The United States Federal Courthouse is a $150 million complex at Seventh Avenue and Stewart Street in Seattle. This 615,000-sf, 24-story high-rise has 18 courtrooms, 22 judges’ chambers, office administration, a U.S. Marshal Service office and a law library. This project addresses perimeter security design challenges with the use of a one-acre landscaped public area running the length of Seventh Avenue. This area provides open space as well as a barrier that prevents vehicles from getting near the building. 2-foot high concrete bollards will encompass the site, inhibiting vehicle access. The courthouse incorporates an innovative fortified floor design using embedded cables for emergency support, in case a supporting column is destroyed. To handle an earthquake, the building has a large diameter, concrete-filled steel pipe columns and steel plate shear walls. Valley’s electrical responsibility included complete electrical service and distribution systems throughout the entire building, electrical wiring of natural ventilation system via the building management system, which entailed controlling and monitoring operable windows to allow outside air to cool building, building fire alarm and security systems and voice and data cabling.
