On November 16, the TBM operated by our teams on the Pawtucket tunnel site, in the United States, began its excavation. This dual-mode earth pressure balance and open-mode tunnel boring machine, with a diameter of 10.3 metres and a length of 105 metres, will lay a total of 1,722 rings. It will dig a 3.5-kilometre tunnel along the Seekonk River, which will store the region's stormwater, wastewater and industrial water.
Congratulations to the teams!
Why This Tunnel?
To keep the Bay and local waterways clean from stormwater runoff. The Restored Waters RI project is designed to capture this stormwater runoff that has been dirtying local waters for many years and send it to the Narragansett Bay Commission treatment plant.
Digitalisation
On site, the teams implemented the digital tool QuickConnect in order to increase productivity and reliability. Thanks to this tool and the support of the #AllConnected team, the project has digitised several processes, including: the publication of daily reports, the monitoring of the prefabrication of segments, and the automatic analysis of concrete inspection reports. A common interface for reading the data was created, allowing the various players on the site to access the same data and to benefit from real-time progress monitoring, assistance in managing the schedule, and also a file of executed works realised progressively... in short, digital technology to simplify.
