Colamette Construction is an Oregon-based general contractor experienced in collaborating with architects and design teams as well as overseeing design/build projects. Over 80 percent of our work is done on a negotiated basis, yet we remain very competitive on bids.

Since opening its doors in 1979, Colamette has served dozens of clients in Oregon and SW Washington on a variety of types of commercial projects
. We've demonstrated time and again our ability to provide clients with exceptional service to meet their construction needs. Repeat clients include such firms as Qwest (formerly US West), Anthro Manufacturing, Allied Systems Company, Rex Hill Vineyards, Bonneville Power Administration, and DEXCO Trust.

Colamette strengths include competent and accurate construction estimating, preliminary design review for cost-effective construction methods and a special brand of team spirit. We take pride in our ability to listen and discern what is most important to our clients and our skills in communicating and developing methods of construction which will meet the immediate needs of our clients.

The Colamette team, led by founder and principal owner Jim Hirte, professional civil engineer, includes project managers and superintendents with educational backgrounds in engineering, construction engineering management and finance as well as decades of on-the-job experience in all aspects of construction. The company averages 40 field employees year around, including nine project superintendents. Office staff consist of four project managers, two assistant project managers and support staff.


"It wasn't until I talked to Jim Hirte that I had any confidence that this job could be done in time and in the way I really needed it done. Colamette hit every deadline."

Tom Kreutner, Autumn Wind Vineyards


Jim Hirte, responsible for overall operations of the company, maintains an active role in all field operations as well as coordinating the activities of the 13 person main office. Jim is a registered Professional Engineer in Civil Engineering and a Certified Document Technologist with the Construction Specifications Institute.

Colamette Construction has the capacity to handle both large and small projects. Management strengths enable Colamette to maximize clients' budget and program needs. Diverse capabilities allow Colamette to handle several phases of field work themselves including all concrete work, framing, and installation of building specialties.




Colamette's budget estimating and scheduling experience as well as an ability to complete projects in a timely and efficient manner make the firm a strong contender for this method of contracting. The firm offers a team-based consultation that embraces problem-solving opportunities. Colamette has completed dozens of projects in this manner including The Oregon State University Industrial Building, Qwest (formerly US West) Alpine Switch, Western Oregon State College's Valsetz and Campbell Halls and the Newberg Public Safety Building.

"Oftentimes a contractor is oblivious to design but this was not the case with Colamette Construction. They were sensitive to the design, finishes, details and specification and when necessary offered helpful and cost-effective solutions to on-site situations. On a personal note, I felt as though we were a team working together with a common goal."

Gordon Thompson III, Design Director, Nike


Colamette assists with constructability reviews as well as budget and scheduling. We work with the design team to provide the best value for the client's needs and routinely provide as many alternatives as possible and with each alternative explain the life cycle costs as well as the initial cost data. By working together, Colamette has found ways to shave significant dollars off projects, including over a million dollars in the complicated renovation of Campbell Hall at Western Oregon State College.
