The pandemic has gripped the city, but the Brihanmumbai Municipal Corporation (BMC) has  managed to focus on the ambitious Coastal Road project. The project, which has many ‘firsts’ in its construction, also involves various new technologies which will be used for the first time in the country. This time it is monopile technology.
With the monopile technology, 176 pillars will be erected under the bridge that will be part of the coastal route. Initially three test columns will be constructed using single column technology and the process has just started. The machinery required for this has been brought from Europe and skilled technicians from abroad with practical experience are present at the site.

What is monopile technology

A bridge of approximately 34 metres width and 2,100 metres length will be constructed along the coastal route. Usually, while building bridges in the sea, the pillars are erected in a group pile manner — four pillars are built and considered as one. However, in the monopile technology, a single solid column is erected from bottom to top instead. Accordingly, 176 pillars will be constructed under the bridge.
