Because of the growing population, it has become necessary for the city to find a way to permanently ease road traffic and create a public means of transport. In 2004, the subway system Bangkok Metro (MRT) opened under the supervision of the Mass Rapid Transit Authority of Thailand (MRTA). The existing metro lines, which are marked with the colors blue and purple, cover 35 stops over a distance of about 28 miles. Current expansion for these existing lines is underway, as well as construction on another line - the MRT Orange Line. In the future, the new line will complement the existing MRT network and provide a link between the eastern suburbs of Bangkok and the city center of the metropolis. Specialist foundation engineering works for the MRT Blue Line, Purple Line, and Green Line extensions is being conducted by Thai BAUER Co. Ltd., the Thai subsidiary of BAUER Spezialtiefbau GmbH. Thai BAUER was also recently commissioned by the contractor, the Joint Venture Ch. Karnchang - Sino Thai, to carry out various specialist foundation engineering works for the construction of the new metro line. More than 370 bored piles are being drilled to a depth of 130-210 feet, and approx- imately 192,000 square feet of diaphragm wall are being constructed down to a depth of 88 feet. In addition, during the rainy season, the stability of the subsoil and access to the site need to be ensured. Works started in March 2018, and the completion of Thai Bauer’s specialist foundation work was planned for this spring. Completion of the new Orange Line is expected to take place in 2022. “The challenges of this project are diverse,” said Mike Sinkinson, managing director of Thai Bauer. “First of all, extremely stringent tolerances for the installation of the bored piles have to be kept, while work is required to be carried out above existing tunnels, so great care and accuracy are essential for the success of this project. Also the logistics between the steel processing locations and the respective application areas must be regulated and access to the construction site via the main road must always be available.” Thai Bauer executes various specialist foundation engineering works for the new MRT Orange Line in Bangkok.
