May 11, 2019 : HCC’s Bogibeel Road cum Rail project in Dibrugarh, Assam has been awarded the ACCE (I) Sarvamangala Award – 2019 under the category of “Excellence in construction in the field of Civil Engineering”. The Award was received by Mr. Rakesh Kumar, Project Manager – Bogibeel project during the 27th Annual award function held on May 11, 2019, in Bangalore.
The HCC team completed this project with sheer determination and grit, as bridging the mighty Brahmaputra has always been a daunting task. The river is extremely difficult to bridge due to various reasons including its ferocious and unpredictable behaviour, high currents and turbulent waters, widespread erosion of the banks, short working period, high seismicity and the sheer remoteness of the area. With the width ranging from 1.2 km to 18 km, the Brahmaputra has been bridged only four times in the past; HCC holds the distinction of building two of these bridges and has now constructed the fifth bridge.
The superstructure of the Bogibeel bridge has been constructed using special copper-bearing steel plates in order to reduce corrosion. Furthermore, due to excessive humidity in the area, a complex Corrosion Protection System specific to different components of the bridge has been implemented. To offer good stability to the heavy spans (1700 MT), seismic restrainers are provided. The bridge is designed to withstand earthquakes with magnitudes in excess of 7.0.
Prime Minister, Shri Narendra Modi, inaugurated the Bogibeel bridge on December 25, 2018. Built on the Brahmaputra River in Dibrugarh district of Assam, it is the first fully welded steel bridge and the longest rail-cum-road bridge in India.
