Background Information and Scope of Work On April 28th 2020 Asbestos Northwest, LLC conducted a survey of the two story office building located at 2806 NE Sunset Blvd in Renton WA. AHERA-certified building inspector Sean Butler (#173733) conducted the survey to determine the presence of Asbestos Containing Materials (ACM’s) prior to the demolition of the building to make way for redevelopment of the parcel. The building was unoccupied at the time of the inspection and appeared to be in good condition. There was no significant outstanding damage, and tenants had removed all property from the building. The main floor was divided into two office suites, with five more located on the second floor. The main floor may have contained three suites at one stage, prior to remodel work. The building had undergone some remodel work over its existence, but materials in use appeared to be relatively consistent throughout. For the purposes of this inspection the building was considered to be a single homogenous area. All portions of the building were accessible to the inspector. Potential asbestos-containing materials were located and sampled from the interior and exterior of the building. See Appendix B for a detailed floor plan with sample locations. Materials were located and sampled following AHERA protocol in 40 CFR 763.86, then analyzed in-house at Asbestos Northwest per 40 CFR 763.86. See section 3 for detailed sampling information.

Building Description County records indicate the building was originally constructed in 1982 and has a finished area of roughly 8,600ft2 over two floors. The building was unoccupied at the time of the inspection and was in good condition. It contained a total of seven office suites, the five on the top floor being similar in terms of materials and general configuration. The building will be demolished to make way for redevelopment of the parcel. Structural System The structure was of wood framed construction on a concrete foundation with no basement or crawl space below. The overall building structure appeared to be unaltered from its original form. Finishing Materials Interior walls were finished drywall throughout the building, while ceilings had a suspended grid of fibrous tiles. Floors were mostly carpet although vinyl was present in the bathrooms, utility room and back entrance. Materials in use were typical of a modern office space. Windows lacked suspect glazing products. The exterior was clad in a mix of wood siding and stucco. Mechanical system The building had a forced air heating system, with metal ducting above the ceiling tiles. Asbestos containing tape or wrap materials were not encountered during the inspection process. Electrical system The electrical system was live at the time of the inspection, visible wiring was of the rubber insulated type. The electrical panels were primarily located in the second floor utility room and contained breakers. Insulation The building had fiberglass insulation. No vermiculite or other suspect insulation materials were encountered. Roofing The building had a flat roof of rolled asphalt sheets. Outbuildings There were no outbuildings on the property.

Material Sampling Information Asbestos survey work performed by Asbestos Northwest meets inspection regulatory requirements enforced by federal, state, and local agencies, including Asbestos Hazard Emergency Response Act (AHERA), WAC 296-62-077 (WISHA) and 40 CFR Part 61 (NESHAP) and 29 CFR Part 1926.1101 (OSHA) Definitions Homogenous – Materials with the same appearance, texture, color, and which were applied during the same general construction period. Surfacing Material – Material that has been sprayed-on, troweled-on or otherwise applied to surfaces, such as acoustical plaster, texture and joint compound, and fireproofing materials on structural members. Thermal System Insulation – Material applied to pipes, fittings, boilers, breaching, ducts, and other interior structural components to prevent heat loss or gain. Miscellaneous Material – Building materials such as structural components, structural members or fixtures not included in surfacing and thermal insulation. Survey Methodology Before sampling began, inspectors documented the total surveyed area. A sketch of each space was created, and total square footage was roughly measured. The inspectors then determined the extent of each visible homogenous material throughout the survey area. Materials were classified as surfacing, thermal insulation, or miscellaneous material, and friability was assessed according to AHERA specifications. Materials were sampled according to 40 CFR 763.86. Depending on homogeneity, square footage, and material type, the proper number of samples needed to accurately assess the location and extent of asbestos was determined and collected. At the point of collection, samples were placed in an appropriate container and labeled. Location was noted on the building floor plan, and a description of the material was recorded with the label number. Sampling tools were then wiped clean to prevent contamination between samples. Any suspect debris was sealed. The samples were then counted, and their label numbers were recorded on a chain of custody form. The inspector then signed and released the form to the laboratory with the samples. Samples were analyzed in-house at Asbestos Northwest. Below is a list of all materials sampled. Appendix C contains the laboratory report and analytical results for each sample.

Asbestos Containing Material A homogenous material is considered ACM (Asbestos Containing Material) if one or more samples of the material are found to have greater than 1% asbestos. Analysis can result in both positive and negative conclusions in materials containing less than 10% asbestos, or materials that have very fine asbestos fibers, have been hand mixed, or have asbestos fibers tightly bound in the matrix; therefore, EPA recommends a minimum of three samples be analyzed by PLM for these types of materials. All materials that were sampled during the inspection were analyzed under PLM, EPA Method 600/R-93/116. Laboratory results show that five of the samples taken contained asbestos.

Conclusions The roof had a layer of asbestos containing black mastic in place. This material was point counted at client request and was found to contain less than one percent asbestos by this more precise analytical method. Sheet vinyl in the second floor utility closet and the Suite A bathroom had an asbestos containing backing material. All other vinyl products in use were asbestos free. Black glue dots along one wall of Suite B were found to contain asbestos. These appeared to have been for a full length mirror along this wall. Trace black mastic found on the floor of Suite B was found to contain asbestos. This material appeared to be for a flooring system that had since been removed from the building. The total extent of this material is unknown. This material was point counted at client request and was found to contain less than one percent asbestos by this more precise analytical method. All other materials in use were found to be asbestos free. Any identified asbestos containing material must be abated before demolition can continue. A Certified Asbestos Abatement Contractor must carry out abatement. Different materials require different abatement processes depending on the friability, type of asbestos, and amount of asbestos present. It is important that materials are treated by a Certified Asbestos Abatement Contractor.
