In this chapter, the research questions as determined in 1.3 will be answered. After all the sub
questions have been answered, we look at the main research question of this research.
Furthermore, the limitations and contributions of this research will be assessed.
7.1 Research Results
What are the current barriers to BIM integration and adoption within the AEC industry as found in
existing literature as well as practice?
In chapter 2.1 we looked at the barriers as found in literature. In chapter 3.2.1 we attempted to
compare these barriers with practice. While a variety of different barriers exist, we found that the
biggest barriers found both in literature and in practice were Required Training and Knowledge and
Software and Integration issues.
The former is about the high complexity of BIM models, and the costs of training personnel to make
use of everything BIM has to offer. This also means that centralizing BIM as a data source becomes
more difficult, as more users will come into contact with BIM and might need training. The latter
considers all the issues with BIM software and Integration; the difficulties with software
interoperability are often caused by varying implementations of the IFC standard, which makes
integration a challenge too. Furthermore,
Which standards, initiatives and tooling exist within the BIM domain and should be part of the
architecture/prototype?
The biggest standard that the architecture should unquestionably adhere to are the Industry
Foundation Classes (IFC). While some inconsistencies still exist between different vendors
implementing this standard, the IFC standard and file format have been accepted as the industry
standard. This standard is also often enforced for government projects.
In extension of this standard, there are various (regional) initiatives in which participants decide
amongst each other which data should be included when delivering a project as .IFC file.
