• Sheet pile and secant pile construction

17. Sheet piling
• Traditional method
• Vibratory hammer creates noise, vibration
• Sheeting extends above ground
• Used where space is limited

18. Secant Pile Construction
 Alternative method for
supporting excavations
 Holes are drilled with an auger
and then filled with concrete
 Requires slightly larger
footprint than sheet piling
 Installed flush with the surface
 Drilling operation creates
vibration noise
