The rise of Construction 4.0—driven by digitalisation, automation, and data-intensive technologies—is radically reshaping the construction industry. While its technological innovations are widely acknowledged, their implications for industrial relations remain underexplored. In this study, we conduct a systematic literature review (SLR) of 91 peer-reviewed articles published between 2010 and 2024, aiming to synthesise emerging knowledge on how Construction 4.0 is transforming workforce dynamics, employment models, and labour relations. Using NVivo software and an inductive thematic approach, we identify seven key themes: workforce transformation, the attraction of new generations and women, skill requirements and workforce development, supply chain and logistics optimisation, digital twin technology in project management, the emergence of new business models, and safety and risk assessment. Our findings highlight both opportunities—such as improved collaboration, skill diversification, and enhanced productivity—and challenges, including job displacement, digital ethics, and widening disparities between developed and developing countries. Recent studies from 2023 and 2024 underscore routine-biased changes in workforce structure, evolving project management practices through digital twins, and critical skill shortages within the sector. Furthermore, contemporary policy shifts and increasing labour tensions in some regions reveal deeper socio-economic implications of digital construction. This review contributes to a more holistic understanding of how technological innovation intersects with social systems in the built environment. The insights presented offer valuable guidance for policymakers, educators, and industry leaders seeking to navigate the evolving landscape of Construction 4.0.

The design and construction of adaptive façades have garnered increasing attention as a means to enhance the energy performance and sustainability of high-rise residential buildings. Adaptive façades can dynamically respond to environmental conditions, reducing reliance on energy-intensive systems and improving occupant comfort. Despite their potential, research on adaptive façade systems in the context of high-rise residential buildings, particularly in Australia, remains limited. This study aims to bridge this gap by identifying the key design parameters, challenges, and optimisation methods for adaptive façades. Through a combination of a comprehensive literature review and 15 semi-structured interviews with industry experts, this research provides insights into the design and performance of adaptive façades. The key findings reveal that the successful implementation of adaptive façades depends on a range of factors, including material choices, shading system typologies, and advanced simulation tools for energy performance analysis. A significant outcome of the study is the development of a conceptual framework that incorporates these design elements with environmental factors and building energy simulation, offering a structured approach to optimise adaptive façade performance. The framework assists architects and engineers in creating energy-efficient, sustainable high-rise residential buildings tailored to the Australian context. Additionally, the study highlights critical challenges, such as financial barriers, regulatory gaps, and the need for improved maintenance strategies, which must be addressed to facilitate the broader adoption of adaptive façades in the residential sector.
