Monthly Report <br />Regulatory Approvals <br />County TCAAP Redevelopment Project <br />www.tcaap.net <br />November 2013 <br />The construction team will be submitting a series of Response Action Plans (RAPs) for specific <br />building sites. These are required by the MPCA and, once approved, will allow a framework for <br />further remediation at each site. <br />Demolition and Remediation Update <br />Asbestos removal work continues on Building 502. Demolition is slated for early 2014, but <br />portions of the building may be taken down sooner. So, expect to see changes from Highway <br />96. This is the last building to be demolished. It represented the final production facility in a <br />complex that employed tens of thousands over several decades. It is interesting to know that <br />other production buildings will soon populate the site. <br />Winter Schedule <br />Bolander plans to work throughout the winter, particularly in the remediation of Building 502, <br />and to remove large portions of foundations left on the site. Subgrade work will continue as <br />long as crews can dig. Some 300,000 tons of concrete remain in building foundations where <br />those buildings were removed by the Army prior to sale. The rail lines and ties have been <br />removed; the rail bed has frozen and will be taken up after the spring thaw. <br />Unforeseen Condition <br />The only real "surprise" found during construction activity thus far occurred at the ballistics <br />testing range, Building 508, which is next to its practical twin facility, Building 108. Sometime in <br />the 1970s, Building 508 was to have been removed from the property. This summer it was <br />assumed to be removed as there was no evidence of the building slab at grade. There was just <br />a meadow with some small trees. While removing utilities in the area, the contractor <br />unearthed a slab with foundations and a partial basement under several inches of top soil. It <br />seems that the basement area was filled with debris from the general demolition process. <br />Unfortunately, this material contained asbestoses insulation mixed with soil and rubble.
