MethodsEarth retention system
Michels Construction, Inc. designed and installed a 500-linear-foot sheet pile wall with three levels of tieback anchors for a permanent earth retention system. This earth retention system allowed the construction of parking structure for Children's Hospital. A temporary earth retention system comprised of H-pile/ wood lagging, sheet pile and tiebacks was designed and constructed to facilitate the construction of a mechanical room.
Sheet pile was installed with an ABI machine and ABI vibratory hammer. Prior to the sheeting installation, Michels used the ABI with a pre-drill attachment to pre-drill the sheet pile wall at each interlock location. Three Klemms were used to install the tiebacks.
