At the beginning of 2007 the Austrian contractor PORR was awarded with remediation works for a 48-km long part of the railway line from Campina to Predeal – part of the Trans European main Corridors TEN-T priority line 22 Bucurest – Brasov, connecting the southeast European countries with the heart of Europe.Due to partly new realignment and change of regular sections as well as protection against rockfall and slope slide a huge bunch of slope stabilization works became necessary, which were awarded to the contractor PORR and their designer IB-Brandner.Following the studies of the tender documents for the planned protection measures responsible managers of PORR decided to propose an alternative protection design by IB- Brandner. Changing the original design a more flexible and environmentally compatible solution consisting of high performance net, soil nailing and rockfall protection systems (fences) was elaborated and adapted to local needs. During design process, several critical areas were identified and additionally taken into account.In the paper examples of the design and erection process show how difficulties in implementation starting with the presentation of the idea continuing to the realization on site were managed and a technically more sophisticated and commercially competitive solution could be delivered to the customer Romanian Railway – case study.The European Commission awarded – following an election process in which all citizens of the EU could join - the remediation project Railway line Campina – Predeal in Romania as the environmentally best EU co-financed infrastructure project.
