India - BAUER Engineering India Private Limited, a subsidiary of BAUER Spezialtiefbau GmbH, has been commissioned by Jaiprakash Associates Limited to carry out special foundation engineering and geotechnical work for the Teesta VI Hydro Electric project.

The project developer is M/s. Lanco Teesta Hydro Power Limited, a wholly owned subsidiary of the National Hydro Power Corporation of India. The project will be realized in the city of Singtam on the Teesta River. This more than 300 km long body of water rises from the Pahunri Glacier above 7,000 m in the eastern Himalayas and flows through the Indian states of Sikkim and West Bengal until it empties into the Jamuna River at Fulchhari in Bangladesh.

The services of BAUER Engineering India Private Limited include the construction of a back-anchored bored pile wall, consisting of approx. 10,000 lfm. Piles with a diameter of 800 mm and around 60,000 ml. anchor. The bored pile wall is intended to enable a 40 m deep excavation for the inlet structure on the right bank. Along the upstream cofferdam, a 4,700 m-2 sealing wall will be erected using the nozzle blasting process, and 4,600 m-2 of diaphragm wall will be produced on the upper water side of the barrage in two individual phases. For the work in the rocky alluvial land, a diaphragm wall milling machine is used after preliminary work.

'Due to the special location of the Teesta River, it is proving challenging to harness hydropower while protecting residents from flooding,' said Harish Agarwal, Senior Vice President of Jaiprakash Associates Limited. In addition, there is the limited space on the construction site due to the relatively narrow valley and the steep slopes as well as the work in the immediate vicinity of the existing barrage. The construction work will also be carried out in an area with considerable scree layers and irregular flooding.

Bauer began work in April this year and is expected to complete it in autumn 2024.
