What enables climate-responsive and resource-efficient office buildings in a small island developing state? a stakeholder-weighted readiness gap analysis
(Department of Building Economics, 2026) Bookauram-Nahullah, S; Fernando, NG; Jowkar, M; Waidyasekara, KGAS; Jayasena, HS; Chandanie, H; Tennakoon, GA
Climate-responsive and resource-efficient office buildings, often described in practice as green office buildings, are increasingly promoted in Small Island Developing States (SIDS). However, there remains limited understanding of how policy, finance, skills, and supply conditions interact to constrain adoption, as the literature largely focuses on barriers and drivers rather than readiness as a systemic condition. This study aims to examine what enables such buildings in Mauritius through a systems-informed, stakeholder-weighted readiness gap analysis. A mixed-methods approach combined 33 survey responses with five expert interviews. Survey respondents were regrouped into four stakeholder clusters such as developer/owner, government/policy, commercial/advisory, and technical delivery. Weighted Likert-scale responses were normalised into four readiness domains: market and finance, technical and supply, policy and institutional, and collaboration and delivery. Interview evidence was coded into causal relationships to produce a qualitative system map and identify reinforcing adoption traps and leverage points. The largest weighted gaps were found in market and finance readiness (0.735), technical and supply readiness (0.666), and policy and institutional readiness (0.652), while collaboration and delivery showed a lower but still material deficit (0.449). By contrast, respondents expressed strong support for feasible implementation priorities, particularly flood resilience (0.860), life-cycle assessment (0.852), daylighting (0.843), rainwater harvesting (0.843), passive cooling and efficient air-conditioning (0.834), and digital technologies (0.831). The findings show that the main challenge is not the absence of technical pathways, but weak enabling conditions. The paper contributes a multi-stakeholder study and a practical readiness-to-action framework for scaling uptake in SIDS office building markets.

Withstanding supply chain vulnerabilities in off-site construction logistics: a narrative review and 3d visualisation
(Department of Building Economics, 2026) Sandaruwan, WMDY; Sandanayake, YG; Ekanayake, EMAC; Tennakoon, GA; Waidyasekara, KGAS; Jayasena, HS; Chandanie, H; Tennakoon, GA
Logistics operations challenges in Off-Site Construction (OSC) trigger Supply Chain Vulnerabilities (SCVs), highlighting the need for a better understanding of appropriate Withstanding Measures (WMs). Existing research often lacks an integrated mechanism to systematically map SCVs and WMs. This limits decision-makers’ ability to understand interdependencies and prioritise responses effectively. As a result, there is a need for a visualisation model which also provides structured analysis of the relationships between SCVs and WMs. Therefore, this paper focused on developing a Three-Dimensional (3D) visualisation model to map SCVs and their corresponding WMs. Initially, a narrative literature review approach was employed to identify the SCVs in OSC and their relationships with WMs. A total of 30 papers were s selected through structured screening using predefined inclusion and exclusion criteria. Total of 73 SCVs and 98 WMs both across six thematic categories were identified. Based on the outcome of the literature review, the model was developed using CodeSandbox web development platform. The findings reveal that the integration of Geographic Information Systems (GIS) into Building Information Modelling (BIM) enables the mitigation of the highest number of SCVs. However, 61.64% of the identified SCVs are addressed by only a single WM, indicating limited exploration of WMs in these areas. Therefore, this study offers a novel contribution by developing a 3D visualisation model, addressing a critical gap in both relational mapping and visual decision-support in OSC Supply Chain (SC) logistics.

