BIM Best Practice Guidelines

The adoption of Building Information Modeling (BIM) represents more than just a change in software—it’s a fundamental shift in how projects are conceived, coordinated, and executed. As firms move from traditional CAD-based workflows to data-rich, integrated BIM environments, one of the most critical—but often underestimated—components of this transition is model management.

Model management is not just about keeping the BIM file organized; it's about maintaining the integrity, usability, and collaboration potential of the model throughout the entire project lifecycle. And as the shift to BIM reshapes every aspect of the design and construction process, effective model management becomes essential to success.

A Shift in Workflow, Not Just Tools

One of the first realities firms must face during the BIM transition is that the workflow changes dramatically, regardless of which BIM authoring tool is used (Revit, Archicad, Vectorworks, etc.). BIM is not a drawing tool—it’s a data-driven process that supports smarter decision-making, early coordination, and lifecycle thinking.

What’s changing:

• More information is being generated and exchanged earlier in the design process than ever before.

• The lines between design phases blur, as schematic decisions require a level of detail that was once reserved for later stages.

• The role of team members shifts, with architects, consultants, and contractors contributing to and depending on the model sooner and more intensively.

Without proper model management strategies in place, this influx of early-stage data can lead to confusion, versioning issues, misalignment between teams, or even rework, ultimately defeating the purpose of adopting BIM in the first place.

Reevaluating the Entire Project Ecosystem

The implications of BIM reach far beyond the digital workspace. The way teams bill, collaborate, and define responsibilities must also evolve. This means model management isn’t just an internal file maintenance task—it’s a strategic coordination role that connects technical workflows with business processes.

Key areas impacted:

• Billing and Fee Structures:
  Traditional fee models may no longer align with the upfront work required in BIM. Since significant effort now occurs early in the project, billing structures must reflect front-loaded design activities.

• Consultant Involvement:
  Engineers, fabricators, and specialty consultants must be engaged much earlier than in CAD workflows. Their input is critical to accurate modeling, clash detection, and systems coordination during design development, not just during documentation.

• Client Expectations:
  Clients may expect higher-fidelity models, earlier visualizations, or simulations like energy modeling or cost forecasting, further emphasizing the need for a well-managed, centralized model from day one.

What Effective Model Management Looks Like

To navigate this transition effectively, firms need to establish robust model management protocols. These protocols ensure that the BIM model remains a single source of truth that is clean, accurate, and usable across all stages and disciplines.

Best practices include:

• Defined naming conventions and file structures

• Consistent modeling standards and templates

• Regular model audits and cleanup routines

• Clear responsibilities for model ownership and updates

• Use of collaboration platforms (e.g., BIM 360, ACC, Navisworks) for coordinated access and clash detection

Firms should also consider assigning a BIM Manager or Model Coordinator—a dedicated role responsible for overseeing modeling standards, training, and coordination between internal teams and external stakeholders.

The Strategic Value of Model Management

When model management is taken seriously, the benefits are substantial:

• Fewer coordination errors and RFIs

• Faster decision-making through centralized data

• Improved collaboration across disciplines

• More accurate cost and quantity takeoffs

• Better construction outcomes and client satisfaction

In contrast, poor model management leads to fragmented information, miscommunication, and avoidable delays that can erode both project margins and stakeholder trust.

The Importance of Model Management in the Era of BIM

A successful BIM project doesn’t begin with the first modeled wall or floor—it begins with preparation and consistency. Before a single element is placed in the model, your team should have a well-defined framework in place that promotes standardization, efficiency, and collaboration.

The use of project templates, family templates, and content libraries is essential to ensure every project is developed with a consistent look, behavior, and performance. These foundational tools reduce rework, streamline documentation, and uphold firm-wide design standards.

Let’s take a closer look at the key components that should be established before the project begins.

1. Project Templates: The Blueprint for Consistency

Project templates are the cornerstone of a standardized BIM workflow. By predefining core settings, styles, and content, templates allow teams to hit the ground running on any new project, while maintaining consistent functionality and aesthetics across the board.

