How to implement Level of Development (LOD)
How to implement Level of Development (LOD)

Level of Development (LOD) is a crucial aspect of Building Information Modeling (BIM) that has a profound impact on the efficiency and accuracy of your projects. By understanding the different levels of development – LOD 100, 200, 300, 350, 400, and 500 – you can optimize your BIM process and achieve greater project efficiency.

Are you tired of haphazard BIM scopes? Fear not, for I’ve got you covered! Let me walk you through how to implement LOD and how to create custom LODs that are foolproof. Prepare to streamline your BIM LOD scoping process like never before!

Section 1: Understanding LOD

What is LOD and why is it important?

LOD (Level of Detail or Level of Development) defines the complexity and reliability of BIM models via a 100-500 scale.

This scale simplifies communication between BIM modeling teams, clarifying element/component detail for the required BIM purpose at a certain milestone.

LOD can improve BIM planning, budgeting, allocation, communication, collaboration, scheduling, and can help to prevent over modeling and rework.

Overview of LOD 100, 200, 300, 400, and 500

Check out these four images that explain the importance of different Levels of Detail (LOD) for a window’s components. From basic LOD, which only includes window frames, to the inclusion of detailed panes, frames, handles, blinds, and shutters. Each image provides insights into how different levels of detail can impact a window’s BIM requirements and uses. Knowing these LOD differences is critical to avoid over or under modeling.

LOD 100

The first image shows a basic LOD 100 with limited details. The design is simple and there are no decorative elements or textures on display; it only represents the main window opening:

LOD 100 Example

LOD 200

The second image shows LOD 200 for a schematic layout with approximate size, shape, and location – now adding the window frame and rough window panes:

LOD 200 Example

LOD 300

The third image shows LOD 300 for design-specified size, shape, spacing, and location – now adding detailed window frame components, opening details, and even the correct thickness of framing expected:

LOD 300 Example

LOD 400

The fourth image shows LOD 400 with all additional supplementary components added, and even the exact channel sections required for fabrication and field installation:

LOD 400 Example

LOD 500

The fifth image shows a potential example of LOD 500. LOD 500 is an interesting one as it mainly seeks to hold more information rather than additional geometry:

LOD 100 – 500 Summary

So, LOD 100 could show a simple placeholder window, while LOD 200 would add more details like external extents/size and shape. At LOD 300, you might see elements like hinges and a handle, LOD 400 would provide intricate details like screws and weatherstripping, and LOD 500 is focussed on the information that will be important for the life-cycle of the building.

Section 3: Optimizing Your LOD Workflow

So, if you’re searching for a way to smooth out your BIM workflow while ensuring a precise LOD Matrix of requirements, I highly recommend giving Plannerly a try.

Plannerly allows you to easily create and manage LOD BIM requirements in the scope module. It has a built-in LOD library of thousands of predefined assemblies, elements and components!

Plannerly Scope - LOD and ISO 19650 LOIN Definition

Just drag and drop these LOD elements into the scope grid and voilà! Your visual scope is crystal clear, simple, and engaging.

The Plannerly platform also allows you to upload your own custom assemblies for a more tailored set of LOD requirements.

Here are some steps to make the most out of the tool:

  1. Define your BIM Execution Plan (BEP) – with a single click (using the plan module).
  2. Define your LOD requirements – comprehensively define your LOD Matrix requirements according to the necessary level of detail (using the scope module).
  3. Organize and allocate tasks – once you have your requirements in order, Plannerly allows you to assign tasks to each project team.
  4. Collaborate with your team – Plannerly makes working in a team an effortless process, ensuring that everyone sees the requirements and is on the same page.
  5. Auto-check models – Plannerly’s Verify module automatically links and checks that models comply with the contracted scope and information requirements!


Building Information Modeling (BIM) is an essential aspect of any construction project that helps improve efficiency and accuracy. This is where Level of Development (LOD) comes in.

As we learned, in simple terms, LOD describes the level of detail of a BIM model and can be classified on a scale of 100 to 500. Understanding the different LOD levels is crucial for optimizing your BIM process and achieving greater project efficiency.

With Plannerly, you can streamline your BIM process, save time, and achieve superior project outcomes.

3. Here are all the LODs explained

What is LOD 100 in BIM?

LOD 100

LOD 100 refers to the most basic level of development in Building Information Modeling (BIM). This specification is used to create 3D models. A window at LOD 100 will be a simple, rectangular shape with no additional features, while a door would also be a rectangular shape without any hardware details or special characteristics. Typically, LOD 100 is used during the conceptual design phase of a construction project.

What is LOD 200 in BIM?

LOD 200

LOD 200 represents a level of development in Building Information Modeling (BIM), where a virtual representation of a design includes specific details about a model element. For instance, if we consider a window and a door in a proposed building, LOD 200 would indicate that the model correctly portrays the approximate size, shape, and location of these objects. It describes the degree of detail and accuracy included in a BIM during the design and construction phases of a building project, primarily used for design and early coordination purposes.

What is LOD 300 in BIM?

LOD 300 350

LOD 300 represents a key point where the 3D model contains the specifics for elements like windows and doors, including how they start to connection with other objects in the model. LOD 300 can support more automated project management workflows to more accurately report things like cost estimates and quantity takeoffs, making construction more efficient and cost-effective.

What is LOD 350 in BIM?

LOD 300 350

LOD 350 in BIM refers to the level of detail required to specify a product, such as a window or door, for detailed coordination purposes. For example, it would include information on the design, dimensions, framing, and installation of a window. Similarly, for a door, it would encompass aspects like its type, size, swing direction, frames, hardware, and more. LOD 350 represents a detailed level of BIM that includes accurate modeling, assemblies, quantities, and geometry.

What is LOD 400 in BIM?

LOD 400

LOD 400 is an advanced BIM level with precise 3D models that include crucial information on materials, fabrication, installation, performance, and element relationships. It enables detailed cost estimates, energy analysis, and exact material procurement. LOD 400 supports pre-fabrication and on-site construction.

What is LOD 500 in BIM?

LOD 500 Information

LOD 500 in Building Information Modelling (BIM) signifies ‘as-built’ models. For instance, a door will have exact information regarding its material, tolerance, hardware and placement in the building. Similarly, a window will have detailed information about its size, material, placement, and operability. This model makes the information from BIM useful in a building’s operation, maintenance, renovation or retrofit, ensuring accurate and reliable data for all building systems and components.
