You may have noticed the sky bridge currently under construction that is connecting the existing building to the Building Hope expansion across five floors. Designing it was a challenge for a variety of reasons: the slope Seattle Children’s is built on; creating fire lane access below the sky bridge; working around multiple underground utilities; and accommodating very different earthquake movements of the two connected buildings.

After considering many options, it was determined that the best solution was to design the sky bridge as a floating structure, with joints at each floor level between the adjacent buildings. The design also incorporates a sloped steel truss that allows the eastern half of the sky bridge at each floor level to hang from a pair of diagonal columns.
