Augmented reality as a performance-enabling tool for high-performance materials in the built environment: evidence from a lebanese building case study

Introduction High-performance materials (HPMs), including advanced insulation systems, high-strength concretes, engineered composites, and prefabricated façade components, are increasingly utilized in the built environment to enhance structural efficiency, durability, sustainability, and lifecycle performance. However, their successful implementation requires high levels of construction accuracy, coordination, and quality control to achieve the intended performance. Augmented Reality (AR) has emerged as a promising digital tool to bridge the gap between design intent and on-site execution, yet empirical evidence quantifying its effectiveness—particularly in developing and Middle Eastern construction contexts—remains limited. Methods This study evaluates the impact of AR-assisted construction workflows on the implementation quality of HPM systems through a case study of a mid-rise residential building project in Lebanon. The analysis focuses on the installation and coordination phases of advanced building envelope and structural components. Conventional construction workflows were compared with AR-assisted processes using an AR-based visualization and alignment system that overlays digital building models onto the physical environment. Data were collected through site observations, project records, and installation performance tracking. Key performance indicators (KPIs)—including installation accuracy, material waste, rework frequency, productivity, cost efficiency, safety, and stakeholder coordination—were quantitatively assessed. Comparative field data analysis and Spearman’s rank correlation were employed to evaluate performance relationships. Results The findings demonstrate that AR-assisted workflows significantly improve installation precision, reduce material waste and rework, and enhance overall cost efficiency and safety performance. Strong correlations were identified between installation accuracy, waste reduction, and cost performance, indicating that improvements in execution quality directly influence project outcomes. Discussion The results highlight AR’s role as a performance-enabling technology that extends beyond visualization by actively supporting the effective deployment of HPMs. By safeguarding the intended functional benefits of advanced materials under resource-constrained conditions, AR contributes to improved construction efficiency and sustainability. This study provides empirical evidence supporting the integration of digital construction technologies with material performance optimization and underscores AR’s strategic value in advancing sustainable construction practices in emerging economies.
