2. WHAT IS BIM ?
 BIM :Building Information Modeling.
 Existed since the 1970s.
 The term 'Building Information Model' first appeared
in a 1992 paper.
 Popularly used in 2002 when Autodesk released a
white paper entitled
 "Building Information Modeling”
 BIM isa digitalrepresentation of the complete physicaland
functional characteristics of a built asset.

4. THE BIM CONCEPT
BIM= Building Information Modeling
Also known as „Virtual Building” or
„Building Simulation”

5. VARIOUS DIMENSION IN BIM
2D 2D Drafting line floor plan, elevation,sectional,
Reflected ceiling plan
3D 3D modeling better visualization
4D 4D Time scheduling or project planning.
5D Cost estimation
6D Energy efficient
7D Preperation of handover the documents for operation and
maitanence.

8. Who can take advantage of BIM

9. BIM USES
⯈ Project Definition, Planning and Pre-Design
⯈Architectural Modelling (Design)
⯈Structural Modelling and Analysis
⯈MEP Modelling and Analysis
⯈Construction Models
⯈Facilities Management/As-built Models

13. ANALYSIS, COORDINATION-BIM
Further processing the BIM data
allows a wide range of
analytical activities:
 Code checking (collision detection)
 Energy efficiency analysis
 Structural analysis

19. PRODUCTIVITY GAINS
Productivitygain isone of the major benefitsof usingBIMand isthe
top metric organizations expect to improve when they adopt the
technology. Primarily,BIMrealizesthisgain through itsabilityto:
 minimize project management
 fostercommunication and co-ordination
 identify errors early
 reduce rework
 reduce costs
 improve quality.

20. Problems Faced When BIM Is Not Used
 Workflow of data and details documentation
 Improper schedule of work and monitoring
 Cost estimate is tedious and not accurate
 Poor decision making
 Digitalization of data is less
 Clash detection and coordination becomes very difficult to notice
 Reinforcement details in junctions
 Energy analysis

21. Advantages of BIM
 Create and review multiple design scenarios during design
phase
 Generation of 3D massing models, as well as 2D detailed
drawings at any stage
 Earlier collaboration of multiple design disciplines
 Making fewer errors and corrections in the field
 Better specifications, estimations, schedules, and compliance
to codes
 Automatic details correction when changes are made to design

22. Disadvantages of BIM
 Complexity of software used for BIM
 Cost of software
 Lack of BIM knowledge
 High end specifications hardware
