Loose or otherwise disturbed soils should be removed from new foundation locations using <br />hand tools prior to the placement of grout. Disturbed soil not removed from new footing <br />excavations prior to placement of grout could result in footing settlements. All footing areas <br />should be observed by AESI prior to placing grout to verify that the design bearing cap wity of <br />the soils has been attained and that construction conforms to the recommendations contained in <br />this letter. <br />Conclusion <br />In our opinion, the undermined footings can be remediated to be functionally equivalent to the <br />pre -washout conditions using the approach described herein. <br />Analysis of slope stability and recommendations for slope mitigation, repair of the pool, and <br />site drainage are beyond the scope of authorized services. Additional geotechnical services or <br />mitigation of geologic hazards can be provided as part of an additional scope of services. <br />We have enjoyed working with you on this study and are confident that our recomr,tc; ^.adon-s <br />will aid in the successful resolution of this claim.
