Interscale Content Hub – The use of BIM for historical building renovations, or Historic Building Information Modeling (HBIM), offers significant benefits while addressing unique challenges inherent in preserving cultural heritage.
The detailed digital models created in BIM give us a complete picture of the building’s current state, which helps us make accurate assessments, make informed decisions, and plan renovations more efficiently.
But when it comes to renovating historic buildings, there are some unique challenges to consider.
These buildings often have intricate designs, complex geometries, and hidden structural issues.
Traditional methods might not be able to capture this complexity, which could lead to costly mistakes and delays.
So, let’s break down the details, shall we?
Benefits of Using BIM in Historical Preservation and Renovation
One of the main reasons to use BIM in historical preservation and renovation is how it can provide a lot of detailed documentation.
HBIM lets you create detailed 3D models of historical structures that include both geometric and semantic information.
This level of detail is essential for accurate restoration work. It ensures that every architectural detail is carefully recorded and preserved.
BIMPACT Designs says in their analysis, “The Role of BIM in Historical Preservation and Restoration Projects,” BIM technology lets you do precise 3D scanning and documentation of historical buildings, even of the tiniest architectural details.
Plus, HBIM makes it easier for everyone involved to work together. With a shared model, architects, engineers, conservators, and other professionals can access and update the model in real time.
This helps everyone to work together more effectively, which in turn means that the renovation project will be of a higher quality and more efficient.
Stanislav Vitasek’s paper, “The use of the BIM method for sustainable care of historic buildings: Methodological framework” shows how integrating data from different sources into a single BIM model makes managing buildings easier, especially when it comes to facility management.
BIM can also help with maintenance and management of historic buildings.
BIM lets you integrate different datasets, including material properties, structural conditions, and historical data. This helps you predict maintenance needs and plan future interventions more effectively.
Challenges in Renovating Historic Buildings
Renovating historical buildings is a whole different ball game than modern construction.
These challenges come from the need to keep historical buildings authentic and culturally significant while meeting modern safety and functionality standards.
In his paper, Vitasek goes over a few of these challenges, like the tricky stuff that comes up when you try to mix modern tech with the old-school preservation process.
One big challenge in renovating historic buildings is dealing with incomplete or fragmented historical data.
A lot of historical buildings don’t have much in the way of comprehensive documentation, which makes it tough to create accurate models.
BIM implementation means managing and interpreting these fragmented data sets to make sure the resulting models are reliable and useful for restoration purposes.
Another challenge is integrating BIM with traditional preservation methods. Preservationists often use established techniques and materials to maintain the historical integrity of buildings.
Finding the right balance between innovation and conservation is key to integrating these methods with modern BIM technology.
Vitasek says laser scanning and photogrammetry can make it tricky to make sure that digital models accurately reflect the historical and cultural value of buildings.
Also, historical buildings often have complex shapes and unique materials that are tough to document and replicate accurately.
Traditional 2D drawings might not show all the intricate details and irregularities of historical structures, which could lead to some inaccuracies in the renovation process.
BIM’s advanced modeling capabilities can help with this, but it requires special expertise and equipment, which can be costly and time-consuming.

Role of BIM in Historical Building Renovations
BIM helps create precise digital models with both geometric and non-geometric data. This thorough documentation is key for accurate restoration efforts.
BIM also makes it easy to create a detailed and structured documentation process. Techniques like laser scanning and photogrammetry are used to create super-accurate 3D models of existing structures.
These models capture the building’s exact geometry and current condition, which is really important for restoration.
For example, in Vitasek’s study, BIM was used to document the All Saints’ Church, making sure every architectural detail was recorded and kept safe.
BIM also integrates different types of data, including historical records, structural assessments, and material analyses.
This all-encompassing approach ensures that every aspect of the building is considered during the renovation, from its historical significance to its current structural state.
Then, think about how BIM helps us evaluate different renovation scenarios and their potential impact on the building’s integrity and heritage value by enabling simulations and analyses.
BIM technology lets you scan and document historical buildings in 3D with incredible precision, even capturing the tiniest architectural details.
BIM also helps people work together better. It gives everyone involved in the renovation process—architects, engineers, conservators, and so on—a single, shared model from which to work.

Tools and Technologies in BIM for Historical Renovations
Laser scanning is one of the most important technologies used in HBIM. It basically involves taking high-resolution, 3D data of the building’s exterior and interior through precise spatial measurements. This process turns the point cloud into a detailed 3D model.
For instance, in the renovation of All Saints’ Church, laser scanning was used to get precise measurements of the building and its condition, which were then used to create a detailed BIM model.
Another essential tool in HBIM is photogrammetry. This technique involves taking lots of detailed measurements from photographs, often taken by drones or airplanes.
The data is used to create a point cloud, which is then turned into a 3D model of the building. HBIM also includes semantic modeling, which adds metadata to the 3D model.
This metadata includes info about materials, historical significance, and structural conditions.
Ontologies and semantic technologies make the HBIM model even more useful. They let you search for and understand more about the building’s characteristics and history.
Vitasek’s article makes a great point about the importance of non-graphical information in HBIM. It gives us a better understanding of the building and helps us manage and preserve it more effectively.
BIMPACT Designs also points out that GIS integration with BIM is important. GIS helps us understand the relationship between historic structures and their surroundings by providing spatial context.
This integration helps to keep the building’s context in mind during renovation, ensuring that both the inside and outside of the building are considered.
