ASBESTOS NORTHWEST LLC SURVEY REPORT A SB E S T O S NORTHWEST 30620 Pacific Hwy S Suite 103 Federal Way,WA 98003 Tel:253 9414343 Fax:253 9414175 2. Building Description The original portion of the building was constructed in the 1920's and had seen extensive remodel work. The top two floors were configured as a dormitory and had been abandoned for several decades. Lower floors had been remodeled repeatedly although large quantities of original materials remained. The client intends to retain this portion of the structure although it will be reconfigured as a series of residential units. Built onto the side of this structure was a series of expansions carried out in the 1960's and 1980's. These each contained a large gym and a lower level swimming pool, with offices, classrooms and locker rooms throughout the space. The internal layout was reflective of a history of ad hoc alterations and available plans did not accurately represent the layout. This structure will be demolished entirely. Structural System The original structure was of masonry construction and was a total of five stories tall. The overall original structure appeared largely intact although some changes to the internal layout had likely taken place. The expansions of the 1960's and 1980's were of concrete construction. Vermiculite fill was present in some exterior walls. Finishing Materials Interior walls were plaster throughout the majority of the 1920's portion of the building although some areas of finished drywall were present. Ceilings were suspended grid of fibrous tiles in most areas, with plaster ceilings and sometimes additional fibrous tiles glued in place above. Floors were mostly asbestos containing vinyl tiles with carpet over the top. Windows lacked suspect glazing products. The 1960's and 1990's areas were also mostly plaster walls with some areas of drywall. Floors were carpet over concrete in many areas although vinyl tiles were in place below in some rooms. Ceilings were the same as in the 1920's areas. Mechanical system The building had a total of four different mechanical spaces. The 1920's boiler room contained a large quantity of asbestos containing wrap, gaskets and cladding. This material was in some cases damaged and was visible throughout this floor of the building. It was also visible in the walls of the 4th and 5th floor dormitory areas and should be presumed to be in place throughout the building. The large room associated with the 1980's remodel had no asbestos containing insulation products in place. The same held true for the pool mechanical room directly below this. 4
