To ensure The HS2 Project Teams had technical advice, support on geospatial procurement, management and suitable analysis which supported temporary works drainage design and flood risk for the HS2 Project for Section C2 and C3 (85 km) of the High Speed 2 (HS2) railway project. Which included safeguarding of groundwater environmental receptors over 3,600 km2.
The team at Síor Consulting Ltd developed an efficient and accurate process of geospatial analysis and modelling, including development of a detailed Digital Elevation Model for hydrological characterisation including definition of storm run-off routes, catchment areas and coefficients. Through development of a GIS based Collectors App, data could be verified in the field and shared seamlessly back to our model environments. Síor Consulting produced drawings and a series of geospatial software products including 3D flythough videos and WebApps to share findings directly with the client.
To support informed decisions to minimise HS2 temporary works impact on the environment.
