MODELLING MULTI-CRITERIA DECISION ANALYSIS FOR BENCHMARKING MANAGEMENT PRACTICES IN PROJECT MANAGEMENT

Abstract: The link between management practices and worker’s motivations impacting construction productivity is being considered as significant among the research community. This research aimed to identify and analyse the underlying attributes impacting construction productivity from the site management perspective. This research presents a framework designed to analyse and quantify the relative relevance of different drivers in the determination of productivity levels and the degree of effectiveness of potential opportunities for improving performance of overall projects. Owing to the complexity of construction projects and underlying conflicting drivers influencing higher worker’s productivity, the Analytical Hierarchy Process (AHP) is employed to deal with interdependent relationships within a multi-criteria decision-making model. In the analytical approach, the large unstructured decision parameters are identified first and then are broken down into the manageable and measurable components using a top down hierarchical structure. This paper demonstrates an example to illustrate how to empirically analyse and prioritise a set of influencing parameters as selection criteria in devising appropriate management practices to ensure higher productivity vis-a_-vis optimum performance of projects.

Safety Training for Scaffolding and formwork Construction by Using Virtual Environment

Abstract: Scaffolding and formwork activities are the most frequent construction activities that exist in almost every construction project. Common site accidents such as falling from a height, formwork collapses frequently occur during these activities. Previous literature highlight that human-based factors are the major causes that lead to the scaffolding and formwork accidents. In this sense, safety training is crucial to prevent these accidents by improving the safety skills of trainees. Knowing that virtual technologies based trainings have a great potential to provide an effective training, we developed a virtual safety training tool called V-SAFE.v2 which simulates the scaffolding and formwork activities. V-SAFE.v2 supports both single and multi-user training scenarios. In the training stage, trainees interact with the autonomous agents to learn the essentials of the tool and the scaffolding and formwork construction skills. In the testing stage, trainees enter into the virtual environment to test their skills and safety knowledge that acquired during the training stage. Finally, trainees receive feedback based on their safety behavior at the end of testing stage. The preliminary results of this study demonstrate that V-SAFE.v2 is an effective safety training tool for the scaffolding and formwork activities.

Tools to Signal C2C Design Intention

Abstract: In this paper, we present a vision and requirements for how IT can support sustainable design and construction in the AEC Industry. We illustrate our vision with examples from a project designed by William McDonough Partners, a leader in the field of the design of sustainable building. As part of the design process, designers develop a multi-disciplinary design narrative that captures the essence of the design and the designers' intentions. However, today's IT does not support designers in developing and maintaining this narrative with the flexibility and integration required. We discuss the extent to which existing IT approaches address the requirements for design tools, and introduce the Perspective Approach as a way forward to address these requirements, applying the Perspective Approach to the examples. The Perspective Approach builds on project modeling approaches to enable engineers to establish the relationships of their information to the information produced by other engineers. In this way, an integrated project model is not prescribed by an a priori defined project modeling schema that has been implemented by software programmers, but emerges as the design evolves in response to project-specific challenges and opportunities. The Perspective Approach is our first attempt at developing a method to enable engineers to document, communicate, and explore the multi-disciplinary design narratives necessary for the design of sustainable buildings.

IFC based computer-integrated construction project management model

Abstract: In this paper, we present a conceptual framework enabling to manage broad set of activities supported by multi-module software application for construction project management. In order to maintain an integrated generic structure to enable interoperable use of standardized data in a general CPM model, we proposed an IT environment which is based on a formal process methodology, standardized product and process model (IFC), and overall architec-ture integrating technical (design) work, construction process planning and project management in an open and modu-lar manner. In this context, we developed Construction Management Phases for Software Interoperability, Organiza-tional and IT Management Processes with using of ARIS methodology in order to implement IFC views. Based on this, we outline a web-based environment enabling to plug in all component tools via a common client, providing a coherent GUI.

Integrating Building Product Models with Live Video Stream

Abstract: Various Building Information Models (BIMs) are increasingly used for data sharing and communication purposes in real estate and construction sector. This change can be seen as part of more general development where the main target is wide integration infrastructure to handle user interaction, business process, applications and data. Besides of new achievements in BIM technologies the described general development is enabled in an interesting manner by the overall technological integration that is bringing together traditional IT, telecommunication, Internet, TV and radio technologies and entertainment business. The resultant solutions have already changed clearly our working environment, its processes and business, and, more even radical changes are likely to appear. This paper shall present a research project addressing combination of building product models with live video stream applications. The research project named '4D Live' explores hardware, middleware and software platforms for the named purpose whilst the main target is to study emerging new sector specific business processes and changes arising from these solutions. 4D Live project is producing several demonstrative solutions where building models are combined with live video stream from one or several digital video cameras: i) Live internet based 4D, ii) Augmented reality web camera, and iii) Multi-Camera studio for BIM-Human interaction.

Keywords: BIM, building product models, augmented reality, visualizations
