Abstract
Hazard-related data are a critical component in construction quality hazard management (CQHM). However, data security and latency issues in CQHM cannot be guaranteed in centralized systems currently and prevent it from achieving the goals of secure and efficient hazard analysis and further real-time quality process control. Focusing on these goals, a decentralized CQHM framework is proposed by introducing blockchain (BC) and deep learning (DL) technology. Moreover, considering the blockchain's limited storage capacity and block size, a deep learning-based multimodal storage strategy is designed with smart contracts and InterPlanetary File System (IPFS) for data lightweight. In accordance with the proposed framework, comparative experiments were conducted to demonstrate its feasibility by analyzing related metrics like accuracy, cost, and throughput. This study deepens the understanding of data security and latency issues in CQHM and offers technical guidance in establishing BC and DL solutions. Besides, the DL-based multimodal storage strategy provides a substantial data-driven advancement for lightweight on-chain data storage. Moreover, the proposed framework is promising to smooth the quality hazard analysis progress in improving on-site decision efficiency, promoting cooperation and standardizing quality process control.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
