Point Cloud to BIM Conversion – A Reality Check

Point Cloud scan to BIM is a 3D model created with laser scanning. Point cloud modeling is widely popular for its precision. As you can extract detailed elements of an object captured in physical space.  This enables accurate modeling,  clash coordination and quantity takeoff (QTO) or Bill of materials (BOQ). Several construction projects in the renovation and the extension stages are using point cloud scan to BIM process for 3d model creation, 3d visualization, animation and quality inspection. Scan to BIM modeling involves the technique of making a digital representation of an existing building condition with its functional and physical attributes. Laser scanners facilitate in obtaining a perfect 3d scan to BIM, which is then imported into the 3D BIM software. Faro scan to BIM process is designed by architects, engineers and general contractors to process 3D laser scan data quickly and accurately. Revit scan to bim is also popular for creating as-built models for refurbishment and renovation.  Scan to BIM revit facilitates creation of as-built BIM model for renovation work of infrastructure asset including tunnels and bridges. In the AEC sector, laser scan to bim best practices are used by the surveyors, owners, architects, engineers and general contractors for their renovation and refurbishment projects.

What are the laser scan to BIM services?

  • 3d Modeling – 3d models are created from laser scan to BIM process for architectural, structural and MEPFP services for the sake of renovation and extension work. The process of scan to BIM modeling enhances transparency, streamlining communication for quick decision making throughout the project lifecycle. High quality revit scan to bim modeling ensures that the Revit components are built intelligently with the practicality of serving the purpose. Parametric Revit families contain a realistic information about performance models, required for executing calculation analysis and construction simulation.

Future for 3d Laser Scanning Services in Construction

3D laser scanning services near me

Laser scanning services talked much about, adopted for convivence but is not new to the Construction Industry. Its journey started in 1960’s with camera, projector and lights. Even though the benefits of first laser scanning equipment were adopted yet it was time consuming. Infact present day 3D Laser scanning and modeling services are popular land surveying method. It is supporting BIM Services for accuracy in Construction for Architectural and Engineering industries. But how does 3D scanning services being non-destructive works more accurately.

In comparison to the old scanning equipment’s the present ones are technically more advanced. Loaded with photodetectors, Global positioning system (GPS),  advanced sensors. The modern laser scanners uses laser beams along with other scanning components  to calculate accurate coordinates of structures.

How Does Laser Scanning Works:

Light from a scanning system is bounced off onto the surface and reflected back to the sensors. Now, the sensors calculate the time taken by light  to complete its journey. This time measurement known as “time of flight” helps us to calculate how far the surface is located. The measured distance hit by laser beam is  used to calculate coordinate for a small section of the surface. With seconds of single scan, millions of 3D coordinates are collected by laser scanner.  3D coordinates are in form of point cloud data. Then point cloud processing software transforms the detailed point cloud data into 3D model.

Conversion of Point cloud scan to BIM generates digital representation of scanned surfaces reflects:

  • Dimensions of scanned surface
  • Spatial relationship of topographic features and structures.

Various Scanning Techniques:

 

  • LiDAR or ALS –

    In 1985 simple scanners were replaced by LiDAR system. LiDAR Light Detection and Ranging is popularly known as air-borne laser scanning (ALS). This remote sensing technology facilitates map assisting, monitoring and assessment of forest resources. Laser device in LiDAR emit beam of light and measure the time of delay between emitting and reflection to calculate depth of the structure. LiDAR survey in construction create digital twin for BIM applications. The point cloud data gathered facilitates 3D model  of the object and generate geospatial information.

The basic difference between LiDAR and Laser scanning techniques :

  • LiDAR scans a particular area whereas Laser scan scans

     Application of LiDAR in Construction:

LiDAR laser scanning is being applied from construction to automobile, space and even for environment. LiDAR data is used to monitor

  • Surveying:   LiDAR map create digital terrain and digital elevation models used by surveying with collected three dimensional coordinates.
  • Architecture:  Laser scanning system surveys in-built area as well as roadways, railways, covered building.
  • Real-Estate: Scanning equipment’s measure accurate floor plans for architect and structural engineers.
  • Construction: The LiDAR survey produces digital twin for BIM application. Not only the technology tracks building projects . But also, monitor structure, revit models Through laser scanner 3D coordinates are gathered in form of point cloud data. The point cloud processing software transforms the detailed point cloud data collected by laser scanners into 3D model.

 

 

  • SLAM or Simultaneous Localization & Mapping –

    SLAM map is an algorithmic process to navigate environment with robot or unmanned vehicles. SLAM scanning process are adopted for very small or dangerous area through remote GIS data collection. SLAM scanners establish a wide array of sensor types such as audio rangefinders, visual cameras and inertial sensors. Nevertheless, LiDAR and laser scanners are crucial for producing accurate SLAM scans, and are used for BIM planning. Reality capture and digital transformation is driving automated construction workflow with SLAM and BIM (Building Information Management) collaboration. Giving platform for SLAM-to-BIM which is a subcategory of Scan-to-BIM. As all BIM is not same. BIM Level3 delivers improved construction workflow with maximized ROI whereas BIM Level 2 is adopted by UK which concentrates on CAD.

Scan to BIM uses 3D laser scanners to build BIM schematics for multiple spaces. This can be done at multiple stages : pre-construction, during construction or post construction.

  • Prior to Modeling: Scanners capture detailed site data for BIM planning before modeling. This stage is preferred for renovation or any project considering the environmental outcome also.
  • During Construction: A quality controlling step. It can be implemented to different stages for detecting any anomalies or errors. Scanning prefabricated parts before dispatch.
  • After Construction: Scanners capture additional site details to be included in BIM schematic. This not only improves site management but could be supportive in facility management during construction life cycle.

 

         Difference between SLAM-to-BIM or SCAN-to-BIM:

Spatial information with SLAM are used as a source for BIM planning. The outcomes with SLAM-to-BIM and Scan-to-BIM are same the only difference is that the latter uses either LiDAR                 or any there scanning technique for facilitating results.

Benefits of 3D Laser Scanning Services in Construction:

  1. Faster Collection of Data:

 

  • Drones –

    Currently, drones are gaining significance in point cloud scan to bim. These unmanned aerial systems  are often used  with SLAM scanners, together with conventional LiDAR and GPS improved LiDAR. Mapping and surveying through drones deliver an easy-to-deploy podium for capturing aerial views. At present, some factors are restricting the use of drones about the time of operation and the development of regulations in several countries.  Drones help to produce valuable 3d laser scan to BIM process, which is essential for various engineering projects and undertaking scientific tasks
