2 Great Real World BIM Case Studies: The BIM Construction Strategy

Building Information Modeling is like giving your building a digital brain before it even exists. As we can know and evaluate what are we going to do before finalization of the project. The most meticulous and promising approach of BIM technology has enabled us to complete a Building Construction project with nearly hundred percent efficiency.

2 great examples of the real-world BIM case studies are included in this article. Along with it, I have broken down construction phases in brief how they are strategized and completed using BIM technology.

Two Great Real-World BIM Case Studies

The shanghai Tower and the Crossrail Tunnel in London are two incredibly recognized construction structure projects in the world. These two BIM case studies of mega projects exemplify successfully how BIM technology can transform a large-scale construction process. Let’s see in brief how BIM actually works in practice.

Case Study 1: Shanghai Tower, China

The Shanghai Tower project is one of the most gigantic examples of BIM’s power. Completed in 2015, the Shanghai Tower is the tallest building in China and the second tallest in the world, standing at 632 meters with 128 floors. The tower features a unique design that minimizes heavy wind loads and incorporates sustainable technologies, including 270 wind turbines and a double-skin facade for energy efficiency.

BIM technology was integral from the project’s inception in 2008. Autodesk tools such as Revit and Navisworks were utilized for design, documentation, and coordination among various teams. This approach facilitated real-time collaboration, reduced construction costs by approximately 32%, with no clashes during construction. BIM also supported environmental analyses to optimize energy performance, ultimately earning the tower LEED Gold certification.

This 632-meter skyscraper faced numerous design and construction challenges:

• Challenge: Complex twisted facade design
• BIM Solution: Used parametric modeling to optimize 20,000+ glass panels

Result: Reduced glass usage by 14%, saving $58 million in material costs

Case Study 2: Crossrail Tunnel, London

The Crossrail project, now known as the Elizabeth Line, is one of Europe’s largest infrastructure projects. It has been built to aim at improving transport connectivity across London and its surrounding areas. The project includes a 118-kilometer railway with 42 kilometers of new tunnels beneath central London.

BIM was crucial for managing the complexity of this massive project. It enabled effective collaboration among multiple stakeholders, including engineers, architects, and contractors. The use of BIM allowed for detailed planning and visualization of the tunnel alignments and station designs, which helped to identify potential issues early in the design phase.

Europe’s largest construction project demonstrates BIM’s value in infrastructure:

• Challenge: Coordinating 40+ contractors in dense urban environment.
  
• BIM Solution: Centralized 3D model sharing and clash detection.
  
• Result: Prevented 40,000+ clashes, estimated savings of £110 million

Building Information Modeling [BIM]: More Than Just 3D Models

BIM is your building’s digital twin, containing every single detail from the foundation up to the last roof tile before constructions starts. Including 3D physical modeling, BIM also facilitates with time-schedules, cost calculation and facility management details. And the way it brings the different dimensions of information in one platform actually makes BIM very special:

• 3D: The Physical Model
  BIM 3D represents the spatial geometry and physical attributes of a structure, allowing for visualization and analysis of design elements in three dimensions. Instead of just 2D lines, the 3D intelligence can help with visualization, quantification, and simulation of design, construction, and other tasks related to the building process.
  
  
• 4D: Time-related Information
  4D BIM is “dimension” of schedule-related information, a dynamic approach that integrates the 3D model with a timeline to accelerate the schedules and project phases of construction, enhancing planning and coordination.
  
  
• 5D: Cost Data
  BIM 5D, another dimension of cost data information to the 3D model, combines the 3D model with cost estimates. This cost data includes schedules, prices, and quantities and estimates enabling real-time budget tracking and financial analysis throughout the project lifecycle.
  
  
• 6D: Facility Management Details
  Incorporates operational and maintenance data into the 3D BIM model, facilitating efficient facility management and lifecycle planning post-construction.
  The facility managers can access to use the data and information in the BIM model and improve their decision-making.
   
• 7D: Energy Efficiency Integration
  7D BIM is the latest advancement that enables to measure and track the reduced energy consumption of the project lifecycle. In terms of functional and economic factors, a building’s design can easily be assessed. It speeds up decision making of the stakeholders for the selection of the components.

Implementation of BIM Strategy

The importance of BIM Strategy in construction building is so vast. You can know more about the BIM process and Revit software by studying our blog post on Building Information Modeling. So, once you’re convinced about BIM’s benefits and want to implement it in your organization. But before you dive headlong, let’s talk about how to do this right from thinking to implementation. Think of BIM implementation like training for a marathon—you need proper preparation, the right equipment, and a solid game plan.

Assessment: Know Where You Stand

First things first—evaluate your current situation. Ask yourself:

1. What’s your current workflow like?
2. What technology are you already using?
3. How tech-savvy is your team?
4. What resources can you allocate to this transition?

Planning: Setting the Stage

Now comes the crucial part—creating your BIM execution plan. This isn’t just another document to file away; it’s your roadmap to success. You’ll need to:

1. Develop standards that everyone will follow
2. Create a training program for your team
3. Choose a pilot project
4. Set realistic milestones

BIM Workflow Integration

Following the research and reliable sources given below, experts segregate the entire construction process into three consecutive phases.

