Utility-driven for boosting high-strength rebar operation productivity

Abstract

Abstract Aligning with industry trends towards digitalisation, sustainability, and the use of high-strength materials, this study aims to enhance the operational efficiency and environmental performance of high-strength rebar (HSS) construction. This study aims to address critical challenges in the construction industry, such as the need for digital integration, sustainable practices, and efficient use of high-strength materials by developing a comprehensive, data-driven framework for digital transformation focussed on optimising HSS operations. The core objective of this framework is to optimise HSS management by providing real-time, actionable insights. The study employs a closed-loop, hybrid methodology that integrates remote sensing for data capture from construction sites, utility theory to model complex decision-making under uncertainty across quality, safety, and environmental factors, and a data-driven optimisation model. By applying this utility-driven approach in a case study, the research demonstrates significant improvements, including a 15% increase in schedule adherence, a 3% reduction in material waste (MW), and measurable gains in operational efficiency, safety, and resource optimisation. Ultimately, this research provides a practical, utility-driven approach that offers clear metrics for progress tracking and resource optimisation, representing a significant advancement in lean and digital construction management.
