Preventing Miswire Before Mobilization: How Engineering Validation Averted Station Service Errors in West Virginia
The Challenge
The Solution
- Conducted a comparative review of the construction drawings and one-line diagrams
- Identified and flagged the inconsistencies
- Collaborated with the engineering team to resolve the conflict by relocating the station service to a different bay and confirming a verified connection to bus #1
- Documented the resolution and ensured the updated prints were distributed to all field teams
Key Benefits
- Risk Elimination: Prevented incorrect station service connections that could have jeopardized energization sequencing or introduced safety hazards
- Improved Cross-Team Alignment: Bridged the communication gap between field operations and design engineering teams amid staff turnover
- Change Management: Successfully adjusted scope in response to outdated or contradictory documentation
- Engineering QA/QC Enforcement: Reinforced the need for real-time drawing validation before executing critical connections
- Delay Mitigation: By resolving the issue early in the cycle, avoided the risk of further field delays or system rework
The Results
- No rework or misinstallation occurred due to the detected conflict
- Updated construction prints were redistributed, ensuring alignment across field and engineering teams
- The case underscored the value of conducting pre-mobilization design reviews, especially on projects with high turnover
- It reinforced a repeatable process for identifying and resolving documentation mismatches before they impact the field
