400 University 1 - Conco

In November 2020, The Conco Companies completed its concrete services for 400 University @ Rainier Square, a 10-story office building in downtown Seattle. We were selected based on our experience with similar tower structures in the Seattle market. This building, which was developed by Wright Runstad & Company, required full concrete services ranging from concrete pumping to concrete reinforcement.

This project’s challenges included its proximity to two active construction sites, each with different general contractors. Additional challenges included coordinating our shoring/re-shoring systems, deliveries, safe personnel egress, and COVID checkpoints with the operations of adjacent projects. Conco cooperated with the general contractors to ensure their projects were completed safely and efficiently.

400 University @ Rainier Square provides more than office space; it offers retail shopping opportunities at street level. Overall, it has a footprint of 17,400 SF that slims to 9,250 SF at the tower levels, and 106,000 SF of elevated deck. It’s also part of the larger Rainier Project, which creates a trio of structures that include Seattle’s 2nd tallest building.

Conco is proud to have contributed to a high-profile milestone in the life of Seattle’s skyline, and will continue to help develop the Seattle area.
