How to Compare Drawings in Procore

Understanding Drawing Comparisons

Keeping track of drawing revisions is crucial in construction project management. Whether you're an architect, engineer, or project manager, having the right tools to compare revised drawings can help you understand design changes, identify discrepancies early, and reduce the risk of costly rework. Procore's drawing comparison feature allows you to overlay two drawing versions so you can clearly see what has been updated, added, or removed.

Drawing comparisons play a vital role in maintaining project accuracy. When team members can quickly identify changes between versions, they can make informed decisions and avoid potential conflicts. This visual approach to revision management saves countless hours that would otherwise be spent manually reviewing documents line by line.

The ability to compare drawings digitally also enhances collaboration across teams. Project stakeholders no longer need to be in the same physical location to review changes together. With Procore's cloud-based platform, everyone can access the same comparison view regardless of their location, ensuring alignment across the entire project team.

Benefits of Comparing Drawings

Understanding why drawing comparisons matter can help you leverage this feature more effectively in your projects. The visual nature of construction work makes drawing comparisons particularly valuable for maintaining project integrity and communication flow.

Procore's comparison tool highlights changes in an intuitive color scheme that makes differences immediately apparent. Removed elements appear in red while added elements show up in blue, allowing you to quickly scan for modifications without getting lost in the details. This visual differentiation helps teams process changes more efficiently than traditional side-by-side comparisons.

Early identification of discrepancies through regular drawing comparisons can significantly reduce costly rework. When field teams have clear visibility into design changes, they can adjust their work accordingly before materials are ordered or installations begin. This proactive approach to change management keeps projects on schedule and within budget.

Streamlined communication is another major benefit of Procore's drawing comparison feature. When all stakeholders can view the same highlighted changes, discussions become more focused and productive. Instead of debating what has changed, teams can concentrate on how to address those changes effectively.

Getting Started with Comparisons

Before diving into drawing comparisons, you'll need to ensure you have the proper setup in your Procore environment. Taking care of these prerequisites will save you time and frustration when you're ready to start comparing drawings.

To use Procore's comparison feature, you need at least "Read Only" permissions in the project's Drawings tool. Without sufficient permissions, you won't be able to access or utilize the comparison functionality. Check with your project administrator if you're unsure about your current permission level.

The drawing you want to compare must have multiple revisions uploaded to Procore. If you're working with a new drawing that doesn't have previous versions, you'll need to upload at least one revision before you can use the comparison tool. Procore's Optical Character Recognition (OCR) technology automatically scans and processes these drawings to make comparisons more accurate.

File format consistency is crucial for successful comparisons. Drawings must be of similar dimensions to be properly compared. If you attempt to compare PDF files with significantly different dimensions, the tool may not align them correctly, resulting in misleading comparison results.

Desktop Comparison Process

Comparing drawings on your desktop provides a comprehensive view of changes between revisions. The larger screen real estate makes it easier to spot subtle differences that might be missed on mobile devices.

To begin comparing drawings on desktop, log into your Procore account and navigate to your project's Drawings tool. From the drawings list, locate the specific drawing you need to compare and click on the "Info" button next to it. This will open the drawing details page where you can access all available versions of that drawing.

Within the Versions section, you'll see a chronological list of all revisions that have been uploaded for this drawing. To initiate a comparison, click the vertical ellipsis icon next to your chosen revision and select "Compare to this version." This action launches the comparison view where both drawing versions are overlaid with color-coded highlights showing the differences.

The comparison view uses a consistent color scheme to indicate changes: red highlights show elements that have been removed, while blue highlights indicate new additions. You can toggle between different view modes to better visualize these changes according to your preferences. If you need to share or save this comparison, use the Download button to create a PNG file of the current view.

Analyzing Drawing Changes

Once you've initiated a comparison, understanding how to interpret the results is key to making informed decisions. The visual indicators in Procore's comparison tool provide valuable insights into the nature and extent of changes between drawing revisions.

When examining a drawing comparison, focus first on the areas with the most concentrated color highlights. These regions typically represent significant changes that warrant careful attention. Take your time to understand not just what has changed, but how these changes might impact other aspects of the project such as scheduling, materials, or coordination with other trades.

Beyond the red and blue highlights, pay attention to areas where both colors overlap. These overlapping highlights often indicate elements that have been moved or modified rather than simply added or removed. Understanding these nuances helps you gain a more complete picture of the design evolution between revisions.

