HS2 – UK High Speed Railway

Project Details

  • Client: HS2
  • Type: Infrastructure
  • Location: United Kingdom
  • Date: 2018

Cerclos have been engaged by HS2 to provide life cycle design software eTool.

HS2 is Europe’s largest infrastructure project, designed to increase capacity on the UK’s railways and improve connectivity between eight out of 10 of Britain’s biggest cities, creating thousands of jobs and rebalancing our economy. It will run between London and Birmingham from 2026, extend to Crewe by 2027 and then link to Manchester and Leeds from 2033 with HS2 trains continuing to cities including Newcastle, Edinburgh and Glasgow.

The tool will initially be used to develop baseline, against which design options can be assessed.  As the design progresses, HS2 subcontractors will take on LCA modelling tasks to further develop the models and identify further opportunities for improving the life cycle performance.  Through using eTool’s unique enterprise functionality, multiple users can review and collaborate effectively on large complex LCA models, a feature that will enable this sequential and collaborative assessment.

Results Summary

Results are used for internal concept design at this stage. In order to measure, reduce and report on carbon emissions, materials efficiency and wider embedded environmental impacts, HS2 have adopted a life cycle assessment (LCA) approach. This modelling will include impact analysis across all life cycle stages from the extraction of raw materials through to processing, transport, use and disposal. Using eTool, the modelling will be conducted in accordance with applicable standards including BS EN ISO 14040, BS EN ISO 14044, BS EN 159783 and PAS 2080. The LCA modelling results will also be used to demonstrate achievement of credits within BREEAM Infrastructure.

This assessment will be conducted internally at HS2 and certified by Cerclos.
