Scottish hydro power: Excavations in rock….The role of the Engineering Geologist

Renewable energy may be a hot topic at the moment, but it is far from being a new concept.  During the 1950’s and 60’s, large teams of workers and engineers were involved with the design and construction of numerous complex and fascinating hydroelectric engineering schemes.  As a result of these schemes, rainwater falling over 10% of the land mass of Scotland can now be used for the generation of electricity.  With the recent surge of interest in renewables, including run of the river hydro schemes, this catchment area is only likely to increase.

However, as with any major long-term asset, the safety and lifespan of these schemes is reliant on stringent inspection and maintenance regimes, including over 500km of tunnel and aqueduct, and many large rock faces.  Inspections of large rock faces and unlined tunnels through rock are undertaken by engineering geologists experienced in the assessment of rock slope and tunnel stability.  If required, the engineering geologist will recommend and design suitable risk reduction measures and will work closely with a specialist contractor during the implementation of any works.
