2025 was a landmark year for construction, highlighted by the operational launch of the Grand Ethiopian Renaissance Dam (GERD) and the intense push for 2027 AFCON stadiums in East Africa. Globally, the year saw the opening of the world's tallest bridge in China and a massive surge in AI-driven data center construction, signalling a new technological era.

2025 proved to be a seminal year for the global construction industry, defined by projects of staggering scale, revolutionary technology, and profound cultural significance.

The year also ends on a somber note with the passing of legendary architect Frank Gehry, who died on December 5th at the age of 96. Gehry’s deconstructivist style, which transformed buildings into fluid, shimmering metal sculptures like the Guggenheim Museum Bilbao, leaves behind an impossible legacy, reminding the world that construction is indeed high art.

Across Africa, two major infrastructure narratives dominated the landscape. Ethiopia officially launched the Grand Ethiopian Renaissance Dam (GERD), cementing its status as the continent's largest hydroelectric facility.
