Transforming from linear society to circular society is fundamental to solve the climat chrisis. To make construction sector circulare, we first need to develop circular data models for built asset. Circular asset data will need to be updated through the life cycle to become a digital twin. Replacement of physical components serves as “triggers” for updating digital twins. But who are the actors in the updating process, and how do they cooperate? The paper present two Norwegian cases of “level 3 digital twin” (Elyasi et al, 2023), and the roles and actors that contribute to update the twinned data. Research …

Most studies that investigated the automated classification of construction incident reports relied on traditional machine learning approaches, line support vector machines, decision trees, and logistic regression. Those approaches, however, have limited capacity to capture rich contextual text information to inform predictions. This study, therefore, investigates the effectiveness of two transformer-based models, BERT and RoBERTa, in classifying construction site incident reports. The purpose of this research is to evaluate the performance of these models in capturing contextual and semantic nuances in incident reports and to determine which model is better suited for supporting safety management tasks in the construction industry.

CIB Conferences
Building facade inspections are crucial for ensuring structural integrity and occupant safety, traditionally requiring physical access that can be costly and risky. Recent advancements have seen the integration of Unmanned Aerial Systems (UASs) equipped with imaging technologies to facilitate these inspections. However, the primary challenge remains in the effective detection and precise localization of facade anomalies, such as cracks, stains, and specifically, thermal anomalies. This paper investigates the fusing of diverse data sources, specifically thermal infrared (IR) imaging and high-resolution RGB data, to enhance 3D registration of thermal anomalies. Utilizing a Computational Neural Radiance Field (NeRF) approach, it aims to …

Adaptive Segmentation Of Thermal Anomalies In Buildings Using Human-In-The-Loop Active Learning Capsule Networks, Yining Wen, Kaiwen Chen
CIB Conferences
Buildings account for 40% of energy consumption in the U.S., with significant energy losses stemming from poor insulation and leaks. To meet decarbonization goals by 2050, efficient methods for diagnosing and retrofitting thermal anomalies are essential. Infrared thermography (IRT), combined with emerging technologies like computer vision and deep learning, offers the potential for automating thermal anomaly detection and segmentation. However, challenges such as building diversity, scenario variations, and labor-intensive image annotation hinder model reliability and robustness. This study proposes a human-in-the-loop active learning approach to fine-tune the pretrained Capsule-based network (CapsLab) to enhance adaptability to new building scenarios efficiently. Using …

Sam-Based Segmentation Of Multi-Class Bridge Components From Diverse Real-Scene Inspection Images, Shengyi Wang, Yuxiang Huang, Nora El-Gohary
CIB Conferences
Traditional bridge inspection methods rely on manual visual inspection, which is time-consuming, labor-intensive, and potentially dangerous. Automated inspection approaches, which use unmanned aerial vehicles (UAVs) and computer vision, aim to address this issue. However, three knowledge gaps remain. First, although considerable research has been conducted on defect detection and segmentation in bridge inspection, there has been limited focus on segmenting and characterizing specific bridge components that contain defects. Such segmentation provides essential contextual information for understanding the importance of defects for maintenance decision making. Second, existing bridge component recognition approaches face challenges in generalizing across various scenarios, especially in close-range …

The speed of global biodiversity loss has highlighted the urgency of directing more capital into nature-positive investments. Subsequently, green real estate finance has an important role to play in filling this finance gap. Against this backdrop, the paper employs a case study methodology to critically review the harmonies and disparities between two alternative approaches to incorporate biodiversity in the building sector: the EU Taxonomy, representing a regulatory “top-down” push for minimum standards, and the “Biodiversity Building” concept which portrays an industry-driven “bottom-up” approach aimed at ecological regenerativity. The analysis reveals some fundamental differences between the scope, content, and applicability of …

Being ‘smart’ remains a prominent goal that many cities wish to achieve, not only for the excitement the awarding of ‘smart city status’ can generate, but also because smart cities are seen as the way to overcome current and future urban challenges. The International Organisation for Standardisation (ISO) is globally recognised for their standards, and in 2019 they released their Smart City Indicators standard (ISO 37122) which has since become a leading standardised methodology adopted by city leaders to guide their city smartness efforts. The ISO 37122 also links its smart city indicators to the United Nations (UN) Sustainable Development …

A Transformer-Based Semi-Supervised Learning For Occupant Feedback Evaluation, Min Jae Lee, Ruichuan Zhang
CIB Conferences
Indoor Environmental Quality (IEQ) focuses on ensuring that occupants experience comfortable and healthy indoor settings, covering factors such as temperature, humidity, air quality, acoustics, and lighting. Assessing IEQ from occupants’ perspectives is challenging due to the subjective natures of comfort and health perceptions. Existing methods for collecting direct occupant feedback, including surveys, questionnaires, observations, and interviews, frequently result in insufficient data, limiting the comprehensive and holistic understanding of occupant satisfaction in indoor environments. In response to these challenges, this paper proposes a semi-supervised learning-based framework aimed at deriving a metric of comfort and health satisfaction from sparse occupant feedback. Semi-supervised …
