Distributed common data environment using blockchain and Interplanetary File System for secure BIM-based collaborative design

Confidentiality-minded framework for blockchain-based BIM design collaboration

Knowledge management is a newly emerging, interdisciplinary business model dealing with all aspects of knowledge within the context of the firm, including knowledge creation, codification, sharing, and how these activities promote learning and innovation. In practice, knowledge management encompasses both technological tools and organizational routines in overlapping parts. This paper presents discipline knowledge management from historical viewpoint, driving factors and importance of knowledge management. Final part of the paper presents basic facts about knowledge management systems and their role in the enterprise

Creating the Discipline of Knowledge Management

Information Sciences and Systems 2015

During the lifecycle of construction projects , documents and resources should be shared by partners in a collaborative and secure way. Starting from the Building Information Modelling (BIM) paradigm, we propose the Smart BIM Folder (SBF), a cloud-oriented framework enabling project teams to share construction documents on collaborative nodes, respecting security requirements of documents sharing. The core idea is to consider the SBF as a single, collectively-operated virtual resource accessed via a cloud-based catalogue. The paper proposes mechanisms for document sharing respecting both the typicality of BIM projects and security requirements of stakeholders in such sharing. We discuss cloud architecture issues related to the implementation of the SBF as a cloud service.

Enabling Secure and Collaborative Document Sharing in BIM Processes

Engineering projects may involve the efforts of specific partners experts in various disciplines. Grid and Web service technologies enable engineering project teams to perform resource discovery, selection, negotiation, and composition in a networked environment. However, the need arises for trust relationships, allowing team entities to participate in the project under security guarantees of privacy, of authorized disclosure of project data, and of correct users’ credential management. This paper proposes a Web service based framework to support this process. Giving prominence to the needs of a secure and dynamic collaboration in the style of a Virtual Organization (VO), the paper identifies and models the trust aspects featuring actors and objects involved in engineering team collaborations. An architecture is illustrated, centered around a Security Manager component supporting security in the composition and execution of distributed engineering services. A prototype implementation is presented.

Modeling Trust Relationships in Collaborative Engineering Projects

The growing complexity of the construction sector – due to the proliferation of products, techniques, and needs related to side, not secondary, aspects of objects (environmental impact, energy efficiency, durability, safety, etc.) – means that the current management styles in construction processes are no longer appropriate to their context. Therefore, the construction sector faces an inevitable process of growth in which knowledge is an indispensable resource. The purpose of this paper is to show how knowledge associated with construction processes can be represented using Knowledge Management techniques. The analysis of such knowledge uses a mixed top-down and bottom-up approach, which can formalize it and make it ready for easy access and search. The underlying goal is the rational organization of large amounts of data using the knowledge that characterizes the various stages of a construction process. Elementary Products could be the core concepts that can group the objects associated with such process, guiding the management of relevant information and knowledge involved in construction processes. The formalization was used to define a prototype implementation of the Knowledge Management System using DSpace.

Knowledge in Construction Processes

Over the last few years, the management and organizational aspects of the construction process have undergone a profound reflection that is closely linked to the development and the clear changes in the market. Such market is characterized by a rapid change, a strong growth in technology, and by a widespread and transparent information. International character, knowledge and innovation are key elements to win an increasingly exasperated competition. Moreover, the growing complexity of the construction sector - due both to the rapid proliferation of products and innovative technical solutions, and to the need to take into consideration side, but not secondary, aspects of the object (environmental impact, energy efficiency, durability, safety, etc.) - points out that present management patterns of the construction process are no longer appropriate to the context in which one operates. Therefore, the construction sector faces an inevitable process of growth in which knowledge is an indispensable resource. The present article aims at showing how Knowledge Management techniques (KM) might represent a possible tool to assist in achieving such goals through a rational organization of large amounts of data and through a corporate use of the knowledge that characterizes the various stages of a building process.
