Quality Assurance Testing Proposal Lexington Avenue Sidewalk, Roseville, MN February 5, 2026 AET ProposalNo. P-0050437 cylinders) are required once per every 300 cubic yards of each type of concrete placed each day; the cylinders will be retrieved the following day for curing and testing in our laboratory.The 3 cylinders are to be tested at 28-days.We are proposing to cast sets of 5 cylinders, with compressive strength testing as follows: 1 at 7 days, 3 at 28 days, and the 5th cylinder will be held in reserve for future testing if the 28-day strength requirement is not met. We have assumed Citypersonnel will be compiling the concrete batch tickets, certificates of compliance, and AET’s field test results of the plastic concrete, which we will provide each day we are on-site performing testing services. REPORTING AET staff will prepare reports for the Cityto review.These reports will include the results of our field and laboratory testing as performed per the 2023 MnDOT SMCand testing frequencies referenced in the project documents.AET will complete the Preliminary Grading and Base Report and the Final Grading and Base Report,once provided with final project quantities.Daily field reports will also be preparedand made available upon request. ESTIMATED FEES Our services will be provided on a unit cost basis according to the unit rates provided in the attached Materials Testing Estimate.Our invoices will be determined by multiplying the number of personnel hours or tests by their respective unit rates.The rates are from the annual fee schedule for 2026projects. We have estimated a “minimum required estimate” for the project which estimates the tests needed to satisfy the requirements as defined in the 2023 MnDOT SMCand the project documents.The “likely needed estimate” is the cost that we anticipate will be required to complete the previously described testing services, based on our experience,and assumed scheduling of the project.Therefore, we propose a budget cost estimate using the “likely needed” estimate for the scope of services for the project as outlined in this proposal.Our “likely needed” estimated fee is $6,555.00.We refer you to the attached Materials Testing Estimate as reference to how we arrived at this estimated cost. We caution that this is only an estimated cost. Often, variations in the overall cost of the services occur due to reasons beyond our control, such as weather delays, changes in the contractor’s schedule, unforeseen conditions,or retesting.These variations will affect the actual invoice totals, either increasing or decreasing our total costs for the project from those estimated in this proposal.If more time or tests are required, additional fees may be needed to complete the Page 3of 5 Qbhf!95!pg!2:7
