Lot 1 – Assessment Body (AsBo): Independent assessment against Common Safety Method (CSM-REA) requirements.

Lot 2 – AsBo / Approval Body (ApBo) / Designated Body (DeBo): Safety and interoperability assessment services against National Technical Specification Notices (NTSNs) and National Technical Rules (NTRs).

Lot 3 – Independent Competent Person (ICP): Independent verification of compliance with ROGS requirements.

The framework will support assurance activities across TfW rail infrastructure projects throughout the project lifecycle.
