Until a few years ago, technical drawings dominated the design scenario, they were the principal tool with which designers could provide all the necessary information: elevation data, distances from surrounding roads, volumes, wall thicknesses, surfaces, etc. Design tasks were carried out using CAD software technologies, therefore with software only limited to producing 2D or 3D construction design deliverables.
With the introduction of BIM technology, which is progressively replacing typical CAD workflows in the construction sector, significant benefits are becoming evermore visible for all construction stakeholders (engineers, architects, surveyors, construction companies and public administrations alike).
But what is the main difference between CAD and BIM?
Nowadays, with BIM, there's no longer any need to produce a disproportionate amount of drawings. The use of BIM technology offers new extraordinary opportunities through 3D digital representations of different architectural and engineering disciplines to which it is possible to attach useful data at every stage of construction lifecycle.
BIM is the best way to manage every phase of construction lifecycle because it allows everyone involved to access clear and legible shared data, also improving collaboration between design, execution and maintenance aspects or asset management.
