Abstract
Buildings are spatial components that exist in a spatial context. Creating the geographical context for designers facilitates design analysis and municipal code compliance checks. Integrating BIM and GIS is beneficial for a wide range of spatial analysis and design validation. There are three main BIM and GIS integration approaches, which are BIM to GIS, GIS - BIM, and both GIS and BIM integrated in a separate tool or platform. This research focused on the second approach, which is GIS - BIM. Since both BIM and GIS are created for different domains and differ in their representation of data, the IFC schema was considered as the file exchange format for such integration. This is not new; however, most integration attempts using this approach have focused primarily on geometry with less consideration for semantics. A case study of a site divided into three zones with distinct geotechnical attributes was used for this research. After the transformation to IFC, the resultant model was linked into a Revit project to test its responsiveness when queried for design validation. This research demonstrates the flexibility of IFC for BIM and GIS integration. Additionally, semantics of the transformed GIS IFC data were established during the transformation. The topographical object, its property sets, and the hierarchical relationships were all modelled in the Feature Manipulation Engine (FME). However, the resultant GIS IFC model is not fit for use cases such as spatial boundary analysis or querying data within certain spatial constraints in native BIM environments. This research examines the possibility GIS - BIM models for analysis in native BIM environments.

Title:Napredek infrastrukturnega BIM-a z integriranimi prostorskimi podatki in izboljšanim pridobivanjem podatkov : magistrsko delo
Abstract:
Stavbe so prostorske komponente, ki obstajajo v kontekstu prostora. Ustvarjanje geografskega konteksta za oblikovalce olajša analizo načrtov in preverjanje skladnosti s predpisi urejanja prostora. Integracija BIM in GIS je koristna za širok spekter prostorskih analiz in validacije načrtov. Obstajajo trije glavni pristopi integracije BIM in GIS, in sicer BIM v GIS, GIS v BIM in tako GIS kot BIM, integrirani v ločeno orodje ali platformo. Ta raziskava se je osredotočila na drugi pristop, ki je GIS v BIM. Ker sta tako BIM kot GIS ustvarjena za različni domeni in se razlikujeta po predstavitvi podatkov, je bila shema IFC obravnavana kot format izmenjave datotek za takšno integracijo. To ni novost; vendar se je večina poskusov integracije s tem pristopom osredotočala predvsem na geometrijo z manjšim upoštevanjem semantike. Za to raziskavo je bila uporabljena študija primera lokacije, razdeljene na tri cone z različnimi geotehničnimi lastnostmi. Po pretvorbi v IFC je bil nastali model povezan s projektom Revit, da bi preizkusili njegovo odzivnost pri povpraševanju po validaciji načrta. Ta raziskava dokazuje prilagodljivost IFC za integracijo BIM in GIS. Poleg tega je bila med transformacijo določena semantika transformiranih podatkov GIS IFC. Topografski objekt, njegovi nabori lastnosti in hierarhični odnosi so bili modelirani v mehanizmu za manipulacijo feature (FME). . Vendar pa nastali model GIS IFC ni primeren za primere uporabe, kot sta analiza prostorskih meja ali poizvedovanje po podatkih znotraj določenih prostorskih omejitev v izvornih okoljih BIM. Ta raziskava preučuje možnost integracije modelov GIS v BIM za analizo v izvornih okoljih BIM.
