20.500.12556/RUL-162787 Information management for BIM-based quantity take-off openBIM workflow and applications Upravljanje informacij za določitev količin na osnovi BIM odprti BIM delotok in uporabe Ta disertacija preučuje delotoke BIM (angl. Building Information Modelling) za določitev količin in oceno stroškov v zgodnji fazi načrtovanja, s poudarkom na uporabi odprtih standardov, še posebej IFC (angl. Industry Foundation Classes) in specifikacije IDS (angl. Information delivery specification). Študija se osredotoča na delotoke za opredelitev informacijskih zahtev, pripravo in validacijo modela. Uporabljena so bila naslednja orodja: UsBIM.IDSEditor za opredelitev alfanumeričnih informacijskih zahtev; Revit za pripravo modela in izvoz IFC; BlenderBIM za validacijo modela; ter Power BI, Navisworks, Bexel Manager in IfcOpenShell za izračun količin, določanje stroškov in simulacijo gradnje. V delu je prikazana integracija Power BI za QTO in oceno stroškov, ki omogoča boljše razumevanje stroškov projekta in pomaga pri odločanju. S Python knjižnico v okolju IfcOpenshell smo omogočili avtomatizacijo in prikaz učinkovitega iskanja lastnosti ter izračuna količin in ocene stroškov. V delotoku z Navisworks, ki vključuje izvoz podatkov QTO v Excel so potrebni dodatni koraki za filtriranje potrebnih informacij za oceno stroškov, zato je bil razvit skript v Pythonu, ki poenostavi ročno delo, čeprav je izdelave simulacija terminskega plana ostala ročna, kar je lahko zamudno in vodi do napak. V nasprotju s tem je bilo mogoče delotok z Bexel Managerjem bolje avtomatizirati za določitev količin in oceno stroškov. Skript C# shrani bistvene podatke o terminskem planu v izvoženi model IFC, kar zagotavlja skladnost s specifikacijami, ki jih je mogoče strojno brati. Ta raziskava nudi vpogled v delotoke, ki bi lahko znatno izboljšali, določitev količin, oceno stroškov in načrtovanje, kar bi lahko bilo koristno za raziskovalce in ljudi v praksi, ki delajo na tem področju. This thesis explores the application of Building Information Modeling (BIM) workflows for quantity take-off (QTO) and cost estimation in the early design phase, with a focus on leveraging open standards, specifically the Industry Foundation Classes (IFC) and Information Delivery Specification (IDS). The study concentrates on workflows for defining information requirements, model preparation, and validation. The following tools were utilized: UsBIM.IDSEditor for defining alphanumeric information requirements; Revit for model preparation and IFC Format exportation; BlenderBIM for model validation; and Power BI, Navisworks, Bexel Manager, and IfcOpenShell for quantity take-off, costing, and construction simulation. The research particularly focused on integrating Power BI for QTO and cost estimation, providing a clearer understanding of project outcomes and aiding decision-making. Additionally, Python programming with the IfcOpenshell library was used to automate and demonstrate efficient property querying and perform quantity take-off and cost estimation. The study also explored a Navisworks workflow involving QTO data export to Excel, requiring additional steps to filter relevant information for cost estimation. A Python script was developed to streamline this process, although construction schedule simulation remained largely manual, potentially introducing errors and inefficiencies. In contrast, the Bexel Manager workflow automated both QTO and cost estimation with minimal manual intervention. A C# script stored essential schedule data within the exported IFC model, ensuring compliance with machine-readable specifications.This research offers insights into potential workflows that could significantly enhance cost estimation and scheduling, proving valuable for researchers and practitioners involved in cost estimation. master thesis BIM OpenBIM IFC QTO model validation cost estimation construction schedule magistrska dela BIM gradbeni razpored ocenjevanje stroškov validacija modela odprti gradbeni informacijski model količinski izračun true false false [I.
