Bauer provides further foundation engineering work for Bhutan hydro plant

5 March 2020

Bauer Spezialtiefbau GmbH has been contracted by Jaiprakash Associates Limited to carry out specialist foundation engineering work for the Punatsangchhu-2 hydropower project in Bhutan following the collapse of an underground cavern at the project.

Bauer’s engagement on the project follows earlier work in 2014-15 where it executed injection work to seal the project’s upstream cofferdam. 

The new contract instructs Bauer to carry out 18,000m of soil injection for subsoil stabilization as well as install 19,000m of tie-back anchors. Along with various equipment for the injection work, up to five drilling rigs are being used at the same time, including KR 806 and KR 909 rigs from KLEMM Bohrtechnik GmbH. 

Bauer's work on Punatsangchhu-2 will take around 15 months.
