Dear mr. Mahmoud,
Please can i know the difference between tge fidic red book 1999 and the harmonised MDB 2010?
Thank you in advance .

Dear Mr.Rash,

Red Book 1999 is a standard book prepared by FIDiC whereas MDB Hormonized 2010 is its revised Eddition based on the conditions of Red Book 1999 with some minor changes,being used on various Projects of ADB, World Bank and JICA etc.For example, In Red Book ,under Sub-clause3.5,there is notime specfied for the Engineer's determination whereas in IN 2010,there is a time frame of 28 daysfor the Engineer's determination.Similarly, in Red Book,there is DAB for dispute resolution whereas in MDB Hormonized 2010, there is DB for this purpose.We may say that Contracto'r rights are more protected in MDB Hormonised Version. Hope I have the answered.
