Looking back: The Beginnings of BIM and the Fear of Falling Behind
A little over 10 years ago, BIM began to gain importance in building planning. However, many wondered: What exactly is it? A method or a software? Many companies wanted to modernize their outdated workflows but lacked the knowledge to implement the methodology effectively. This knowledge gap led to a boom in consulting services. However, many of these well-paid consultants were opportunists who took advantage of the trend, offering expensive training programs that conveyed only superficial knowledge often leaving participants with more questions than answers. A great deal of money was invested in knowledge that ultimately failed the test of practical application.
These negative experiences often led to disappointment among affected companies, further increasing skepticism toward the necessary transformation.
"A GREAT DEAL OF MONEY WAS INVESTED IN SUPERFICIAL KNOWLEDGE THAT FAILED THE TEST OF REAL-WORLD APPLICATION."
On the other hand, there was also the fear of missing out on a significant market development — much like Nokia, that simply slept through the shift to smartphones. Many feared that not hopping on the BIM bandwagon would leave their company in the dust. Caught between skepticism and the pressure to innovate, many lost sight of the true goal of digitalization: modernizing their business model and ensuring long-term success through standardization and automation.
The Path of Early Adopters and the Software Dilemma
Those who engaged with BIM at the time had to make a choice: Should they lead the way or wait until the market sorted itself out? Some companies took the leap forward. Some were very successful, while others were less impressed with the immediate "Return on Investment". Nevertheless, these early adopters gained valuable experience, even if it was sometimes painful and costly.
Many used low-code environments like Dynamo to develop their own scripts to fill the gaps in the software solutions of the time. That way, processes were created that at least delivered some results. However, the more custom developments there were, the clearer it became: These had to be maintained over time. Often, the creation and upkeep of these solutions depended on individuals, and the departure or absence of those people could crash entire process structures.
Meanwhile, the software market was advancing rapidly, making many of the custom solutions obsolete. Companies that had waited were now able to make quicker progress with modern solutions. However, many early adopters stuck to their custom developments. The investment was already made, and the high effort involved caused hesitation in adopting newer technologies. This dilemma must be solved, and the improved conditions should be used to one's advantage. The big advantage of the "BIM pioneers" is still the process knowledge gained, which, alongside the software solution, is necessary for successful implementation. Many challenges had already been identified in practical application, and solution strategies had been developed.
A similar phenomenon can be seen today: topics like AI and Big Data spark enormous expectations. Many people are convinced that AI will drive technological progress on its own. The idea that BIM processes could one day be fully automated by AI sounds tempting but is hardly realistic. Waiting for that would waste valuable time and resources. Instead, it makes sense to focus on proven, practical solutions that are already available today and offer real value. Digitalization is not science fiction, but solid craftsmanship. With the right tools and clearly defined processes, it can already be successfully implemented and later enriched with meaningful AI applications.
Progress comes through continuous improvement — not by waiting for technological miracles.
Processes for the Successful Orchestration of BIM Factors
For a successful BIM implementation, five factors must be considered. We have stakeholders who model building data under certain conditions and with existing technology. Processes make it possible to create a functioning system from the aforementioned factors. This interplay can then be referred to as BIM. Let’s take a closer look at each of these factors:
Framework Conditions
It is often argued that BIM requires clear framework conditions to finally achieve widespread adoption. In addition to legal regulations, the revision of the HOAI is expected to contribute to this, as the additional effort must be appropriately compensated. However, this brings us back to the core of digitalization and a provocative question: If digitalization makes my business model future-proof and optimizes my processes, do I really need external incentives or separate compensation for it?
Many of our clients have already successfully implemented BIM, and for them, "special compensation" is no longer relevant. The question of whether the industry should continue waiting for perfect conditions can therefore be answered with a clear “No”! Instead, it is up to the stakeholders to take the initiative and critically examine existing processes.
Technology
Can’t I just buy BIM? Some software providers would immediately answer this question with a resounding “Yes,” but it’s not that simple. Even though we are now much closer to a “mainstream BIM product”, software alone won’t solve the problem —because BIM is not just software, it’s a methodology.
