BUILDING INFORMATION MODELING (BIM) WAS INTRODUCED NEARLY TWELVE YEARS AGO TO DISTINGUISH THE INFORMATION RICH ARCHITECTURAL 3D MODELING FROM THE TRADITIONAL 2D DRAWING. BIM IS A BUILDING DESIGN METHODOLOGY CHARACTERIZED BY THE CREATION AND USE OF COORDINATED, INTERNALLY CONSISTENT COMPUTABLE INFORMATION ABOUT A BUILDING PROJECT IN DESIGN AND CONSTRUCTION.

• RELIABLE DIGITAL REPRESENTATION

• HIGH-QUALITY CONSTRUCTION DOCUMENT PRODUCTION

• CONSTRUCTION PLANNING

• PERFORMANCE PREDICTIONS

• COST ESTIMATES

WHAT IS BIM

ESSENTIAL PARAMETER IN BIM

“X”AXIS “Y”AXIS

“Z”AXIS

BIM PLATFORM USES THE THIRD DIMENSION (ALONG “Z” AXIS) WHICH

ENHANCES OUR VISUALISATION IN 3D AND EASES THE COORDINATION EFFORT

IN AUTOCAD TWODIMENSION ALONG “X” AXIS AND “Z” AXIS ARE USED

THE STEPS INVOLVED:

1. THE STRUCTURE FOUNDATION MODEL SHOULD BE FREEZED BEFORE START OF PHE MODEL

1. IN CASE OF ANY CLASH, CAN BE RESOLVED BY CHANGING THE PIPE ROUTE, LOWERING THE PIPE DEPTH TO BELOW FOUNDATION ELEMENT(HUME), SLEEVES CAN ALSO BE PROVIDED AFTER DISCUSSION WITH THE STRUCTURAL ENGINEER

TWO ELEMENTS ARE INVOLVED HERE :

STRUCTURE

PHE

STEPS INVOLVED:

THE RCP LAYOUT IS TO BE FREEZEDTHE LOCATION OF THE FOLLOWING TO BE FIXED

2.DIFFUSER/GRILL LAYOUT BY HVAC

3.FIRE ALARM/SPRINKLER LAYOUT BY FIRE.
