Technology has undoubtedly played a vital role in improving construction procedures and processes for many years. However, its application for health and safety monitoring and management has not been fully exploited in the Ghanaian construction industry. This study aims at exploring the current technologies essential for health and safety in the Ghanaian construction industry. Three specific objectives are set: (1) to identify the current health and safety technologies important in the Ghanaian construction industry; (2) to examine the level of utilization of the current health and safety technologies in the Ghanaian construction industry; (3) to identify the barriers to the adoption of the current health and safety technologies in the construction industry. A structured questionnaire is used to solicit the views of 123 construction professionals who double as health and safety officers in large construction firms in Ghana. The questions are developed through a critical comparative review of the related literature. The data are analyzed via descriptive and inferential statistics. The findings reveal that key among the current technologies important for health and safety in the Ghanaian construction industry are wearable safety devices, geographic information systems, sensing technologies, virtual reality, and BIM. The findings further reveal a moderate level of usage of the key technologies among construction professionals in Ghana. Key among the barriers to the adoption of these technologies for health and safety in the Ghanaian construction industry are the factors ‘excess costs related to acquiring new technologies’, ‘weak innovation culture’, ‘lack of continuous training of the workforce in adapting to the technologies’, ‘resistance to change with aging workforce’, and ‘little or no governmental support and regulations for the use of the technologies’. The findings from this study provide insight into the ever-increasing state-of-the-art technologies used in the construction industry.
PurposeThe absence of effective stakeholder engagement at the early planning and implementation stages impact projects negatively. However, the role of stakeholders in Sustainable Procurement (SP) is not well recognized and as such there is limited involvement of stakeholders in sustainable procurement of public (SPP) works. This research aims to examine the barriers to stakeholder engagement in SPP works.Design/methodology/approachA survey of 104 respondents from eight procurement entities of tertiary institutions in Ghana was undertaken and validated with seven procurement experts. After satisfying all the necessary tests of reliability of the survey instrument and sample size, the data was subjected to the Principal Component Analysis (PCA) to determine the critical barriers.FindingsThe study's results indicate that there are three cluster of barriers to stakeholder engagement in SPP works. They are organisational structures and knowledge driven factors, attitudinal and stakeholder fatigue and relational and information sharing processes.Practical implicationsThis study offers relevant data for policy makers, organisations and local communities in establishing controls against barriers to stakeholder engagement. Furthermore, this research presents policy makers with recommendations to improve communication and organisational policies in enhancing stakeholder participation in SPP works in Ghana and other developing countries.Originality/valueAlthough studies on SP has increased with time, issues such as obstacles to stakeholder engagement in SP remain unexplored. Empirical data presented in this study bridges the gap that exists on the barriers of stakeholder engagement in SPP works in the Ghana Construction Industry.
The participation of built environment (BE) professionals is essential in pushing the agenda of green buildings (GBs) in the construction industry. Considering willingness to pay (WTP) in light of these professionals plays a role in the management of the construction industry as one of the major energy consumers and emitters of greenhouse gases. This study, from an extended perspective of green building, seeks to examine the factors that influence Built Environment (BE) Professionals’ willingness to pay for green buildings in Ghana. A questionnaire survey was used to solicit the views of the professionals on the theme under investigation. Purposive and snowball sampling techniques were used to obtain 153 responses from BE professionals such as architects, quantity surveyors, construction managers, and project managers in Kumasi and Accra. Both descriptive (mean, standard deviation, and standard error) and inferential statistics (one-sample t-test) were used to analyze the data. The study revealed that perceived benefit stood out as the topmost factor that BE professionals consider in their willingness to pay for green buildings. This paper could serve as an eye-opener to aid in the development of strategies and influencing mechanisms to stimulate the interest of various groups of BE professionals in delivering a more environmentally friendly construction system. This study contributes to the state-of-the-art studies regarding willingness to pay for GBs. The global literature is largely focused on the willingness of household consumers/clients to pay for GBs to the detriment of the BE professionals, who play key role in GB developments, and encourage their adoption. The novelty of this study stems from the fact that it is the first time the views of BE professionals are examined when it comes to their willingness to pay for green buildings.
It is thought that there is a low level of awareness of key competencies that drive material waste reduction at the construction stage of a project which has led to the low impact of waste minimization in the construction industry. This study, therefore, explores the key competencies for driving waste minimization at the construction stage of projects. Twenty-four (24) key factors that drive CW minimization at the construction stage of projects were derived from a thorough review of existing literature. The research adopted the quantitative approach whereby a questionnaire survey involving 53 construction professionals was conducted. Factor analysis was the statistical tool employed for the analysis of the data gathered. The findings of the study revealed four major competencies that drive CW minimization: Awareness Competency (AC), Managerial Competency (MC), Personnel Ability Competency (PAC), and Communication Competency (CC). The implementation of the key competencies from the findings of the study is highly recommended for the achievement of low waste in building projects. In view of this, it is recommended that government should enact legislative and fiscal measures to instill waste management habits in the construction industry. Several studies have investigated strategies or measures for CW minimization. However, this study focused on the knowledge and skills of construction stakeholders as the main component of waste minimization competencies.
