Existing Conditions Documentation: What to Capture Before Design or Renovation

HomeBlogExisting Conditions Documentation: What to Capture Before Design or Renovation

Existing-conditions documentation is the foundation for renovation, retrofit, due diligence and facility planning. Missing context at the start of a project often becomes a return site visit later.

Start with the decisions the team needs to make

The right capture method depends on whether the team needs general visual context, dimensional verification, model creation, equipment documentation or a complete owner record. Avoid collecting data simply because a camera or scanner is available.

Use multiple capture types when the project requires them

  • Flat photos for targeted conditions and details
  • 360 imagery for broad visual context
  • Laser scans and point clouds for dense geometry
  • Floor plans and drawings for spatial reference
  • Video for walkthroughs or continuous routes
  • PDFs, reports and design files for project context

Connect the documentation to the floor or location

A usable record should answer more than “which folder is it in?” OcuMap organizes media around the building, floor, floor plan or feature it describes so remote teams can understand the spatial context.

Measure from the right source

When a supported photo is calibrated, OcuMap can measure lengths and areas from the image. LAS, LAZ and E57 point clouds can be measured natively. Survey and design requirements should still be based on authoritative sources appropriate to the required tolerance.

Keep the baseline for later comparison

Existing conditions become more valuable when they are not discarded after design. OcuMap can compare documentation from the same location across dates, turning the pre-project capture into a baseline for construction, operations and future renovation.

Deliver the record, not another download folder

A Published Viewer can provide a read-only project experience to the owner or consultant while preserving the internal organization and original files.

Practical checklist

  • Define the building, floor and floor-plan context before organizing files.
  • Capture both broad context and targeted details.
  • Use point clouds when dense 3D geometry is required.
  • Keep drawings and design references with field documentation.
  • Retain a pre-project baseline for later comparison.
  • Plan the owner handover before the project ends.

Common questions

Do I need both photos and a point cloud?

Not always. The right combination depends on the project. Photos provide context; point clouds provide dense 3D geometry.

Can OcuMap create the Revit model?

No. OcuMap can display supported design references; model authoring remains in tools such as Revit.

Can existing-condition documentation be delivered to the owner?

Yes. A Published Viewer can present selected records in a browser-based read-only experience.