After identifying the changes, consider documenting your observations directly within Procore. You can add comments or annotations to specific areas of the drawing to communicate concerns or questions to other team members. This integrated approach keeps all project-related discussions in one place for easier reference and follow-up.

Bulk Comparison Capabilities

For projects with numerous drawings, reviewing each one individually can be time-consuming. Procore's bulk comparison feature streamlines this process by allowing you to compare multiple drawings simultaneously.

To use the bulk comparison feature, navigate to the Drawing Sets option within the Drawings tool. Select the drawing set containing the drawings you want to compare, then click the "Compare Set" button. Procore will generate a comprehensive PDF document showing side-by-side comparisons of each drawing with its previous revision, highlighting changes in the same red and blue color scheme used in individual comparisons.

This generated PDF is automatically emailed to you, creating a permanent record of all drawing changes across the set. Having this documentation can be invaluable for project records, team meetings, or addressing questions that arise later in the project. The PDF format also makes it easy to share with team members who may not have direct access to Procore.

Bulk comparisons are particularly valuable during major design updates when numerous drawings receive revisions simultaneously. Rather than tracking each change manually, you can quickly identify which drawings have undergone significant modifications and prioritize your review efforts accordingly. This efficiency helps maintain project momentum even during periods of substantial design evolution.

The following situations make bulk comparisons especially useful:

• When receiving a new drawing package from designers
• During milestone reviews of project documentation
• Before important construction phases begin
• When onboarding new team members who need to understand project evolution

Mobile Comparison Techniques

Construction professionals often need to review drawings while on the job site. Procore's mobile applications for iOS and Android provide robust drawing comparison capabilities that match the desktop experience.

To compare drawings on your mobile device, open the Procore app and navigate to your project's Drawings tool. Select the drawing you wish to compare, then tap the "Compare Drawings" button. By default, the app will display a comparison between the two most recent revisions, using the same red and blue highlighting system as the desktop version.

Mobile comparison offers unique advantages for field teams. You can verify design changes while standing in the actual construction area, making it easier to visualize how modifications will impact the physical space. This immediate context helps identify potential conflicts before they become problems during construction.

One powerful feature available exclusively on mobile devices is the realignment tool. If your drawing comparisons appear misaligned, tap the "Comparing this drawing" header and select "Realign." This opens an interface where you can manually adjust the positioning of the drawings to achieve proper alignment. Once satisfied with the alignment, tap "Done" to apply your adjustments and continue reviewing the comparison.

Troubleshooting Common Issues

Even with Procore's intuitive design, you may occasionally encounter challenges when comparing drawings. Understanding how to address these issues can help you maintain productivity and ensure accurate comparisons.

Misalignment problems are among the most common issues users face. If your comparison view shows every element highlighted in both red and blue, the drawings are likely misaligned. On mobile devices, use the realignment feature to manually adjust the positioning. For desktop users, consider switching to the Windows 10 app which offers similar realignment capabilities, or contact Procore support for assistance with persistent alignment problems.

Permission-related errors can prevent access to comparison features. If you receive error messages or cannot initiate comparisons, verify that your account has at least "Read Only" permissions for the Drawings tool. Your project administrator can adjust these permissions if necessary. Remember that permission levels may vary between projects, so you might have comparison access in one project but not another.

File format inconsistencies sometimes cause comparison failures. Procore works best with PDF files (version 1.6 or later) of consistent dimensions. If your comparison isn't working as expected, check that both drawing versions have similar dimensions and are saved in compatible formats. Re-uploading problematic files often resolves these issues.

Enhancing Team Collaboration

Drawing comparisons serve as powerful collaboration tools when used effectively across your project team. The shared visual reference creates a common understanding that reduces misinterpretations and miscommunications.

Regular review sessions using Procore's comparison tool can bring team members together around concrete visual evidence of project evolution. Schedule brief meetings after significant drawing revisions to walk through the changes as a group. These collaborative reviews ensure everyone understands not just what has changed, but why those changes were made and how they affect different aspects of the project.

Procore's platform allows you to integrate drawing comparisons with other project documentation. You can link Request for Information (RFI) responses, submittals, and even photos directly to specific areas of compared drawings. This connected approach creates a comprehensive record of decision-making that provides valuable context for current team members and serves as an onboarding resource for new additions to the project.

Teaching team members to use comparison features effectively multiplies their value across your organization. Consider developing simple training materials or hosting short demonstration sessions to ensure everyone knows how to access and interpret drawing comparisons. When the entire team leverages these tools consistently, communication improves and errors decrease.

