Definition of Blueprint

A blueprint is a set of approved building drawings necessary to be put in place before construction commences. It is drawn by a draftsman or an architect on transparent paper and later printed on paper. Blueprint is the means of communication between the builders and the architects. Blueprints are the complete drawings builders use at their building sites to build. Blue prints are also called working drawings. While the blue print is made by the architect, it is the duty of the builder to interpret it correctly. Mistakes or errors could be too costly; therefore, blue reading requires high-level knowledge of architectural and engineering drawings. It also requires ability to understand measurements and to measure accurately. An example of blueprint is the building plan, shown below:
