Four106, an office tower project in Bellevue, Washington, reached a construction milestone with the completion of the mat slab pour

Bellevue Office Tower Reaches Construction Milestone

Mortenson, a leading construction firm headquartered in Kirkland, WA, reached a construction milestone—the mat slab pour—at Four106, an office property in downtown Bellevue, WA being developed by Patrinely in partnership with affiliates of Dune Real Estate Partners.  

This marked a major step forward in the construction progress of the 485,000-square-foot 21-story tower.  

“After a tremendous effort by the Mortenson team in digging out the foundation, we’re excited to have reached this milestone and to be building back up towards the sky,” said Matt Chamberlain, Patrinely’s EVP responsible for the Western U.S. 

In addition to Patrinely, Dune and Mortenson, the project team includes architect Collins Woerman, and structural engineer DCI. The Broderick Group is leasing Four106 on behalf of Patrinely and Dune.
