~~.IAC Evaluatian Agreement. l~axycr~est Bu~ld~ng -south Bend TN ZIl 1a~" Page ~, This battery of tests ~.~ been very effective on past projects in determining if a building~related indoor air duality problem exists ar~d v~hen carnbined with the visual. inspection should provide er~~ugh information to decide if there i a "rnald problem" associated with the building. The fund saxnp~es are analysed for both total count and the rank order cif the species present.. These tests identify reer~air of bialagical fungi contamination and bioaerosols associated Frith the interior of the building. irnultaneous autdaor sampling far each suspected indoor cantarninant ~ perform.ed and the existing outdoor air quality is used as the baseline fir evaluating the indaar results. The key to a useful. indoor air quality evaluation is in the preparation of the report, that is, in the interpretation of the results. A report that consists only of the laboratory data and a carnparison chart that requires self-diagnosis, so to speak, ~ not useful.. I have .accumulated and evaluated nun~cricl criteria far each of the tests eve perform. I have a set of current criteria that falXo the recommendations of the nerican Industrial ~Cygiene .Association ~AI~I~~, the American Conference of governmental Industrial Hygienists ~CGIH} and other experts in the field far distinguishing acceptable from.. unacceptable indoor air quality. Their accuracy has been proven innumerous past projects. I believe that our experience in interpreting our test results in the light of these criteria sets our v~or apart. I propose to caXlect one .indaar air sample on sash flag. At each lacation I i11 also collect a carpet. vacuums sample and. make the carbon dioxide and rrloisture rneasuren~ents. In addition I have included ~ samples far surface vvip+es or water-dammed material. one outdoor set of samples will be collected for the baseline used to interpret the indaar results. ~4sb~s~os-'o,~~a~~~~ ateri~cc~s suspect asbestos~containing material sampling will follovr~ the protc~ccol established by the SPA in the ~HHRA regulations ~~a CSR 7~}far schools. They have become the standard of the industry because they present a logical, comprehensive pr~otocal far identification of AC1VIa which gives accurate and reproducible results. Cur pratacal v~ill incorporate the following definitions; • ALA. ~V'e will identify and classify nlr accessible materials, ~ A''E~.~L~: only materials that are acce~sib~~e without penetration behind existing fixed walls, floors and ceilings will b-e sampled; multiple layers an these surfaces will. be sampled. • ASS~I~D: suspect A,CII~ enclosed behind existing walls, floors and ceilings v~i11 be ass~me~ to be the carne material as these on portions of the surface or similar surfaces that are accessible. The survey will include all suspect friable and patentiall~r fr%able materials as defined by the AHE.A~ regulations. e will. not sample any of the asphaltic roofing materials since they are on the exterior of the building and not covered by AI~~RA, but ~vil1 include them as presumed nun-friable AC1VI. e will sample the vari.au suspect flooring materials to provide the mast canaprehensve rnf~orrrration and analyse them by the mare expansive transmission electron microscope ~TEI~I} method, the only method that provides definitive results far these resinous materials. The w~ark will include the docunlentatran necessary to complete the IDE1V1 Notification of I)en~allttan and Renovation operations far any asbestos abatement work that mill be needed far renovating this space iota the high school.
