Underground construction works in urban area is always a challenge for development/redevelopment.  In particular the congested underground utilities, traffic conditions, public concerns and proximity to structural foundations.  Complicated underground geological conditions also present significance difficulties when dealing with the tunneling works.  This talk will cover the successful experience of the adoption of using a Rectangular Tunnel Boring Machine (RTBM) for the trenchless construction at Kai Tak Developments.
