Bridge engineering involves many discrete stages throughout the life cycle of a bridge, within both the delivery phase of the infrastructure project and the subsequent operation and maintenance of the asset. Each stage comprises multiple complex processes by large project teams and relies on the efficient exchange of information throughout. Bridge information modelling is a form of 3-dimensiona...

Nature inspired engineering is state of the art paradigm, which exploits principles of natural systems to design man-made systems. The Open Source Software Engineering (OSSE) is a growing field that offers challenges and potentials. This paper proposes a model for OSSE that maps some features of atomic model to software engineering process. The model seeks bridge between academia and industry f...

In Software Engineering many text-based languages and supporting tools are used, forming the grammarware technical space. Currently model driven engineering is the new emerging paradigm for software engineering, which uses modelling languages and tools, forming the modelware technical space. Transition to the new technical space and interoperability between these two technical spaces is needed ...

Performance evaluation of a bridge is critical for determining the optimal maintenance strategy. An unsupervised bridge superstructure state assessment method is proposed in this paper based on fuzzy clustering and bridge field measured data. Firstly, the evaluation index system of bridge is constructed. Secondly, a certain number of bridge health monitoring data are selected as clustering samp...

Throughout the last century and in recent years, several bridge failures have taken place worldwide. Recent studies uncovered that primary cause of these collapses was human errors design, construction, operation phases. Regardless this finding, there is still a considerable gap between information known risk they represent for structural safety. Aiming better understanding errors, an identific...

The project of building a bridge is a canonical example of what John Law (1987) has termed ‘heterogeneous engineering’, involving the arrangement of human and nonhuman elements into a stable artifact. This paper reports ethnographic research on the work of civil engineers engaged in designing a bridge scheduled for completion by the year 2004. My emphasis is on a view of bridge-building as pers...
