Use of BIM in Construction

What is BIM?

BIM stands for Building Information Modeling. It is amongst the most recent advancements in the AEC industry. BIM technologies digitally build one or more detailed simulated versions of a building. In a virtual digital environment, BIM simulates the construction process. It digitally/virtually constructs a 3D representation of the original building called the BIM model. After completion, the Building Information Model has the accurate geometry and all the relevant data required for calculation, visualization, and other processes in various construction phases such as design, procurement, and manufacturing to realize the construction. It is important to note that BIM is not a specific software, but an environment or a process.

Autodesk REVIT

Autodesk REVIT is a 3D Modeling software. it implements the principles of BIM. It is the only complete parametric modeling software today. Its initial use was for architecture. Today engineers, architects, designers, and contractors use it too. It allows users to develop a 3D model of a building and structure, annotate it using the 2D drafting components, and access the building information from the building’s model database. Furthermore, it plans and tracks changes during various construction stages, such as planning, designing, executing, maintenance, and later demolishing. The software has three main disciplines:

1. Structure
2. Architecture
3. MEP

Applications of BIM

A BIM model serves several purposes, such as:

Visualization

It produces Three Dimensional renderings effectively and easily visualizes them.

Shop Drawings and Fabrications

Creating shop drawings for different structures can be complicated. It takes a shorter time to deliver shop drawings after creating the model.

Quantity and Cost Take-off

Building Information Modeling helps assess the cost of a project. If any changes occur in the model then material quantity is extracted and updated.

Sequencing of Construction

For all building components, It is effective to use BIM to organize material requests. Additionally, it is useful in making and delivering plans

Better creation quality

Above all, the quality of design and documentation is better and integrated.

Lifecycle Administration

In conclusion, all the information about the structural, electrical, and MEP components is available within the model throughout the project lifecycle.

Use of BIM in the Current Industry

Even though licensed/prominent architectural and design firms are understanding the concept of BIM, it has not been widely accepted for use as a design approach in less developed countries. In conclusion, architectural and design firms wanting to use BIM and Clients intending to gain accuracy and integration need to come to a compromise and agree to develop BIM in different stages and with varying levels of knowledge.

Practically, it is not encouraging to use modern tools on certain levels in developing countries. Many of the people involved with the industries are rather incapable of using it because they think that they are comfortable using the traditional methods. In other words, they think they are not compliant with new procedures, which causes a lack of coordination between different project stakeholders, eventually leading to project failure in cost and time constraints.

Benefits of BIM

Data Organization Benefits

BIM tools have empowered wide-ranging data. For example, BIM integrates construction data ranging from geometry, 3-D links, light examination, topographical information, material quantities, and various properties of the material of the product building components, description, fire rating, furniture, textures, costs, and total carbon content.

Technical Benefits

Computerized interpretation of both the practical and physical qualities of an office empowers clients to share design structure information with software applications, both within the association/department and in a multidisciplinary environment. Since data is stored in a BIM database, changes in the information during the planning process can be consistently monitored throughout the project.

Financial Benefits

There are significant financial advantages to BIM. For instance, BIM customers have outlined the benefits of using BIM. It significantly limits documentation errors, which have been tracked by using this as a business advertising device. Additionally, less staff turnover is observed as an advantage of using this process. Some long-term benefits are fewer legally binding cases and decreased cost of development.
