What is being bought

The NorTMS Audit is to undertake audits as required of the Northern Transport Modelling System (NorTMS), a Cube-based VDM with a focus on intercity rail in the North of England. These will be required on a call-off basis when a stable model release is available. After each audit the supplier will be expected to provide an audit report with recommendations for areas requiring improvement. This will be subject to a one+one+one year call-off basis. TfN requires a supplier who is 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, unless the work that was delivered relates to the audit of NorTMS. The scope of work required for each NorTMS audit underpins the following objectives: •Provision of a full audit of all NorTMS inputs and outputs with the aim of instilling confidence in NorTMS for its use in modelling works and supporting business cases. •A review of each version of NorTMS following model updates and improvements prior to implementation on programme. •To understand the fitness for purpose of NorTMS in its use for assessing schemes for Northern Powerhouse Rail (NPR). •Production of a comprehensive audit report giving a RAG rating of all the model elements reviewed. •A final report comprising of a plain English summary of issues identified (for a general audience) and a detailed technical report (for a modelling audience) with potential recommendations for areas requiring improvement, an outline of best practices in CUBE and the application of CUBE as a modelling tool.

Comparable-procurement analytics

Benchmarked against retained Find a Tender procedures with CPV division 71. The category anchor is Technical analysis or consultancy services (71621000); this is a deliberately broad market comparator. The comparison is shown at several levels rather than pretending one company or region is always the best benchmark.

Comparison setProceduresReported bids per procedureNamed award suppliersPrice evidence
Market: CPV division 715,4134 median · 32.3 average (1,825 of 5,413 with a bid count)4.1 average (2,025 of 5,413 with named award suppliers)Not published

“Reported bids” is an official aggregate, sometimes reported per lot; it is the closest available competition measure. “Named award suppliers” are winners, not all applicants.

Price-outcome signal

Not enough comparable procedures currently publish both a GBP tender value and a usable lowest-valid-bid value to calculate a responsible price-reduction benchmark. Tenderline deliberately does not infer a saving from named award suppliers or from missing award values.
