This project is a complete remodel of a historic 9-story high-rise building located downtown on 4th & Marion. Originally constructed in 1929, the top 4 floors have an open “atrium” which is being in-filled adding 20,000 square feet for a total of 104,000 square feet. There is an existing pool on the ground floor being demolished for a new larger state of the art swimming pool. Complete design and construction for all new fire, plumbing and HVAC systems. There were extremely tight design constraints due to untouchable historical building components. Several ceilings and finishes are remaining as part of a historical building preservation plan with the City of Seattle. Facility includes: office space, conference rooms, basketball and racquetball courts, running track and cardiovascular equipment room, swimming pool and spas, and a motel. Significant asbestos abatement was completed two months into the project. Multiple mechanical systems designed and installed by McKinstry to support the mixed use of this unique facility include: floor by floor and rooftop VAV/AC units, constant volume heating and ventilation systems, hydronic hot water heating systems, heat recovery systems, steam to hot water heat exchangers for domestic, pool and heating water, stairwell and elevator pressurization, and installation of 227 new plumbing fixtures. Significant value engineering included the deletion of fire system booster pumps typical for high-rise requirements. |