Best Practices for Drawing Management

Developing a systematic approach to drawing management and comparisons can significantly enhance your team's efficiency and accuracy. Implementing these best practices will help you maximize the benefits of Procore's comparison tools.

Establish a regular schedule for reviewing drawing revisions to ensure changes are identified promptly. Many successful teams incorporate drawing reviews into their weekly workflow, setting aside dedicated time to process new revisions and communicate relevant changes to field personnel. This consistent approach prevents important updates from being overlooked during busy periods.

Document your comparison findings to create a historical record of drawing evolution. After completing important comparisons, consider downloading the highlighted comparison view and adding brief notes about significant changes. Store these annotated comparisons in a designated location within Procore for easy reference throughout the project lifecycle.

When working with complex drawings, focus your comparison efforts strategically. Begin by examining critical areas such as structural elements, MEP (Mechanical, Electrical, Plumbing) systems, and architectural features that affect multiple trades. This prioritized approach ensures the most consequential changes receive appropriate attention even when time is limited.

Real-World Application Examples

Drawing comparisons prove their value in numerous real-world scenarios. Understanding these practical applications can help you identify opportunities to leverage comparison tools in your own projects.

On a recent commercial construction project, the project manager received revised structural drawings midway through foundation work. Using Procore's comparison tool, she immediately identified changes to several column locations that would have affected ongoing concrete placements. By spotting these modifications early, the team adjusted their forms before pouring, avoiding costly rework that would have impacted both budget and schedule.

A healthcare renovation project involved complex phasing to maintain hospital operations during construction. The superintendent used bulk drawing comparisons to review each new drawing package, focusing particularly on temporary partition locations and access routes. This systematic review process ensured that construction activities never compromised patient safety or critical hospital functions.

During a multi-building campus project, subcontractors used mobile drawing comparisons to verify design details while working in the field. When questions arose about recent changes to mechanical systems, the HVAC foreman pulled up the drawing comparison on his tablet and confirmed the new requirements without leaving the installation area. This immediate access to accurate information prevented installation errors and eliminated delays that would have occurred if the team had needed to return to the job trailer to check paper drawings.

Optimizing Your Workflow

Integrating drawing comparisons into your regular workflow maximizes their benefit while minimizing disruption to your existing processes. With thoughtful implementation, these tools enhance rather than complicate your project management approach.

Create a standardized process for handling new drawing revisions that includes comparison as a key step. When new drawings arrive, designate specific team members to perform comparisons and distribute findings to relevant stakeholders. This systematic approach ensures that important changes don't slip through the cracks during busy project phases.

Consider how drawing comparisons interact with other project documentation systems. Many teams create direct links between identified drawing changes and related documentation such as RFIs, change orders, or submittals. This integrated approach provides valuable context for understanding why changes occurred and how they've been addressed throughout the project lifecycle.

Take advantage of Procore's notification features to alert team members about new drawing revisions. Configure your settings to automatically notify relevant personnel when drawings in their area of responsibility receive updates. These timely alerts prompt immediate review of changes, reducing the risk that team members will work from outdated information.

The most effective comparison workflows incorporate feedback loops that verify changes have been properly implemented. After identifying and communicating drawing revisions, schedule field verifications to confirm that construction activities reflect the updated requirements. This verification step closes the loop on the change management process and prevents discrepancies between design and construction.

Mastering Procore Drawing Tools

Drawing comparisons represent just one component of Procore's comprehensive drawing management system. Understanding how this feature connects with other drawing tools can enhance your overall project documentation strategy.

Procore's markup capabilities complement the comparison feature by allowing you to annotate identified changes. After comparing drawings, use the markup tools to add notes, dimensions, or clarifications directly on the drawing. These annotations help communicate specific concerns or instructions related to the changes, providing valuable context for team members reviewing the documentation.

The platform's version control system works hand-in-hand with comparison tools to maintain a complete history of drawing evolution. Each time you upload a new revision, Procore preserves previous versions and makes them available for future reference or comparison. This comprehensive version history creates an audit trail that documents the progression of design development throughout the project lifecycle.

Procore's mobile synchronization ensures that drawing comparisons remain accessible even in areas with limited connectivity. The application automatically downloads drawing data to your mobile device, allowing you to perform comparisons and review changes regardless of internet availability. When connectivity returns, any notes or markups you've added will synchronize with the central project database.