Still, the question remains: how can BIM be meaningfully integrated into the daily workflows of MEP planners? The answer is closely tied to choosing the right platform. And one thing quickly becomes clear: there is no universal solution. Instead, companies should consider their individual needs and, above all, prioritize flexibility. Adopting BIM doesn’t necessarily require switching to Autodesk Revit or implementing an advanced Common Data Environment (CDE). BIM processes can also be implemented using existing systems like AutoCAD, as long as they effectively support the BIM methodology.
While programs like Revit or AutoCAD provide a solid foundation, they are rarely sufficient on their own to meet the complex demands of everyday planning. Typically, additional tools and extensions are needed—customized to the specific needs of users and their individual applications. A comparison with operating systems illustrates this well: Windows provides essential functions, but for specialized tasks like graphic design, additional software is required to achieve high-quality results efficiently. While there is no “one-size-fits-all” solution, the combination of tools should be kept as streamlined as possible to minimize interface issues.
Likewise, the introduction of a CDE should not be an end in itself. Such an environment is beneficial when multiple stakeholders need to collaborate within a shared digital data space, but it is not mandatory for an initial successful BIM implementation.
"EVEN THOUGH WE ARE NOW MUCH CLOSER TO A 'MAINSTREAM BIM PRODUCT', SOFTWARE ALONE WILL NOT SOLVE THE ISSUE."
Stakeholders
A key factor for successfully implementing BIM lies with the stakeholders within a company. The question of how many BIM specialists are needed and what skills they should have is not just a matter of numbers but rather one of company culture. It is crucial that everyone understands the principles of BIM and can apply them in their respective roles. This means involving all employees —both the enthusiastic colleagues eager to work with the latest technologies and the more skeptical ones who simply want to do their job without dealing with "newfangled nonsense".
Of course, these role descriptions are simplified, as most people fall somewhere between these extremes. The challenge is to consider the different needs and perspectives:
- Fostering Enthusiasm: Employees who are passionate about new technologies should be actively supported. Giving them the freedom to explore innovative approaches can provide valuable long-term insights.
- Engaging Skeptical Employees: Employees who primarily focus on execution should be supported in their core tasks. It’s essential to reassure them that they can continue their usual work without having to fully immerse themselves in the BIM world. The right software solutions make it possible to work in a BIM-compliant manner without requiring an in-depth understanding of the underlying concepts. Clear processes and structured data frameworks ensure practical implementation (more on this in the next section).
There is no straightforward answer to the question of how many BIM specialists a company “really” needs. A complete focus of all employees on every BIM process is rarely beneficial, as it can distract from overall business goals. Instead, a well-balanced mix is crucial—one that takes into account the individual strengths and interests of team members.
IF WE WANT TO PRACTICE BIM, WE MUST ENSURE THAT EACH INDIVIDUAL PROCESS STEP IS PRACTICALLY SECURED.
The goal should be a workflow that allows skeptical employees to focus on their familiar tasks while enthusiastic team members drive new methods and processes forward. This balance not only fosters team acceptance but also promotes innovation and efficiency.
Data and Processes
The use of data is essential—but it’s not enough to simply collect it. Information must be processed in a way that allows it to be used effectively. Processes should not only be practical but also consider the entire value chain. In theory, many BIM processes seem almost perfect: The level of detail for models is precisely defined in model development matrices for each trade and project phase, overarching review processes are meant to ensure compliance with these guidelines, and new roles focus specifically on process and data quality. However, in practice, this often results in a frustrating trial-and-error approach.
A comparison with a candy factory illustrates the issue: Imagine that all work steps are arbitrary, and only at the end is it checked whether the final product meets minimum standards. Anything that doesn’t fit would have to be discarded or reworked—an economically irrational approach. The same applies to BIM: correcting errors only at the end is inefficient. Instead, each process step must be designed in a way that prevents errors from occurring in the first place.
The key lies in a cultural shift: moving from error correction to error prevention. However, this requires clear, user-friendly guidelines. Currently, these are often too complex and project-specific, leading to time-consuming correction loops for fully formatting data consistently and correctly. It’s no wonder, that some view BIM as a hindrance.
JUST IMAGINE IF YOUR ARCHITECT DELIVERED A RELIABLE MODEL THAT ALLOWS YOU TO SEAMLESSLY CARRY OUT THE MEP PLANNING
Effective BIM processes require clearly defined, easily accessible requirements that are directly integrated into the daily workflow. To achieve this, both the required data and the underlying rules must be digitally encoded in a machine-readable format. This allows software solutions to ensure that errors are detected and corrected during the creation phase.
