Why Cut and Cap may still be the best option
• Ability to get at piles and inspect them
Look at pile, soil, and groundwater level
• Reliable permanent solution
Engineering assessment and design
Piles cut based on the lowest expected future GW levels
Steel Lally column encased in Concrete to maintain the “load path”, provide bracing, and prevent corrosion
Alternatives may or may not work we know (when properly engineered) cut and cap does work
