Level Of Detail (LOD): Understand And Utilization

Have you ever heard about the term LOD? Or what does LOD stands for? Why it is undertaken? Well, no more brainstorming. Here is the answer to all your queries and concerns. Today, what we are discussing is the key factor of LOD along with differences at each of its levels.

Any construction project that is outsourced, is incomplete without utilizing LOD. Based on the project needs and requirements the team undertakes different LOD. These are ranging from LOD 100, LOD 200, LOD 300, LOD 350, LOD 400, and LOD 500.

Types Of LODs

LOD 100 – Conceptual Design

The beginning of the project is initiated with the undertaking of LOD 100. It is known as one of the traditional conceptual design phases. This is the level that helps deliver the physical information that is possible for making a project successful. With the help of necessary BIM tools and technology, the model data is created with detailed understanding and analysis.

LOD 200 – Schematic Design

To develop the design and model of the project, LOD 200 is taken into consideration. It is the phase that helps transform the conceptual design that is associated with the model. This model further is available for the creation of construction documents. In simple words, we can say that this is the longest phase of the project in which any model has to undergo both traditional and modern architectural design development efforts.

LOD 300 – Detailed Design

When it comes to getting the model element of the project, LOD 300 is utilized. It is the process in which the element is graphically represented in the model itself. The representation of the model was included to get information like quantity, size, shape, location, and orientation. This will further continue with the non-geographical information that is attached to the model element.

LOD 350- Greater Details And Construction Documentation

The details of the construction documentation are more precise and in-depth. It is the art of work that the AEC companies demand to represent the building model. It delivers the interface of the design and various building systems. It further continues by delivering other elements that have written information and graphical data.

LOD 400 – Fabrication And Assembly

The achieving of LOD 400 is possible with the fabrication and assembly of the model. This is the process that is directly extracted from the BIM model. The process of LOD 400 is utilized for scheduling and coordinating the project phases.

The common stage of development here is derived from the design information. From different CAD platforms, the fabrication model is designed and developed. The technology and fabrication level are different from that required in the project. 

LOD 500 – As-Built 

The final stage of the project contains all necessary building elements. It is the stage that is undertaken at the post-construction level. The hand-over of the project when delivered is handed over to the facility managers who are maintaining the records of the life-cycle management of the building.

Moving further, it is also said that the utilization of LOD is more precise and accurate. The higher is the use of LOD, the outcome is more detailed. The complete feature and deliverables are described on one single element that is part of the BIM model.

Also, understanding the project’s needs and requirements it is the BIM engineers who help them with customized LOD. The entire process thus is simplified and represented in a form that adds value to the work and its operational functions.
