In 1957, when Davide Trevisani decided to set up the "Impresa Palificazioni TREVISANI Geom. DAVIDE" in Cesena, he had already in mind the outlines of his plan: becoming the point of reference in the world of foundation engineering.
In order to achieve this goal, he believed in people and focused on a certain type of people, those that are full of wit and passion, always ready for challenges and willing to get involved in the continuous pursuit of excellence in the field of foundation engineering.

Within a few years, the company, which soon changed its name into Trevi, began to reveal a clearly defined structure, with a strong attitude towards technological innovation, the enhancement of human capabilities, know-how updating and internationalization.

In 1962, Gian Luigi, the younger brother of Davide, joined the Company and, with start from the early '70s on, he led to the development of the company in the international markets. Starting from Nigeria (where in 1967 the company acquired the foundation works for the Apapa Road, the first great contract abroad in the history of the Group) and, especially, with Argentina when, in 1971, the company faced and overcame the challenge of carrying out the foundations of the bridges on the Parana river. An intervention that marks a milestone in the history of the company, but also in the history of the industry, because, for the first time, piles were carried out in the water, at a depth of 74 meters.

A few years later, precisely in 1969, Davide and Gian Luigi set up Soilmec; a company specialized in the design and manufacture of plant and equipment used for soil engineering: an insight which marked the birth of a world leader in the field of foundation equipment.

To better support the entry into the North American market, Trevi decided to acquire I.C.O.S. Boston, an historic company that was leader in the execution of special foundations works and that had already become known for having carried out the foundation works of the twin towers in New York.

In 1979, Cesare Trevisani, the youngest of the Trevisani brothers, started his career in the Trevi Group.

The end of the eighties marked the beginning of a steady growth in sales, employees, projects and also of the areas of intervention. These are the years that led and established the Trevi brand worldwide: from Japan (Hasaki Tunnel & Bridge) to China (Ertan Dam), Egypt (the new Library of Alexandria), Argentina (the Brazo Largo bridge over the Paraná river), from Nigeria (Third Mainland Bridge) to the United States (Walter F. George Dam, the Big Dig in Boston, the World Trade Center in New York City), from New Zealand to Italy (where, in 1995, the consolidation works for an Italian art icon in the world begun, that is, the Tower of Pisa), from the Philippines to Angola, from the Middle East (the consolidation of the Bamiyan Buddhas in Afghanistan) to Canada.

In the mid-90s, the Trevi Group embarked on the drilling market for the first time. In partnership with Agip, it began the research and development for the construction of a new rig to drill deep water wells and to search for hydrocarbons.

The business and technology development (including TREVIPARK®, the patent for the automated underground parking) and its increased presence abroad paved the way to listing the holding company of the Group, TREVI-Finanziaria Industriale SpA, at the Milan Stock Exchange, in July 1999.

In the same year Petreven SA was founded; a company specialized in services and drilling works for the oil industry, which began to operate successfully in Venezuela before extending its activities in other countries of the South American continent, including Argentina, Colombia, Peru, Chile and Saudi Arabia.

The Group's objective was to overcome the resistance of the operators in the oil and gas industry, historically tied to North American suppliers, in order to promote the innovative technology "Made in Italy" in the highly mechanical-based culture rather than the hydraulic-based one.
So, in 2004, and through a Soilmec spin-off - Drillmec was born; it’s a company specialized in the design and manufacture of mechanical and hydraulic rigs to perform oil, geothermal and water drilling works. With this move, the Trevi Group not only strengthened the metal mechanical division with a new plant in Piacenza, but entered, with determination, in the market of hydrocarbon drilling works, that had always been the exclusive field of the great American majors.

In 2005, Trevi acquired the business unit Ing. Giovanni Rodio SpA that was founded in 1921; Rodio is the first historical Italian company specialized in the field of geotechnical engineering.

At the beginning of the third millennium, the Trevi Group continued its growth that - in September 2007 - led it to celebrate its 50th year anniversary. The first celebration took place in New York where Trevi had just completed the foundation work at Ground Zero, for the new buildings and transportation hub.

In the same period, Trevi, through its US subsidiary TREVIICOS, was entrusted by the US Army Corps of Engineers to restore one of the most important dams in the country: the Walter F. George Dam. The complex project was completed to the satisfaction of the customer so that, in the following years, the Corps of Engineers relied on Trevi to carry out several remedial measures on large dams such as Tuttle Creek, Herbert Hoover Dike, Bolivar Dam and, especially, the Wolf Creek Dam, which received numerous awards with regard to safety, technological solutions and the delivery time. During the execution of the works for the Wolf Creek Dam, the Corps of Engineers also relied on TREVIICOS for the consolidation of the bank LPV-111 in New Orleans that had been devastated by the Hurricane Katrina. A complex intervention that was completed long before the due delivery time and for which reason it got several awards.

At the beginning of 2010, the Trevi Group received the Leonardo Prize for having brought honor and prestige at national and international level to the "Made in Italy" innovation in the field of great foundation engineering works.

In the same years, the new drilling technology called HH (Hydraulic Hoist) began to establish itself in the field of drilling; it was developed by Drillmec also thanks to the field-testing of Petreven. The business model was based on the continuous exchange between technological and process innovation that has always characterized the relations between the divisions of the Trevi Group and that still manages to strengthen its leadership in the areas of reference and to create new opportunities.

In 2012, the company was commissioned to carry out surveys and preparatory works for the Costa Concordia wreck removal which got stuck in the depths of the island of Giglio. The operation, never attempted before, captured the interest of the entire world's media and succeeded perfectly in July 2014.

Today the Group is an extremely dynamic reality, a Group that is consolidated in the technologies used so far and always researching new solutions adapted to solve problems that nowadays are more and more complex and challenging for civil engineering worldwide. A Group where the most advanced tools in the field of research and technology live along with entrepreneurial tradition and with the will to invest capitals and human resources in order to remain competitive and winning.
