What Professional Service Industries does

Professional Service Industries, Inc. (PSI), now operating as Intertek-PSI within Intertek Group plc's Building & Construction division, is a US-based engineering, consulting, and testing firm founded in 1961 and headquartered in Oak Brook, Illinois. The company delivers construction materials testing and inspection (concrete, asphalt, soils, aggregates, steel, roofing, masonry), geotechnical engineering and drilling, environmental consulting (including Phase I ESAs), industrial hygiene monitoring, building science solutions, and specialty engineering services that span the full project lifecycle — from initial permitting through demolition. Testing is performed across a national network of ISO 17025-accredited laboratories and field offices, underpinned by destructive and non-destructive testing capabilities and advanced geophysical engineering methods.

Operating at high unit-volume scale, PSI executes over 30,000 construction projects, 2 million individual tests, 600,000+ concrete cylinder tests, 5,000+ Phase I ESAs, and issues 580,000+ reports per year. Its go-to-market is enterprise field sales targeting civil and commercial construction firms, developers, and major infrastructure projects, augmented by the National Client Program (single-source portfolio management for multi-region enterprise accounts) and a dedicated Major Projects unit for the country's largest building and infrastructure programs. Revenue mechanics are professional-services based, with quote-based, project-specific pricing tied to scope, test volume, and complexity. The company is led by CEO Murray Savage and is wholly owned by Intertek Group plc, a London-listed TIC group with a global footprint of 1,000 locations across more than 100 countries.
