Sociedad Anónima Trabajos y Obras is a construction company that has been working on top level projects for over eighty years, always standing out for its technological innovation capability and its project quality.

In 1927, construction of the new Las Palmas port was adjudicated to “Koninklijhe Nederlandsche Maatschappij Voor Havenwerken N.V”; in 1935 this company was set up with entirely Dutch capital as “Sociedad Anónima Trabajos y Obras” (SATO) to continue its construction business concerning public works in Spain. Dutch shareholder participation was progressively reduced and its capital has been entirely Spanish since 1973.

In 1997, practically all its capital was bought out by Sociedad General de Obras y Construcciones (OBRASCON). Successive mergers took place in this company to absorb Huarte and Construcciones Lain, making it the sixth largest Spanish construction group.

SATO has worked as a general construction firm throughout its history, but right from the outset it always leaned towards and specialized in maritime projects. Inclusion in OHLA makes it the group benchmark for maritime jobs and helps them take on complex projects for major accounts, from the initial project to its actual execution, commissioning and operation, in all port and coastal fields, even in privately financed projects.

SATO has a significant floating machinery stock, doubtlessly one of the most complete sets of equipment in Spain, helping it lead the way in national maritime projects. This machinery stock is strengthened by agreements with international construction companies, leaders in their respective fields, to cover the needs of any type of coastal and port job.

Its leadership in the Spanish port sector has given SATO a seat at the table in the most important projects in different ports all around Spain, highlighting SATO’s contribution to Extending the Port of Gijón and the new facilities at Punta Langosteira (A Coruña), both port jobs with a major investment budget up for tender, in the Port of Granadilla (Tenerife), Barcelona South Dike, Port of Alicante, Port of Algeciras, Port of Cádiz, etc., currently attaining a portfolio of almost 400 million Euros.
