Role Of A Project Manager Within A Building Information Model

Better Essays

Before we delve into the role of a Project Manager within a Building Information Model (BIM) project and how, if at all, that role has altered, lets step back and understand how BIM evolved. The concept of BIM has actually existed since the 1970’s with the term 'building model ' first used in papers in the mid-1980’s. However, it wasn’t until around 10 years later that the terms 'Building Information Model ' and 'Building Information Modelling ' (including the acronym "BIM") became more mainstream. Traditional building design has been largely reliant upon two-dimensional technical drawings (plans, elevations, sections, etc). Building Information Modelling extends this beyond 3D, it is a parametric 3D model enhancing the three primary spatial dimensions (width, height and depth) with time as the fourth dimension and cost as the fifth. BIM therefore covers more than just geometry, it also covers spatial relationships, light analysis, geographic information, and quantities and properties of building components (for example, manufacturers ' details). For us professionals involved in a project, BIM therefore enables a virtual information model to be handed from the design team to the main contractor and subcontractors and then on to the owner/operator with each professional adding discipline-specific data to the single shared model. One of the benefits of this approach is that there is a reduction in the loss of information that traditionally occurred when a new team takes