It is recommended to create multiple project templates tailored to different building types or market sectors—such as healthcare, commercial, or religious facilities—since each may require unique standards and content.

Your project templates should include:

🔹 Annotation & Dimension Styles: Standardize text styles, leader settings, and dimension types to ensure visual consistency across drawings.

🔹 Drafting Views: Include commonly reused drafting views, such as code graphics, wall section frameworks, or detail callouts. These can serve as placeholders or development platforms for future detailing.

🔹 Families

• System Families: Preload the 5–10 most commonly used types, such as walls, floors, ceilings, and roofs.

• Component Families: Limit these to elements that are used on almost every project—like standard doors, windows, or casework. Avoid overloading the template with rarely used components.

• Ensure that all included families have correctly defined shared parameters to support schedules, tags, and keynotes.

🔹 Fonts: Set and lock standard fonts to ensure branding and documentation remain consistent.

🔹 Import/Export Settings: Define DWG, IFC, and PDF export settings in advance to avoid inconsistencies during consultant coordination or final delivery.

🔹 Legends: Include standard legends like:

• ADA clearance diagrams

• Project abbreviation lists

• Typical material symbols

🔹 Line Styles, Weights, and Patterns: Control the graphic language of your drawings by predefining these styles. This maintains clarity and professionalism in construction documents.

🔹 Object Styles: Standardize how model elements appear in views by setting object styles by category and subcategory.

🔹 Phasing: If applicable, configure project phasing, including phase filters, graphic overrides, and view settings, to support renovations, additions, or staged construction.

🔹 Project Browser Organization: Customize the browser to categorize views by discipline, stage, or use (e.g., Working Views vs. Sheet Views). This helps team members quickly locate the right information.

🔹 Schedules: Preload commonly used schedules (e.g., window, door, room finish schedules) with formatted headers, filters, and calculated fields so that they populate automatically as model elements are added.

🔹 Sheets: Include example sheets like:

• Cover page with title, project location, and logos

• Typical floor plans and ceiling plans

• Placeholder sheets for details and elevations

🔹 Tags: Load in standard tags for doors, windows, rooms, and materials. Make sure they align with your firm's documentation standards.

🔹 Title Blocks: Include standard title blocks in common sizes (A1, A2, E1, etc.) with integrated fields for:

• Project name and number

• Sheet title and number

• Revisions

• Company branding/logo

🔹 View Templates: Preset visual styles for various view types (e.g., architectural plan, structural plan, RCP, 3D presentation). These help maintain visual consistency across the entire drawing set.

💡 Best Practice Tip: Avoid bloated templates. Use a minimalist approach—only preload content and settings that are universally needed. The goal is to reduce startup time, not slow down performance or increase clutter.

2. Family Templates: Standardizing Custom Content Creation

While project templates guide overall model development, family templates control how custom elements are created. The default out-of-the-box Revit family templates are a good starting point, but they can and should be refined to match your firm’s standards.

Consider:

• Adding reference planes, standard parameters, and annotation labels to reduce repetitive setup work.

• Creating custom family templates for specific building elements that are often repeated across projects, such as restroom accessories, casework modules, or lighting fixtures.

• Reducing reliance on in-place families, which are harder to control, less efficient to edit, and cannot be easily reused across projects.

Establishing consistent family templates ensures your internal content library grows in a controlled, predictable, and maintainable way.

3. Content Libraries: Organizing the Building Blocks

A well-organized content library saves time, reduces duplicate efforts, and ensures your team always works with approved, reliable components. In addition to the default Imperial Library, create supplemental content libraries that store both manufacturer content and internally developed elements.

Organize content into categories such as:

• Component Families (Doors, Windows, Furniture, Casework)

• Detail Components (2D elements for construction details)

• Profile Families (Custom shapes for walls, sweeps, railings)

• Material Libraries (Standardized appearances and physical properties)

• System Families (Stored in project files for Walls, Floors, Roofs, etc.)

