As a result, water leaked into these areas and caused the cable ends to rust, and then corrode. The post-tensioned cables are corroding because the ends of the cables were not properly protected with corrosion preventative paint, and the grout used to seal the cable ends and anchors was not the specified non-shrink grout and was defectively installed. The PRNewswire web site described the McGuire Building's engineering deficiencies: "The building owner has informed officials at the Seattle Department of Planning and Development (DPD) of the extensive construction defects, which principally involve corrosion of post-tensioned cables and concrete material and reinforcement placement deficiencies. They commissioned the Seattle based architecture firm Hewitt Architects, with extensive experience building apartment buildings, and the large-scale builder McCarthy Building Companies to erect this rental apartment tower. Seattle's Carpenters Union, Local 131, and the Multi-Employer Property Trust (MEPT), owned Carpenter's Tower, LLC. Financial incentives were offered to those displaced to ameliorate their transitions out of the building. The decision was made in 04/2010 to evict four commercial lessees and apartment renters in the tower to enable demolition. ) Estimates to repair the reinforcing members ran to $80 million in 2010, apparently twice the cost of building another 25-story residential tower. Its report described ".extensive water damage, rust and some concrete spalling or flaking." Steel, post-tensioning cables were improperly insulated from moisture, and Olympic Associates' report "showed that one-third of the building’s connecting tendons would have failed by 2019." (See Nicole Tsong and Mike Carter, Seattle Times, " 9-year-old Belltown high-rise too flawed to fix," accessed. ) Because a concrete chunk of the highrise fell in 04/2006, the owners commissioned an engineering consultant, Olympic Associates Company, to investigate the building's structural condition. The building's owner, Carpenter’s Tower LLC, sued Hewitt and McCarthy, ".alleging negligence and failure to adhere to industry standards." (See Nicole Tsong and Mike Carter, Seattle Times, " 9-year-old Belltown high-rise too flawed to fix," accessed. Built at a cost of $32 million, the 272-unit building was designed by Seattle's Hewitt Architects and erected by the Bellevue office of McCarthy Building Companies.
One of a group of apartment towers built in Seattle's Belltown neighborhood during the late 1990s and early 2000s, the McGuire Building, finished in 2001, attained notoriety for structural flaws that required its demolition about 10 years after its completion. The McGuire Building was located at 2nd Avenue and Wall Street.
