Brookview Estates Reconstruction <br /> Ramsey, Minnesota <br />NTI Project No. 18.MSP06855.000 <br /> <br /> <br />1.0Scope of Services <br />Seven borings were in the project area. The scope of services included determining existing bituminous <br />and aggregate base thicknesses, groundwater levels, subsurface conditions, and providing <br />recommendations for site preparation, excavations, engineered fill and compaction, depths of <br />unsuitable soils to be removed, groundwater management, potential difficulties during construction, <br />utility construction, and pavement design thickness. <br />1.1Project and Site Description <br />The project consists of the complete reconstruction of Germanium Street at 173 rd Avenue in Ramsey, <br />Minnesota. NTI was not aware of invert elevations or other design details of the proposed utilities at <br />the time this report was prepared. <br />The pavement sections are proposed to be designed with a 20-year design pavement life. NTI has <br />assumed an AADT value of 600 for these residential streets. <br />2.0Subsurface Exploration Summary <br />NTI performed the subsurface exploration program during the period of September 26, 2018 with a <br />two-person crew using a truck-mounted CME-55 drill rig. Samples were generally collected in <br />dard Penetration Testing (SPT) and Split- <br /> The boring locations and depths were determined by a representative of the <br />City of Ramsey. The boring locations were marked in the field by NTI. The borings terminated at <br />depths ranging from approximately 10.5 to 20.5 feet below the top of pavement. Elevations were <br />determined using a Trimble GeoXH 6000 and rounded to the nearest one-half foot. <br />Please refer to the Boring Location Diagrams and the Boring Logs in Appendix C. <br />Groundwater was observed at depths ranging between 6.5 and 9 feet below the ground surface, <br />correspond to elevations ranging between 876.5 and 872.5. <br />The lack of observed groundwater in the remaining borings is likely due to the short duration for which <br />the boreholes remained open. In addition, the seams of on-site clay and silt laden soils have the <br />potential to be somewhat impervious and conducive to the development of zones of perched water at <br />varying elevations and locations across the project area. Please refer to the boring log included in the <br />appendices. <br />Table 1 summarizes the encountered subsurface conditions encountered. <br /> <br /> <br /> <br />Page 1 of 7 <br /> <br />
