Bolton & Menk, Inc. Proposal QTB182081 July 27, 2023 Page 2 We will apply for a permit for obstruction/excavation from Ramsey County for a boring proposed along County Rd E. Staking We will stake prospective boring locations and obtain surface elevations at those locations using GPS technology. For purposes of linking the GPS data to an appropriate reference, we request that you provide CAD files indicating location/elevation references appropriate for this project. Utility Clearance Prior to drilling or excavating, we will contact Gopher State One Call and arrange for notification of the appropriate utility vendors to mark and clear the boring locations of public underground utilities. You, or your authorized representative, are responsible to notify us before we begin our work of the presence and location of any underground objects or private utilities that are not the responsibility of public agencies. Traffic Control Our boring along County Rd E will require flaggers to complete. We have included the cost of subcontracted traffic control in our budget. Penetration Test Borings As requested, we will drill four (4) standard penetration test borings for the project extending them to depths of 10 feet. We will perform standard penetration tests continuously to boring termination. If the borings encounter groundwater during or immediately after drilling of each boring, we will record the observed depth on the boring logs. MDH Notification and Sealing Record Since our planned boring will be less than 15 feet in depth, the Minnesota Statutes will not require that we complete any notifications or sealing records. If we extend any of the borings to a depth of 15 feet or greater, the Statutes requires that we seal the boreholes and complete a Sealing Record. If 25 feet or greater, the Statutes also require us to complete a Sealing Notification Form. If the Record or Form are required, we will contact you to discuss the additional fees and sealing requirements. Borehole Abandonment We will backfill our boring locations immediately after completing the drilling at each location. Minnesota Statutes require sealing temporary borings that are 15 feet deep or deeper. We currently do not anticipate having to seal any of the boreholes. Over time, subsidence of borehole backfill may occur, requiring releveling of surface grades or replacing bituminous or concrete patches. We are not assuming responsibility for re -leveling or re -patching after we complete our fieldwork. Sample Review and Laboratory Testing We will return recovered samples to our laboratory, where a geotechnical engineer will visually classify and log them.
