Point cloud to BIM and its key advantages


Point cloud to BIM is the process that utilizes 3D Laser scanning technology in order to display the as-built environment. This technology has been praised by industry experts and tagged as the gold standard for all 3D-rated models. This 3D laser scanning creates a point cloud map of any building or structure which can be used for generating extremely detailed and accurate 3D models. The cloud is formed by multiple scanned objects represented by points and the higher the number of points, the higher the chance of accuracy. In this, article we will have an overview of Point Cloud to BIM as to why is it used, how and where it can be applied, its benefits, etc.

Significance of Point cloud to BIM and their Applications:

Scan to BIM as a process has a huge scope of applications and numerous disciplines where it can be beneficial. Scan to BIM facilitates retrofit, renovation, and refurbishment projects by generating as-build models. It also enhances the process of creating intelligent BIM models by providing accurate point cloud data. One of the key applications is its utilization for comparing original plans to their as-is state. Alongside it also strengthens construction safety management by identifying construction threats and providing measures to tackle the same. By utilizing 3D laser scanning technology virtual installation and assembly of components become possible, which in turn helps in identifying if there are any clashes before actual installation starts. It augments the facility management of a building by providing documentation such as shop drawings, as-built drawings, MEP and architectural drawings, etc. As Built Drawing Services can be utilized in order to get accurate information about existing structures or buildings which do not have proper documentation of design or functionality. Thereby providing documents for further modifications.

Key Advantages of using Point Cloud to BIM:

1. Accuracy: 

The design derived by using point cloud to BIM is reliable, as it is detail oriented, specific, and precise. If the collection of data is accurate, the results are definitely going to be good. The 3D laser scans enable the visibility of the most ingrained elements of the structure, for e.g. beams of a building, thereby improving accuracy tenfold as compared to manual surveying. Traditional surveying was not reliable as it was largely dependent on the surveyor and his knowledge, mindset, and skills while considering multiple other factors. Along with this, manual surveying does not always allow for accurate surveys as it is not always possible to get to certain parts of the building which are entrenched and difficult to access, and even more complicated to measure. However, Scan to BIM allows you to create a highly accurate three-dimensional digital representation of your building which has proven to be an easier way out with increased efficiency and accuracy in a relatively faster time duration.

2. Time efficient: 

Point Cloud to BIM Services provides the most intricate details of the structure through a digital setting, it eliminates the need for frequent visits to the site, thereby increasing time availability to the contractor to initiate the planning process, evaluate the project risk and provide them time to focus on other finer aspects of the project. The time taken by the technology to provide the details about a structure is considerably fast as compared to the turn-around time taken by the technicians deployed to perform the same function.

3. Cost Efficient: 

Sourcing of 3D models is undoubtedly not cheap, howsoever when we compare it with the traditional 2D survey, it results in great savings. This is because traditional manual surveying methods are significantly costly and require multiple technicians to execute the same, on the other hand when we perform the function through a laser scanner it is a one-time investment that provides improved precision and detailed scans which can be further utilized to develop 3D BIM models which are coordinated and error-free and provide for efficient project execution. Owing to this errors can be detected at the earlier stage of project lifecycle which considerably brings down the cost of rework or saves the cost of mistakes, as the result achieved by using the technology is reliable and proficient.

4. Enhances Collaboration:

Scan to BIM fosters transparency, better communication, and collaboration by allowing to share of relevant and accurate information on a cloud platform that can be accessed by all stakeholders. The 3D models that are developed from scans can help actively in understanding the existing underlying design and also aid in the process of discussing new or potential designs. This also makes it easier to understand and identify the design flaws, the technical updation required, etc., and thus helps the BIM engineers to coordinate and integrate the architectural, structural, and MEP models which are developed from the scan.
