Pier E Redevelopment
The project specified “No-vibration sheet piling” for the construction of two shafts used for a new lifting station in an area adjacent to existing 54” gas lines. In addition, there was restricted construction space and a difficult subgrade condition which consisted of a very dense clay layer, a high water table, and unpredictable obstructions (old pipe, old road, etc.). The installation of temporary sheet pile shafts using the SCZ675SM, with the Crush system, succeeded without any disruption. This is the first project constructed by Zefiro in the Port of Long Beach using the Silent Piler and Press-in method. The project is still under construction.
Hueneme RD Recycled Water Pipeline Project
The project required the construction of two shafts to install new sewer pipe with a micro tunneling machine. The shafts needed to be constructed adjacent to existing water lines, electric power lines, and telephone cables. The installation of a temporary shaft using the UP150 and pre-augering the soil, succeeded without issue. This is the third project constructed by Zefiro in the City of Oxnard using our Silent Piler.
Calleguas Salinity Pipeline Phase 2A
The project consisted of the construction of two shafts to install a new, 30” reclaimed water pipeline. The shafts were installed using the Silent Piler due to the deteriorated condition of the existing Calleguas Creek levee. Additionally, there was a difficult subgrade condition which consisted of a very dense gravel layer and a high water table. The owner specified use of the no-vibration method, and the installation of temporary shoring with UP150, preaugering the soil, was successfully completed without any issues.
LADWP Open trench construction in West Los Angeles
DWP MWD LA29 70' Deep shaft construction in West Los Angeles
The project requires the construction of two shafts and 200ft open cut to install a new, 98” sewer pipe using a micro tunneling machine. The shafts need to be installed adjacent to an existing, old water pipe (12” away) and residential apartments. There is a difficult sub soil condition which consists of a very dense layer of gravel and a high water table. The installation of a temporary shaft using the SCZ675WM with a 200GPM discharge water jetting system was successfully completed without any issues. The installation of 90” of sheet pile using the Press-in method was the longest in sheet pile driving history using the vibration free method.
