Since May, special civil engineering has been working on Dock 1 and 2 over a distance of 230 m. As a preparatory measure, the soldier pile shoring was constructed as slope protection for the working level of the diaphragm wall. In June, the north diaphragm wall work started at docks 1, 2 and 7. In addition, partial displacement bored piles were constructed at axes 1-44. After the first weeks of tireless work, an important milestone is coming up at the end of August: Special civil engineering handed over construction site 1 to structural engineering. This marked the start of the construction of the temporary structure, in particular the construction of the two abutments and the 44 bridge piers.
The inner-city infrastructure project demands shoulder to shoulder, passion and pioneering spirit from the construction site team. Extensive re-planning is necessary due to unknown pipelines in the ground. The top priority for the client in this complex project is to meet deadlines. While maintaining work safety, the team on site works hand in hand in special shifts to realise the customer's requirement.
BIM in action: More than just a 3D view
The BIM working method greatly enriches the cooperation between the ARGE partners and the client in the Südschnellweg project. In 3D modelling, the existing situation plays an important role in addition to the representation of the new construction parts. The model enables the team to identify collisions between planned and existing components as early as the work preparation stage and saves time during the construction process. The existing and new construction data combined into an overall model form an impressive coordination and communication tool. Even complex interrelationships can be communicated quickly and clearly to the many people involved in the project, which optimises the effectiveness of construction site meetings, among other things. By linking the components modelled in 3D with the processes of the schedule, the complex construction processes are vividly depicted in construction phase plans and the sequence is simulated like in a film. The 4D model created in this way makes it possible to depict the construction logistics and the required resources such as personnel, materials and equipment in relation to time and location. The 4D model can also be used to identify conflicts in the process at an early stage before construction begins. In a further step, the items of our bill of quantities are linked with the 3D model, resulting in a 5D model that allows quantities for the performance calculation on the deadline and at the end of construction, as well as the associated costs, to be determined and clearly displayed in relation to time and components. For the client, this means transparency and security all along the line.
