Do you trust local government to keep major road projects on schedule and budget?

Raimore Construction will remain on the I-5 Rose Quarter Improvement Project, reversing its earlier plan to complete its role early next year. The announcement was made in late October 2026 by the Hamilton-Sundt Joint Venture, Raimore's partner as construction manager/general contractor.

Why it matters

Raimore's earlier decision to leave was driven by several years of schedule changes and funding uncertainty that affected its business. The continued partnership keeps the Portland-area highway project's delivery team intact as work moves forward.

The project's construction manager/general contractor partnership dates to 2020, when ODOT selected the Hamilton-Sundt Joint Venture with Raimore. The updated arrangement does not disclose a revised completion date or cost figures.

The players

Raimore Construction

Raimore Construction is the construction firm partnered with the Hamilton-Sundt Joint Venture on the I-5 Rose Quarter Improvement Project, and it declined an interview and further comment.

Hamilton-Sundt Joint Venture

The Hamilton-Sundt Joint Venture is the construction manager/general contractor that announced Raimore's continued role on the project.

Oregon Department of Transportation (ODOT)

The Oregon Department of Transportation is the state agency that selected the joint venture and Raimore for the project in 2020.

The details

During transition planning, Raimore and the Hamilton-Sundt Joint Venture continued discussions and found a path for Raimore to continue its role. In Phase 1A, Raimore is delivering seismic improvements to the I-5 overpass at the south end of the Rose Quarter and mentoring subcontractors. Raimore has also supported community engagement and opportunities for COBID-certified firms and historically underrepresented businesses.

2020: ODOT selected the Hamilton-Sundt Joint Venture, with Raimore, as construction manager/general contractor.
Early 2027: Raimore's previously planned exit from the project.
Late October 2026: Announcement that Raimore will remain on the project.

Roadmap

ODOT's 2020 selection of the Hamilton-Sundt Joint Venture, with Raimore as its partner, set the delivery team for the Rose Quarter project. The late October 2026 announcement preserves that team structure rather than changing it midstream.

For Portland-area commuters, the Rose Quarter project's delivery team staying in place means the I-5 work is not changing hands midstream. Drivers should continue to expect construction activity on the corridor as Phase 1A seismic work proceeds.

The takeaway

Stability in the contractor team can reduce the risk of further schedule disruption on a large urban highway project. Readers following the Rose Quarter work should watch for updated completion timelines from the project partners.
