Shop Drawings
Facade shop drawings play an important role in a construction project. They turn design ideas into clear details for fabrication and installation. A good review can help find problems before they reach the site.
But how should a consultant review facade shop drawings?
A proper review should cover more than dimensions. It should also check materials, connections, structural support, waterproofing, coordination, fabrication, and installation.
In this guide, we share a simple consultant checklist for reviewing facade shop drawings. It can help architects, consultants, contractors, and facade teams review drawings with greater confidence.
What Are Facade Shop Drawings?
Facade shop drawings are detailed technical drawings used to manufacture and install facade components.
They can include:
- Curtain wall systems
- Storefront systems
- Windows and doors
- Glass systems
- Aluminum panels
- ACP cladding
- Stone cladding
- Metal panels
- Louvers
- Canopies
- Flashings
- Facade connections
The drawings provide information that may not appear in the architectural drawings.
They can show dimensions, materials, profiles, connections, fixing points, glass types, finishes, joints, and installation details.
For projects that need professional shop drawing services, accurate drawings can make fabrication and installation much easier.
Why Is a Facade Shop Drawing Review Important?
A facade has many parts that must work together. A small mistake in one detail can cause problems during fabrication or installation.
For this reason, consultants should review the drawings before fabrication begins.
A good review can help:
- Confirm design intent
- Check dimensions
- Verify materials
- Review connections
- Confirm structural support
- Check waterproofing
- Review movement joints
- Coordinate different trades
- Find possible clashes
- Reduce site changes
- Improve installation accuracy
Early review can save both time and money.
Consultant Checklist for Facade Shop Drawings
1. Check the Drawing Information
Start with the basic drawing details.
Check the:
- Project name
- Drawing number
- Drawing title
- Revision number
- Date
- Drawing status
- Scale
- Prepared by
- Checked by
Make sure you are reviewing the latest revision.
This is important because an old drawing can contain information that is no longer valid.
Also check whether the drawing is marked For Approval, For Construction, or For Fabrication.
2. Compare the Shop Drawing With the Design
The shop drawing should follow the approved design.
Compare the drawing with the latest architectural information.
Check:
- Facade shape
- Floor levels
- Grid lines
- Openings
- Mullion positions
- Panel sizes
- Window locations
- Door locations
- Architectural features
If something is different, find out why.
Some changes may be needed for fabrication or engineering. However, major changes should be reviewed and approved by the right project team.
3. Check All Important Dimensions
Dimensions are one of the most important parts of a shop drawing.
Check:
- Overall width and height
- Floor-to-floor dimensions
- Opening sizes
- Mullion spacing
- Transom positions
- Panel sizes
- Glass sizes
- Joint widths
- Edge distances
- Tolerances
Compare these dimensions with the architectural and structural drawings.
Also check the plans, elevations, and sections.
The same component should have matching dimensions in all related views.
4. Review the Facade Setting Out
The facade must line up correctly with the building structure.
Check the relationship between:
- Structural grids
- Architectural grids
- Floor slabs
- Columns
- Beams
- Mullions
- Windows
- Panel joints
Pay close attention to slab edges and structural movement.
Good setting out helps avoid problems during installation.
5. Check Materials and Specifications
Every major facade material should be clearly identified.
Review:
- Aluminum
- Glass
- Steel
- Sealants
- Gaskets
- Insulation
- Membranes
- Cladding
- Fasteners
- Brackets
- Anchors
- Finishes
Compare these details with the project specification and approved materials.
For glass, check the type, thickness, coating, and performance requirements.
For cladding, check the material thickness, finish, joints, and fixing method.
6. Review Mullions and Transoms
For curtain wall and storefront projects, mullions and transoms need special attention.
Check:
- Profile sizes
- Profile shapes
- Mullion locations
- Transom locations
- Thermal breaks
- Gaskets
- Pressure plates
- Cover caps
- Drainage paths
The selected profiles should suit the required glass, panels, seals, and accessories.
For more information, see our guide to Curtain Wall Systems.
7. Check Structural Connections
Connections are critical to facade performance.
Review:
- Brackets
- Anchors
- Bolts
- Screws
- Plates
- Reinforcement
- Welds
- Embedments
- Fixing points
Check how the facade connects to the building structure.
The drawing should clearly show how loads are transferred from the facade to the building.
Where required, confirm that structural calculations support the proposed connection.
8. Review Wind Load Requirements
Facades are exposed to wind pressure.