Pre-construction Phase:

Apart from the basic hypothetical overview, pre-construction stage is divided into two phases. During this stage virtual design in BIM reviews let you spot potential issues before they become expensive problems. The system automatically detects clashes—like when a ventilation duct is designed to run through a structural beam. This clash detection alone can save thousands in potential rework costs.

Cost estimation becomes more accurate too. The model knows exactly how much material you’ll need, down to the last bolt. And with 4D scheduling capabilities, you can literally watch your project being built on screen, optimizing the construction sequence before breaking ground. Let’s see in brief how BIM facilitates the pre-construction planning

Phase 1: Design Development

1. Architectural Modeling

• Create basic building geometry
• Define spatial relationships
• Establish building orientation

 Time saved: 20-30% compared to traditional methods

2. Engineering Integration

• Structural system modeling
• MEP systems routing
• Performance analysis

   Clash reduction: 50-60% fewer conflicts

Phase 2: Construction Documentation

1. Drawing Production

• Automated sheet creation
• Detail library development
• Specification integration

   Time saved: 40-50% in documentation phase

2. Quantity Takeoff

• Automated material quantities
• Cost database integration
• Change order tracking

   Accuracy improvement: 80-90% reduced estimation errors

During Construction: Real-time Intelligence

Once construction begins, BIM really shows its worth. Project managers can track progress in real-time, comparing the actual site conditions with the virtual model. Need to know how many windows have been installed on the third floor? Just check the model. Wondering if the latest material delivery will fit in your designated storage area? BIM has the answer.

Safety planning becomes more proactive. By visualizing complex procedures before execution, teams can identify and mitigate risks early. It’s like having a safety officer with X-ray vision!

Virtual Design Reviews

• Reduced design errors by up to 40%
• Weekly collaborative sessions cut decision-making time by 90%
• Average cost savings of $17,000 per caught interference

Post-construction:

The post-construction phase represents a critical period for managing lifecycle costs effectively. Recent data indicates that a significant portion of a facility’s lifecycle costs is incurred after construction, emphasizing the importance of effective facility management (FM) practices.

Implementing robust information management practices, particularly through the use of BIM, can help mitigate financial losses associated with poor data access and interoperability issues.

Here are some key insights regarding post-construction costs and the role of Building Information Modeling (BIM) in mitigating these expenses:

Lifecycle Costs in Facility Management

01.  Lifecycle Cost Distribution: Research shows that approximately 70% to 85% of a facility’s total lifecycle cost occurs during the operation and maintenance (O&M) phase. This phase generally spans a long period, making it critical for effective cost management.

02. Financial Impact of Poor Information Management: Inadequate access to information and interoperability issues during the O&M phase can lead to substantial financial losses. It is estimated that the U.S. loses around $10 billion annually due to these challenges, highlighting the need for better data management strategies in FM.

03. Cost Increase Due to Poor Practices: Inefficient information management can increase operational costs by 5% to 20%, affecting both schedules and quality of FM services. A well-structured management plan is essential to reduce these costs and enhance overall facility performance.

The Solutions of BIM in Facility Management

 01.   The integration of BIM into FM processes can significantly reduce lifecycle costs by providing detailed information about building systems and components. BIM facilitates more informed decision-making regarding maintenance, repairs, and upgrades, ultimately enhancing operational efficiency.

02. As BIM becomes more standardized in the design and construction phases, its adoption in the O&M phase is expected to improve. BIM allows for better data availability, which is crucial for planning improvements and managing existing buildings effectively.

03. Utilizing BIM can help streamline information access for FM teams, reducing cognitive overload caused by excessive or poorly organized data. This leads to improved performance and efficiency in maintenance tasks.

• Collaboration skills (BIM is a team sport)

Project management capabilities (keeping everything on track)

What strategies can enhance BIM adoption?

It is easy to give solution but solving the barriers to BIM implementation is tough but not impossible.  As we can see from above, it is not a one-sided issue, it involves addressing multiple factors, including skills, budgets, and stakeholder engagement. From workers to clients, and through government laws and enforcement, each plays a critical role. In short, I will discuss practical solutions to enhance BIM adoption and improve its implementation across the construction industry:

1. Provision of Trial or Affordable BIM Tools: Offering trial versions or affordable BIM tools with easy interoperability, comparatively in the smaller companies, can help increase adoption.
   ​
2. Frequent Seminars, Workshops, and Training: Regular training sessions for company employees and industry stakeholders can improve BIM knowledge and skills.
    ​
3. Inclusion in Higher Education Curricula: Integrating BIM into higher education curricula can raise awareness and prepare future professionals.
    ​
4. Government Support: Government support might have an insignificant impact on especially for small and medium-sized enterprises.
   ​
5. National Standards or Guidelines: Establishing comprehensive and adaptive national standards or guidelines for BIM implementation can provide clear direction and reduce conflicts among stakeholders.

The Bottom Line

BIM is no longer a choice—it’s becoming a necessity in the construction industry. The strategic phases of construction describe above will help you to figure out the whole work process in the project planning. Therefore, start small, plan carefully, and remember that successful BIM implementation is a journey, not a destination. The technology will continue to evolve, and so should your approach to using it. Stay curious, keep learning. Good Luck.
