Case study on new initiatives taken on caisson foundations and cutting edge construction at Bogibeel Bridge

Time is the essence of construction. Bridging the mighty and ferocious river Brahmaputra is a great challenge in itself. In this paper, engineering solutions are presented which are derived by adopting revised and innovative methodology, for the construction of two difficult caisson foundations, namely P2 and P3, in River Brahmaputra at a water depth of 14m to 18m, under water velocity ranging from 3 to 5m/sec, within a very short period of 4 months (from November to February) only. After adopting the revised methodology, both the caissons were successfully grounded in only 74 days and a time of 53 days was saved in comparison to earlier seasons. The fabrication/erection of each cutting edge at location was achieved in 10 days and a time of 15 days was saved in comparison to earlier seasons. This paper would immensely be beneficial for highway engineers, as it involves substantial reduction of time of execution by 42% for caisson foundation and by 60% for fabrication and erection of cutting edge at location.
