Professional Review of Structural Steel Shop Drawings Before Fabrication
Structural steel shop drawings are one of the final opportunities to identify errors, omissions, coordination issues, and constructability concerns before fabrication begins.
Mistakes discovered in the shop, during delivery, or after erection can result in delays, change orders, fabrication costs, and field modifications that significantly impact project schedules.
Sepco Consulting Engineers provides structural steel shop drawing review services throughout Ontario for steel fabricators, contractors, developers, architects, engineers, and project owners.
We review shop drawings to help ensure that fabricated steel components accurately reflect the design intent and project requirements before production begins.
Why Shop Drawing Review Matters
Structural steel projects often involve numerous components, including beams, columns, braces, connections, plates, anchors, and miscellaneous steel elements.
Even minor errors can create significant challenges during fabrication and erection.
A professional review can help identify:
- Missing information
- Drawing inconsistencies
- Connection conflicts
- Coordination issues
- Constructability concerns
- Dimensional discrepancies
- Unsupported field assumptions
- Potential fabrication challenges
Identifying issues before fabrication is typically far less costly than correcting them in the field.
Shop Drawings We Review
We review a wide range of structural steel fabrication documents, including:
- Structural steel shop drawings
- Erection drawings
- Connection drawings
- Miscellaneous steel drawings
- Stair drawings
- Platform drawings
- Catwalk drawings
- Guardrail drawings
- Ladder drawings
- Equipment support drawings
- Temporary steel structure drawings
Reviews are performed based on the available design information, project requirements, and applicable engineering standards.
Structural Steel Connection Verification
Many projects include delegated connection design responsibilities or custom connection details.
Our review may include:
- Connection geometry review
- Connection load verification
- Bolt configuration review
- Weld review
- Plate sizing review
- Connection constructability review
- Coordination with design calculations
Where required, additional calculations can be provided to support the proposed connection details.
Support for Fabricators and Contractors
We frequently work directly with:
- Structural steel fabricators
- Miscellaneous metal fabricators
- General contractors
- Structural contractors
- Design-build teams
- Engineers of record
- Project owners
Our objective is to provide practical feedback that supports efficient fabrication and successful project execution.
Existing Design and Third-Party Reviews
In some cases, clients request an independent review of shop drawings prepared by others.
These reviews may be beneficial when:
- Complex structures are involved
- Significant project costs are at stake
- Multiple parties are coordinating fabrication
- Existing conditions create uncertainty
- Additional quality assurance is desired
An independent engineering review can help identify potential issues before fabrication proceeds.
What We Provide
Depending on project requirements, services may include:
- Shop drawing review
- Engineering comments
- Connection verification
- Structural calculations
- Design clarification
- Engineering letters
- Stamped engineering documentation
- Peer review services
Our reviews are focused on helping clients reduce risk and improve project execution.
