What is BIM?

BIM covers geometry, spatial relationships, geographic information, quantities and

properties of building components

V

BIM is a single integrated model representation from which all drawings & reports are

generated

Building Information Modeling is the process of

generating and managing building data during its life cycle

Benefits of BIM

Success of BIM

Anatomy of BIM

Swiss-army knife

syndrome

http://www.leisuregeek.com/images/wenger_giant_swiss_army_knife_2.jpg

The condition of needing to be equipped with the most possible tools for the

maximum number of undefined situations.

Tools or software that have a superfluous amount of functions but that are not

overly good at any of them.

BIM represent the Information

related to a building, not what you do with the information.

BIM Essentials &

Expectations

BIM applications

Generation of construction specifications Manage building data dynamically

How Virtual Reality is used

in Construction

Objective: To identify the concerns about the

impact of new arena complex will have on the proposed location in city of London

Data:

• Plan view map of the city • 3D view of the city

• 3D model of the proposed arena complex • How much and how far

• L.O.D and how realistic • Terrain details

BIM Adoption and

Implementation - MAAP

BIM Case Study

(

Miami International Airport)

Source: RISA Technologies

Challenges

Complex geometry of the vaulted roof, which functions as both the roof and the wall of the terminal building. Additionally, the cantilevered beams had to be designed for multiple load cases and uplift because Miami is a hurricane region. RISA made

checking the different load cases and load paths of the cantilevered section easy, Meagher says.

Drop of the unwanted geometry, Control LOD,

Translate the geometry to light-weight

Modify the parameters (scale, origin, association)

Enhance the data (light, textures) Building families or grouping

Develop local functional simulations

Add sensors, proximity switches Triggers for events

Build behaviors

Create scene and Environments Develop interactions and associations

Develop a control module and GUI Interact with supporting devices Publish the model
