Connecting the existing Harborview building to the new building across 9th Avenue in Downtown Seattle called for 10 stories of skybridges to be erected from the bottom up. Logistics for crane and street closure called for a different approach and Apex helped re-engineer the process to allow for top down construction of the structure. After building a temporary work deck, spanning 9th Avenue for pedestrian safety and 24/7 emergency vehicle access to the hospital, which also doubled as a work floor, entire floors were pre-fabricated and picked with 6 air hoists and 4 guide cables. Apex re-engineered the column splices on the bottom of the floors instead of the top.
