    The Bay Bridge demolition and reconstruction required a reinforced soil slope in the final phases of the new bridge\u2019s construction. A reinforced slope was urgently needed behind the U.S. Coast Guard building that sits at water level on the southeast coast of Yerba Buena Island. The embankment confinement system (ECS) facing alignment was originally proposed to follow contours. <\/p>\n

    However, the proposed slope of the contours varied from left to right and top to bottom, demanding custom manufacturing and complex construction.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

    Caltrans designed a 112-foot-high reinforced soil slope, sitting on top of a 21-foot-high Terramesh\u00ae system mechanically stabilized earth (MSE) wall at the bottom of the slope next to an existing gabion gravity wall. Maccaferri manufactured all the ECS-related products as part of a $1.5 million contract with OC Jones. Maccaferri Inc.\u2019s engineering team led the discussions with the contractor and Caltrans, and recommended alignment changes and a uniform slope to simplify the construction, saving the contractor time and money while maintaining the solution\u2019s quality and integrity. <\/p>\n

    The project team reinforced the 112-foot-high slope with the Green Terramesh\u00ae system. The system\u2019s angled front face and erosion control blanket are designed to help establish natural vegetation. In addition to the slope\u2019s height and complex nature, the project team discovered underground obstructions that were remnants of the old bridge. The team had to figure out how to work around an existing drainage system, manhole drain inlets, and an electrical duct bank as well as numerous columns and foundations associated with the new bridge. <\/p>\n

    Maccaferri\u2019s Terramesh\u00ae system and polymer-coated gabions were used to form the Terramesh\u00ae system MSE wall at the slope\u2019s base. After the Terramesh\u00ae system and gabions were installed at the bottom of the slope, the project team started reinforcing the slope using Maccaferri\u2019s Green Terramesh\u00ae system.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>
