South Luzon Expressway (SLEX) Seven bridges

Foundation Specialists, inc. was awarded the rehabilitation and upgrading of seven bridges and the new construction of a major viaduct , the San Juan Bridge, across the San Juan Water Reservoir, along the South Luzon Expressway (SLEX) by the  Expressway new operator MTD.
The South Luzon Expressway is the major link between Metropolitan Manila and all the provinces south of Manila in the Philippine Island of Luzon.
The lack of a reliable railway system, makes SLEX the strategic link to the developing and the developed South Luzon Cities and Provinces, including the City of Batangas, with its new international container port, recently completed.
The South Luzon Expressway was built by the Construction and Development Corporation of the Philippines (CDCP) in the nineteen seventies, when the overall Philippine population was about forty million, and was never upgraded until the present rehabilitation and expansion, in spite of the fast increase of population and of vehicles in circulation..
The rehabilitation and retrofitting of bridges along SLEX, as well as the construction of new bridges , box culverts, approaches and slope protection , was given by the expressway operator MTD to Foundation Specialists, inc., in the year 2007..All new  foundations were done with large diameter bored piles.
