After more than four years’ work, the PBJV Joint Venture (Penta Ocean, leader, Bachy Soletanche Singapore, and Soletanche Bachy International) has completed the tunnel diaphragm wall of the NSC 105 tunnel. This milestone marks a significant step forward in Singapore’s North-South Corridor urban highway project.
Technical challenges met by the the HF8G® with grippers
The teams overcame numerous technical and geographical challenges in Singapore’s densely populated Novena area, close to a Mass Rapid Transit (MRT) tunnel. The use of Hydrofraise® with grippers and roller bits minimized vibrations and maximized safety,
In 2023, Bachy Soletanche Singapore was awarded the Soletanche Freyssinet Innovation Prize for the Hydrofraise® with grippers and roller bits. Congratulations to François Pannetier, Roy IP, Bruno Launay, Andrea Aguilera, Laurent Pivert, Zen Chua and Renil Rabert Kennadi!
To salute the construction of tunnel’s diaphragm wall, an event was held with special guests, Mayor of Central District Ms. Denise Phua Lay Peng, and LTA DCE Mr. Chong Kheng CHUA, joining us in celebrating the completion of diaphragm wall construction for the NSC N105 project, achieving an impressive 8.37 million Lost Time Injury (LTI)-free hours. Overall, the project is over 43% complete and continues to progress.
