Fewer cars on the road during the summer months – but the work doesn’t stop ! OPTIMUM engineers were alongside SADE on the main road between Lille and Tourcoing for the completion last week of an auger boring crossing beneath the tramway lines.
This DN 1000 crossing will enable Lille metropolitan authority (Métropole Europénne de Lille) to reinforce the region’s drinking water network – essential infrastructure for long-term sustainability.
The works were carried out on behalf of Métropole Europénne de Lille, with project management by SOURCEO.
Prior to drilling, OPTIMUM’s calculation and modelling experts determined push forces, load resistance, as well as the appropriate entry / exit pit dimensions for the project. This was able to be done swiftly, thanks to in depth geotechnical knowledge of the region.
OPTIMUM’s trenchless engineers was then onsite during the construction of the 47-metre-long crossing. Working within the confines of the urban area, SADE built the retaining structures – steel sheet piling on entry, slide rails at the exit – and FNO the crossing itself.
After just a fortnight on site, the job is complete.
