Analytical ruled-envelope strip count
7 zero-thickness strips; preview only7 count
Vertically project the registered W3 west segment only to the second-floor datum, then connect matching west cardinal edges of independently registered upper-floor traces. No vertical wall face, thickness, opening cut or physical construction is implied.
Drawing notation: FIRST FLOOR PLAN
Existing W3 enclosed-floor outer trace reused; not reopened for this derivation. The Madison loading indentation is retained as five separate curtain segments.
Drawing notation: SECOND FLOOR PLAN
Existing W4 outer-envelope trace; not reopened for this derivation.
Drawing notation: THIRD FLOOR PLAN
Existing third-floor outer-envelope trace; not reopened for this derivation.
Drawing notation: FOURTH FLOOR PLAN / HEATING AND LIGHTING
Existing provisional MEP-underlay outer trace; not reopened and not treated as an accepted architectural wall face.
Drawing notation: FIFTH FLOOR PLAN
Existing W7 outer-envelope trace; not reopened for this derivation.
Drawing notation: SIXTH FLOOR PLAN
Existing W8 outer-envelope trace; not reopened for this derivation.
Drawing notation: SEVENTH FLOOR PLAN
Existing seventh-floor outer-envelope trace; not reopened for this derivation.
Drawing notation: EIGHTH FLOOR & ATTIC PLAN
Existing W10 outer-envelope trace; not reopened for this derivation.
