- The technologies used for planning, design and construction have been developing considerably over the past decade. Since today's objects are very complex, it is necessary to provide a faster and more accurate way of recording the existing condition. GO2BIM uses the modern 3D laser scanning method to provide fast and high-quality collection and processing of a large amount of spatial data.
Laser scanning of biggest Thermal Power Plant in Croatia is an example of the high-quality application of this technology for the purpose of creating the project documentation of the existing condition. While working in the field, a modern Faro laser scanner was used for detailed scanning of Thermal Power Plant, with approximately 2500 scans recorded. Along with the data collected using the laser scanning method, 3600 photographs were recored with the application of photogrammetry, using a drone.
The laser scanner is of practical size and, together with an adjustable tripod, it is easy to move the scanner even on a complex object with many narrow passages and obstacles such as a thermal power plant. It is precisely because of its ability to use it in hard-to-reach and complex parts of a facility, the use of a laser scanner enables immeasurable speed and accuracy of spatial data collection in comparison to conventional manual measurements.
After completing the field work, collected data is processed in the office. Scans are processed and registered to obtain a whole and unique point cloud of the scanned area. The point cloud is then georeferenced, i.e., placed in the reference coordinate system of the Republic of Croatia - HTRS96/TM. A georeferenced point cloud is further used to create the final detailed 3D model that faithfully displays the existing condition of the Thermal Power Plant. The aerial images recorded with the drone are also processed to obtain a whole point cloud, placed in the HTRS96/TM system, which is used to make, i.e., display topography of the recorded area.
The final 3D model is a BIM (Building Information Modeling) model that contains a number of additional information such as type and quantity of built-in building material, details on embedded equipment, various system sets etc., and it also provides architecture, engineering and construction designers with insight and tools for more efficient planning, designing and building along with infrastructure and building management. It is important to emphasize the large amount of complex metal structures of the thermal power plant, which, thanks to the experience of our employees, is displayed faithfully and in detail in the BIM model. The level of detail used for Thermal Power Plant BIM model was LOD 300. In this way a high-quality model of high precision, size, shape, location and orientation was created.
3D laser scanning enables quick and efficient collection of accurate spatial data of large complex objects. By processing the collected data, a whole point cloud is placed in the official reference coordinate system and used to create a final BIM model that faithfully displays the existing condition. The application of the laser scanning method enables a faster, simpler, high-quality and more economical way of measuring, and the production of project documentation in comparison to traditional methods.
I wish there was a standalone project where I could walk around this plant. The amount of work put into this...
Amazing work. We also have a Faro Scanner, what did you use to register all the scan data ? Thanks
oh dear I`m impressed
Excellent!
What software did you use for modeling this kind of plant ?
I am trying to program a drone to do this with artificial intelligence for my senior project, is there any chance you could tell me what kind of hardware was used in this process, the department is shopping for drones and laser scanners
what was the purpose of the scan ? im still clueless
the fact that you are clueless about how to use such a model could mean that you do not have the background to understand the explanation. I don't know. But I think your question is perfectly reasonable. It begs the question, why wasn't it modeled in the first place, before any part of it was constructed? That is a complicated topic. The scan is always an after the fact function that should theoretically not be necessary. The main reason I think this is not very often the case is because its a matter of Control over who is in charge of the Construction. The Builder, or the Architect. That, and it may take longer to initially model the building and it's components properly than to simply document the AS-BUILT process as you go. This is a highly debatable topic as well. But it all boils down to a matter of who controls the construction of the building and how the Owners/Investors want to invest their funds. One way is not necessarily better than the other. And no two projects ever have the same factors that determine which way to go. Just because something is possible with a computer, does not mean it is always feasible. Technology is like a teeter-totter with Architects on one side and Builders on the other. Sometimes one side is up, and sometimes its the other. My observation is that the Point Could is being used with good leverage at this time to the advantage of the Builder. It keeps them from being so dependant on the Architects Plans and allows them to keep moving at the necessary pace in spite of the Plans. I know this is not going to be a popular point of view :)
@@sjepson100 mots of the time scans are used to picture something in a realistic way for the client with textures or hig definition , with this one , a 3D model was made, too , which make the scan a bit irrelevant dont you think ? even more with the fact that no textures are used with it , which is usually one of the main reasons why you do
photogrammetry.
Benjamin Mercier - No. Pretty pictures and graphics are not the important reason for point-cloud scanning. It’s what you can do with the **model** in terms of the construction process/coordination, analysis of the system functions, planning for future modifications, maintenance, facilities management, Energy evaluations, thermal and material stress, probably more things than you have ever imagined or you would not be thinking it’s for the sake if image files. Also, the reason to scan this facility is because it is a a very good example of the capabilities if the scanner. The data that can be extracted from the model can be used with HoloLens - also for more holographic functions that you may have ever thought possible. Such as training people how to operate and maintain the facility. Trust me. The scan is not just about making pictures.
The 3d model is one of the first steps to achieve industry 4.0. Take a look ua-cam.com/video/GuktZqtvces/v-deo.html
