BAUER SPEZIALTIEFBAU is piling the foundations for the final section of a new road in Bangkok which aims to reduce severe congestion in the Thai capital.
The firm is working for main contractor Vichit Phan Construction Company. Its six month contract will see piles installed for Section S1 of the Third Stage Expressway System, which will extend the Bangkok to Chonburi Highway and link to the Ramindra-Ardnarong highway in the north east of the city.
The elevated deck is being built above the existing road, so much of the piling had to be carried out from the central reservation - in some cases providing just 6m of working area. This meant mobilisation of all plant and equipment and deliveries of steel reinforcement and concrete had to be carried out at night.
As almost everywhere in Bangkok, adequate load bearing strata for heavy foundation loads are found only at depths of about 50 m or below. Work on five test piles started in September 2003.
The four BG rotary rigs began installation of working piles in the middle of November and will take a maximum of six months to complete.
