Revision as of 11:42, 16 September 2016
As the construction industry evolves, the demand for more complex and unique constructions increases, and the risk for failure increases with it. The Project Manager, in the field of construction, is faced with great deals of uncertainties, high complexity and high risks of failure. In order to carry out a successful project, it is advantageous to make the project more transparent, optimize the process and the communication between the active stakeholders of the project. With the increase of digital documentation in construction, the aspect of Information and Communication Technology (ICT) is of great importance, and within construction, Building Information Modelling (BIM) has become an effective tool for the Project Manager to reach the desired goals of a project within the given constraints.

Definition of BIM
BIM (Modelling) is a digital management tool, containing BIMs (Models). The concept of BIM is to create an intelligent platform for sharing data and construct the building virtually, before starting the physical construction. [1] The models used in BIM are parametric object based, meaning that each object contains data about how it can interact with connected objects and
Historical development
The 2D construction drawing has been used for centuries and for complex constructions, physical models have been used to get a better understanding of the BIM, as we know it today, has been 40 years in the making and already in 1975, Charles M. Eastman mentioned several disadvantages of both 2D drawings and the physical 3D models and described the ideal vision for a digital, multidisciplinary 3D model with the possibility of extraction of 2D drawings, lists of quantity for cost estimation and automatized clash-testing. [2] The “Building Description System (BDS)” approach, described by Charles M. Eastman, was further developed during the 70s and 80s and was in the USA referred to as “Building Product Models” and in Europe as “Product Information Models”. These two
Application from a Project Managers Point of View
Building Information Modelling (BIM) can be applied to any size of construction project.
Managing following….:
Complexity
As a construction projects are highly dependent on coordination of multiple fields of construction and therefore multiple people from different organizations, [3]
Uncertainty and Risks
In every project, the Project Manager is faced with uncertainties and risks, wherefore it is important to be able to act and react to unexpected events, exploit possibilities and plan for the unknown. In construction, the most common uncertainties and risks are time and economy overrun due to failure in communication, changes in the work/design, complications on site etc. [4] By using BIM as a management tool, some of these risks can be reduced. The
Stakeholder
The stakeholders of a construction project span from the professionals in the decision making and design phase, such as engineers, users, neighbors, investors etc. The 3D visualization part of BIM can be used to manage stakeholders expectations as it gives a more relatable visual of the product, in comparison to the 2D drawings.
Tools
When using BIM, it is important to use the right software for the extended desire of use, and to ensure, that the different chosen software are compatible. Following list some of the more popular software for each use of BIM:
=== 3D Model === Autodesk Revit, Archicad === Clash Test === Navisworks, Solibri
4D model (3D + time)
(Time schedule) MS Project (Simulation) Navisworks
Benefits
The benefits of BIM as an ICT-tool in construction are closely related to the actual use of the model. BIM has the possibility to be an effective tool for managing multiple challenges in construction projects and in the following, the benefits listed by Marketing Analytic, Rachel Burger [5], is elaborated.
3D visualization of buildings
The 3D visualization of a building is the core of BIMs.
Change management
(clash tests, revisions) By using a shared server (e.g. Revit Sever) a central model can be created, for all the discipline models to be linked into. By linking the models together, changes in one model, are automatically The 3D models from the architects and all the engineering disciplines can be tested for clashes between the models.
Construction simulation
(4D) The time estimation can be visualized with adding the time-aspect to the 3D model The 3D model can be combined with a time schedule of the project in order to simulate the construction from start to finish.
Data management
(quantity and cost estimation) The BIMs of today, can contain large amount of information, that are automatically shared along with the model itself.
Operational management
When the construction is done and the building has been handed over, the model can be further used for operation and maintenance of the building. The Facility Manager can use all the detailed information, connected to each component in the model and, ideally, it can also be used for repair, as the location and specific type of product can be extracted from the model for e.g. ordering new windows or doors for replacement.
Limitations
As mentioned previously, BIM can be applied advantageously in any size of construction project, however, at the current state of BIM adoption, the economical cost/benefit is more obvious in the larger, more complex construction projects. As BIM requires 3D modelling done for all engineering fields (e.g. water, plumbing, ventilation, construction and electrical) in order to gain the most value in terms of clash-testing,
