Presently, the construction industry is leveraging point cloud to BIM modeling to a great extent, thus developing 3D models of existing buildings. Point cloud modeling is also known as as-built modeling or scan to BIM modeling. The point cloud modeling process is becoming a sought-after technology, particularly for the building retrofit and renovation sector everywhere in the world.  Accordingly, top-rated BIM firms offer point cloud services through which they create precisely rendered 3D models of the structure by leveraging scanned information. This technology is leveraged by engineers, owners, architects, general contractors and surveyors to facilitate projects.

Using point cloud services is what allows BIM businesses to develop replica 3D models of several types of already built buildings. The 3D models are vital while carrying out the revamp of renovation of these existing structures. Point cloud modeling is possibly the most reliable way to work on building projects and get a complete view of existing structures. On the other hand, the major challenge is ensuring accurate geometric dimensions and specifications. Certainly, the adaptation process of the point cloud scanned data into a 3D BIM model is an elaborate one.

Let’s look at some of the points that should be considered while working on the different types of projects that need point cloud modeling. 

Adhering to the right process                                                                              

The foundation of any point cloud to BIM procedure is the images extracted from 3D laser scanning technology.  Consequently while carrying out the laser scan to BIM modeling process it is pivotal to ascertain that the scans are taken from accurate angles and recorded correctly.  Cumulatively this ensures that accurate scanned data is delivered to the point cloud services provider allowing them to render perfect 3D models of the existing structure.  A quality analysis and quality control checklist of 3D models would need to be followed. 

Utilizing relevant software

Apart from using the proper processes, it is vital that the relevant software is leveraged. Your provider needs to use solutions that read and accommodate data from laser scans as well as all types of point cloud files. For this purpose, integrated software plugins can be used for scanned data conversion into the appropriate format required to use the data without anything getting lost. 

Utilizing skilled professionals

Seeing as the point cloud process cannot be completely automated, it would require the services of experienced human technicians to analyze the scanned data. As a result, experienced technicians are a highly sought-after resource of any BIM companies particularly those that offer point cloud services. It is vital for these technicians to have highly honed skills and the capacity to create flawless designs.

As point cloud modeling can offer complete precision, it has been used by several companies to carry out construction projects where renovation and repairs are called for. Thus companies working on remodeling or refurbishing existing structures need to opt for point cloud services, precast concrete modeling, structural 3D modeling services and more.
