Dewberry Names David Mahoney CEO, Boosts Design‑Build Competition Affecting Jacobs Solutions

Infrastructure Leadership Change Signals Strategic Emphasis on Alternative Delivery

Dewberry names David J. Mahoney as chief executive officer effective April 1, 2026, in a move that underscores the firm’s push into alternative project delivery and disciplined growth in public‑sector infrastructure. The privately held engineering and professional services firm, with about 2,500 employees and roughly $763 million in revenue, appoints Mahoney to succeed Donald E. Stone Jr., who remains an adviser through June. Executive Chairman Barry K. Dewberry cites Mahoney’s experience leading design‑build work and risk management as central to steering the company into its 70th year.

Mahoney arrives with a track record transforming Dewberry’s alternative delivery practice, overseeing more than 175 design‑build projects with a construction value exceeding $23 billion, and leading the firm’s transportation practice responsible for more than $25 billion in construction. He also served as president of Dewberry’s holding company, directing alternative delivery operations and enterprise risk programs across business lines. Dewberry frames the appointment as a continuation of disciplined, growth‑oriented strategy with emphasis on integrated risk oversight and public‑sector leadership.

The move has direct relevance to large multidisciplinary contractors and engineering firms such as Jacobs Solutions, which compete for the same transportation, water and public‑works design‑build contracts. Dewberry’s intensified focus on design‑build and risk‑sharing models signals tighter competition in state and local infrastructure procurements and may accelerate partnerships or specialization among mid‑tier firms. For Jacobs, the trend reinforces the value of scale, digital delivery platforms and advanced risk management capabilities in winning complex, performance‑based public projects.
