BMC to Use Mono-pile Technology Bridge Construction

The construction work of Mumbai’s Coastal Road project initiated by Brihan Mumbai Municipal Corporation (BMC) is going on in full swing despite the Covid-19 pandemic. In the coastal road project, new technologies have been adopted to ensure timely completion of work and as part of this, now BMC has decided to use Mono-pile technology for the construction of bridge pillars. Total 176 pillars will be raised using this technology. This technology is environmentally friendly as it reduces construction work saving time and cost significantly, informed the BMC through an official statement issued by its Public Relations Department on 29th April. For the implementation of Mono-pile technology, initially, three pillars will be built for examination. The required raw material has been procured from Europe and in presence of technical experts having knowledge of this technology and with proper guidance the civil work has been initiated, informed Suprabha Marathe, Chief Engineer, Coastal Road project. Mumbai’s coastal road bridge will be 2,100 metres long and 34 metres wide. 15.66 metres long interchange is also under construction. Generally while constructing a bridge above sea, river, lake, creek among others the ground pile technology is mainly used. However, in this technology for each pillar four pillars need to be built. While in Mono-pile technology a single pillar can be raised at one span. Following which, the numbers of pillars have been reduced to 176 from 704 now. Due to the reduction in the number of pillars the sea surface will be used less proving it to be an environmentally friendly technology. Moreover, it will save construction time and cost of the project substantially. By using the Mono-pile technology each pillar diameter will be of 2.5 metres, 3 metres and 3.5 metres comprising three different size diameters. Depending upon the position the size of pillars will vary. Since the Mono-pile technology for the construction of bridge pillars is being used in India for the first time, BMC has made sure that Mumbai’s coastal road project engineers and consultants are trained for that.
