During the construction of adjacent projects, it is necessary to detect, monitor, and evaluate the damage trend of existing buildings within the scope of construction impact. The complete detection, monitoring, and evaluation project for building damage trends is carried out in three stages: before adjacent construction, the current condition of surrounding buildings is inspected, including structural system investigation, damage condition detection, settlement deformation measurement, setting up settlement and crack monitoring points, issuing preliminary detection reports, and if necessary, analyzing the possible impact of adjacent construction on surrounding buildings, proposing settlement and crack monitoring alarm values, proposing construction plan improvement suggestions and monitoring requirements. During the construction period of adjacent projects, regular monitoring of settlement and crack monitoring points shall be conducted, and monitoring reports shall be submitted. If necessary, alarm and reinforcement measures shall be proposed. After the completion of adjacent construction projects, review and inspect the damage and settlement deformation of the buildings, analyze the impact of adjacent construction projects on the buildings, conduct structural testing and safety assessments if necessary, propose reinforcement measures, and submit a summary report of testing and monitoring.
