AECOM

About AECOM

AECOM is the world's trusted infrastructure consulting firm, providing professional services across the full project lifecycle. Its people work as planners, designers, engineers, consultants and program and construction managers, delivering work that spans cities, transportation, buildings, water, new energy and the environment. The company's stated belief is direct: infrastructure creates opportunity for everyone - uplifting communities, improving access and sustaining the planet.

History

AECOM was formed in 1990 through the merger of five entities, although several predecessor firms carried distinguished histories stretching back more than 120 years.

Technical Excellence and Digital Innovation

The firm's TechEx programme connects specialist expertise across its global network, on the premise that ideas have no borders and the full scope of its knowledge should be available to any client regardless of location. Alongside this, a dedicated digital innovation practice applies technology to deliver outcomes that traditional consulting methods could not.

Sustainability

Sustainable Legacies is AECOM's environmental and social strategy, covering emissions reduction, social value delivery and the responsibility to protect, enhance and restore natural and social systems. Given the scale of infrastructure the firm designs each year, its standards on carbon and resilience influence outcomes well beyond its own operations.

Market Position

AECOM sits at the very top of the global infrastructure consulting market, competing with the largest multinational engineering firms. Its combination of scale, market breadth and lifecycle coverage lets it support owners from initial business case through design, procurement and construction into operation.
