UK7 - Contract Details Notice
Summary of the contracting process

The Met Office, located in Exeter, has recently concluded the award stage of a procurement process concerning the "Implementation of FAB in Momentum Simulation Systems," focusing on a software migration and development initiative. This tender, categorised under services related to the design and execution of research and development, involves collaboration with the Bureau of Meteorology from Melbourne, Australia. This project aims to transition from an outdated build tool to a modern one called Fab, aligning with the migration from Subversion to Git. The procurement was performed using a direct method below threshold and without competition, indicating a strategic allocation. The contract period spans from 6th January 2026 to 30th September 2026, with the contract having been signed on 24th December 2025. The total contract value is £90,000.

This procurement opportunity provides significant growth prospects for businesses specialising in software development and version control systems. The tender primarily targets entities proficient in transitioning complex software stacks and creating reusable tools for simulation systems. Given the collaboration with a large organisation such as the Bureau of Meteorology, companies with international experience and expertise in research and development of simulation systems are particularly suited to such engagements. Small to medium enterprises skilled in Git environment setups could find strategic opportunities due to the ongoing transition to Git and the development of Fab scripts, potentially opening doors for further collaborations with partners in the Momentum Partnership.

Notice Information

Notice Title

Implementation of FAB in Momentum Simulation Systems

Notice Description

The Met Office is preparing an important change in managing their software stack, migrating from the old Subversion-based versioning system to the modern Git. Besides required changed to all existing suites, there is also a need to replace the outdated build tool called FCM: FCM does not support git, has shortcoming in supporting LFRic, and is written in a language that is not well-supported by Met Office developers anymore. 6 years ago, the Met Office decided to implement a new, modern build system called Fab that addresses the shortcoming of FCM. While there was an initial, proof-of-concept release, with the help of the Bureau of Meteorology (BoM) Fab was extended to support missing features, and it was shown to be well-suited to build LFRic-based applications. This work will involve close collaboration with the Git migration team to develop Fab scripts tailored for repositories as they transition to Git. These scripts will serve as reusable templates for other sites within the Momentum Partnership, enabling them to efficiently port their own repositories. Additionally, BoM may introduce new features to Fab to accommodate specific requirements from various suites.
