Need a defined BIM modeling or coordination package?
Share the available drawings, models, BIM Execution Plan, LOD requirements, disciplines and coordination priorities for a technical scope review.
What Do We Need to Start a BIM Project?
A clear BIM scope begins with the available design information, required model uses, LOD expectations, coordination responsibilities and project standards. Defining these inputs early helps establish the correct model setup, review process and deliverables.
| Client provides | Optimar delivers | Used for |
|---|---|---|
| PDF, DWG or design models | Revit discipline models | Model development |
| BIM Execution Plan | Project-aligned model setup | Project standards alignment |
| LOD requirements | Defined model detail | Stage-specific delivery |
| Architectural, structural and MEP models | Federated BIM model | Coordination |
| Clash rules and priorities | Clash reports and issue tracking | Coordination meetings |
| Markups and revisions | Updated model package | Review cycles |
Final outputs depend on the verified source information, project responsibilities, required software versions, model uses, LOD requirements, exchange formats and agreed review stages.
Model detail should follow the required project use
LOD requirements should be confirmed by discipline, element, project stage and intended use rather than assuming every model component requires the same level of development.
Project requirements reviewed before model production
The BIM setup is based on the requirements supplied for the assignment rather than a generic production template.
- BIM Execution Plan and project BIM standards
- Required Revit and coordination-software versions
- Coordinates, levels, grids and model breakdown
- Discipline responsibilities and model ownership
- LOD expectations and intended model uses
- Clash rules, tolerances and coordination priorities
- Naming, file exchange and submission requirements
BIM models can also begin with verified scan data
Where existing conditions form part of the scope, laser scans and point clouds can be interpreted into structured BIM geometry through Point Cloud to BIM Services . The required model detail and tolerance should be agreed before production begins.
Have a BIM Execution Plan or LOD requirement?
Share the available project information, disciplines, model uses, coordination requirements, required software versions and target deliverables for a technical scope review.
How BIM Coordination Works on a US Construction Project
Effective BIM coordination requires more than running clash tests. The project team must first define model responsibilities, federation rules, clash priorities, review cycles and the process for recording and resolving coordination issues.
From discipline models to reviewed coordination outputs
The exact sequence follows the project BIM Execution Plan, coordination schedule and responsibility matrix, but a typical workflow includes the following stages.
Model intake
Confirm file versions, coordinates, disciplines, revision status and required coordination inputs.
Federation
Combine the agreed architectural, structural and MEP models into the coordination environment.
Clash testing
Apply the agreed clash rules, tolerances, system priorities and exclusion criteria.
Issue review
Classify relevant issues, prepare viewpoints and record assigned coordination actions.
Revision cycle
Incorporate approved decisions and repeat coordination checks against updated model versions.
What can be checked during model federation?
Coordination rules should be defined around the systems, tolerances and construction interfaces relevant to the project.
- Hard geometry clashes
- Required clearance zones
- Structural penetrations
- Ceiling and plenum interfaces
- Riser congestion
- Plantroom access
- Equipment maintenance zones
- Routing conflicts
- Trade interfaces
- Model alignment and coordinates
BIM support changes as the project information develops
The required model detail and coordination activity should follow the project stage and intended use rather than applying one fixed BIM scope from beginning to end.
Design development
Discipline model development, model setup and early interface coordination.
Construction documentation
Detailed modeling, coordinated drawing outputs and information updates.
Trade coordination
Federated review, clash testing, routing coordination and issue-management cycles.

BIM Software, File Formats and Model Review
Building Information Modeling services depend on more than model authoring software. File versions, coordinates, project templates, model health, exchange requirements and review procedures all need to align with the project’s BIM Execution Plan and delivery standards.
Software selected around the required project workflow
Exact software releases and exchange settings are confirmed before production so that models can be reviewed and incorporated into the client’s established coordination environment.
Autodesk Revit
Architectural, structural and MEP model authoring, model-based drawings, schedules and Revit modeling support.
Navisworks Manage
Model federation, clash testing, viewpoints and multidisciplinary coordination review.
Autodesk Construction Cloud

Common BIM exchange formats
Required versions and export settings should be confirmed before the first model exchange.
- RVT
- RFA
- IFC
- NWC
- NWD
- DWG
- DXF
- BCF
- COBie when specified
Model checks before each agreed information exchange
The review process is adapted to the project requirements, disciplines, model uses and submission criteria rather than relying on one generic checklist.
- Confirm source files, revisions and project requirements.
- Check coordinates, levels, grids and model setup.
- Review model geometry against the supplied design information.
- Check agreed parameters, naming and file organization.
- Run discipline and federated coordination checks as required.
- Complete an internal review before the agreed model exchange.
