Overview
Edafos Engineering Consultants S.A. (Greek: ΕΔΑΦΟΣ ΣΥΜΒΟΥΛΟΙ ΜΗΧΑΝΙΚΟΙ Α.Ε.) is a Greek engineering consultancy based in the Plaka district of central Athens. Founded in 1993 by Spyros Kavounidis, a civil engineer from the National Technical University of Athens with a Ph.D. from Stanford University, and Giorgos Ntounias, a civil engineer from NTUA with a Ph.D. from Imperial College, the firm has built its reputation on geotechnical engineering and geology applied to civil infrastructure. Its services span the full project cycle: geotechnical and geological investigations and studies, static and structural design, pavement engineering, hydraulic and environmental studies, quality control, and consultancy services for construction supervision and operational monitoring of large technical works. The company operates from its own 460 m² office building in Plaka, Athens, and maintains a laboratory. Its project experience covers motorways, railways, the national road network, landslides and slopes, underground works, dams and reservoirs, foundations, building works, monuments, retaining structures and technical works. Over more than thirty years of operation, Edafos has maintained a continuous presence and substantive participation in the major infrastructure projects built in Greece, and it has established itself for the high level of services it provides in the field of studies and consultancy for the construction and monitoring of large infrastructure works. Edafos is staffed by a significant number of civil engineers and geologists. Its design departments hold legal licences for specialised software, and since 2009 it has operated its own laboratory facilities. The firm is privately held and is not listed on a stock exchange. Its client base and project portfolio are documented on its official website, which also publishes company information, balance sheets, publications and contact details.
History
Edafos Engineering Consultants S.A. was founded in 1993 by Spyros Kavounidis and Giorgos Ntounias. Both founders are civil engineers: Kavounidis graduated from the National Technical University of Athens (EMΠ) and holds a Ph.D. from Stanford University, while Ntounias graduated from EMΠ and holds a Ph.D. from Imperial College. The company was established to provide engineering studies and consultancy with a focus on geotechnical engineering and geology, disciplines that underpin the design and safe construction of major civil works. From its base in Plaka, in the centre of Athens, Edafos grew into a firm staffed by a significant number of civil engineers and geologists. It operates from its own 460 m² office building, equipped with full office facilities, and its design departments hold legal licences for specialised engineering software. In 2009 the company added its own laboratory, extending its capabilities into testing and quality control. Over more than thirty years of operation, Edafos has maintained a continuous presence and substantive participation in the large infrastructure projects constructed in Greece. Its portfolio of works includes motorways, railways, the national road network, landslide and slope stabilisation, underground works, dams and reservoirs, foundations, building projects, monuments, retaining structures and technical works. The company has established itself for the high level of services it provides in studies and in consultancy for the construction supervision and operational monitoring of large technical infrastructure projects. Edafos remains a privately held Greek company. Its official website documents its history, shareholders and board, study licences, personnel, equipment, policies, clients, balance sheets, services, laboratory, representative works and publications.
