Transport for London is looking to sign a series of framework contracts worth between £40m and £70m over the next four years.
The organisation, a heavy user of SAP software, is looking to recruit up to 100 suppliers with experience in areas such as project management, business analysis, and software development in both SAP and other IT projects.
TfL plans to make services available to other bodies, including the Greater London Authority, British Transport Police, the Olympic Delivery Authority, London TravelWatch, and London borough councils to implement, consult and support IT work.
Suppliers will work in system implementation, IT consultancy and guidance, datacentre hosting services, and managed support.
Suppliers interested in participating in the framework agreements should contact Transport for London and register on TfL's eSourcing portal by 12 February 2010. PQQ documentation will be published on 18 January 2010.
