Barnhart, Jeremy <br /> From: Matt Ledvina <mledvina @landmarkenv.com> <br /> Sent: Tuesday, September 02, 2014 1:36 PM <br /> To: Barnhart,Jeremy <br /> Subject: Fox Haven Commercial Properties <br /> Attachments: SiteExcavationCostEstSeptl4.xls <br /> Jeremy, <br /> Attached please find an estimate for the removal of buried waste debris at the commercial properties in the Fox Haven <br /> area. <br /> It is important to outline the assumptions that go into this middle-of-the-road cost estimate. For the waste removal,we <br /> are assuming that the residential structure is the only former building that had a basement and foundation. We are <br /> estimating the size of the structure at roughly 40x30 feet based on the aerial photo, but the scale cannot be determined <br /> with full accuracy. We estimate the depth of buried debris and foundation to be 8 feet. We assume that the buried <br /> debris has an overall density of one ton/C.Y. Transportation and disposal is estimated assuming the use of the Vonco II <br /> disposal facility and based on recent contractor quotes with adjustment for the relatively short travel distance. If it is <br /> necessary to utilize an MSW-type facility(ie ERL)the unit cost of disposal could triple. Analytical testing may or may not <br /> be needed and would cost an additional $1,000 assuming two representative samples. We assume that soil from the <br /> property is suitable quality and will used for backfill of the excavation. If additional fill soils are needed,additional costs <br /> will be incurred. We assume that the area of excavation and grading will be seeded with a low-cost MnDOT mixture as a <br /> surface restoration. <br /> As discussed,we recommend that the excavation of materials be supervised by a qualified environmental <br /> professional. We also recommend that a "Construction Contingency Plan" be developed to assist the City in dealing with <br /> tanks, hazardous chemicals or other environmental concerns which may be encountered during the excavation work. It <br /> is assumed that the excavation work would be completed in two working days assuming that no contingencies are <br /> required during the course of the project. The costs for environmental contractors is not included in the estimate and I <br /> could provide an estimate for the environmental portion of this work. <br /> I recommend developing a brief project description/spec (ala NAPA) and requesting quotes from a select number of <br /> contractors. I have a contractor list that would be interested in this work. Hope this helps with your planning for the <br /> properties. <br /> LMK. Matt. <br /> Matthew L.
