Options Reports and presented to the Network Rail team as part of the option selection process.
The scorecard increases awareness of the environmental impact of each option, influencing their decision. This will help to:
• Reduce energy use
• Reduce our carbon footprint
• Reduce water consumption
