## Summary

Transport for the North, a sub-central government public authority based in Manchester, is currently in the tender stage of a procurement process for the "NorTMS External Audit" project. The project involves conducting a full audit of the Northern Transport Modelling System (NorTMS), with a focus on the technical analysis or consultancy services category. The procurement is being pursued via an open competition method, with submissions required through the Delta e-sourcing portal. Interested parties must submit their documentation by 12:00 p.m. on 16 June 2025, and enquiries can be made until 6 June 2025. This opportunity falls under the service category and caters to organizations adept in CUBE model reviewing, with proficiency in Python, to ensure efficient audit execution.

This tender represents a significant opportunity for businesses specialising in technical auditing and consultancy services, particularly those with expertise in transport systems and modelling. Companies with a strong track record in CUBE model reviewing and Python programming will find this contract fitting, given the specific requirements highlighted in the tender. It encourages competition from SMEs, providing a projected contract value of £50,000 gross, with a potential contract extension of up to three months. This could be an ideal growth opportunity for firms looking to expand their footprint within the transport sector auditing domain, offering both a strategic partnership with a prominent public authority and the potential for future collaborations.
