We are a fourth-generation, family-owned heavy-civil construction company. Throughout the years, we have earned a reputation for professionalism and integrity that reflects our longstanding commitment to the individuals, businesses and resources of the communities in which we live and work. Our extensive resume reads like a catalog of the nation’s infrastructure, with a wide range of diverse and complex projects. With 12 offices in Washington, Oregon, California, Nevada and Hawaii, GBI’s range of projects include airports, bridges, reservoirs and dams, golf courses, harbors, highways, housing developments, marinas, parks, underground utilities construction services, wastewater treatment facilities, wind and solar farms, fisheries, wildlife habitats and more. The success of our company has been a direct result of our steadfast reputation built on quality, safety, trust and respect – and a sound work ethic surpassing four generations of ownership. Of our numerous awards and accomplishments, we are most proud of the loyalty and longevity of our clients and the quality and dedication of our employees who inspired our mission statement: to be the contractor of choice by our clients, employees and the communities in which we live and work.
