1289 Deerwood Dr - Wilson Final Engeering Report September 25, 2020 Libby Montreuil Boulder Images Incorporated 14555 South Robert Street Rosemount, MN 55068 RE: Final Report - Boulder Retaining Walls Project Location: 1289 Deerwood Drive, Eagan, Minnesota Project No. 19-427 Dear Ms. Montreuil: This letter is being sent per your request regarding the recently completed boulder retaining walls at the above listed property. This evaluation is based on: a site visit performed by me on July 2, 2020; a site visit performed by me on September 24, 2020; verbal statement by you regarding construction means and methods; and retaining wall design information prepared by me dated November 6, 2019. Based on my site visits and the other information listed above, the retaining walls appear structurally stable and in general conformance with the Retaining Wall Drawings as prepared, as well as boulder retaining wall industry standards. Typical construction details such as use of drainage elements appear to be followed correctly. As is normal for boulder retaining walls of this type, some seasonal and long-term wall movement and backfill soil settlement should be expected. I recommend that concentrated areas of surface water be directed away from the walls. Scope of Service and Limitations The purpose of this inspection and report is to evaluate the condition of the recently constructed or partially constructed retaining wall. The report is not to be considered a guarantee of condition and no warranty is implied. Our observations are non-destructive, and limited to those portions of the site/wall that could be visually examined without excavation. Our scope of services did not include an exhaustive technical investigation. No material sampling, analytic tests, precise measurements or engineering calculations were performed. This includes but is not limited to: compaction testing, soil sampling, global stability calculations. We did not determine whether the wall and its operation or use conform to any city codes, or regulations, or restrictions that may be enforced within the jurisdiction. For construction phase services, it is understood that the Contractor, not ENGINEER, is responsible for the construction of the project, and that ENGINEER is not responsible for the acts or omissions of any contractor, subcontractor or material supplier; for safety precautions, programs or enforcement; or for construction means, methods, techniques, sequences and procedures employed by the Contractor. As Professional Engineers, it is our responsibility to evaluate available evidence relevant to the purpose of this inspection. We are not, however, responsible for conditions that could not be seen or were not within the scope of our service at the time of the inspection. If additional documentation or information is made available for review, I reserve the right to amend or add to the opinions and observations presented in this report. See also, Terms and Conditions below. This evaluation was performed using the design guidelines presented in the third edition of the “Design Manual for Segmental Retaining Walls” (DMSRW) published by NCMA in 2009. If soil conditions, proposed layouts, or other design parameters vary from that assumed, a revised analysis might be 1289 Deerwood Drive, Eagan, Minnesota July 25, 2020 Page | 2 needed. If additional documentation or information is made available for review, I reserve the right to amend or add to the opinions and observations presented in this report. Please call me if you have any questions or need more information. Thank you. Sincerely, Paul Schimnowski, PE MN PE# 40126 I hereby certify that this plan, specification, or report was prepared by me or under my direct supervision and that I am a duly Licensed Professional Engineer under the laws of the State of Minnesota.
