Almost no construction project performs totally as planned as dynamic changes are frequently needed. These changes can be ascribed to the high uncertainty, which is evaluated as potential causes of risks and risks is in turn are evaluated as potential causes of plan changes. Several concepts from the Business Process Modeling domain are adopted to build an(More)
Engineering is a discipline providing one of the most challenging environments for integration and interoperabil-ity. Great hopes are wired and wireless networking technology that is redefining the role of information technology in civil engineering. It used to provide software tools for the design and analysis and access to common design information.(More)
This article describes a collaboration methodology for virtual organizations where the processes can be automatically executed using a hybrid web service, grid or cloud resources. Typically, the process of deriving executable workflows from process models is cumbersome and can be automated only in part or specific to a particular distributed system. The(More)
Numerous risks impact construction projects and cause changes in their management plans. Unfortunately, not all of them can be identified in advance. Hence, risk management in construction requires proactive as well as reactive treatment. Among the other risk management tasks, risk treatment requires a sound methodology to rapidly develop concrete change(More)
Projects in the building industry are extremely dynamic and affected by several constraints. Therefore, common principles should be established throughout the construction industry that allows flexibly specifying and combining construction project information for the inter-organisational collaboration. New members should be supported to join and leave the(More)
In contrast to the predefined and static processes in most industries, the design and construction processes in the building industry are extremely dynamic. Technical conflicts and modified design goals will lead to ad-hoc changes within the workflow. They are no exception but usual. Therefore, common principles must be established throughout the(More)
—Multi-Models address issues of nD mod-eling problems in construction information processes. They provide a temporary and loose coupling by aggre-gating instances of possibly orthogonal domain models and expressing explicit relations between their elements. To provide a base for prototypical and specific multi-model support as well as the development of(More)
