The architecture, engineering and construction (AEC) sector has long been plagued with concerns like high costs, slow deliverables and lack of communication. This, in large part, can be attributed to a lack of efficient collaboration between the parties involved in a project, including architects, contractors, engineers, owners, designers and facilities managers.
This can be a costly concern. The National Institute of Standards and Testing (NIST) estimates that this lack of interoperability costs building owners $15.8 billion annually – equivalent to a loss of 23 cents per square foot of US property every year.
Advanced technology like building information modeling (BIM) is changing this by improving both the processes and technology involved in the construction process. BIM is an intelligent, 3D model-based tool that provides users with a digital representation of the physical and functional characteristics of a facility. This kind of representation allows for increased insight into the planning, design, construction and management of the space. When implemented correctly, BIM can solve construction’s communications concerns and provide a shared knowledge resource that can be used as a reliable basis for decisions during a building’s lifecycle.
Here is what you need to know about BIM and the importance of implementing it into your business.
Building Information Modeling: The Basics
What is Building Information Modeling?
Building information modeling, or BIM, is a building design technology that starts with the creation of an intelligent 3D model.
The most advanced BIM systems include a database of all related building information and intelligent data – including construction sequencing, cost and lifecycle management information – that allows for document management, collaboration and simulation throughout the lifecycle of a project.
The idea here is simple: if everyone involved can see exactly what a site is going to look like and have all relevant information available in one centralized, actionable repository, it can help the team:
- Explore design options
- Create visualizations that help stakeholders understand what the building will look like
- Develop the design documentation
Modern BIM systems do not just provide digital versions of physical plans – it provides a single source of truth from which all users can view, alter and improve upon those plans for smoother design, construction and operation.
The Importance of BIM Today
In many instances, BIM is no longer just a nice-to-have. According to the UN, the world’s population will be 9.7 billion by 2050. In this context, the global AEC industry must be more deliberate and efficient in their construction designs, creating spaces that meet the rising global demand and provide smarter, more efficient construction solutions.
To this end, more and more governments are actually mandating the use of BIM for public contracts, and an ever-increasing number of private clients are beginning to take note.
How Does the Process Work?
BIM can be used throughout a project lifecycle to bring clarity and efficiency into a building’s construction:
Planning: BIM can inform, guide and simplify project planning by allowing users to use reality capture and real-world data to understand how a building will really look in its natural environment.
Design: The design phase can be the most complex of any construction process, requiring conceptual design, analysis and extensive documentation. BIM data can provide comprehensive modeling that can organize construction and provide crucial information about a design’s performance. It can also inform logistics, simplify scheduling and ensure that all relevant personnel have access to the correct information throughout this process.
Construction: BIM specifications and shared documents can largely guide and simplify fabrication through this phase.
Operation: When it comes to operations and maintenance, BIM’s information-rich models and asset data can support operations, maintenance, refurbishment, extension and even demolition.
Specific Capabilities: What Can BIM Do?
Determine Building Project Specifications
With BIM, you can use spec modeling to write, manage and publish your project specification. You can import all relevant documentation from various data sources and personnel, thereby increasing collaboration and getting a more consolidated, accurate view of the complete project spec. Finally, structured templates can help also ensure compliance to corporate styles and previously-determined specifications.
Understand the Site and Design Possibilities
When it comes to a building’s environment and existing conditions, a lot can go unnoticed without visualization. Using BIM’s point clouds, digital photography and visualization capabilities, you can get a more complete understanding of existing features and surrounding structures. You can also use this data to further innovate and/or identify any shortcomings of your existing design.
Easily Manage Your Data
Using BIM’s preconfigured data templates and customizable data structure, you can ensure that you meet project requirements and that you can conduct effective analysis. You can also share up-to-date, complete data and documentation with all relevant personnel to optimize construction delivery and to streamline facility operations.
Get Comprehensive Building Design and Analysis Information
With your entire team working in one common environment, you can better coordinate building design and execution. Specifically, integrated information models and analysis allow for better engineering, design and asset performance predictions. This is particularly true if you integrate your BIM with your existing tools like your engineering document management (EDM) system.
Manage Deliverables from One Centralized Location
With BIM’s design model views, hyperlinks and drawings, you can ensure that drawing are up-to-date, that they accurately represent your design, and that the right people have all the engineering calculations, equipment documentation, and support they need to build and operate.
