Level Of Development (LOD) : Strongest And Supportive BIM Tool

If you are starting up with the project of construction, you will be opting for BIM - Building Information Modeling services. With this you will also come across the acronym which is called LOD. Now you would be thinking as what LOD stands for? So, now with this here is we at Silicon Valley Infomedia Pvt Ltd at your service to update you on LOD services and why is it used.

LOD stands for Level of Development. The term assists in addressing the issues that are arising with the process of construction when BIM is used. This is the process and tool that is used in communicating and collaborating with the team whenever any third person other than the designer wants to extract the information from it. Moving further when the process of design is taking place, the building systems and components progress are seen from a vague concept to a precise and accurate description.

There was a time in the past where there was no designated as well as simple ways available to design the model elements, but if at the designers may know about it, they would not often disclose about it. The reason for the same is very simple, it can easily be misinterpreted in which the element of the model is designed with precision. The process of hand drawings were taken into consideration that was difficult to carry and hence to change this method different tools and software were developed. Hence, now the companies are moving towards the detailed process of detailed LOD BIM models.

We at Silicon Valley Infomedia Pvt Ltd provide you complete and full-fledged services of LOD in BIM. Well, it is not at all wrong in saying that LOD BIM is the strongest root and the base for every project and is a must have service for the construction of buildings, malls, hospitals, etc. And yes, previous the terminology of BIM modeling was not so familiar and known in the market. This is where the designers were not getting the proper accuracy and the authenticity of the models and the designed.

But, with the change in time and technology, the ways and concept of working changed and with this change the work became easy and fast. And of course people have started accepting this new ways of construction methods. Since, we have an in-house team available with the skilled and trained staff we follow the necessary guidelines and the defined codes that are mandatory to be taken into consideration.


At Silicon Infomedia Pvt Ltd, the team of BIM level of development takes the complete understanding from the clients, and based on their needs and requirements confirms each level of developments. At the time of designing and drafting of the project the process of BIM is taken and along with that different LOD’s too. This is defined and termed from from LOD100 to LOD500.

Moving further, we all know that the services of BIM has been used by the designers, drafters, construction firms, contractors, manufacturers, engineers, and architects. With this it would not be wrong in saying that the services of BIM plays an important role and its complete communication is very much helpful in different phases of building designs and models.

It does not matter how complex the project is, the team of professionals assures to resolve the issues with the concept that are defined. These concepts are in the form of 3D visualization, calculations and estimations, Bills of Quantities (BOQs), on-site control of production, fabrications and many more factors. The team creates the models and designs on the basis of the requirement of the project and client both.

Hence, it is the service that gives us the knowledge and keeps us well up-to-date about the planned progress work v/s the actual progress which is ongoing on the site. Also, there are certain levels classified and decided by the American Institute of Architects (AIA) which needs to be followed mandatorily.


Here is the list mentioned below, where we would like to let you know about the different types of LOD that are taken into consideration when the process of designing starts.

BIM LOD 100: Conceptual Design BIM LOD 200: Schematic Design BIM LOD 300: Detailed Design
BIM LOD 350: Construction Documentation BIM LOD 400 / LOD 450: Fabrication & Assembly BIM LOD 500: As-Built and Building Operations


Moving further, below mentioned are the definition of LODs in-depth.

  • BIM LOD 100: Conceptual Design
    This is the first step when there is a start up of the project. Here the model elements are the blocks that are represented by the engineers, designers, and drafters. As this is the start up of the project, it is not necessary that it will have a complete and precise review in 3D geometry. BIM LOD 100 is just the representation of the detailing part. This will not have any shape and size in detail.
  • BIM LOD 200: Schematic Design
    This is the second stage of the model element. In this there would not be any specific details, but this process will give you the update on the size and shape of the model. This means here approximate shape, size, locations, orientations, quantities, etc can be known.
  • BIM LOD 300: Detailed Design
    The third stage of the process that is used for presentation purposes. It can be used in a generic Revit families, basic components in libraries and so on. Here you will find the exact details that are related to the cost, estimations, areas, and the shape of the model. In other words in this stage all the 2D drawings are converted into 3D models.
  • BIM LOD 350: Construction Documentation
    The procedure of this stage includes the detailed models and the elements that are represented in the building element. This is the stage where how the interface of the building will be looking with various systems can be known with the process of graphics and its written definitions.
  • BIM LOD 400 / LOD 450: Fabrication & Assembly
    This model of BIM is to develop and contain detailed requirements that are related to the mean fabrication of different components. Here the process will have fabrication detailing, shop drawings, materials requirements and take-offs, and much more. This is the stage where the process of construction will be started and will have high precision in terms of shape, size, geometry, and cost with smallest and minor details, and there will also be separate drawings which will be meant for construction stage.
  • BIM LOD 500: As-Built and Building Operations
    This is the final stage where you will be getting all the information that is related to the maintenance and operations. Here the complete information of what the actual project will be looking line will be known and how it will be working will be checked. This is irrespective to whatsoever is the size, shape,quantity and so on.

So, with this said we are not only catering the above said services, we are also masters in serving the designs and drafting with the process of Revit LOD 300, Revit LOD 350, and all the BIM LOD levels. One thing that is very much confirmed is that we proceed by checking and considering all levels of LOD Construction along with LOD levels.
