Bang na - Bang Pli - Bang Pakong Expressway Project

Bang na - Bang Pli - Bang Pakong Expressway Project Na-Bang Pli-Bang Pakong expressway is a 54km-long elevated expressway, being one of the sections of Bang Na-Chonburi Expressway. The expressway project was awarded by the Expressway & Rapid Transit Authority of Thailand to Joint Venture BBCD, consisting of Bilfinger+ Berger, Ch. Karnchang Public Co., Ltd. and Dywidag. 27.2mwide precast concrete segments form the decks (span lengths 39.30m-44.40m) being supported by mainly 13m-high Y-columns and by portal frames at the ramp sections. The elevated road section beyond KM 28+000 is mainly supported by bored piles with base-grouting while the remaining sections are supported by driven pre-cast concrete piles. 50mm diameter steel tubes for sonic logging test were also used as access tubes for tube-a-manchette grouting circuits in pile base grouting.
