Common questions about As-Built Engineering.

How does LiDAR-powered As-Built differ from traditional As-Built?

Traditional As-Built relies on field measurement + sketch + redraw, which introduces 5-15% dimensional error and takes 3-5x longer. LiDAR-powered As-Built starts from a survey-grade point cloud (1.9 mm @ 10 m), then drawings are extracted within Cyclone + AutoCAD / SmartPlant. Faster, more accurate, with permanent baseline preserved.

Which CAD platforms do you deliver in?

Native AutoCAD .dwg as primary deliverable. SmartPlant for refinery + petrochem workflows. MicroStation for legacy ENPC hand-overs. Custom format on request. All drawing sets structured for native Wistwin platform ingestion.

How long does a typical As-Built engagement take?

Single P&ID drawing: 1-2 days from registered point cloud. Plant-wide P&ID + Iso package: 8-16 weeks. Full plant documentation rebuild (P&ID + Iso + SLD + GA): 16-32 weeks. Joint scoping within 72 hours.

Do you bundle As-Built with LiDAR capture?

Yes. Most-common bundle. LiDAR + As-Built single-engagement pricing on request. Continuous CEng + CAD Lead oversight from field capture through drawing-set sign-off. Single Principal Reviewer signature.

How does As-Built handover to Wistwin work?

Drawing-set structured for native Wistwin platform ingestion. Tag-asset hierarchy mapped to digital twin object model. P&ID → process flow object. SLD → power distribution object. GA → spatial reference. Continuous synchronisation supported.
