A day later, slab removal has spread across a much wider part of the Onni 606 site

The visible slab-removal area at Onni 606 expanded substantially in the 23 hours between photographs taken Monday and Tuesday morning. The July 13 close view showed three excavators concentrated around one sharply bounded patch of broken slab and exposed subgrade. A wider photograph taken at 9:01 a.m. on July 14 shows a long, nearly continuous field of rubble and uncovered ground across much of the visible foreground, with intact slab remaining beyond it.

The two images were taken from different positions and do not support a precise area measurement. Even with that limitation, the change is clear: several slab sections visible around the July 13 work zone have been broken or stripped, rubble piles extend much farther across the frame, and the operation is spread over a broader front. At least four tracked excavators and a wheel loader are visible in Tuesday's image, compared with three excavators and a water truck in Monday's closer view.

The equipment also suggests a continuing break-sort-clear sequence. One excavator at the east side carries a narrow vertical attachment consistent with the hydraulic breaker seen Monday, while bucket-equipped machines work among the fractured concrete. The loader is positioned on the intact upper pad. Those observations describe what is visible; they do not establish contractor production quantities or the depth of material removed.

This remains early earthwork and surface demolition, not evidence that the full five-level garage excavation has begun. The July 14 image does not show a perimeter shoring system or a deep, block-wide cut. Bellevue's dedicated mass-excavation and shoring permit, 21-134212-BV, and the below-grade structure permit, 24-104362-BB, remain the records that gate that later phase.

Still, the day-over-day comparison captures unusually fast visible progress. What was a localized opening Monday morning has become a broad active demolition field by Tuesday morning. The project is removing the last hard surface over a growing share of the block — a necessary prelude to the deeper excavation, but not yet the dig itself.
