Renovating Historical Structures: The Benefits of using Scan to BIM services
Historical monuments are a remnant of the past that exists solely in written records. They tell tall tales of the grandeur and glory of civilisations and people long forgotten, and are a testament to the engineering and architectural skills of our ancestors. These monuments transcend their intended purpose, adopt a legacy, and become a cultural marker and object of pride for entire nations.
However, almost all of these monuments fall into disrepair with the ravages of time affecting even the grandest buildings. During such a situation, it becomes imperative to repair and renovate these buildings in a timely manner, to maintain them for posterity. And in the process of renovation, utilising Scan to BIM Services offers significant assistance that can streamline the renovation process.
What is Scan to BIM?
In a Scan to BIM procedure, a laser scanning device is used to obtain a precise 3D scan of a project’s real-world conditions. The scanned data is subsequently uploaded into a 3D modelling environment in order to generate accurate as-built models. The resulting model can then be used for designing, analysing progress, and assessing alternative courses of action.
Benefits of utilising point cloud to BIM for the renovation and restoration of historical buildings are numerous:
1. In the absence of building plans and sketches, the restoration or reconstruction of historic structures becomes extremely difficult. BIM Companies convert laser scans of a structure in its existing state into precise 3D BIM models.
The precise information and measurements of all building components contained within the BIM models reduces repetitive work and increases efficiency. It is possible to restore a building while preserving its architectural integrity and aesthetic value.
2. At times, due to structural failings, parts of historical monuments are often demolished and rebuilt. The renovation company must be exceedingly careful during this process for demolition may lead to further structural imbalances. Before demolishing any portion of a building or structure, surveyors or surveying companies must have in-depth knowledge of every crevice and cranny.
Frequently, the limitations of manual survey methods render it challenging to obtain precise data about a building’s structural components. Scan to BIM enhances the lucidity of how a portion of the structure will react during demolition analysis.
Using point cloud modelling for demolition, surveyors and surveying firms can visualise the structure and its surrounding areas after a portion of it has been demolished.
3. Existing roof frameworks and other structural components are precisely represented in 3D BIM models created with scanned data from inaccessible locations such as behind ceilings and above roofs and lofts.
The BIM model enables the project team to plan construction and renovation using data-driven decisions. In less time, they can design optimal support and scaffolding for the safety of employees and the rest of the building.
4. Scan to BIM provides surveying firms with a 360-degree view of a building or structure. 3D models and illustrations provide enhanced asset visualisation and spatial geometry mapping for a comprehensive view of the project space.
Moreover, granular visualisation enables BIM modellers to measure all visible elements in a scan and generate a precise 3D model.
Conclusion
Buildings and monuments built hundreds of years ago inevitably suffer wear and tear and would fall into disrepair if not maintained and renovated in a timely manner. Scan to BIM is an effective process that can be used in renovation for greater accuracy and efficiency. The onus of responsibility to preserve our culture and heritage lies on us.
