Top Free and Open Source BIM Software Solutions
BIM the Commonplace Software of Tomorrow
The role of Building Information Modeling or the BIM software Solutions is approaching the forefront of the construction, architecture and engineering industry. More and more governmental institutions all over the world are emphasizing the positive impact of BIM software on building projects, and, by making the software as a necessary prerequisite for contract bidding, and the following venture commitments. As BIM software solutions are cost-effective, it is hugely promoted by the educational institutions thereby making it more popular among students. While there are many benefits of using BIM software, it can just be described as an efficient and cost-effective method to visualize, control and organize and communicate data about a building or construction project.
However, numerous software advocates do not need such advertisements as BIM tools are speaking well for themselves. The multiple advantages, driven by smart systems implementation, only prove the software’s necessity and lack of an equally effective alternative.
As per modern world trends, all industry niches are moving towards greater transparency and overall business efficiency. Although enterprises continue to raise their expectations from technological solutions, the existing software samples, surprisingly, keep up with ever-increasing demands. It seems like we’re only one step away from the global BIM adoption by both small and large companies.
Some of the best BIM software solutions are packed with highly powerful features that simplify many tasks, and there is a value in using it to transform your building project.
BIM is Not CAD
Rather than providing the helpful features of a computer-aided design (CAD), proper application of BIM tools saves funds, detects preventable mistakes, and creates accurate building schedules and speeds up overall construction activities. Basically, BIM software solutions help in enhancing building practices by minimizing the errors and contributing additional informational layers, such as information about existing materials, guidance on maintenance, correlation with other objects or models, cost and time estimations, analysis, and many others. No surprise, all kinds of modern constructions are built using BIM software.
An unexpected advantage comes from using these tools in dispute settling between stakeholders and contractors. They serve as a silent recorder of both the agreed-upon specifications and the factual operational report. Error detection can go wrong sometimes with human eyes; the BIM tool will always indicate whether there are grounds for debate. In addition, it significantly reduces courtroom time and any legal fees involved.
If the parties consider their cooperation mutually beneficial, BIM software can improve the results of their next ventures by accelerating the construction terms and conducting the analysis of their initial contract. By giving architects the ability to browse through the project from the concept stage and leverage the presented algorithms, it excludes faulty activities and creates an image based on their design preferences with all entailed characteristics. The anticipated risks derived from the given image help avoid otherwise probable construction or managerial mistakes, thus maximizing the quality of performance and outcome.
Nevertheless, many people still mistakenly consider BIM solutions a version of CAD software. To sort things out, first, we need to explain the main differences between these two solutions. Imagine a cube. In AutoCAD, the cube could be a box, a table, a cabinet, or many other things. The form itself cannot provide you with any insights on its practical meaning. At the same time, BIM enriches the images with certain properties and descriptive data. Once the information is made available, the system recognizes an object and its intended purpose and automatically provides standard field measurements, costs, and materials/textures. BIM software can accelerate overall construction operations by calculating the mass, type, and number of materials needed as well as their total cost. This way, a smart architectural workflow is built.
Most BIM software is developed for shared use by large teams composed of various professionals. The combined environment streamlines the communication practices of all team members and predicts the possible risks before they become apparent.
How to Choose BIM Software?
Although the benefits of BIM systems are numerous, they always depend on the software being used. The rational choice grants the best results; thus, one can never be too careful with market research. The first choice is always between the paid versions, and, free BIM software or open source BIM software. While some large companies are ready to invest in premium packages, others run with budget limitations and are keen on adopting the top free and open source BIM software solutions. As in every software niche, there are many options to select from, but you always need to consider your business needs and set feature priorities to make sure you don’t trade a queen for a pawn.
Keep in mind that free BIM software solutions may differ. Some products are entirely free of cost; others provide free licenses to students and academic institutions or free trials for a limited period. The intention behind free trials is to give you a feel of the product, and if you feel it suits your need, you can purchase them later.
Since there is no practical sense in describing the common general features of different BIM systems, we’d rather provide an overview of the most popular free and open source software.

BIM 360 streamlines document handling, project layout and review as well as serves as a sort of bug tracker for issue creation and resolution. Other useful integration capacities are presented by its combining with BuildingConnected bid board and Beck Technology estimation tool.
BIMserver is an open source platform that can be used as a BIM generator for creating new operating systems. Since the IFC open standard underlies the development of the BIMserver software, it can naturally deal with IFC data. Although you’ll need a certain programming level to use the platform’s advantages, the tool is easy to tune as it’s mostly built on plugins of an open framework; thus it’s free to use and adjust to your needs. You can either start your BIM tool from scratch or modify others to meet your project’s requirements.
Its primary functions topping the database include:
- Model review
- Models fusion
- Comparative analysis
- Versions storing

- Open BIM protocols
- Cloud facilities
This free software has originated from an architectural study, unlike other applications which stemmed from related engineering areas and eventually adjusted to meet architect needs.
The tool can be applied from the early design stages with no solid limitations to the user’s ideas. The modifications implied by the ground rules of construction will be added later when the initial idea is fully shaped. The preview option is available at any stage of modeling enabling the users to navigate through the sketch or zoom it if needed easily. The TAD BIM software supports the principles of object-oriented programming by inheriting the properties and procedures. The initial functionality can be significantly extended with add-ons written for any specific design using ARDELA language. Interestingly, TAD consumes the minimum resources possible with the common file size measured in Kilobytes.
Free CAD BIM
This is a free BIM toolkit developed for bringing about BIM practices and FreeCAD workflow. The original idea is in creating the multifunctional toolkit by gathering the best features important to BIM processes from different free utilities under one roof. The result is a convenient, intelligent workflow that can be easily adopted by both experienced ‘BIMers’ and newbies. The system’s own functions are few, mostly placed under the management bar. The ‘donated’ tools are classified by the categories: 2D sketching, 3D modeling, annotations, and modifiers.
This is not specifically a BIM product, but rather a task manager with certain useful BIM features that might come in handy. The created collaborative space for the involved engineering and construction teams enables fluent project data sharing, review, and comments from a desktop, mobile device or online from the website. A free plan is available for one personal project with up to five members and 10 GB of space.
Among the most practical features of Trimble Connect are the following:
- 3D markup, measuring tools
- Project initiation and handling with an extensive task manager functionality
