Celebrating 40 years in business, Triad has earned an impressive reputation for producing high-quality solutions for a variety of project types around the Pacific Northwest.
From our Woodinville office, our experienced civil engineers, surveyors, planners and landscape architects combine best practices with creative thinking to enhance the built environment.
On the private-sector side, we focus on residential development, working for many of the region’s premier architecture and engineering firms, land developers and homebuilders, general contractors and construction companies, real estate companies and private property owners.
For our public-sector clients – counties and cities, utility and school districts, and others – we work on projects ranging from topographic surveys and comprehensive plan reviews to park design and infrastructure improvements.
And there’s more to Triad than just great technical expertise. Every day our employees, clients and community benefit from our empowering corporate culture, solid core values, lasting personal connections, and commitment to sustainable practices.
