IMPACTS OF BIM TECHNOLOGIES ON CONSTRUCTION PRACTICES
1.Introduction
Technology development in all the field improves the performance
of the existing system. Without modernization, we cannot ensure
sustainability. Similarly, the construction industries also change day by
day. The BIM (Building Information Modeling) technologies change the
growth of the construction industries to the next level. Many countries
support these concepts to improve the performance of the construction
process. BIM technologies also reduce the wastages involved in the
process (Almaimani and Nawari, 2017). In a recent trend, all the big
construction companies are adopted this technology. Also, some medium
scale companies are in the dilemma regarding the adoption of these
technologies. But these technologies are showing the visual evidence to
their performance. Here, the overview of BIM technologies and its impacts
on the construction industries are described (Cao, Li and Wang, 2014).
Both negative impacts and positive impacts of BIM technologies are

BIM Stands for Building Information Modeling. This system helps to develop the
building or product by coordinating the various processes like designing, planning and
analyzing etc. This technology is mostly helpful for who involved in Architecture,
Construction, and Engineering fields. It reduces the various complications involved in
the process. BIM technologies reduces the risk involved in human errors during the
coordination of other works. In general, the typical Construction project starts with the
design process (CAO, LI and WANG, 2017). At first, the structural design of the
building will be developed. Then the architectural and MEP design will be developed.
And finally, all the three are coordinated during the construction process. In the
conventional process, all the three designs are tested individually. But it is not possible
to test the entire system. This is the main advantage of BIM technologies.
Through this technology, the designer can be able to develop the 3D model for the
building. The developed model is supported by the various set of information. In other
words, BIM technology helps to develop the building model. Then, test the developed
model to ensure safety and other parameters. Finally, it helps to improve the planning.

3.How it shows impact on the Construction Industries?
BIM technologies change the entire process involved in the construction industries. It creates a revolution in the entire construction
process. In this section, the major areas which can be improved by the BIM implementation are discussed. Here a brief overview of five
important areas and how it changed by the implementation of the BIM technology is found.
3.1 Impacts of BIM in Design Development

3.2 Impacts of BIM Implementation
in 3.2 Cost Estimation process
In the cost estimation, the implementation of BIM creates a noticeable impact. It improves the accuracy of the cost estimation process.
Even a semi-skilled BIM specialist can carry out the cost estimation more accurately than the well-experienced cost estimator. In the
conventional process, the cost estimation process is done by the skill and experience of the person (Fridrich and Kubečka, 2014). But in BIM,
each brick and bolt are considered for the cost estimation. So the accuracy of the process is too high.
The most important area which can be improved by the BIM implementation is
construction design. BIM technologies can reduce the errors in the construction drawings into a
noticeable amount. It also reduces the complexity involved in the design process. BIM tools
improve the effectiveness of the construction design. It also gives opportunities to develop the
design of the building (structural design, architectural design, and MEP design) (E. Hedges, 2012).
Also, it gives the better visualization than the normal CAD design. It also reduces the time
required to develop the design. Also, the developed design is easily analyzed with the help of BIM
tools. By using BIM, we can develop the draft to 3D model simultaneously. But in the
conventional method, we need to develop each thing separately. Because BIM facilitates all
features under one roof.
