When the construction was over before making the payment, the officials concerned should get the quality checked by the concerned laboratory as per the quality plan approved. Once it is as per the specifications are given by them the payment will be released. Generally, in Government tenders, there will be a warranty period. Even though payment is made the vendor is responsible for the quality till that warranty period is over. So officially the contractor will be at the receiving end. The officials will escape. If the contractor is not making profits and incurring losses, the whole burden will come on him only. The officials will ask again bribe and try to save him from the problem by twisting the facts and bringing something odd and making the people who died as responsible for the incident. These type of practices are very common in our country. Sincere people will always suffer.
