The substructure comprises cast insitu concrete piles and piers which were constructed in the river Meghna at the time of receding flood water. High water level and high stream current velocity of the River occurs in rainy season. Two dry seasons were necessary to complete these substructures consisting of 12 piers and 2 abutments. The construction ofthe superstructure, comprising segmental PC-box girders, was carried out through out the whole year even in rainy season. It must be mentioned that the successful completion of the construction of cofferdams for the substructure made a great contribution towards the completion of the whole ofthe construction works. 1) With steel pipe piles (diameter: 1.016 m, length: 28.5 m) with vertical interlocking system for 8 piers from pier P-2 to P-9. The cofferdam constructed with steel pipe piles ofP-2 was constantly watched by means of strain-stress measuring gauge for ensuring safety. 2) With steel sheet piles (type VL) for 2 piers (P-l and P-I0) and2 abutments. 3) With steel sheet piles type V for 2 piers (P-ll and P-12). 106 cast-in-situ concrete piles of 1.5m in diameter were constructed by using reverse circulation drilling method. A supersonic measuring system was adopted for the vertical accuracy of the bore holes. The lengths of these piles are variable ranging from 40.0 m to 58.0 mdepending onthe level ofthe bearing strata for the piles. The length of pile cap is II m in longitudinal direction and in transverse direction also. Pile cap concrete was poured on cast-in-situ by tremie pipe from the mixing plant directly. The thickness of pile cap is 2.7 m at the center and 2.2 m at the edge. The RL level ofthe lower surface of the pile cap is -9.5 m. Scour protection above the pile caps in the river was carried out by boulder pitching from floating vessels. The volume of the works done was 18,800 m 3 .
