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 Pilot Study: Towards BIM Integration - An Analysis of Design Information Exchange & Coordination
Abstract: Construction projects are costing too much and taking too long as a consequence of unnecessary omissions and errors in project documentation and sub-optimal co-ordination of design information between consultant disciplines. One reason for this is that much project production information relies substantially on human input and subsequent multiple manual checks and cross-referencing operations which, on projects laden with design data, inevitably leads to errors or missing information. If implemented intelligently BIM may offer a solution.Typically projects are becoming increasing complicated in nature, requiring more specialist discipline input resulting in a much greater volume of technical information which in turn requires to be co-ordinated and kept up-to-date and relevant through the life cycle of a project. In such contexts conventional project filing systems and information work-flows are becoming un-manageable and there appears to be a need for more clearly defined and agreed information deliveries which if adequately tested, could be standardised. The theory behind BIM provides an exciting integrated solution for project information management however in this new process further effort is required to define the content of information deliveries and a number of basic who?- what?- when?- how?- questions relating to object and property definitions need to be resolved.This study investigates and attempts to define the functional requirements for integrated information management through the design stages of a construction project focusing on architectural practice requirements within the residential sector in Sweden. The pilot study aims to prepare for the development of an extensive study of information deliveries and standardisation needs using BIM.The study utilises buildingSMART Alliance's new Building Information Modelling Execution Planning Guide together with a case residential construction project in Sweden. The principle BIM planning procedures are applied to the case, tuning requirements to the specific project and localised to support Swedish classification standards. Through the enquiries required to develop and define these processes, a new information exchange protocol emerges, tuned to the Swedish residential sector.
