The project requires two shafts construction and 200ft open cut for installing 98" new sewer pipe by micro tunneling machine need to be installed at the location where is closed by existing old water pipe (Just 12" away) and residential apartment. In addition, there was difficult sub soil condition which consists of very dense gravel layer and high water table. The installing of temporary shaft using SCZ675WM with 200GPM discharge water jetting system was succeed completely without any disruption. The project for installing 90feet sheet pile using Press-in method was the longest length in any sheet pile driving history by vibration free method. The project is still under construction.

The temporary shafts for installing new sewer need to be installed at the location where is closed by existing old water pipe and public rail way. The clearance between the alignment and water line is only 12". In addition, there was limited space for the service crane due to the public railway closed. The installing of temporary cofferdam using UP150 Silent PIler which is the smallest machine in various Silent piler in USA, was succeed completely without any disruption. The project using Press-in method by Silent Piler was adapted at first time for City of Port Hueneme.

The project requires 6 shaft construction for installing 66" new sewer pipe by micro tunneling machine need to be installed at the location where is closed by existing old water pipe (Just 12" away). In addition, there was limited overhead clearance due to high voltage power line is crossed on shoring alignment. The installing of temporary shaft using UP150 with Pre-augering and water jetting method was succeed completely without any disruption. The project using Press-in method by UP150 Silent Piler was adapted at first time for Department of Water and Power. The project is still under construction.

The temporary cofferdam for installing new sewer need to be installed at the location where is closed by existing old water pipe. The clearance between the alignment and water line is only 10". In addition, there was limited access way for the service crane and difficult soil condition was encountered. The installing of temporary cofferdam using UP150 Silent Piler which is the smallest machine in various Silent Piler in USA, was succeed completely without any disruption. The project using Press-in method by Silent Piler was adapted at first time for City of Los Angeles.

The temporary cofferdam by sheet pile driven for cut of water need to be removed at the location where is closed by existing old boathouse which has been rehabilitated by BBI construction. In addition, there was limited access water way for the service crane. The removing of temporary cofferdam using UP150 Silent Piler was succeed completely on schedule without any disruption. The project using Press-in method by Silent Piler was adapted at first time for City of Oakland.

The cofferdam in Lake Calavera required to be dewatered for installation of new drain. In addition to difficult soil condition, there was no access for service crane. Surrounded by residential buildings, noise and vibration were not allowed. Press-in method achieved this project environmentally- friendlily.

The piling project site was close to Napa River Inn Hotel that had some old buildings and was filled with guests all through the year, therefore, noise and vibration were not allowed. Furthermore, there was no access for service crane in water. To overcome these hardships, Press-in piling method was selected.
