well as, to assist in the identification of ACM or suspect ACM. Other documents such <br />as maintenance records, operation logs, etc. provided to Consultant will also be <br />reviewed. Where laboratory analysis of materials is consistent with current regulatory <br />requirements, Consultant shall incorporate such test results into our current <br />assessment. <br />B.1.2.3 Visual Inspection <br />Consultant will perform a visual inspection of the interior and exterior of each Site <br />building, including the roof, focusing on the identification of suspect ACM. Suspect <br />ACM will be grouped into homogeneous areas based on color, texture, use and <br />apparent construction age. The locations, quantities and conditions of each <br />homogeneous area of ACM, as well as an assessment of friability will be recorded on <br />an area by area basis. Each suspect material will be touched, where practical, to <br />determine friability. <br />B.1.2.4 Intrusive Evaluations <br />The inspection team shall select representative areas to perform an intrusive <br />evaluation of void spaces within each Site building or structure. Such inspections <br />shall be made by creating an opening of sufficient size to determine the presence, <br />condition and estimated quantity of suspect ACM within. Void spaces which may be <br />evaluated include locations of suspected pipe or HVAC chases, wall cavities where <br />fireproofing or other ACM is suspected, above finished ceiling systems where ACM is <br />likely to exist, within pipe trenches or within other concealed locations. Although <br />Consultant shall make an attempt to identify all areas of ACM, an exhaustive <br />investigation of void spaces is not included in the scope of services for this project. <br />There may exist conditions which are unable to be identified within the scope of this <br />survey. Consultant shall not patch areas where sampling is performed. The Client <br />may retain the services of an independent contractor or provide maintenance <br />personnel to provide restoration of sampling locations. If the Client elects to provide <br />patching, Consultant shall coordinate activities with the owner's representative, <br />provided that the work may be scheduled while Consultant is on Site for the balance <br />of the assessment activities. <br />B.1.2.5 Photographic Documentation <br />Photographs will be collected to document Site conditions identified by the inspection <br />team. Photographic documentation shall be used illustrate construction type, space <br />characteristics, and to assist in material identification. <br />B.1.2.6 Homogeneous Area Testing <br />Consultant shall collect representative samples of each homogeneous area of <br />suspect ACM identified during the visual inspection and/or plan review. At a <br />minimum, three (3) samples will be collected for each homogeneous area of suspect <br />thermal system insulation. Samples of surfacing materials shall be collected in <br />accordance with AHERA's 3-5-7 rule. Sample locations shall be randomly chosen to <br />the extent possible; however, Consultant shall preferentially collect samples from <br />hidden or obscure locations. Consultant shall additionally attempt to collect samples <br />from areas of pre-existing damage. <br />B.1.2.7 Laboratory Analysis <br />Samples shall be submitted to a laboratory accredited for the analysis of asbestos <br />bulk samples under the National Voluntary Laboratory Accreditation Program <br />(NVLAP). Samples of suspect materials will be analyzed on a first positive stop <br />basis. Analysis shall be performed by Polarized Light Microscopy (PLM), EPA <br />Method 600/R-93-116 (Asbestos in Bulk Building Materials). For materials with low <br />(less than 10%) concentrations of asbestos, a point count quantification of asbestos <br />concentrations can be performed. If additional analyses are required, Consultant will <br />contact the Client for authorization. <br />Exhibit B — Scope of Services Page 3 <br />
