We are respected throughout the industry for our quality workmanship, integrity and willingness to work with our clients to make each project a success.

Abilities & Services

We specialize and excel in construction projects over bodies of water, or with difficult access, where our experience in constructing work bridges, cofferdams, barging in materials and equipment, and solving difficult access problems are a must for the successful completion of the project. Hamilton offers a complete range of construction management and design services for turn-key projects. A leader in the Design/Build and Construction Management/General Contractor (CM/GC) arenas, Hamilton became Oregon's first Design/Build contractor in 1998; and both Oregon and Alaska DOT's chose Hamilton as their first CM/GC partners in recent years. Remaining innovative helps us meet our client's needs today and will carry our firm forward toward meeting the needs of tomorrow. Whether it be bridges, dams, RR trestles, marine wharfs, pile foundations, steel fabrication, concrete boring & sawing, Hamilton has the managerial and engineering expertise, equipment and skilled personnel to handle the job.


Hamilton Construction has been meeting the individual needs of our clients since 1939. We have grown from a small firm building concrete roads and irrigation systems in Oregon, to a corporation performing over $100 Million annually in concrete and steel construction throughout the Western states. During this time, Hamilton has met the demanding needs of both public agencies and private firms, including Oregon, Washington State, California, Colorado and Alaska DOTs, U.S. Army Corps of Engineers, Union Pacific Railroad, Tri-Met, Weyerhaeuser, Georgia Pacific and Portland General Electric to name a few. We have worked with many of our clients for over 40 years. A proven track record of quick response and reliability make us the first choice of many agencies and firms facing time-critical and emergency situations.
