Client: Wright Runstad 1201 Third Avenue Tower
Project: Auxiliary Cooling Loop Expansion, Cooling Tower Demo and Hand Build Replacement
Role: General Contractor
1201 3rd Avenue Building, Seattle, WA is a 57-story office tower constructed in 1987. The building was constructed with a primary chilled water system and an auxiliary condenser water system. The auxiliary system is a dedicated system serving 1201 and Brooklyn Building retail, tenant comfort and data cooling.
Due to contemporary tenant usages, demand on the auxiliary cooling water loop has exceeded the system’s heat rejection capacity. This project consisted of increasing the capacity of the auxiliary loop system by 30% due to increase in building cooling loads.
Construction was performed during mild weather season and employed redundant backup heat exchange system constructed in 2009 by our team to reject the auxiliary loop heat to the chilled water condenser water loop on Floor 35.
The capacity improvement was implemented by:
We take an engineering approach to evaluating and rebuilding equipment and mechanical systems. Our focus is on developing custom engineered solutions to maximize efficiency and value.
