What is BIM software?

That’s a question that lately is attracting more and more attention to the construction industry. Interestingly enough, there are many different answers to it, as well. The truth is that Building Information Modeling is much more than a software solution, as it touches upon the way you organise your workflows, collaborate and interact with other project stakeholders.

In that sense, even if BIM is primarily promoted as a 3D model it covers a much wider spectrum of activities all relied on the unique value of the captured data. However, when it comes to BIM software the confusion is still there. To some extent, this has also to do with the fact that BIM has evolved a lot in the course of the last few years.

The big misconception, though, that BIM is all about the 3D model is still here. That is considered normal by many in the sector as it is easier to promote BIM as 3D modeling software than as a working process. After all, a user can’t buy the workflow. They have to set it up and roll it out across the entire organisation with the help of an open data ecosystem.

With that in mind, it becomes clear that the success of implementing and managing BIM in your organisation goes hand in hand with reinventing both your internal and external systems and processes.

We are referring to a major paradigm shift that requires a lot of work, brave initiatives and continuous effort to educate your team on the ways in which Building Information Modeling can improve their daily working routine and remove their admin and mental burden.

It goes without saying that data is in the core of this process. User adoption on-site will pave the way for a BIM-driven construction process where different stakeholders share their data and act on it in real-time.

Standard internal classifications equal success

Coming up with a standardised specification protocol for on-site follow up can really make a difference on the way you collaborate and build. Every organisation that starts its BIM journey needs to define and use one set of classifications.

Of course, defining this protocol goes hand in hand with the standardisation of your systems and processes. Every class of objects will be combined with a specific quality check that needs to be conducted across all projects.
So next time the field team will need to check if the doors in a building have been placed correctly, they can just go back to the protocol and see what’s the right way to go about it.

“What we are really hard working on is making sure that everything that has been done during the previous stage can be reused afterward,” explains Juan Nolet, BIM Manager at Besix.

That’s extremely helpful if we consider that most construction companies work simultaneously on a number of projects. In many cases, this means that they have different types of classifications, too. What they need, though, is a unified protocol containing a certain set of standard internal classifications so they can link their ERP system to them.

By mapping BIM object classes to specific planned tasks, checklists, forms and teams you ensure that processes are standardised and automated to ease the workflows on site. For instance, the Health and Safety flow will be defined in the beginning and run automatically to the entire project. And with every task completed and check performed field data flows back to the BIM model.

With that in mind, it becomes clear that construction companies need a platform that will enable them to easily map different classification systems consistently across project types and locations ensuring a uniformed data environment.

How BIM software can boost construction efficiency

By now it becomes clear that Building Information Modeling can have a transformative effect on construction and introduce higher standards of productivity.

This radical change is the result of working on a Common Data Environment (CDE) where all project participants can deposit their data and collaborate better. The increased visibility across the supply chain can lock misunderstandings out of the building process and increase operational efficiency.
In brief, here are a few of the ways BIM can improve construction efficiency:

Clash detection

The automation of the clash detection process can save your project both money and time. The virtual representation of the built structure allows project agents to remain one step ahead and prevent design conflicts before they emerge on site.
Thanks to Building Information Modeling, the resolution of design clashes and constructability issues can happen at an early stage and minimise the impact of a potential change on the project’s design and plan.

Information management

We have already referred to the importance of a Common Data Environment (CDE) and the value that it could bring to the management of a construction project. A BIM model contains a massive number of data as well as crucial information about every single area of the construction process ( eg. materials, furniture, mechanical equipment, etc).

“There is a huge information need on construction site about what they have to build and what is a result you’re working to. And so we would like to give an answer to that information need. And I think that’s BIM, BIM models. And it is a good solution for that. It’s, on the one hand, visual, strong product that people can see what they have to construct,” suggests Dieter Froyen, BIM Manager at Willemen.

And he adds:

“But it also gives all the information they need about the product performances, and material, and quantities. All that information need is answered by a good BIM model.”

