Spatial Risk Assessment and Geographic Information System based Approach for Construction Projects Risk Management

The construction of diverse civil projects is challenging owing to the numerous hazards involved. As a result, risk analysis is essential for civil project selection and construction work coordination. During the construction project planning and programming stages, risk analysis is viewed as the study of undesirable events. Construction risk is susceptibility to any potential loss. As the construction industry is essential to a country's economy, it is crucial to research and examine various risk detection and management strategies. We develop the model with a real-time case study to analyze the risk in construction projects in this paper. Risk is defined as an estimation of the likelihood, severity, and exposure of all risks associated with a construction stage. We propose the integrated approach for risk assessment in construction projects using the spatial risk assessment and Geographic Information System (GIS) techniques. We discover the different risks in construction projects from the literature review analysis to the design of the questionnaires. The proposed study records the responses from the various construction projects for prepared questionnaires. We present the National Highway 150 E of India case study to demonstrate the advantages of spatial risk assessment and a GIS-based approach. The outcomes of the proposed study reveal the major risks in construction projects. Therefore, our study recommends a generalized spatial risk assessment and a GIS-based method for various construction projects.
