2 Bridge Construction East Tsing Yi Visduct (2004 to 2008) Technical information: Construction of an approximately 1.1 km dual 3-lane carriageway predominantly of pre-cast box girder segmental viaduct connecting the Stonecutters Bridge and the Nam Wan Tunnel in the south-eastern part of Tsing Yi Island. Associated works include the viaduct ramps, roadworks, drainage, slope works, landscape works and environmental mitigation measures. The viaduct comprises 18 pre-cast segmental bridges, for which there are a total of 1,939 re-cast segments and 51 in-situ segments on pier. Most part of the bridges have been designed to be erected with the balanced cantilever construction method. One of the greatest advantages of the balanced cantilever construction method over other erection techniques is its ability to effectively ensure that the moment induced in the piers at the time of construction is minimal. Tunnel Construction KCRC West Rail Kwai Tsing Tunnels (1998 to 2001) Technical information: The contract was won on the basis of an alternative design , which proposed the use of a mixed ground Earth Pressure Balanced Tunnel Boring Machine (EPBM) for part of the excavation. Use of the TBM avoided the need for a cut and cover section in a busy urban area, thus minimising disruption to the community. The 8.6 m diameter TBM, supplied by NFM Technologies, is the largest to be used in Hong Kong and the first equipped to excavate in mixed ground conditions. The TBM excavation was completed successfully ahead of schedule. Ocean Park Funicular Tunnel (2006 to 2008) Technical information: A 1275 m of single tube tunnel with gradient 9% straight tunnel connecting the lowland and summit by drill and blast method which comprised 134m of soft tunnel at South Portal Foundation Auger Piling Foundation for high-rise buildings

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
