Modern construction projects can be designed, built and operated more efficiently and with higher quality when knowledge is shared quickly and transparently. With BIM.5D®, we have developed a new digital planning method for the construction sector, for STRABAG and for our clients that involves all project participants from the start, thus facilitating the interdisciplinary analysis of data and correlations and so increasing the possibility for early error detection.

Building Information Modelling is a model-based planning method to design, build and operate construction projects with the aim of optimising the transfer of knowledge, the quality of the result and the efficiency of the project participants.
All relevant data are digitally captured, combined and linked over the entire lifecycle of a construction project. The result is a comprehensible, transparent and resilient information network for all project participants.
BIM models provide a visual representation of how a project changes as it progresses, which materials are required in which quantities at what time, and what consequences could arise from late changes to the design.
On the basis of this multidimensional data model, BIM.5D® makes possible a level of security in terms of cost, design and scheduling that has never before been seen in the building and construction industry – and it does so at an early stage in the process. Missing information and conflicts beyond the individual trades and disciplines can be identified already in the design stage. This helps to avoid expensive construction errors and to plan improvements without impacting the scheduled construction time.

STRABAG has been advancing the vision of a “digital construction site” since the late 1990s. Over the years, BIM has been developed within the company under the name of BIM.5D® and has already been successfully implemented in several projects. The “5D” stands for the 3D model + time (4D) + process data (5D), thus adding all relevant process information to the product-oriented building information model. STRABAG is working with industry bodies to merge the company-specific variants of BIM into industry-wide standardisation initiatives.

Already during the design phase, geometric conflict analyses and virtual construction animations show to what extent the design and build considerations are ready for implementation or capable of improvement. In this way, most of the potential problems can be solved by comparing the knowledge of all project participants by means of the virtual model.
Here BIM.5D® stands out due to its many possibilities for end-to-end communication and for closing knowledge gaps to allow a new level of team, quality and cost certainty.
## TEXTBLOCK 6 ##
In the realisation phase, the digital process chains across all areas of work allow BIM.5D® to increase efficiency, transparency and cooperation, making it of enormous logistic support. Anyone can clearly see at any time how far a project has progressed, which material is required where and when, and how much something costs.
The same is true for scheduling certainty. BIM.5D® makes it possible to use the building data model to constantly visualise the scheduling and to review its plausibility in the process.
## TEXTBLOCK 7 ##
BIM.5D® also makes work easier during building operations. The virtual navigation offers efficient access to all information that is stored and linked within the model. Just 20 % of a building’s lifecycle costs accrue during construction. The remaining 80 % affect facility management. Using BIM.5D® here, however, requires first comparing the real object with its virtual representation. The use of laser scanning also helps to create building data models from already completed structures in order to take advantage of BIM.5D® in the operate phase.

New skills are needed.
An industry-changing innovation like BIM.5D® has an impact on the required qualifications. BIM.5D® will certainly not replace the regular construction site workers with robots. In the end, however, the changes will affect all positions and their job profiles. That also means that construction industry employers – and especially a leading company such as STRABAG – will be offering completely new development opportunities for potential employees.
BIM.5D® processes can only be carried out by people. STRABAG therefore offers training programmes in which employees learn the tools and necessary user skills for BIM.5D®.
## TEXTBLOCK 11 ##
The exact benefit of using BIM.5D® always depends on the specific requirements and conditions of the project at hand. STRABAG has therefore created a separate position to ensure the optimal, project-specific implementation of BIM.5D®: the BIM manager.
The BIM manager assists the design coordination and functions as a catalyst to optimise the workflow of the project participants by working out strategies – a “BIM Execution Plan” – for the coordination and implementation of the processes. This is done in coordination with the client and all project participants, of course.

## TEXTBLOCK 13 ##
An end-to-end digital project requires comprehensive, end-to-end leadership by a BIM manager.
The use of models for specific BIM services only makes sense if the necessary structuring and logical set-up of these models remains available for use in subsequent project phases. It is therefore of benefit to include the relevant project participants in the process as early as possible.
