Dewberry names Mahoney CEO to expand design‑build, compete with Jacobs Solutions

Dewberry elevates Mahoney to scale design‑build, transportation work

Dewberry announces David J. Mahoney will become chief executive officer effective April 1 and joins the board as the privately held engineering and professional services firm looks to accelerate growth in alternative delivery and transportation markets. The $763 million, 2,500‑person firm, based in Fairfax, Virginia, names Mahoney to succeed Donald E. Stone Jr., who remains in an advisory role through June 30 before retiring. Executive leadership frames the change as a transition to sharpen risk oversight and expand the firm’s public‑sector infrastructure footprint in its 70th year.

Dewberry highlights Mahoney’s track record leading its alternative project delivery practice, where he oversees more than 175 design‑build projects with a combined construction value exceeding $23 billion, and his stewardship of the transportation practice responsible for more than $25 billion in construction and roughly $1.5 billion in revenue. Company statements say Mahoney’s experience shaping risk profiles, partner relationships and project approaches positions Dewberry to pursue larger, more integrated programs. His promotion signals intensified competition among large engineering firms, including Jacobs Solutions, for design‑build and complex transportation contracts that prioritize risk transfer and faster delivery.

The appointment underscores broader sector trends toward integrated delivery, closer contractor‑designer partnerships and heightened emphasis on risk management and alternative procurement. Dewberry intends to leverage Mahoney’s ties to major construction partners and his operational role in cross‑discipline teams to capture public‑sector work and expand client relationships from its Fairfax headquarters. For peers such as Jacobs Solutions, the move reinforces the need to strengthen design‑build capabilities, bolster programmatic risk controls and compete on turnkey solutions as infrastructure spending and accelerated delivery models drive market demand.
