A lot is said about Parametric design. Who needs it and why? Whether BIM Building Information Modeling can be useful at any level of investment implementation – we ask Wojciech Jędrzejczak, Managing Director of Autodesk in Poland.
A few years ago, when Building Information Modeling – BIM tools such as Autodesk Revit appeared, their use was a revolution for most designers. It required a switch from 2D creation to a 3D building design. Like every change, it took some time for the designer to get used to the specificity of the new approach and to use its potential. But the benefits of the BIM are invaluable – it significantly improves the design and delivery efficiency of the investment, helping to meet market requirements while reducing costs and time. But the benefits of BIM are invaluable – it significantly increases the efficiency of designing and implementing investments, and helps to meet market requirements, while reducing costs and time. Its advantages are starting to be noticed by both multi-sector laboratories and smaller, specialist laboratories. Revit is a universal tool that works in all conditions and any project, regardless of its specificity and scope.
Design efficiency – why is it so important and what influences it?

– Work, based on integrated data, within a single digital model, benefits at every stage of the building creation process. It allows integration of all facility systems and verification and elimination of conflicts that could result in significant downtime at the construction site. It enables the analysis of the building’s behavior in real conditions already at the design stage, and in subsequent stages – the integration of schedules and cost modeling. Within one 3D model, architects and other members of the project team can simultaneously post information that will then be shared with investors and contractors. This creates a development framework for an integrated design environment.

Both design and building of facilities are team-based. BIM means transforming the way project teams work into an even more collaborative team of engineers and specialists in different fields. The McGraw Hill Construction report, published in the United States, shows that the use of BIM in construction projects is growing rapidly – 62% of users surveyed say they will use BIM in more than 30% of projects. 82% of advanced BIM users surveyed believe that BIM has a very positive impact on their productivity. It is important that the longer you use 3D modeling software, the more the tool gets in your eyes. What’s more, they’re beginning to see new opportunities. It is characteristic that as experience increases, the assessment of the benefits increases.
– These are first: Better team communication by visualizing the details of the design object, using the BIM for building works to make it easier to read the design plans, and finally – more time for what’s most important – design. Because BIM also means less effort to prepare documentation.
The BIM also facilitates the design of sustainable buildings with higher energy efficiency, better use of natural light than artificial lighting and optimized use of materials. This is a very important feature of solutions dedicated to BIM because as many as 77% of respondents admitted that they participated in projects containing “green” elements in their assumptions.
Also in Poland, more and more sustainable buildings are being built, which receive LEED, BREAM, and DGNB certificates, i.e. they are subject to multi-criteria assessment in terms of energy and environmental efficiency. The parametric building model, the creation of which is possible thanks to the Revit Platform, makes it much easier.
A parametric design is a “database” record of interconnected objects in the design, available from equal levels – it is a record in which each change is reflected in the entire structure. At the same time “database” means that it is a full record of relations between individual objects of the project, and not only data about their geometry and appearance. BIM significantly simplifies the design process itself by the possibility of testing many variants and diagrams in the virtual world to select the optimal variant, also in terms of the environment. Modeling and simulating reality in the digital world gives endless analytical possibilities, which have a huge impact on the understanding and popularization of environmentally friendly solutions.
Old design methods are far from being sufficient today, especially for large and technically complex projects, as well as for infrastructure and town planning. This is mentioned in the article “Building and infrastructure. A new challenge for designers of the 21st century ”, which I read with interest. Processes such as population migrations, projected communication development, or flood protection modeling problems require modern methods of simulating complex real-world processes. The Revit platform and AutoCAD Civil 3D meet this demand. Designing infrastructure, roads, municipal water and sewage networks or energy networks, earthworks, drainage works, flood simulation and floodplain modeling are just some of the areas of application of this tool. In conjunction with Autodesk Revit MEP for designing internal installations, Autodesk Navisworks – software for managing the investment process and numerous specialist applications, we get a very modern, efficient and effective engineering design tool. It is already widely used in the field of large projects. It’s time to make the Revit platform available also to small construction and design companies.
The benefits that BIM can bring to internal system engineers (plumbing, electrical, mechanical) are fully justified. The degree of mapping the reality in a project made with the use of the Revit platform is very high, what’s more, it allows introducing changes and clarifying details at every stage of the investment through easy communication with the architect, constructor and contractor. Working on one model allows you to use all the knowledge contained in the project (available even to subcontractors of individual installations) at any time. Therefore, avoiding installation collisions is much easier than with the traditional design method. But there are other benefits as well. For installers and contractors, the most important are:
