What is BIM, and How does it impact the construction industry

Building Information Modeling, or BIM, is a game-changing process that is revolutionising the construction. BIM in construction is a 3D model-based process that enables all construction professionals to plan, design, construct, and handle buildings and infrastructure more efficiently.

 

 

The first BIM software that resembled modern BIM tools was introduced in the late 1980s and early 1990s. Autodesk Revit, one of the most well-known BIM software, was released in 2000. Since then, BIM software has evolved significantly, with numerous other companies developing their BIM tools and platforms.

In this blog, we’ll explore the role of BIM in the construction sector and its far-reaching implications for project management, cost reduction, and sustainability.

 

What is BIM or Building Information Modeling?

BIM, or Building Information Modeling, is a digital tool used in construction. It generates a 3D model of a building, showing its physical and functional features. This model helps architects, engineers, and builders work together more efficiently. 

It allows all stakeholders to plan, design, build, and manage buildings better. It also helps in reducing errors and saving time and money. The BIM model is like a shared knowledge resource that everyone involved in the building process can use to make informed decisions.

 

How can BIM help you?

Building Information Modeling (BIM) enhances construction projects by improving stakeholder collaboration, allowing for precise cost estimation, and offering detailed 3D visualisation for better design decisions. It aids in detecting potential clashes before construction, reduces rework, and provides a digital record for efficient facility management post-construction.

Benefits of BIM

 

 

Here are five benefits of Building Information Modeling in construction:

• It provides valuable data for building operations, maintenance, and renovations, supporting efficient facility management throughout the building’s lifecycle​
• It tools throughout all project phases ensure higher-quality builds by enabling better control over design and construction decisions.
• BIM can assist in analysing and optimising buildings’ energy performance and sustainability, contributing to greener construction practices​.
• It enables more effective project management by providing a comprehensive and integrated platform for tracking progress, managing resources, and making informed decisions.
• BIM enables model-based cost estimation, leading to more accurate budgeting and cost management throughout the project lifecycle​.

 

What are the BIM standards?

BIM standards are consensus-based guidelines defining the methods and best practices for using Building Information Modeling in constructing and managing built assets. The National BIM Standard-United States is an example of such a standard, providing a framework for collaboration and data exchange among all parties involved in the built environment. It encompasses existing standards, documentation of information exchanges, and best business practices​ (National BIM Standard)​​ (National Institute of Building Sciences)​.

 

What are BIM dimensions?

 

 

BIM dimensions refer to the different aspects of information that can be incorporated into a BIM model. These dimensions typically include:

• 3D: The basic geometric and spatial representation of the building.
• 4D: Adds the element of time, allowing for schedule and construction sequencing visualisation.
• 5D: Incorporates cost estimation and budget analysis, enabling real-time cost tracking.
• 6D: Focuses on sustainability and energy efficiency, helping in the analysis of a building’s environmental impact

 

What is a BIM object?

A Building Information Modeling object digitally represents a physical product or construction element within a BIM model. It contains detailed information, such as geometrical data, material properties, and functional characteristics, which can be used for various purposes, including visualisation, simulation, and analysis. BIM objects are essential components of a BIM model, enabling accurate and comprehensive representation of the building design.

 

From Blueprints to CAD to BIM

The transformation from blueprints to CAD to Building Information Modeling represents the evolution of architectural and engineering design. Blueprints, hand-drawn on paper, gave way to Computer-Aided Design (CAD), which allowed for digital 2D and 3D modeling. 

Building Information Modeling further advanced this by incorporating detailed building information, enabling better collaboration and efficiency throughout a building’s lifecycle. This progression reflects a shift towards more integrated and information-rich construction and building management​approaches.

 

BIM Objects

 

 

• Improved Project Visualisation: It allows for creating detailed 3D models, enabling better project visualisation and aiding in design decisions and client presentations​​.
• Clash Detection: It helps identify potential clashes between different building systems (e.g., structural, mechanical, electrical) before construction, reducing the need for rework​​.
• Facilities Management: It provides a digital record of building information that can be used for efficient maintenance and management of the facility post-construction
• Accurate Cost Estimation: It enables more precise cost estimation by providing detailed information about materials, labour, and other expenses, helping to reduce budget overruns​.

