All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval. 1 STRUCTURAL COMMENTS CALCULATION Provide diaphragm design to make sure the maximum diaphragm dimension ratio (4:1) is within code limit per IBC table 2305.2.3. Provide design, detail and calculation for each diaphragm chord, collector, drag force, boundary element, blocking, and strap, especially at the "L shape" reentrant corner. Please indicate the assumed dimension of diaphragms in your calculations. DRAWINGS 2.

Sheet S 2, It appears the 2- ft long shear walls does not comply with the maximum shear wall aspect ratio per IBC table 2305.3.3. Please clarify. 8. Sheet S 3. Detail 3 9' top restrained end retaining wall. If the retaining wall is designed with the assumption of top and bottom restrained, then, the top reaction forces must transfer to the floor diaphragm or floor -framing members, which will increase the shear forces for diaphragm and shear wall design. All load paths must complete. Please resolve. 6 Additional corrections may be required following receipt of corrections and additional information as requested. Your plans are being reviewed concurrently with the Building Department, Fire Department, Zoning Department and Public Works Engineering.
