3/31, 4/4 & 4/5/2019 Update:

  • Skyscraper section: First and last photos suggest a build rate of 2 floors per 6 days.
  • First pieces of glass present at the corner of 4th Ave & Union St.
  • Fireproofing at level 10.
  • Concrete floorplates poured up to level 16.
  • Safety netting moved up to levels 22-23.
  • Steel floorplates, core and outrigger columns reach level 25, meaning the Liebherr luffer needs another jump.
  • Hotel section: The ground floor is complete and the concrete pour this week filled in the filler section between hotel and skyscraper.

From 214 m (702 feet).














From 200 m (656 feet).

It may be an emergency exit. Here is the current floor plan for the first level from the marketing site and there is no entry indicated.

Okay, so I figure this space will have nothing to do with being any sort of main
common area entrance. It is probably a tenant specific entry for that space.
My glorious if a bit wonky imagination had this pegged as a showcase public entrance...as it damn well should be. A premium space that is at the whim of any tenant willing to foot the bill. Oh well.

3D printing solves complex design of curtain wall on Rainier Square Tower

The cladding system on each story has a different angle.

Special to the Journal

The under-construction Rainer Square Tower, designed by NBBJ with a sloping facade that will stretch 58 stories, incorporates nodes, or connecting devices, made with the 3D printing process.

A curtain wall that will gently curve, making the building narrow as it gains height, will slope up to the 40th floor. The 3D-printed nodes are part of the exterior cladding system extending top-to-bottom on the 850-foot tall building — Seattle's second tallest.

Tony Parker of Walters & Wolf said in a statement that the nodes needed to be made in a “highly accurate” method on a tight production schedule.

Cullen Hilkene, CEO of 3Diligent; “The reality is, 3D printing is most applicable to highly complex geometries,” he said.

“What 3D printing allows us to do is create some unique geometries otherwise impossible or implausible to achieve”






The curving curtain wall of Rainier Square Tower will be connected by 140 nodes.





Nodes were created using powder bed fusion, where an electron beam fuses thousands of layers of metal to create a part.





3Diligent used 3D printing to create the nodes with unique geometries.
