DEMOLITION TURBIDITY CONTROL

2016-2017

Challenges:

• Turbidity NTE 30% increase

• Deep water, significant currents

• Buried obstructions precluded sheet pile

• Silt curtain not effective enough

• Pressing project schedule

Solutions:

• Bottom-sealing filter barriers

• Designed to perform for the 6-month project schedule, allowing for cost-saving design elements

• Responsive to schedule needs

Outcome:

• No project exceedances

• In-water maintenance allowed performance to continue for an unplanned extension from 6 to 18 months

• Bulky underwater debris complications addressed without compromise in performance
