BREEAM
Summary
The use of BREEAM for underground stations was pioneered on Crossrail. This required the adaptation of the BREEAM Bespoke 2008 methodology to enable BREEAM assessments to be carried out on the Crossrail project works relating to underground train stations (new works and major refurbishments). Crossrail worked together with the BRE to develop a tailored set of BREEAM criteria to facilitate the environmental assessment, measurement and benchmarking of Crossrail’s underground stations at the design and post construction stages of assessment.
The resultant tailored criteria set followed the principles of existing BREEAM schemes in terms of structure, content and application (in particular BREEAM Bespoke) yet defined appropriate and consistent assessment requirements criteria for Crossrail’s underground stations. As the methodology was applied various issues came to light resulting in the further modification and deletion of credits as appropriate such that the criteria evolved over a number of years.
Any future projects are likely to use later revisions of BREEAM Bespoke, however, the experience of delivering BREEAM on Crossrail does highlight some of the issues that would be pertinent to other underground stations and this is captured in this paper.
