The Immunex Corporation is to build a biopharmaceutical complex in Seattle, Wahington, worth USD 750 million. The massive project, known as the “Helix” project, derived from the name of the double helix structure of DNA, is now well under construction after a ceremonial groundbreaking in January 2001. The Helix project is the first phase of what will eventually be multiple buildings with over 2.3 million square feet to house biopharmaceutical research and development laboratories plus administration offices for 2500 employees. Immunex assembled a design and construction team including the following firms: Affiliated Engineers Inc. (Mechanical, Electrical, Piping and IT), Flad & Associates (Executive and Lab Architect), Koetter, Kim & Associates, Inc. (Design Architect), KPFF Consulting Engineers (Civil and Structural), NDBBJ (Interior Architect) and Sordoni Skanska Construction Company as Construction Managers.
