THE SHORT ANSWER
DOE describes design reviews at schematic, full-draft and pre-final stages as a way to confirm severe-weather requirements are incorporated. [1]
Review the early concept
Confirm service address, utility, roof areas, equipment locations, capacity and known hazards before detailed engineering. List assumptions that require site verification.
Review the full draft
Trace structural load paths, attachment zones, wire management, enclosures, clearances, shutdown, storage and permit notes. Compare every equipment model with the proposal.
Review the pre-final set
Close comments, verify calculations and freeze authorized substitutions. Mark the final owner-approved revision clearly so crews do not build from a superseded drawing. Confirm the installation team received it.
Keep the review history
Save comments, responses and approvers at each stage. The record helps explain field changes and supports later roof, warranty or maintenance work.
Before your next conversation
- Validate schematic assumptions.
- Audit the full draft.
- Freeze the pre-final design.
- Keep comments and approvals.
