The $40 million One Convention Place project is one of the three developments to the Washington State Convention and Trade Center major expansion. The 22-story tower is cantilevered over the existing Convention Center approximately 25 feet and is designed to allow for connection of structural members for a canopy over Pike Street. The building contains over 300,000 square feet of office space, 50,000 square feet of convention center expansion space and 120,000 square feet of underground parking. The exterior cladding is a combination of pre-cast concrete at the base with conventional curtain wall from level seven up.
ORA was engaged to perform onsite structural inspections and materials testing services as well as overseas structural steel fabrication inspection and nondestructive examination (NDE). Structural steel was fabricated by Samsung Heavy Industries Co. Ltd. at their Koji Island Shipyard Facility and their Tangjin Plant, both located in South Korea. Because of the core column sizes, the core column units were rolled and fabricated at the SeAH Steel Corporation Facility, located in Pohang City, South Korea.
