Strategic Alignment
By applying the BIM method, the amount of different sources of information is reduced drastically following the principle of Single Source of Truth. This leads to fewer complications, reduction of execution time, increased productivity, improved cooperation, higher quality and lower costs. Since several technical disciplines (road, structures, equipment, etc.) are merged and coordinated in a CDE, the effects of each modification in each discipline become immediately visible. This improves interdisciplinary collaboration while reducing the number of errors and inconsistencies in all project phases. The information and data management is based on the specifications of PAS 1192 and ISO 19650.
Highlights
- Measurable added value through BIM in all project phases thanks to integrated project delivery involving client, designers, construction JV and O&M
- Collaborative development of project specifications for BIM uses and information requirements (EIR and BEP) throughout project lifecycle.
- Offcial pilot project of German Government to adopt and further develop national BIM standards based on an open BIM approach (native and IFC formats mandated) and ISO 19650
- 20 models from from 5 disciplines in 6 di´fferent authoring softwares with a total of over 137,000 IFC structural objects
- Intensive knowledge sharing with 16 lectures and 3 publications (1 peer reviewed)

Detailed description of the project
The German Federal Ministry of Transport and Digital Infrastructure (BMVI) selects certain pilot projects for the preparation and testing of BIM level 2 specified by the adoption plan for digital construction in Germany. Project availability model A 10/A 24 was found to be particularly suitable in this context for the area of BIM contract lines, since essential parts of the value chain of planning, construction and maintenance are delivered by a single integrated entity involving all relevant stakeholders. This legal entity is represented by "Havellandautobahn GmbH & Co. KG", a consortium of the Royal BAM Group and HABAU Hoch- und Tiefbaugesellschaft. This consortium consists of design and construction joint venture "A 10/A 24 Havellandautobahn" and operation and maintenance joint venture "Havellandautobahn Services GmbH & Co. KG". The BIM management is under the responsibility of Wayss & Freytag Ingenieurbau AG, operating company of the Royal BAM Group.
The A 10 and the A 24 between the Pankow motorway junction (AD) and the Neuruppin junction (AS) are among the most heavily trafficked routes in the capital region. They will be extended or renewed in less than five years of undergoing operation in order to cope with future traffic volumes. The contract section covers about 64.2 km, and the contractor will design, build, maintain, operate and partly finance the various construction measures over the 30-year contract period. The construction measures comprise approx. 58.8 km, of which 29.6 km are related to the extension of the A10 (six-lane extension) and 29.2 km to a fundamental renewal of the A24. The construction period is expected to last four and a half years.
The BIM contract section in the project comprises a construction section on the A 24 in the range of km 222+675 to km 228+175. The section has a length of 5500 m and includes a tank and service station as well as four engineering structures. The replacement of the bridge construction BW2 over the municipal road Kuhhorst - Linum is at km 226+104. The noise barrier extends from km 225+246 to km 225+511 and thus has a length of 265m. There are also two traffic sign crane arms to signal the extension to the tank and rest area. The Linumer Bruch North and South refuelling and service stations are located between km 224+660 and km 225+210.
Folliwing use cases have been implemented:
- Capture existing structures: 3D laser scans were used to capture existing surface and structures as point clouds, which served as a basis for further modeling.
- Creation of BIM models: The discipline models were developed within the specified framework according to BEP.
- Design and verification: A structural model was developed to integrate structural design into the BIM process.
- 2D plans derived from the 3D models : 2D plan documents were derived from the models and made available in the CDE for plan checks by the client.
- Also enhanced collaboration through implementation of managed CDE
- BIM coordination: Regular federation of the discipline models in a coordination model as bases for subsequent automated collision checks, systematic conflict resolution and efficient analysis of technical design aspects.
- Rendering and animation: The public relations work is supported by model-based visualization and animation.
- 4D-planning: The construction process is visualized by linking the activities of the schedule with the model.
- Construction progress control: The planned construction processes are compared with the actual construction progress.
- Machine control and plant automation using model based information.
