HELLER develops guidelines for condition survey and assessment on voivodeship roads

At the end of 2018, HELLER Ingenieurgesellschaft mbH was commissioned by six Polish road authorities to develop the first guidelines, WDSN for short, defining the specific technical requirements for condition survey and assessment (ZEB) on Polish voivodeship roads. Prior to this, HELLER had already developed the DSN regulations for the ZEB on Polish national roads in 2013.

The condition survey and assessment always follows the same principles. Nevertheless, each road category places specific technical requirements on the ZEB procedure. For this reason, there also needs to be specific guidelines standardizing the procedure and helping road administrations to tender for survey and assessment services. Since such a set of rules existed only for national roads, six Polish road authorities commissioned HELLER Ingenieurgesellschaft mbH to develop a respective guideline for ZEB on voivodeship roads.

The new WDSN regulations - similar to the Polish DSN for national roads and the German ZTV ZEB-StB for federal roads - are based on raw data. They form the foundation for all further evaluations and ensure the comparability of ZEB processes for different road categories. The standardization of condition diagnostics on voivodeship roads and the comparability of this procedure with the ZEB on national roads will expand the market for survey and assessment services. This in turn leads to significantly lower survey costs. Moreover, access to reliable and up-to-date data on road condition enables more efficient maintenance strategies to be developed.

The guidelines have been prepared with active participation of the Road Administration of the Voivodeship Roads in Olsztyn, the Road Administration of the Voivodeship Roads in Gdańsk, the West Pomeranian Road Administration of the Voivodeship Roads in Koszalin, the Road Administration of the Voivodship Roads in Bydgoszcz, the Wielkopolska Road Administration of the Voivodship Roads in Poznań and the Road Administration of the Voivodship Roads in Białystok
