City of Centerville Proposal for Preliminary Geotechnical Services AET Proposal No. 01-20372 February 18, 2019 Page 3 of 4 FEES Our services will be invoiced as a Jump sum cost. Based on the scope of services presented in this proposal, including installing the temporary piezometer and the extra trip for removing it, our not- to-exceed lump sum cost will be $4,450.00. This amount includes a$200.00 budget for laboratory testing of soils and the necessary MN Department of Health filing fees(see below). If soil conditions dictate that additional drilling is needed beyond our estimated boring depths, due to poor conditions or to evaluate other areas,this will be invoiced at a unit rate of$27.00 per linear foot. We will contract you regarding additional work, and receive your authorization to proceed, prior to performing additional services. If additional mobilizations of the drill crew and equipment are needed because of the additional drilling,these will be invoiced at a unit cost of$325.00 per trip. PRIVATE UNDERGROUND UTILITIES Before we drill, we will contact Gopher State One Call to locate public underground utilities. Gopher State One Call does not currently charge for this service; however, they will not locate private underground utilities or structures. Examples of private utilities include, but are not limited to, propane and some gas lines, sewer laterals, sprinkler systems, site lighting, and electric and data lines between buildings. It is the responsibility of the client and/or the landowner to clear underground private utilities,if any,in the vicinity of the boring locations. MINNESOTA DEPARTMENT OF HEALTH REGULATIONS AND FEES Effective July 1, 2017,the Minnesota Department of Health(MDH)has changed the borehole sealing and notification requirements. For sites where borings are drilled to a depth of 15 feet or deeper, all licensed drilling companies are required by law to submit written notification to the MDH prior to drilling, along with a fee of $75. If one or more of the boring depths vary by 25 feet, or more, the MDH requires an additional written notification and fee of $75 per boring. Projects that span multiple properties will require multiple notifications. The NIDH also requires that these borings be grouted and that a Sealing Record be submitted to the MDH, with a copy to you, after the borings are completed. The above fee estimate for our geotechnical services includes the MDH fee for the proposed scope of drilling; however, because final boring depths can change, for example, due to possible unanticipated poor soil conditions, the final MDH fee(including an administrative charge of$65 per notification)will be added, if necessary, to our final invoice to you. The MDH Sealing Record requires the Property Owner name and mailing address (the Property Owner will also receive a copy of the Sealing Record). PLEASE PROVIDE THIS INFORMATION BELOW. 128
