BACKGROUND OF BIM:

4. What is BIM?
 Building Information Modeling (BIM) is an intelligent 3D model-based process that
gives architecture, engineering, and construction (AEC) professionals the insight
and tools to more efficiently plan, design, construct, and manage buildings and
infrastructure.
 Building information modeling (BIM) is a process supported by various tools,
technologies and contracts involving the generation and management of digital
representations of physical and functional characteristics of places.
 In this Presentation, I focus on three key benefits of working with BIM models
which include:
 Data-rich models
 Reduced rework
 High-impact visuals

5. Explanation of BIM
 BIM provides a stable platform for computer simulations and 3D models.
In addition to aiding collaborative workflows, a BIM database provides a
convenient store of architectural and design data for 3D modelling and
simulation software. These programs can be used for design and structural
purposes. Bims provides the most value for its user during construction,
when various contractors are at work on the building. BIM helps realize the
greater potential savings by creating more opportunities for collaborating,
eliminating and resolving problems
 Building Information Models (BIMs) are files (often but not always
in proprietary formats and containing proprietary data) which can be
extracted, exchanged or networked to support decision-making regarding a
built asset. Current BIM software is used by individuals, businesses and
government agencies who plan, design, construct, operate and maintain
diverse physical infrastructures, such as water, refuse, electricity, gas,
communication utilities, roads, railways, bridges, ports and tunnels.

6. Application of BIM:
 Building Information Modeling is a collaborative process for the
planning, design, construction and management of a building. It’s the
Idea of Exchanging Data using Standards. Ideally, the BIM process
utilizes a centralized digital 3D model of the building (BIM model) as
its core resource. Each construction participant contributes data to the
model and has access to data created by others. At this stage, the BIM
model consists of smaller components (BIM objects) such as doors,
walls, equipment etc.

7. CHARACTERISTICS of BIM:

8. DIMENSION OF BIM:
 3D = Geometry. The third dimension of BIM gathers the graphical data. It is the most
commonly known dimension, as it refers to the “visible” part of a BIM model. Linking
different specific models into a federated model allows to develop a clash free project.
Model walkthroughs, Clash Detection, Project visualization,
 4D = Time. The fourth dimension of BIM is used for construction site planning related
activities. It is possible to visualize and to control the progress of the activities through
the lifetime of the project. Builders and manufacturers can optimize their activities.
 5D = Costs. This fifth dimension of BIM is used for budget tracking and cost analysis.
Quantities may be extracted directly and instantly from the BIM model with a high
accuracy level.
 6D = Sustainability. The sixth dimension of BIM is used for energy assessment during
the design phase and operational phase. An efficient data collection from installed
sensors enables to better understand the building’s performance and define a strategy
aiming to optimise the building’s energy consumption.
 7D = Facility Management. The seventh dimension is used to extract and collect relevant
information related to the operation and maintenance status of the facility throughout its
life cycle. 7D is the main field where BIM model’s data can definitely make the difference

14. Implementation of BIM in Pakistan
 ABSTRACT
Construction sector of Pakistan has rapidly developed with a higher growth rate of
9.05
percent during the period 2016–2017. However, a poor record of completing the
projects in
allocated time, cost, and with desired results is observed. One of the reasons for such
poor
performance is sticking to the traditional management practices that can be easily
overcome with
the implementation of building information modeling (BIM) tools. This study
attempts to
educate the stakeholders of the public sector of construction industry in Pakistan, as
to how BIM
can help them in minimizing the problems being faced during construction. BIM was
implemented on a running construction project of a government hospital.

15. The results were then
presented to the key stakeholders, and they were asked to rank how BIM can
help them in
overcoming the problems. The stakeholders were generally convinced to use
BIM on future
construction projects, and agreed to take appropriate measures for BIM
implementation in their
departments. This research is expected to help in enhancing the performance
of construction
industry through BIM implementation.

16. CONSTRUCTION INDUSTRY OF PAKISTAN
Construction is one of the important sectors in Pakistan. It is the largest
employment
producing sector within the country as well as a vital factor for the
economic development
(Maqsoom et al. 2013). The construction sector has registered a growth
of 9.05 percent against
the last year growth of 14.6 percent (Pakistan Economic Survey 2017).
Boom of construction in
different economic zones such as Energy, Architecture and Planning,
Industrial and
Transportation, makes it a defining element for the economic progress
of the country (Gardezi et
al. 2014)

17.  CONCLUSION
Construction industry of Pakistan is facing problems of delays and
miscommunications in all
the stages of project execution, starting from the preliminary studies to the
project close out
stage. The key stakeholders are yet not convinced to adopt the modern
management approaches
such as BIM. Through this case study, the advantages of BIM implementation are
highlighted, as
BIM facilitates in cost estimation, safety, risk management, energy analysis, and
life cycle
analysis of a project. The study recommends BIM to be beneficial for the
construction sector. In
addition, major barrier in BIM adoption in Pakistan construction industry is
identified as the
unawareness among the key construction stakeholders. Thus, the presentation of
BIM process to
the stakeholders of public sector helped in convincing them. It is believed that the
public sector
authorities can be a driving force for BIM implementation in the country.
