quality control including regarding the
beneficiation, segregation and processing,
etc.

SOME POINTS REGARDING
SUSTAINABILITY
- To get the maximum benefit from the building and its services in
terms of quality, timely completion and cost-effectiveness.
- The aim is to maximize the efficiency of the total system through
appropriate optimization of each of its sub-systems.
- In the team, the inputs from each of the professional disciplines
have to be so optimized that the total system’s efficiency becomes
the maximum.
- It may be re-emphasized that maximizing the efficiencies of each
sub-system may not necessarily assure the maximization of the
efficiency of the total system.