 

The “I” in BIM

The “I” in BIM stands for “Information.” It represents the crucial data and knowledge embedded within the Building Information Modeling process. This information encompasses all aspects of a building’s physical and functional characteristics and is used to support decision-making across the building’s lifecycle, from initial planning to construction and beyond.

 

How Is BIM Information Shared?

BIM information is shared through a Common Data Environment (CDE), a mutually accessible online space. This environment allows stakeholders to access and manage information models throughout every stage of a building’s life. The CDE ensures that all project information, whether in BIM environments or conventional data formats, is shared using a single collaborative data environment.

 

Importance of Building Information Modeling

Building Information Modeling (BIM) is important because it enables improved coordination among design and construction professionals. This leads to more accurate cost estimating, reduced need for change orders, fewer surprises during construction, and a better understanding of a building’s potential performance. 

BIM also improves facilities management after construction is complete, providing a digital record of building information that can be used for maintenance, space planning, and asset management​. 

 

How Does the BIM Process Work?

The BIM process involves creating a digital showcase of all a building’s characteristics through computer-aided design (CAD). This model is used for various purposes, such as construction planning, cost estimation, and facilities management. The BIM process results in a Building Information Model that contains details about every aspect of the building. This model improves accuracy, expresses design intent, transfers knowledge, reduces change orders, and provides insight into existing buildings for future projects​. 

 

What Can BIM Do?

 

 

Building Information Modeling can do various tasks, such as:

• Visualise and Analyse Building Designs: It allows for the creation of detailed 3D models that can be used to visualise and analyse building designs, facilitating better decision-making and design optimisation​​.
• Generate Construction Documents: It can automate the generation of construction documents, ensuring consistency and accuracy across all project documentation​​.
• Coordinate Work Among Professionals: It enables effective coordination among architects, engineers, and construction professionals, reducing conflicts and improving project outcomes​​.
• Create Virtual Walk-throughs: It models can create virtual walk-throughs of buildings, allowing stakeholders to explore the design and identify potential issues before construction​​.
• Estimate Costs More Accurately: By incorporating detailed information about materials, labour, and equipment, BIM can help estimate project costs more accurately, reducing the likelihood of budget overruns.​ 

 

What are BIM Levels?

Building Information Modeling Levels are a way to measure the adoption and integration of Building Information Modeling within construction projects and organisations. They indicate a project’s collaboration, digitalisation, and information management degree. There are various BIM levels, such as Level 0, Level 1, Level 3, and Level 4, 5, and 6 BIM.

Here’s a detailed explanation of the types of Building Information Modeling Levels:

Level 0 BIM: Paper-based drawings + zero collaboration

At level 0, BIM is not used. Drawings and documentation are created and managed in 2D formats, typically CAD software. Information is shared through paper or electronic prints.

Level 1: 2D construction drawings + 3D modeling

Level 1 involves using both 2D and 3D CAD systems, but not in a collaborative environment. 3D models are used primarily for visualisation but are not linked to any data. At this level, Information is managed and shared electronically.

Level 2: Teams work on their 3D models 

In the level 2 stage, different stakeholders create separate 3D models, but there is more collaboration between parties. A Common Data Environment (CDE) is used to share information and exchange Building Information Modeling data between parties in a standardised format, such as IFC (Industry Foundation Classes).

Level 3: Teams work with a shared 3D model

Level 3 represents the full integration of BIM throughout the project lifecycle. All parties work on a single, shared model stored in a central repository. Information is updated in real time, and changes are reflected across all model views. This level also includes the use of advanced technologies like 4D (time), 5D (cost), and 6D (sustainability) BIM.

Levels 4, 5, and 6: Adding in scheduling, cost, & sustainability information

At level 4, the Building Information Modeling process is optimised for greater efficiency and effectiveness. This involves using predictive analytics, machine learning, and other advanced technologies to optimise project outcomes.
