ABSTRACT
This chapter sets out some guidance for those new to the subject on how to set about the study of building construction. Even in the digital age, where computer-aided drawings (CAD) are the standard, many employers require the ability to sketch as a key skill. Early CAD programs produced 2-D drawings that were little different from hand-drafted drawings and were still produced on paper. The use of CAD has led to the introduction of Building Information Modelling (BIM) systems in which the level of digital information can encompass all aspects of design including management processes, costing and links to contractors and manufacturers as well as the use of a building over the entire life cycle of a building. BIM is ultimately based on the Employer’s Information Requirements; these are obtained from the employer’s internal team, the construction team and the operator/s of the built asset.
