Nagpur, the second capital of Maharashtra and one of the fastest developing cities in India, is witnessing major growth in terms of infrastructure. The development primarily focuses on connectivity, with the Metro rail playing a major role.

Launched in 2016, the metro project has been widely praised for its speed of execution and the quality of construction.

Within the city boundaries, the project requires the highest safety standards, including seismic analysis for structural integrity throughout its service life.

Project Requirements

The fast-track project features a typical structure for its Line 1 alignment, where the viaducts support two levels of pathways: the lower one for NH-7 and the upper one for the metro rail.

Impact loading due to train movement was a major concern. Since the stretch is always busy with traffic, a solution was required that would not require revising the existing design. Additionally, minimizing delays to this fast-moving project was critical, a concern shared by all stakeholders, especially the General Consultant (GC), who sought to maintain project agility while ensuring a sustainable solution.

حل

Dextra introduced Shear Key Bars for the priority section, allowing the structure to neutralize seismic forces. This not only helped the contractor complete the work faster but also enabled the client to conduct the trial run earlier than expected.
