Studio Ing. G. Pietrangeli S.r.l. (Studio Pietrangeli - SP)
Studio Pietrangeli (SP) was founded in 1964 by Giorgio Pietrangeli to provide specialised engineering services for large dams and hydropower plants.
The firm’s services cover all phases of a project and range from conception to monitoring during operation, including all the design activities, specialised studies, investigations, supervision of the works, and so on.
Although their core activities concentrate on dams and hydropower plants, they also specialise in large civil structures (tunnels, roads, etc.) and large hydraulic works (water supply systems, irrigation plants, ports, etc.).
Studio Pietrangeli’s staff of approximately 80 people includes internationally renowned experts, engineers and other professionals and technical staff specialised in the various project sectors. While SP’s head office is in Rome, the firm also has branches in Sierra Leone, Ecuador, Tanzania and Ethiopia and elsewhere sets up its own temporary premises and/or makes use of local partners’ facilities.
Their extraordinary domestic and international experience confirms the outstanding quality of their work. Studio Pietrangeli has successfully completed the design of over 160 dams, 60 hydropower plants, 250 km of hydraulic tunnels plus several irrigation, water supply and sewage treatment plants.
Alongside its more traditional engineering schemes, Studio Pietrangeli, from its beginnings, has always proposed innovative solutions to complex technical problems.
The firm is responsible for the engineering of several important international works recently completed or under construction. Those recently completed include Beles 460 MW, Gibe II 420 MW and Bumbuna 1st Phase 50 MW, while their two record-breaking projects under construction are Gibe III (world's highest RCC dam, 240 m)and Grand Ethiopian Renaissance Dam (6000 MW). Several Studio Pietrangeli 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, cited in encyclopedias (Wikipedia) and used to illustrate banknotes (Sierra Leone), rechargeable phone card and bound issues (Ethiopia).
Nowadays, many of the firm’s projects are conceived in only a few weeks through the adoption of so-called “fast track” techniques using satellite imagery, helicopter surveys, surface geotechnical investigations, with the result that several of their largest hydropower projects have been implemented in only four years from conception to operation.
Studio Pietrangeli's specialists are used to working in all types of conditions, from roughing it in field camps in African forests to attending official meetings with the highest echelons of government, industry and finance. Their passion for their work never changes.
Their engineers are accustomed to presenting their projects to clients of all types. They have even created simple effective presentations using cartoons and laymen's terms.
