The SMART (Stormwater and Management Road Tunnel) project is a 9.7 km single-bore tunnel to divert Ampang river waters which cause stormwater overflow during the rain season. The tunnel will head for south of Kuala Lumpur following Jalan U Thant, Jalan Tun Razak, Jalan Chan Sow Lin and the Seremban Highway parallel to the old military airport. Wayss & Freytag and BAM NBM of the Netherlands won a 5.4 km section of it for €83 million from the client, contractors Malaysian Mining Corp. (MMC) and Gamuda. A Herrenknecht Mixshield TBM will be used, cutterhead diameter 13.21 m, inner diameter 11.83 m, concrete segments 500 mm thick. The TBM is under manufacturing at the moment for arrival in Malaysia scheduled for around Christmas. Delivery in Kuala Lumpur is planned for end-January. A three-month pre-assembly period will follow prior to excavation start expected in mid-May 2004. In the central part of the tunnel is a 2.4 km-long stretch with a dual purpose for flood mitigation and road traffic on 2 levels. The third level will accomodate utilities, ventilation, etc. The 5.4 km tunnel section awarded to Wayss & Freytag and BAM NBM includes 700 m of dual function. Visit www.wf-ingbau.de and www.bamnbm.nl The remaining 1.7 km for double function is part of the 4.3 km north tunnel section that will be built by Malaysian Mining Corp. (MMC) and Gamuda using a second Herrenknecht Mixshield TBM, also under construction. Visit www.mmc.com.my and www.gamuda.com.myTwo junction boxes are at either end of the dual-purpose 2.4 km stretch with 2 ventilation shafts in between. Kecom Sdn Bhd, the Malaysian branch of KEC Ltd of Korea, is one of the tenderers negotiating the supply of precast concrete segments worth RM100 million for the project. Visit www.herrenknecht.com 24/03.ACP Industries (ACPI) said its unit Associated Structural Concrete Sdn Bhd has won a RM51.2 million contract from Wayss & Freytag to supply precast concrete segmental lining for the stormwater management and road tunnel (SMART) project. The contract is for about 33 months. 32/03.Tuah, SMART's first 13.21 m-diameter slurry TBM, has begun boring on 4th June. Tuah spans about 70 m in length and weighs a hefty 2,500 tonnes. The Herrenknecht machine will be boring towards the north of the tunnel alignment, ending at the holding basin in Kampung Berembang. The name Tuah was selected through a naming competition launched in March. 95% of the tunnelling will be done using two TBMs with the rest by way of cut-and-cover method. The yet-to-be named second TBM is being assembled in the launch shaft, for boring start in August.
