## Summary

The procurement process for the "NorTMS External Audit" was conducted by Transport for the North (TfN), a sub-central government public authority based in Manchester, United Kingdom. The procurement related to technical analysis or consultancy services within the transport sector, focusing on auditing the Northern Transport Modelling System (NorTMS). The tender was executed through an open competition method and was below the threshold value. The contract has been awarded to HASKONING UK LIMITED, a large supplier, with key dates including the contract period from August 9, 2025, to January 21, 2026, and the potential for an optional two-month extension. The process has moved through the planning and tender stages to the award stage as of August 29, 2025.

This opportunity presents clear possibilities for growth for companies specialising in technical audits and consultancy services, particularly those with expertise in transport modelling and Python coding. It encourages large firms or SMEs with experience in technical analysis and consultancy to engage in future opportunities with TfN, fostering a robust partnership in public transport projects. The focus on CUBE model reviewing skills suggests that IT and software companies with a niche in transport systems could find a lucrative market, demonstrating the potential to expand service offerings within the public sector. The stipulation for non-involvement with NorTMS-specific prior work ensures fair competition and the inclusion of new entrants in the bidding process.

## Notice

Transport for the North (TfN) wishes to appoint a supplier to undertake a full audit of all the model inputs and outputs in the Northern Transport Modelling System (NorTMS) and to provide an audit report with recommendations for areas requiring improvement. The supplier must be an expert CUBE model reviewer with competent Python skills as some elements of NorTMS are coded in Python, and who has not worked with NorTMS or related to any TfN framework directly involved in NorTMS.
