Specialty geotechnical contractors continue to play a significant role in complex foundation and infrastructure projects, where ground conditions and subsurface engineering requirements influence construction methods. Keller has retained its leading position in the deep foundations category of Engineering News-Record's 2026 rankings, extending a record of top placement that dates back to 2019.
Keller ranked No. 1 in ENR's 2026 Deep Foundations category, continuing its position at the top of the list for the eighth consecutive year.
The company's history in the category also includes its affiliate Hayward Baker, which held the leading position for 17 years before 2019.
The ranking reflects Keller's position within the specialist foundation construction sector, which supports projects requiring engineered ground solutions and subsurface structural systems.
ENR conducts annual industry surveys covering companies involved in general contracting, specialty contracting, engineering, architecture, planning and related professional services.
Its rankings are based on annual revenue generated in domestic and international markets. The assessment provides an industry benchmark for comparing the scale of businesses operating across different construction and engineering disciplines.
Keller's continued placement at the top of the deep foundations category highlights its established presence in specialist geotechnical construction.
Deep foundation systems and ground engineering solutions are essential to infrastructure, industrial, commercial and institutional construction where conventional foundation methods may not be suitable.
Keller's continued No. 1 ranking provides an indication of its scale within the international deep foundations market. For construction owners, developers and engineering firms, specialist contractors in this sector remain important partners in addressing subsurface conditions and foundation requirements on complex projects.
