The US National Building Information Model Standard Project Committee has the following definition for BIM:
Building Information Modeling (BIM) is a digital representation of physical and functional characteristics of a facility. A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its lifecycle; defined as existing from earliest conception to demolition.

What is BIM used for?

The detailing of a building can be found in a BIM model. The model helps the stakeholders to understand what the building will look like before it’s built as well as it is used in analysis for exploring design options. The BIM model also serves the purpose of generating the design documentation for construction and creates visualization.

Our clients are interested in BIM for following reasons: –

• Improved visualization of physical and functional characteristics of a building
• Improved productivity due to easy retrieval of information
• Increased coordination of construction documents
• For detail and better estimation of raw materials for construction and tendering
• Multidisciplinary Collaboration for Better Insight
• Gain insights with analysis (Lighting/Energy Consumption/Structural Integrity)
• Experience the design before it’s built
• Future Operations and maintenance (Predictive maintenance/Asset tracking/Facilities Management)

Moreover, BIM not only allows design and construction teams to work more efficiently, but also it allows them to capture the data they create during the process. Captured data can be analyzed further and used in operational and maintenance activities. BIM data can also be used in planning and resourcing for a project both at city and country level. Therefore, the necessity BIMs are increasing across the globe.

Inputs we used for generating BIM model

• Point Cloud Data (.rcs, .rcp)
• 2D Drawings (.dwg, .dgn)
• Google Maps and Satellite Imageries
