Audit findings

Cost effect uses starting assumptions: open deck $100/sf, 20% soft costs and 8% contingency. Enclosed area, unit areas, rents and unit counts are unchanged. These drawings do not establish legal bedroom status, final island / fixture clearances, accessibility, egress or structural / MEP approval. Earlier full-room sketches must be reconciled with the revised wet zones.

Homes and service bays align where drawn. Dashed riser reservations under lobbies / unfitted space still need a ground service route. No ground income is added at Evans.