• Template Files (Both project and family templates, organized by discipline or building type)

🗂️ Consider using shared network folders or BIM content management platforms (like UNIFI, Avitru, or BIM360 Docs) for scalable and remote-accessible library management.

Establishing a strong foundation before the project begins is the hallmark of a professional and future-ready BIM practice. By developing thoughtful project templates, refining family creation standards, and maintaining organized content libraries, you set your team up for consistent performance, high-quality documentation, and smoother project delivery.

Remember: Preparation is not overhead—it’s a long-term investment in efficiency, consistency, and quality.

Before the Project Begins:
Laying the Foundation for BIM Success

Starting a BIM project correctly is one of the most important steps in ensuring its long-term success. While templates provide a solid foundation, every project requires a set of initial setup tasks tailored to its unique scope, scale, and complexity. These foundational actions create structure, reduce confusion, and establish consistency across the team from the very beginning.

Once a new project has been created using the appropriate company-approved template, the following best practices should be followed to guide the design team and ensure optimal organization, performance, and collaboration throughout the project lifecycle.

1. Project Folder and File Structure

Proper digital organization begins outside of the BIM model—with the folder and file setup on both the server and users’ machines. Establishing a clear and consistent structure from day one prevents misplaced files, naming conflicts, and unnecessary delays during collaboration.

🔹 Server Setup

Create a dedicated folder structure on the company or cloud server that includes:

• Central File location: The live Revit central model for worksharing.

• Consultants’ Files: A dedicated space to store architectural, structural, MEP, and civil models received from external teams.

• Linked CAD/IFC Files: Reference drawings, surveys, or manufacturer-provided content.

• Project-Specific Families: Custom families created for the current project.

• Exported Deliverables: PDFs, DWGs, IFCs, or rendered visuals for client or consultant use.

• Archived Versions: Regularly saved milestones or backups for audit or rollback purposes.

🔹 Workstation Setup

Encourage team members to organize local files consistently:

• Create a local copy of the central model using defined worksharing protocols.

• Maintain a consistent directory structure to store temporary files, exports, and linked content.

• Use standard naming conventions for all local copies to avoid overwriting or miscommunication.

💡 Tip: Document the folder structure in a shared project kickoff guide to ensure everyone follows the same format.

2. Model Position and Extents

Defining the spatial and geographic setup of the model early on is critical. This ensures accurate coordination with other disciplines, supports analysis tools (like solar studies), and provides a reliable reference framework for the design team.

Key steps include:

• Set the Project Origin:

  Choose a logical model origin point, such as the corner of a building or the center of a site.

  Decide between using the Internal Origin, Project Base Point, or Survey Point, depending on project type and site coordination needs.

• Establish True North and Project North:

  Project North aligns the model for drafting clarity (e.g., aligning the building with sheets).

  True North matches the building's orientation on the actual site for sun studies, site coordination, or geolocation-based analysis.

• Input Location Data:

  Define the project’s geographic location to accurately simulate solar positioning, shadows, and weather effects.

• Add Levels and Grids:

  Set up vertical levels according to building stories or key elevations.

  Add grid lines to define structural bays or modular dimensions—these guide modeling and coordination across disciplines.

💡 Tip: Coordinate with the surveyor early to lock in geolocation settings, especially on large or complex sites.

3. Model Organization

An organized model is easier to navigate, manage, and collaborate on. Proper model structuring prevents confusion as teams grow and project data becomes more complex.

Steps to organize your model:

• Add Worksets:

  Enable worksharing and define worksets based on building systems, disciplines, or physical zones.

  Examples: Core & Shell, Interiors, Site, Structural, MEP, Shared Levels, and Grids.

• Define Project Phases:

  Set up construction phases (e.g., Existing, Demolition, New Construction, Future) to support renovation or multi-stage projects.

  Apply appropriate phase filters and graphics to views.

• Set Up Design Options (if needed):

  If the project includes alternate design scenarios (e.g., layout options), define them early to streamline decision-making and prevent model confusion.

