BIM software links all objects to each other (Ibrahim & Krawczyk, 2003). Therefore, if an object of the building is changed, other objects will change too (Dickinson School of Law, 2007). In such a way, BIM makes the project flexible and time efficient since the project team will not need to work on all changes, if they need to introduce a new object or change an object of the building. Instead, the software will make all the necessary changes. In such a way, the project team will save time and can increase the efficiency of its performance because the time saved on the introduction of changes may be used more efficiently for the further planning and implementation of the project. BIM software contributes to the automation of the project planning and development that facilitates the work of the project team and helps to increase the effectiveness of the project team’s performance.
J BIM and material tracking and ordering
BIM provides not only cost estimates but also allows material tracking and ordering (Arayici, et al., 2011a). In such a way, customers can track and order all the material needed for the construction. Hence, BIM increases the transparency of the construction process and facilitates the process of ordering and tracking of materials used in the construction process.
K BIM and the virtual model of the building
BIM enables the virtual model of the building to be handed from designers to contractors and subcontractors and to the owner/customer (Arayici, et al., 2011b). Each professional adds specific data to the single shared model (Arayici, et al., 2011b). In fact, such close interaction between all stakeholders increases the efficiency of the performance of designers, the project team and contractors working on the project. At the same time, customers can introduce the changes they want in the plan developed by the project team, while the project team coordinates and agrees upon all technical issues that arise because of the change introduced by the customer with other stakeholders, such as constructors, suppliers, and others.
L BIM and the reduction of information losses
Hence, BIM reduces information losses, saves time and costs (GBS, 2007). The time efficiency and relatively low costs of BIM are accompanied by the reduction of information losses. Conventional models are vulnerable to considerable information losses, when customers do not receive the detailed information on the construction process or when constructors have little information on specific requirements of the customer (Smith & Tardif, 2009). The lack of information widens gaps between stakeholders and may raise considerable communication barriers which may outgrow into unsurpassable barriers on the way to the successful accomplishment of the project.
M BIM and the reduction of conflicts
At the same time, BIM reduces conflicts during construction substantially (McDuffie, 2006). Since all stakeholders can communicate efficiently using BIM and since information losses are minimal, stakeholders do not come into conflicts because they can solve all issues that arise at the stage of the elaboration of the project before its implementation. Moreover, even at the planning stage the risk of conflict is minimal, if BIM is applied, because BIM allows stakeholders to share information and to negotiate debatable issues, until they come to agreement.
