South Bend Redevelopment Commission Ignition Park ACM Demolition Proposal — Batch 3 1/09/2012 Page 3 I w takes into account any multiple structures at combined addresses, except as noted for commercial buildings. This fee will not be exceeded without prior written justification and approval. Analyses of samples for suspect asbestos- containing materials (ACM) will be invoiced at the stated unit costs. The number of suspect asbestos containing materials (ACM) per structure based on our previous experience with structures of similar size, age and construction is expected to average 6 by PLM per structure. This includes brittle, potentially friable Category H suspect materials. We intend to assume that Category I non - friable materials (resilient flooring, flooring adhesive, asphalt roofing, gaskets) are ACM and do not anticipate the need to sample these at this time. These can remain with the structures for demolition. Older linoleum consisting of two separable layers will be considered Category II potentially friable and sampled if encountered. The only Category I material that will be sampled is resilient flooring attached to concrete, to allow the concrete to be recycled. The actual number of samples needed will be determined in the field. It is not expected to vary greatly from the number quoted. The Commission will be billed for the actual number of samples collected. BASIS OF PROPOSAL The above pricing is based on the following assumptions: • Commission to provide ready access to each structure • Commission to assure that each structure is unoccupied Ready access includes keys or the typical chipboard or plywood sheeting over doors fastened with hex head or #2 square drive multipurpose screws. Locked doors either alone or underneath this sheeting are not considered "ready access ". IDEM allows the demolition of residences with non - friable Category I and II materials in place, except when intentionally burned. We propose to assume such materials to be ACM and document them as such, including their quantities, on the IDEM Notification and in our survey reports. Although it rarely occurs, severely water - damaged resilient flooring, normally a Category I non- friable material even for demolition, may be encountered and need to be classified as potentially friable for demolition. A confirming analysis for this type of material will be needed and is done by TEM. TEM analysis for Category I flooring on concrete is included in this pricing, but if potentially friable Category I flooring is encountered the need for this additional analysis will be brought to the Commission's attention for action. Although it rarely occurs, occasionally a friable suspected ACM sample shows greater than I% asbestos. In this situation additional confirming samples will be collected in an effort to save the large expense of removing this material prior to demolition. Analysis will be by TEM at the quoted unit price. The number of confirming samples will be determined in the field, based on the material involved. TEWE OF COMPLETION • from receipt of the formal Notice -to- Proceed to completion of the field survey -- 2 weeks • from completion of the field survey until submission of the Survey Report and IDEM Notification -- 2 weeks
