Full-environment as-built point cloud capture of process plants, offshore platforms, refineries, and large fabricated structures — producing a measurement-accurate 3D spatial reference that reflects what is actually built, not what was originally designed.
A digital twin is only as accurate
as the data it is built from. For complex industrial facilities — process
plants, offshore platforms, power stations, refineries, and large fabricated
structures — the gap between as-designed drawings and as-built reality is
rarely zero. After years of modification, repair, and incremental change, it
becomes substantial.
3D area scanning using terrestrial
laser scanning (TLS) and photogrammetric survey techniques captures the precise
as-built geometry of a facility — every pipe run, structural member, equipment
item, cable tray, and access route — in a navigable, measurement-accurate 3D
point cloud. This dataset becomes the single, definitive spatial reference for
your facility: accessible to engineering, inspection, operations, and
maintenance teams without requiring additional site visits.
Unlike CAD models built from
design drawings, a 3D area scan captures the facility as it exists.
Modifications made without drawing updates, equipment relocated during
commissioning, and minor deviations accumulated over years of operations are
all captured — making the point cloud the authoritative record of as-built
condition.