The consultant should check that the shop drawing follows the approved design requirements.
Review:
- Wind pressure
- Mullion spans
- Glass spans
- Panel spans
- Anchor locations
- Bracket spacing
- Structural support
The shop drawing may not include all engineering calculations.
However, the drawing should be consistent with the approved engineering design.
9. Check Movement and Tolerances
Buildings move over time.
Facade systems must allow for movement caused by:
- Thermal expansion
- Structural deflection
- Wind
- Seismic movement
- Construction tolerances
Check movement joints and connection details.
Also review how the facade handles slab deflection.
If movement is not properly allowed for, it can lead to cracks, glass damage, sealant failure, or other problems.
10. Review Waterproofing and Drainage
Water management is a major part of facade design.
Check:
- Flashings
- Weep holes
- Drainage paths
- Sill details
- Head details
- Jamb details
- Membranes
- Sealant joints
- End dams
Ask one simple question:
If water enters the facade system, where will it go?
The drawing should provide a clear drainage path.
This is especially important where two different facade systems meet.
11. Check Sealants and Joints
Sealants help control water and air movement.
Review:
- Sealant type
- Joint width
- Joint depth
- Backer rods
- Bond breakers
- Substrate conditions
- Sealant locations
Make sure the joints are practical for installation.
Also check whether movement joints are correctly detailed.
12. Review Glass Details
Glass is a major component of many facade systems.
Check:
- Glass type
- Glass thickness
- Number of panes
- Low-E coating
- Tempering
- Heat strengthening
- Laminated glass
- Spacer
- Interlayer
- Edge conditions
Also check the glass dimensions and support conditions.
The glass information should match the approved project requirements.
13. Check Thermal Details
A well-designed facade should help control heat and moisture.
Review:
- Thermal breaks
- Insulation
- Spandrel insulation
- Air barriers
- Vapor control
- Thermal bridges
- Condensation risks
Pay special attention to areas where aluminum, steel, glass, and concrete meet.
These areas can create thermal bridges if they are not properly detailed.
14. Review Other Building Interfaces
Facade drawings should not be reviewed on their own.
Compare them with:
- Architectural drawings
- Structural drawings
- Waterproofing drawings
- Roofing drawings
- MEP drawings
- Interior drawings
- Door schedules
- Window schedules
- Fire-stopping details
Pay special attention to slabs, roofs, parapets, doors, windows, and internal partitions.
Good coordination can prevent expensive changes on site.
15. Check Fire Safety Details
Where required, review the fire safety details of the facade.
Check:
- Fire stops
- Cavity barriers
- Spandrel protection
- Fire-rated interfaces
- Compartmentation
- Fire-resistant materials
The exact requirements depend on the project and local building codes.
Always compare the drawings with the approved fire strategy and project requirements.
16. Review Fabrication Details
A shop drawing must be practical for manufacturing.
Check:
- Profile lengths
- Cutting dimensions
- Machining
- Drilling
- Notches
- Slots
- Assembly details
- Fasteners
- Accessories
- Tolerances
Ask whether the components can be manufactured as shown.
A drawing can look correct but still contain details that are difficult to fabricate.
For detailed drafting support, see CJFacade’s Drafting and Shop Drawing Services.
17. Check Installation Details
The drawing should also provide enough information for installation.
Review:
- Fixing methods
- Bracket installation
- Temporary supports
- Sealant application
- Glass installation
- Panel installation
- Adjustment points
- Installation sequence
The details should be practical for the site team.
If the installation method affects the design, it should be clearly shown.
18. Review BIM Coordination
BIM can make facade coordination easier.
A coordinated model can help identify clashes between the facade and:
- Structural elements
- MEP services
- Interior systems
- Waterproofing
- Roof systems
- Other facade components
BIM coordination can find problems before fabrication begins.
You can also learn more about the role of BIM in our guide, Introduction to Modern Facade Engineering.
19. Check Drawing Consistency
Now review the complete drawing package.
Compare:
- Plans
- Elevations
- Sections
- Details
- Schedules
- Material lists
- Connection details
Make sure the same component has the same reference and specification throughout the package.
For example, a mullion shown in an elevation should match the related section and detail.
20. Check Previous Comments
Finally, review all previous consultant comments.
Check whether:
- Previous comments have been addressed
- Revised details are included
- Changes are clearly marked
- Responses are provided
- References are updated
- Open issues are listed
Do not close a comment simply because the drawing has changed.
Check that the original issue has actually been resolved.
