Johannesburg - Gautrain officials remained tight-lipped on Thursday about reports that water seepage is causing the project expensive delays.
Independent Newspapers reported on Tuesday that it could take 10 months and cost up to R100m to rectify seepage into a tunnel between the Johannesburg CBD and Rosebank.
A dispute resolution board ordered Gautrain constructors Bombela Concession Company (BCC) to do the remedial work, but there is still a disagreement between them and the Gautrain Management Agency (GMA) over who was responsible for fixing the issue, the report said.
GMA chief executive Jack van der Merwe reportedly said GMA was negotiating with the BCC and would make an announcement on Wednesday.
The remedial work involved digging 4 metre holes along the route to inject grout.
The preliminary plan estimated it would take three months to design the changes and another six to eight months to complete them.
GMA reportedly proposed a phased opening to allow the Gautrain to run between Rosebank and Pretoria, which would involve sealing off the Rosebank-Park station section.
The Bombela Operating Company (BOC), which will operate the completed railway, objected to a suggestion by the BCC that the route should be completely opened and that remedial work needed to be done after hours.
The route for the R28.1bn high speed train was set to open on June 28.
The GMA and BCC were not available for comment.
