“…For the path results, it appears that the path obtained from Zhou's method 23 is rather an accurate one on topology than grid level. With slightly higher efficiency than Zhou's method, 23 our method can yield a shorter and more precise path. To further verify our accuracy, a stand-alone approach proposed by Lin et al 21 whose path is purely calculated with accurate grid cells is applied in our analysis.…”

“…Focusing more on navigation, they paid less attention to the accuracy of the path yet and mainly obtained their path from a mesh connecting randomly generated internal nodes. Noted the importance of path accuracy, a recent work from Zhou et al 23 constructed a topology graph with grid cell nodes in advance through a thinner operation. With the preprocessed topology graph and position information from its cell nodes, it returned an accurate and shortest path efficiently.…”

“…With an absence of the result from classical A star because of its higher value, we also find our result (average of 3.31 s) on data 7 being slightly better than Zhou's. 23 Despite our space partition, another explanation for this can be the determination of the grid resolution based on the characteristic of each space (see Equation ( 2)). For the path results, it appears that the path obtained from Zhou's method 23 is rather an accurate one on topology than grid level.…”

The increased growth of building complexity confronts the limited device resources, especially for lightweight personal digital devices. The research of handling these complex buildings with limited resources has become a pivotal research topic. This paper explores the task of lightweight indoor path planning in complex building information modeling (BIM) buildings. Both the environment modeling and path searching are important addressed through indoor path planning with a lightweight web-based approach. A lightweight framework is designed in which the complex indoor path planning of a whole BIM building can be simplified into many local path searching of the building's interior spaces and all the online computation is decreased within no more than two simpler ones. In addition, an automatically indoor environment modeling method is proposed to partition the BIM building into many local interior spaces, constructing their spatial relationship and local grid map in a multilayered network. In the end, a heuristics optimized A star algorithm is implemented to speed up the shortest local path searching for the case of the path ends in a narrow corner. The final experiment shows that the online computational cost can be reduced greatly and dynamically to an average of 2 s when searching for the shortest path in a complex BIM building.

“…For instance, the managers have to check both the components and the attribute values of the building (e.g., the width of the court) in conformity checking (Zhang and El-Gohary, 2015a). In the process of indoor navigation, it is necessary to extract geometric data from BIM for the construction of path navigation algorithm (Zhou et al, 2020). In the operation and maintenance phase, equipment managers need to extract information in various aspects of the operation performance from the BIM model , while maintenance staff tends to extract failure pattern information in building systems and components from CMMS databases (Gunay et al,2019).…”

Building Information Modelling (BIM) captures numerous information the life cycle of buildings. Information retrieval is one of fundamental tasks for BIM decision support systems. Currently, most of the BIM retrieval systems focused on querying existing BIM models from a BIM database, seldom studies explore the multi-scale information retrieval from a BIM model. This study proposes a multi-scale information retrieval scheme for BIM jointly using the hierarchical structure of BIM and Natural Language Processing (NLP). Firstly, a BIM Hierarchy Tree (BIH-Tree) model is constructed to interpret the hierarchical structure relations among BIM data according to Industry Foundation Class (IFC) specification. Secondly, technologies of NLP and International Framework for Dictionaries (IFD) are employed to parse and unify the queries. Thirdly, a novel information retrieval scheme is developed to find the multi-scale information associated with the unified queries. Finally, the retrieval method proposed in this study is applied to an engineering case, and the practical results show that the proposed method is effective.
