Construction Risk Assessment for Old Town Renovation Based on AHP-LEC

Abstract

Old city renovation can improve the living environment and quality of residents and enhance the image of the city, and in the process of urbanisation, old city renovation is always a people’s livelihood project that cannot be ignored. This paper takes the old city renovation in County H as an example, through the combination of hierarchical analysis method (AHP) and construction safety evaluation method (LEC) in the renovation process, constructs the safety assessment model, uses the Delphi method to determine the factors that lead to the occurrence of safety accidents in the construction, assigns scores to each index and realises the quantitative analysis, and finally analyses the weighted size of the factors that lead to the occurrence of safety accidents and carries out the safety assessment. Based on the results of the safety assessment, it provides certain reference significance for the future transformation of the old city.
