September 2013 to October 2014 December 2013 to November 2014 Silent Piler GV-ECO1400S Silent Piler GV-ECO1400S AZ25 & AZ19, L=35' & 54', N=1316 pairs PZC19 L=35' The Press-in Method was specified by the Orange County Public Works Department in California to install a sheet pile wall in order to effectively minimize the chance of levee breaches due to flooding and erosion. Due to the hard ground conditions along the channel, the Crush Auger System was required to install the sheets within limited space. The Press-in Pile Driving Method was specified by the City of Ventura Watershed Protection District in California to minimize noise & vibration impacts to adjacent apartments & homes while installing a retaining wall system. An existing sewer line located just 12 inches away from the sheet pile line was another reason for the specification of the Press-in Method. 3 4

Toronto, CANADA Zefiro Corporation Go Transit April 2015 to August 2015 West Diamond Joint Venture SCZ675SMG, UP150 PZC18, L=25' & SX27, L=25' 17 September 2009 to September 2010 Tubular Piler SCP260 d=914.1mm, PT Interlock, t=12.7 & 19.1mm, L= m, N=522 pairs No negative impact to neighbors and near the commercial facility. Sheet piling work at the silt layer with gravel with SPT N-value over 160. Safety piling work without disturbing active railway service. There is the adjacent building 2 meters from the press-in line. N-value over 50 is converted figure. The Press-in Pile Driving Method was utilized for this emergency bridge pier repair on the Scioto River in Columbus, OH since conventional pile driving equipment may have caused more damage to the actively sinking bridge pier. In addition, the smallest Giken Silent Piler in the U.S. was used for this project due to the project s limited vertical clearance. Piling work proceeded on a 24-hour basis due to the Silent Piler s non-vibratory and minimal noise characteristics. The Silent Piler s power pack was able to elude the river s increasing and decreasing water levels during its 24-hour operation since the power pack is remote-controlled and equipped with a crawler. 18

11 Theme Park Causeway in Orlando Sheet Pile Installation 17 Sheet Pile Installation Completion Theme Park Causeway Stormwater Retention Theme Park in Orlando, FL PCL Construction Services, Inc. Blue Iron Foundations and Shoring, LLC February 2014 to April 2014 Silent Piler GV-ECO1400S AZ26-700, L=45' The Press-in Pile Driving Method was utilized to install a steel sheet pile cofferdam in Orlando, FL with a Giken Silent Piler press-in pile driver in order to minimize noise & vibration impacts for the theme park visitors. Due to its accurate functions, the Silent Piler was also used to overcome very tight pile line tolerances on the project site since pre-cast concrete panels were to be installed after sheet pile installation was complete. The entire length of this causeway was designed based on a predetermined radius. The pressed-in sheet piles were designed to carry the entire bridge load. 20

Sheet pile driving was necessary for the emergency project. However, due to the risk of a secondary disaster occurring at an adjacent building by using a vibratory hammer, the Silent Piler was chosen to press in the sheet piles. Due to heavy rain, a storm drain culvert collapsed, resulting in the above ground to collapse as well. In consideration of the risk of a secondary disaster occurring at an adjacent building by using a vibratory hammer, the Silent Piler was chosen to press in the sheet piles
