Some of the LOD 400 Projects delivered by United BIM



LOD 400 BIM Modeling Built for Construction Execution
Our LOD 400 BIM services develop highly detailed models that support fabrication, assembly, installation, and field coordination. At this level, model elements are developed with precise geometry, dimensions, quantities, locations, interfaces, and construction-specific detailing for production-ready deliverables.
We create LOD 400 BIM models for project teams that need more than design-level representation, structured to support shop drawing development, procurement planning, fabrication workflows, installation sequencing, and clash-free coordination across trades.
Model elements are no longer generic representations- they carry fabrication and installation-level accuracy.
Detailed information reduces ambiguity before work reaches the site, minimizing costly field changes.
Models are structured to generate shop drawings, support manufacturing, and align with BIM Execution Plans.
Trade-specific models are reviewed for constructability, access conditions, and coordination conflicts.
BIM LOD 400 Scope Across Multiple Disciplines
We provide fabrication-ready LOD 400 models across all major construction disciplines with
full trade-specific detailing.
Fabrication and installation-level detailing for drywall, finishes, millwork, specialty equipment, gutters, storefronts, doors, and windows.

Our LOD 400 BIM Modeling Process
01
Requirement ReviewReview of drawings, specifications, addendums, standards, and BIM execution requirements.
02
Scope DefinitionDefine trade scope, expected LOD, deliverables, and coordination requirements per project.
03
Detailed ModelingDevelop fabrication-level BIM models with required geometry, interfaces, and installation details.
04
Coordination ReviewCheck for coordination, access, support conditions, and constructability issues across trades.
05
Final DeliverablesDeliver coordinated models, shop drawing support, and fabrication-ready outputs aligned to project needs.
Yes, and that's the expectation on every project. We model to your BEP, including your naming conventions, your file structure, your element information requirements, and your deliverable formats. If your BEP references the BIMForum LOD Specification, GSA BIM guidelines, or a state-specific mandate (like Connecticut DAS), we are already familiar with those frameworks.
Primary delivery is Revit (.rvt), coordinated and structured for shop drawing extraction. We also deliver 2D fabrication and shop drawings in DWG and PDF. If your fabrication team uses a specific sheet format or title block standard, let us know before modeling begins and we will align our output accordingly.
Full multi-trade coordination and clash detection are included in our LOD 400 scope. It is not a separate line item. You receive a clash report with every delivery set. Clashes are categorized by severity and trade pair, and we coordinate resolution before delivering the final model.
We manage this through agreed revision cycles built into the project timeline. We track design change documentation against the model scope and flag impacts on LOD 400 elements before absorbing changes. For fast-moving projects, we can structure weekly model sync cycles to keep pace with design evolution.
Yes. We regularly take over in-progress models from other BIM teams. We start with a model audit to assess what has been built to standard, what needs to be corrected to LOD 400, and what is missing. We will tell you what the remediation scope looks like before we take it on.
Yes. United-BIM is a certified SBE/MBE firm and has experience with federally funded project BIM requirements, including GSA BIM standards. We are also registered under DUNS 081321190 and can provide relevant compliance documentation on request.
