my point was that despite all these difficulties, long duration and it being Switzerland, cost was actually reasonable. ~22M / tunnel kilometer is an order of magnitude lower than many other projects abroad. In general I find public infrastructure projects here to be well run and within reasonable budget. With these kinds of things, labour cost seems to be less of important than inefficiences due to administration and legal uncertainties (unions, nimbys etc.)
