Webuild SpA (formerly Salini Impregilo SpA)[2] (Italian pronunciation: [saˈlini impreˈd͡ʒiːlo]) is an Italian industrial group specialised in the construction and civil engineering business headquartered in Milan. The company was formally founded in 2014 as the result of the merger by incorporation of Salini into Impregilo. Salini Impregilo is the largest Italian engineering and general contractor group and a global player in the construction sector.

The company is active in over 50 countries of 5 continents (Africa, America, Asia, Europe, Oceania) with 35,000 employees. Its experience ranges from the construction of dams, hydroelectric plants and hydraulic structures, water infrastructures and ports, to roads, motorways, railways, metro systems and underground works, to airports, hospitals and public and industrial buildings, to civil engineering for waste-to-energy plants and environmental protection initiatives. It takes first place in the water sector of the Engineering News-Record rankings, the benchmark for the entire construction industry.[3]

The company is listed on the Milan Stock Exchange. It is directed by Pietro Salini.


The company was founded as Impregilo in 1959 and expanded following a merger with Cogefar-Impresit S.p.A., Girola S.p.A. and Lodigiani S.p.A. in 1990.[4]

In 2011 Salini, privately held, began its acquisition of Impregilo with an initial purchase of shares, reaching 25% the following year. The acquisition set a precedent in Italy because it was the first proxy fight for control of a company to occur in the country. Despite the opposition it faced from a group of investors, Salini managed to convince enough shareholders at an assembly in July 2012 to approve its proposal to replace Impregilo’s board of directors with its own list of candidates. Once in place, these new members of the board approved Salini’s offer to buy the rest of Impregilo. Pietro Salini became chief executive. A few months later, the board approved Salini’s plan.[5]

In 2013, Salini launched a tender offer to buy the remaining ordinary shares in Impregilo. In January 2014 the transaction was completed forming Salini Impregilo.[6]

On 18 December 2018, Marco Bucci, the mayor of Genoa and commissioner overseeing the reconstruction of the bridge over the Polcevera River announced the selection of Salini Impregilo and Fincantieri Infrastructure, via a new company called PERGENOVA, for the reconstruction of the bridge according to a design by Renzo Piano.[7][8][9]

In May 2020, the company wasrebranded as Webuild.[10] In November 2020, Webuild acquired a 65% shareholding in Astaldi.[11]
