(“Ayesa Engineering” or “Ayesa”), the engineering division of Ayesa Inversiones S.L.U. (“Ayesa Group”). Ayesa Engineering is a global multidiscipline engineering and project management firm headquartered in Seville, Spain, that provides technical consulting services across four continents. Ayesa’s leadership team has retained significant equity under Colliers’ unique partnership model and will drive the operations and growth of the business going forward.
With the addition of Ayesa Engineering’s more than 3,300 professionals, Colliers’ Engineering segment (“Colliers Engineering”) now operates in 23 countries with over 11,000 professionals, firmly establishing Colliers Engineering as a leading global consultancy delivering engineering, design, project management, and other technical consulting services across Property & Buildings, Infrastructure & Transportation, Water, and Environmental end markets.
“Ayesa is a highly strategic acquisition that meaningfully expands the global scale of our engineering business, strengthens the resilience of our earnings, and underscores the power of our partnership model,” said Jay Hennick, Global Chairman and Chief Executive Officer of Colliers. “Our ability to partner with exceptional operators and align them for long-term growth differentiates Colliers.

“This acquisition strengthens our ability to serve clients in attractive, high-growth markets across Europe, Latin America, the Middle East and South Asia, while broadening our technical capabilities on a global scale,” said Elias Mulamoottil, Chief Investment Officer and CEO of Engineering at Colliers. “That expertise is reflected in Ayesa’s complex, high-profile projects such as the design and project oversight of the transformation of the Santiago Bernabéu Stadium in Madrid, the design of hundreds of desalination and water distribution facilities across Saudi Arabia, and the design and project oversight of several metro lines globally including the Bogotá Metro in Colombia.”
“Partnering with Colliers creates an exceptional opportunity for our professionals to become significant stakeholders in the business, reinforcing long-term stability and our focus on delivering the best outcomes for clients,” said Rosalío Alonso, Chief Executive Officer of Ayesa Engineering. “It also gives us the ability to leverage Colliers’ significant engineering operations in the U.S., Canada, and Australia, while benefiting from its more than 30-year track record of scaling global businesses and creating long-term value for all stakeholders.”
