Background: Construction work can negatively affect artisans’ mental health in the form of stress. This research investigated the effect of cognitive behavioral intervention on occupational stress among Nigerian construction trade artisans in the building construction sector. Methods: In this randomized controlled study involving 3 waves of data collection, 140 construction trade artisans who presented with high occupational stress symptoms at the study onset were assigned randomly to either a treatment condition (n = 70) or to a waitlist control condition (n = 70). The study involved pre-treatment and post-treatment assessments and a 3-months follow-up. The artisans’ occupational stress questionnaire and artisans’ dysfunctional thoughts at work scale were the data collection instruments. Results: Results revealed a significant effect of group on artisans’ occupational stress and dysfunctional thoughts at work. Also, significant effects of time on artisans’ occupational stress and dysfunctional thoughts at work were recorded. Finally, group × time interaction effects on artisans’ occupational stress and dysfunctional thoughts at work were significant. Conclusion: Cognitive behavioral intervention effectively reduced occupational stress symptoms and dysfunctional thoughts at work among Nigerian construction trade artisans compared with a waitlist control condition.

Purpose: This study aimed to examine the Effect of Indoor Environmental Quality (IEQ) on the Performance of Building Technology Lecturers in Nigerian tertiary institutions. Methodology: Three research questions guided the study in which survey research design was used. The entire population of the study was 216, comprising 84 building technology lecturers and 132 higher technical officers from six tertiary institutions in Nigeria. A 38-item questionnaire was used for data collection. The instrument was validated by three experts. Cronbach’s Alpha reliability method was used to determine the internal consistency of the instrument at a coefficient of 0.89. A total of 216 copies of the questionnaire were administered and 210 copies were retrieved, representing a 92% return rate. The data collected was analyzed using mean, standard deviation and t-test. Results: The study found out that there exist 5 items on how the indoor air quality (IAQ) affect building technology lecturers’ performance in Nigerian tertiary institutions, 5 items on how thermal comfort affect building technology lecturers’ performance in Nigerian tertiary institutions, 7 items on how building acoustics affect building technology lecturers’ performance in Nigerian tertiary institutions and 6 items on how ergonomics affects building technology lecturers’ performance in Nigerian tertiary institutions. The study also found 6 items on challenges of installing Indoor Environmental Quality (IEQ), facilities and 10 items on the ways of providing and improving Indoor Environmental Quality (IEQ), in Nigerian tertiary institutions. Practical Implications: Lecturers’ role on monitoring and maintenance of IEQ in offices could be enhanced through appointment of Desk officer in each faculty of the tertiary institutions. The Desk officer will liaise between the lecturers and maintenance unit of the institutions on IEQ issues. Originality/Value: The study concluded that improved indoor environmental quality has a tremendous impact on lecturer’s performance, comfort, workspace utilization and overall productivity.

The study appraised sensor technology as innovative pedagogy in building technology for improving safety management of building construction sites in Enugu State, Nigeria. Two purposes and two research questions guided the study. The design was a descriptive survey and the instrument used was a structured questionnaire. The population for the study was 65, comprising of42 Construction managers and 23 Site supervisors from registered construction company residents in Enugu state. Three experts face validated the Instrument and the Cronbach alpha reliability method was used to determine the internal consistency of the questionnaire items while 0.89 was obtained. The data collected were analyzed using mean and standard deviation. The study found 13 sensor technologies that can be used for safety management in construction sites in building technology. The findings of the study also revealed that sensor technology is an innovative pedagogy for improving safety management in construction sites. The study, therefore, recommended, among others, that construction managers should adopt the use of sensor technology for safety management in building construction sites, all construction workers should be trained on the use of sensor technology and the curriculum of building technology should be reviewed to accommodate the new innovation.

Bullying is a growing problem in the workplace. This study investigated the bullying experience of building and construction industry artisans. We employed a cross-sectional analytic design to study 240 artisans in respect of workplace bullying (WPB) experience using a self-report questionnaire. Percentage, mean and standard deviation were used for data analysis and interpretation. According to the study, a significant percentage (96.1%) of the artisans perceived themselves as victims of WPB within the past 6 months and these experiences also occurred once or more times weekly. WPB is a considerable problem among building and construction industry artisans in Nigeria. Further studies that can influence the construction industry to create valuable programs to minimize bullying among artisans are required.
