Your advantages
BIM creates added value over the entire life cycle of a structure
Building Information Modeling is based on the continuous use of a digital building model over the entire life cycle of a structure, which extends from the initial idea, through planning and execution, to management and finally to deconstruction. By consistently considering all phases and the associated interfaces, information losses are avoided. Thus, the information content grows continuously in the course of the project. The central element here is a so-called Building Information Model (BIM model for short).
A Building Information Model is an object-based 3D model that, in addition to its three-dimensional geometric characteristics, also contains non-geometric additional information such as type information, technical properties or costs. Due to its structure, 2D plans can be derived from the BIM model, quantity lists can be output, simulations and calculations can be performed, and visualizations can be created. In addition, the BIM model can be used directly for facility management after construction.
BIM increases the quality of planning
During the planning phase, each specialist planner creates his own specialist model. By combining the individual specialist models, a so-called coordination model is created. This model is used to coordinate the individual specialist planners and to check for collisions between the trades. In this way, BIM increases cooperation between the specialist planners and makes it possible to identify and rectify planning errors in good time.
BIM improves collaboration
BIM also means the consistent digital management of 3D specialist models and documents within a common data environment (CDE). Both data exchange and communication between project participants take place within the common data environment. This means that all project participants have access to the latest data and information at all times.
With the help of BIM, deadlines and costs can be better met
The combination of a BIM model and a project plan makes it possible to visualize the construction process in time. This combination is called 4D-BIM. It shows when which component is to be erected on the construction site. This allows the project progress to be presented in a comprehensible way and possible conflicts during construction to be identified and prevented at an early stage.
In order not to lose sight of the costs, a 5D-BIM planning helps. In a 5D BIM model, the 4D BIM (3D + time) is supplemented by the cost component. In this way, the project costs can be predicted much more accurately. The effect of changes in the planning with regard to the costs can also be better calculated in this way.
The ordering process can also be optimized with BIM, since a 5D BIM model shows when which item is needed where. This prevents excess or unexpected costs from occurring.
Spectrum:
“Building Information Modeling (BIM )describes a cooperative working method, by which on the basis of digital models of a building, relevant information and data will be collected for its life cycle, maintained and exchanged in a transparent communication between the persons involved or will be transferred for further processing (BMVI, 2015).”
We, the Wuttke Ingenieure, can support you with our services in the preparation and planning of your project as well as during construction.
In the preparation, Oliver Wuttke, certified BIM Manager and CEO of the Wuttke Ingenieure GmbH, is on hand to offer advice. He will help you, among other things, in preparing the information request for the customer (AIA) or in the preparation of BIM liquidation plans (BAP). Beyond that, he can give you further advise on your BIM project.
In the construction phases, we can help you develop 3D models. We model on the basis of plans provided (“2D to BIM”) as well as on the basis of own measurements (“scan to BIM”). With the “scan to BIM – method”, we are able to draw upon more than 15 years of experience in the area of architectural surveying.
The following models can be created:
- architecture
- supporting structure
- building services (TGA)
- topography( 3D terrain models)
- infrastructure (BIM in civil engineering)
- civil engineering structures
During construction we are able to create a so called "as-built model” according to your wishes. The created model displays the actually built state of a building and allows for comparison of the planning (target-actual-comparison) and documentation. Our specialists are available for any questions and would be pleased to advise you on topic and gladly help you further. Therefore, please use the contact form.
Oliver Wuttke is managing partner of Wuttke Ingenieure GmbH and is intensively devoted with the topic Building Information Modeling (“BIM”) since 2015. As a surveyor, the focus of his work lies on the issue BIM concerning the existing building stock and the question, how to effectively create a 3D object-oriented model out of an existing building.
In the last years, his team was able to carry out numerous BIM-projects and gain practical experience. In a 10-day intensive advanced training course at the TUM School of Management he received the certificate “BIM professional” and successfully passed the exam “Basic Modul” of the Building Smart.
Due to his practical experience gained from numerous projects, he will competently advise you in all aspects concerning your BIM-project using the latest practical information.

We define scan-to-BIM as modeling of a continuance building on the basis of a precise measuring. This precise measuring happens with the help of a laser scanner. Here, the result is a geometric precise and photorealistic image of a building in the shape of a point cloud. On the basis of that point cloud, the following modeling will occur via Revit The result is an objectoriented 3D model, which displays the actual state and can be used for further planning. In addition, we offer you a point cloud viewer, by which you can easily view the result of the survey on your PC.
Our experts will gladly help you for any questions. Please use the contact form.
We take performance 2D-to-BIM to mean the creation of an objectoriented 3D model, on the basis of 2D plans. Thereby, we follow the clients’ specifications and either use the already existing component catalogue or create an own component catalogue according to the customer’ s requirements or the requirements for the model.

As-built documentation is defined as digitization of the actual state, which can be the final state of a building or a preliminary result during construction phases. The recording of intermediate results serves for the documentation, the accounting (quantity determination) and preservation of evidence.
Target/ actual- comparison – this comparison between the point cloud and model or the point cloud and state, makes it possible to effectively determine deviations.

Case Study
Project:
2D to BIM für Wolff & Müller
Development of a workflow that enables the effective creation of a BIM model from 2D planning.
-
Challenge
Wolff & Müller is an innovative construction company that has been working on the digitization of its processes for a long time. BIM is at the heart of its digitization strategy: Since the beginning of 2020, every building construction project in the shell construction phase has been handled with BIM. Wolff & Müller has defined various BIM use cases for the different phases of a construction project. For example, the company derives the material quantities for tendering and awarding the various trades from the building data model, creates automated schedules and simulates the construction process. The BIM method is also used to check the target/actual condition of the shell construction and to document defects.
In the bidding phase, Wolff & Müller usually only has 2D plan documents available. In the construction phase, too, there is often no BIM-based planning on the part of the client.
Consequently, the challenge for Wuttke Ingenieure was to develop a workflow that enables the effective creation of a BIM model from the 2D planning, according to Wolff + Müller's specifications. -
Solution
The level of development, i.e. the geometric degree of accuracy and the information content of the model elements, are defined at Wolff & Müller by a modeling guideline and a BIM information requirement guideline. In addition, a detailed component catalog already exists.
After the 2D planning has been sent to Wuttke Ingenieure, the two companies agree on the scope of the modeling at short notice and agree on a delivery date. Subsequently, the modeling is carried out in Revit according to the aforementioned specifications and with the help of the component catalog. In the next step, the BIM model is checked internally for compliance with the specifications. If the check is successful, delivery follows in IFC format and in native rvt format. Quality assurance also takes place at Wolff & Müller - it ensures that all planned use cases can be implemented with the model created. -
Result
The result is a BIM model according to Wolff & Müller's specifications that can be used for exact and automated quantity takeoff and cost determination as well as for construction process simulations and other use cases.
Conclusion:
Even if only 2D planning or no BIM-based planning is available, it is possible to create a BIM model that is suitable for different use cases. For this purpose, Wuttke Ingenieure transforms the 2D planning documents into a BIM model. Subsequently, the BIM model can be used for cost and quantity calculations, construction process simulations and information evaluations, among other things.
Wolff & Müller values both the quality of the models and the short-term service delivery in this cooperation. The result of this cooperation is the modeling of numerous structures of different types and sizes.
