Seth – Sociedade de Empreitadas e Trabalhos Hidráulicos was founded in 1933 by Danish company Højgaard & Schultz a/s (current MT Højgaard Holding), which decided to establish itself in Portugal after the construction of the Port of Setúbal.
Over its 91 years of history, Seth has successfully completed numerous building and infrastructure construction projects in Portugal and several African countries.
Having positioned itself as an innovative enterprise, Seth was awarded a contract to build the Marechal Carmona Bridge, in Vila Franca de Xira, in 1947. This was Seth’s first big project, based on an alternative construction solution developed and proposed by the company.
Innovation remains the image of Seth, which spares no effort to develop new solutions, focusing on collaboration to adapt them to its clients’ projects and expectations.
Seth has developed a wide range of projects and continues to operate in Portugal (including the Azores and Madeira), Angola, Algeria, Bermuda, Cape Verde, Gibraltar, Guinea, Guinea-Bissau, Iceland and Mozambique.
