ABSTRACT
This chapter describes the methods for the production and sharing of project information that are available to the AEC industry. Though some firms continue to use traditional manual drafting techniques many have adopted 2D computer aided design (CAD) systems and an increasing number have progressed onto 3D parametric object-based design systems and Building Information Modelling. 2D CAD tools provide easier ways of editing and copying drawing content. Information sharing can be achieved by the transfer of drawing files and this has led to improved levels of collaboration between members of the design team. Building Information Modelling involves more than the adoption of a 2D CAD or 3D object based tool. It is founded on the development of a Common Data Environment for sharing information between the members of the design, manufacturing and construction teams. The structural model was further developed by the steelwork contractor for fabrication.
