The place where two walking surfaces meet may include a permanent threshold, carpet edge, tile joint, expansion joint, drain, coating, transition strip, entrance mat, runner, temporary covering, or repair. Its condition can change through movement, moisture, cleaning, traffic, temperature, maintenance, replacement, or later inspection. A useful record identifies the complete assembly and the event-day condition.

A surface file should distinguish the installed assembly, movable item, event-day condition, measured feature, maintenance history, later change, applicable standard, and qualified interpretation.

Identify the complete walking-surface assembly

  • Exact property, building, entrance, room, aisle, landing, walkway, direction of travel, intended route, and fixed reference points
  • Subfloor or base, finish flooring, tile, carpet, pad, adhesive, grout, joint, strip, threshold, mat, runner, coating, drain, and neighboring surface
  • Manufacturer, product, model, lot, material, dimensions, backing, edge treatment, installation date, installer, drawing, specification, warranty, and replacement history when available
  • Whether an item was permanent, fastened, recessed, loose, rented, vendor supplied, moved for cleaning, or placed for a temporary condition

Record the event-day condition before interpreting it

  • Overall approach, reverse view, eye-level view, side view, close detail, fixed reference, and original image sequence
  • Height, width, gap, slope, cross-slope, compression, curl, buckle, separation, wear, movement, saturation, contamination, debris, lighting, contrast, and visibility only as actually observed
  • Moisture source, footprint or wheel pattern, drainage, weather, cleaning, stocking, construction, traffic, warning, barrier, and time of each observation
  • Reported foot placement, contact, body movement, final position, witness viewpoint, and uncertainty kept separate from a later reconstruction

Use repeatable measurements and preserve the method

For each measurement, record the feature, exact endpoints, units, orientation, instrument, resolution, verification or calibration information, person measuring, observer, date, time, surface condition, repeated readings, photograph, and diagram point. Do not measure only the location that produces a selected result, and do not present a recreated or repaired condition as the event-day surface.

Treat accessibility standards as context, not an automatic verdict

The U.S. Department of Justice’s 2010 ADA Standards for Accessible Design include provisions concerning floor or ground surfaces, carpet, openings, and changes in level when their scoping and application requirements are met. The standards do not establish that every property, route, surface, construction date, alteration, or claim is governed by the same provision. Preserve the facility type, route, construction and alteration dates, governing jurisdiction, adopted code edition, plans, permits, and qualified analysis before drawing a compliance conclusion.

Separate maintenance from design and installation records

  • Cleaning method, product, equipment, schedule, sweep or inspection entry, spill response, mat movement, drying, and warning placement
  • Complaint, prior incident, work order, repair, replacement, vendor visit, invoice, warranty claim, inspection, and employee or contractor communication
  • Plan, detail, submittal, product data, installation instruction, change order, punch list, permit, inspection, certificate, and later alteration
  • Who created each record, what area it covers, whether it reflects policy or actual work, and whether a later entry corrected the original

Preserve access and changes through the correct process

In a filed civil action, North Carolina Rule of Civil Procedure 34 addresses requests to inspect, measure, photograph, test, or sample designated property and tangible things within its scope. Rule 45 addresses subpoenas to nonparties, production, inspection, objections, and protections. An inspection protocol should identify the place, people, equipment, method, duration, conditions, samples, potentially destructive steps, restoration, and custody. Informal access and formal discovery are not interchangeable.

Maintain identity and version history

North Carolina Rule of Evidence 901 addresses evidence sufficient to support a finding that an item is what it is claimed to be. Preserve original files, metadata, samples, product identifiers, packaging, transfers, access, working copies, test records, and the current location. A later photograph, replacement mat, exemplar product, laboratory result, or site visit should be labeled as such rather than substituted for the event-day item.

Build a feature-to-source matrix

  • Feature or item, event-day observation, measurement, image, diagram, product record, installation record, maintenance record, change record, and custodian
  • Standard or code proposed, edition, scoping basis, applicable provision, contrary information, and qualified reviewer
  • Question the material may help answer and questions it cannot answer by itself
  • Open conflict, missing record, access limit, alteration, repair, discarded item, exemplar, or test condition stated plainly

The applicable standard, condition, notice, causation, and legal responsibility depend on the property, surface, timing, evidence, and current law.
