Elevator No. 2 analytical finished-entrance envelope placement
Accepted · zero-thickness evidence review onlyW217 supplies an exact symmetric 24'-11" Bay P plan, a 6-foot central paired door, and a separately chained 3'-6" Elevator No. 2 finished entrance. Centering that exact plan on the independently labeled W3 Bay P wall leaves 1.256-foot endpoint residuals and a 1.468-foot held-out door-center residual, both within W3's recorded 2-foot trace uncertainty. The W3 door trace is only 3.9 feet wide and its south endpoint fails the 2-foot check, so it is treated as an incomplete swing-arc trace and is not used to resize the verified W217 leaves. A separate old W3 line classified as the Elevator No. 2 threshold is 6.957 feet from the W217-predicted entrance center and differs in orientation by 89.695 degrees; targeted review confirms it is not the Bay P-parallel entrance plane, so that provisional trace is disputed and excluded. The checked registration places the zero-thickness analytical door leaves and Elevator No. 2 finished-entrance envelope only; it does not establish physical wall, frame, shaft, cab, or equipment geometry.

Full-sheet text and existing reports were read first; the complete sheet and sequential Bay P plan crops were then inspected one image at a time.

The W3 registration is provisional. Bay P wall endpoints and the double-door segment are traced plan controls with a conservative 2-foot uncertainty, not surveyed construction faces.
