Box 2706 Vero Beach, FL 32961 Re: 1928 Lynx Drive Lot 30 Hutchinson Island, Florida KSM Project #: 210106-b2 Dear Sir: As requested, KSM Engineering & Testing has performed a subsurface investigation at the above referenced site. The data gathered during the investigation, together with our geotechnical related opinions, are included in this report. Site Description: At the time of drilling, the riverfront site was flat with a slight slope toward the water. There was a building pad constructed on the site, consisting of approximately 2 to 3 feet of site fill. Site Investigation: The site investigation program consisted of performing four (4) Standard Penetration Test (SPT) borings within the area of the proposed footings for the proposed structure. The borings were terminated at depths of 10 to 14 feet below existing grade on the site at the time of the investigation. These tests were performed in order to verify that the soil densification had been achieved through cement grouting under pressure. The locations of the borings were specified by the client in the field and the approximate locations are indicated on the attached boring Location Plan. The SPT borings were completed in general accordance with procedures described in ASTM D1586. The records of the soils encountered, the penetration resistances and groundwater level are shown on the attached logs. Engineering Evaluation and Conclusions: We performed borings in the proposed footing areas in order to verify that the site had been properly stabilized through cement grouting under pressure, the results for this investigation are as follows: 1928 Lynx Drive Lot 30 Hutchinson Island, Florida KSM Project #: 210106-b2 Page 2 of 2 Location B-1 – The soils in this area were found to still be very loose from 6 to 9 feet below existing grade at the time of the investigation. Nevertheless, a slight improvement was recoded in the loose soil strata in comparison to the previous investigation (report dated 1/6/2021). Notably, there was no “zero blow count” material encountered in the boring. Locations B-2 to B-4 – The soils in these areas indicated significant and measurable improvement of the soil density. It is KSM’s professional opinion that the subsurface soils are sufficient for the proposed structure with the use of a steel reinforced “waffle type” structural slab. The site preparation work and the foundation should be conducted and constructed in accordance with our previous soils report, dated January 6th, 2020. Closure: This report has been prepared in accordance with generally accepted soil and foundation engineering practices based on the results of the test borings and the assumed loading conditions. No warranties, either expressed or implied, are intended or made. This report does not reflect any variations which may occur between the borings. If variations appear evident during the course of construction, it would be necessary to re-evaluate the recommendations of this project. Based upon our subsurface investigation at the above-mentioned project location, the reliance of the recommendations presented within this signed and sealed report is predicated on KSM representative’s involvement to verify that not only have the soils been prepared following the indicated recommendations, but the foundations are installed in compliance within the parameters indicated. The Structural Engineer of Record is responsible for confirming that the estimated capacities provided are adequate for the anticipated loading. If additional capacity is required, KSM is to be notified so that our recommendations can be amended as required. Environmental conditions, wetland delineation, water quality, and municipal requirements are not a part of this report. We are pleased to be of assistance to you on this phase of your project. When we may be of further service to you or should you have any questions, please feel free to contact us. Respectfully, _______________________ _______________________ Christopher S. LeBrun, E.I.
