<\/span><\/div>\n\n\n\nA 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\n\n\n\nLocated 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>\nHF8G\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><\/div><\/div><\/div><\/div>\n\n<\/div><\/div><\/div><\/div>\n<\/div><\/div>Innovation Award<\/p>\n

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>\nTo 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>
