What Tran Tech Engirneering does

TranTech Engineering, LLC was a civil engineering consultancy based in Bellevue, Washington, that delivered structural and civil engineering services for transportation infrastructure projects, with a specialization in bridges, structures, and roadways. Founded in 2005 and operating with a workforce of 50+ professionals, the firm served government and public-sector clients — primarily state departments of transportation, municipalities, and adjacent infrastructure owners — through project-based consulting engagements typically secured via RFP and direct relationship processes.

The firm's revenue model was professional services: project-based consulting with contract-specific pricing, no public pricing disclosure, and a go-to-market built on direct project engagements (enterprise field sales) augmented by industry events and conferences as a top-of-funnel channel. Customer segmentation was vertical, with public-sector agencies as the primary segment and infrastructure/construction firms as a secondary one.

On September 28, 2024, TranTech was acquired by David Evans and Associates, Inc. (DEA), a multi-discipline engineering firm. The acquisition added 50+ employees to DEA and integrated TranTech's operations across multiple DEA Washington offices; all TranTech email is now forwarded to DEA. Post-deal, TranTech functions as a wholly-owned operating subsidiary of DEA, with its bridges/structures/roadways practice folded into DEA's broader Transportation services portfolio alongside Energy, Land Development, Water and Environment, Surveying and Geomatics, and Marine Services.
