Roh Bau Construction

Nov 21, 2025

Roh Bau Construction

Roh bau construction is the first phase of building construction and is considered the foundation for the entire project. It is also known as rough construction or skeleton construction. This phase of construction lays the foundation for the entire construction process and is crucial for ensuring the durability and stability of the final structure.

The word itself comes from the German words ˝roh˝ which means ˝raw˝ and ˝bau˝ which means building. So, raw construction.

Three Phases of Roh Bau Construction

There are three phases of roh bau construction: Low roh bau, medium roh bau and high roh bau.

In roh bau construction, the main focus is on building the frame or skeleton of the building. This includes the construction of walls, floors, roofs and all other major structural elements. This is done using various building materials, including concrete, steel and masonry, depending on the type of building being built according to local building codes.

Before starting work, it is necessary to secure a building permit due to possible penalties for illegal structures. After obtaining a building permit, the construction site should be secured and fenced off, so that workers or passers-by are not accidentally injured. The notice board in front of the construction site should also clearly state what exactly is being done, the name and type of the building, information about the building permit, and the number, date of issue and notification of the start of construction.

The first step is the low roh bau, or laying the foundation. This usually involves digging a trench and pouring a concrete foundation, reinforcement. This is done to ensure that the foundation is strong and stable, and to provide a solid foundation for the rest of the structure. Once the foundation has hardened, the next step is to begin building the walls and floor.

After the walls have been built and the floor poured, the roof is added. This construction is called high roh bau. Adding the roof is usually done using steel or wooden trusses, which are designed to support the weight of the roof. The roof is then covered with roofing materials, such as shingles or tiles, to provide a protective layer from the elements.

Installations During Construction

In addition to the main structural elements, there are a number of other tasks that need to be performed during the roh bau construction phase. For example, electrical and plumbing work must be completed in order for the building to be ready for the next phase of construction. This includes the installation of electrical installations, water pipes and heating, cooling and ventilation systems. It is also during this phase of construction that PVC and aluminum joinery is installed on the building.

It is important to note that the roh bau phase of construction is the most demanding part of the process and requires the expertise of experienced and qualified professionals. This is because mistakes made during this phase can have a significant impact on the final structure. For example, if the foundation is not properly laid, the building may be unstable, or if the electrical or plumbing work is not done correctly, this can cause serious problems in the future.

The final stage of roh bau construction is called high roh bau. Once the existing structure has been completed and approved, the insulation of the building can be completed, and the walls are plastered and facaded.

At this stage, the building begins to take its final shape and it is now possible to get a clear idea of ​​what the finished product will look like.

So, the roh bau construction is an essential step in the construction process and requires a lot of skill and expertise to create a proper and usable property. The success of the entire project depends on the quality of the roh bau construction, so it is important to choose the right experts for the job. Whether you are building a new home, an office building or a large infrastructure project, make sure that the roh bau construction is carried out properly to ensure the success of the entire project.
