WHAT WE DO

Multidisciplinary Engineering Services in Washington and Oregon

Columbia Engineering Group delivers civil, structural, mechanical, electrical, plumbing, and fire protection engineering services with integrated project support for public and private sector clients.

The Interdisciplinary Advantage​

Columbia Engineering Group brings a holistic approach to every project. By integrating all engineering disciplines under one strategic vision, we eliminate coordination gaps, reduce change orders, and deliver solutions that are technically excellent, constructable, and cost-effective.

Civil Engineering

Our civil engineering team delivers comprehensive site design, grading, utility coordination, stormwater management, and public infrastructure solutions. We serve public agencies, municipalities, and private developers with code-compliant, cost-effective designs that stand the test of time.
