Survey-grade geometry for brownfield process plant · the layer every other twin layer stands on.
A digital twin is only as good as the geometry beneath it. We scan your operating plant, register the cloud to a monumented survey control network, classify it by asset category, and hand it over in the schema your platform ingests · with the accuracy achieved reported per registration rather than claimed.
Because the geometry is assumed to exist and it does not. The CAD model in the drawing office reflects the plant at handover, not the plant after fifteen years of tie-ins, re-rates and shutdown modifications. Hand measurement of an operating unit takes months, produces a sample rather than a survey, and cannot be re-verified once the scaffolding is down. Photogrammetry gives you a visually convincing model without survey-grade dimensional control, which is adequate for a walkthrough and inadequate for a clash check.
The consequence is predictable. The asset register, the condition-monitoring layer and the maintenance simulation all get built on geometry nobody has verified, and the first field discrepancy discredits the whole programme. A registered point cloud is the only foundation that is measurable, re-measurable and auditable · you can prove what the plant looked like on the day it was captured, and you can re-scan the same control network in three years and difference the two.
Chartered Engineer signed deliverables · scan-to-twin handover ready · routes to the 3D LiDAR practice lead within 24 hours.
Scan positions planned for line-of-sight coverage of congested pipe racks and equipment interiors. A permanent ground control network is established and monumented so a re-scan in year three registers to the same datum rather than to itself.
Tripod and trolley-mounted terrestrial scanners through process areas, with the capture sequence built around live operations, permit windows and hot-work boundaries. Typical brownfield throughput is 100,000 m² per day of accessible area.
Cloud-to-cloud registration constrained to the survey control network, not free-registered. Accuracy verified against independently measured check points and reported per registration, so the tolerance is evidenced rather than claimed.
Automated classification into piping, structural steel, equipment, cable tray and civil, followed by manual QC of the classes that drive downstream use. Coverage gap audit against the scan design before anything is released.
Delivered as E57, RCS, ReCap or IFC, or as a twin-native handover where the destination is our sister platform. Where it is another platform, the exchange schema and coordinate frame are documented so ingestion is a configuration task, not a translation project.
Deliverables reference the survey, exchange and information-management standards your audit teams and platform vendors cite. Every deliverable signed by a Chartered Engineer (CEng MIE India).
Three landmark engagements from our verified roster · quantified outcomes, no client names disclosed without written permission.
Captured during live operation across three permit windows. Registered to 1.8 mm against a monumented control network. Handed over twin-native, advancing the client's twin programme by five months against their internal survey plan.
Cleanroom and utility scan delivered with a documentation chain built for GMP review · instrument calibration records, operator qualification and per-registration accuracy reports issued as part of the deliverable rather than on request.
Scanned under hot-work-safe protocol during operations. The resulting model allowed maintenance planning to be done from the desk, reducing surveyed field exposure on subsequent shutdown preparation by around 60 percent.
