  1. Compendium of Pile Driving Sound Data James Reyff Illingworth & Rodkin, Inc 2006 Summer Meeting TRB ACD40 Williamsburg, VA

  2. Purpose for the Compendium • Document Available Underwater Pile Driving Sound Levels • Provide data for biological assessments • Provide data for Construction/Design Decisions

  3. What is the Compendium? Provides Underwater Sound Data for • Different Types of Piles • Different Types of Installations • Different Conditions (unattenuated, attenuated, etc…)

  4. Different Types of Piles

  5. Different Types of Hammers 3,000 lb Drop Vibratory

  6. Different Types of Hammers Diesel Impact Hydraulic Impact

  7. Different Types of Hammers Large Hydraulic

  8. Different Types of Conditions Unattenuated Air Bubble Curtain

  9. Different Types of Conditions Air Bubble Curtain

  10. Different Types of Conditions Dewatered Casing

  11. Different Types of Conditions Dewatered Casing

  12. Different Types of Conditions Dewatered Cofferdam

  13. Different Types of Conditions Dewatered Cofferdam

  14. Different Types of Conditions On Land Near Water

  15. Tabular Summary of Measured Sound Levels

  16. Compendium Chapter Contents Divided by Pile Type & Project • Pile Size • Hammer Type Includes -Project Type/Location -Measured sound pressures at different distances -Measured drop-off rate -Effectiveness of attenuation systems -Signal analysis

  17. Example Chapter – Benicia Bridge

  18. Table 3.2-1 Summary of Unattenuated Sound Pressures Measured for the Benicia-Martinez Bridge Approximate Distance1 Sound Pressure Peak RMS SEL 5 m 227 215 201 10 m 220 205 194 20 m 214 203 190 50 m 210 196 184 100 m 204 192 180 500 m 188 174 164 1,000 m 180 165 155 1 Measured from the pile at about mid depth (10-15-m deep water) Summary of Unattenuated Sound Pressure Over Distance

  19. Graphical Representation of Sound Pressure with Distance Peak = 218 – 15 log (R/10) RMS = 206 – 16 log (R/10) SEL = 195 – 17 log (R/10)

  20. Attenuation Systems

Steel

  22. Representative Signal Analysis

  23. Compendium - I&R Projects • 8 Large dia. CISS Piles (Big Projects) • 10+ small to medium dia. Steel Pipe • 7-8 concrete piles • ~5 Steel “H” piles • 1 Steel sheet (vibratory and impact) • 1 Timber pile (small drop hammer) • ~5 Projects w/Vibratory hammers

  24. Compendium - Other Projects • NOAA Southwestern Division • Washington DOT • Other misc. projects

  25. That’s it….
