Without getting into discussions about the subjective and the objective, we have to say that we at Cobuilder have a way of defining the truth about a product-related concept (terminology) in the construction industry. We are using a simple scientific approach like the one you most probably have also used while writing your university essays. We use credible, acclaimed sources.
The acclaimed sources in the construction industry are standards produced by the relevant regulatory or standardization bodies. Their relevance can be established at different levels starting at the global and through to the national, organizational, industrial and market levels.
