The global construction market is driven by infrastructure megaprojects, the energy transition, and industrial reshoring (such as semiconductor plants and data centers).

The world's leading construction companies with the largest project portfolios (backlogs) and the highest growth projection for the next 5 years are mainly divided between state-owned giants from China and multinational corporations from Europe and the United States.

For the next five years (2026–2031), global oil refinery construction will undergo a profound geographical shift. The market is set to add nearly 5.8 million barrels per day (mb/d) of new capacity. 90% of these projects will be heavily clustered in three specific regions: Asia-Pacific, Africa, and the Middle East.

Over the last decade, the global oil refining sector has shifted toward massive, highly integrated petrochemical complexes. Driven by strict global regulations for ultra-low sulfur fuels and an increasing demand for chemical feedstocks, several multi-billion-dollar megaprojects were successfully commissioned.
