City of Arden Hills 2028 Pavement Management Project Proposal QTB221496 September4, 2025 We also understand from conversations with Bolton & Menk, Inc. that Shoreline Lane is experiencing settlement around the utility manhole structures. Depending on soil boring exploration, a M&O or FDR may not be suitable, and a full reconstruction may be needed to correct either soft, loose or compressible soils. Purpose The purpose of our geotechnical evaluation will be to characterize subsurface geologic conditions at selected exploration locations, evaluate their impact on the project, and provide geotechnical recommendations for the design and construction of the 2028 Pavement Management Project. Scope of Services We propose the following tasks to help achieve the stated purpose. If we encounter unfavorable or unforeseen conditions during the completion of our tasks that lead us to recommend an expanded scope of services, we will contact you to discuss the conditions before resuming our services. Site Access Based on aerial photographs, it appears that the site is accessible to a truck mounted drill rig for soil borings and a pick-up truck mounted with a coring machine for the pavement cores. We assume there will be no cause for delays in accessing the exploration locations. We are not including debris or obstruction removal, grading of navigable paths, or snow plowing. Depending on access requirements, ground conditions or potential utility conflicts, our field crew may alter the exploration locations from those proposed to facilitate accessibility. Staking We will stake prospective subsurface exploration locations, as selected by Braun Intertec, and obtain surface elevations at those locations using GPS (Global Positioning System) technology. In order to link the GPS data to an appropriate reference, we request that you provide CAD files indicating location/elevation references appropriate for this project, or give us contact information for the consultant that might have such information. 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 exploration 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. ROW Permit and Work Hours We will obtain a right-of-way (ROW) permit through the City of Arden Hills (City) prior to beginning our fieldwork. We assume the City will waive permit fees as we will be completing the work for them. We assume Braun Intertec Page 2
