AI Technical Summary

Technical Problem

The fragmented and unified indexing of multi-source data during pre-construction housing development makes it difficult to identify and process the actual construction status, quantify and verify the progress status, and manage the project transparently.

Method used

Establish a unified index system with the unique identifier of the component as the primary key, link spatial range and time window, realize the accurate association between visual evidence, sensor evidence, document evidence and 4D BIM components, calculate the credibility index through the multi-source evidence quality assessment model, automatically update 4D BIM progress information, and provide natural language question answering service.

Benefits of technology

It enables refined assessment and transparent management of construction status, reduces human error, provides real-time and reliable progress benchmarks, supports rapid location and rectification, and improves project quality and trustworthiness.

Abstract

The invention discloses a transparent stage house construction management method and system based on multi-source evidence credibility evaluation in the technical field of constructional engineering. In future house construction, multi-source evidences such as a BIM model, a field image, Internet of Things data and a construction document coexist, but a unified credibility evaluation and conflict processing mechanism is lacked, so that different sources are likely to describe the same component or process inconsistently, and objectivity and traceability of checking and responsibility division are affected. According to the method, a credibility evaluation model containing evidence quality, aging attenuation and conflict measurement is constructed, the credibility index and the conflict degree of a component construction state are calculated, and the 4D BIM is driven to be automatically written back and updated. Meanwhile, the system realizes automatic progress deviation early warning, problem work order closed-loop management, and owner-oriented visual display and natural language question and answer service. According to the method, component-level precise management and control of the construction process are realized, the whole process is traceable, the progress information credibility and management efficiency are improved, the right of owners to know is effectively guaranteed, and the method has remarkable application value.
