Across the world, BIM (Building Information Modeling) is a crucial and even mandated process to ensure
the planning, design, and construction of buildings is highly efficient and collaborative.
What is BIM?
BIM is an acronym for Building Information Modeling or Building Information Management. It is a highly
collaborative process that allows architects, engineers, real estate developers, contractors,
manufacturers, and other construction professionals to plan, design, and construct a structure or
building within one 3D model. BIM creates a digital representation and graphical database of physical
and functional characteristics of a project or asset.
Benefits of BIM
• Projects can move from Stage to Stage without losing data
• Quality of our designs will improve
• Projects will have less errors due to early findings (clash detection)
• Project Estimates will be more accurate
• Project Schedules will be more precise
From Blueprints to CAD to BIM:
In the past, blueprints and drawings were used to express information about a particular building plan.
This 2D approach made it very difficult to visualize dimensions and requirements. Next came CAD
(Computer Aided Design), which helped drafters see the benefit of plans in a digital environment. Later
on, CAD turned 3D, which brought more realistic visuals to blueprints. Now, BIM (Building Information
Modeling) is the standard— but it is much more than just a 3D model.
BIM objects, the components that make up a BIM model, are intelligent, have geometry, and store data.
If any element is changed, BIM software updates the model to reflect that change. This allows the model
to remain consistent and coordinated throughout the entire process so that structural engineers,
architects, MEP engineers, designers, project managers, and contractors can work in a more
BIM transforms digital collaboration in order to accelerate the construction process and even save
resources for a more sustainable planet. Ultimately, it’s about cost-optimizing the entire life cycle of a
building. “With BIM, we can detect errors such as collisions long before they reach the construction site.
This gives us better control over both costs and deadlines.
BIM IS NOT JUST 2D OR 3D…
You occasionally hear about 4D, 5D, 6D, and even 7D or 8D BIM.
>3D BIM is the three-dimensional digital building model.
>4D is the integration of a 3D model with a construction schedule inorder to visualize the sequence of
construction. 4D BIM adds time-related information and specifies both the duration of the project and
the construction schedule, so that all those involved in the various construction phases are kept in the
picture and can understand what is happening or should happen on the construction site. 4D models can
be created to various levels of detail, from staging analysis during the design, to detailed coordination
>5D BIM introduces factors such as the cost and quantity of materials, as well as their effect on the
> 6D building information modeling goes a step further by optimizing the final building management
based on sustainable criteria. >7D addresses the topic of facility management.
Why Do Companies Need BIM Management?
As that many dimensions can make things very complex and because computer-aided modeling still
requires people to provide and control information, it is necessary to coordinate the BIM project team.
This task is usually performed by a BIM manager trained for this purpose. The BIM manager defines the
workflow and monitors both the development stages and any existing guidelines. The role also includes
the maintenance, structuring, and management of the building data model as well as controlling the
A variety of BIM software is available Used primarily in construction industries to complement 3D design packages (such as Autodesk Revit, AutoCAD, and MicroStation)
>AUTOCAD helped drafters see the benefit of plans in a digital environment.
>NAVISWORKS allows users to open and combine 3D models; navigate around them in real-time.
>TEKLA STRUCTURES is used in the construction industry for steel and concrete detailing. The software enables users to create and manage 3D structural models in concrete or steel, and guides them through the process from concept to fabrication.
> REVIT is the primary source for BIM users along with Navisworks.
>SKETCHUP is also popular for coordination and clash detection

The BIM methodology, design investigation and development focusing on optimization via alternatives, are made at the time when changes are easy to implement. Thus, detailed assessments of; environmental, thermal, wind, shadow, visual bulk, and lifecycle cost, together with constructional and costing impacts of any design, arrive earlier in the design process, facilitating the benefits described. Authorities and industry partners should capitalize on the best practices and lessons learnt. Governments and authorities from a number of countries have taken this opportunity seriously, and are actively promoting the associated technologies and service providers. Most building owners, contractors, engineers and architects have a vision to improve one or more aspects of their existing business processes, which influence a projects; accuracy, consistency, integration, coordination and synchronization
