Engineering & Construction

ACS Group combines development, operation, and investment in essential next-generation assets with the execution of traditional infrastructure projects, in both civil engineering and building construction.

We build infrastructure that forms the backbone of territories: transport routes, high-capacity connections, and the facilities necessary to guarantee basic services, such as water supply.

The Group operates this business area through three main companies —Dragados, FlatironDragados, and Hochtief Europe-.We bring together experience and technology to execute complex projects, meeting the most demanding standards of safety, quality, and innovation.
