Lothian Bridge at Delhi for Northern Railway
The 128 year old arch Lothian Road under Bridge which permitted only a single lane traffic, was always a bottleneck for traffic passing under the railway track and hence it was decided to expand the area thoroughfare. ITD Cem (Then Trafalgar House Construction India Limited) rose to the occasion and installed six numbers box-shaped corridors by Box Jacking Technique, in two phases: 3 corridors were opened up in January 1990 and the balance corridors were opened up in September, 1992. The size of the central box was as large as 17m wide and 7 m high which fully occupied the entire space of the arch. Due to this construction, the busy S P Mukherjee Marg – N S Marg intersection now has a ten-lane underpass ensuring a very smooth flow of traffic.
Ramrajatola, Near Kolkata for South Eastern Railway
The Howrah Improvement Trust proposed to lay one sewer line across the existing main tracks of South Eastern Railway. The original design envisaged the conventional “Open-cut-Method” which would have necessitated the railway tracks to be kept supported on relieving girders during construction, thus disrupting the railway services. To avoid this, ITD Cem (Then Trafalgar House Construction India Limited) jacked 3m dia pipeline of 40m length through the railway embankment using Pipe Jacking Technique in a record time of 18 days and this pipe functioned as a sewer line .
