Penta-Ocean entrusted us with a challenging project involving the installation of multiple utility pipelines within the MRT protection zone. The project required the use of the pipe sleeve mining method to install 6 sets of lead-in pipes, including telecom and electrical pipes. The work was conducted under extreme soil conditions, making the mining process particularly difficult. Additionally, careful measures were taken to avoid surface excavation, ensuring that bus lane operations continued without disruption and pedestrian safety was maintained in a high-traffic area.
