Classification of Key Elements of Construction Project Complexity from the Contractor Perspective

Contractors are facing an increasing degree of complexity in their construction projects. Due to inadequately prepared project plans, they have been suffering significant losses during the execution One key disadvantages such plans is that planning process, a mostly defined as linear rather than dynamic and complex process with high uncertainty. Therefore, contractor who phase should consider impact characteristics on its implementation according elements complexity. In this research, we therefore first made overview existing research related Based frequency occurrence surveys, paper singled out eight groups contractors be aware After that, based fifteen were classified for each group. The conducted among managers identified from contractor’s perspective. Thereby, classification associated determining perspective was performed. By properly analyzing flow phase, can more successful when objectives
