Digital Twins

A precise digital version of your site with metrics, condition and asset data.

How We Can Help
 

We create accurate, navigable digital twins of buildings and sites for planning, refurbishment and ongoing asset management. Using drone photogrammetry, indoor 3D laser scanning and RTK control, we capture complete as built data without disruption. Heritage estates, campuses and live facilities benefit from a single source of truth that everyone can trust.

Why This Approach Works

 

Traditional surveys are fragmented. Plans, photos and notes live in different places and are quickly out of date. A digital twin combines geometry, imagery and asset records in one environment. Design, FM and project teams collaborate against the same verified model, reducing clashes, rework and site time.

Cut Time, Cut Costs, See More

 

Fast capture by air and on site replaces scaffolding, shutdowns and repeat visits. You get a measurable model with visual context, so decisions are made from facts not assumptions. Share a secure viewer link and keep stakeholders aligned without travel.

​

Deliverables

​

  • Registered point clouds in E57, LAS or RCP

  • Textured meshes and photoreal 3D site models

  • 2D plans, elevations and sections in CAD ready formats

  • Scan to BIM models in Revit or IFC with agreed LOD

  • Orthomosaic maps and terrain models for external areas

  • Asset tags, room data sheets and basic condition attributes

  • Change tracking between survey dates for progress or defects

  • Hosted web viewer and secure file delivery

  • Survey control report, QA notes and metadata

 

Where This Works Best

​

  • Heritage sites and listed buildings

  • Hospitals, universities and large estates

  • Office, retail and residential blocks

  • Industrial plants and utilities

  • Pre refurb records and post works verification

  • Insurance, compliance and dispute evidence

 

Methods We Use

​

  • Drone photogrammetry for exteriors, roofs and grounds

  • Indoor 3D laser scanning for accurate interiors

  • Mobile SLAM LiDAR for corridors and complex plant

  • RTK survey control for reliable coordinates and alignment

 

Safety and Compliance

​

All capture is planned with task specific RAMS and CAA compliant procedures. We agree access routes, privacy zones and data handling upfront. Work is scheduled to minimise impact on live operations and sensitive heritage fabric.
