Many people traditionally work with 2D-Cad which is a computertool based on x and yparameters, as well as some drawings made by hand (Nordstrand, 2009). Other companiesthat work more modernized have begun to use BIM in the workprocess. Thus, instead ofdrawing simple lines, different objects containing information are used, which are then puttogether into a model. From the model, it can then be retrieved and provided information thatis consistent with reality (Granroth. 2011).
