Civils Assessment Framework Agreement (CAFA)

Pell Frischmann was a supplier for the 5-year Civils Assessment Framework Agreement (CAFA) in alignment with OPR Control Period 5, and also acted as a supplier on the preceding Civils Examinations Framework Agreement (CEFA) during OPR Control Period 4. The goal of these frameworks was to establish the condition and confirm the capacity of Network Rail’s structures portfolio which forms an integral part of their asset management process. The initial 5-year CAFA programme was subsequently extended through to 2020.

What we did

As part of the 5-year framework, Pell Frischmann supplied numerous Level 0, Level 1 and Level 2 assessments of a wide range of structures. These included metallic, concrete and masonry rail underbridges, overbridges, footbridges, train shed roofs and station canopies.

A key part of the delivery involved undertaking inspection for assessments to determine the condition and structural arrangement of the structures. As part of our approach for continuous improvement, we work closely with our inhouse Surveying Team to look for opportunities to add value by implementing innovative and non-traditional methods of inspection. Working within a rail environment requires a high standard of safety, which we ensured with careful planning and pre-inspection reviews and production of Work Package Plans and Task Briefing Sheets.

Our engineers have significant expertise in undertaking advanced methods of analysis providing strong capability in delivering Level 2 assessments involving finite element modelling and non-linear analyses.

Pell Frischmann also provided additional services during the frameworks including data collection for national bridge strike risk register and backlog reviewing of previous Level 1 assessment reports.


Pell Frischmann’s role on the framework contributed to the continued safe use of Network Rail assets across the rail network. In addition to current load ratings, Pell Frischmann provided considered recommendations for maintenance and repair works to allow the client to return structures to their desired capacity and maximise the serviceable lives of their assets. Pell Frischmann also assisted Network Rail in preparation of Business Plans for Control Periods 5 & 6.

Stuart Cox, Pell Frischmann’s Transport & Land Development Business Unit Director, said:

The Pell Frischmann Team is proud of their long service to Network Rail and delighted in playing a major role in maintaining the critical rail infrastructure on which the travelling public depend.
