Work started in mid-Dec. 1999 on a 40.8 km U-shaped light rail line in the Chinese capital, Beijing. The $707.8 million line has been designed to relieve traffic congestion, improve air quality, and stimulate the property market in various districts. The line, with 30.3 km at grade, 7.7 km elevated, and 2.8 km in tunnel, will cover north Beijing, running from Xizhimen in the northwest to Huilongguan in the northeast. After completion, which is scheduled for 2001, the line will be extended from Huilongguan to Dongzhimen by 2006. It will provide interchanges with the city's circular metro line at Dongzhimen and Xizhimen. February 2000.

The twin 1.8 km-long Pak Shing Kok tunnels are under construction using drill & blast. Meyco reports three Spraymobiles in use successfully building 250 mm shotcrete layer in one pass using Meyco SA160 alkali-free accelerator with Sika LA400 superplasticiser. More from www.mbt.com January 2000.

Visit www.transfield.com.au 11/01.International competitive bidding (tender notice No. 10/WSD/07), deadline 30th November, 2007 for the ground investigation works for Inter-reservoirs Transfer Scheme (IRTS), water tunnel between Kowloon Byewash Reservoir and Lower Shing Mun Reservoir. The scope of the project comprises the construction of a water tunnel, approximately 2.8 km in length and 3 m in diameter, and the associated intake and outfall structures at both ends of the tunnel. The geology of the area basically comprises of mainly granite. At the portal, contractors will make use of conventional mechanical excavation (hydraulic hammer and backhoe). The main tunnel will be built by a tunnel boring machine. The temporary support depends on rock mass quality (envisaged support may include rock bolts, welded wire mesh, steel arches and/or shotcrete). As permanent support lining, the tunnel may be partly unlined subject to development of hydraulic design but permanent rock bolts will be anchored in unlined portions whereas in lined portions, cast in-situ lining or shotcrete will be preferred (with adequate finish for optimal hydraulic roughness). In the main tunnel, a conveyor belt or mining train with wagons will be used to transport the rock away. The project is still in preliminary design and bids for construction are expected to be invited in July 2009. Work is scheduled to start in December 2009 for completion in April 2012. The cost of the tunnel is HKD220 million. Contact Water Supplies Department, Hong Kong, tel. +852 28294798, fax +852 25861696, e-mail Ricky Wong Kin San ricky_ks_wong@wsd.gov.hk.

The Drainage Services Department (DSD) signed a EUR496,37 million (HK$763 million) contract with Bouygues Travaux Publics in Hong Kong to build the Inter-reservoirs Transfer Scheme between Kowloon Byewash Reservoir and Lower Shing Mun Reservoir in Kowloon. The works include construction of a water tunnel of about 2.8 kilometres with 3 metres diameter from the Kowloon Byewash Reservoir to the Lower Shing Mun Reservoir and the associated intake and outfall structures at both ends of the tunnel.  When completed in 2022, the tunnel will serve dual objectives of improving flood protection level in West Kowloon areas and optimising water conservation, by transferring collected surface runoff from the Kowloon group of reservoirs to the Lower Shing Mun Reservoir.This 38-month works contract commenced on 27.02.2019.

  Kier Hong Kong Ltd in jv with Penta-Ocean Construction of Japan awarded $225 million contract to construct Tsuen Wan station for Kowloon-Canton Railway Corporation (KCRC). Station box will be constructed on reclaimed land within a diaphragm wall cofferdam 400 m-long x 40 m-wide x 15 m-deep and approach tunnels will be cut and cover protected by diaphragm walls. In total, over 2 km of diaphragm wall up to 28 m-deep will be required. Excavation involves removal of some 500,000 cu m of material and construction will require 225,000 cu m of concrete. Kier is already working in jv with Zen Pacific for KCRC to construct the $160 million Mei Foo station. January 2000.  French manufacturer NFM reports the launch this week of its new 8.5 m-diameter EPB on a 1.8 km drive for the Dragages/Zen Pacific joint venture at the West Rail project. The machine is the first EPB to be deployed in Hong Kong, and is also the largest TBM to enter service in the territory to date. It was designed by NFM under licence from Mitsubishi and was manufactured in Shanghai. It is equipped with both screw and belt conveyors and a rotating segment erector, and will build an average 11 m/day of 7.6 m i.d tunnel in mixed ground. It is scheduled to complete the first tube in six months and will be dismantled and returned to the launch shaft for the second tube which should be completed 15 months from now.
