Watch out for poles toppling over

NEW DELHI: Every time you drive down the stretches recently developed for the 2010 Commonwealth Games in east Delhi - including the area near Akshardham, ITO Chungi, Noida Morh and Yamuna Pushta - you are courting danger. After two high-mast streetlight poles fell down near the Geeta Colony clover-leaf flyover due to missing nuts in the base and injured a person critically, TOI has discovered several more such poles that can topple over because of the same reason.

A TOI team visited these areas on Wednesday to discover that half of the nuts at the base of several of these 90-foot high poles were missing. One such pole near the Akshardham metro station was even found tilting at a dangerous angle. Frighteningly, neither the land-owning agency, public works department (PWD) of the Delhi government, nor discom BSES has taken any responsibility.


The way the base nuts had been removed from many poles between Noida Morh and Geeta Colony flyover showed a pattern. Several poles had three nuts missing on three corners and two nuts from the fourth corner, leaving the base structure of each pole weakened with asymmetric support.


"When these high-mast lights are secured, the base structure is planned in a way that factors in safety with respect to wind load, rain, height of pole, weight of light structure, etc. The number of nuts and their placement is also decided keeping these factors in mind. The removal of a few such nuts may keep the structure upright but it can sway and even fall due to a strong gust of wind as it's highly unstable," said a senior engineer of PWD.
