CROSSRAIL LIBRARY | INSIGHT
As the Crossrail programme is now complete, the
organisation set up to deliver it has been demobilised but it’s not just the railway that remains as a result – Crossrail’s Learning Legacy is still available at:
https://ll.crossrail.co.uk/ The Crossrail Learning Legacy Programme was
established in 2015 with the objective to collate and share lessons learned, best practice and innovation from the Crossrail project for the benefit of future projects and programmes. The Legacy Programme ran from mid-2015 to May
2023, with a hiatus between July 2018 and January 2020 while the project was reorganised to address delays. Up to 2018, 651 items were published in six 6-monthly tranches. This was over 25% more than the target the team set for itself. From 2020 the items were published as soon as available and the target of 25 new items was surpassed massively, with 159 added including those from a final technical papers competition and a third journal. The establishment of a Learning Legacy was
prompted by a recommendation to the Department for Transport (DfT) by the Public Accounts Committee (PAC) that the experience of delivering the Crossrail programme be shared for the benefit of other taxpayer funded projects. It followed in the footsteps of the London 2012 Olympic Delivery Authority’s Learning Legacy and involved sharing a combination of new and existing documentation through a dedicated website. The types of content include micro-reports, case studies and technical papers, all of which are items written for the Learning Legacy by those involved in delivery, and good practice documents and datasets, which are items produced during the work, such as processes and procedures and suites of data, which are shared for others to use, adapt or study.
