Another milestone reached on the NSC 105 project: completion of the cast tunnel wall<\/h1><\/div>
<\/div>

After more than four years’ work,\u00a0the PBJV Joint Venture, comprising Penta Ocean (leader), Bachy Soletanche Singapore and Soletanche Bachy International,\u00a0<\/strong>has just completed the tunnel diaphragm wall of the NSC 105 tunnel, marking a turning point in the North-South Corridor urban freeway project.<\/p>\n<\/div>

This first phase of the project took place in several stages, during which the BU teams had to overcome numerous technical challenges. This latest achievement once again underlines the dedication and ingenuity of the project teams on site.<\/p>\n<\/div>

Challenges met by the HF8G\u00ae with grippers.<\/h2><\/div>

A total of 13,223 m\u00b3 of GIII, GII and GI rock has been excavated since the arrival of the HF8G\u00ae hydrofraise machine\u00a0with grippers\u00a0<\/strong>in 2021. A total of 5,225 hours of excavation were required to build the diaphragm wall tunnel.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Located in the densely populated Novena area of Singapore, with busy roads and buildings, BU used rigorous planning to minimize any disruption during construction. To achieve this, the teams used the HF8G\u00ae to reduce vibrations and enhance tool stabilization, thanks to its gripping module. This machine considerably improved the execution of the diaphragm wall.<\/span><\/p>\n

HF8G\u00ae was also deployed during work close to the IRAS building and an existing Mass Rapid Transit (MRT: high-capacity rail transport system serving the city-state of\u00a0<\/span>Singapore<\/span><\/a>) tunnel, located less than 4 meters from the diaphragm wall. Its use ensured minimum vibration and maximum safety.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>

Innovation Award<\/p>\n

\u00a0<\/p><\/h2><\/div>

In 2023, Bachy Soletanche Singapore was awarded the Innovation Prize for the Hydrofraise\u00ae with grippers and roller bits. The main team members honored for their contribution were Fran\u00e7ois Pannetier, Roy IP, Bruno Launay, Andrea Aguilera, Laurent Pivert, Zen Chua and Renil Rabert Kennadi.<\/span><\/p>\n

To celebrate the construction of the tunnel’s diaphragm wall, the subsidiary organized an event bringing together the mayor of Singapore’s Central District, customers, and stakeholders. The event was an opportunity to pay tribute to the collaborative efforts of all those involved in the project.<\/p>\n<\/div>

\u00c0 ce jour, le projet est achev\u00e9 \u00e0 43 %.<\/strong><\/span><\/p>\n

Where are we with the project<\/strong>?<\/span><\/p>\n

Today, the subsidiary’s attention is focused on the excavation of the shaft in preparation. Bachy Soletanche Singapore plans to use the SFT ( Safe Faceless Tunneling) method for the project. This innovative tunnel-building technique makes it possible to construct a tunnel without the need to excavate a face, i.e. without creating a large, exposed opening in the ground in front of the work.<\/span><\/p>\n

To date, the project is 43% complete.<\/strong><\/span><\/p>\n<\/div>
