As-Built Modelling in Civil Construction

Abstract

The purpose of this research was to explore the immediate applicability of the as-built models produced for Crown Bridges Light Rail civil construction project. This study combined practical applicability assessments with exploratory activities that employed modern technologies such as the Internet of Things and Artificial Intelligence. The as-built dataset used in this study was prepared in both LandXML and IFC formats, covering the primary open BIM formats used in civil construction in Finland. Major part of this research was dedicated to examining as-built models in terms of their readability across various platforms, including modelling, viewing, and construction site management applications. Additional research components included models’ suitability for structure gauge analysis, their integration with sensor frameworks, their potential applications in machine learning workflows, and their compliance with relevant regulatory provisions. The analytical methods applied in this research included qualitative, comparative and exploratory approaches. The results demonstrated strong performance of the evaluated as-built deliverables across all of the above listed disciplines, while also identifying features requiring additional development and standardisation. This study provides applicable information on the value of as-built models for design, construction and maintenance professionals, as well as lays ground for future research and development.
