or reduced to powder by moderate pressure, such as spray-applied fireproofing and acoustical materials, acoustical ceiling tiles and most thermal system insulation. Non- friable materials are those that cannot be crumbled easily, such as resilient floor tiles and cement asbestos (Transite) board. Although the emphasis is on detecting friable materials, the possible presence of non-friable ACBM must also be considered, since non-friable materials may be pulverized or otherwise damaged and release asbestos fibers into the air during building demolition. The next phase of the surveys will involve the selection of sampling areas and sample locations. Sample areas are typically grouped based on material homogeneity. A homogeneous area is one that contains suspect materials that appear by texture, color and wear to be uniform and applied or installed at the same general time period. After sampling areas have been determined and recorded, representative samples of suspect materials will be collected. Only suspect material samples will be submitted for laboratory analyses. Samples will be sealed in airtight containers, labeled, and forwarded to an approved laboratory for analysis by the EPA-recommended method of Polarized Light Microscopy coupled with dispersion staining. Once sample analyses have been received, results will be reported as a Letter Report to the City of South Bend. The requisite Indiana Department of Environmental Management (IDEM), Notification of Demolition and Renovation Operations forms (with documentation) will also be prepared for signature by an "authorized representative" of the City of South Bend, and subsequent facsimile submittal to the Office of Air Quality. During demolition, Phifer Environmental Services will provide environmental inspection services that include the verification of asbestos removal. Task 2 -Design Services /Demolition Bid Documents CBBEL staff will design and prepare final bid documents for the project. All plans and specifications will be prepared in accordance with City Standards and Specifications. The bid documents will include recommendations provided in the Phase I Environmental Report and Asbestos Survey to address the requirements of the regulatory agencies involved with this demolition. Specifications will be developed utilizing standard specifications and general conditions provided by the City in addition to CBBEL standard specifications. Applicable conflicts will be brought to your attention for your input. CBBEL staff will provide an opinion of probable cost based on the final bid documents. This opinion will be based on the judgment of CBBEL engineering staff, supplemented by local construction project history information provided by the City. Task 3 -Bid Services CBBEL will provide three (3) full copies of the final bid documents to the City prior to bidding. CBBEL will assist the City in conducting apre-bid conference at a location of Christopher B. Burke Engineering Ltd. City of South Bend: Demolition of 1503 / 1505 Prairie Avenue P01.100544.00000 Page 2
