Summary

CORNAV combines architectural drawings, scene graphs and changing exclusion zones for navigation on active construction sites.

CORNAV aligns two-dimensional CAD plans with an open-vocabulary scene graph, translates project schedules into time-varying constraints and screens hazardous requests before planning. An A* planner enforces mandatory exclusion zones. In an office and a real construction site, the authors report task success rising from 13.0 to 72.2 percent over semantic retrieval alone, with schedule awareness eliminating hard-zone violations in those tests. The result supports construction-specific context in navigation; it is not general safety certification for changing worksites.

Corrections

: Publication note: This October 4 edition was reconstructed on October 5 after the workstation was offline. It uses original October 2 submissions from the standard Sunday-evening arXiv release, rather than claiming those papers were available for the missed 9 AM run. The date and 9 AM publication slot preserve archive chronology; October 5 developments are excluded. The September 27 Invention Desk is carried over because its replacement was generated October 5.
