Judith Griffiths was the Delivery Certification Manager on Crossrail and was responsible for managing the requirements for contractor self-certification across the central section.

Joining the project in 2010, Judith and the Certification Team monitored compliance and performance of each contract, from demolition and enabling works to commissioning of rail and station systems. Having overseen the production and acceptance of almost 17,000 certificates during her 12 years, and the completion and handover of all but one station, Judith left Crossrail following the opening of the Elizabeth line in 2022

Judith is a member of the Chartered Quality Institute and achieved Chartered Quality Professional status through completing the Crossrail CQI Quality Training course in 2013.

20 years of Judith’s 23-year career have involved self-certification and assurance records, for both contractor and client on major infrastructure projects in the UK.
