Building Information Modeling, which in short we call as BIM, is a 3D model based process that gives the understanding and the tools and techniques to efficiently design, manage, construct an infrastructure and buildings.
Professionals of architecture, engineering, and construction (AEC) use the Bim model for 3D visualization of any structure. We can find Bim services all over the world where lots of different clients are available to provide all the details and the techniques and tools used in the way of Bim.
What is the use of Bim?
The use of Bim is there to document and design any structure and building. Each and every detail of the building of any location is placed and modeled in Bim.
We will ask the question, what is the use of this model? The answer is very realistic that the use of the BIM model is for analysis to create visualizations and explore design options that may help all the workers involved in it get the in-depth understanding of the look of a particular building or a structure.
The model is also used for the purpose of generating the design documentation for constructing and building a particular structure. There is a presence of clients of Bim in India, and those who are in the need of the services of Bim may know about Bim clients to understand the complete technicalities of it.
What process gets involved in BIM?
We will get the answers to all such questions like how can Bim process support the creation of intelligent data? What is the use of such data in beam process in the lifecycle of any structure or building project? The answers to all such questions lie only in the process of Bim that not only supports the creation of intelligent data, but it can give a transparent platform for a building or infrastructure project also.
The best thing about Bim services is that it can be used throughout an infrastructure or a building project lifecycle. Let’s understand the processes that get involved in Bim in four steps mentioned as follows:
It becomes vital to inform project planning by combining real-world data and reality capture to get the contextual models of the existing natural and built environment. This first step in Bim process will be the most fundamental to proceed for the next step.
In this step, there's going to be a conceptual design and overall analysis along with detailing and documentation. For the sake of informing scheduling and logistics, there is going to be the use of reconstruction process, which will begin using the data of Bim.
In this particular phase, Bim specifications will be used. Contractors and other people involved in this process will get project construction logistics to make sure that there is going to be efficiency and optimum timing for building.
When there is a presence of finished asset, Bim data gets over to maintenance and operations of that finished asset. When there is any cost effective renovation or any efficient deconstruction, there too, there is a great use of Bim data, and all such things come under the operating step of beam data.
Why has Bim become so important?
AEC industry will have to see the things efficiently and smartly to build and design according to the global demand because in future, there will be more population according to the estimate of United Nations and there will be fewer spaces. So efficient and smart work will not just demand for efficient building, but they will also need to be smarter enough to cope with the space available.
Bim does not only allow the teams of construction and design to do the work efficiently, but it also helps them get the data that they prepare during the process to benefit maintenance and operations activities. All these reasons are leading Bim mandates to increase throughout the globe. Famously people call a Scan to Bim service, but it is actually Point Cloud to Bim, and due to this reason as well, people and those interested in Bim services try to look for point cloud Bim services.
What does point cloud mean?
Any set of data points is a point cloud, and those points are there to represent a 3-dimensional object or a shape. Each one has X, Y, and Z coordinates, and these coordinates also come in sets.
In the process of producing point clouds, there is an environment of 3D scanners that take the measurement of many points from the external parts of all surfaces of any object. The technology and technique used in generating point clouds has a high level of surveillance of light detection and ranging, which is also known as LiDAR.
There is a process which is called registration, and this takes place when the scans that come with the help of laser scanners to generate point clouds are stitched together. The scans give rise to having an entire capture of any particular scene leading to the process of registration.
What are the uses of point clouds?
· Point clouds help in creating 3 dimensional CAD models.
· There is going to be a methodology of a quick survey.
· Model quality will be reliable and with full assurance.
· There will be a reduction in site revisions.
· Point clouds also help in having in-depth understanding of any design model.
· All these things lead to cost-cutting in the project of Bim.
Methods of converting point clouds to 3D surfaces?
Point clouds often get converted to CAD models, and many techniques are used for converting any point cloud to a particular 3D surface. Techniques and approaches of Alpha shapes, ball pivoting, etc., help in building a network of triangles over any existing vertical of point cloud. Strategies for converting any particular point cloud to a 3D model depend on the following points:
There should be a complete picture of the number of cloud points for any object.
It is important to register or merge the quality of point cloud if it is more than one.
It is also important to know whether the process is only automatic or it is human supported.
The point to keep in mind is also about the kind of model that will be used for inspection, or visualization.
There will also be a question that whether the model is only about shapes or free forms.
There will be another point that will have to be kept in mind, and that will be about the required accuracy of particular representation.
It is the fact that on the ground, point clouds are there behind Bim process. Point clouds are not just guides or representations, but they have the ability to provide and import 3D physical space effectively into any digital format and give the information to the existing digital models. Importing point cloud is not a heavy and tough task, but it is very user friendly, which makes the process look comfortable and easy to understand.
