Foothill Blvd. Comment No. Response A To the best our knowledge, the existing foundation is the typical spread footing with the bottom with approximately 12" wide. Our detail is to provide a direct replacement for the existing footing. The house has been on the site over 70 years. The settlement would be minimal by now. In addition, cost is the factor not to do any more than what we propose to do on this report. The owner understands the settlement issue. B See revised plan C 12" is the minimum footing depth. However, we will provide • observation during the trenching (see revised plan). It will be our discretion to instruct the contractor excavate deeper for the foundation trench. We try to avoid pier-and-grade beam approach to minimize the different settlement. D Our field observation indicates that there is not concentrated load to the wall footing. However, we will check again during the construction. Cr, 20 SUBMI TTq� / OFFM� • 1001.John Way • Cupertino,CA 95014 • Tel:(408)305-995.

Foothill Blvd, Cupertino, CA Dear Ms. Liu, At your request, we visited the subject site to review the existing foundation condition. Due to lack of accessibility to the foundation area, we only looked at the foundation from outside of the house. In addition, we reviewed the inspection report by Edward's Construction. Our review on the report was focused on the foundation portion only. All items other than foundation will be excluded from this report. Here is our conclusion: • The report indicates several deficiencies at the existing foundation. However, there is lack specific how to repair or replace the foundation. • The air epoxy injection at the crack footing is acceptable. This approach will seal the crack and prevent further corrosion to the existing reinforcement. • Regarding foundation anchors, the report does not specify the exact type of anchor for secure the sill plate to the concrete. • For the interior piers, we do not have recommendation at this point. • RECOMMENDATION • The foundation at the right side of the house should be replaced per attached detail S1 • Replace 6'-0" foundation where existing foundation experience excessive settlement. We noticed a 6" settlement at the left hand of the house. This approach will not guarantee to prevent future settlement. However, it provides a positive support for the structure. • Air epoxy injection at all cracks • Install new %2"x 10" wedge anchors @ 48" oc (with 6" embedment) at all existing wall foundations. These anchors only resist the shear force generate by the wind or seismic activity. They will not resist the uplift load due to wind or earthquake load. In Edward's report, section 4, it indicates the anchor bolts will transfer uplift loads to the foundation. This is incorrect. • Additional inspection is recommended when your contractor open the floors and walls. If you have any questions, please feel free to give us call. oQFtOFESS/Op. ,� Sincerely fjQ���aOHUN� Fyi N'No 52160 s� m even C. Chu, MSPE If • Cc: Thomas Liu & Associates 1 10615 John Way .
