Bolton & Menk, Inc. <br />Proposal QTB172950 <br />February 17, 2023 <br />Page 3 <br />greater, the Statutes requires that we seal the boreholes and complete a Sealing Record. If 25 feet or <br />greater, the Statutes also require us to complete a Sealing Notification Form. If the Record or Form are <br />required, we will contact you to discuss the additional fees and sealing requirements. <br />Borehole Abandonment <br />We will backfill our exploration locations immediately after completing the drilling at each location. <br />Minnesota Statutes require sealing temporary borings that are 15 feet deep or deeper. We currently do <br />not anticipate having to seal any of the boreholes. <br />Upon backfilling or sealing exploration locations, we will fill holes in pavements with a temporary patch. <br />Overtime, subsidence of borehole (core) backfill may occur, requiring releveling of surface grades or <br />replacing bituminous or concrete patches. We are not assuming responsibility for re -leveling or re - <br />patching after we complete our fieldwork. <br />Sample Review and Laboratory Testing <br />We will return recovered samples to our laboratory, where a geotechnical engineer will visually classify <br />and log them. To help classify the materials encountered and estimate the engineering properties <br />necessary to our analyses, we anticipate performing moisture content tests and percent passing the #200 <br />sieve tests. We will adjust the actual number and type of tests based on the results of our borings. <br />Engineering Analyses <br />We will use data obtained from the subsurface exploration and laboratory tests to evaluate the <br />subsurface profile and groundwater conditions, and to perform engineering analyses related to structure <br />and pavement design and performance. <br />Report <br />We will prepare an addendum report including: <br />■ A CAD sketch showing the exploration locations. <br />■ Logs of the borings describing the materials encountered and presenting the results of our <br />groundwater measurements and laboratory tests. <br />■ A summary of the subsurface profile and groundwater conditions encountered by the <br />additional borings. <br />■ Discussion identifying the subsurface conditions that will impact design and construction. <br />■ Discussion regarding the reuse of on -site materials during construction. <br />■ Recommendations for preparing utility and pavement subgrades, and the selection, <br />placement and compaction of fill. <br />■ Recommendations for pavement section design for James Avenue. <br />BRAVN <br />INTERTEC <br />
