RE:RE:News release agree. 15% contingency is very unusual and above the standard 10% that is placed into a budget going for FID (Final Investment Decision).
if i would have tried to place that amount in one of
my project budgets the executive committee would have torn me to shreds...LOL
any serious budget approved at this stage is typically class 2 (+/-10%); hence allowing for this tolerance in price fluctuation and also includes the 10% contingency in the breakdown.
i assume the KfW don't want to entertain any committees for these budget increases (keep the 100% success rate), so they simply increase the contingency...makes sense for a governmental bank.
