Among the 100 top-billing construction companies of 2018, seven are Spanish. Among them, they constitute 5% of the total sales worldwide, which consolidates Spain in sixth position behind China, Japan, the USA, France and South Korea, according to the GPoC ranking elaborated by Deloitte

74% of the companies analyzed in the study registered an increase in their revenue during the previous year. The largest construction companies are found in China, due to the size of the market (41 % of total revenue), Europe (26 %) where its companies lead the ranking in international sales, Japan (13 %), the US (9 %) and South Korea (7 %).
Actividades de Construction y Servicios (ACS) is the Spanish company best positioned in the ranking, located in seventh place behind five Chinese and one French firm. Acciona holds in the 37th position, while Fomento de Construcciones y Contratas (FCC) occupies 43rd place and Ferrovial 47th.

Growth opportunities abroad are a strategic objective for construction groups, mainly European and American companies. However, strategies of internationalization introduce additional risks. The report reveals how groups with the highest international activity had lower profits than those that focused mainly on national products.
Many companies are diversifying their services to reach sustainable growth and increase margins, although a higher diversification generally leads to higher debt.
The study concludes with the tendencies seen in the sector, characterized by the a) innovation of new materials, standarization and the application of digital technologies, robotization, drones, wearable and artificial intelligence, b) sustainability; more and more, an indispensable requirement for the sector and c) an improvement of the practices of compliance, modifying hiring practices, regulation of the industry and increasing transparency on a global level.
