Hospital Crane To Be Removed This Week-End With Increased Noise 6am-6pm

Building Care, also called Forest B, of Phase 2 of Children's Hospital expansion is underway and the new building is planned to open in Spring of 2022.

This week-end the tower crane will be removed. The Hospital posted this information:

On Friday, a mobile crane will arrive at the site around noon in preparation for the removal. Expect increased noise and truck activity to and from the construction site.  We do not anticipate any impacts to street parking or traffic flow.

Sellen Construction has submitted a noise variance request to the City of Seattle, which would allow work to occur outside standard construction hours: Saturday and Sunday from 6am-6pm. 

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 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 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).

Lights were added to the horizontal swing arm (boom) portion of the tower crane to increase safety for helicopter landings. These are in addition to the lights at the end of the boom and on the crane operator’s cab. The additional lights will help the helicopter pilots in identifying the location of the boom when landing or departing the helipad in the dark. While the lights are visible from the ground, they are not bright enough to interfere with any neighboring properties. As a reminder, the tower crane is scheduled to remain onsite through August 2020.
