Building Information Modelling Management, Theory and Practice

Building Information Modelling Management, Theory and Practice
Introduction Evidence from Case Study on BIM Key Issues
Building information modelling refers to the process that is being assisted by
different contracts, technologies and tools which involve management as well as
generation of digital illustrations by functional as well as physical characteristics.
Basically, BIMs are files that can be extracted and networked or exchanged for
supporting decision-making with respect to build asset. This implies a smart three
dimensional procedure which renders AEC professionals with tools and penetration
(Improving the passenger experience in the UK's second largest airport, 2019). This
poster comprises of BIM which has been used within Gatwick Airport for creation
of full design as well as asset visibility within every stage associated with designing
of processes of project whose goals is to enhance overall implementation of design
of task along with its construction. This poster includes BIM enabled case study &
their AEC, BIM modelling management, key issues, solutions for addressing them
and lessons learned.
Gatwick Airport serves around 34 million passengers on annual basis and is one of
the busiest airport within UK. The authorities collaborated with Bechtel
Corporation and the major challenge was to modernise the airport without creating
any impact on ongoing their operations. The aim of was to make use of BIM
technology which will enable them to furnish the project within cost as well as cost
efficient manner. The Gatwick airport comprises of 227 buildings which involves 2
terminal building and six peers which are spread around 950 hectares. Due to the
huge infrastructure, it is crucial for their stakeholders for attaining quality assets at
each levels (Case study: Bechtel, 2018).
Building information modelling has become a norm within construction of project design for meeting
growth of customer demands which are being driven through UK government policies and public sector
projects. From case study, it is evident that by utilization BIM technologies enhanced representations can
be captured, collaboration can be carried out in an perfect manner, simulation tools will be used for
creating 3D models, conflicts can be resolved, processes as well as steps can be coordinated (Implementing
Building Information Modelling (BIM) at Gatwick Airport, 2018). This will aid engineers, constructors
and architects for visualizing what has to be built within the simulated environment for identification of
probable constructions, designs as well as addressing operational issues related with them. The AEC
industry look forward for different techniques through which project costs can be declined, enhancement
within quality & productivity as well as reduction within time associated with delivery of project. BIM is
liable for aligning goals, prevention of traditional contracts and this will lead to creation of clarity and
benefits for different personal involved within delivery of services with respect to Gatwick Airport. It
needs complete cross- functional support for rendering services in which each individual involved is
liable to make their contribution and make appropriate investments in terms of time for rendering
information with respect to the BIM model. Building information modelling refers to handing over the
deliverables of engineering to designers as well as engineers but for this it is important to acknowledge the
purpose. Digital BIM will allow individuals within versioning, collaborating as well as sharing the
drawing sets. For this cloud-based tools can be utilized for an instance BIM collaboration, Autodesk's
BIM 360 etc. for carrying out interaction among different aspects related with project. AEC organizations
includes estimators within the planning stage that are responsible for rendering services with an
appropriate cost estimation. This has led to extensive usage of 5D BIM. By making use of tools rendered
by them time can be saved which can be utilized in other aspects for quantification, anticipating higher
value factors like identification of construction assemblies as
well as risks associated with them (Alexander, 2013).
The biggest issue that was faced by Gatwick Airport was identification of way through which
collaboration among different contractors involved while acknowledging deadlines. The surety
has to be attained so that alterations can be made without any kind of disruption to 34 million
individuals who make use of airport each year. The distinct stakeholders possess different
objectives and this may create situations of conflict. Therefore, some models are required through
which such kind of activities can be avoided like imbalance in between traditional contracts,
handle skew among goals so that clarity can be attained (Implementing Building Information
Modelling (BIM) at Gatwick Airport, 2018). This leads to obstacles and clashes within the
contract which is signed as each individual possess different objectives through which common
goals can be used an instance can be taken with respect to this, like one engineer say that the width
of runway must be x so that at a time two flights can take off and other engineer suggest, different
runways can be made for this. The purpose behind this was same, two flights must take off at a
same time but the way to attain them was different which might lead to conflicts in between
engineers. As each perceives there method as perfect, but a mutual decision is required and this
will enable to work in an appropriate manner. For doing this some models or theories can be
utilised. Gatwick Airport needs to have a transparent design progress, efficiency within delivery,
early detection to problems, fixed cost, when, how, where and what cost is required needs to be
addressed in an appropriate manner.
On the other hand, contractor may need to have clear instructions so that quality start can be made,
more time and various other aspects related with this.
The major issue associated with Gatwick Airport was to have zero rework by which quality design
can be attained for the first time when it was developed.
Countermeasures:
Gatwick Airport opted to make use of BIM to have an affirmative impact as per their requirement. But this will be only
effective when it is used from beginning of project till it is accomplished. For addressing the issues, it is necessary that
augmented reality and building information modelling can be used as they acts as a crucial tools which will enable them to
engage their probable stakeholders. This will allow to have an interactive bid presentation that will render project plans to
clients. BIM assist Gatwick Airport for storing wide range of information associated with site like maintenance plans and
tags (Implementing Building Information Modelling (BIM) at Gatwick Airport, 2018). Apart from this, it will render
timeline as well as history of project for showing ways in which alterations within the project can be made from start to the
end.
Lessons Learned
United Kingdom has made it mandatory to make use of building information modelling with respect to future. But
this, creates a pessimistic impact on AEC industry in terms they have established certain collaboration practices as well as
processes. Building information modelling denotes process for creation as well as management of 3D building data while
developing it. This seems to be multiphase process which is liable for gathering input from different team member's
involved within, for modelling the tools along with components which can be used for construction process. It will enable to
create and distinct or unique perspective with respect to building process (Porwal and Hewage, 2013). The 3D process will
aid Gatwick Airport within attainment of their objectives by making use of visualization and collaboration associated with
building components in the early design processes which is liable for dictating modifications for carrying out needed process
of construction. In case, BIM and AR is used in an appropriate manner then it will act as an powerful tool through which
unnecessary cost and time can be saved as well as process of construction will be simplified. Furthermore, for meeting
collaboration with different contractors and ensuring that project is accomplished within specified deadlines, the project team
of Gatwick Airport can make use of Autodesk BIM solutions for infrastructure. This will lead them to migrate to BIM as it
will act as an effective means for carrying out collaboration.
