Semantic Building Information Model and Multimedia for Facility Management

Abstract

Abstract. In the field of civil engineering, the proliferation of stakeholders and the heterogeneity of modeling tools detract from the quality of the design process, construction and building maintenance. In this paper, we present a Web-based platform lets geographically dispersed project participants-from facility managers and architects to electricians to plumbers-directly use and exchange project documents in a centralized virtual environment using a simple Web browser. A 3D visualization lets participants move around in the building being designed and obtain information about the objects that compose it. This approach is based both on a semantic architecture called CDMF and IFC 2x3. Our framework, based on Building Information Modeling features, facilitates data maintenance (data migration, model evolution) during the building lifecycle and reduces the volume of data.

Building Information Modeling (BIM) for existing buildings — Literature review and future needs

“…BIM represents real buildings virtually over the whole LC as semantically enriched, consistent, digital building models [7,30,31]. BIM is realized with object-oriented software and consists of parametric objects representing building components [12,27,32]. Objects may have geometric or non-geometric attributes with functional, semantic or topologic information [7,29].…”

“…Existing reviews either cover one or two aspects separately or concentrate on few cross-sectional challenges. Functional issues in the areas of maintenance [7,11,12,14,20,45,[49][50][51][52][53][54][55][56] and deconstruction [2,24] are addressed separately and mainly for new buildings (see Table 3). Also, informational [26,27,50,[57][58][59][60], technical [19,31,40,43,45,[61][62][63][64][65][66] and organizational/legal [21,67] issues of BIM use are often examined separately.…”

“…As described functionalities require accurate information on objects, relations and attributes in BIM, maintenance and updating of information in BIM remains a major challenge and area of research [11,21]. Due to long lifetimes of buildings and infrastructure, recent research also adresses BIM model evolutions, continuous model maintenance and management of temporal data [12] as well as the interoperability with developing BIM and expert software [11,37] (see also section 4.2).…”

“…Due to long lifetimes of buildings and infrastructure, challenges arise from interoperability within the rapidly developing BIM models, expert functionalities and continuous model maintenance during building lifetime [11,12,37]. Besides, due to increased demand for semantic web technologies [12,67,179], mobile BIM and cloud computing [34,120,231,232] that further enhance applicability of BIM, challenges are to be met in management of temporal data, transaction management and synchronization in BIM [11,12,37,150]. [64,130] or post-processing of concealed, distorted, structural or semantic building information [19].…”

Comparison between traditional and digital preliminary cost-estimating approaches

“…As known, a building information model is realized with an object-oriented software (BIM Authoring tools) and consists of parametric objects representing building components [12][13][14]. These objects are characterized by geometric and non-geometric attributes [15,16].…”
