Overview
Webuild is an Italian industrial group focused on construction, civil engineering, and the delivery of complex infrastructure. The company was formally created in 2014 through the merger by incorporation of Salini into Impregilo, although its operating heritage includes Impregilo, founded in 1960, and the Salini construction business. It was known as Salini Impregilo until its rebranding as Webuild in 2020. The group works as a general contractor, engineering and construction company, concession-related project partner, and infrastructure developer. Its portfolio covers dams and hydroelectric facilities, hydraulic and water-supply infrastructure, ports, roads and motorways, railways, metro systems, tunnels, airports, hospitals, public buildings, industrial facilities, waste-to-energy works, and environmental projects. Its activities are organized around four broad areas: Clean Hydro Energy, Clean Water, Sustainable Mobility, and Green Buildings. Webuild has operated across more than 50 countries on five continents. Its stated project experience includes hundreds of dams and hydroelectric plants, extensive railway and underground works, roads and motorways, and major bridges and viaducts. The company presents itself as one of Italy's largest engineering and general-contracting groups and as an international specialist in technically demanding infrastructure. Engineering News-Record rankings have placed it at the top of the water-infrastructure sector, a positioning that reflects its long involvement in dams, hydropower, hydraulic structures, and water systems. The modern group emerged from a consolidation process in the Italian construction industry. Impregilo expanded through the 1994 combination of Cogefar-Impresit, Girola, and Lodigiani. It later developed relationships and acquisitions involving Fisia and Todini. Beginning in 2011, the privately held Salini group built a strategic position in Impregilo, eventually obtaining shareholder support to replace the target's board and pursue control. A tender offer and subsequent integration created Salini Impregilo in 2014. The group then broadened its international reach through the 2016 acquisition of Lane Industries in the United States, a majority investment in Cossi Costruzioni announced in 2019, and the 2020 acquisition of a 65% interest in Astaldi. The Webuild name was introduced in May 2020 as part of a broader effort to present the business as an international infrastructure platform rather than solely as a traditional Italian contractor. In 2022, the company announced a proposed acquisition of a majority interest in Australia's Clough Group, subject to due diligence. Webuild remains listed on Borsa Italiana and is led by chief executive Pietro Salini. Its competitive proposition centers on technical expertise, project scale, international execution capability, and participation in infrastructure programs involving mobility, water, energy transition, and urban development.
History
Webuild's corporate history combines the development of Impregilo with the expansion of the Salini construction group. Impregilo was established in 1960 and later grew through a 1994 merger involving Cogefar-Impresit, Girola, and Lodigiani. This consolidation created a larger Italian contractor with capabilities in major civil works and infrastructure. In 1998, Impregilo established a business relationship with Fisia, and in 2010 it acquired Todini. These steps added to the group's construction and infrastructure activities. A more decisive change began in 2011, when the privately held Salini group started acquiring shares in Impregilo. Salini reached a 25% position the following year, leading to a contested effort to obtain control. The campaign has been described as Italy's first proxy fight for control of a company. Although some investors opposed the move, Salini secured sufficient shareholder support at a July 2012 meeting to replace Impregilo's board with its own candidates. The new board then approved an offer for the remaining shares, and Pietro Salini became chief executive. Salini launched a tender offer for the remaining ordinary shares in 2013. The transaction was completed in January 2014, when Salini was incorporated into Impregilo and the resulting group became Salini Impregilo. The new company combined Salini's private construction heritage with Impregilo's established portfolio and international contracting platform. The group continued expanding geographically and operationally. In 2016 it acquired Lane Industries, a Connecticut-based company, increasing its presence in the United States. In 2019 it announced the acquisition of a majority interest in Cossi Costruzioni. In May 2020, Salini Impregilo changed its name to Webuild. The rebrand emphasized the group's international identity and its role in delivering infrastructure rather than focusing on the legacy names of its predecessor companies. In November 2020, Webuild acquired a 65% shareholding in Astaldi. The transaction further consolidated the Italian infrastructure sector and added Astaldi's project capabilities to Webuild's portfolio. In November 2022, Webuild announced that it intended, subject to due diligence, to acquire the Australian-based Clough Group. Today, Webuild operates in more than 50 countries across Africa, the Americas, Asia, Europe, and Oceania. Its work spans clean hydro energy, clean water, sustainable mobility, and green buildings. The group has experience in dams, hydropower, hydraulic systems, ports, roads, motorways, railways, metros, tunnels, airports, hospitals, public and industrial buildings, waste-to-energy facilities, and environmental protection initiatives. It is listed on Borsa Italiana and is headed by Pietro Salini.
