## Summary

The Rail Safety and Standards Board (RSSB), located in London, has successfully completed the procurement stage for the Safety Risk Model (SRM) version 10 upgrade project.

The contract period commences on 5th May 2026 and runs until 30th December 2026, with a potential extension up to 30th December 2027 subject to performance and need.
