Construction quality and failure

When high profile real estate developers announce landmark projects, to attract investors and property buyers they will usually claim that the best construction material, equipment will be used, and the construction will adhere to the most stringent construction standards. However at times it is not surprising to hear the news that the Worlds Best Construction Fails, when a high profile structure like a bridge or building will collapse during construction or within a few years though the firm which built the structure is well known and reputed.

There is a saying that there can be hundred lies or versions about an incident and there is only one truth, similarly for construction and engineering there are thousands or millions of mistakes which can be made, while building the structure. Most companies have systems in place to ensure that the construction will be fool proof, however negligence of a single employee, vendor for a short span of time can cause the failure of a structure costing many millions or billions of dollars
