In London last week, FIDIC launched its Second Editions of the Red, Yellow and Silver Books. They are big, weighing in at almost a kilo each. The general conditions cover 106 pages with more than 50,000 words, over 50% longer than the 1999 forms. Many improvements have been made, addressing issues that have emerged since 1999. Fans of Dispute Boards will be pleased to see that all three books now have standing boards with more emphasis on dispute avoidance; and that appointment of DB members and enforcement of their decisions have been made easier. Disputes and Arbitration are now dealt with in a separate chapter 21. Here are the most interesting changes to the Yellow Book.
