BKF Acquires D R Consultants & Designers, Expanding Infrastructure Services in Southern California

OAKLAND, Calif., Nov. 10, 2026 /PRNewswire/ -- BKF today announced the acquisition of D R Consultants & Designers, Inc. (DRC), a leading Los Angeles-based public works engineering firm. This strategic acquisition establishes a critical geographic anchor in the Los Angeles metro area and significantly expands BKF's capabilities in water and transportation across Southern California.

With a 40-year history in Metro Los Angeles, DRC brings established partnerships with the region's key water and transportation entities. Merging DRC's deep local presence and public sector expertise with BKF's 110-year multidisciplinary civil engineering legacy establishes an end-to-end service offering spanning project inception through construction management.

"DRC's Los Angeles roots and entrenched presence strengthen our regional presence and capabilities. Teaming up is a key step forward in growing BKF's Southern California infrastructure practice," said Darren Riegler, president and CEO of BKF. "Together, we are well positioned to lead complex public infrastructure programs from vision through execution, providing more robust solutions for our clients and opportunities for our people."

This strategic partnership ensures DRC's clients will maintain their dedicated local relationships while gaining access to BKF's expanded full-lifecycle capabilities across planning, civil engineering, land surveying, and construction management. The combined platform pairs deep local agency knowledge with the multidisciplinary strengths required to support and accelerate complex public works and regional infrastructure programs.

"Integrating BKF's regional resources with DRC's institutional trust and municipal experience solidifies our position as the region's premier multidisciplinary engineering firm," said Wanda Martinez, president and CEO of DRC. "Joining forces solidifies our commitment to building a stronger future for our employees and the communities we serve."

The acquisition complements BKF's merger with MNS Engineers, which expanded the firm's construction management, water and transportation design, and surveying capabilities—as well as the additions of Lotus Water, which brought specialized urban water system design and stormwater capabilities, and Waterways Consulting, which bolstered the firm's water resilience and restoration practice.

Now with more than 900 people across more than 20 California offices, the combined firm is Stronger by Design.