BIM: Tangible Big-Picture Benefits
More Efficient Project Delivery
Using BIM, you can generate production drawings and databases for manufacturing purposes. This ultimately allows for increased use of prefabrication and modular construction technology which can ultimately diminish waste, reduce labor and material costs and help sidestep common issues like:
- Poor coordination: With BIM, you can better coordinate contractors, designers, architects, and other relevant personnel.
- Clashes: You can also detect MEP, internal or external clashes before construction begins, thereby reducing delays, last-minute changes and the amount of rework required.
Better Management of Design Information
The beauty of BIM is that you can plan and visualize an upcoming project before you begin construction using 3D visualizations and space-use simulations. This means that all relevant parties can experience a space during preconstruction, which can reduce the number of delays, construction schedule setbacks or changes later on.
Additionally, the “database-first” modeling in BIM allows designers, construction teams, engineers and architects to access and edit relevant building information using their familiar graphical formats – all within one single dataset. This simplifies the editing process and prevents inconsistencies that arise when everyone accesses their own discrete files.
Overall, this visibility and collaboration leads to better productivity, more informed planning and an increased ability to explore design alternatives. For the building owners, this also can lead to increased asset lifecycle and lower cost of maintenance throughout a project lifecycle (learn more about how BIM benefits owners here).
Using a BIM, AEC organizations can streamline design and documentation processes and quickly update them based on new information, changes or new site conditions. They can also better plan and communicate schedules.
This can ultimately drastically reduce or eliminate construction schedule setbacks, helping ensure on-time or early project completion.
Clarity Amongst Stakeholders and Involved Parties
Digital BIM models allow for better coordination, analysis, data management and visualization between all relevant parties. This allows teams to share information, coordinate, plan, and update for complete inside and coordination.
Additionally, cloud capabilities of many BIM systems allow users to update information in real-time no matter where they are. That way, drawings and models can be viewed on-site and on mobile devices, thereby ensuring up-to-date access to project information at any time.
Increased Ability to Renovate and Retrofit Projects
By offering improved collaboration and increased access to relevant information, a BIM can allow experienced team members to work with builders, thereby providing better control and improved design execution.
Additionally, visualizations allow for better aesthetics and optimal construction decisions. This can ultimately both improve initial construction and allow for better renovations and retrofit projects.
Reduced Cost and Mitigated Risk
One study by McKinsey found that 75% of companies that have adopted BIM reported positive returns and on their investments. Specifically, costs can be reduced in the form of:
- Reductions in tender risk premiums
- Lower insurance costs
- Fewer variations
- Fewer opportunities for claims
- Reduced wasted and unused materials
- Reduced labor costs due to better documentation and communication
- Less outdated information
Safer Construction Sites
A BIM can also help you identify potential hazards and plan your on-site logistics before you actually begin construction. Additionally, a robust BIM offers visual risk analysis and safety evaluations. All of this can help avoid physical risks and ensure safety over the course of a project’s execution.
Using a BIM, you can avoid many AEC costs, including:
- Interoperability costs, including the cost of manual data entry and data duplication
- Delay costs like lost revenue and idled employees
- Operation and maintenance costs, like lower staff productivity and the cost of information verification.
You can also experience savings in FM with tenant charge backs and understanding what assets you have.
Connection to IoT and Advanced Analytics
Increased IoT Capabilities
By and large, the construction industry is woefully behind when it comes to IoT capabilities and advanced analytics. Indeed, while construction sites generate huge amounts of data, the vast majority of that information is not even recorded, let alone measured or analyzed for insight.
Advanced BIM technology can change this and bring IoT capabilities to a construction site. This could lead to many benefits, allowing for more efficient:
- Equipment monitoring and repair
- Inventory management and ordering
- Energy usage
- Safety protocols
- Quality assurance policies
Better digitization and data capture throughout the construction planning and design process has allowed firms to capture more information than ever before. The insights gained from this data can improve:
- Timeliness and construction progress
- Risk management
- Construction planning
Improved Maintenance of Regulations and Standards
Because BIM has shown such positive results and ROI, governments around the world have begun to mandate the use of BIM for public infrastructure projects. In the UK, for example, they mandate BIM level 2 on public projects, and you can see similar mandates In France, Germany, Finland, Spain and even the U.S.
It is important, then, for construction companies, engineers, designers and other relevant personnel to be aware of these regulations and able to comply.
