[Comment Resolved]
Typical to all drawings, EOR to provide/show drag connection detail(s) at the end of shear wall(s) to all line of lateral resistant elements.
[Comment NOT Resolved – Shear transfer (Drag detail) does not indicate at end of shear wall, i.e. Sheet 1.2 grid line 2A, 10. SEOR to verify all locations at all buildings;
Usually, maximum drag forces occur at end of shear wall; if no drag detail indicate, then identify the shear transfer, and provide calculation to justify the adequacy,
i.e. 1. Sheet S-1.2 grid line 7 at end of 7’3” shear wall near the stair.
2. Sheet S1-1.3 missing drag reference at grid line 2
Further review is required]
[Comment NOT Resolve – shear transfer does not indicate at end of shear wall
i.e. 1) Sheet S1.2, grid line 3 at end of 9’-6” shear wall
2) sheet S1.2, grid line 11 at end of 7’-3” shear wall
3) sheet S1.2, grid line C at end of 4’-6” shear wall

Typical to all drawings, EOR to provide/identify correct drag connection details. Many locations were identify insufficient connection (less than per structural calculation required) or identify on the incorrected location, i.e. away from the end of shear walls

Revise and provide sequential grid line. Typical to all buildings. Revise calculation design callout to match drawing grid. There are missing calculation for the shear wall(s) design

Further review is required due to missing of lateral analysis design from high roof of the shear wall, i.e. holdown reactions will be impacted at the first level. Please provide design and provide holdown devices at the high roof level, typical to all buildings
