Project Name: MWSI- proposed 1400mm Ø Primary Lines along Alabang-Zapote Road, Las Piñas City (Package 12)
Date: February 2011
Client: Maynilad
This was a pipeline project of Maynilad along Alabang-Zapote Road in Las Piñas City. This project was secured by DMCI, and MCT was the subcontractor for the pipe-jacking portion. The steel casing was originally 1400mm Ø, but DMCI ordered to change it to 2100mm Ø. The pipeline had crossed two creeks, and the set-up done was to tunnel below the reinforced concrete box culvert. This particular work did not need the use of sheet piles to support the surrounding ground because the soil profile was hard and stable. It was accomplished on February 2011.
