Role of Construction Sector in Economic Growth: Empirical Evidence from Nigeria

The construction industry plays an important role in the economy, and the activities of the industry are also vital to the achievement of national socio-economic development goals of providing shelter, infrastructure and employment. It is clear that construction activities affect nearly every aspect of the economy and that the industry is vital to the continued growth of the economy. Surprisingly, the construction industry was left out from the list of major growth drivers of the economy. In order for construction to ably perform this role, there is a need to provide information on its economic value and its place in the overall economy of a country needs to be placed in perspective, if its function is to be fully understood. This study attempted to investigate the relationship between the construction sector and aggregate economy. Time series data from 1990 - 2009 on construction output and Gross Domestic Product (GDP) used for the study were extracted from the United Nation Statistic Division. This paper uses econometric techniques such as unit root test, cointegration test as well as Granger causality test to analyze the significance of construction linkage with the aggregate economy. The result indicates that construction output is Granger caused by GDP, while the construction output also granger causes the GDP. Both GDP and construction output lead each other by one year. The study concluded that the Nigerian construction sector is very important because of its capacity to lead the economy of Nigeria

Impact of Construction Health & Safety Regulations on Project Parameters in Nigeria: Consultants and Contractors View

The effectiveness of the construction industry can only be enhanced by repositioning the construction health and safety regulations to safeguard the health of the workers and the entire community. This paper seeks to assess the views of consultants and contractors about the impact of construction health and safety regulations in Nigeria. Data was collected using the questionnaire survey distributed among construction professionals and statistical tools employed include tables, percentages and mean score ranking. The study revealed that construction health and safety is still perceived to be more important than the traditional project parameters in the form of cost, time and quality. Designers perceive that an enhanced environment is the resultant impact of construction health and safety regulations while quantity surveyors see improved quality as having the resultant impact while contractors perceive improved maintenance as having the resultant impact on health and safety regulation. The study recommends that better attention is given to health and safety should as a project parameter and that related practice notes and guidelines should be evolved for all project stakeholders

Critical barriers to environmental management system implementation in the Nigerian construction industry

This is an accepted manuscript of an article published by Springer in Environmental Management, available online: https://doi.org/10.1007/s00267-021-01473-y The accepted version of the publication may differ from the final published version.The impact of different hazardous substances of the construction industry being released to the environment is alarming. This constitutes an adverse effect on the quality of life of construction workers and the populace at large. To reduce this menace, Environmental Management System (EMS) was put in place. Meanwhile, the implementation of EMS in the Nigerian construction industry (NCI) is not certain. This study, therefore, investigated the barriers to EMS implementation in the NCI to group them into a smaller form, i.e., fewer numbers. A questionnaire survey was developed and administered to construction professionals in Nigeria using a purposive sampling technique. The retrieved 106 copies of the questionnaires were subjected to both descriptive and inferential statistics such as mean score, standard deviation, analysis of variance test, post hoc test and exploratory factor analysis. An exploratory factor analysis was conducted three times to identify the critical barriers to EMS implementation in the NCI. The study findings reveal three main categories of barriers affecting EMS implementation, namely; (1) knowledge barrier; (2) process barrier; and (3) culture and management barrier. The study concluded that the three factors indicate the major cardinal barriers that could describe the impediment of EMS in the NCI. It was recommended that the training of construction professionals is important to enhance improvement culture in the NCI
