Abstract

Collaborative work in the construction industry has always been one of the problems solved by BIM (Building Information Modeling) technology. The integration of IFC (Industry Foundation Classes) data as a general building information standard is one of the indispensable functions in collaborative work. The most practical approach of merging IFC data depends on GUID (Global Universal Identifier) comparison at present. However, GUID is not stable in current applications and often changes when exported. The intact representation of relationships between IFC entities is an essential prerequisite for proper association of IFC entities in IFC mergence. This paper proposes a graph‐based method for IFC data merging. The IFC data are represented as a graphical data structure, which completely preserves the relationship between IFC entities. IFC mergence is accomplished by associating other data with an isomorphic graph that is obtained by mining the IFC graph. The feasibility of the method is proven by a program, and the method can ignore the impacts of GUID and other factors.

Highlights

  • Modern construction engineering often involves many specialties, and the construction process is complex [1, 2]

  • An IFC mergence tool is developed using C# in order to verify the feasibility of the method. e experimental plan is divided into two parts: one is that IFC files are merged under the same modeling software conditions, and another involves different modeling software conditions. e difference between the two parts is that the models in the same modeling environment are derived from the same software, and the IFC models in different modeling environments are derived from different software. e feasibility of the merging method is verified by comparing the count of IFC entities in the IFC model, which are merged by GUID and graph

  • Aiming at the problem of IFC mergence in information collaboration, this paper proposes a method for graph-based IFC data mergence. e graphs are established using the characteristics of IFC data, which are mined to obtain the maximum common subgraph. e mergence of the IFC graph is completed by this method of establishing the connection between IFC graph and common graph

Summary

Introduction

Modern construction engineering often involves many specialties, and the construction process is complex [1, 2]. With the development of BIM (Building Information Modeling), many researchers in the field of construction engineering utilize BIM to solve the problems in construction collaboration. It is a common method by which construction engineering participants acquire and store information through a BIM server or management system [4, 5]. A BIM server manages building information through uniform data format, and different participants share information through an integrated database of information of different specialties. It is easy to make mistakes when integrating the IFC entity by GUID and entities in the IFC model which are related to each other and their relationships are used to determine the same data in IFC mergence, which are not considered in existing tools and collaborative servers.