Workplace design and Gen Z retention: a social sustainability perspective in Sri Lanka
(Department of Building Economics, 2026) Ranathunga, SN; Dissanayake, P; Sathsarani, WNKBNA; Waidyasekara, KGAS; Jayasena, HS; Chandanie, H; Tennakoon, GA
The Sri Lankan corporate sector is currently grappling with a significant talent retention crisis, particularly among Generation Z (Gen Z) employees who increasingly prioritize the quality of their physical work environment over traditional incentives. While workplace design is frequently evaluated for space efficiency and productivity, its role as a driver of "Social Sustainability" specifically through human capital retention remains under-investigated in the built environment literature. In this context, Job Embeddedness, which explains why employees remain in organizations through their perceived fit with the job, social links within the workplace, and the sacrifices associated with leaving, provides a useful theoretical lens for understanding employee retention. This paper proposed a conceptual framework to addressing the relationship between Workplace Design and Turnover Intention mediated by Job Embeddedness (JE) in gen Z employees working in Sri Lanka. The paper combines the Generational Cohort Theory and the JE Theory to come up with such important design dimensions as flexibility design, biophilic integration, relaxation areas design and technological resilience which creates such psychological aspects of the organization as “fit”, “Link” and “sacrifice”. The expected outcomes are anticipated to equip facility managers, architects and corporate stakeholders with evidence-based design strategies to convert office spaces into social anchors. Finally, the study will play a role in the development of built environments that can enhance the social sustainability and long-term stability of Sri Lankan workforce within the unstable economic environment.

A Scientometric analysis of construction value management research: a 25-year review
(Department of Building Economics, 2026) Abeydeera, LHUW; Wadu Mesthrige, J; Maqsood, T; Chandani, GGN; Waidyasekara, KGAS; Jayasena, HS; Chandanie, H; Tennakoon, GA
This study presents a Scientometric analysis of construction Value Management (VM) research to map the intellectual structure, knowledge evolution, and emerging trends within the field. Despite the growing body of VM literature, a comprehensive understanding of its development, influential contributors, and research directions remains limited. To address this gap, CiteSpace was employed to analyse 400 publications indexed in the Web of Science Core Collection between 2001 and 2026. The analysis incorporated document, author, and country co-citation techniques to identify influential publications, collaboration patterns, knowledge clusters, and thematic evolution within the construction VM domain. The findings reveal a substantial increase in research activity over the past decade, indicating the growing importance of value-based approaches in construction management. The knowledge domain is characterised by strong research clusters centred on project performance improvement, value optimisation, and implementation-related studies, while developed countries continue to dominate research output and influence. The results further indicate an emerging shift towards sustainability-oriented VM, digital technologies, and data-driven decision-making approaches. By providing a comprehensive knowledge map of construction VM research, this study contributes to a deeper understanding of the field's intellectual foundations and development trajectory. The findings offer valuable insights for researchers and practitioners and establish a foundation for future investigations into value-based approaches in the construction industry.

A Study on legal and regulatory framework for entertaining unsolicited proposals to successfully implement PPPS in Sri Lanka
(2026) Fernando, PG; Kulatunga, U; Thayaparan, M; Hadiwattege, C
Governments around the world have sought to involve the private sector in the delivery of public services that have customarily been within the public authorities’ domain through alternatives. Public Private Partnership is one of such alternatives. In practice, Public Private Partnership initiatives can be initiated through either solicited or unsolicited approaches, and in recent years, the adoption of unsolicited Public Private Partnership has grown significantly in both developing and developed countries, as it harnesses the unique ideas and innovations of the private sector. The absence of a strong legal and regulatory framework has been identified as a major challenge to unsolicited Public Private Partnerships worldwide, including in Sri Lanka. Thus, this study aims to establish a legal and regulatory system to streamline unsolicited Public Private Partnerships in Sri Lanka. The study commenced with a comprehensive literature review to synthesise current knowledge within the research area and to define the research problem. Furthermore, the process of unsolicited Public Private Partnership was identified, and a theoretical grounds pertaining to unsolicited Public Private Partnership were identified. Subsequently, from an interpretivist philosophical perspective and adopting an abductive research approach, the data was collected through desk research review and semi-structured interviews conducted in four rounds of Delphi surveys. The data analysis carried out using content analysis, with cognitive mapping employed to depict the issues, recommendations, and reforms proposed by respondents during the Delphi survey. Finally, reformed framework was developed to streamline existing legal and regulatory framework of unsolicited Public Private Partnership framework. The developed framework provides comprehensive guidance for both private and public sector organisations concerning the formal procedures for unsolicited Public Private Partnership and the relevant regulatory authorities, from initiation through to award. The enhanced framework removed institutional barriers, allowing the private proponent to submit a proposal that satisfied the requirements of government agencies
