Review of an 18-sheet electrical wiring and schematic package (Rev. 6)
Resolution of three open reviewer comments
Markup and redline guidance
Written summary of findings
Summary
A manufacturer of prefabricated substation control enclosures asked MHL to close out the last three review comments on its Rev. 6 electrical package before resubmittal to the project reviewer. MHL reviewed the AC and DC power, alarm, lighting, ventilation and device wiring sheets and returned markups.
Problem / Objective
Three comments remained open on a tight schedule: separating the exterior lighting circuit from a shared breaker, integrating an HVAC lead-lag controller, and correcting the rating of the HVAC high/low temperature alarm thermostat.
Process
Reviewed the full Rev. 6 package (Sheets 1 to 18) against the earlier Rev. 5 markups and the comment email.
Sent specification questions on the controller and exterior lighting switching.
Analyzed the three open comments across the affected sheets.
Returned redlines and a short written summary with drafting feedback.
Held a final comments call and confirmed all three comments closed.
Payoff / Results (Metrics)
All three open comments confirmed closed
Completed within the client’s tight timeline
Led to follow-on as-built documentation work on the same enclosure
When this applies
A manufacturer of prefabricated enclosures, E-houses or relay panels who needs an independent PE to review wiring and schematic drawings and close review comments before shipping to a utility-scale solar or substation project.
