Making a smudge on collective (un)conscious: designing collaborative platforms for construction
Abstract: Collaboration and collaborative environments have been playing an increasingly important role in theconstruction domain. Designing and process modeling, knowledge management and dissemination,communities of practice – this is just an initial list of the building-related activities that benefit fromcollaboration- and services approaches characterizing the construction industry. In this paper, we discuss the phenomenon of collaboration in construction, study the existingcollaborative platforms that are used (or might be applicable) for different building-related activitiesand identify the main challenges that are currently not addressed in the current researches. Wefurthermore underline the role of services-oriented technologies for modeling industry- and businessrelatedprocesses,andshowhowtheyhavebeendefactoimplementedfortheconstructionindustry.Despitea largenumberofdifferentfit-for-purposecollaborativeplatformsforconstruction,weneverthelessunderlinethenecessityofa semanticallyrichcollaborativeenvironmentforheterogeneousconstructionexpertsthatwouldallowthemtokeeptheirownterminologyandworkingpractices,buttoacquireasharedunderstandingofacommontaskwithoutlosingitsintegrity.Inordertodoso,weintroduceourservices-basedapproachforactionalizingthe expert knowledgeand developing an information kernel of a discussed task. This approach forms a theoreticalfoundation for developing a collaborative platform, the Cross-Pollination Space, the semantics ofwhich is dynamically modeled by ontologies and the related interactions are enabled by services. Weshow how this framework allows enriching the collaborative environment during its functioning andsupports expert collaboration without imposing an artificial platform-specific terminology and/orcollaboration patterns.Finally, we canvas the ongoing and future works related to this research and discuss the particularitiesof their contextualization for the construction industry.

A design tool with integrated knowledgeand code checking for concrete beams
Abstract: Knowledge-based expert system technology has been applied most successfully todiagnosis problems. Expert systems have also been developed for fault detection,prediction, interpretation, monitoring and planning. Despite their useful applicability in theearly design stage of the structural design process there is a poor number of expert systemsdeveloped for the structural engineer. An expert system developed for structural design problems exhibits certain similarities todiagnostic expert systems. The results from the calculations have to be analysed anddepending on the diagnosis certain actions can be taken or advises can be given. Forsolving a design problem the expert system will first of all have the task of finding aninitial design configuration using heuristic knowledge based on rules of thumb and defaultvalues. Numeric algorithmic procedures are then applied to determine the performance ofthe design. The design process can therefore be thought of as being subdivided into adesign part and a diagnostic/analytic part. The problem of structural design can in generalbe characterised as a search for a solution amongst a large number of alternatives that allsatisfy the specified constraints.
