AYESA begins in a modest office with two engineers and five employees. Its passion for innovative technology leads it to being awarded a contract to carry out the mathematical modelling work for Madrid’s water supply network, something which was cutting-edge and unique at the time, and which it completed with great success.


Now with a team of twenty employees, AYESA is a prestigious company and immerses itself in projects of great complexity, such as the enormous La Pedrera reservoir, which receives water from the Tagus-Segura water transfer, an earth dam in Spain’s area of greatest seismic activity.


The company carries out its first project abroad: the Santa Elena irrigation systems, in Ecuador, opening its first office here in Guayaquil. In this same year, Seville’s bid to host the 1992 world expo (EXPO 92) is successful and thirty AYESA technicians take part in building the vast majority of its infrastructure. Another milestone for the company this year is designing its first F1 track, in Jerez.


AYESA provides the technical brains behind the EXPO project in terms of its design and many other aspects. The Cachorro bridge, an example of beauty, stands out here. This same year, the company founds an ICT development facility company, years before the Internet appeared.


AYESA is awarded its first high-speed train contract for the Madrid-Barcelona AVE line. It is also awarded its first motorway project for the Pan-American Highway in Peru. This same year, it becomes the first Andalusian company specialised in implementing SAP. At this time, AYESA has 140 technicians, all based in Seville.


AYESA has been immersed in a process of international expansion for three years when it sets up its office in Mexico, a country which has since become key for the group. In Mexico, the Acueducto II Project is a real milestone in engineering. AYESA has now tripled in size.


The company acquires a Catalan chemical process engineering company, which joins the group, this marking AYESA’s debut in the industrial sector, an area in which it will subsequently gain an outstanding reputation in the yeast, pharmaceutical and oil & gas sectors.


A key year. Now with offices in Poland, Morocco and India, the company wins tenders for two emblematic projects in Latin America: line 2 of the Panama City metro and the Atotonilco wastewater treatment plant in Mexico City, the biggest in the world. AYESA opens its technological facilities branch in Mexico.


AYESA acquires a major technology consulting company specialised in public sector and electrical distribution solutions, with one thousand, seven technicians. This is a major milestone, meaning AYESA is now an ETC (engineering, technology, consulting) company. It also debuts in the aeronautical sector, being awarded its first contract with AIRBUS.


Supported by an outstanding R&D&i team, the company leads European research projects. It is awarded a contract by Netefficient to carry out energy efficiency work in homes. It also creates its own solutions for big data, electric car fleet management and losses on grids, as well as an extensive portfolio of cutting-edge technological applications.


The international nature of AYESA leads to its introduction in the English-speaking world. It opens an office in London and establishes contact with clients, financial entities, competitors and partners. Its longstanding presence in Spanish-speaking countries provides it with the backing and prestige it needs when seeking out partners.


AYESA’s position in eastern markets, namely Saudi Arabia, the United Arab Emirates, India and the Philippines, is strengthened. In India, the company is one of the country’s three leading railway engineering companies with contracts in eight of the twelve metros being built. It also works for Japanese clients in the area of chemical engineering.