• Adjust Browser Organization:

  Modify how views, sheets, and families appear in the Project Browser to match the team’s workflow. For example, separate working views from documentation views, or group views by discipline.

• Create or Load Shared Parameters:

  Add any necessary shared parameters that were not included in the base template to ensure consistent data tagging and scheduling.

• Load the Keynote File (if applicable):

  Connect the model to your firm’s standardized keynote database to automate annotations in detail and construction drawings.

4. Model Views: Setting Up the Design Environment

Before jumping into design, it’s essential to create the necessary working and documentation views that allow different teams to engage with the model effectively.

Recommended views to create or verify:

• Floor Plans: Architectural plans for each level.

• Ceiling Plans: For lighting and HVAC coordination.

• Elevations and Sections: For both design development and documentation.

• 3D Views:

  General 3D overview of the building.

  Camera views for design reviews or presentations.

  Isometric views of key areas (e.g., mechanical rooms, lobbies).

• Drafting Views:

  Placeholder views for standard details not linked to the model.

  Reusable 2D graphics, like codes or accessibility diagrams.

• Schedules:

  If not already present in the template, create project-specific schedules such as Room Finish, Equipment, Door, or Window schedules.

  Ensure schedules are filtered, sorted, and formatted to align with project documentation standards.

💡 Best Practice Tip: Apply the correct view templates to working views and documentation views right away to maintain consistency and avoid manual overrides later.

Taking the time to carefully set up your BIM project at the very beginning pays dividends throughout design, documentation, and construction. By following these best practices for project startup, you ensure:

• A clean, organized model structure.

• Clear collaboration paths across teams.

• Accurate representation of site, levels, and project phases.

• Reduced rework and coordination issues down the line.

Think of this stage as laying the digital foundation—the stronger it is, the more smoothly your project will grow.

Starting a Project in BIM:
Best Practice

Efficient BIM modeling requires balancing model complexity with hardware capabilities to maintain performance and usability. Below are the core principles and best practices to optimize Revit model performance.

1. Model Complexity & Performance Factors

Performance is affected by:

• Complex geometry

• Multiple parametric relationships and constraints

• Numerous linked files

2. General Best Practices

• Minimize unnecessary model elements such as unused area schemes or overly detailed geometry.

• Limit constraints to reduce conflicts and sluggish model behavior.

• Avoid excessive use of Copy/Monitor—apply only where synchronization is essential (e.g., levels and grids).

• Delete unused design options once decisions are finalized.

• Use generic components (e.g., walls, windows) during early stages or in less critical areas.

3. Families and Groups

• Use parametric families selectively: balance flexibility and resource use.

• Avoid over-modeling 3D geometry unless necessary.

• Use Groups only when beneficial, and delete unused groups from the model.

• Optimize family templates to reduce complexity and size.

4. Detailing and Line Use

• Detail lines: for view-specific 2D graphics.

• Model lines: for elements appearing across multiple views.

• Scale detailing appropriately to the output scale (e.g., ¼” = 1’-0”).

5. Importing & Linking

• Unload or remove unused links (DWG, images, Revit models) to improve performance.

• Use linked models for large projects, following best practices for model splitting.

6. Components & Assemblies

• Railings and stairs: avoid over-detailing in 3D; supplement with 2D details.

• Joined geometry: limit use to essential connections.

7. Views & Visualization

• Delete unused views to declutter the model.

• Adjust view range to the minimum required depth.

• Use Close Hidden to improve memory efficiency.

8. Model Splitting

Split models only when necessary, and ideally during early project phases. Common reasons include:

• Campus-style projects (multiple buildings)

• Geographically dispersed teams

• Exceptionally large file sizes

• Naturally phased projects

⚠️ Model splitting is a last resort—exhaust all other performance practices first.

9. Volumes & Calculations

• Turn off volume calculations unless needed for analysis (especially in Revit MEP).

• Use "Areas only" mode to reduce overhead.

