What Dlz does

DLZ Corporation is a multidisciplinary architecture, engineering, surveying, environmental, and construction services firm founded in 1916 and headquartered in Columbus, Ohio. The firm operates through a network of 30 U.S. offices and the DLZ Carbon subsidiary in San José, Costa Rica, employing more than 900 professionals including 200+ construction managers and 50+ full-time field survey crews. Its service portfolio spans architecture, transportation (bridges, traffic, right-of-way, design-build), water and wastewater treatment, geotechnical engineering and drilling, environmental consulting (including PFAS and brownfields), materials testing, program management, ADA compliance, landscape architecture, industrial engineering, and clean energy (hydropower, solar, wind, green hydrogen). Underlying technology is centered on REVIT/BIM, GPS/GNSS surveying, 3D laser scanning, UAS/drones, hydrographic echosounder systems, and ESRI ArcGIS, with materials testing laboratories validated by USACE-ERDC and accredited by AASHTO.

DLZ generates revenue primarily through project-based professional service fees, with roughly 80% of work performed for public sector clients (federal, state, municipal) and 20% for private customers, achieving an 85% repeat business rate. Federal relationships span the U.S. Army Corps of Engineers across multiple districts, the FBI, USPS, and Army National Guard, supplemented by direct contracts with state DOTs in Ohio, Michigan, Indiana, Pennsylvania, and Kentucky, transit authorities including the Chicago Transit Authority, and municipal water/wastewater clients such as Great Lakes Water Authority and Detroit Water and Sewerage District. Beyond fee-for-service work, the firm owns and operates seven hydropower plants in India totaling 73.5 MW through subsidiaries and participates in a $2 billion green hydrogen, solar, and wind project in Latin America. Ownership is private, family- and minority-held; leadership is provided by Chairman and CEO Vikram "Raj" Rajadhyaksha, with recently appointed C-suite executives overseeing finance, legal, and human resources.
