Identifying stakeholders’roles and relevant project documents for 4D-based collaborative decision making

To fully understand and effectively implement 4D building information modelling(BIM)models and methods,we need to develop a precise knowledge of which project digital documents should be used and how they influence the decision-making(DM)process.This article studies the convergence between uses of 4D BIM and digital project documents.We hypothesize that a clear visualization of the construction simulation through a 4D model is a useful source of information and a support for DM at collaborative meetings.Through this research,we continue to progress toward a new 4D-based collective decision device,so these elements will contribute to propose 4D BIM as DM support on architecture engineering construction(AEC)projects.Further,the present research will be complemented by results from questionnaires given at a later research stage.The article presents a brief review of BIM context to consider ways of fostering the implementation of all 4D BIM uses(not only visualization).It then introduces a proposition for 4D BIM uses implementation by the project development phase.It concludes by summarizing stakeholders’roles and documents relevant to 4D BIM uses.

Generic and SME-specific factors that influence the BIM adoption process: an overview that highlights gaps in the literature

Building information modeling/management(BIM)is an emerging technological and procedural shift in the architecture,engineering,construction and operation industry.In this study,we use an extensive state-of-the-art method to clarify the BIM adoption process and the factors that can influence the success or failure of BIM adoption,particularly during the implementation stage,which are not frequently found in the literature.As an innovation,the lexical field allocated to the spread of innovations is assigned to BIM(diffusion,adoption,and implementation).After recalling the definition of relevant terms and then removing the resulting inconsistencies in vocabularies,we investigate various studies to identify factors that influence BIM adoption and then unify all these studies in one coherent and consistent BIM adoption process model.We focus on factors that play a role in the adoption of BIM in small-and medium-sized enterprises(SMEs)because SMEs constitute the majority of companies in the construction sector.This research highlights and intends to fill in some gaps found in the current BIM adoption literature.

Semantics for linking data from 4D BIM to digital collaborative support

Synchronous collaboration sessions within the context of 4D BIM position construction professionals into a complex socio—technical system.This system includes hardware,software,people,and broader community aspects.This article strictly focuses on the ontology representation of synchronous collaboration sessions with collocated collective decision-making.The model is designed by considering various 4D BIM model uses while a digital multiuser touch table facilitates the collaboration between actors.The outlined ontological model aims to improve interoperability and to move toward a knowledge-driven,smart-built environment paradigm.A knowledge engineering methodology is outlined,by virtue of which the semantics of the presented model are defined and discussed.Concepts from nearby knowledge fields,especially from the Industry Foundation Classes,are reused.Several examples on querying the knowledge base according to the project meeting requirements are outlined to demonstrate the benefits of using the model.Although 4D BIM model data can be imported by using standard formats,capturing data about the social context remains a challenge in the future.This is expected to change the ontology model structure by considering user ergonomics,data modeling requirements,as well as technical implementation constraints.
