​We Succeed Together
We were founded in 1978 behind the common goal of providing the highest level of planning, design, and implementation services to our valued clients. In the decades since, we’ve never lost sight of our fundamental beliefs while partnering with public utilities, municipalities, and government agencies to deliver superior, sustainable, and customized engineering solutions that exceed expectations.
​
Today, we service the Pacific Northwest with over 150 professionals based in nine offices throughout Washington, Oregon, and Idaho. We pull from our collective experience, deep knowledge, and technical proficiency to provide clients with engineering excellence over a wide range of services covering multiple specialties.
​
As we’ve expanded our operations along with our capabilities, we continue to promote growth, innovation, and a culture of care. We achieve this by investing in our people, hiring the best of the best in their chosen fields and equipping them with the technology, resources, and internal support required to meet our uncompromising standards of quality and customer service.

It’s our shared Mission to improve everyday life in our local communities. We fulfill this commitment through technical expertise, creative solutions, and forging trusted relationships with our clients and project partners.
Our Values strengthen our efforts.
