The Impact of Group Incentives on Construction Workers’ Performance in Nigeria (Published)

This study was designed to determine the impact of group incentives on construction workers’ performance. The study was conducted with data from questionnaire retrieved from fifty one construction professionals in Ibadan and Lagos, Nigeria. Twenty four possible impacts on workers extracted from literature were presented in the questionnaire for evaluation using a Likert sale of 1-5 for determining the relative importance of these effects. In the overall rankings of the types of group incentives using Analytical Hierarchical Process (AHP), goal sharing ranked the highest as the types of group incentives used in Nigeria. The result of the Factor analysis revealed social effects, effects of motivation, effects due to autonomy, workers’ behavioural effects and job dissatisfaction effects as the principal factors. The influence of social effects to motivate workers to improve on their productivity explains its usage as a type of group incentives.

Assessment of the Impact of Musculoskeletal Disorders on Nigerian Construction Workers (Published)

The purpose of the study is to assess the impact of construction activities as construction work entails non-ergonomic activities, range of in-situ work at various levels and construction workers; complain of pain, retire early from work, are frequently absent, are required to handle materials manually resulting in poor productivity as contractors are required to execute designs and excessive material wastage occurs. The focus is on reducing the impact of work related musculoskeletal disorders (WMD’s) among construction workers through contractor’s perception thereby creating effective and healthy construction workplaces. Given that the general contractors (GCs) responded relative to both general contractor (GC) and sub-contractor (SC). The impact of construction activities on construction workers in the Nigeria construction industry as it precipitates into WMDs affects the rate of productivity. The paper uses historic data on unfavourable ergonomic practices and quantitative survey method (based on a designed questionnaire) to establish a criterion for reducing WMD’s in construction by providing an effective strategies to promote construction workplace health and safety. The study establishes various interventions on factors that negatively impact on the health and safety of construction workers. Based on the findings from empirical survey and the survey of literature, the study tends to establish a work organization that can influence process and activities in the construction industry through designing of work place to ameliorate the prevalence of musculoskeletal disorder among its workers. Furthermore, the contractors’ perspective approach for health and safety as a panacea to reducing WMD’s is established. The information provides an insight into the contribution to safety and health of construction workers. The study establishes various interventions on factors that negatively impact on the health and safety of construction workers.

COMPARATIVE ASSESSMENT OF SAFETY CLIMATE OF CASUAL AND PERMANENT CONSTRUCTION WORKERS IN SOUTH-EAST NIGERIA (Published)

The use of flexible work arrangement outside the array of standard work arrangement has been linked to high rate of accidents on construction sites and unsafe behaviours. To this end, this study examines and compares the safety climate of casual and permanent construction workers with a view to ascertaining if there is any disparity in their responses to safety issues on site, the causes and the implications on the industry and society as a whole. The study was a survey research. The respondents were site operatives which were randomly selected from 80 construction sites across the South East Nigeria. A total of 861 questionnaires were duly completed, returned and found suitable for analysis out of 1200 issued, representing a response rate of 71.75%. The data collected were statistically analyzed using ONE WAY ANOVA at 5% (0.05) significance level. The study established that there is significant disparity in the safety behaviours of casual and permanent construction workers on sites due to perceived difference in the level of organizations’ safety obligations in terms of management commitment, workers involvement and safety education and training which arises due workers’ job nomenclature . It recommended a holistic readjustment in the employment system to close the gaps between casual employers and full time employers in terms of management commitment, workers involvement, education and training, welfare benefits, basic salary, working condition, etc (equal treatments) as its being practiced in New Zealand through the labour loading.

Appraising the Influence of Cultural Determinants of Construction Workers Safety Perception and Behaviour in Nigeria (Published)

Health and safety has been a source of concern to the performance of construction sector in Nigeria. The high rate of accidents and injuries occasioned by workers acts and perceptions attests to this concern. This paper assesses the cultural factors that influence the behaviour and perceptions of construction workers towards safety in South-East Nigeria. It provides a framework for incorporating cultural elements in issues relating to construction business. The study employed the survey research method for the investigation. Structured questionnaire was administered to a sample of site operatives and management staff involved in construction projects in the study area. Responses were analyzed using SPSS 16.0; mean score index and standard deviation to ascertain the influence of cultural elements on workers behaviour and perceptions. The study revealed that five cultural dimensions affect the way construction workers perceive and act towards safety. Respondents agreed that three dimensions (collectivism, uncertainty avoidance and long term orientation) promote safe behaviours and perceptions of workers, while power distance and masculinity promote unsafe behaviours and perceptions towards safety in construction. The study advocates adequate consideration of workers cultural values and beliefs in every construction business, especially those that promote safe behaviours and perceptions in the construction process.
