What is the code for the formwork

BIM in practical use

PERI is currently planning the formwork and scaffolding solution for the construction of the Filstal Bridge on the Wendlingen - Ulm railway line. This bridge was defined by the Federal Ministry of Transport and Digital Infrastructure (BMVI) as one of four pilot projects in which the application of Building Information Modeling (BIM) is being tested and scientifically evaluated. This article describes some concrete BIM practical applications that PERI defines and carries out for this bridge in close cooperation with the construction consortium Max Bögl / Porr.

PERI sees BIM as the future leading planning standard and has been working intensively for several years on the possibilities and advantages of this working method. Because the seamless flow of information, the documentation of construction processes and access to constantly updated data for all project participants make a significant contribution to safe, efficient and legally secure construction, especially in large projects.

Previous PERI activities

The seamless flow of information within the PERI Group has always played an important role. What is meant by this is the time and location-independent access to all execution-relevant data and information so that they can be accessed at any time, e.g. B. can be processed in different PERI national companies. For this purpose, PERI developed and used its own project data management system, which has also been offered to external customers since the beginning of 2016: At bauma, the PERI IT experts presented the digital solution CENTRIO CLM (Construction Lifecycle Management), which contains all data and documents via the bundles the entire life cycle of a construction project in a structured form. This project data management system forms the basis for the BIM applications, so to speak, because the database contains, among other things, all 3D formwork models or information such as assembly instructions for the PERI systems.

For several years, a PERI team has also been working very intensively on the benefits and possibilities of BIM applications in formwork and scaffolding solutions. In various collaborations - including with construction companies and software providers - concepts and solutions are created for specific practical applications. Because only with such an approach can the necessary cooperation across company boundaries be realized.

PERI is also involved in the buildingSMART working group, which was formed by the GSV - the quality protection association for concrete formwork. In this working group, well-known providers of formwork and scaffolding systems and other industry participants develop, among other things, a BIM specialist model that defines overarching topics such as necessary interfaces and the like in a binding manner. This is intended to create a standardized exchange of data between the construction company and the formwork or scaffolding planner.

PERI is also a supporter of the BIM CLUSTER STUTTGART Initiative, which has set itself the goal of meeting the BIM-related challenges together with the BIM Task Group headed by the Minister for Transport and Digital Infrastructure, Alexander Dobrindt. Existing competencies are to be brought together and better brought to bear on a common platform through targeted campaigns. In regular, clearly structured meetings, as many interest groups as possible should jointly identify, discuss and initiate topics and actions. The cluster relies on voluntary work, is open to everyone and does not commit to anything. The initiative also awards the BIM Award annually in categories such as: “Special Prize”, “Research and Teaching”, “Processes” and “Special Project”. The award honors projects that demonstrate the added value and potential of the BIM method in digitally based cooperation and action in corporate cooperations or scientific networks.

The specific application at the Filstalbrücke

As part of a step-by-step plan, the Federal Ministry of Transport and Digital Infrastructure has named four pilot projects for the introduction of BIM in the area of ​​infrastructure construction. With these projects, the application of BIM is tested and scientifically evaluated. One of the pilot projects is the Filstal railway overpass. The construction project of the German Federal Railroad is being implemented as part of the new high-speed line Stuttgart - Wendlingen - Ulm; it is an approximately 485 m long railway overpass with two single-track bridges. With the maximum spanning height of 85 m, the Filstal Bridge will be the third highest bridge structure in Germany.

With the shell construction work currently underway, PERI is focusing on three possible applications:

  • quick access to the 3D formwork model as well as diverse, linked data and information,
  • the continuous documentation of some assembly processes using defined checklists and
  • the "Issue Management" as quick help for the construction site.

Using QR codes on the pre-assembled formwork and scaffolding units, construction site personnel can access a wide range of data linked to the physical product directly via tablet. This includes, for example, the production and assembly drawings as well as instructions for assembly and use. Furthermore, the position of the respective unit in the overall structure can also be visualized directly via the QR code. Advantages on the construction site include: Simplified, faster processes for logistics and on-site assembly. Access to instructions also speeds up work - without any additional organizational effort.

Working with checklists for defined work processes on the construction site is also particularly useful. For this purpose, processes such as moving the climbing formwork are broken down into individual work steps, which are then carried out by the person responsible on site and marked accordingly in the checklist. By "ticking" these work steps and confirming with a signature, the process described is documented at the same time - and can be found directly on the model at any time. This form of simple documentation and consistent information consequently reduces the risk potential and increases safety, and the quality of the construction work is also increased.

The “Issue Management” in the BIM model is used as a further, particularly quick aid for the construction site. The aim here is to quickly resolve issues, points to be clarified or even collisions with the respective project participants. For this purpose, a problem is digitally recorded on site on the construction site in the formwork model or on the associated drawing; Those responsible and other parties involved will be informed immediately about the open points. The solution that is then worked out is then explained and documented for everyone in the model. This high level of transparency and the fast and continuous information of all parties involved ensure considerable savings in effort and costs, and interface losses are also minimized in this way.

outlook

PERI sees the pilot project as a very special opportunity to implement diverse ideas and theoretical possibilities of the BIM methodology and the associated working method in further practical applications. The aim of the Federal Ministry is in particular to gather important experience for specific applications of the BIM methodology.
