Research On Building Information Delivery Standards Supporting Construction Drawing Review Under BIM Environment

The carrier of architectural design information required for the review of routine construction drawings is two-dimensional CAD drawing.Due to the subjective judgments of plan reviewers,the large number of construction drawings,the low number of employees,and the high barriers to entry have caused problems such as heavy review,missing review,wrong review,and low efficiency in the current construction plan review.The Building Information Modeling(BIM)is by far the most successful combination of architectural engineering and information technology.The BIM collaborative design model has greatly improved the design efficiency and quality,and the design delivery results will gradually become BIM models.The use of the BIM model as a vehicle for reviewing building design information required for construction drawings will greatly improve the efficiency and accuracy of construction drawings review under the BIM environment.To ensure the completeness of the information required for construction drawing review is the premise and key factor to construction drawing review.Therefore,this paper proposes a study on the project information delivery standard supporting construction drawing review under the BIM environment.This article first analyzes the value of BIM in the review of construction drawings,and also points out the existing deficiencies and improvements,and then introduces the key technologies of construction drawings review in the BIM environment: building model preparation,rule interpretation,rule execution,and rule reporting,points out that "model preparation" focuses on the finesse of the model,and can use the LOD(Level of Development)standard to study the model's delivery criteria.Then,this article introduces the information delivery manual(IDM),which is the definition standard of BIM's process delivery requirements.It is to determine the specific information that needs to be exchanged for a specific process of a specific project.This article uses IDM to define the information delivery process for review of construction drawings.Then use the standard form to describe the delivery process in detail,determine the information delivery requirements for the review of construction drawings,and finally,with reference to the general provisions of the domestic delivery standards for design information delivery,propose standards for the delivery of engineering information supporting the review of construction drawings in the BIM environment and elaborates on the composition of the delivery standard.Finally,this article uses a project as an example to verify the delivery standards proposed in this paper.This standard also provides reference and reference for the formulation of relevant delivery standards,and it can also promote the extensive application of construction drawings review under the BIM environment.
