We supported the environmental operations for the construction of a railway line

Prior to the construction of a new underground railway line in Delft, Netherlands, a large quantity of soil needed to be moved. The railway tunnel cuts directly through the city center of Delft and runs past several historic monuments and buildings—which put an emphasis on quality craftsmanship and effective construction methods.

After consulting with ProRail—the Dutch railway management organization—it was decided to have the project certified according to the Dutch Soil Regulatory Guideline for large-scale projects with soil excavation (BRL 9335). BRL 9335 encompasses a set of processes to support reliable, environmentally-sound soil qualification that will boost efficiency and yield significant cost savings.

With the soil certification process, careful construction techniques, and an online subsurface model that monitored the excavation, our team was able to customize an extensive, multifaceted solution. We helped our client produce the new railway tunnel safely and effectively, connecting the city of Delft to all major rail networks in the country. The project was completed in partnership with consortium Combinatie CrommeLijn.
