Interior record

Interactive walkthrough

The interior tour preserves room layout, access, and annotated locations for later review.

Overview

Project overview

The purpose of this work was to preserve interior and exterior conditions as a reviewable spatial record. Interior capture documents room relationships and close-range conditions. Exterior photogrammetry documents the building envelope, access, and surrounding context.

Demonstration project illustrating an interior/exterior documentation workflow. Sampling labels or laboratory values shown in the models are fictional and included only to show how location context can be referenced inside a record.

Objective

What needed to be preserved

The record was scoped to conditions that later professional review would need after the site has changed.

  • Interior layout and room relationships
  • Corridors, access, and transitions
  • Exterior envelope and site context
  • Visible conditions at the time of capture
  • Location context for later sampling or review notes

Methods

Capture methods

  • Matterport / terrestrial capture. Interior scanning used to create a navigable walkthrough of rooms, corridors, and annotated locations.
  • Exterior photogrammetry. Overlapping stills processed into an exterior 3D model of roof geometry, elevations, and access.
  • High-resolution imagery. Still photography used for close visual reference and annotation.

Deliverables

What was delivered

  • Interior walkthrough
  • Exterior 3D model
  • Annotated views
  • Spatial context connecting interior rooms to exterior conditions

Deliverables were selected for this documentation objective. Not every forensic engagement includes the same set of products.

Combined capture

Why interior and exterior records were paired

Interior capture provides room-level continuity. Exterior mapping provides broader site context that a walkthrough alone cannot reconstruct.

Exterior model

Exterior 3D documentation

The exterior model preserves roof planes, elevation transitions, and site access for later comparison with interior conditions.

Interior capture

Terrestrial scanning in the field

Interior capture was planned around line of sight, scan spacing, and room continuity so corridors and transitions would stitch into a navigable record. Matterport is the capture tool used for the walkthrough; the product is the interior documentation, not the scanner.

Terrestrial scanner in place during interior documentation

SterFlies documents field conditions. Mold assessment, industrial hygiene interpretation, and health-related conclusions remain with qualified professionals.

Technical considerations

The walkthrough preserves navigable interior continuity, and the exterior model preserves envelope and access context. Neither establishes moisture source, mold extent, or a health conclusion. Sampling labels in this demonstration are fictional and show how a location can be referenced. The record is not an industrial hygiene assessment.
