Measurability of Components

It is important that the identified components of work can be measured, i.e. identified in physical terms. Work should always be measured in accordance with some standard method of measurement, either internally established by the individual company or organisation, or externally recommended for these throughout the industry or trade. There are several good reasons to adopt such a practice. Some of them are as follows : 

1. The work of the estimator will be made more simple, more rapid, and probably more dependable. 
2. Communications between concerned personnel will be clarified, strengthened, and hastened. 
3. In the event of a dispute, there will be some precedents on which the estimator can rely.
