FCC is the fourth largest Spanish construction company worldwide, according to Deloitte's Global Powers of Construction. In line with the growth recorded by Spanish companies, FCC climbs positions in the global ranking. ACS has entered the top 10, moving up from 11th to 10th place. Acciona has improved its position by one place, reaching 20th place. Ferrovial has moved up two places to 41st, followed by FCC in 42nd place.

The world's 100 largest construction companies had revenues of $1.978 trillion in 2024, down 1% from the previous year. In contrast to the global decline in the sector, the seven Spanish companies in the top 100 ranking recorded revenue growth of 11.9%, reaching $96.106 billion, compared to $85.86 billion in 2023.

In terms of companies with a higher proportion of their sales abroad, ACS remains second in total figures with $41.145 billion, behind only France's Vinci. In terms of percentage of sales abroad, ACS ranks second with 91.3%, behind only Italy's Saipem with 93.2%. Acciona also enters this ranking in 7th place in total sales with $16.002 billion, meaning that 77.1% of its sales are generated abroad.

Growing urban concentration, with United Nations projections estimating that 70% of the world's population will live in cities by 2050, is driving greater demand for sustainable infrastructure globally.

In this context, together with the major trends of digitalisation and decarbonisation in the sector, large construction companies are looking for ways to strengthen their operating margins. The transformation towards a ‘Smart Construction’ model is positioned as an operational and financial strategy that improves profitability and reduces the inherent risks of the sector.

The main international groups in the sector have already begun this transition. Spanish construction companies have deployed innovation hubs, digital platforms and artificial intelligence solutions aimed at redesigning processes, from tendering to operation. Despite the challenges associated with system integration, data quality and scalability, recent advances are consolidating the role of Smart Construction as a key lever in the future competitiveness of the industry.
