BIM Level of Development (LOD)

OlilO has expertise of delivering LOD for different levels. We adopt internationally accepted standard for Level of Development. These development models are purpose built in various stages of design, 3D visualization, estimations, fabrication, scheduling, construction-caliber quantities, and on-site production control.

LOD 100 - Concept Design

The building 3D model is developed to represent the information on basic level. Thereby, only conceptual model creation is possible in this stage. Parameters like area, height, volume, location and orientation are defined

LOD 300 - Detailed Design

Accurate modeling and shop drawings where elements are defined with specific assemblies, precise quantity, size, shape, location and orientation. Here too we can attach non- geometric information to the model elements

LOD 350 - Construction Documentation

It includes model detail and element that represent how building elements interface with various systems and other building elements with graphics and written definitions

LOD 500 - As-Built

Elements are modeled as constructed assemblies for Maintenance and operations. In addition to actual and accurate in size, shape, location, quantity, and orientation, non-geometric information is attached to modeled elements



OlilO's LOD Services

We create simple models with lower LOD that can generate clash detection reports, produce Quantity takeoff and fabrication models to extract shop drawings and spools. The BIM's Level of Detail (LOD) - defines how the 3D geometry of the building model can achieve different levels of refinement, is used as a measure of the service level required. OlilO offers five LOD options ranging from 100 to 500. Using the Level of Detail (LOD) industry specifications as a guide, OlilO's 3D Modeling Service will create a 3D model of your projects based on the specificity required. We also deliver animation services for LOD in the sequence for virtual construction sequencing and simulation to develop insights of how and what will be constructed.

The Level of Development (LOD) Specification is a reference that enables practitioners in the AEC Industry to specify and articulate with a high level of clarity, the content and reliability of Building Information Models (BIMs) at various stages in the design and construction process. The LOD Framework addresses various issues faced by AEC professionals by providing an industry-developed standard to describe the state of development of various systems within a BIM. This standard enables consistency in communication and execution by facilitating the detailed definition of BIM milestones and deliverables.
