Crossrail Plumstead Maintenance Facility Carbon Management in Infrastructure
A new maintenance facility was required to be constructed east of Plumstead Railway Station, London, as part of the Crossrail project, including a maintenance building, accommodation building, undercover stores and associated external works such as car parking and lay down and loading bays.
This pioneering study within the rail industry carried out a carbon assessment in line with the principles of the BSI Standard for Carbon Management in Infrastructure to identify the baseline embodied capital carbon of the designs and to provide a framework to identify potential opportunities for reduction during construction and operation.
This data was then inputted in to the RSSB Rail Carbon Tool. Each material was identified in the tools material library and the tool then applied a carbon factor to calculate a figure in kilograms of Carbon Dioxide Equivalent (CO2e).
High impact carbon materials were identified, and it was calculated that substituting general concrete and steel with ground granulated blast furnace slag or pulverised fuel ash concrete and recycled steel respectively, could reduce the total embodied carbon of the Plumstead Maintenance Facility by 30%. Liaison with the principal contractor was undertaken to recommend the use of these alternative materials in construction.
