The project is one of the major construction contracts of a new cross-boundary connection in Hong Kong between the boundary control point near Heung Yuen Wai and Fanling Highway to provide a strategic and direct new transport link to serve the cross-boundary goods vehicles and passengers travelling between the northeast New Territories and Shenzhen East on Mainland China. Atkins is employed by Dragages (Hongkong) Limited to be the design consultant firm for the detailed design of a 4.8-km-long dual two-lane Lung Shan Tunnel excavated by tunnel boring machine (TBM) and Drill-&-Blast techniques, mid-ventilation adit, and temporary site formation at portals with other associated works.
One of the key challenges for Atkins is to carry out the detailed design of 12.5m ID TBM permanent lining for double tube tunnels in various ground conditions and form a numbers of underground cross passage openings with 6m span in soft ground underneath public area with shallow ground cover.
