Quantum Consulting Engineers provided the structural design for a six-story, 68,000 square foot mixed-use project. The client, Low Income Housing Institute, working with the Runberg Architecture Group, provided sustainable features to the building including a large, tenant-accessible green roof with a solar array. The 69 units are a mix of studio, one, two, and three bedroom apartments for families making 30% to 60% of the median income. The ground level includes a four-classroom preschool. The structural system is composed of a slab-on-grade, a post-tensioned concrete transfer slab, and 5 levels of wood framing. The foundation is partially supported on steel piles to mitigate the liquefaction hazard.

The Edgewood City Hall Building is a two-story structure comprising roughly 15,000 square feet. It will encompass administration, building and planning departments, council chambers, community meeting hall, police station and leasable commercial office space. The lower floor encompasses roughly 4,600 square feet, and daylights to the south and west. The main floor is situated partly on grade and partly above the lower floor space. The main floor and roof are wood framed with steel columns. The lateral force-resisting system is comprised of the wood diaphragms transferring forces to plywood-sheathed wood stud walls on both the perimeter and interior spaces. At the high/low roof interface, a system of balloon-framed 6×6 posts will resist lateral forces by cantilevering between the continuous clerestory windows separating the low roof from the high roof and transferring those forces to wood shear walls below.

It shares a common courtyard with the adjacent Ernestine Anderson Place. It was built to meet the Washington State Evergreen Sustainable Development Standard. Energy efficient features include water-conserving fixtures and an enhanced building envelope design. It was named in honor of Abbey Lincoln, an American jazz vocalist, songwriter, actress and civil rights activist.

Seattle University

Seattle, WA

Seattle University’s new bookstore is prominently located at the northeast corner of campus at 12th and Madison. The store occupies ground floor of a five-story, 82,000 square foot, reinforced concrete storage building that was originally built for the Bekins Storage company in 1910. The structural retrofit of the storage building involved removing a concrete mezzanine to create a high retail space, framing a new opening in the ground floor to provide a new entry and then seismically retrofitting the building to current code standards. The seismic retrofit of the building was done using shotcrete shear walls at select opaque perimeter walls, removing or bracing unreinforced masonry partition walls and installing buckling restrained braces (BRB’s) at open window bays. The BRB’s were used in part to keep the brace and end connection sizes to a minimum to reduce their impact to the windows. The construction took less than a year to complete, all while the building was still occupied by the storage tenant.
