Construction Updates


The Construction Trailers are Setting Sail


The modular building and fleet of trailers stationed on the north side of the Building Hope expansion are pulling up anchor. The collection of temporary construction facilities is regrouping on the south side of the building over the next week or two. The facilities will remain there for the duration of the project.

Work Near Whale Garage Starting Monday, April 30

You may notice a truck and trailer parked at the east end of the fire lane for the Whale Garage starting Monday, April 30. The rig will be there a few days while a contractor runs communication cable along Northeast 45th Street between the garage and the Building Hope expansion. Crews will be present throughout each work day, but the project will not conflict with access to the garage or the bus stops along 45th. In addition, the truck will not be left unattended so it can be moved in case of emergency.

Steel, Glass, Stone and Tile

As contractors rapidly cover steel beams in a cladding of stone, metal and glass, it’s exciting to see how this combination of exterior materials is bringing our Building Hope expansion to life.

The number one goal for the design is to fit in – with existing Seattle Children’s buildings, with the surrounding landscape and with the neighborhood. Yet the design is also meant to be distinctive and incorporate playful touches befitting a children’s hospital. Read full post »

Fence Remodel and Landscaping Work along NE 45th Street Taking Place Monday, April 9

On Monday, April 9, some work will be taking place along NE 45th Street adjacent to the Building Hope construction site. Work includes opening up part of the fence on the east side to remove the brick wall and grade the area, which should be complete by end-of-day Monday. On Tuesday, crews will perform work to tie into the storm drain. They anticipate having the work complete by the end of the week, including sidewalk and fence replacement.

Sellen will have people in place to assist pedestrians around the work area. After hours, the work area will be covered, temporary fencing will be in place and the area will be secured for pedestrians.

Although the work will not impact street traffic, activities will be visible from NE 45th Street.


Building Interior Work

The work on the exterior of Seattle Children’s Building Hope expansion is clearly visible, but an enormous amount of work is taking place inside the new building too!

Crews are working hard to install the metal stud-framed walls that make up most of the interior partitions, as seen in this photo. They are also installing fire sprinklers on all floors, and running duct work for air handling units and conduit for all the power and lighting systems. Read full post »

Ground Covers, Grasses and Trees… Oh My!

Last week we shared how Seattle Children’s is incorporating green roofs into the new Building Hope expansion.  But there’s also a lot of green that will make its way back to the ground around the new expansion in the coming months.

Before the construction site was cleared, over 4,000 plants were saved so they could be replanted around the new expansion. They’ve been lovingly cared for by Children’s Grounds Maintenance team. Read full post »

Turning Gray Roofs Green

Many natural elements are being incorporated into the Building Hope expansion, not only for healing and aesthetic purposes, but also for environmental friendliness and sustainability.

A feature starting to take shape on the new expansion are the “green” roofs… which are literally roofs covered in vegetation. Read full post »

Mock Patient Room

Guest Blog from Todd Johnson, VP Facilities

It has been exciting to see the exterior work on the building begin and interior construction is starting to take shape. I spent some time over the past month working with our construction and internal teams to create a ‘mock’ patient room. Until now we have only been able to use cardboard and tape to develop what we believe will create an optimal patient experience and new model of care. It has been great to see a real room take shape.

Floating Bridges in the Sky?

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.
