Virtual Design and Construction (VDC) is our name for the combination of Building Information Modelling (BIM) and other advanced computer aided design techniques.


This includes 3D modelling, parametric design and analysis. By using VDC LJ Carroll Consulting adds value at all stages of a building’s life cycle.

We provide the following VDC services:

  • Parametric modelling. Parametric design can rationalise complex geometries and relationships – realising architectural aspirations that would not otherwise be possible.
  • Finite element analysis;
  • Non-linear analysis;
  • Thermal modelling and heat transfer analysis;
  • Full BIM implementation, including Revit and Tekla Structures;
  • Steel fabrication and precast concrete shop drawings produced directly from our structural models;
  • AR/VR visualisations;
  • 3D modelling to fabrication, i.e. 3D printing.
  • BIM Coordination services. Clash detection resolves design issues before the building is constructed – minimising the risk of costly design revisions during the actual construction phase.
  • Point cloud 3D scanning of existing structures including scanning from drones.
