Quality assurance of BIM models in project management : master thesis

Building Information Modelling (BIM) has been modifying how building information is produced and communicated among the AEC stakeholders. For one side, BIM acts as a facilitator methodology; from the other side, it slows down the process by increasing the need of managing and controlling the information produced across project stages. It is acknowledged that the model quality and reliability depends directly on how the data is structured beforehand. Therefore, the study focused on defining a framework for quality assurance of BIM models addressing the need to assess, manage, and maintain the information quality inside the authoring tool. The framework englobes three main parts: (1) preparation, (2) structuring the modelling process, and (3) application. A fluid workflow was proposed by addressing the requirements and quality acceptance criteria from the start of the project and integrating QA/QC tools into the modelling process. Yet, the field of quality checking is taken from the organisational perspective to provide a methodology that supports the team in generating quality project information and maintaining the model's quality across different projects. The proposed framework has the potential to be applied in any authoring software. Among the contributions of the current work, the application of rules in the format of expression-based properties is highlighted. The study regarding its applicability for quality checks resulted in the generation of six categories of computable rules that feedback with COMPLIANT, NOT COMPLIANT or NOT APPLICABLE discrete values. This feature allowed the BIM objects to perform automated self-checking that can be easily integrated into the modelling stages. Furthermore, the rules feedbacks enables the generation of data for the quality assessment of the BIM model.

Abstract

Informacijsko modeliranje zgradb BIM (angl. Building Information Modelling) spreminja način, kako ustvarjamo projektne informacije in kako komunicirajo deležniki gradbenih projektov. BIM je po eni strani pospeševalna metodologija, po drugi strani pa zavira, saj povečuje potrebo po boljšem upravljanju projektnih informacij in nadzor kakovosti projektnih informacij, ki se ustvarijo skozi faze projekta. Na splošno velja, da je kakovost in zanesljivost modela neposredno odvisno od tega, kako so predhodno uporabljene informacije strukturirane. Zato se pričujoča študija osredotoča na razvoj ogrodja za zagotavljan je kakovosti modelov BIM in naslavlja potrebo po presoji, upravljanju in vzdrževanju kakovostnih projektnih informacij v avtorskem okolju. Ogrodje obsega tri glavne dele: (1) priprava; (2) strukturiranje procesa modeliranja in (3) aplikacijo pristopa. Predlagamo tekoč delotok, ki je skladen z zahtevani in kriteriju sprejemljive stopnje kakovosti od začetka projekta. Ogrodje je izdelano na način, da se zagotavljanje in nadzor kakovosti (QA/QC) integrira v proces informacijskega modeliranja. Pri tem je področje preverjanje kakovosti obdelano iz organizacijskega vidika, da bi lahko zagotovili metodologijo, ki bo opolnomočila projektnim ekipam, da bodo lahko generiral visoko kakovostne projektne informacije in vzdrževale kakovost modelov preko več projektov. Predstavljano ogrodje se lahko implementira v kateremkoli avtorskem okolju. Med bistvene prispevke pričujočega dela izpostavljamo uporaba pravil v formatu izrazno-definiranih pravil. Študija uporabnosti tovrstnega načina preverjanja kakovosti z izraznimi pravili je vodila do šestih identificiranih kategorij, ki so računsko preverljive in lahko kot funkcija vrnejo rezultat v obliki treh diskretnih zalog vrednosti: JE SKLADEN; NI SKLADEN ali NI RELEVATNO. Slednje omogoča, da se predmeti BIM samo-preverijo, kar se lahko na enostaven način vgradi v več faze modeliranja. Poleg tega, tovrstna preverjanje omogoča samodejno generacijo podatkov za presojo kakovosti modelov.
