Image via WikipediaThe German company of Bilfinger Berger must have submitted a tender for the job concerning the trams in Edinburgh and by getting it they must have submitted the lowest tender so where is the problem. Did Edinburgh council not sign a foolproof contract safeguarding them from all this hassle or were they stupid enough to leave themselves wide open to this? This is another example of work being tendered for by a foreign company and although winning it, now wants to pile on extra costs before the work is completed. All these avenues should have been gone down and settled before this so if Bilfinger Berger are at fault SUE them and if Edinburgh Council are at fault pay up and learn by your mistakes. Sounds simple to me so just where IS the problem?
