    Brief

    The Department for Transport (DfT) seeks a qualified supplier to provide professional support and maintenance services for its Transport Analysis Guidance (TAG) software and related modelling tools. The Transport Appraisal and Strategic Modelling (TASM) division uses these tools to support evidence-based decision-making in transport policy. The successful supplier will be responsible for: maintaining and updating TAG software to reflect current research and best practices; providing technical support to licensed users; assisting with related transport modelling sub-tools as needed; and potentially developing enhancements to existing tools. The contract runs for 38 months from 1 May 2026, with an optional extension of up to 12 months. A handover from the current supplier is planned for April 2026. Suppliers should be prepared to discuss the scope of any additional tool support activities beyond core TAG maintenance. This is an opportunity to support critical government transport appraisal infrastructure used across multiple stakeholders.
