Geotechnical Assessment for the PNR-NSCR
Geotechnics Philippines, Inc.
Bulacan to Manila
Geotechnics Philippines, Inc. (GPI) engaged AMH to undertake geotechnical engineering consultancy services in connection with the Proposed North-South Commuter Railway of the Philippine National Railways (PNR-NSCR Project). The proposed project will be implemented by the Department of Transportation and Communication (DOTC) and funded by the Japan International Cooperation Agency (JICA). The project aims to provide a high standard mass transport system from Bulacan to Manila. Ten (10) stations will be mostly initially constructed and five (5) additional stations are envisioned in the future.
The geotechnical report included geotechnical evaluation of four hundred eighty five (485) boreholes along the alignment. Liquefaction potential was analyzed for this study, using peak ground acceleration (PGA) or 0.5. Safe bearing pressures at 1.5m depth and estimated settlements due to consolidation were calculated for the embankment areas. For the evaluation of deep foundation system using bored piles, pile lengths were determined based on the location of the competent layer and embedded at least 3m below hard soil or rock layer.
