Dam & Hydropower Engineers
We provide outstanding engineering services for dams, hydropower, hydraulic projects and transmission lines. We have designed several renowned plants such as Gibe III, Grand Ethiopian Renaissance, etc.
Fifty years of innovative engineering
Studio Pietrangeli was founded in 1964 by Giorgio Pietrangeli and, since then, has been a leading firm for dams and hydropower.
The firm’s services cover all phases of a project, from conception to monitoring during operation. We carry out all the design activities, studies, investigations, supervision of the works, and so on.
Although our core activities focus on dams and hydropower plants, we are also specialised in large civil structures (tunnels, roads, etc) and large hydraulic works (water supply, irrigation plants, etc).
Studio Pietrangeli’s staff of approximately 80 people includes internationally renowned experts, engineers, geologists and other professionals and technical staff.
While Studio Pietrangeli’s head office is in Rome (Italy), the firm also has branches in Sierra Leone, Tanzania and Ethiopia and elsewhere sets up its own temporary premises and/or makes use of local partners’ facilities.
Our extraordinary international experience confirms the quality of our work. SP has successfully completed the design of over 200 dams and 30'000 MW of hydropower plants in more than 30 countries.Alongside its more traditional engineering schemes, Studio Pietrangeli has always proposed innovative solutions to complex technical problems.
The firm has invented several record-breaking projects: the world's highest RCC dam (Gibe III, 250 m), Africa's largest hydropower (GERdp, 6000 MW), Africa's longest hydraulic tunnels (Gibe II, Beles, 25 km). Several of our projects, given their innovative solutions and importance, have been written about and/or cited in prestigious magazines such as National Geographic, International Water Power and The Economist.Our dams were used to illustrate banknotes (Sierra Leone), as a re-chargeable phone card and for bond issues (Ethiopia).Our innovative technical solutions are described in renowned books, such as Prof. Hoek's "Practical Rock Engineering".
