Jennings Randolph Dam and Lake (originally Bloomington Dam and Lake) is a major multipurpose water resources project operated by the U.S. Army Corps of Engineers (USACE) Baltimore District.
As a major subcontractor on the Jennings Randolph Tainter Gate rehabilitation project, Paragon faced a highly complex and demanding scope of work involving five Tainter gates in an active dam environment:
• Installation of a SSPC Class 1A containment and ventilation system
• Abrasive blasting and painting of five 32-ft-high x 42-ft-wide Tainter gates.
• Pre-blasting all welds to allow for complete weld inspection and third-party NDT evaluation.
• Application of the USACE-specified 5EZ vinyl coating system over the entire gate surfaces.
• Installation of temporary gate supports during the rehabilitation process.
• Strict environmental controls required for the safe removal of the existing coating system.
• Working in a confined, high-risk dam setting where gates must remain ready for immediate operation.
Paragon self-performed the critical containment, abrasive blasting, and painting scopes with precision and reliability.
To address the challenges of paint removal in an active Tainter gate environment, Paragon designed and erected an SSPC Class 1A containment system that fully captured all spent abrasive and paint debris while maintaining strict environmental compliance.
This smart, streamlined anchoring approach significantly reduced impact on the existing concrete while improving safety and efficiency. Paragon’s innovative containment and rapid demobilization methods further lowered project risk in this complex, marine environment.
