As-Built Surveys
Verification of installed works with accurate measurement, CAD deliverables, schedules and photo QA for client sign-off and handover.
What are As-Built Surveys?
As-built surveys confirm that constructed works match design intent. Triple Survey captures positions, levels and dimensions of installed elements, compares them to approved drawings and produces CAD deliverables and QA packs for handover.
Why they matter
Accurate records reduce disputes, support valuations and provide essential information for future maintenance and modifications. They demonstrate compliance with tolerances and specifications.
How we deliver
Using Leica TS16/GS18t we measure as-built geometry. Our office engineers validate in AutoCAD, issuing as-built drawings, mark-ups, schedules and photographic evidence. We can provide staged as-builts throughout construction.
What we capture
Foundations, slabs, steelwork, walls, façades, drainage, external works, and MEP fixed positions — to project-appropriate tolerances.
What we deliver
- Installed works verification vs design
- Dimensional checks and tolerance reports
- CAD as-built drawings, mark-ups and schedules
- Photo QA and auditable records
FAQs
They provide a definitive record of what was installed, reduce disputes, support valuations and assist future maintenance and alterations.

Yes — DWG/DXF with clear layers and annotation, plus PDFs and schedules as required.
Often same- or next-day depending on scope, access and review cycles.
Yes — we can verify critical hold points and produce progressive records.
Leica TS16 total station, Leica GS18t GNSS and digital levels with robust control.
Yes — photography and mark-ups can be included to evidence compliance and locations.
We can annotate variances and provide schedules showing differences vs tolerances.
Approved drawings/models, coordinate system, benchmarks, tolerance requirements and access plan.
Yes — we provide DWGs and references that can be consumed by common BIM tools.
