Ricardo's accredited Certification business has been performing key assurance roles during the construction of London's Elizabeth Line (also known as Crossrail during its build stages).
One of Europe's largest infrastructure projects of recent times, it consists of 42km of new tunnels fitted with track, overhead electrification and related cabling, as well as ten new or remodelled stations that have been dug to a depth of up to nine storeys below ground level.
Once fully operational, the Elizabeth Line will add 10% capacity to the capital's rail network, bringing 1.5m more people within 45 minutes of London's main business districts.
Key assessment roles awarded to Ricardo
Ricardo Certification* was appointed as the Notified Body for the central tunnelled section in July 2012, with a remit that covered the design, construction, testing and commissioning of the various structural sub-systems, including the 21kms of twin-bore tunnels. Following the UK's departure from the EU, the role was referred to as Approved Body (ApBo) (see below).
As the appointed ApBo for the Elizabeth Line, Ricardo Certification has closely tracked every step of the build to provide conformity assessments against the relevant requirements of the Interoperability Directives. These assessments give project managers assurance that legal requirements are being met at every key stage of the programme.
As one of the first large-scale railway projects in the UK to be built in line with the Interoperability specifications, Ricardo's expert teams have taken on pathfinder roles throughout the build programme, advising on the extent to which regulations - both existing and emerging - apply and on the development of any specific Technical Rules when necessary.
In 2013 our involvement was extended to include Assessment Body work before the infrastructure was transferred from the build contractors to the eventual operator.
