• Exploratory work along St. Clair• Property surveys (Mainly along E.
109th)• Utility relocation, site prep• Start work on mainline sewer
structures along E. 110th/Hazeldell• Sheet pile and secant pile
construction
Sheet piling
• Traditional method• Vibratory hammer creates noise,
vibration• Sheeting extends above ground• Used where space is limited
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
