PowerHouse: Design discharge hits two Pelton turbines with a capacity of 118 MW. The water is then discharged into the reservoir of Mangdechhu Hydropower Project
The complete instrumentation & monitoring work for the Dam, Power House, and Head race tunnel project was awarded to Encardio-rite. The scope of work included:
The instrumentation consisted of hundreds of geotechnical sensors including:
An automatic Data Acquisition System was installed and commissioned to collected data from the above geotechnical instruments. The data was collected automatically at required intervals.
Encardio-rite provided a comprehensive monthly monitoring report, combined for geotechnical and geodetic monitoring data on a weekly and monthly basis. Monitoring reports included interpretations of variations observed in instrument data with respect to the construction progress in the respective area.
