BIM LOD Services USA — LOD 100 to LOD 500 Modeling
We build building information models customized to specific Levels of Development (LOD 100 to 500) from conceptual design to facility operations.
What are BIM LOD services?
BIM LOD services define the Level of Development (LOD) or detail level of a building information model at different project phases. Ranging from LOD 100 conceptual layouts to LOD 400 fabrication-ready models and LOD 500 as-builts, LOD ensures models contain the necessary geometric and attribute data for their intended use.
Managing LOD expectations is critical for project success. If a contractor expects a model ready to extract shop drawings (LOD 400) but receives a basic design coordinate model (LOD 300), structural clashes remain unresolved. Total Engineering Consultants provides clear LOD boundaries, modeling connection bolts, welds, and concrete rebars to exact LOD 400 detailing specifications.
LOD MODELING DELIVERABLES
LOD 100 & 200 (Conceptual & Design)
Developing geometric envelopes, spatial massing layouts, and preliminary member arrangements for design analysis.
LOD 300 (Coordinated Design)
Modeling structural members with exact shapes, dimensions, locations, slopes, and structural coordinates.
LOD 400 (Fabrication Detailing)
Fabrication-ready modeling detailing connection plates, weld symbols, structural bolts, and concrete reinforcement rebars.
LOD 500 (Field-Verified As-Built)
Field-verified models matching actual construction dimensions and containing facility operation system parameters.
OUR LOD DRAFTING WORKFLOW
We systematically increase model detail matching target LOD specifications, ensuring complete coordinate alignment.
Scope Selection
Define the target LOD level (e.g., LOD 300 for coordination, LOD 400 for shop drawing release).
Conceptual Setup
Lay out building envelope grids and coordinate datums based on designs.
Geometry Modeling
Model members (columns, beams, walls) matching the target LOD specifications.
Detailing & Connection
Detail connection assemblies, steel joints, rebar spacing, and embed points for LOD 400.
QA Audit & Export
Review model properties, exporting files (RVT, Tekla, IFC) matching the required LOD checklist.

LOD MODELING FAQS
What are BIM LOD services?
BIM LOD services define the Level of Development (LOD) or detail level of a building information model at different project phases. Ranging from LOD 100 conceptual layouts to LOD 400 fabrication-ready models and LOD 500 as-builts, LOD ensures models contain the necessary geometric and attribute data for their intended use.
What does LOD stand for in BIM?
LOD stands for Level of Development (or Level of Detail). It is a standard framework defined by the AIA (American Institute of Architects) specifying how much detail is modeled in building components at different stages.
What is modeled at LOD 400?
LOD 400 includes all components required for shop fabrication and field erection. For structural steel, it details gusset plates, weld preps, bolts, and holes. For concrete, it details exact rebar shapes, spacing, lap locations, and embedment plates.
How does LOD 500 support facility management?
LOD 500 models are field-verified as-built models. They contain actual coordinates of constructed elements and are populated with asset data, manufacturer details, installation dates, and maintenance links, helping building operators manage systems.
Can you transition a design model from LOD 300 to LOD 400?
Yes. We frequently receive LOD 300 design models from architects or structural engineers and detail them to LOD 400, adding fabrication-ready joints, welds, bolts, and rebar schedules to release shop drawings.
