Current phase

Early excavation and soil characterization — shoring pending

Excavators and a dozer are spread across a broad, graded early-works area, while a compact tracked drill rig is staged for environmental soil characterization. A July 28 city inspection documents soil export; full shored excavation has not started.

Next gate

Limited early grading and hauling continue while full excavation, perimeter shoring and below-grade construction remain dependent on separate city approvals.

Latest record

All updates
  1. Soil export documented as fuel and utility reviews advanceA July 28 job-conference note under the issued early-grading permit directs crews to maintain a mechanical street sweeper while exporting soils—the first Bellevue inspection entry to state explicitly that soil is leaving the block. On July 29, fire reviewers approved reviews of the pending fuel-cube and utility-extension permits with preconstruction, grounding, fire-line and hydrant conditions. These are narrow review approvals, not permit issuances; the shoring and below-grade permits remain pending.
  2. Tower 2 structural review requests another revisionBellevue completed the Revision 2 structural review of Tower 2 building permit 25-105109-BB on July 23 with a revision request. The reviewer said the Revision 2 submittal was the same as Revision 1 and directed the applicant back to structural comments posted June 24. The permit remains Pending; this is a request for another revision, not an issuance or denial.
  3. July progress report: the cleared block enters early earthworkThe month-to-date record traces a clear transition: remaining surface slab was broken and removed across the block, exposed subgrade widened from a bounded foreground patch to most of the visible site, and the active fleet grew to six excavators plus a dozer by July 21. The work is authorized under the early clear-and-grade permit; it is not yet the deep, shored five-level garage excavation, whose separate permits remain pending.

The project

A four-acre block, rebuilt at city scale.

Local reporting has described Onni 606 as Washington State's largest construction project. The public record shows why.

On a roughly four-acre block bounded by the NE 6th Street Grand Connection and NE 8th Street, Onni Group is building three towers — two residential and one office — joined by a shared, three-story podium. The project is widely known as Onni Bellevue or simply the 606 Bellevue towers. Acquired in 2019 for $116M, the former Barnes & Noble site at 606 106th Ave NE is being transformed into one of Downtown Bellevue's largest mixed-use blocks.

The program totals more than 1,289 residences, over 300 hotel suites and roughly 896,000 square feet of office space, wrapped around a 15,000-square-foot public plaza and a segment of Bellevue's Grand Connection. Excavators and a dozer are spread across a broad, graded early-works area, while a compact tracked drill rig is staged for environmental soil characterization. A July 28 city inspection documents soil export; full shored excavation has not started. Limited early grading and hauling continue while full excavation, perimeter shoring and below-grade construction remain dependent on separate city approvals.

The civic bargain

What the height gives back.

The headline figure of roughly 4,000 jobs is the city's SEPA estimate — it bundles the temporary construction workforce with the permanent positions the finished office, hotel and retail are expected to support, so it is a measure of activity the block will generate over its lifetime, not a single payroll. The 1,289 homes concentrate new housing near the 2 Line. In exchange for building to the 600-foot ceiling, Onni dedicates a 15,000-square-foot plaza and a landscaped segment of the Grand Connection — public benefits intended to outlive the cranes.
