Mr. Sagar Kagathara gave a presentation on how Building Information Modeling (BIM) is changing the construction industry. He began with an introduction to BIM, explaining that a BIM model is a database rather than just drawings, and any changes made are automatically propagated through all representations. BIM is a process that helps optimize resources throughout an asset's lifecycle. Key benefits of BIM include visualization, clash detection and coordination to reduce rework, design optimization, accurate quantification, and facility management integration. Examples discussed included scan-to-BIM for as-built modeling and 4D simulations. Emerging technologies that go beyond BIM include cloud data access in the field, augmented reality, 3D printing

2. INTRODUCTION TO BIM

3. What is BIM?

4. BIM Model : A Database, Not Drawing
Drawings (Plan, Elevation &
Sections, 3D Views) & Quantity
Schedules in BIM Model are
different representation of the
same model.
Hence, a change made anywhere
in the model instantly and correctly
propagates to all drawings.
This eliminate possibilities of errors
& inconsistencies which otherwise
may surface at site.

5. BIM is a process and it helps in optimizing the resources throughout the lifecycle of the asset

12. BENEFITS

13. Visualization
It is a great opportunity for design engineers to visualize and look at their designs and make informed decisions

14. Clash Detection & Coordination
Well coordinated design can help reduce rework on site (and hence save Time & Money) dramatically.

15. Clash Detection & Coordination

16. Clash Detection & Coordination

17. Design Optimization
BIM Model can help taking informed decisions to designers, avoiding any surprises

18. Accurate & Instant Quantification
All modeled elements can be quantified instantly & accurately.
This helps developers and contractors to have a realistic idea of the project costing.

19. Accurate & Instant Quantification

20. Coordinated Drawings
3D Coordinated drawings can be produced with all services highlighted in single drawing.
This is extremely difficult in conventional methods.

21. Facility Management + BAS
Integrating Building Automation Systems (BAS) with BIM enables sensors’ data tracking within 3D. Quickly track HVAC systems’
performance by reviewing individual elements’ data points values.

22. Integrated Project Delivery (IPD)
A common discussion platform allows all stake holders of the projects to coordinate their designs in a single integrated
environment during their coordination meetings.

23. 4D Simulations

24. EXAMPLES

25. Case Study : Scan To BIM

26. Case Study : Scan To BIM
With technologies like laser scanning, existing buildings’ as-built conditions can be captured in form of point clouds.
These point clouds can be converted into 3D BIM models for documenting buildings.

Beyond BIM

30. Beyond BIM : Cloud Data in the Field
“My dream is to do buildings paperless. And it can be done”
- Frank Gehry
The company has recently announced that its GTeam software will now make use of Box, a cloud based storage system.
The GTeam software was used and developed during the design of the “New York by Gehry” skyscraper.

31. Beyond BIM : Cloud Data in the Field
Construction field management software combines mobile technologies for on-site use with
cloud-based collaboration and reporting.

32. Beyond BIM : Cloud Data in the Field
Construction professionals no longer have to carry pads of paper and tubes of drawings on the job site.
Goodbye, blueprints!
No need to carry thick bunch of papers on
construction site
Much better communication
Create, manage and respond to issues and
checklists on tablets, push them to cloud
instantly
Hello analytics
Use standard reports out of the box and schedule
reports to automatically send to all project team
members and subcontractors

33. Beyond BIM : Field BIM
Generate points in BIM models
In the field, locate points with a laser-guided equipment with
pinpoint accuracy
A single person can lay out hundreds of points in a day
Record actual field points into equipment & publish this as-built
data to BIM

34. Beyond BIM : Augmented Reality
“3D digital data superimposed with physical environment using GPS location in real time gives you a
three dimensional view relative to where you are standing.”

35. Beyond BIM : Augmented Reality

36. Beyond BIM : Augmented Reality

37. Beyond BIM : 3D Printing
Behrokh Khoshnevis, a professor of industrial and systems engineering at the
University of Southern California has been working on a method that uses the
printing technology to create a 2500 square-foot buildings in under 20 hours.
With support and funding from the US military as well as NASA

38. Beyond BIM : 3D Printing
A Chinese company built 10 one-story homes in
24 hours using 3D printing technology.
3D Printed House to Be Built In Amsterdam
Working with another Dutch firm Ultimaker, Dus Architects have
developed the KamerMaker (Room Maker), a 3D Printer big enough to
print chunks of buildings, up to 2x2x3.5 meters high, out of hot melt, a bio-
plastic mix that’s about 75% plant oil. The chunks can then be stacked and
connected together like LEGO bricks, forming multi-story homes whose
designs can be adapted according to users’ needs/desires.
WinSun Decoration Design Engineering built the houses in
Shanghai using four giant 3D printers, which are each 10 meters
(33 feet) wide and 6.6 meters (22 feet) high, according to Chinese
news agency Xinhua.
They produce a mix of cement and construction waste to construct
the walls layer by layer, a process much like how a baker might ice
a cake.
