It has been already 10 years since BIM technology was used in the construction of venues for the Beijing Olympic Games.Although BIM technology has been vigorously promoted by the government and widely publicized by the industry, there were merely fewer than 5000 construction projects (about 6‰ of all projects) in 2018 adopted the BIM technology.Following the concept of business process reengineering, this paper reviews the development of BIM technology in construction industry by using OKR model and combing BIM technology from the source.At last, according to the review results, the direction and suggestions for further research on BIM technology are put forward for the future consideration and research.

Under the background of national "deleveraging" policy, all environmental protection projects need to adopt the PPP mode, which is require to carry out performance appraisal.Such performance appraisal needs to establish corresponding criteria for appraisal, and the information system will assist in implementing the performance appraisal.Based on business process reengineering, this paper establishes a KPI performance management, which is then used to develop performance management system.The system is applied in Erhai Lake Ring Pollution Interception Project to help the government improve its work efficiency.
