The document summarizes a 3D laser scanning project of the National Museum of Romanian History in Bucharest, Romania. The museum, located in a historic building from the late 19th century, was scanned using laser scanning to create a detailed 3D model and documentation for rehabilitation purposes. Over 2400 scans were taken, producing a point cloud with high accuracy and detail of the building. Products delivered included a 3D model, 2D floor plans and sections, a BIM model, and 360-degree panoramic views for viewing the scans. The laser scanning provided an efficient, accurate, and non-invasive means to digitally document the building.

3D Laser Scanning
Project purpose: eBIM | 3D Model | 2D Survey
The National Museum of Romanian History is located in the historic
building also known as “The Post Palace”. Designed by the architect
Alexandru Savulescu in neoclassical style with German influences, the
edifice was built at the end of the 19th century.
The Post Palace becomes headquarters of the National Museum of
Romanian History in 1972 and is nowadays a historic monument. The
structure of the building was seriously damaged by the 1940 and 1977
earthquakes and is currently undergoing a rehabilitation process.
Therefore, it was decided that a detailed documentation of the building’s
current state was needed and the survey was carried out using the 3D
laser scanning method.
Advantages of the survey obtained through this innovative measurement technique,
supporting the rehabilitation project of the National Museum of Romanian History are:

What is BIM | eBIM ?
Building Information Modelling (BIM) is the process of building a 3D model which contains
parametric information about each element of a construction, including time and cost data. The
model can be used to make decisions during the whole life cycle of a building, from the design
stage to maintenance, preservation and rehabilitation works.
Existing Building Information (eBIM) provides a detailed and accurate 3D model of the current
stage of a construction made by processing the point cloud obtained from 3D laser scanning.
Detail level included in the 3D eBIM model:
- Visible structural elements (columns, beams, slabs);
- Exterior elements: exterior walls, roof;
- Partition elements: interior walls;
- Stairs, windows, doors;
- Sanitary fittings;
- Decorative architectural elements.
eBIM models can be generated in BIM software such as Autodesk Revit, Graphisoft ArchiCAD, RhinoBIM etc.
Advantages of the 3D eBIM model obtained from the 3D laser scanning:
Performing the 3D model faster, as compared to obtaining the model starting from the 2D survey;
High accuracy of the 3D model, as it is achieved by processing the point cloud obtained from the
3D laser scanning;
Complete documentation of the current state of the scanned building;
High level of detail of complex architectural, structural and installation elements;
The possibility of achieving accurate data about each building’s element, due to the parametric
3D eBIM model;
Full documentation provided to contractors, architects and engineers, enabling maintenance,
preservation and rehabilitation works.
3D LASER SCANNING
- larger amount of data
collected in a shorter period
of time;
- very low risk of occupational
accidents;
- non-invasive method of
data collection.
3D POINT CLOUD
- full and authentic 3D copy of
reality;
- the starting point for a complete
documentation of the building’s
current state;
- accuracy and high detail level of
the scanned object.
eBIM Model
- the delivered project is an
intelligent parametric 3D model;
- obtaining a detailed and accurate
model in a short time;
- enables a more efficient and
collaborative interaction between
the client, architect and engineer. Processing the 3D point cloud in Autodesk Revit - roof plan

other means or method of measurement;
The current state of the historical building can be thoroughly documented, based on the 3D
point cloud;
3D point clouds allow exact measurements of distances and areas and they represent the starting
point for the 2D survey and the 3D model.
