The Mumbai Metropolitan Region Development Authority (MMRDA) on Saturday said that it has completed the concrete casting of an enormous pile foundation cap dedicated to the Shunya iconic cable-stayed bridge.

"The Shunya Iconic Bridge is a cable-stayed bridge that is under construction to support the Metro Line-2B viaduct crossing Vakola Nalla. This extensive bridge accommodates a length of 130 metres in total, with 80 metres of the same solely dedicated to the long main span across Vakola Nalla. The remaining 50 metres of the length corresponds to the anchor span. Today, a huge pile cap has been cast for the Shunya Iconic Bridge. This event marks a major progress in the construction of this elegant bridge," the MMRDA said in a statement.

The measurements for the pile foundation cap are 20.59 m x 11.979 m x 3 m. The concrete quantity of the pile cap is about 670 cubic metres, and it has a reinforcement of about 197 metric tonnes including a pedestal of about 45 metric tonnes. 75 Dia VSL 835/1035 threaded stress bars (FFT Bars) were chosen for being embedded with the pile foundation cap. The FFT bars are 120 in number, and their utilisation reinforces the pylon base to greater proportions, said MMRDA.

The MMRDA said that it has taken effective measures to maintain optimal temperatures using concrete temperature monitoring. Temperature monitoring devices and sensors are embedded across the pile cap on three different levels, categorized by the aspect of depth. The concrete temperature monitoring system oversees the rises and falls in temperature, while cold water and ice flakes are employed to mitigate the effect of heat on concrete. Water sprinklers are used to maintain the transit mixers in a wet state, while hessian cloth is used to cover the same. The methodical incorporation of planned activities alongside the unwavering dedication of the construction teams is leading to steady and significant progress.

"MMRDA is fortunate to have earned the dedication of highly talented engineers, consultants, contractors, and construction workers in all of its dream infrastructural pursuits, time and time again. Shunya Iconic Bridge is yet another marvellous architecture from MMRDA designed to symbolize the contribution of "zero" to the whole of humankind. The unmatchable skills of our engineers are currently giving life to a designing masterpiece, and their skills are being put to great use through the consistent efforts of our associated consultants and contractors. We are now witnessing the magic that happens when the finest equipment meets one of the most dedicated teams of professionals," said Dr Sanjay Mukherjee, Metropolitan Commissioner, MMRDA.
