Coughlin Porter Lundeen

If you've worked with us before, perhaps you'll spot some familiar faces, people you see regularly from conceptual design through building occupancy. And if you're new to working with our firm, our bios introduce us through our expertise, credentials, and even quirks. What they don't show are the great lengths we'll go to ensure your project is a success.

Coughlin Porter Lundeen is a civil and structural engineering firm. Focused in the Pacific Northwest, we partner with clients across markets to bring unique project visions to life. We were founded with the goal of exceeding the standards and services provided by engineering firms, and today, almost 30 years later, that vision continues to guide all that we do.

Coughlin Porter Lundeen was founded in 1994 by Jim Coughlin, Steve Porter, and Terry Lundeen. Since then, Coughlin Porter Lundeen has grown steadily from a team of six to a firm of more than 100. Our team donates hundreds of hours each year, both locally and internationally. Members of our team also serve on executive boards of nonprofit organizations including Construction for Change and A4LE. Our team helps guide the industry, contributing to the development of seismic codes and trends, as well as shaping drainage standards and codes.

Underground valet parking for the Norton Building is accessed off of First Avenue, traveling either north or southbound. We are located two blocks from the Pioneer Square Station serving Link light rail. Sound Transit regional, King County Metro, and additional local and regional bus routes are located on Second, Third, and Fourth Avenues nearby.
