Abstract

This thesis discusses the main factors affecting Design and Documentation Quality in Construction Industry in Saudi Arabia. A survey of 21 contractors, 19 consultants and 14 owners from the Eastern Province was performed. The survey included 39 different factors affecting Design and Documentation Quality and their level of importance. The severity of those factors were measured by the level of importance and were ranked according to the importance index for consultants, contractors, owners and a combination of all respondents. A test for Correlation Agreement on the ranking of the factors between different project participants “consultants, contractors and owners” was also calculated using Spearman's and Kendall's techniques. It was found that the overall construction parties have moderate agreement on the ranking of important factors.