A promising approach is the IDS standard from buildingSMART (Information Delivery Specification). With IDS, guidelines for information depth, data quality, and delivery time can be integrated into projects in a machine-readable format. The authoring software can compare all data directly with these guidelines and immediately indicate whether something is missing or incorrect. IDS thus serves as a checklist for data quality in BIM projects, minimizing correction loops and saving valuable time.
Just imagine if your architect reliably delivered a model on which you could seamlessly carry out the MEP planning. The architecture software would already check the model quality and notify you about any missing data or faulty modeling. On the other hand, you would be able to see immediately whether the model meets the requirements or not upon loading the file. A perfect example of the significant efficiency potential in BIM-compliant planning.
The foundation is already in place to define the requirements for our attributions, regardless of the software solutions used. For the LINEAR Software, we have long implemented the necessary mechanisms to digitally map information structures and validation rules within Autodesk Revit. We call this feature “Element Classes and Property Sets”.
The name may seem inconspicuous, but these tools, in combination, are a real game changer. With some administrative preparation, the LINEAR environment can be set up so that users can work easily and intuitively with an appropriate view of the model. This allows both the client's requirements and all other project-relevant data to be integrated into the authoring system. Missing information or format errors are reported directly or can be systematically checked before being handed over to the person requesting the information.
The integration of the IDS standard into this framework is already under development and will soon be integrated into LINEAR Solutions. If you would like to find out more about the possibilities of IDS in combination with LINEAR, read the article "IDS Workflow in LINEAR Solutions for Revit".
Practical Recommendations for Your BIM Start – Small Steps to Success
Starting with efficient BIM processes doesn't mean having to change everything all at once. What matters is to create the foundation for long-term success with small, targeted actions. Here are practical recommendations to make your start easier:
1) Planning in 3D
3D planning is a central building block for entering BIM. Our world is three-dimensional, and any reduction to two-dimensional representations creates room for interpretation that should be avoided. With 3D planning, you open up opportunities such as collision checks, slot and opening planning, and many other use cases that make your projects more efficient and accurate.
2) Choose the Right Tools for the Right Tasks
Not every software is suitable for every purpose. While Revit excels in terms of parametric work and collaborative processes, AutoCAD-based LINEAR solutions offer clear advantages for detailed construction planning, where collaboration and parametric geometries are less of a focus. Selecting the right tools is crucial for seamless integration into your workflow.
3) Beware of Overly Complex Solutions
Keep simplicity simple. If a technology raises more questions than it solves problems, caution is advised. Trends like AI or other innovations should only be implemented once their concrete added value is clear. Instead of being distracted by hype, focus on digitalization as the first step—it’s not a passing trend, but a necessary development.
4) Make Your Data Usable
An overloaded model is of little help. Keep your models as lean as possible, focusing on relevant information. Create structures that enable your computer to truly assist you. Structured classifications and clear attributions allow for precise quantity takeoffs, informed sustainability analyses, and a seamless transition to the operational phase. With validation rules, you ensure smooth collaboration with other project stakeholders.
5) Start Small and Grow with Your Experience
The most important step is to simply begin. Start with small steps, gain experience, and implement what works. Learn from mistakes and continuously optimize your processes.
BIM IS NOT ROCKET SCIENCE – BUT IT TAKES COURAGE TO TAKE THE FIRST STEP. WITH A TARGETED AND PRAGMATIC APPROACH, YOU CAN GRADUALLY UNLOCK THE BENEFITS OF THE BIM METHODOLOGY AND ACHIEVE LONG-TERM SUCCESS.
Optimistic About the Future
Digitalization opens up immense opportunities but requires a strategic approach to minimize potential risks. Being open to new ideas, the courage to implement innovative solutions, and a culture of collaboration are key success factors. With digital tools, processes can not only be made more efficient – they also create room for innovation and transformative approaches.
The construction industry is at a turning point. Technological advancements and smart strategic decisions will determine how successful the industry will be in the coming decades. A clear focus on standards, innovation, and collaboration is crucial to overcoming current challenges and shaping a sustainable, digital future.
Today, more than ever, it is essential to carefully analyze the software landscape and take a closer look "under the hood" of providers. Only then can solutions be found that comprehensively reflect the current state of the art, support efficient processes, and enable the development of future-proof business models – without unnecessary additional effort.