- Billing and controlling: The semi-automatically model-based quantity calculation will be used for billing and controlling.
- Issue management on site: The defects are recorded, monitored and forwarded via a mobile application.
- Model-based safety measures: Visualizations support the identification of danger zones and counter measures.
- Visualization ZTV-function and conservation measures: At the transfer of the model the conservation measures can be displayed and located, as well as model-based visualization of the results based on ZTV-Ing StB.
- Model-based operation and maintenance management: The development of an integrated object- and model-based asset management tool (omAMT) is planned in collaboration with employer and software vendors.
Detailed description of openBIM on the project
Currently, there are almost no openBIM methods and standards for the implementation and application of BIM in infrastructure and civil engineering in Germany. This is reflected, among other things, using many different software solutions to meet the required performance of BIM. Although many software providers offer closed BIM solutions, these are usually not compatible with an openBIM approach in the project due to unsolved integration issues especially in infrastructure and civil engineering. However, the use of the data formats IFC2x3 and IFC4 (and CPIXML and LandXML), considering proxy elements, have improved efficiency (with small Adjustments).
All required use cases by the client could be implemented and are now carried out by the project team. The project team has also decided to implement further use cases out of self-interest.
The classifications of elements and components were implemented with a project- and business-specific model structure plan. The benefit of implementing classification was a better model management. It really helped to have a structured model while discussing it with the client and project team. Based on current guidelines, attribute groups, attribute and values have been developed.
Benefits from using openBIM
The use of BIM as integrated methodology demonstrates benefits in many ways in the project A 10 / A 24. In order to share information throughout the development of the design, construction, operation and maintenance phase between the various disciplines, in addition to the CDE, several openBIM standards are used. There are multiple advantages to using these standards that are well illustrated by the A10/A24 project.
In addition to barrier free exchange, the principle of "single source of truth" can also be applied thanks to consistent data transfer. The "Single Source of Truth" principle leads to better planning quality without fewer discrepancies. Whereas the exchange format leads to fewer complications in the workflow and thus increases productivity, reduces processing time and ultimately also leads to a reduction in unplanned costs.
The consistent use of data and integration of data from the various specialist planners in a CDE means that errors in design or in interdisciplinary coordination can be detected at an early stage. By avoiding such errors and improving communication, the quality of the planning and ultimately of the entire project is improved in the subsequent project phases.
"We were able to innovate using openBIM."
Improving the effectiveness of project team communication with the implementation of BIM based workflows in both the planning and execution phase.
Development of new information/data standards for BIM in German infrastructure based on ISO 19650 in regard of the CDE, model coordination and general project handling.
Cooperation with universities throughout Germany (Frankfurt, Berlin, Karlsruhe) and the following theses:
- Concept for model-based progress monitoring/reporting on the 4D model using the example of the pilot project Availability Model A 10/A 24
- Model-based visualization of bridge condition data with focus on bridge structures
- Improving Communication Eectiveness in Infrastructure Projects with BIM- Case Studies in the Planning and Execution Phase
"We were able to identify where we need openBIM to develop further."
The implementation of BIM should not be run in parallel to traditional project activities Due to the ambitious and innovative project setup there was and is a great need for a holistic change management to embed BIM in the project considering the variety of stakeholders involved. Everybody needs to understand the purpose and added value of this new way of working. At that, BIM does not run decoupled from conventional processes. Rather, it is understood as a new, supporting component of day-to-day business that complements existing roles, workflows, processes, and more. Only in this way new tools and methods of BIM can be used for increasing efficiency and quality assurance, e.g. provided for design coordinators, work preparators or site managers and used adding value to the project.
In summary, it can be stated that an essential aspect of the efficient use of BIM from the start of the project was a close cooperation between the contractor, designers, future operator, client and software vendors. Based on this collaboration the project-specific BIM goals and uses can be designed and executed successfully.
As a result, there is a need for powerful interfaces specifically for infrastructure and civil engineering that meet the requirements of the openBIM process (which with IFC4x3 and IFC 5 already in motion).
I agree to be contacted about the project BIM uses outside of this awards program.
