  • Abstract

    This is the fourth in a series of Crossrail Learning Legacy webinars focused on the Environment Theme, in conjunction with our partners CIRIA and IEMA.
    The construction of Crossrail resulted in the generation of over 7 million tonnes of excavated material, of which over 98% was beneficially reused. Crossrail adopted a client-led approach to the reuse of the material (whereby the destination sites and means of transportation were specified to contractors by Crossrail) together with flexibility to allow some of the individual contracts to make their own arrangements for beneficial reuse as appropriate.
    This webinar describes the approach followed by Crossrail to reuse the excavated material from the project, identifying the main stages of the process, the key activities undertaken by both the client and contractor and the lessons learned from implementation. Benefits of this approach will be demonstrated and include:

    • Creation of a landmark conservation project
    • Reduction of programme risk
    • Development of infrastructure to allow transportation by water and rail

    It will be of use to clients of major infrastructure projects who are looking to adopt a similar approach to the reuse of excavated material. It will also be of use to any project or contractor who is disposing of excavated material.
