Abstract

With the development of society, there are more and more existing building renovation projects. According to the common construction safety problems, and based on the characteristics of the construction process of renovation project, this paper established a construction safety risk assessment model of renovation project based on entropy-unascertained measure theory. Firstly, the assessment index system was determined by risk identification and analysis. Secondly, the unascertained measure theory was applied to the construction safety risk assessment of renovation project, and the weight of each index was determined by the entropy weight method. Finally, taking the actual renovation projects as examples to calculate its safety risk grade, it is found that the assessment results of the model are basically consistent with the actual situation of the site by comparison. The research shows that the model can provide a new idea to quantitatively assess the construction safety risk of renovation project and provide a reliable basis for the management and control of the construction safety of existing building renovation project.

Highlights

With the development and progress of society, the construction industry has developed rapidly, and the treatment of old buildings has undergone great changes
The transformation and reuse of existing buildings has become a new way for the utilization of old buildings
The renovation of existing building has become the best way to deal with old buildings reasonably

Summary

Introduction

With the development and progress of society, the construction industry has developed rapidly, and the treatment of old buildings has undergone great changes. Old dormitory buildings, etc., were built for a long time, with inadequate supporting facilities, their functions can no longer meet the needs of modern people’s lives and work [1]. The Orsay Railway Station in the center of Paris was successfully transformed into the Orsay Museum, which achieved the functional change and exerted great value [3], and the “Silo Wharf” granary in Baltimore was regenerated into a complex of residential and commercial services, and has become a model of urban regeneration and a new landmark for Baltimore [4,5]. Western countries began to pay attention to the research on the protection and renovation of old buildings earlier, and developed rapidly, which provided powerful theoretical guidance for the later research of building renovation [6,7]
