Faster construction start – scan 2 bim
Construction projects rarely stop because of the construction itself, but more often it is unclear conditions. Many site adjustments and late decisions slow down the pace. When reality does not match the drawings, the result is often double planning, late adjustments and expensive construction errors. By using 3D laser scanning and converting point clouds to a BIM model at an early stage, a stable foundation for planning and coordination is created.
Surveying an existing environment with a stationary laser scanner or drone-based LiDAR generates a point cloud with very high precision. This makes it possible to build a model that not only reflects the actual design of the building, but also reveals deviations from old drawings and provides a clear picture of installation density, skews, openings and height levels. This eliminates uncertainties that usually only appear during production right at the survey stage.
One of the biggest technical advantages of Scan to BIM is that all parties working on the project have access to a common, digital model, already at an early stage. Coordination can thus work against actual measurements, rather than against any assumptions. This makes it possible to carry out early collision checks between, for example, load-bearing frames, ventilation ducts and electrical ducts. This in turn reduces the need for design reserves and reduces the number of iterations in the design phase. For the construction management, this means that the technical coordination meetings are more about how to focus on operation rather than troubleshooting.
When fitters work against a model that matches existing conditions, the need for site adaptations is also reduced. Installations can be pre-produced with greater certainty, which also shortens lead times in the production chain. It is also possible to continuously quality-assured the work by comparing what has been built with the point cloud from the scan. This way, you get an as-built verification that follows the project step by step.
In practice, this means that quantity takeover, component planning and logistics can be planned with greater accuracy. For managers who take over the building, it also means that the BIM model, if maintained correctly, can function as a digital tvilling.
Technology itself is no longer an obstacle. With modern equipment and well-thought-out scan planning, even larger objects can be scanned in a couple of days and converted into a model that is detailed enough to be used directly in design. The right level of LOD and clear structuring of the models make it possible to prioritize what is relevant to the needs of the particular project.
Scan to BIM is a technology that reduces uncertainty, reduces coordination errors, improves decision-making, and creates a common language between the field and the office. And it starts with you knowing exactly what it actually looks like.