Thanks to BIM, all these precious bits of information can be stored in one place and remain accessible by all the involved parties. This element establishes a communication flow between the different project agents and protects the building process from costly misunderstandings and schedule delays.

At this point, it becomes also evident that data hold a much more prominent role than the 3D geometry because of their value at various stages of the building life cycle.

4D time management

The fourth dimension of BIM is also known as construction sequencing. In general, it refers to the enrichment of the information model of a project with an additional row of scheduling data. In that way, stakeholders both in the office and the site can have a precise overview across tasks while staying one step ahead of any issues that could emerge.

In other words, 4D BIM facilitates the visualisation of each project stage and makes sure that construction activities are planned better.

The rise of 4D BIM should not be seen as a way to replace planners. To the contrary, they are still a decisive component of the project. The only difference is that now they can complete their job faster and with higher accuracy.

5D cost management

The fifth dimension of BIM is dedicated to cost management. 5D makes it possible for project agents to work in a centralised data environment from day one. This new working approach eliminates the possibility of having people working in an isolated environment and prevents misunderstandings and costly reworks.

5D BIM allows also the faster processing of automatically generated quantities. The connection of data with specific components within the BIM model allows estimators to improve cost control throughout the entire project. Additionally, project agents can rely on the model to continuously update cost reports as the project moves forward.

How to choose BIM Software?

But how do you choose the right BIM software for your needs?

Do you focus on specific features and custom-tailor your BIM solution to your AEC requirements? Do you leave anything out or do you need all of the aforementioned BIM functionalities? What if you don’t have in-house experts from all AEC disciplines? Do you start small and scale later?

This is a good moment to introduce BIM maturity levels.

BIM the concept revolves around the collaboration between a number of AEC professionals during a project’s lifecycle, and BIM maturity system serves to classify 4 different levels of their involvement in the project, and with that, the number of dimensions used in the process, from 3D to 8D:

  • 3D (visual) – project visualization
  • 4D (time) – planning and scheduling construction activities
  • 5D (cost) – estimating budget and tracking costs
  • 6D (operation) – operation and facility maintenance from construction to completion
  • 7D (sustainability) – estimating and reducing energy consumption
  • 8D (safety) – drawing emergency plans and preventing safety issues.

At the outdated BIM Level 0, the collaborative workflow practically doesn’t exist – this maturity level is essentially equated with 2D. BIM Level 1 introduces partial collaboration and allows the exchange of 2D and 3D information via an online CDE (Common Data Environment) repository.

In addition to 2D and 3D, BIM Level 3 adds 4D and 5D information, thus enabling AEC professionals from various disciplines to share common file formats and integrate their work into a unified model. However advanced, this is still not a “master” model that modern BIM aims to achieve.

The “master” model includes the remaining three dimensions as well and uses cloud computing to ensure seamless exchange, integration, and unification between different AEC disciplines. This is BIM Level 3, which is also known as Open BIM, iBIM, or the Holy Grail of the BIM concept.

In choosing BIM software, you’ll be choosing between Levels 1, 2 and 3.

Anything less than that doesn’t match the modern-day standard of BIM the concept.

The usual considerations of IT procurement, such are user experience and cost-effectiveness, won’t help you choose the best BIM software solution, and here’s why. Regardless of the level you choose, most BIM solutions are highly sophisticated, user-friendly, and beneficial to your budget.
These are the questions you need to ask instead:

  • Which exchange formats are supported by BIM software?
  • Which AEC features and tools does the solution include?
  • How many people can work on a project at the same time?
  • How many dimensions and maturity levels does it support?

Depending on your specific requirements and procurement budget, the answers to these questions should help you determine the best BIM software for your needs. By definition, it must include tools for digital construction and information management, so don’t settle for anything less.

BIM software: 3 steps to successful implementation

Once you have found the software that will help you introduce BIM to your organisation, it is time to focus on the implementation process. A common mistake we witness both in construction and other tech-related sectors is that companies try to roll out across all projects and departments from day one.

