Effective digital collaboration in the construction industry – A case study of BIM deployment in a hospital construction project
2015
We examine a case of successful integrated BIM-based design in a construction project.We present a set of key factors influential to enable digital collaboration in this project.Key factors identified include: change agents, new roles, cloud computing, contracts, etc.We found integrated design to depend upon changing traditional work practices.The case is an example of BIM implementation and collaborative work in the AEC industry. Building information modeling (BIM) and related digital innovations can serve as a catalyst for more transparency, tighter integration, and increased productivity in the architecture, engineering, and construction industry. Yet, many project teams struggle with ho…
How is Building Information Modeling Influenced by Project Complexity?
2014
Virtual design and construction of buildings and architectural spaces require extensive collaboration among a diverse set of design professionals. The authors analyze e-collaboration performance in two construction projects of differing complexity, to gain an understanding of how collaborative design based on building information modeling (BIM) is influenced by the complexity of the building project. The findings suggest that the perceived business value of BIM depends on project complexity and that BIM-based collaboration does not yield unconditional positive implications for all types of construction projects. The authors argue that current practice would benefit from a more structured ap…
SIGA3D: Semantic Combination of IFC and GIS to support Urban Facilities Management
2011
The interoperability of Information Systems has been a research topic for over thirty years. While some forms of heterogeneity have been settled by the adoption of standards, some domains, such as the Urban Information Modeling (UIM), require specific research. The UIM combines information from the domain of Building Information Modeling (BIM) with Geographic Information System (GIS) within a collaborative platform. Using this platform, a set of heterogeneous actors takes part in the lifecycle of the urban environment through a 3D digital model. This ambition is faced with several gaps such as resolution of semantic heterogeneity in the lifecycle management system, the resolution of structu…
A Review of Building Information Modelling for Construction in Developing Countries
2016
Building Information Modelling (BIM) is wide ly seen as a catalyst for innovation and productivity in the construction industry. BIM can assist a more sustainable construction process that in turn may contribute to eradicating poverty in developing c ountries (Un ited Nation Millennium Goals). While BIM is increasingly be ing adopted in developed coun tries, implementations in the developing country context are rare. Research has establishe d how construction firms struggle from several limitations having to do with the socio - economic and technological environment found in developing countries. Examples of issues preventing BIM adoption include a shortage of IT - literate personnel as wel…
Identifying First Responders Information Needs
2016
At the onset of an indoor fire emergency, the availability of the information becomes critical due to the chaotic situation at the emergency site. Moreover, if information is lacking, not shared, or responders are too overloaded to acknowledge it, lives can be lost and property can be harmed. Therefore, the goal of this paper is to identify information items that are needed for first responders during search and rescue operations. The authors use an educational building fire emergency as a case and show how first responders can be supported by getting access to information that are stored in different information systems. The research methodology used was a combination of literature review,…
Serious games as a virtual training ground for relocation to a new healthcare facility
2016
Purpose This paper aims to enquire into how building information modelling (BIM) and gaming can be integrated to support professionals in their learning about the spatial layout of a new building. This knowledge is important to prepare building operation and facilities management (FM). Design/methodology/approach Ingrained in task–technology fit theory, this paper reports from a case study of a serious game staged in the graphical environment of a building information model. A series of interviews with the client, subject-matter experts and software developers involved in developing the game were conducted. The industrial setting for the study is a major hospital construction project in No…
Leveraging BIM and Big Data to deliver well maintained highways
2017
The Highway infrastructure is one of the most valuable assets for any state or national Government. Efficient operations of Highways lead to success of national and local economies as well as improve the quality of life of the general public dependent on it. In order to ensure aging road networks continues to move with its ever increasing number of users, requires maintenance and improvements to the road network at the highest standard. Increasing scrutiny over the cost of maintenance along with increasing pressure from Government and the public for transparency over road network spending, has made a strong case for more efficient management of the Highway road asset and traffic management…
An automatic tool for reconstructing monthly time-series of hydro-climatic variables at ungauged basins
2017
Abstract Integrative information models for filling/reconstructing hydro-climatic time-series are required for a variety of practical applications. A GIS-based model for a rapid and reliable assessment of monthly time-series of several key hydro-climatic variables at the basin scale, is here developed as plug-in and applied to the entire region of Sicily (Italy). The plug-in, once the desired basin outlet section and time-window are selected, uses appropriate spatial techniques and algorithms to identify its drainage area and estimate the corresponding mean areal rainfall and temperatures time-series. A recent regional regressive rainfall-runoff model is successively applied for the assessm…
Knowledge Base Approach for 3D Objects Detection in Point Clouds Using 3D Processing and Specialists Knowledge
2012
This paper presents a knowledge-based detection of objects approach using the OWL ontology language, the Semantic Web Rule Language, and 3D processing built-ins aiming at combining geometrical analysis of 3D point clouds and specialist's knowledge. Here, we share our experience regarding the creation of 3D semantic facility model out of unorganized 3D point clouds. Thus, a knowledge-based detection approach of objects using the OWL ontology language is presented. This knowledge is used to define SWRL detection rules. In addition, the combination of 3D processing built-ins and topological Built-Ins in SWRL rules allows a more flexible and intelligent detection, and the annotation of objects …
General and flexible methodology and architecture for CAPP: GF-CAPP system
2003
Although all researchers insist on the need to develop computer-aided process planning (CAPP) systems, they agree that one of its most significant shortfalls is the low level of generality and flexibility present in current proposals. One of the outcomes of this low level of generality--apart from its limited application domain--is the low level of integration achieved with CAD, CAM and PP&C systems. To ensure optimized running of the production system, it is also important to stress the need to develop alternative process planning that enables it to adapt to disruptions in production. Several factors play an important role in implementing these features, among which the following may be hi…
