Abstract

This research studied external environmental factors that affect performance of construction contractors. Three categories of factors ,i.e., political factors, economical factors, and technological factors are considered. The external factors in this study were categorized into three groups according to level effects using cluster analysis technique. Questionnaire survey was adopted with 242 samples of experience personnel who have worked for construction contractor organizations at least 10 years. The result found that important factors effecting working performance of construction contractors are modern construction equipment, information technology, modern construction material, prefabricated technology, availability of construction labors, and overall political condition. The construction contractors can utilize this result in their adaptation to external changing situation.
