Future-proofing Ystad Harbour

Ystad Harbour is one of Sweden’s largest ports, and has played a vital role in the development of south-east Skåne since the 13th century. The current port facility has been in use for an impressive 109 years. In 2018, Ystad Municipality began work on an expansion of the harbour, to allow port activities and ferry traffic to and from Ystad Harbour to be retained and expanded.

In connection with this extensive expansion, Sweco has been responsible for the digital modelling of all concrete structures in the project. The task was performed using 3D modelling in order to address the extremely complex geometric challenges associated with the port expansion.

3D modelling of the harbour’s concrete structures

The expansion of Ystad Harbour involves the establishment of new outer piers with prefabricated pier heads, a deployment area, a new central pier with ferry berths on each side and associated ramp systems and filling work. The project has been carried out as a turnkey contract, where we served as a consultant to contractor Per Aarsleff A/S.

Sweco modelled all concrete structures in the project using 3D modelling – much of this was even modelled parametrically. This means that the concrete geometry for the new structures and all rebar in the cast sections, concrete hammers, fender foundations, concrete ramp structures, bollard foundations, ramp foundations and the prefabricated pier heads have been modelled and can be viewed in a 3D model.

3D modelling ensures high level of detail

There are a number of advantages in 3D modelling concrete structures in projects of this type. The project plays out very differently than it would if each person involved had to interpret a 2D drawing that shows only part of the truth.

The parametric modelling has also made it possible to solve very complicated geometric challenges that can only be solved in 3D. The fender foundation on the outer corners of the pier provides a good example of this.

As part of our delivery, contractor Per Aarsleff was also given 3D models of each structure section and bar bending schedules, which they used in planning the execution of the project and when ordering rebar.

“The 3D models meant that we got off to a better start, and were able to see how the structures should be built. The level of detail in the 3D models was particularly useful during construction of the complex fender foundation. In general, the large amount of information and details in the 3D models have resulted in fewer questions and ambiguities, and we have been able to build a little faster and have seen fewer errors in the process. The models have also helped us optimise the rebar design, leading to a better overview of quantities and thus less material waste,” says VDC Coordinator and Planner Robertas Cerneckis from Per Aarsleff.
