The Internet is being increasingly used as a communication backbone of the construction industry. Through Web browsers and other standard tools, design and planning communication and information exchange take place. Several dotcom companies are offering such collaboration environments for rent. However, these environments are closed, project-centred and(More)
Interoperability within Virtual Organisations (VOs) is still only weakly supported by IT frameworks. Whilst service level interoperability has made remarkable progress since the emergence and the rapid growth of SOA and Grid technology in the last years, business processes – which are the driving force of each VO – still suffer distinct conceptual gaps(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)
This paper presents a process-based discrete-event simulation library for construction project planning. Business process models are used to build an accumulative knowledge base for standard construction processes in form of a ready to use process templates. The library aims to reduce the time and efforts needed to create simulation models for a(More)
