Relationship between Management Challenges and Construction Project Sizes Using Fuzzy AHP

Residential building projects can be as simple as a single-story house or as complex as skyscrapers.How hard it is to manage these projects depends on how big they are.What aspects of projects get more challenging as they get bigger is still unknown.Thus, this paper delves into this subject and tries to identify these challenging factors in the emirate of Sharjah in the United Arab Emirates.To accomplish this goal, factors found in the literature were ranked by experts using the fuzzyanalytical hierarchal process (F-AHP).The identified factors were grouped into three categories.According to the F-AHP, technical challenges were the most challenging part of managing a large project.Interpersonal and operational factors came in second and third, respectively.First on the list of sub-factors was quality management, then the use of technologies.Surprisingly, the cost was ranked last.These results will help make it easier for decision-makers to match projects with project managers.
