Thai Bauer carries out specialist foundation engineering works for Bangkok’s MRT Orange line
With space tight in urban environments, it is often necessary to have transport links underground, such as in Bangkok, Thailand, with the expansion of the Bangkok Metro (MRT).
The existing metro lines, which are marked with the colours blue and purple, cover 35 stops over a distance of 45km. In addition to the current expansion of existing lines, another line is now under construction: the MRT Orange Line.

As well as having undertaken specialist foundation engineering works for the numerous line extensions, Thai Bauer was commissioned to carry out specialist foundation engineering works for the construction of the new metro line.
More than 370 bored piles with diameters of between 800 and 2,000mm are being drilled to a depth of between 40 and 65m, and approximately 58,600m² of diaphragm wall with a width of 800 to 1,000mm are being constructed down to a depth of 27m.
“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.”
The completion of the new Orange Line is expected to take place in 2022.
