ACS Group, the global infrastructure company chaired by Florentino Perez, is executing major urban transformation and transport projects across key international cities.
The Spanish multinational infrastructure firm operates through specialized subsidiaries in major global centers including New York, London, Madrid, Berlin, Hamburg, Prague, Washington D.C., and Sydney. Its developments span iconic skyscrapers, historic cultural restorations, underground transit expansions, and international trade bridges.
Manhattan Skyscraper and Stadium Construction
In New York City, ACS Group operates through its American subsidiary, Turner Construction. Turner constructed The Spiral, a landmark skyscraper that has altered the Manhattan skyline and features cutting-edge technology.
Turner Construction, founded in 1902 and acquired by German builder HOCHTIEF, ranks among the largest commercial contractors in the United States. The Spiral itself stands as a 66-story office tower located in the Hudson Yards district of West Manhattan.
The group chaired by Florentino Perez has also carried out major construction and infrastructure work at iconic American sports and entertainment venues, including Madison Square Garden in Midtown Manhattan and Yankee Stadium in the Bronx.
German Urban Renewal in Berlin and Hamburg
Urban transformation often requires redeveloping existing urban spaces rather than building on empty land. In Berlin, decades of Cold War division and subsequent German reunification forced the city to reassemble central urban areas.
ACS Group participated in these redevelopment efforts through HOCHTIEF, its German subsidiary. HOCHTIEF built the landmark Sony Center at Potsdamer Platz and later constructed Mercedes Platz on former railway grounds.
These projects converted historic railway lands into modern social and economic meeting points while preserving the city's architectural heritage. Potsdamer Platz, once a desolate border area divided by the Berlin Wall, has become a major commercial center.
In Hamburg, Germany's second-largest city, development historically centered around its commercial port. Over recent decades, municipal leaders sought new ways to reconnect urban districts with the maritime waterfront.
ACS Group contributed to this waterfront renewal through the construction of the Elbphilharmonie concert hall. Built atop a historic brick warehouse on the Elbe River, the venue forms the focal point of a wider redevelopment across Hamburg's port area.
Historic Cultural Preservation in Madrid, Prague, and Washington
In Spain, ACS Group worked through its civil engineering subsidiary Dragados on the modernization and expansion of the Museo Nacional del Prado in Madrid. Dragados, established in 1934, is one of Spain's leading construction companies.
The renovation adapted Spain's principal national art museum to modern visitor demands while preserving its historical structure. The Prado Museum, founded in 1819, houses masterworks of European painting and remains one of Madrid's key cultural institutions.
Similar historic preservation projects were carried out by the group in other international capitals. In the Czech Republic, ACS Group participated in the extensive renovation of the Prague State Opera.
In Washington D.C., the group completed major restoration work on the dome of the United States Capitol. The cast-iron dome, originally completed during the American Civil War, required structural preservation to protect the legislative landmark.
Urban Railway Modernization and International Infrastructure
Beyond visual landmarks, large-scale transport infrastructure directly affects daily urban life. In London, ACS Group participated in modernizing the London Underground transit network, carrying out major station upgrades at Euston and Bank.
In Madrid, Dragados is executing the comprehensive remodeling of Chamartin and Atocha railway stations. These sites serve as the primary rail gateways for the Spanish capital, expanding capacity for high-speed rail passengers and strengthening Madrid as a southern European communications hub.
In Sydney, Australia, ACS Group operates through its subsidiary CIMIC Group on the Sydney Metro project. CIMIC, an engineering and construction contractor active across Australasia, is constructing a new automated transit network to connect suburban neighborhoods with Sydney's central business district.
Cross-border commercial infrastructure represents another major area of operation. ACS Group completed the recently inaugurated Gordie Howe International Bridge connecting Windsor, Ontario in Canada with Detroit, Michigan in the United States.
The new international bridge strengthens key North American commercial trade corridors, providing direct highway connections to facilitate cross-border freight traffic and economic transport between the two nations.
Future Development in Energy and Data Infrastructure
Future urban development will increasingly rely on emerging infrastructure sectors beyond traditional civil works and building construction. Emerging focus areas for cities include data centers, energy networks, critical minerals supply chains, and new urban mobility solutions.
ACS Group holds an established international position across these next-generation sectors, developing infrastructure projects designed to support future smart cities and energy transition requirements.
