Drivers and neighbors around the Rose Quarter will see the I-5 Rose Quarter Improvement Project keep one of its two lead builders on the job. Raimore Construction will stay on as construction manager/general contractor partner, reversing its earlier plan to exit in early 2027.
Why it matters
Raimore had said it would finish its role early next year, and the project's continuity depended on how that exit was handled. The earlier decision was rooted in several years of schedule changes and funding uncertainty, and the firm and the Hamilton-Sundt Joint Venture have since found a path for Raimore to continue, addressing its business considerations.
The project's construction partnership dates to a 2020 selection by the Oregon Department of Transportation. The announcement, made in late October 2026, does not disclose contract values or schedule figures, and Raimore has not offered further comment on the terms.
The players
Raimore Construction
A construction firm serving as construction manager/general contractor partner on the I-5 Rose Quarter Improvement Project. It will remain on the project after earlier planning to exit.
Hamilton-Sundt Joint Venture
The joint venture selected by the Oregon Department of Transportation as the project's construction manager/general contractor, which announced Raimore's continued role.
Oregon Department of Transportation
The state agency that selected the joint venture in 2020 and oversees the I-5 Rose Quarter Improvement Project.
The details
The Hamilton-Sundt Joint Venture, in association with Raimore Construction, was selected by ODOT in 2020 as construction manager/general contractor for the I-5 Rose Quarter Improvement Project. During transition planning, Raimore and the joint venture continued discussions and found a way for Raimore to stay on, and the agreement is described as supporting the project's needs going forward. In Phase 1A, Raimore is delivering seismic improvements to the I-5 overpass at the south end of the Rose Quarter and mentoring Phase 1A subcontractors, and it has also taken part in cost and schedule coordination during preconstruction.
Timeline
2020: ODOT selects the Hamilton-Sundt Joint Venture, with Raimore, as construction manager/general contractor.
Early 2027: Raimore's previously planned exit from the project, now replaced by continued participation.
Late October 2026: The Hamilton-Sundt Joint Venture announces Raimore will remain on the project.
Beyond the Bridges
The 2020 ODOT selection of the Hamilton-Sundt Joint Venture, with Raimore as a partner, set up the builder team for the Rose Quarter work. This October 2026 announcement extends that arrangement rather than replacing it, keeping the 2020 team intact as Phase 1A work continues.
If you commute through the Rose Quarter, the I-5 work will keep the same builder team in place as it moves through Phase 1A, including the seismic work on the south-end overpass. Watch for further project updates from ODOT as construction proceeds.
The takeaway
The builder team for the Rose Quarter project remains the same as before, which helps keep the Phase 1A work on its existing path. Keep an eye on ODOT's project updates for any schedule changes that follow from this continuity.
