Bauer Spezialtiefbau’s subsidiary Thai Bauer has announced that it has started work on foundations for the One Bangkok development in Thailand.
Thai Bauer will deliver 700 piles and 466m linear length of diaphragm wall for the new “city within a city” complex that spans over 16.7ha in the centre of Bangkok.

When complete, the Bangkok One scheme, which is being developed by Frasers Property and TCC Assets, will feature five office towers, five luxury hotels, three residential complexes, multiple retail zones, with space for arts and culture.
With a total gross floor area of 1.83M.m², One Bangkok is the largest private sector property development initiative ever undertaken in Thailand.
The bored piles being undertaken by Bauer have diameters of 1,500mm and 1,800mm and extend to depths of up to 80m and the diaphragm wall will extend to 35m depth. Bauer was also commissioned to undertake the preliminary pile load tests.
“The biggest challenge for Bauer lies in the fact that the construction site is right in the middle of pulsating downtown Bangkok,” said Thai Bauer managing director Mike Sinkinson.
One of the challenges for the site team is managing transportation of the excavated soil away from the construction site by trucks, which is restricted by traffic and city regulations. “In order to avoid delays and keep all adjoining roads free of contamination, we have installed special tyre washing facilities on site,” said Sinkinson.
In addition to handling logistics for the removal of the excavated soil, the constant supply of the construction site with concrete and steel for the bored piles is also calling for careful management. “In order to minimise the impact of the construction activity on nearby road traffic, concrete batching plants have been set up on the construction site itself,” added Sinkinson. “This allows us to continue working irrespective of traffic flow.”
At peak times, around 1,000m³ of excavated soil will be removed daily and up to 850m³ of concrete directly processed.
Thai Bauer expects to complete its work by April next year and One Bangkok will be completed in phases between 2022 and 2025.
