Dilapidated buildings and roads

Very often we learn through media that many schools, colleges, and other public structures built in the post-liberation era are in a very pitiable state. Roofs are collapsing, slabs are fallings, beams are falling apart and so on. Normally cement-concrete structures or brick-built structures have a minimum life as we see many of our old mosques located all over the country have lasted several hundred years though built in the 13th or 14th century. Then why should the structures built now collapse? Rana Plaza disaster is an example, known globally. There must be gross negligence during the construction process. It is time to catch those contractors, designers, supervisors before another disaster takes place. Similar is the condition of roads and highways. Why should newly-built roads need repair in a year? Let there be quality control system and the offenders need to be punished for wrong-doings.
