The Mark at Eugene January 6, 2026 <br />Geotechnical Investigation and Seismic Hazard Study 17 Project No.: 2251077 <br />Eugene, Oregon Landmark Construction, LLC <br />DESIGN REVIEW/CONSTRUCTION OBSERVATION/TESTING <br />Foundation Engineering should be provided the opportunity to review all drawings <br />and specifications that pertain to site preparation, foundation construction, and <br />pavements (if any). Site preparation will require field confirmation of the suitability <br />of the foundation soils and the depth of site stripping under slabs and foundations. <br />Mitigation of any subgrade pumping will also require engineering review and <br />judgment. That judgment should be provided by one of our representatives. Frequent <br />field density tests should be run on all engineered fill. We recommend Foundation <br />Engineering be retained to provide the necessary construction observation. <br />VARIATION OF SUBSURFACE CONDITIONS, USE OF THIS REPORT, AND WARRANTY <br />The analysis, conclusions, and recommendations contained herein assume the soil <br />profiles and the groundwater level encountered in the explorations are representative <br />of the site conditions.

No changes in the enclosed recommendations should <br />be made without our approval. We will assume no responsibility or liability for any <br />engineering judgment, inspection, or testing performed by others. <br />This report was prepared for the exclusive use of Landmark Construction, LLC and <br />their design consultants for The Mark at Eugene project in Eugene, Oregon. <br />Information contained herein should not be used for other sites or for unanticipated <br />construction without our written consent.
