Engineering Support for Manufacturers: FAQ
This page explains how engineering support works for manufacturers, what is included in production engineering, and when additional engineering support is required. The goal is to keep projects moving efficiently while maintaining clear responsibility boundaries.
What Engineering Support Is Included for Manufacturers?
Most manufacturing projects are supported through production engineering, which is designed for repeatable systems and consistent deployment.
Production engineering typically includes:
Engineering based on the approved architectural and system drawings
Code-required calculations for the defined system
Permit-ready engineering documents
Responses to plan review comments related to the submitted design
Clarifications of the engineering intent shown in the drawings
This level of support is sufficient for the majority of standard kit, panel, or system deployments.
What Is Not Included in Production Engineering?
Production engineering does not include open-ended consulting or redesign.
Items not included unless specifically contracted:
Redesign of layouts or system geometry
Alternative system exploration or value engineering
Field condition interpretation
Construction means, methods, or sequencing
Installation troubleshooting not reflected in the plans
Cost optimization or product substitution analysis
These services require additional engineering time and responsibility.
What Is the Difference Between Clarification and Interpretation?
This distinction is critical for manufacturers.
Clarification
Explains what is already shown or specified in the approved engineering documents.
Examples:
- • Responding to AHJ questions
- • Confirming details already shown on the plans
- • Referencing code sections or notes
Clarifications are included in production engineering.
Interpretation
Applies engineering judgment to conditions that differ from the approved design.
Examples:
- • Changes to materials or products
- • Site conditions that differ from assumptions
- • Adjustments needed to "make it work" in the field
Interpretations typically require additional engineering support.
When Is Principal Engineering Required?
Manufacturers typically require principal engineering when:
A standard kit or system is modified
Architectural inputs change after engineering has begun
A project requires non-standard detailing
Multiple changes occur across a project or portfolio
Engineering judgment is needed beyond the approved documents
Principal engineering provides advisory support and direct access to the principal engineer.
Quick Reference for Manufacturers
Standard kit, no changes → Production Engineering
Modified kit or system → Principal Engineering
Design change after issuance → Change Order
If you're unsure how a request should be handled, contact your project coordinator and it will be routed appropriately.
