What is BIM?
• BIM is an intelligent 3D model-based process that gives architecture,
engineering, and construction professionals the insight and tools to
more efficiently plan, design, construct, and manage buildings and
infrastructure.
(According to Autodesk solutions)
• BIM is a digital representation of physical and functional
characteristics of a facility. A BIM is a shared knowledge resource
for information about a facility forming a reliable basis for decisions
during its life-cycle; defined as existing from earliest conception to
demolition.
(According to US National Building Information Model Standard
Project Committee)

What is BIM?
• BIM is a digital representation of
the complete physical and
functional characteristics of a built
asset.
• A BIM model can contain
information on design,
construction, logistics, operation,
maintenance, budgets, schedules

5. • Lidar also called ( LIDAR, LiDAR,
and LADAR) is a method for measuring
distances (ranging) by illuminating the
target with laser light and measuring the
reflection with a sensor.
• Differences in laser return times and
wavelengths can then be used to make
digital 3-D representations of the target.
• It has terrestrial, airborne, and mobile
applications
Lidar- Light Detection and Ranging

6. Process of the BIM Model Development

7. • Through three-dimensional point cloud model produced by terrestrial laser
scanners instrument scan output, after the format conversion processing, import
reverse engineering software to build faceted manner become triangular mesh
model, but so far all processes, outputs three-dimensional models are the object
does not contain any information related to the model, only a three-dimensional
model can be displayed visually, but through integration with BIM platform, the
model import Autodesk Revit 2014, which can set up this model a variety of
information associated to new models, extending a three-dimensional model of
the overall application efficiency.
Process of the BIM Model Development
• Using Revit can add a variety of information in model, such as materials and
functional properties of the model related to, these data with the model
correspond to each other and are having connectivity

Evolution of BIM
1963
The early days of BIM date all
the way back to the 60’s with the
advent of Computer Aided
Design (CAD) software.
1975
A prototype known as Building
Description System (BDS) was
presented that laid the foundations
for BIM as we know it.
1977
GLIDE (Graphical Language for
Interactive Design) was created which
had many of the features included in
modern BIM systems. These early
versions of BIM were very basic but
enabled more efficient prefab
construction
1977
A BIM platform known as RUCAPS
(Really Universal Computer-Aided
Production System) was used to for
the prefab renovation of Terminal 3 at
Heathrow Airport.
1980 & 90
saw pioneering software such as
ArchiCAD take things further
towards virtual 3D design and
construction
2000
Revit was born
2001
Navisworks released

• This large-scale infrastructure project is one of its kind involving adoption of digitization process in
construction i.e. first time implementation of 3D, 4D & 5D BIM technology for engineering
coordination, BOQs, time & const control etc. in Water Supply Scheme project in India.
• Big challenge is to compile and bring the 3D BIM models of 88 km pipeline and Intake Well,
Membrane Bioreactor (MBR), Water Treatment Plant (WTP), Master Balancing Reservoirs on a
single digitized platform.
• Establish the model based scheduling, productivity monitoring, automated take-offs, cost tracking
and most importantly, perform the clash detection & rectifications of the engineering of the complete
project before execution of actual work at site.
• Meet the expectation of building 5D BIM solution as the backbone of the project management
during the design & build phase after having ‘Go-live’ and subsequently, for operations &
maintenance of the project.
• Keep the MMRDA & top management of L&T updated about the planned versus actual construction
status of the project and providing decision making support for taking corrective actions, as required.

• The increased sophistication of CAD and BIM technology has coincided with growing challenges in the
construction industry.
• Shortage of Qualified Workers : 70% of contractors admit that they struggle to find enough skilled
tradespeople or qualified engineering professionals to meet growing demand. 47% of these contractors say
that this could lead to safety issues as they will have to rely on unqualified or under-skilled staff. BIM can
help to ease some of these concerns as the higher levels of information conveyed in a BIM model means
that workers won’t need to rely so much on prior knowledge and experience to solve problems on site.
Safety concerns can also be alleviated to a degree, as the BIM model will highlight clashes, hazards and
other potential problems such as site overcrowding.
• Generational Tensions: As more millennials enter the workforce, they have a very different outlook and
skill-set to previous generations. Most people under the age of 30 are skilled, or at least competent, in
using technology. By adopting BIM technology, conflicts between senior and junior engineers can be
resolved, as they can combine skills to assist each other.
Need of BIM

46. 46
• Keeping up with Technological Change : Technology has transformed most aspects of modern life, and
construction is no exception. Companies that don’t keep up with the changes will find themselves left
behind the competition. The pressure created by these rapid changes can divide workforces and managers,
and if the technology isn’t implemented well, it can complicate workflows. Therefore, it is best to take a
gradual approach when implementing new technology to avoid ‘upsetting the applecart’ too much.
• Environmental Sustainability: It’s estimated that the construction industry produces between 25-40% of
global carbon emissions. BIM is ideal for improving sustainability as it can help to design more energy
efficient buildings and reduce waste. Designers can analyse alternatives that will improve energy efficiency,
optimize for natural light and ventilation, evaluate viability and placement of solar panels and more.
• Project Complexity: New building techniques, tools, and resources are used with greater frequency every
day. Research shows that only 30% of companies deliver projects within budget and half that amount
deliver on time. BIM can help to reduce the complexity, or at least simplify the way design information is
presented. The resulting cost and efficiency benefits of BIM are needed now more than ever.
Need of BIM

47. 47
• Productivity gain: Productivity gain is one of the major benefits of using BIM and is the top metric
organizations expect to improve when they adopt the technology. Primarily, BIM realizes this gain through
its ability to:
 minimize project management
 foster communication and co-ordination
 identify errors early
 reduce rework
 reduce costs
 improve quality

BIM Adoption challenges - INDIA
• Lack of Expertise
• Lack of Awareness
• Cost-effectiveness for small projects
• Resistance to change
• Lack of cooperation between stakeholders

49. 49
Way Forward
• BIM is promising and more advantageous compared to
the traditional process.
• BIM is still in its infancy stage in India. Still has not
reached a stage where users can boast about the cost
savings for a project due to BIM implementation
because a majority of BIM users in India have not seen
a full cycle of BIM implementation for their projects
• In India, universities should start teaching BIM as an
academic course to make the people perfect in this field.
