China Railway 11 Bureau Corporation engaged us for a complex and high-stakes project involving the installation of a new sewer pipeline beneath major infrastructure. The project required the excavation of a deep shaft and sewer pipe jacking using a micro Tunnel Boring Machine (mTBM) under an expressway and flyover. The need to work beneath these critical transport routes made the project highly challenging, demanding utmost precision and advanced engineering solutions to avoid any disruption to traffic and ensure the stability of the overhead structures
