Automatic Structural Method For Supporting Fire Protection Design Specification

With the help of computer and BIM technology,the BIM based automatic inspection system for the compliance of fire protection design and construction drawing can quickly,fully and accurately check design problems in the BIM model,which changes the traditional manual review mode and improves the review efficiency.Structuring code provisions,namely transforming architectural design code provisions described in natural language into a format that can be understood and executed by computers,is a key step in the establishment of BIM based automatic inspection system for the compliance of fire protection design and construction drawings.In recent years,China has made progress in the field of automatic review of drawing compliance,while structuring specification provisions has remained in the stage of manual processing or semi-automation.The manual extraction process is inefficient and error-prone,but the conversion of the manual processing process into an automatic structured process executed by the computer can greatly improve accuracy and efficiency.In particular,rules that can be understood and executed by the computer can be generated automatically after revising standard provisions.This thesis takes key points of fire control design review of construction engineering as the entry point and selects 16 commonly used fire control design specifications as the research basis.Firstly,specification clauses are preprocessed with the word segmentation system to make them into sentences containing only one design rule.Next,this thesis makes a syntactic analysis of the provisions of fire protection codes with the help of context-free grammar,and obtains the knowledge content that can be understood by the computer.After the morphemes of the smallest grammatical units are analyzed,nouns,modal words and comparative words are used to construct morpheme database with computer-understandable expressions.According to relations among verbs,the specification is divided into six categories.The structured rule formats and judgment basis of each category are derived,and the method library is also constructed.Finally,the automatic structured system for code provisions is developed and applied into case practice.The automatic structured method for code provisions has reduced artificial participation in processing code provisions,which provides a firm ground for building the BIM based automatic inspection system for the compliance of fire protection design and construction drawing.This method also provides the basis for establishing all kinds of construction drawing review system,which can help to ease work pressure,or inspectors and improve the efficiency of drawing review.Last but not least,the development of construction drawing review system can greatly improve the level of construction project management informationization.
