What is BIM?
Building information modeling (BIM) is a digitized platform to reinforce development by several tools, encompassing the creation of digital representations of buildings including the physical and the functional attributes. BIM utilizes the 3D, 4D, 5D, 6D, 7D and 8D modeling concepts, IT and software interoperability for designing, construction and operation of building projects.
Information can be extracted or exchanged from BIM files to support decision-making about a built asset. Contemporary BIM software applications can be used by individuals, businesses and government agencies to plan, design, construct, operate and maintain various physical infrastructures, like water, waste, energy, gas, communication utilities, and infrastructural facilities like railways, roads, bridges, ports, and tunnels.
What is BIM Scope in the Project Life-cycle?
Usage of Building Information Modeling (BIM) extends beyond the planning and design phase of the construction project, throughout the building life cycle. The subsidiary methods of building lifecycle management comprise of cost and construction management, project management, facility operation and application in green building.
How is Building Model Managed?
Building information models encompass the entire concept-to-occupation time-span. To ensure competent information management throughout this span, a BIM manager or a Virtual designer to a construction manager or a project manager is appointed. The BIM manager tracks the object-oriented Building Information Modeling from the pre-design phase to the stage of final-built against projected performance objectives. The model supports analysis, schedules, quantity take-off, logistics and more. AEC (Architectural, Engineering, and Construction) professionals are now developing BIM in various levels of details from LOD 100 to LOD 500.
How BIM Aids in Construction Management?
AEC project stakeholders in the construction process always face the challenge to deliver successful projects in spite of tight budgets, limited manpower, faster schedules, and incomplete or contradictory information. Disciplines like architectural, structural & MEP (Mechanical, Electrical & Plumbing) designs should be well synchronized, as two things can’t take place at the same place and time. Furthermore, BIM helps in identifying clashes and conflicts, specifying the exact location of discrepancies. BIM envisages the virtual construction of a facility before the actual construction, to minimize uncertainty, enhance safety, resolve problems, and simulate and analyze potential impacts. Sub-contractors can put information into the model before construction, with prospects to pre-fabricate systems off-site. Wastage can also be reduced and products can be delivered promptly instead of being stock-piled on construction site. Quantity and material extraction can also be done easily. Systems, assemblies, and sequences can be revealed virtually with an entire facility or group of facilities. BIM also minimizes errors through clash detection, where the computer model highlights the building parts (including a structural frame, pipes or ducts) that may wrongly intersect.
What is BIM Facility Management?
Building Information Modeling (BIM) helps construction professionals to bridge the information loss associated with managing a project from design & construction team to building owner & operator. BIM facilitates every construction project stakeholder to add and refer back every information acquired to BIM model. This yields advantages to the facility owner or operator. To take an instance, a building owner may find a leakage in the building. Instead of exploring the physical building, he can take a look at the model to check the location of the water valve in a suspected location. Dynamic information pertaining to the building, like sensor measurements as well as control signals from the building systems, can be integrated within BIM software application to support an analysis of building operation and maintenance. BIM can be utilized to support a holistic understanding and implementation of building management practices and “cost of ownership” principles that support the full product lifecycle of a building.
What is Green BIM?
Building Information Modeling (BIM) in green building or “green BIM” is a process of facilitating architects, engineers and construction professionals to increase sustainability in the construction industry. The technique helps all AEC professionals to integrate and analyze environmental issues in their design over the building lifecycle.

What is the Difference Between an Architect and a Contractor?
An architect blends artistic vision with practicality before creating a design. However, a contractor manages the construction of a building, designed by the architects. Contractors are needed to execute the vision in reality. They also appoint subcontractors and other construction workers for building the project.
Job Responsibilities of an Architect
- Assisting in selecting building materials based on code & design elements
- Negotiating contracts with contractors to appoint teams for the actual build
- Renovating old buildings to bring in compliance with code or restoring to design
- Considering planned building ensuring the best design
Job Responsibilities of Contractors
- Finishing jobs including roofing, flooring & electrical work
- Obtaining appropriate building permits from city and county
- Managing construction teams, ensuring the building is safe for inhabitants
- Using power-tools & instruments, like drills, hammers, etc. during construction
Why Permit is Necessary?
Permit Expediters work to restrict the number of rechecks by receiving the application and making accurate building plans from the beginning. They spend time determining the jurisdictions with the authority. You need a permit expediter as he acts as a consultant to make the process of permit application less confusing.
