Heritage projects 

Historical building renovation (Scan to BIM)

This is a small heritage building from the 18 th century. The model has been cut, in order to show the "purlin roof" structure and the vaults. The load-bearing walls are made of small solid brick. The ceiling height vary in each room. Currently the building is used as pub and it will be renovated. This building shown in the pictures is just a small part of a huge project.

The city council assigned a task to create a demolition plan for a small neighbourhood area in Eastern Hungarian city. The contarctor wanted to expand an existing store on this land. All the buildings were abandoned for a long time. The purpose of the 3d model was to assist sturctural engineers and designers to locate any load-bearing weakness. Fortunatelly, the beams were not bending downwards.

The client wanted to have LOD 300 model, with as-built sructural parts. The building itself is segmenteted into many different levels and idividual spaces. 

You can visit our 3d model below:  

Property details:

• The total area is 2500 sqm
• Average building material: small solid bricks, concrete, timber
• Location: city centre, mixed used area with abandoned buildings.
• Store expansion: some parts will be demolished
• renovated building: Blue colour, demolished: red colour 

Church renovation ( Scan to BIM )

This is a small countryside church from the 18 th century. The Floor plan is just 313 sqm and the height, measured at the spire is 36m. The BIM model has been created from point cloud data, in the purpose of roof structure renovation and heritage preservation.

The client's expectation was to build a high detail model, in order to execute facade restoration. Load-bearing structures were placed pecisely, following the point cloud. The bell tower in reality is slightly shifted, so the BIM model will show structural engineers, where to support the walls.

Building materials:

Load-bearing walls: Brick

Roof structure: oak, ceramic roof tile

Spire shell is covered with red copper

Facade: plastered and painted

Bell system: structural steel

Bell structural details:

The bell system, which has about 1,2 tons of weight, is supported by 3 "IPE 180" steel beams. They are embedded into the tower walls.

The roof structure is very complex and dense. It was a challenge for the survey team to provide enough details. We calculated the total volume of the roof timber structure, in order to have a clear picture of the load transmitted to the main walls. ( Total mass volume is about 86 m3. )

The model has some interior assets, such as chandelier and furnitures. In the bell-tower, the supporting steel structure is visible. Modeling the bell-system was important in structural point of view.

The shear mass of the bell movement, can cause extreme vibration. The slab and the "I-beams has to be in good condition. We can access the spire through timber stairs.

Historical Residential Complex (Scan to BIM) 

We were assigned to build a BIM model / Technical drawings from a Heritage building complex in the heart of a Hungarian city, from scanned point cloud data. These preservation projects requires some common tasks to deliver, such as detailed "facade" drawings and highlighted materials on the section cut drawings. The city council, have to maintain the original street-views and landmark elements. Keeping a uniform architectural-style in this neighbourhood was very important. 

This building has big ceiling heights, and the walls are made of small bricks and "adobe". ( This is a traditional natural building material used in the countryside ) The roof structure is complex, and are made of timber. The roof slab has timber structural elements as well. The building was packed with difficult vaulting methods.( Cloister vaults ) Modeling the final architectural details was a challenging task, due to foilage overgrown and decay.
