A photograph may show a floor, step, mat, display, curb, threshold, handrail, doorway, aisle, or spill without showing its dimensions or relationship to the route through the area. A diagram may look precise even when its measurements, reference points, scale, date, or creator are unknown. The record should make those limits visible.

A measured-scene record should connect every dimension, level, fixture, sightline, photograph, and diagram label to a date, method, reference point, observer, source file, and stated uncertainty.

Identify the exact place and observation date

  • Property name, address, building, floor, room, aisle, entrance, parking area, stair, landing, walkway, or other location described precisely
  • Date and time of the fall, date and time of each observation, access provider, people present, and weather or lighting condition actually observed
  • Scene reported unchanged, changed, repaired, cleaned, rearranged, blocked, demolished, or unknown, with the source for that status
  • Property plan, lease exhibit, permit drawing, store layout, maintenance diagram, or later field sketch labeled by source and version

Choose stable reference points before measuring

  • Fixed wall corner, column, doorway edge, drain, curb joint, stair nosing, permanent fixture, or other reproducible reference point
  • Temporary mat, cart, cone, product display, chair, debris, liquid, or movable object identified as temporary rather than used as the only datum
  • Horizontal direction, vertical reference, floor or grade level, north or another orientation, and drawing origin stated
  • Measurement device, unit, resolution, calibration information if known, person measuring, person recording, and repeat measurement

Record dimensions without adding a technical conclusion

  • Width, length, height, depth, elevation change, slope reading, stair geometry, clearance, distance, and position placed on separate lines
  • Start and end points for each measurement shown in a photograph or sketch rather than described only as “the step” or “the area”
  • Observed value, estimated value, value copied from a document, and value calculated later identified separately
  • Unreachable point, obstructed view, uneven edge, range, measurement conflict, and missing dimension retained as limitations

Separate firsthand observation from inference

North Carolina Rule of Evidence 602 addresses personal knowledge. A person may document what the person saw, measured, or photographed, but should not attribute a condition to a date the person did not observe without identifying a separate source.

Rule 701 addresses specified opinion testimony by lay witnesses, while Rule 702 addresses qualified expert testimony. A field record can preserve dimensions and observations without deciding whether a condition violated a technical standard, caused the fall, or should have been changed.

Tie photographs to the diagram

  • Original filename, creation information, photographer, camera position, direction, height, field of view, and item or dimension depicted
  • Overview, intermediate view, close view, scale reference, measurement endpoints, and reverse angle indexed by diagram label
  • Original image preserved; working copy with arrows or labels stored separately and linked back to the original
  • Panorama, perspective distortion, wide-angle setting, zoom, crop, exposure change, or stitching disclosed when relevant to interpretation

Rule 901 addresses authentication or identification as a condition of admissibility. Recording who created a diagram or image, when, how, from what observations, and what later changed assists a reviewer but does not make the item admissible or prove the condition existed at the event time.

Create separate as-observed and reconstructed layers

  • Layer showing only fixed features and measurements personally observed on the inspection date
  • Layer showing temporary objects or conditions supported by event photographs, video, witness accounts, or business records
  • Claimed body position, direction of travel, object contact, and fall sequence attributed to the person or source supplying it
  • Alternative placements, disputed locations, and unknown areas retained instead of merged into one definitive drawing

Preserve every diagram version

  • Draft number, creator, date, source measurements, changes, correction reason, reviewer, and file location
  • Scale drawing, not-to-scale sketch, photograph overlay, three-dimensional model, and demonstrative image labeled accurately
  • Original field notes and source files preserved beside any cleaned drawing or presentation copy
  • Later property change, additional measurement, witness correction, or source conflict added as a dated revision rather than overwriting the earlier record
