    Bridging the gap between health and safety performance and owner's satisfaction in construction projects adopting pro-environmental construction practices: role of economic performance
    (2023) Onubi, Hilary Omatule; Carpio, Manuel; Azian, Fatin Umaira Muhamad; Binwai, Pirmah
    The satisfaction of clients/owners, though very important as a determinant of construction project performance, has often been given very little attention in pro-environmental-related studies. To this end, this study's aim is to determine how owner's satisfaction (OS) can be realized via health and safety performance (HSP) and economic performance (EP) on construction projects that adopt pro-environmental construction practices (PCP) in Nigeria and to determine how the impact of HSP on OS can vary contingent on the level of EP. This study's aim was realized through data obtained from a survey of 249 construction projects and analyzed by adopting the partial least squares structural equation modeling (PLS-SEM) technique. The results of this study signify that HSP has a significant positive effect on OS; the nexus between HSP and OS is partially mediated by EP, while EP moderates the HSP-OS link with high EP producing the stronger effect. The practical contributions of this research emanate from the fact that its findings show that the existing gap between the level of HSP and OS is partly due to EP. Also, projects with high EP have a greater influence on the HSP-OS relationship. Therefore, to bridge the gap between HSP and OS in construction projects that adopt PCP, due attention should be given to EP.

    Bridging the Gap between Perceived Pro-Environmental Benefits and Pro-Environmental Behavior: Mediating Roles of Green Work Climate and Pro-Environmental Training
    (2023) Onubi, Hilary Omatule; Hassan, Ahmad Sanusi; Carpio, Manuel
    Recent initiatives from the government, nongovernmental organizations, and professional bodies in the Nigerian construction industry to encourage pro-environmental behaviors (PEBs) have created awareness on the benefits of engaging in PEB. However, PEB on construction sites in Nigeria remains low. This study explored the effect of perceived pro-environmental benefits (PPEBs) on PEB among construction site managers in Nigeria, and the mechanism through which PPEBs can lead to PEB through pro-environmental training (PET) and green work climate (GWC). A total of 257 usable responses were obtained from a survey of construction project managers and evaluated using the structural equation modeling method. The results obtained indicate that PPEBs had no significant effect on PEB, whereas PET and GWC fully mediated the relationship between PPEBs and PEB. This study's findings fill existing gaps in the literature and provide academicians, policymakers, and construction industry practitioners with in-depth knowledge of other variables such as PET and GWC, through which PPEBs can translate into PEB on construction project sites.

    Job satisfaction in green construction projects: antecedent roles of green work climate, pro-environmental construction practice and green human capital
    (EMERALD GROUP PUBLISHING LTD, 2022) Onubi, Hilary Omatule; Carpio, Manuel; Hassan, Ahmad Sanusi
    PurposeJob satisfaction (JS) of construction workers is important in determining the level of green construction project performance. Despite the importance of construction workers' JS in actualizing green construction projects' objectives, insufficient consideration has been accorded in green construction studies. This study aims to determine the link between green human capital (GHC), pro-environmental construction practice (PCP), green work climate (GWC) and JS. Precisely, the purpose of this study is to investigate the mediating role of GWC on the GHC and PCP relationship while analysing the moderating effect of GWC on the relationship between PCP and JS.Design/methodology/approachThis research's data were collected through a survey questionnaire with 272 useable responses obtained. The partial least squares structural equation modelling (PLS-SEM) technique was used in the study's data analysis.FindingsThe findings of this study indicate that GHC was positively related to PCP; GWC had a significant mediating effect on the GHC-PCP relationship; PCP had a significant positive effect on JS; and GWC had a significant moderating effect on the PCP-JS relationship with high GWC yielding the greater effect.Practical implicationsThis study gives a clearer picture of how GHC can lead to the adoption of PCP through GWC and translate to JS, thus providing stakeholders with the required information on firm-based initiatives that can promote the needed green behaviour on the construction site.Originality/valueThe originality of this study lies in its contribution to both theory and practice as it provides greater insight into PCP alongside its antecedents and outcomes as it relates to the JS of construction project/site managers.
