April 2024
Project Summary
Challenge
Aging grooved piping, valves, and fittings compromised system reliability and required phased replacements under strict facility shutdown constraints.
Our Approach
We upgraded the entire system with new copper and press fittings, installed new circulation pumps, and replaced insulation—all while adhering to controlled shutdown windows.
Project Highlights:
- Completed complex replacements with a 72-hour shutdown limit per phase.
- Carefully staged and executed work to maintain system functionality.
- Expanded project scope to include coil replacements and additional piping.
- Aligned with DOC’s operational needs to minimize disruptions.
