Cross-discipline design-contradiction checker for construction drawing sets. Standalone tool broken out from Iron_Bid; a pipeline stage may later fold back into Iron_Bid. Pipeline: PDF->images -> per-sheet assertion extraction -> deterministic clustering by location -> per-cluster reasoning -> report. Includes CLI (cli/run_check.py) and web UI (backend/main.py).

This ASTM standard was withdrawn in 2014, making it obsolete for a project under 2015 codes. The current industry standard is ANSI A326.3, which measures Dynamic Coefficient of Friction (DCOF). Relying on a withdrawn standard may result in the installation of flooring that does not meet the requirements for slip-resistant surfaces under the ADA, TAS, and IBC.", "evidence": [{"discipline": "General", "sheet": "G31.05", "source_text": "STATIC COEFFICIENT OF FRICTION: MIN. 0.6 FOR LEVEL SURFACES, MIN. 0.42 FOR RAMPS PER ASTM C1028 OR ANSI A137.1.", "asserted_value": "min 0.6 SCOF"}], "recommended_resolution": "Update the specification to reference the current standard, ANSI A326.3, and specify a required DCOF value (e.g., >= 0.42 for interior, level spaces expected to be walked upon when wet) to ensure compliance with accessibility requirements for slip-resistant surfaces.", "code_reference": null}, {"issue_id": "VZE_2024_01_G3104_1", "source_stage": "code", "category": "fire_separation", "severity": "high", "confidence": "high", "location": "Specification Section 081113, Sheet G31.04", "disciplines": ["Architectural", "Specifications"], "sheets": ["G31.04"], "description": "Specification section 081113 contains conflicting and potentially incorrect requirements for fire-rated doors. It specifies a '90 minute rated Class C' door, which is a contradiction; Class C doors are 20-minute rated, while 90-minute doors are Class B. It also calls for a '1-hour label' on doors in 1-hour exit corridors, where a 20-minute door is typically required by the IBC. This confusion could lead to the installation of improperly rated door assemblies, compromising life safety.", "evidence": [{"discipline": "General", "sheet": "G31.04", "source_text": "WHERE REQUIRED, INSTALLED FRAME AND DOOR ASSEMBLY SHALL CONFORM TO A 90 MINUTE RATED CLASS C INDICATED.", "asserted_value": "90"}, {"discipline": "General", "sheet": "G31.04", "source_text": "INCLUDE 1-HOUR LABEL ON FIRE RATED DOOR ASSEMBLIES LOCATED AT 1 HOUR RATED EXIT CORRIDORS.", "asserted_value": "1-hour"}], "recommended_resolution": "Revise specification 081113 to align with IBC Chapter 7 requirements for opening protectives.
