With zero ground footprint available on an occupied 19-story tower in South Lake Union, fixed-frame industrial scaffolding was not an option. We rigged four motorized swing stages from heavy-duty roof outriggers, completing the full installation in three days. A heavy-duty shrink wrap containment system turned the façade into a weatherproof enclosure, letting the glazing crew work straight through two weeks of Pacific Northwest rain. A sidewalk protection canopy below kept pedestrian access fully open throughout the project. Total access costs came in 28% below the original ground-up frame estimate.
