AET Proposal for 2026 Geotechnical and Construction Testing Services <br />City of Ramsey, Minnesota <br />February 16, 2026 <br />Washington County <br />AET has worked on many projects with the County, providing Geotechnical, Materials Testing, and <br />Environmental services. <br />County Contacts <br />Andrew Giesen -- 651-430-4336; andrew.aiesennco.washinaton.mn.us <br />Erin Blaylock — 651-430-4384; erin.blavlockc co.washinaton.mn.us <br />Allan Brandt — 651-430-4348; allan.brandt c(r�.countv.washinaton.mn.us <br />AET Staff: Thomas Evans, Megan Hoppe, Justin Staker, Ryan Schaefer <br />UNDERSTANDING OF THE SCOPE OF WORK <br />We understand that the scope of work includes completing geotechnical and construction testing <br />services, as directed, on a variety of municipal infrastructure projects within the City of Ramsey, on an <br />as needed basis. Our understanding of the scope of work, and ability to provide responsive and flexible <br />scheduling, will allow us, and our main point of contact, to serve the City of Ramsey and respond to <br />client needs and unforeseen circumstances within 1 hour. <br />AET has over 50 years of experience providing geotechnical and testing services to municipalities and <br />counties across Minnesota. Our Geotechnical Team offers complete geotechnical services ranging <br />from drilling, in -situ testing, and laboratory testing to engineering design and consultation. Our <br />Construction Services Team provides field and lab construction materials testing, Special Inspections, <br />and bituminous and pavement testing. Our Saint Paul materials testing laboratories are AASHTO <br />accredited. <br />Geotechnical Services <br />AET conducts soil borings, with multiple drill rigs, on a daily basis. Our drillers have many years of <br />experience drilling in a wide range of soil types, soil stiffness/density conditions, and groundwater <br />conditions. Drilling methods include hollow and solid stem auger drilling, mud -rotary drilling (required in <br />granular soils below the water table), and specialized casing advancements when overhead space <br />limits conventional practice. To match the correct rig with access needs, we use truck vehicles of <br />varying size, all -terrain vehicles (both rubber -tired and tracked), and several sizes of portable rigs. AET <br />also performs piezocone penetration testing and seismic piezocone testing. <br />AET routinely incorporates hydrologic/hydrogeologic considerations into our environmental and <br />geotechnical programs. Having environmental well contractors, licensed by the Minnesota Department <br />of Health (MDH), on staff provides us with the expertise and flexibility to install monitoring wells or <br />piezometers, rather than subcontracting for well installation. Our team of drillers have many years of <br />experience installing monitoring wells in varied soil, bedrock, and groundwater environments. <br />Our professional engineering staff prepares Geotechnical Exploration Reports based upon our soil <br />borings and laboratory testing of samples. These reports present our geotechnical recommendations <br />for a large variety of projects including buildings, roadways, bridges, and retaining walls. The reports <br />are prepared by experienced engineers with principal level review by a Professional Engineer licensed <br />in the State of Minnesota. <br />5 <br />
