    ASSESMENT OF THE ADOPTION OF GREEN BUILDING TECHNOLOGY TECHNIQUES ON WORKERS' PERFORMANCE IN PUBLIC OFFICE
    (Multidisciplinary Acdemic Conference,, 2024-12-30) Yunusa A & Alumbugu, Polycarp Olaku
    Green Buildings (GB) can improve occupant satisfaction, productivity and overall wellbeing (Quandung et. al.; 2020). Poor adoption of GBT has led to poor indoor air quality in building in Nigeria, resulting in negative impacts on occupants' health and productivity (Oyedepo, 2017). The Nigeria Government has made efforts to promote the adoption of Green Building Technology (GBT) for sustainable development by establishing Nigerian Green Building Council (NGBC). In this light, this paper seek to assess effect of the adoption of green building technology on workers' performance in public office buildings in Abrija, Nigeria by adopting the quantitative research approach. Data were collected with the use of structured questionnaires which were administered to 105 purposively sampled respondents who are both construction and non-construction professional public servants. Analysis of data was undertaken with the use of descriptive (Mean Item Score, MIS) and inferential (Spearman Rank correlation analysis) statistical techniques. Findings from the study revealed that the techniques involved in the adoption of GBT for public office buildings most adopted are "Daylighting" (MIS = 4.18) and "Direct solar gain" (MIS = 4.04). The most significant perceived effects of adoption of GBT on performance of workers in public office buildings are "GBT results in a high-quality" (MIS = 4.03) and "GBs help to reduce the demand for new power plants" (MIS = 3.91). There exists a strong, positive and significant relationship between the adoption of Indoor Air Quality/Lighting and workers' satisfaction in public office buildings in Abuja (r = 0.474/0.420; p = 0.000). The study concludes that the impact of GBT on workers' performance in public office buildings in Abuja is significant and can enhance healthier working environment and maximum output for office workers. It was therefore recommended that construction firms to collaborate with other stakeholders to set up mechanism for enhancing the adoption of GBT for public office buildings in Abuja.

    Understanding a Worker Recruitment as a Practice of Informality in Construction Work Packages
    (Proceedings 40th Annual ARCOM Conference, 2-4 September 2024, London South Bank University, UK. Association of Researchers in Construction Management, 411-420., 2024-09-04) Olubajo, Oluseun Olukemi; Daniel, Emmanuel Itodo
    Research into the recruitment of workers in construction tends to focus on the relationship between operating environments and informal recruitment of a worker. A second thread compares the informal and formal sector of the construction market. However, detailed understanding of how workers are hired and the role of objects in projects executed informally is limited. This study explores how objects feature when workers are engaged informally around specific work packages. A social practice approach is adopted, and practices enacted with workers recruited with minimal compliance to formal housing regulations are studied. Data is obtained through interviews and observations in a building project in Lafia, Nigeria. The results reveal that objects prefigured in hiring workers for different work packages which enabled construction practitioners to do four things: carry out a situated assessment, estimate the volume of work, negotiate verbal agreements, and coordinate work. This study argues that objects enable project parties to enter verbal agreements or invisible contracts.
