Thiruvananthapuram: As protests against SilverLine project are intensifying, concerns over impending impact on nearby houses and buildings have emerged. The Detailed Project Report (DPR) has implicitly hinted challenges to the houses and buildings near the proposed railway line.

DPR says when high-speed train passes through there is chance of tremors in the areas adjacent. This in turn may affect the agility of old buildings even if it is outside buffer zone. The type of soil and its strength will also govern the agility.

Some houses /buildings in the buffer zone of existing railway line were already strengthened. But, apparently, they are not equipped to withstand the intensity of tremors from special line in which high-speed trains are supposed to run. Also the houses/buildings outside the buffer zone limit, even if its 500 m radius away, are prone to cracks if foundation is not proper.

Meanwhile, it is important to note that even during the construction process, the locals will have to suffer issues like noise pollution. DPR says precautions to avoid sound pollution should be taken while construction is progressing. This includes use of machinery and equipment with minimal sound. The preventive measures are mentioned to avoid health issues from sound pollution for the people who are living within 500 m radius.

K-Rail claims that only 10 metre buffer zone is needed while DPR suggests construction activity will require stretch of land more than that. Reportedly, in some areas, to transport construction materials the width of the roads should be widened. This in turn may result in demand for more land. In some areas piling will be needed. The waste generated from it may trickle down to nearby regions.

According to renowned academician and environmentalist RVG Menon, the DPR has not detailed on the challenges it would pose to the locals. He termed the DPR as incomplete.
