BBJ Construction Company has been involved in the construction and maintenance of many of India's rail and river bridges. The company is registered and headquartered & Heavy Plant Yard in Kolkata and reported aggregated revenue of INR737,698,000 (US$13 million) during fiscal 2007. The ever increasing traffic movement between the twin cities of Calcutta & Howrah demanded a wider and stronger bridge
in replacement of the then existing pontoon bridge. The authorities accordingly decided on building a cantilever bridge across the river Hooghly. The job undoubtedly called for greater expertise. So three engineering firms – Braithwaite, Burn & Jessop – came together and floated a new company. Thus on 26 January 1935 was born BBJ. The Braithwaite Burn & Jessop Company Limited. Nationalised in 1987, BBJ today is a subsidiary of multiple resource organisation Govt. of India Undertaking BBUNL. BBJ's engineering activity is also evident in installation of major steel plants, thermal power stations, oil refineries, fertiliser projects. BBJ has also undertaken restoration of damaged bridges, creation of fabricated industrial structures and civil construction of major commercial and administrative buildings.
