This article describes our conceivability of a software platform, which should facilitate collaboration, coordination and communication within virtual-networked cooperations in the context of civil and building engineering projects. These cooperations are characterized by highly dynamic structures and complex heterogeneities, frequently leading to problems and conflicts among the participants of these cooperations. In order to avoid these undesired consequences, we propose a component-based, distributed, and adaptable software platform, which should cope with the described problems of networked cooperations. We argue that such platform should support a decentral Peer-to-Peer architecture, that is, a network consisting of independent hosts (peers) without a single server. Furthermore, we introduce awareness and coordination concepts, regulating the collaboration of participants using the platform.
