Environmental monitoring, modelling and assessment works on High Speed 2, Europe’s largest railway infrastructure project

A major high-speed railway project across the UK

High Speed 2 (HS2) Phase 1 is a large high-speed railway project in the United Kingdom which will link London and Birmingham, with a future second phase to reach Manchester and Leeds in Northern England.

This major project will provide increased capacity and reliability of the railway links and should help manage the rising number of passengers.

HS2 phase 1 is expected to open to passengers in 2026 and Phase 2 around 2033.

 

Sixense expertise applied to this environmentally challenging major project

Sixense is excited to embark on the significant challenge of providing noise, vibration and air quality management services on a section of Europe’s largest infrastructure project, HS2. This section of the mega engineering project, delivered by Align JV, includes the route’s flagship 3.4km-long Colne Valley Viaduct, as well as the 15.8km-long Chiltern twin-tunnels. The services to be provided by Sixense include a significant amount of monitoring, modelling and assessment work across the 10+ worksites, which will play a key role in the wider efforts to minimise environmental impacts throughout the 5-year build.

 

Sixense teams providing efficient solutions

Within the first six weeks of its involvement, Sixense already installed 22no. noise and air quality monitoring stations, which are largely powered by sustainable-energy sources.