10. Worksets & Worksharing

• Use worksets strategically:

  To load only what’s needed (performance)

  To control user access (security)

  For task management and offline work

• Avoid creating too many worksets—it can complicate management.

• Synchronize with Central regularly and recreate local files after prolonged absences.

• Use Worksharing Monitor to track team activity and file health.

Efficient modeling in Revit isn’t about doing more—it’s about doing the right amount. By following these best practices, teams can ensure performance, clarity, and collaboration throughout the lifecycle of a BIM project.

Modeling Efficiently in BIM: Key Takeaways

Maintaining a healthy Revit project file is essential to preserving performance, stability, and collaborative efficiency throughout the lifecycle of a BIM project. As models grow in complexity and size, so do the risks of file corruption, slow performance, and miscommunication across project teams. Implementing a structured file maintenance routine is crucial, especially for large or long-duration projects.

While small projects may not require intensive maintenance schedules, larger models or collaborative projects across multiple teams and disciplines must be actively managed. These practices apply not only to in-house files but also to consultant models received externally.

1. Periodic File Maintenance (e.g., At Each Sheet Set Issue)

During major project milestones—such as issuing a sheet set—perform a full round of file maintenance. This process helps reset and stabilize the central model, particularly after heavy design and documentation activity.

Tasks:

• Audit the central file
  Checks and repairs corrupt elements, broken links, and file integrity issues.

• Back up the central file
  Protects against data loss and enables recovery if corruption occurs.

• Create a new central file
  Helps remove unnecessary file bloat and restores optimal performance.

• Instruct all users to create new local files
  Ensures compatibility with the updated central model, avoiding synchronization issues.

💡 Why this matters: Frequent auditing and re-creation of central files reduce risks of corruption and slow performance caused by accumulated file history or outdated local files.

2. Weekly Maintenance

Weekly file maintenance helps keep the model lean and conflict-free. This is essential during phases of intense collaboration or rapid model development.

Tasks:

• Audit the central file
  Routine integrity check to prevent larger issues.

• Coordination Review (if working with consultants in Revit)
  Ensures external model links (e.g., MEP, structural) are updated and coordinated.

• Interference Check (if used)
  Detects geometry collisions that could lead to constructability issues.

• Review and resolve warnings
  Minimizes Revit’s internal errors that may cause performance lags or printing issues.

• Delete unused/redundant views
  Reduces file size and declutters the Project Browser.

• Purge unused elements
  Eliminates families, types, materials, and other assets not currently in use.

• Compact central and local files
  Rewrites the file to remove fragmentation, enhancing stability and speed.
  

⚠️ Note: Be cautious when purging—retain anything that may be reused in future project phases.

3. Backups and Archiving

Regular archiving protects the project's development history and satisfies record-keeping standards for compliance or future reference.

Tasks:

• Create archives at each major issue date
  Use Detach from Central to create a standalone file, effectively freezing the model in its issued state.

• Use local files as backups when needed
  If a central file becomes corrupt, convert the most up-to-date local file into a new central file. This is often quicker and more accurate than trying to restore from automatic backups

💡 Best Practice Tip: Label archived files with clear naming conventions (e.g., ProjectName_IssueSet_Date) and store them in a dedicated archive folder on the server.

Final Thought:
Modeling Smart, Not Just More

Efficient modeling in Revit isn't about modeling everything—it's about modeling intentionally and strategically. The goal is not to showcase every detail, but to create a model that serves its purpose effectively: whether that’s design iteration, documentation, analysis, coordination, or construction.

Ultimately, modeling efficiently is about balance—between detail and simplicity, between speed and accuracy, and between individual creativity and team-wide consistency. By doing the right amount of modeling, teams can focus on design excellence and project delivery without being bogged down by the software.

"Work smarter, not harder" applies perfectly to Revit modeling. A well-managed BIM model is more than a 3D file—it’s a reliable, dynamic tool that supports decision-making, collaboration, and success across every stage of a project.
