Fifteen Twenty-One 2nd Avenue, Seattle, Washington
Innovative RCS and ACS Systems Significantly Increase Safety and Productivity
Overlooking the waterfront and Pike Place Market, Fifteen Twenty-One 2nd Avenue is the tallest residential high-rise building in downtown Seattle. With a height of 400’ it will consist of 38 floors, including one retail and nine parking levels, with 143 luxury condominiums.
The full perimeter of the uppermost floors is completely enclosed with RCS P protection panels, providing shelter from the weather as well as unsurpassed fall protection. The VARIO core wall formwork is self-climbed using a combination of ACS and RCS to free up crane time and to facilitate the installation of the reinforcing steel to achieve the seven day typical floor schedule.

“With safety in mind, we decided to use these systems for the first time. The panels keep our workers safe and keep any building material from flying off the building. With the extreme winds we get in Seattle coming right off the lake, this system is amazing and we are very pleased with the higher productivity and cost savings.”
