What the notice says
Not fully read: this is the notice text; attached documents are not read.
TfW is seeking to establish a Framework Agreement to cover Independent Assessor services.
The proposed framework will provide specialist independent assessment and assurance services to verify compliance with railway safety, interoperability and regulatory requirements.
The framework will be divided into three lots:
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.
Further information can be found in the Tender Documents published on the Atamis procurement portal.
