“…There have been previous attempts to increase information sharing and reuse between stakeholders though a shared knowledge base [22] or by centralizing all data in a BIM model [37]. [30] demonstrates the semi-automated configuration of a building automation system by exporting BACnet objects from the BIM, enabling the exchange of information across the design, construction and operational stages of a building. Rather than adapting an existing representation to other stages of the building lifecycle, our approach translates these existing representations into a unified model.…”

Many different digital representations of a building are produced over the course of its lifecycle. These representations contain the metadata required to support different stages of the building, from initial planning and design, to construction and commissioning, through operations, audits, retrofits and maintenance. However, because of differences in the semantics, structure and syntax of these representations, the metadata they contain is not interoperable. We present a novel method for leveraging these representations to create a unified, authoritative Brick metadata model for a building that can be continually maintained over the course of the building lifecycle. A simple synchronization protocol relays inferred Brick metadata from existing metadata sources such as gbXML, Build-ingSync, Project Haystack and Modelica to a central integration server, which merges the metadata into a valid Brick model.

“…Building information modeling (BIM) relates to the data exchanged for the design, construction and commissioning of a building. BIM models contain extensive lists of building assets in addition to 3D geometry, and there is active research into extending the use of BIM for operation and maintenance (Yang and Zhang, 2006;Tang et al, 2020). However, BIM models lack direct representation of the contextual metadata described by Brick and Haystack (Bhattacharya et al, 2015a;Lange et al, 2018).…”

Current efforts establishing semantic metadata standards for the built environment span academia, industry and standards bodies. For these standards to be effective, they must be clearly defined and easily extensible, encourage consistency in their usage, and integrate cleanly with existing industrial standards, such as BACnet. There is a natural tension between informal tag-based systems that rely upon idiom and convention for meaning, and formal ontologies amenable to automated tooling. We present a qualitative analysis of Project Haystack, a popular tagging system for building metadata, and identify a family of inherent interpretability and consistency issues in the tagging model that stem from its lack of a formal definition. To address these issues, we present the design and implementation of the Brick+ ontology, a drop-in replacement for Brick with clear formal semantics that enables the inference of a valid Brick model from an informal Haystack model, and demonstrate this inference across five Haystack models.

“…Although these schemes are not yet fully developed, together with Information Delivery Manuals (IDMs), they support collaborative project management [30]. Research efforts show for example how Building Automation System (BAS) based systems which are used in facility management can be represented in an IFC structure [21]. While other researchers are still sceptical and consider that even with the further development of IFC, it does not seem feasible to switch from static BIM data to a dynamic web-based system [15].…”

The increased complexity of construction projects requires the involvement of a wide range of organizations throughout the project lifecycle-from conceptual planning to decommissioning. Construction project teams, therefore, differ from teams in other industries as they comprise individuals who are employed by organizations that conduct different businesses. These many separate organizations working together in a close harmony over the duration of the project is fundamental to the overall business of construction. Project success relies heavily on the management of the flow of information among players and access to the right information is vital to efficiently perform the work. Therefore, an efficient information access and effective information exchange methods internally and externally with other organizations needs to be achieved. The model-centric approach introduces a unique solution to solve the problems with the information jungle, inconsistency, and disintegration associated with the traditional document-centric approach. As such, a coherent use of information management is required to merge, comanage, and semantically connect the information and artifacts generated throughout the project phases. Adopting a model-centric approach creates a single point of truth that centralizes information and facilitates access to it. A transformation plan is needed to outline the shift of the construction from document-centric to model-centric. This paper proposes a strategy to support the model-centric transformation of the Architecture, Engineering, and Construction (AEC) industry. Five strategic objectives are outlined and discussed in this paper highlighting considerations that need to be made to enable this transformation. This study describes the "what" necessary to enable and support a model-centric AEC industry.
