Ontology-aided FMEA for construction products

Abstract: The goal of improving the quality and the maintenance of building products, and the will to integrate the sustainable development objectives led us to propose an original method based on the use and adaptation of the Failure Modes Effects and Criticality Analysis (FMEA). This method relies among others on ontology use. It facilitates the FMEA proceeding. This paper aims to introduce innovative software specifically developed to perform more easily FMEA on building components. This software takes advantages of a structured knowledge base and an inference rule engine that allow a complete and formal description of the product to be analysed and an exhaustive analysis of all failures (degradations) that may occur.

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."
