ABM

ABM is one of the world's largest providers of integrated facility, engineering, and infrastructure solutions for commercial and institutional clients. The company employs more than 100,000 specialists and serves roughly six billion square feet of space daily across 19 industries, counting more than half of the Fortune 500 among its clients. Its work spans commercial real estate, data centres, semiconductor fabrication, aviation, healthcare and higher education, giving technical and operational staff exposure to a wide range of environments and systems.

The company's services are organised across several lines. Facility Solutions covers cleaning and maintenance, parking and transportation, and landscape and turf management. Engineering & Infrastructure Solutions handles HVAC and mechanical systems, electrification, and operations and maintenance. ABM Connect, its data intelligence platform, is used to make facilities more resilient and connected, while further offerings address performance improvement, electric mobility and EV charging infrastructure, sustainability programmes, and Mission Critical Services for environments such as data centres and semiconductor fabs.

Founded in 1909 in San Francisco, ABM traces its origins to Morris Rosenberg's window-washing business, started with a $4.50 bucket, sponge and mop. The company describes its mission as driving possibility for a healthier, more sustainable world, with an emphasis on diversity across its workforce, resilience in the built environment, and solutions tailored to individual clients. It positions facilities not as passive cost centres but as strategic assets supporting occupant well-being, and operates across the United States and globally.
