Navigating the Shop Drawing Review Process

Reviewing shop drawings is a critical step in commercial glazing projects. It ensures that the design intent matches the actual fabrication and installation requirements. Mistakes or oversights in this phase can lead to costly delays and rework. I will guide you through the essentials of reviewing shop drawings efficiently and accurately.


Understanding the Importance of Reviewing Shop Drawings


Shop drawings provide detailed information about the components to be fabricated and installed. They translate architectural and engineering designs into practical instructions for manufacturers and installers. Reviewing these drawings carefully helps catch errors early.


Focus on these key points when reviewing:


  • Verify dimensions against project specifications.

  • Check material types and finishes.

  • Confirm compliance with structural and safety standards.

  • Ensure coordination with other trades and systems.


A thorough review reduces risks and improves project outcomes. It also supports clear communication between contractors, fabricators, and designers.

Best Practices for Reviewing Shop Drawings


Approach the review process methodically. Use a checklist to cover all critical aspects. Here is a practical workflow:


  1. Initial Review

    Scan the entire drawing set to get an overview. Identify any missing sheets or unclear notes.


  2. Dimension Verification

    Measure all critical dimensions. Cross-check with architectural plans and field measurements.


  3. Material and Finish Confirmation

    Confirm that specified materials match project requirements. Look for any substitutions or deviations.


  4. Structural and Code Compliance

    Review engineering details. Ensure the design meets local building codes and safety regulations.


  5. Coordination Check

    Verify that the shop drawings align with other trades such as wall framing, steel, and concrete.


  6. Markups and Comments

    Use clear, concise notes to communicate required changes or approvals.


  7. Final Approval

    Once all issues are resolved, sign off on the drawings to proceed with fabrication.


Use digital tools when possible to streamline the process and maintain accurate records.


How to review window shop drawings?


Window shop drawings require special attention due to their complexity and impact on building performance. Here’s how to handle them:


  • Check Frame Dimensions

Confirm that frame sizes match the openings on the architectural plans and field measurements.


  • Verify Glass Specifications

Ensure glass type, thickness, and coatings meet project requirements for energy efficiency and safety.


  • Review Hardware Details

Look at hinges, locks, and other hardware for compatibility and functionality.


  • Assess Installation Details

Confirm flashing, sealants, and anchoring methods are clearly detailed to prevent water infiltration.


  • Coordinate with Structural Elements

Make sure window supports and reinforcements are properly designed.


  • Confirm Compliance

Check that windows meet local codes for wind loads, impact resistance, and egress requirements.


Pay close attention to notes and details. Any ambiguity can cause installation issues or performance failures.



Common Pitfalls to Avoid When Reviewing Shop Drawings


Avoid these frequent mistakes to keep projects on track:


  • Overlooking Small Details

Minor notes or symbols can have major implications. Don’t skip them.


  • Ignoring Field Conditions

Always compare drawings with actual site measurements. Conditions often vary.


  • Failing to Coordinate with Other Trades

Lack of coordination leads to clashes and delays.


  • Rushing the Review

Take the time needed to be thorough. Speed can compromise quality.


  • Not Documenting Changes Clearly

Use clear markups and maintain a log of revisions.


  • Assuming Fabricators Will Catch Errors

Responsibility lies with the reviewer to ensure accuracy.


Being vigilant and systematic prevents costly errors and rework.


Leveraging Technology in the Shop Drawing Review Process


Use technology to improve accuracy and efficiency. Digital tools offer many advantages:


  • PDF Markup Software

Annotate drawings directly. Share comments instantly.


  • Cloud Collaboration Platforms

Centralize communication and document control.


Integrating these tools supports a smoother shop drawing review process and better project outcomes.


Final Steps to Ensure a Successful Shop Drawing Review


After completing the review, follow these steps:


  • Compile all comments and corrections clearly.

  • Communicate feedback promptly to fabricators.

  • Confirm receipt and understanding of revisions.

  • Schedule follow-up reviews if necessary.

  • Keep detailed records of approvals and changes.

  • Monitor fabrication progress against approved drawings.


This disciplined approach helps maintain quality and keeps the project moving forward.



Mastering the review of shop drawings is essential for commercial glazing success. It demands attention to detail, coordination, and clear communication. Use the strategies outlined here to improve your process and deliver reliable results every time.
