In this article, we will discuss building information modeling.
1. Introduction
Building Information Modelling can be abbreviated as BIM.
BIM is the process of creating and showing the model and information of the building in the form of pictures, videos, or charts using that are created BIM software likes Autocad, Sketch-Up, Revit, Navisworks, etc.
Commonly: Multiple software is required in creating BIM.
Building Information Modeling helps in proper planning, designing & also to increase the work quality
labors through animated video format that shows the way of working.
In many countries like the USA, UK, Canada, etc.
Building Information Modeling is used as the means of communication between clients, contractors & workers.
In research, it was found that BIM presentation in the tendering process increased the chance of winning a tender by 40%.
2. Details that are Shown in BIM
1. 3D- model in the form of image or video.
2. Time or schedule-related information.
3. Number and types of workers required in a specific date.
4. Cost required ( i.e. Cost required each month).
3. Software Used in Building Information Modeling
1. Autocad
2. Revit
3. Sketch Up
4. Archicad
5. Vectorworks Architect
6. Tekla Structure
7. Civil 3D
8. Navisworks
9. Data Cad
10. Autodesk BIM 360
11. Buildertrend
12. Trimble Connect
13. BEXEL Manager
14. 3D Max
4. Parts of BIM & Software Used for Each Part
a. Planning & Drafting (2D)
(i) Autocad
It is the most commonly used software for drafting. Although we can also create 3D using Autocad, we only used it for 2D drafting because of the boring environment & complexity of Autocad.
b. 3D-Design & Modeling
Commonly used software for 3D designing & modeling are:
(i). Sketch Up:
It is very easy to use and can be mastered in a very short time.
It is commonly utilized when 3D-BIM is to be created.
There are many extensions available which make it more friendly.
In the case of 4D, 5D& 6D BIM; it is less suitable because it cannot be used in the calculation of material, time & cost.
(ii) Revit:
It is more complex than SketchUp to learn & use. It is full of many features like 3D-designing materials calculation and other different analyses.
So, it is suitable to use in 3D,4D,5D & 6D.
(iii). Archi CAD
(iv) Tekla Structures
(v) Vectorworks Architect
(vi) Civil 3D, etc.
c. Rendering
Rendering is the process of making the 3D design looking realistic. Some rendering software that can be utilized are:
(i)Lumion
(ii)3Ds Max
(iii) Twinmotion
Commonly Lumion is used because of the availability of huge resources like vehicles, furniture, colors, vegetation, etc.
d. Time Scheduling & Cost showing
a. Navisworks:
It is commonly utilized for time scheduling and cost shows.
b. Bexel Manager:
Combined used of other multiple software can also be done in place of Navisworks.
e. Construction Planning & Management
Bexel Manager has commonly utilized construction planning & management software.
Types of BIM
a. 1D-BIM ( Research & Planning)
b. 2D-BIM (Drawing + 1D BIM)
c. 3D-BIM (Modelling + 2D-BIM)
d. 4D-BIM (Time + 3D-BIM)
e. 5D-BIM (Cost + 4D-BIM)
f. 6D-BIM (Building performance + 5D-BIM)
g. 7D-BIM (Facilities Management + 6D-BIM)
h. 8D-BIM (Safety + 7D-BIM)
5. Advantages of BIM
1. Maximized Efficiency
2. Better End Result
3. Less Risk and wastage
4. Improved Cost Estimate
5. Coordination and Collaboration
6. Fast detection of Conflicts between specialties
7. Easily evaluate design options
8. Life cycle of Data
9. Sound and Light analysis
10. Sustainability
6. Disadvantages of BIM
1. Cost of software
2. Technology Reliance
3. Model Ownership
4. Behaviour risk
5. Current Contracts
