City of Lake Elmo <br />CSAH 14 Watermain Improvements, City Project No. 25X.140463 <br />Revision 1.0 <br />Proposal 10002208_001 <br />November 13, 2025 <br />Braun Intertec Page 2 <br />Depending on access requirements, ground conditions or potential utility conflicts, our field crew may alter <br />the exploration locations from those proposed to facilitate accessibility. <br /> <br />Our drilling activities may also impact the vegetation and may rut the surface to access boring locations. <br />Restoration of vegetation and turf is not part of our scope of services. <br /> <br />Staking <br />We understand Bolton & Menk, Inc. will stake prospective subsurface exploration locations. We request that <br />you provide CAD files indicating the boring locations and elevations for this project. <br /> <br />Utility Clearance <br />Prior to drilling or excavating, we will contact Gopher State One Call and arrange for notification of the <br />appropriate utility vendors to mark and clear the exploration locations of public underground utilities. You, or <br />your authorized representative, are responsible to notify us before we begin our work of the presence and <br />location of any underground objects or private utilities that are not the responsibility of public agencies. <br /> <br />Permits <br />We will obtain a right-of-way permit with the Washington County (County) prior to beginning our fieldwork. <br />Our proposal includes permit fees for the County. <br /> <br />We assume the County permit will include a work hour restriction within public right-of-way of 9:00 AM to <br />3:00 PM during weekdays and our scope and fees account for this restriction. <br /> <br />Traffic Control <br />Based on aerial images from Google Earth we anticipate performing the borings within the existing turn lanes <br />and/or roadway shoulders. Therefore, we anticipate the exploration locations will require Lane shifts, turn <br />lane or shoulder closures to alert motorists to our work area. We are including fees for a subcontractor to <br />provide signage for closure of shoulders/turn lanes or lane shifts, as needed. <br /> <br />Pavement Coring <br />As requested, we will core the pavement and record bituminous and aggregate base thicknesses at each of <br />the proposed soil boring locations within the existing roadway. Photographs of the recovered pavement cores <br />will be included in the project geotechnical report in the form of a pavement core log. <br /> <br />Penetration Test Borings <br /> <br />As requested, we will drill four standard penetration test (SPT) borings for the project to depths of <br />approximately 14 1/2 feet below existing grade. We will perform standard penetration tests at 2 1/2-foot <br />vertical intervals to a depth of about 15 feet, and at 5-foot intervals at greater depths, if required. <br /> <br />The figure below shows an illustration of the proposed boring locations.
