Point Cloud to BIM is a process of using a laser scanner to capture high-density point clouds of a physical building, site or a structure. These HD point clouds are then converted to BIM Model to enable architects, engineers and general contractors model the renovation project with best success.
When the original construction documentation is not available or they are inaccurate, laser scanning can be used to gain an exact understanding of the building’s as-is condition. Point cloud data can be used to create information rich BIM models which are high in accuracy and which provide the precise information that could facilitate informed decision making throughout the reconstruction project.
What are the common challenges faced during renovation process?
Renovation, refurbishment or restoration of any building is different from new constructions and they are prone to unique challenges. One challenge could be that the current functioning of the building or roads should remain as it is and the reconstruction goes on simultaneously. When it comes to historic buildings another challenge is to ensure that the original design and the uniqueness of the building is maintained. Finally, it is also important to know which areas of the structure or the building can be conserved, what materials can be reused and what needs to be changed. All these challenges can be sufficiently addressed by Scan to BIM Services.
Advantages of Point Cloud to BIM for renovation projects:
1. Better Visualization:
3D laser scanning provides accurate information about the site or structure which can be used to create Revit models which allows for more reliability & quality assurance. 3D visualization helps the architects and engineers check how the completed design will look. BIM models can be used to create with virtual reality and augmented reality environments as well as 3D renderings to provide photorealistic views of the final design. Proper visualization of the final design is important when it comes to preserving certain historical buildings or ensuring certain elements of the building designs like intricate detailing, ornamental modeling, curves & grooves, don’t drastically change in appearance.
2. Accurate costing from project onset:
The data-rich BIM model has in-depth information right from the color of the model to the manufacture’s details, asset numbers to material properties and quantities. By gaining an exact approximation of the exact quantities it is possible right from the start of the project to calculate the cost. Any changes in the design and material quantities would automatically reflect in the price. By knowing exact costing, it helps the owners know what changes to make in order to ensure that the cost remains under control.
3. Enhanced Collaboration:
The building information model allows the stakeholders and BIM teams to work in collaboration with each other. Revit provides various tools like Revit Server which facilitates a cloud based environment where teams can work together not just across LAN but also WAN. It also has the ability to collaborate with multiple Revit users to work on a singular model. BIM Services, specifically Revit BIM also provides access to BIM 360, which connects project teams to real time data and constantly keeps them updated with each other.
4. It increases safety:
One of the biggest advantages of using point cloud data and creating BIM models is that it allows to detect clashes in the preconstruction stage itself and reduces onsite errors. It not just reduces rework and prevents waste of resources and cost but it also increases safety of both onsite construction workers and the inhabitants during any stage of the building’s lifecycle. BIM also helps understand any challenges which could potentially occur allowing the workers to gain a better understand of how to deal with it rather than being surprised by it onsite.
Thus, Scan to BIM gives the AEC industry a variety of advantages when it comes to restoration and reconstruction of existing buildings and structures. Its precise cost estimation, tools for structured workflow and speedy turnover time has together made it ideal for the construction industry.
