Construction principles

The River Thames Scheme (RTS) is a major project of national significance, and we recognise that there will be impacts during construction. It is important to us that we prioritise being considerate constructors, minimising disruption to the community and prioritising safety, environmental responsibility, and respect for residents throughout the construction process.

During the construction process, we are focused on maximising the environmental benefits of the scheme and minimising the negative effects. This is why the scheme is committed to material management principles where we plan to reuse and recover significant amounts of material and waste within the scheme to help the scheme achieve its design sustainability benefits.

Our approach to construction management

This approach will see us register with the Considerate Constructors Scheme and agree to abide by a Code of Considerate Practice.

Our construction programme

Refer to our development consent order page for further information on the construction timeline.

Enabling works

The initial phase before starting the main construction involves extensive preparatory work, including our comprehensive survey work, environmental assessments, our ongoing engagement with landowners, and setting up construction areas and site accesses. These activities are crucial for ensuring that the construction process is as smooth and efficient as possible, laying the foundations for the construction works.

Main engineering works

The main engineering works include the construction of the new flood channel in two sections, and the capacity improvements to existing river structures, lowering the riverbed downstream of the Desborough Cut. The construction process will involve significant activities and take around four years to complete. To note: the flood relief channel won't be used for flood purposes until the downstream capacity improvements are finished and operational.

The RTS expect to appoint a construction partner in Autumn 2025, refer to our supply chain page for further updates.

Ecological and green space enhancements

In parallel with the engineering works, the scheme will focus on creating and enhancing green open spaces and developing active travel routes. This includes the development of the new recreational areas and wildlife habitats. These construction activities will be carefully managed to protect existing ecosystems and integrate the new green infrastructure seamlessly into the landscape.

Mitigating environmental impact

The scheme has been monitoring many environmental aspects of the waterways and land for several years to better understand the potential environmental effects.

A key priority during, and beyond, the construction phase of the RTS is minimising environmental impact. This involves implementing measures to protect wildlife, reduce water and air pollution, and manage the waste effectively. The scheme will closely monitor our carbon footprint in relation to the construction, and so will incorporate the use of sustainable construction practices, such as using low carbon construction materials and energy-efficient design principles to minimise the scheme's effect on the climate.

Community engagement and communication

Throughout the construction phase, maintaining open lines of communication with local communities is essential. Regular updates ensure that residents are informed about the progress and any potential disruptions. This engagement helps to address concerns promptly and respond.
