Evidence categories

PGMS / as-built data

Position and as-built data can support review of installed geometry and handover records.

Pipe position and alignment records

Installation records help connect the design intent, trench geometry and actual pipe position.

Foam application records

Foam application data supports review of the controlled installation sequence and installed support approach.

Installation QA/QC

Quality records can capture the checks, hold points and site observations relevant to the installation method.

Field validation

Field validation should be reviewed for relevance to pipe specification, ground conditions, access and installation sequence.

PACE outputs

Exportable PACE reporting can document the assumptions behind cost, programme, material movement and sustainability comparisons.

Project-specific review

Evidence supports decisions; it does not replace engineering judgement

PGMS and installation records support technical review and handover. They do not replace project-specific engineering, geotechnical, contractual or regulatory validation.

  • Review evidence against the actual trench geometry, access constraints and ground conditions.
  • Check foam design and application assumptions against the project-specific engineering context.
  • Use installation records to support handover, not as a substitute for method statements, temporary works or regulatory approval.
  • Use PACE exports to keep business-case assumptions traceable during technical and commercial review.

Request evidence for a specific context

Share the installation context, constraints and business-case question. HydroFoamer can help frame a scenario before detailed project work begins.
