Costain, the infrastructure solutions company, has announced that it has been awarded an extension to its existing Service Partner Framework contract with Network Rail. The twelve-month extension will run until the end of January 2025 and is expected to be worth more than £5 million. Under the contract, Costain will provide Network Rail with specialist project-management, planning, and risk-control services across various programs. This includes supporting Network Rail's Weather Risk Task Force, which aims to mitigate the risks of climate change to the railway, such as landslips and flooding.
