Correction

Due to a data processing error when compiling the WA100, KEO International Consultants was mistakenly omitted from our market sector rankings as well as the regional and specialisms tables. If the correct information that had been submitted had been included KEO International Consultants would have ranked 2nd in the Middle East region table, while in market sectors it would have ranked 5th for retail, 8th for masterplanning and 4th for infrastructure.  In addition, in the specialisms tables KEO International Consultants would have ranked 2nd for construction management, 4th for project management, 7th for planning and 5th for environment. Unfortunately, our error was corrected too late for the print and digital editions of the WA100. We apologise for the mistake.
