3D data transforms the complete building lifecycle with Scan to BIM or 3D Scanning Services


The AEC industry has become well-versed with the terms Scan-To-BIM, 3D Scanning Services or Point Cloud Modeling.  If there’s structure that needs to be scanned for rework or captured before demolition, it can be done with Point Cloud Services. The adoption of advanced surveying techniques like Point Cloud Scanning Services or photogrammetry have transformed the way the AEC industry needs to visualize construction projects for design and deliverables. The entire process can be integrated with BIM technology to create precise information-rich models that can be shared with the entire team.




2019 will look at Point Clouds or Scan-to-BIM in various phases of the building lifecycle
Reality capture will go beyond 3D models and BIM, it can be absolutely leveraged in the AEC industry to determine accurate scheduling, costing, and maintenance protocols of a project lifecycle. There has been an increased focus on reality capture technology and solutions with Point Cloud Modeling. There are multiple enterprises that use technology or scanners like Faro Focus, Trimble, Geo Slam Zeb Revo, Paracosm, and more to determine spatial analysis, lend clear visualization, greater accuracy, quantity estimation, and reduced faults.
How do you define Scan-to-BIM?
Scan to BIM or Point Cloud Services are referred to as scanning a physical space or infrastructure in 3D space. This builds a precise representation of the structure with a Point Cloud with BIM software. This software representation is leveraged to design, assess, and evaluate project progress and success.
Scan to BIM is Quick  
Point Cloud Scanning Services are a modern breakthrough in the AEC industry as it captures every minute dimension of the structure and delivers a faster, yet highly detailed representation of the actual structure for restoration or retro-fitting existing structures.
Point cloud data is extremely useful for project analysis as it is done through various processes. Multiple scans are taken various angles and stations, whilst secondly, each point cloud data is combined for post-processing requirements, and in the third step, a BIM authoring software is used to create information-rich models, also known as Point Cloud Modeling.

Scan to BIM is backed by modern technology

Point Cloud Scanning Services are useful for new projects as well, as it helps stakeholders create and maintain important records of the building or other structures around the new project. When it comes to time savings for complex projects, Scan to BIM technology can be record large interior and exterior spaces, or even electrical and plumbing installations, etc.
Surveyors are increasingly turning to the above-mentioned 3D scanning services or instruments that capture extremely detailed visuals and convert them into a point cloud. The magnitude of scanning in terms of area per day could be around 90,000sq.ft. to 120,000 sq. ft. depending on the complexity of the project(s). This technology is very helpful for buildings that are still in use, as terrestrial or mobile scanners can be used to cover or scan hard-reaching spaces or map true distances, and create an accurate master data-set of the project at hand.

How does it all happen?     
When all the Point Cloud Scanning Services or activities are done, and all the point clouds are linked together, they are taken into software like Autodesk Revit or any other algorithm -based authoring tools that identify each point cloud and transform them into 3D objects. This helps designers and modelers with detailed information for floor plans, elevations, and even complex building sections.
The scan to BIM process can begin at any point of the building lifecycle, and it has proved to be extremely helpful to renovate older structures with enhanced precision and information transparency through Building Information Modeling.

Benefits of Point Cloud Scanning Services
The AEC industry operates at strict budget timelines; thus, it requires great accuracy and transparency for contractors as it reduces the risk factor in terms of time and budget, whilst it increases the probability for bidders to win the bid for a certain project(s). Scan to BIM is extremely compelling for long-term project savings through exhaustive collaboration and intelligent, information-rich 3D models.

Final thoughts on Point Cloud Scanning Services
By using 3D Scanning Services coupled with BIM technology, the entire information flow becomes seamless for all the stakeholders. It creates a great impact on every trade; be it onsite or office. Scan to BIM is transforming the way AEC professionals or contractors connect all the dots.

The Benefit of Point Cloud Modeling Technology in the Generation and Computation of FEM Models

What is Point Cloud Modeling?

 

A set of data points in the space forms a point cloud. A 3D laser scanner produces these point clouds. It furthermore calibrates the number of points on the exterior of an object to be modeled. Then the final outcome of the Laser Scanning procedure is point clouds. As a matter of fact, some processes like 3D CAD modeling for fabricated components, MQC (Metrology & Quality Control) analysis, animations, etc., make use of these point clouds. The further procedure after this is point cloud modeling.




The post process of laser scanning consists of a Point Cloud Modeling software that renders the point clouds in the form of a 3D model. This conversion or rendering of point clouds to a 3D model is correspondingly known as surface reconstruction.

 

Applicability of Point Cloud Modeling

 

The uses of point cloud modeling are as below:
  • Photogrammetry
  • Mobile mapping
  • Geologic interpretation
  • LiDAR (Light Detection & Ranging)
  • Predictive modeling
  • Forensic analysis
  • Reverse engineering

 

Point Cloud Modeling. How it’s done?

 

Point cloud modeling is nothing but a ‘Scan to BIM’ procedure.
Point cloud modeling contains of a collection of 1,000,000 data points representing the three-dimensional coordinates of the exterior of a building or any other object. A 3D laser scanner then gathers or captures this data set known as point cloud.
With the help of surface reconstruction strategies and point cloud process computer code tools, the scanned data is furthermore reconstructed into an operating 3D BIM model that reflects the present condition of the building or structure.

Benefits of Point Cloud Modeling

  • A quick survey methodology
  • Precise 3D model creation
  • Reliable and assured modeling quality
  • Reduced site revisions
  • Reduced RFIs and work stalling
  • Detailed understanding of design models
  • Effective decision making
  • Cheaper project turn-around

 

Point Cloud Modeling Software

Not to mention, any process is incomplete without the use of a specific equipment or a system. Point cloud modeling hence makes use of software mentioned below:

1. Regard 3D

Regard 3D makes use of a series of photographs of an object for creating its 3D model. Different viewpoint help to capture these photographs.

2. 3DF Zephyr

3DF Zephyr is a software for commercial photogrammetry as well as 3D modeling, developed by an Italian organization; 3DFLOW.

3. Bentley ContextCapture

With ContextCapture, you can produce the most important and complex 3D models of existing real-world conditions, as well as scales as massive as entire cities, from straightforward images.

4. Reality Capture


Reality Capture is a photogrammetry software for creating 3D models from an diverse photographs taken from a camera or a 3D laser scanner of any object.

5. LiMapper

Green Valley International developed LiMapper for utilization in image processing and hence for photogrammetric surveys. The software has an ability to handle large data sets and moreover is a unique set of solutions for photogrammetrists.
The above mentioned point cloud modeling software are Windows, Mac OS, as well as Linux compatible. The users of these software can not only can offer a context for design, construction, but also have multiple operational choices for every type of infrastructure projects throughout the globe.

Final thoughts

 

On present day, the employment of point cloud services is quickly enhancing across the construction industry. Its implementation leads to getting as-built drawing of any residential building, historical infrastructure or building renovation. Lasers moreover facilitate tracing the flaws within a building. Thus, it helps in saving time and price spent on a general project. Therefore, 3D laser scanning and point cloud modeling are now becoming the support systems of BIM services.
