Construction Phase—Large Diameter Pipeline Seismic Retrofit Mitigates Landslide Hazard
The Santa Clara Valley Water District (District) initiated the Penitencia Delivery Main and Penitencia Force Main Seismic Retrofit Project (Project) to improve the seismic resilience of three critical water supply/deliver pipelines that serve the District’s Penitencia Water Treatment Plant (WTP) in San Jose, California. The most important objective of the project is to retrofit the existing pipelines to protect the life-safety of nearby residents and the Noble Elementary school. The Project planning phase began in 2013 and final design was completed in December 2015. Construction began in April 2016 and is scheduled to be completed in December 2017. The project includes the following key innovations: (1) design for large landslide displacement: the landslide and seismic hazard evaluation estimated the landslide displacement as 7.7 ft (seismic) and 1.7 ft (creep), for a total displacement of 9.4 ft over the 50-year design life; (2) sophisticated finite element modeling: the project team developed the design with a sophisticated 3-D model of the landslide and pipeline interactions; (3) seismic resilience: the project includes several design features to improve the seismic resilience of the pipelines at the landslide toe. The seismic resilience features will provide the ability to shut-down the pipelines during a failure, provide temporary bypass connections to return the facilities to service, monitor pipeline displacement, and monitor seismic events; and (4) constructability challenges: the district, contractor, and project team solved several constructability challenges related to working within the 50-foot easement, sequencing work within the protected bird buffer zone, and installing the ERDIP pipelines to meet the tight construction schedule. This project includes unique challenges of designing for large displacement along the axis of the pipelines which loads the pipelines in compression. This project also has a high visibility within the community because of the risk of failure and proximity of the project within the residential neighborhood.
