TfL is looking to appoint between 18 and 34 consultancies to the four-year framework, which is valued at £1.5 million-£2 million.
The framework is split into six different lots: corporate identity and graphic information creation; corporate design implementation; digital services; cartography; typesetting and artworking and above-the-line and campaign-based marketing.
Of these lots, the above-the-line work alone will be worth an estimated £1 million-£1.4 million.
Work in the corporate identity lot will include logo and pictogram design and signage design, while the corporate design implementation lot will feature projects such as publications and reports and vehicle livery design.
The digital services lot, meanwhile, will include work such as apps and E-book design.
The cartography lot covers map design and development, the artworking lot covers posters, publications and leaflets and the above-the-line lot will include customer-facing campaigns.
