Abstract

Building Information Model Pre-Processing for Automated Geometric Quality Control Martín Bueno and Frédéric Bosché Pages 17-24 (2022 Proceedings of the 39th ISARC, Bogotá, Colombia, ISBN 978-952-69524-2-0, ISSN 2413-5844) Abstract: Geometric quality control (QC) in a construction project is an important but time-consuming and not value-adding task. While significant progress is being made in construc-tion digitalisation, geometric QC processes remain highly manual and inefficient. This manuscript proposes a new methodology to pre-process initial information contained in the as-designed Building Information Model ('BIM model' hereafter) and obtain a full list of the geometric QC tasks that need to be conducted over the duration of the corre-sponding construction project. The proposed methodology employ a network graph constructed automatically from the BIM model information; a dictionary of types of geometric QC (e.g. dimensions to be checked with tolerances) that ap-ply to the given project ; and a QC digital manager that ties both elements together and identifies the list of unique geo-metric QC tasks that need to be conducted throughout the given project. The workings of the proposed methodology are illustrated with a case study, for some QC specifications ex-tracted from the EN 13670 standard. These demonstrate its usefulness to exhaustively establish and record all geometric QC tasks required over a project.
