As an academic working at the intersection of project management, digital construction, and sustainability, my research journey has consistently centred on a fundamental question:
How can we design and manage infrastructure systems that not only perform efficiently, but also create meaningful value for people and society?
Across my work in the UK, China, the Middle East, and Europe, I have observed that the most successful projects are not necessarily those with the most advanced technologies, but those that effectively integrate human, organisational, and technological dimensions – a reality evident in both industry and academia. My research has explored areas such as AI-enabled BIM, digital twins, and data-driven asset management, with a particular focus on enhancing predictive maintenance, lifecycle performance, and sustainability outcomes. Yet, a recurring insight has consistently emerged:
Technology alone does not transform the built environment – people do.
Therefore, this Special Issue on People in Construction is both timely and necessary. It reflects a growing recognition that achieving sustainable, inclusive, and high-performing infrastructure requires a deeper understanding of human behaviour, perception, leadership, and societal interaction. The construction and infrastructure sectors are undergoing profound transformation, driven by digital innovation and increasing societal expectations. However, despite rapid technological advancements, the sector remains fundamentally people-centric. As a result, this special issue brings together a collection of papers that highlight the critical role of human experience, public perception, leadership, and inclusivity in shaping infrastructure outcomes (theoretical and empirical). The selected contributions (spanning leadership, stakeholder engagement, transport systems, energy transition, and accessibility) demonstrate that successful construction and infrastructure delivery is as much about people as it is about technology.
Therefore, a systems perspective linking society, infrastructure, and organisations can be identified as a unifying theme across this Special Issue. This perspective adopts a multi-level framework (Figure 1) in which people are positioned at the centre of interconnected layers:
Societal level (macro): public perception, legitimacy, and trust
System level (meso): infrastructure performance and user interaction
Organisational level (micro): leadership, decision making, and workforce dynamics
The systems perspective model illustrates interconnected societal, system, organisational, and people-centred layers linking society, infrastructure, and organisations. At the centre, People includes Communities, Users, and Professionals. Surrounding this is the Organisational Level, Micro, containing Leadership and Culture, Decision-making, Workforce Dynamics, Operations and Service Delivery, and Capabilities and Learning. The next layer is the System Level, Meso, focusing on Infrastructure Performance and User Interaction. The outer layer is the Societal Level, Macro, representing Public Perception, Legitimacy and Acceptance, and Trust and Social Licence to Operate. A Drivers panel on the left lists Sustainability Imperatives, Digital Transformation, Demographic Change, Policy and Regulation, and Economic and Environmental Pressures. An Outcomes panel on the right lists Societal Value and Well-being, Resilient and Inclusive Infrastructure, Organisational Performance, and Sustainable Development. A lower Interconnections section highlights Continuous Engagement, Data and Insights Flow, Feedback Loops, Adaptive Response, and Shared Value Creation. The concluding statement explains that modern infrastructure systems are socio-technical ecosystems where technical, social, and organisational dimensions are deeply intertwined, with people at the centre.A systems perspective: linking society, infrastructure, and organisations (Source: Author, adapted from Ninan and Kundu (2026); Sexton et al.

This framing reflects the complexity of modern infrastructure systems, where technical, social, and organisational dimensions are deeply intertwined!
Public voice, perception, and project legitimacy
The growing importance of public perception is clearly illustrated in the work by Ninan and Kundu (2026). In this study on social media discourse surrounding PPP and non-PPP infrastructure projects demonstrates how digital platforms serve as powerful channels for community engagement and feedback. The findings reveal that PPP projects tend to attract more targeted criticism, particularly regarding pricing structures and operational performance, with scrutiny often directed towards private partners rather than public authorities (Ninan and Kundu, 2026). This reflects evolving expectations around accountability and transparency in infrastructure delivery. These insights point towards the need for continuous, data-driven stakeholder engagement, where social listening mechanisms are embedded into project governance.
Infrastructure systems and user-centred performance
In this paper, the human dimension of infrastructure is further explored through system performance and user interaction. Logeswaran et al. (2026) examine the performance of multi-modal transport systems, identifying key inefficiencies related to capacity constraints, passenger flow, and lack of integrated feeder systems. Their findings emphasise the importance of user-centred design and operational optimisation to improve system effectiveness. Similarly, Ivesøe Smith and Xydis (2026) explore how regional disparities and cost variability influence electric vehicle adoption in Denmark. Their analysis highlights how infrastructure provision, pricing mechanisms, and geographical inequalities shape consumer behaviour and impact the broader energy transition. Together, these studies demonstrate that infrastructure performance must be understood not only through technical metrics but also through the lens of user behaviour, accessibility, and experience.
Inclusivity and accessibility in the built environment
Moreover, the importance of inclusivity is highlighted in the study by Singh and Kumar (2026), which examines barriers faced by persons with disabilities in accessing urban public buildings in India. The findings indicate that accessibility challenges are influenced by a combination of physical infrastructure limitations, social factors, and user experience. Key barriers include inadequate vertical transportation systems and broader societal perceptions of disability (Singh and Kumar, 2026). These insights reinforce the need to embed universal design principles throughout the project lifecycle, aligning with global priorities such as UN Sustainable Development Goal 11. Accessibility must therefore be positioned as a core performance indicator in infrastructure development.
Leadership and organisational dynamics in construction
As a final note, at the organisational level, leadership remains a critical determinant of project success. Sexton et al. (2026) investigate leadership styles in the Irish construction industry, highlighting the adaptive and situational nature of leadership in complex project environments. Their findings suggest that effective leaders often employ a combination of styles, depending on the context, to motivate teams and deliver project outcomes (Sexton et al., 2026). This reinforces the importance of flexible and people-oriented leadership approaches, particularly in dynamic and uncertain construction settings. The study contributes to a growing body of knowledge that positions leadership as a key enabler of both project performance and workforce engagement.

Conclusion: towards a human-centred construction paradigm
This Special Issue highlights a critical shift in construction research and practice: the recognition that people are the central drivers of project success and societal impact. By examining leadership, public perception, infrastructure performance, sustainability transitions, and accessibility, the contributions collectively demonstrate the need for a holistic, human-centred approach to construction and infrastructure delivery. As the sector continues to evolve, integrating technological innovation with human insight will be essential to achieving sustainable, inclusive, and resilient built environments.