Trying to change your core systems and processes so radically in such a short time can be a disaster. That’s why it is highly recommended to put together a precise BIM implementation and management before you begin. In a nutshell, here are the three main steps you need to keep in mind

1. Focus on your problems, not on the technology

Before you fall for the “nice and shiny” elements of Building Information Modeling, it is of paramount importance to focus on the problems you want to solve instead of the digital tools per se.

In that manner, you will be able to detect the main sources of pain for your organisation, find the right software and put together a well-articulated plan of action. Simply put, before you go digital, you need to define what you are trying to solve through the digital transformation of your firm.

After all, you should never forget that data culture is decision-making. The consistent collection and analysis of data will enable project stakeholders to make accurate and fact-based decisions leaving no room for mistakes during the building process and paving the way for positive margins.

2. Start small

The introduction of BIM software to your business should be done with baby steps. Like that, you have time to fix any transition problems that might appear without them turning into a threat for the entire organisation.

Ideally, you should start by assigning this paradigm switch to a smaller department or group of stakeholders within your company. This team should consist of both people who have a tech background and representatives of the onsite personnel. The combination of the two sides will lead to the creation of a functional workflow that encourages user adoption while pushing for a strong digital shift.

Once your designated BIM task force has completed the first roll-out wave, it is time to expand the use of the new tools to the entire organisation. That’s the first step toward standardisation.

3. Standardise

The path to digital adoption goes through standardisation. By setting a well-defined framework of action, you can ensure that the different field teams will adopt the new way of working easier and faster.
That is one of the biggest challenges the construction industry battles against as Juan Nolet explains below:

“What we are now facing is really the challenge of making people adopting the same language. So the standardisation of data is for us the core of our collaboration around BIM. If I asked somebody on site to fill in a form that has no link to a BIM model, people will not see how integrated the procedure could be. And so the approach is not really relevant. Having the forms linked to our BIM data will enable us from a BIM perspective to directly access the information that has been collected on site.”

In that aspect, the centralisation of information with the help of an intuitive, yet simple-to-use, digital tool can really make a difference.

How to train employees to use BIM software

While communicating your needs to a BIM provider, it’s not a bad idea to ask them one more question – whether or not they provide a training program for new users. If the solution you’ve chosen is any good, it won’t be very hard to master. But BIM is still a complex concept.

The problem is, you cannot use software BIM without concept BIM.
You’ll still need to set up standards for the workflows, objects, and templates you’ll be using in your projects. Without everyone from the team on the same page, you won’t be able to achieve the quick, efficient, and frictionless multidisciplinary collaboration that was promised.

That said, you should have discipline-specific content libraries with model templates set up before the training begins. This will make the system onboarding much easier, help your team get used to the new system quicker, and reduce the number of resources you’ll spend during training.

As for the actual training, continual learning is key.
Professional associations, such as the Association of General Contractors of America, National Association of Homebuilders, and American Institute of Constructors can help you discover many authorized providers of continuing education for BIM the concept and BIM the technology.

eLearning programs are the best option for your AEC professionals, as they improve retention rates while reducing training times to a minimum. Bing designed with employed professionals in mind, webinars and online courses allow highly personalized and self-paced learning as well.

But when it comes to your BIM software specifics, nobody can train your staff better than the people who’ve built the tools. Because of this, available training programs and responsive technical support should be very high on your list of priorities when choosing your first BIM solution.

Final word

Finding the right BIM software solution for your organisation and by extension, your projects isn’t a walk in the park. Nevertheless, knowing the needs of your business and understanding what’s challenges your onsite personnel faces can help you make the right choice and prioritise user adoption.

To achieve that you have to stray away from the idea that BIM is all about the 3D model and start exploring the best way to collect, store and analyse the vast amount of data that is generated on the field.

Like that, you will ensure that your model reflects reality and that the conclusions coming out of it can be used in future projects. Without a doubt, that is the first step toward a data-driven and standardised construction industry.
