AET Proposal for 2026 Geotechnical and Construction Testing Services City of Ramsey, Minnesota February 16, 2026 Construction Materials Testing During construction AET will provide experienced MnDOT certified technicians for construction materials testing. Our technicians will be scheduled for density testing, concrete testing, and bituminous testing on an on -call basis to perform the work. AET will provide a field engineer to perform any Excavation Observations if unsuitable soils are encountered during grading of the roadway and will provide a technician to perform soil density testing of the backfill materials used during the sanitary sewer, watermain and storm sewer installation. Our technician will also obtain soil samples as needed for laboratory proctor and density testing. Upon completion of the utility installation our technician will provide soil density testing for the subgrade of the roadway as well as DCP testing for the aggregate base section. If any test results are out of specification City staff will be notified. During the placement of concrete for curb and gutter our technician will verify the proper mix design upon delivery and perform plastic concrete testing for the mix being placed. Our technician will perform temperature, slump, and air entrainment testing of the concrete and verify that all test results meet City and project specifications. If any test results are out of specification City staff will be notified immediately on site. A total of five cylinders will be cast with each test performed (or every 100 cubic yards placed). One cylinder will be tested for compressive strength at 7 days, three cylinders will be tested at 28 days, and one cylinder will be kept as a hold. If the 28 day average compressive strength does not meet specifications then the hold cylinder will be tested at 56 days. During bituminous paving operations our technician will be available on site to observe rolling procedures and establish a rolling pattern with the paving crew. Our Project Manager will coordinate with City staff and the bituminous plant to obtain laboratory split samples of the bituminous mix being placed. Upon completion of paving our Project Manager will prepare the MnDOT coring log for City staff to review, once approved we will mark the cores on the roadway. After coring is completed AET staff will transport the bituminous cores to our St. Paul laboratory for testing and will provide the City with the testing results once completed. All test reports will be published via Construction Hive by the Project Manager and will be distributed to City inspection and administration staff, as requested. Our estimated fee schedule for construction materials testing can be found in the Appendix. KEY PERSONNEL AET is fully staffed and equipped to complete the scope of work for City of Ramsey projects and our lead and support personnel hold the certifications and licenses required to perform their work. Our proposed team includes staff from our Albertville office with support from the St Paul Office, as needed. Proposed team titles and roles are shown in the organizational chart below and the qualifications and experience of key staff in Geotechnical and Environmental services are summarized in bios on the following pages. More detailed resumes are included in the Appendix. 9
