The company turns 55 with a standout portfolio of more than 500 million euros. And it celebrates its anniversary by entering the TOP50 of the 225 largest engineering companies in the world, according to the prestigious ENR ranking. A&M Capital Europe takes a majority stake to position the firm as a global provider of technology and engineering services through acquisitions.


Despite the pandemic, it closed the financial year with a record turnover of 256 million euros and almost 4,800 employees. Major contracts such as the supervision of the Bogotá Metropolitan Railway overhaul are awarded, worth 56 million dollars, the largest signed to date.
