CONSTRUCTION LASER SCANNING SERVICES

Yes. Scan to BIM is well suited to heritage, irregular and complex buildings because laser scanning captures geometry that is difficult to measure manually. The modelling approach should be carefully scoped because highly detailed or non-standard features can require additional modelling time.

The timeframe depends on the size of the site, access conditions, amount of scanning required, model complexity and level of detail. Site scanning may be relatively quick, but modelling time can vary significantly depending on the required deliverables.

Revit models are commonly provided, along with registered point cloud files and supporting documentation where required. Depending on the scope, we may also provide DWG, IFC, PDF drawings, elevations or sections.

Yes, a Scan to BIM model can support clash detection and coordination, especially when new design models need to be checked against existing conditions. The usefulness of the model for clash detection depends on the level of detail and which elements have been included.

The accuracy depends on the scan methodology, registration process, modelling scope and required level of detail. The model is created from measured scan data, but modelling tolerances and element simplification should be agreed as part of the project brief.

Yes. Scan to BIM is particularly useful for refurbishment, redevelopment, fitout and adaptive reuse projects because it gives the design team an accurate model of the existing building before new design work begins.

Yes, visible and accessible MEP services can be modelled where required, such as ductwork, pipework, cable trays, plant equipment and major service routes. Concealed services that are hidden behind walls, ceilings or floors cannot be accurately modelled from laser scan data alone unless verified through other information.

The level of detail depends on the project requirements. We can create simple massing or architectural base models, more detailed architectural and structural models, or models that include selected visible services and complex geometry. The modelling level should be agreed before work begins.

Existing drawings are helpful, but they are not always required. If drawings are available, they can assist with understanding the building and setting up the model. However, the laser scan and point cloud provide the measured record of current site conditions.

Yes. We can convert registered point cloud data into a Revit model at the agreed level of detail. The model can include architectural, structural and visible services elements depending on the project scope.

A point cloud is the raw or processed 3D measurement data captured from the laser scanner. It shows the geometry of the site as millions of points. A BIM model is a structured digital model made from building elements. The point cloud is the measured reference, while the BIM model is the usable design and coordination output.

Scan to BIM is the process of using 3D laser scanning to capture an existing building, then converting the scan data into a BIM model. The laser scan creates a point cloud of the physical environment, and the BIM modelling stage converts that data into usable model elements such as walls, floors, columns, roofs, openings and other agreed features.
