What do we understand by the term ‘BIM’

BIM is an abbreviated form of Building Information Modeling, which is a process supported by various technologies, contracts, and tools which involve management and generation of digital representations of function and physical characteristics of places and locations. In this article, we will also understand the full concept of Scan to Bims well.

As far as Bim is concerned, building information models, which we can call in updated form as Bim, are basically computer files that can be extracted, networked, or changed to give support to decision making about a built asset.

The development of the Bim concept has been there since the 1970s, but it became hugely widespread only in the early 2000s.

What is the history behind the concept of Bim?

As mentioned earlier, the concept of Bim got its beginning in the 1970s, and the tools which were the software tools got first developed for modeling buildings, and got emerged in the late 70s and 80s.

The early software products for the sake of the process of Bim included RUCAPS (Riyadh University Computer-Aided Production System), Gable 4D Series, which was a computer aided design package, Reflex, which was a building design software.

The term of the building model, which is used in today’s sense as Bim, was used in the papers for the first time only in the mid-1980s. The early software applications and hardware which were present were very costly, which made the widespread limitation for adoption.

Basically, the Bim concept is not attributed to any one particular person, but the innovation of the Bim concept came from central and northern Europe, the United States, and Japan as well.

Understanding the concept of scanning

For better understanding, it is not going to be a difficult task for us to define scan for you. Because in the Scan to Bim process, there is an involvement of a laser scanner . That laser scanner comes as the method of capturing 3D scan with full accuracy of any real-world conditions for a particular purpose of a project.

There are devices that we can call scanners, which help in the analysis for the real object to collect data about its appearance, color, and shapes. Such data helps in creating a point cloud on the surface of any object. If a particular scanner is used for the sake of scanning a building, that scanner will be called as building scanner.

Various types of scanners

Lots of different types of scanners are available, and scanning systems help in getting the data of a particular site and location in a great way. Some of the scanning methods through scanners are as follows:

Airborne laser scanning

It is basically used for capturing the data of the earth surface. Let’s understand some of the ideal usages of this airborne laser scanning.

· It helps in the scanning of exterior mapping.

· It also does a great job in the scanning of the corridor.

· This airborne laser scanning can be used for large scale mapping as well.

Mobile Mapping

Through mobile mapping, the scanning helps in the collection of survey quality point data accurately and quickly. Let’s understand some of the ideal usages of mobile mapping.

· Mobile mapping helps in rapid exterior mapping for corridors.

· It is also used for asset management, disaster management, utilities planning, etc.

Time of flight

This kind of scanner helps in picking interior high-density scan. The scans may capture the architectural, structural as well as forensics scans. Let’s understand some of the ideal usages of time of flight.

· Time of flight is used to get gesture recognition.

· Along with object scanning, time of flight also helps in object tracking.

How does the concept of Scan to Bim stand before us?

It is going to be a very usual and ordinary thing for AEC professionals as far as the process of Scan to Bim is concerned because Scan to Bim process involves 3D laser scanning of any particular site and physical space for the creation of an accurate digital representation. And the depth representation that comes out of the process is thereafter used for assessing, designing, and evaluating options. There are three very simple steps of the scanning process that are mentioned as follows.

  • The first step is about collecting the data with the help of a 3D laser scanner.

  • The second step includes bringing about the data back to the design office.

  • The third step becomes the most useful thing for using the same data in the process of building information modeling.

Reasons to use 3D laser scanning

As far as using 3D laser scanning is concerned, it helps in the collection of the data of as-is conditions of any particular structure or building. The data provides accuracy and the latest features of the structure or building. The data includes different designs of the structure as well as the construction stages of the structure.

Bim laser scanning does not just help in the essential collection of the data of a particular building, but it also helps in the verification of as built models with the latest technology. The most important requirement comes about point cloud, which is possible only through a 3D laser scanning. Some of the things that are used very frequently in the process of Scan to Bim include a tripod and eye-safe laser, which rotates at a very high speed.

The teams that have been working on a particular project for the sake of the Scan to Bim process don’t necessarily need to visit a particular site or location again and again to collect the data. This means there’s a less pressure of visiting a site again and again and doing it to authenticate the data. Once the scanning is done properly, the number of visits usually comes down, and there may not be any requirement of the second visit to the location.

Scan to BIM process does not just help in collecting the data, but sharing of the information in a very fast manner is also one of the things of attraction to go through the process of Scan to Bim. There is less time which takes in the collection of data, which helps it become very efficient.

The most fundamental and vital thing for the people to understand is about the degree of human error, which is reduced because there is an environment of the process of Scan to Bim. This is completely in contrast with the traditional method of as-built documentation process because that process used to take a lot of time but did not use to give the type of output which was required.

Final Point

In this article, we have tried our best to give you the complete comprehension of scanning as well as Scan to Bim. Building information modeling and scanning process go hand in hand because these two things are interconnected and interrelated. The model of building information which is used in the present era has been so successful that acquiring accuracy about the data of any structure or building no longer remains a complicated and difficult task.
