There is an urgent need to quantify at least in broad terms some of the sustainability parameters which are adopted today. This requires a specific regime of quality evaluation, assurance and audit scenario that is nonexistent at present, and the same was critically discussed. The need for an organizational set up with specific responsibilities delineated even in the conceptual and planning stages of the constructed facility was recognized. The responsibilities and role of each of the participating entities in such an organizational setup was discussed in detail. In principle, the role of the periodic external quality audit that is not associated with the construction and quality assurance setups was advocated. This is to ensure that there is a definite guarantee in ensuring the complete performance and sustainability aspects of the constructed facility by an agency that is not associated with construction in any way. The ideas of interpreting performance in terms of the reliability parameters and also the legal liability aspects were introduced.
