Existing buildings
Models of envelope, structure, partitions, levels, openings and whatever else matters for alteration or refurbishment.
Service · Scan to BIM
As-built drawings and BIM models of what is already built.
We scan the asset with LIDAR and, from the point cloud, produce as-built drawings (floor plans, sections and elevations) or an as-built BIM model in Revit and IFC — the workflow known as scan to BIM. It serves refurbishment, maintenance, extensions, facility management, technical coordination and the documentation of real assets. We work from our own capture in Spain and across Europe, or from a point cloud you already hold.
A BIM model that starts from built reality.
A BIM model is an intelligent digital mock-up of the building: not loose lines, but walls, slabs and pipes that "know" what they are and carry their dimensions and properties. "As built" means it reflects what was actually constructed — derived from the point cloud, not from old drawings — so you work against what really exists. We model to the level of detail each project needs, no more and no less.
MEP and industry
Services and equipment
Pipework, plant rooms, supports, equipment, service routes and clashes, modelled for coordination and maintenance.
Heritage
Singular geometry
BIM documentation of historic buildings and existing elements, with criteria adapted to conservation and management.
As-built drawings or a BIM model: which one you need.
Both deliverables come from the same point cloud, but they do different jobs. A measured survey is enough to take dimensions, design a refurbishment or apply for a permit; a BIM model pays off when the asset has to be coordinated across disciplines, maintained or managed for years.
2D
As-built drawings
- Floor plans, sections and elevations drawn over the point cloud, showing what was actually built.
- Dimensions and areas measured on the scan, not copied from old drawings.
- Suited to refurbishment design, permits, quantity take-off and existing-conditions documentation.
3D · BIM
As-built BIM model
- Elements that carry information: walls, slabs, openings, services and equipment.
- Delivered in Revit (RVT) and IFC, with the drawings generated from the model itself.
- Suited to coordination, clash detection, maintenance and asset management.
If you are not sure which one you need, we decide it with you when defining scope: that is the BIM consultancy step that comes before scanning. The model's level of detail is set using LOD levels. The point cloud is always delivered, in open formats (E57, LAS or LAZ); from it we produce whatever the project needs: 2D drawings, a BIM model, Gaussian Splatting or a 360 virtual tour.
Capture and modelling by the same team.
Search for "scan to BIM" in English and most results are drafting bureaux that model from a cloud someone else captured. That works, until the model and the cloud disagree and nobody owns the discrepancy.
We do the capture ourselves
- Our own field team scans the asset, so the accuracy of the cloud is our responsibility, not a supplier's.
- If something on site cannot be reached, that is recorded as an explicit assumption rather than quietly modelled.
- Site logistics, access permissions and coordinate systems are handled locally.
Or we model your cloud
- We accept E57, LAS, LAZ, RCP and PTS from any capture provider.
- We assess density and registration quality first, and tell you what can be modelled reliably from it.
- Where the cloud falls short for the intended LOD, we say so before quoting rather than after delivery.
LOD, uses and deliverables before modelling.
A good as-built model is not the heaviest one, it is the one that answers the technical decision. So we agree scope, families, tolerances and formats before production starts.
BIM deliverables
- Revit, IFC or other formats, to suit your workflow.
- Plans, sections and elevations derived from the model.
- Coordination with the point cloud and survey references.
- Organised by discipline, level or zone.
Modelling criteria
- Level of detail matched to the use: concept, construction, maintenance or inventory.
- A clear separation between modelled geometry and the reference point cloud.
- Control of existing elements, deformations and one-off details.
- Assumptions documented wherever areas were not accessible.
Capture base for as-built modelling.
The point cloud of the Santillana Canal conduits (Canal de Isabel II) is exactly the kind of starting data we model as-built from: real geometry of pipework and existing elements, with no reliance on old drawings.
From cloud to model.
We combine capture, registration, technical reading and modelling so the result is usable on site, in the design office or in asset management.
01
Scope and LOD
We agree model uses, disciplines, level of detail and delivery formats with your team.
02
LIDAR capture
3D survey of the asset at the accuracy and coverage modelling requires.
03
Cloud registration
We merge and clean the point cloud that will act as the faithful base for modelling.
04
As-built modelling
The model is built on the cloud, separating disciplines and priorities of use.
05
Review and delivery
Consistency checks, export to RVT / IFC and handover of the associated documentation.
What each LOD means in practice.
LOD (Level of Development) describes how much geometric and data content each model element carries. More LOD is not "better": it is more expensive and slower to produce, so we set it against the decision the model has to support.
LOD 200–300 · Volume and geometry
- Elements represented with approximate or exact shape and dimensions (walls, slabs, openings).
- Enough for concept design, area measurement and basic coordination between disciplines.
- The usual level for residential and commercial refurbishment.
LOD 350–400 · Coordination and services
- Includes connections between systems, supports, pipes, trays and equipment at real dimensions.
- Needed where clashes have to be found before works, or MEP coordinated with structure.
- The level we normally work at in industry and water infrastructure.
The model is built on the cloud: the scanning process shows how each stage fits before modelling starts. Fixing the LOD before scanning avoids two common mistakes — over-modelling (unnecessary cost and programme) and under-modelling (a model that cannot answer the question that prompted it). That is why the first step of our process is always scope, not capture.
Questions about scan to BIM.
What are as-built drawings?
As-built drawings are the floor plans, sections and elevations of a building or facility as it actually stands today. We draw them over the point cloud from the laser scan, so every dimension comes from the real geometry rather than from design drawings that may no longer match what was built.
What is the difference between scan to BIM and a measured building survey?
Both start from a laser scan. A measured survey delivers 2D drawings (floor plans, sections and elevations); scan to BIM delivers a 3D model whose elements carry information, in Revit and IFC, from which those same drawings can also be produced. For a one-off refurbishment the drawings are usually enough; to coordinate, maintain or manage the asset, the model pays off.
What is an as-built BIM model?
An as-built BIM model represents the built reality of an existing asset, derived from its point cloud rather than from out-of-date drawings. It is the basis for alteration, refurbishment, maintenance and technical coordination.
Do you also capture, or only model from a cloud we supply?
Both. Unlike offshore BIM drafting bureaux, we carry out the capture ourselves, in Spain and across Europe, so the same team is answerable for the accuracy of the cloud and of the model. If you already hold a point cloud, we can model from it — and we will tell you up front what its density and registration quality allow us to model reliably.
How does a point cloud become an as-built BIM model?
In five stages: agree scope and LOD, capture the cloud with a LIDAR scanner, register and clean it, model the elements (walls, slabs, services) on the real captured geometry, then review and export to Revit or IFC. The result is intelligent BIM elements that reflect what was actually built, not out-of-date drawings.
Which formats is the model delivered in?
We deliver in Revit (RVT), IFC and other formats to suit your workflow, with derived plans, sections and elevations, and coordination against the reference point cloud.
What level of detail (LOD) do I need?
The right LOD depends on the use: concept design, construction, maintenance or asset inventory. We agree scope, families, tolerances and formats before modelling, so the model answers the technical decision rather than chasing file size.
