The company operates four offices across the Mid-Atlantic region – in Mechanicsburg, Philadelphia, Phoenixville, Pennsylvania, and Largo, Maryland – and an AASHTO-accredited and USACE-validated Materials Testing Laboratory, enabling comprehensive quality control services for infrastructure projects.

Transportation infrastructure represents nearly 90% of AEG's project portfolio, ranging from bridge and highway design to major expressway developments, as well as transit projects. The firm also maintains significant expertise in ports, dams and levees, landfills, renewable energy facilities, and complex civil infrastructure.

Building on Momentum

The AEG acquisition follows a series of strategic moves that have positioned SOCOTEC as a major player in U.S. construction and infrastructure services. Alongside its strategic acquisitions, SOCOTEC has pursued organic growth, recently establishing new offices in high-growth markets including Austin, Texas, to meet surging demand for infrastructure and construction services across key U.S. metropolitan areas. This dual-track expansion strategy reflects SOCOTEC's commitment to delivering comprehensive, locally responsive services while building a robust national platform.

Nicolas Detchepare, CEO of SOCOTEC USA, said: "AEG brings exceptional technical depth, an outstanding reputation for transportation infrastructure excellence, and decades of trusted client relationships throughout Pennsylvania and Maryland. As we establish our presence in these strategically important markets, AEG provides the ideal foundation for growth. Together, we will deliver enhanced capabilities and resources to support the region's critical infrastructure needs while maintaining the local expertise and client service that have defined AEG's success for more than six decades."

Herve Montjotin, CEO of the SOCOTEC Group, added: "As the highly skilled AEG team joins SOCOTEC US in Q1 2026, we're reinforcing our commitment to expanding our U.S. operations – a cornerstone of the SOCOTEC Group's strategic vision – while enhancing our distinctive TIC capabilities in the infrastructure sector."

Vijay Gupta, CEO of American Engineers Group, concluded: "Joining SOCOTEC creates tremendous opportunities for our team and clients. For 65 years, AEG has been committed to delivering engineering excellence and building lasting relationships throughout the Mid-Atlantic region. SOCOTEC's global resources, technical breadth, and commitment to quality align perfectly with our values and vision. This partnership enables us to expand our service offerings, access new markets, and continue supporting the infrastructure projects that strengthen our communities. We're excited to contribute to SOCOTEC's growth while maintaining the personalized approach and technical rigor our clients expect."

With the addition of AEG, SOCOTEC continues to execute a deliberate growth strategy that has transformed the company from a specialized consultancy in 2019 into a 1,700-person, multi-disciplinary organization operating across more than 40 offices nationwide and over 25 accredited Construction Materials Testing facilities coast to coast.
