3.2 Future developments
The construction industry is deeply changing in the lasts years, and BIM methodology is a fundamental part of this process, leading to a more automatized industry managed by BIM softwares.
This thesis represents an attempt to deepen these aspects, trying to use BIM to reach others goal further the normal BIM modelling.
This point is occupying a central spot in the speech about construction industry and BIM, the necessity to understand which LOD is required to any task and find a way to calculate an average LOD value in models composed by different detail degree. The project management that represent a large part of this thesis becomes a fundamental tool in construction industry, but also in other industry fields. In this thesis was treated beginning from the project tasks decomposition made in the WBS code, that was made by myself after analysing the most common standards codification currently used, where was found a multitude of classification, and a future improvement is to create a common code to be used worldwide putting in contact all the various classifications.
Surely a future development is to apply also the other parts of the activity code to all elements in the project assuring firstly a more detailed plan considering any single element with its positioning attribute, that wasn’t useful in such a small project, but become necessary in larger size building, then the last code part applied to have a direct connection with the cost source and finalized to obtain a cost survey.
Another future development is the adoption of 5D BIM, for instance, software securing, training investment, and low time efficiency, lacking standards of software compatibility.
The other limitation of 5D BIM is the low LOD, which cannot extract the detailed data from the 3D model for cost estimation. The BIM models are not designed for the quantity take-off or the cost estimation, so some details will not be shown in the models, it is tough to extract the detailed quantity from elements for quantity estimation. 5D BIM provides timely communication but cannot guarantee the quality of the communication. At the end of 2016, Software Advice (UK) analyzed and reported that 50% of the investigated small and medium enterprises still conduct the cost estimation manually [16]. There are many limitations of CUBIT adoption in New Zealand and Australia, such as low accuracy of quantity take-off or detailed quantity missing. CUBIT Build soft is developed
