The bridge at Bombo Burn required extensive remediation in the form of scour protection works, as well as vegetation management and masonry repair works.
Structure UB162/002 located on the AYR4 023m 0880yds servicing the Bombo Burn, required extensive remediation in the form of scour protection works to lower the EX2052 risk scour score to 10 in addition to vegetation management and masonry repair works.
Story Scotland were commissioned by Network Rail to carry out the £500k worth of works. This included the installation and removal of a temporary damning system, the excavation and profiling of the riverbed and the installation of reinforced concrete invert and Rip Rap.
Through the maximisation of planned labour, plant and equipment during periods of excellent weather, the team were successfully able to mitigate any weather delays. Moreover, the early engagement with all specialist sub-contractors who worked collaboratively throughout the project enabled a smooth transition from task to task on the programme’s critical path.

The scope of the works involved:
The project was able to celebrate success
and demonstrated best practice within the
following areas:
Our project team worked in close collaboration with NWR,
environmental agencies and designers to ensure various
specialist works could be completed within the allocated time
frame for working within the watercourse, with solutions
such as an effective temporary damming system & ensuring
the works did not jeopardise the shallow foundations present
supporting the structure.
Our project team also effectively planned works and used an
innovative technology to enable the works to be planned and
implemented successfully in ever changing weather and water
level conditions
I would like to express my thanks and congratulations to everyone involved in this project. The client organisation is delighted with the successful delivery and very happy with the final product. We recognise that the timescales and the severe weather were extremely difficult to contend with and it is commendable that the scope has been achieved to such a high level of quality despite the significant challenges. I don’t need to re-emphasise the importance of scour protection schemes to the ongoing management of railway assets so I will simply say well done and excellent work.
