Key takeaways
- Shop drawings communicate fabrication or installation information; they do not automatically constitute engineering design.
- Delegated-design criteria and responsibility should be defined in the contract documents.
- The specialty engineer needs governing design criteria, loads, interfaces, and current documents.
Shop drawings versus design documents
Shop drawings typically show how a contractor, fabricator, or supplier proposes to manufacture or install part of the work. Some submittals also contain delegated engineering, such as connection design, component supports, specialty structures, or manufacturer-engineered systems.
Whether a professional seal is required depends on the delegated scope, contract documents, jurisdiction, and applicable professional-practice rules.
Information a specialty engineer needs
- Current governing drawings and specifications
- Clearly identified delegated-design criteria
- Applicable loads, reactions, movements, and environmental conditions
- Material, fabrication, installation, and interface requirements
- Review comments and revision history
Avoid responsibility gaps
Clarify who designs the component, who designs supporting construction, who supplies loads or reactions, and who checks interfaces. A sealed specialty calculation does not automatically cover adjacent systems or field installation outside the stated scope.
Frequently asked questions
Does the engineer of record stamp every shop drawing?
Not necessarily. Roles vary by contract and jurisdiction. The engineer of record may review submittals for general conformance while a specialty engineer seals delegated design within a defined scope.
Can fabrication begin before engineering comments are resolved?
That creates substantial risk. Follow the project's approved submittal and release process before fabrication or installation.
