If you believe by using geopiers can eliminate this requirement, provide evidence from the author of the soils report and provide addendum for geopiers inlieu of grade beam in writing.
PC 3rd review comment: Please revise insulated pad footings per soils report recommendations.In your response, verifying with the ground improvement contractor will not supersede the soils report requirements. If you believe by using geopiers can eliminate this requirement, provide addendum in writing from the author of the soils report.Add note to the cover page of the structural plans that “The design of the ground improvement mitigation method to mitigate the effects of liquefaction and for support of the proposed foundation system shall be designed by a licensed professional and reviewed and approved by the geotechnical engineer and the structural engineer in record”.Foundation design shall be reviewed by the geotechnical engineer. Geotechnical report recommendations are considered to be minimum standards. Structural calculations and drawings must meet or exceed said minimum standards. Verification of review may be by a “review stamp” on the foundation plan or by a letter on their letterhead. (1803)PC 2nd comment: In your response: “Foundation plans have been provided to the geotechnical engineer(s) for review”. Please provide evidence of review and approval by the geotechnical engineer.PC 3rd review comment: Please provide evidence of review and approval by the geotechnicalengineer.Retaining wallPlease provide a wall legend and key plan in the calculations, identify the walls calculated, and cross-reference to the details/schedules on the plans. (e.g. elevator pits, garage walls at ramp…)PC 2nd comment: pending.PC 3rd review comment:Missing key plan to cross-reference retaining walls from foundation plan into structural calculation. A recommendation is to provide a 8.5”x11” key plan in the calculation for cross-referencing. (Slipped walls on GS4.1, interior ramp detail 1, 4 on GS1.4)Please indicate page number in the structural calculation content for all retaining wall design.A duplicated sheet GS4.1 is included in the package with incomplete details. Please clarify.Clubhouse / fitnessPlease provide CMU shear wall design, reinforcement, length and details on the framing plan and make cross-reference with the structural connection details.
