Children's Hospital Construction Activity This Week

Children's Hospital has begun construction activity in preparation for the new Building Care, Forest B, Phase 2 of the expansion, planned to open in Spring of 2022.

The 310,000 square-foot addition will add an eight-story building and will includes diagnostic and treatment facilities, primarily out-patient cancer and others) labs, new state-of-the-art operating rooms, 20 inpatient beds, and a lobby. There will be two floors of underground parking and sterile processing. This will bring SCH bed total to 409, up from 200 before its expansion 2012 plan.

The helicopter landing pad has already moved temporarily to the roof of Forest A (176’), now known as Friends of Costco Building, Phase 1 of the expansion. The landing pad will be active for the next four years, until Building Care is completed Noise is expected to be louder than the former ground-based helipad. When Forest B is complete, the helistop will moves to its permanent location on top of the Friends of Costco Building (same height).
