Study of Risk Evaluation for Complex Projects under BIM and IPD Collaborative Pattern Based on Neighborhood Rough Sets

Abstract

Faced with the existing problems in the construction industry, project managers have been aware that traditional project delivery patterns cannot satisfy the current building industry's pursuit of high-quality economic benefits or cope with the increasing volume and complexity of modern buildings. Therefore, whole-process comprehensive management has become a new development trend for engineering projects, the traditional project delivery pattern should be changed, and early-stage communication, cooperation, and information sharing among project participants should be strengthened. As for the BIM and IPD collaborative pattern, the emphasis is laid on collaboration among project members, and the core idea lies in benefit and risk sharing and full consideration of human resources, commercial structure and engineering system of projects. The advent of IPD pattern has well solved problematic issues encountered in engineering projects, where risk problem has attracted the highest attention. Risk factors of IPD projects were reduced and screened out based on attribute reduction theory of rough sets, and primary risk factors influencing smooth implementation of IPD projects were obtained.
