Artificial intelligence for safety and health
Computer vision for site safety and housekeeping
This project applies computer vision to enhance construction site safety by detecting poor housekeeping, missing barricades, and hazardous conditions through automated image and video analysis. Using data from CCTV, drones, and body-worn cameras, the system performs image classification, object detection, and change detection to identify risks in real time.
Our tools include AI-enabled dashboards, Telegram alerts for site teams, and customisable reports to support timely interventions and improve overall site conditions. We also explored supervised learning approaches to identify cluttered environments and dynamically detect crane load fall zones.

Projects
Construction safety leading indicators
This project focuses on identifying and modelling leading indicators to proactively assess subcontractor safety risk and forecast safety performance outcomes. Leveraging safety analytics and machine learning techniques, the research extracts meaningful insights from historical data to support the early identification of high-risk contractor profiles and strengthen safety management practices.
These insights enable organisations to prioritise preventive interventions, track safety performance, and develop a data-informed safety culture that is proactive rather than reactive.

Projects
Text mining
This project applies machine learning and natural language processing (NLP) techniques to automatically classify construction accident descriptions. By leveraging text mining, organisations can extract actionable insights from unstructured safety reports and documentation, enhancing their ability to identify trends, root causes, and preventative measures. These insights support data-driven decision-making to reduce accidents and improve workplace health and safety.

Education and training
Digital simulation games
This project involves the design and development of 3D digital game-based learning (DGBL) tools to enhance construction safety training and education. These interactive simulation games immerse learners in realistic scenarios, helping them develop critical safety competencies in a risk-free environment.
SafeSim Risk (SSR) is a multiplayer game designed to train players in hazard identification and safe work practices on a virtual construction site. SafeSim Investigation (SSI) teaches players how to conduct incident investigations by collecting digital evidence and uncovering root causes through gameplay. SafeSim Design (SSD) is a DGBL platform created specifically for designers to learn about construction design risks and effective mitigation strategies. Its content is aligned with the IES-NUS DfS Library to reinforce upstream safety principles. These games aim to cultivate hazard awareness, investigation skills, and design-for-safety thinking through engaging, experiential learning.
ProjectSim is designed to enhance project management competencies through immersive, scenario-based learning. By navigating realistic project challenges, learners can apply key techniques such as earned value management (EVM) and earned duration management (EDM) to monitor performance, manage risks, and make data-driven decisions.

Projects
Immersive technology for learning
This project leverages virtual reality (VR), augmented reality (AR), and mixed reality (MR) technologies to enhance construction and engineering education. We developed a VR and MR-based learning tool for incident investigation, featured in RESCUE Act 3, providing immersive and interactive training experiences. In addition, we created a mobile app that uses AR and VR to teach structural systems to non-engineering students. These tools aim to improve learner engagement and understanding of complex concepts.

Enhancing professional development for adult learners
Our research focuses on advancing lifelong learning though innovative, technology-enhanced strategies tailored for adult learners. We have developed an adaptive learning system to support personalised upskilling for construction professionals. We are currently modelling self-regulated behaviours in video- and game-based learning environments. These projects aim to foster learner autonomy, optimise engagement, and improve performance outcomes in professional education.

Design for Safety (DfS) and safety management
DfS climate
Design for Safety (DfS) is an upstream approach that brings project stakeholders together early in the design process to identify and mitigate foreseeable risks across the project lifecycle. This project focuses on developing and measuring DfS climate where the shared perceptions among DfS review team members regarding the effectiveness of DfS policies and procedures.

Safety climate and culture
This project explores how truck drivers and migrant construction workers perceive safety policies, leadership, and practices in their work environments. Through surveys, interviews, and data-driven methods including interpretable clustering, we examine the factors shaping safety attitudes, identify challenges to building a strong safety culture, and propose targeted strategies for improvement. A key focus is understanding how national culture influences safety culture, especially in Singapore’s diverse migrant workforce. By analysing cultural dimensions and their impact on safety behaviours, we aim to develop tailored behavioural interventions that improve safety outcomes and better protect vulnerable worker groups.
