An IT oriented approach supporting the integration of technical risk, quality, environment and safety management in construction

Abstract: "I.T Context I.T. plays a key role to connect risk management with an integrated three dimension management system integrating quality, environment and safety management. Planning Techniques in construction aims to support the decision integration in the on/off site interfaces of construction processes. Starting just from the design phase the quality management strategies integrated with the performance theory allow to formulate a full list of requirements for project activities which can effectively stored in product models of construction elements. The technical risk analysis aims to operate a large performances analysis in on/off site processes. The risk analysis supports quality management in construction planning for determining a graduation of levels of performance required to the management system, which means identifying the specific project criticality in time, cost and quality fields and combining the most appropriate measures of prevention. Objective The objective for the developing research has been focussed on a planning technique integrating the information flow from the design phase to the construction process, oriented to allow the main contractor and the subcontractors to utilize quality plans schemas and risk analysis deriving from design phases as input in the risk analysis detailing and quality plans refinement. Methodology By a widespread collaborative analysis, dealt with an AI planning methodology applied in the construction domain, it might be possible to identify all actions aiming at reducing and preventing failure risk, intended as specific non conformance risk of elements and activities characteristics, and develop the right organizing strategies to increase the contractor's reactivity toward failure and defects. The Failure Mode and Effect Analysis (FMEA) methodology and the quality management applied to the construction planning are developed by means an intensive data exchange involving the project operators – e.g. designer, owner, contractor and subcontractor – in identifying the failure risk and in planning the prevention and control measures. Results An experimental FMEA system for analyzing risk factors in construction planning is advanced. Based on a schema of integrated tools, the techniques aims to provide a cooperative planning system toward a systematic approach representing a non conformance technical risk analysis in construction management."

IS tools for knowledge management in public construction projects

Abstract: This paper focuses on the possible tools of knowledge management by exploring offered, needed and wanted knowledge. We study knowledge management by exploring how the tools are utilized currently in case projects in Finland and how new tools could improve the processes. We also aim to study what kind of obstacles there are for IS tools utilization. New ways of organizing work are resisted and people very soon become cynical and unintended consequences of techno change failure hinder the success of the new change efforts. It is important to be aware of this and change efforts should be implemented in project work by letting the practitioners effect the change and select the way of working. We also found that often ICT have positive effects on the challenges but that often there is a critical mass problem, where the benefits are not yet gained if there are not sufficient users.

Kochonen Neural Model for Destructive Seismic Waves

Abstract: The paper is devoted on the problem of real-time earthquake prediction. An approach for realtime prognoses, based on classification algorithm of strong motion waves with neural network and fuzzy logic models is suggesting. As input information for the neural network, build with Kochonen learning rules, are given the parameters of recorded part of accelerogram, principle axis transformation and spectral characteristics of the wave. With the help of stochastic long-range dependence time series analysis is determined the beginning of destructive phase of strong motion acceleration. Developed seismic waves classification gives possibility to determine different kind prognoses models for different king of classified waves. The prognoses of destructive seismic waves are realized with learning vector quantization and self-organizing map.

Civil Infrastructure as a chaotic socio-tecnico systems support collaborative innovation

Abstract: The web is no longer just a media or communication outlet. It is morphing into a socioeconomic fact of life. The advancement of semantic web and the increased penetration of social are empowering people to harness their collective intelligence to create, collaborate and trade in knowledge. Starting from this observation, a scenario for community-based, knowledge-intensive environment for development and management of civil infrastructure is presented. The proposed scenario was inspired by similar trends in other industries and analysis of recent cases where the web influenced civil infrastructure development and planning. The proposed scenario embraces open, bottom-up decision making process where communities are empowered to develop, share and test ideas for infrastructure projects. Engineers and public officials are responsible for supporting the self-organizing emergence of these, expectedly, chaotic ideas. Putting the development process on the edge of chaos supports innovation and does not mean randomness. Consequently, it should be embraced by all. Accordingly, our analysis tools have to be geared more towards analysis of networks of people and their ideas; support autonomous evolutionary approaches that can collate chaotic ideas; providing communities with semantic-enabled analysis tools to support the generation of ideas; encourage the evolution of infrastructure Apps; and provide platforms for their dynamic linkage.

Keywords: infrastructure, collective intelligence, socio-technical system, networked knowledge, information system, social and semantic web.
