DESCRIPTION
This presentation was given as part of a site visit to the Kwun Tong line extension in Hong Kong on the morning of Saturday 25th October 2014. The visit was organised between the APM HK branch and the Nishimatsu Construction Company ltd. This was an opportunity to see the progress of the Kwun Tong Line Extension (KTE). The current railway network has not covered some of the more densely populated areas such as Ho Man Tin, Hung Hom and Whampoa. Additionally, the frequent traffic jams from the Cross Harbour Tunnel during peak hours cause great inconvenience to commuters. The Mass Transit Railway (MTR) Corporation has long been planning to launch the Kwun Tong Line Extension project (KTE) to alleviate the serious traffic congestion. MTR was authorised to proceed with the project in 2010 and the construction of the new rail line commenced in 2011. The alignment of KTE will be extended from the existing Yau Ma Tei Station to Whampoa via Ho Man Tin with 2 new stations to be built. The contract of construction of the new Ho Man Tin Station and a tunnel from Yau Ma Tei to Whampoa was awarded to Nishimatsu Construction Company Limited. Meanwhile the Chun Wo – Hip Hing joint venture is in charge of the construction contract for Whampoa Station and overrun tunnel. The project is currently underway at a cost of around HK$5.3 billion (in December 2009 prices). This site visit will take you to see the Ho Man Tin Station construction work, followed by the Yau Ma Tei to Whampoa Tunnel, HMT Station cavern and a general view of the tunnelling and station (which has been formed within the cavern area) works.
