    Assessing the communication modes on quality and time performance of project delivery: A case study in Dormaa East District
    (2021-06-17) Mensah, Enoch Yaw; Owusu-Manu, De-Graft
    One of the major problems facing the Ghanaian construction industry is delays in the delivery of construction projects. Also, the qualities of workmanship of executed projects are most often questionable. Thus, it is significant to improve on schedule and quality performance in the Ghanaian construction industry so as to reap its full benefits to the economy. In 2011, a report by Building Research Establishment (BRE) indicated that, ineffectiveness and bad communication practices promote most defects in the construction industry. The study investigated into how communication affect quality and time performance of project delivery. An extensive literature review was conducted which aided in the development of a structured questionnaire to collect data from the respondents. Non-probability sample technique was used in deriving the sample size. Relative Importance Index (RII) technique and multiple regression were used to analyze the responses. It was realized that, face-to-face communication is the mostly used communication mode in Dormaa East District followed by telephone and memos and letters. Also, lack of education and training is the most significant challenge that affects communication followed by lack of motivation and language incompatibility. Poor planning and dispute and litigations showed significant relationship with schedule performance. However, bureaucratic interference showed a significant negative relationship with schedule performance. Excessive design changes and low project manager‟s competence showed significant relationship with quality performance. The results indicated that, there is a significant relationship between ineffective communication factors and quality problems in the Ghanaian construction industry. It was recommended that, employees should be educated on the significance of effective communication in an organization so as to enhance the organizational processes.

    (Sciendo - De Gruyter, 2023) Adesi, Michael; Owusu-Manu, De-Graft; https://orcid.org/0000-0003-3222-9531; https://orcid.org/0000-0001-5288-3210
    Brief introduction to the Problem: Construction accident studies often overlook the internal perspective of employees on site accidents' impact on corporate reputation. Purpose: This study investigates the effects of construction site accidents on corporate reputation from an internal viewpoint of stakeholders, focusing on employees. It also determines the extent of the association between site accidents and corporate reputation in middle-income economies. Design/methodology/approach: A quantitative approach was used, with 150 survey questionnaires administered to employees in construction firms using purposive sampling. Descriptive and inferential statistical tools, including the Pearson correlation and factor analysis, were used to analyse the results. Findings: Site accidents have 17 identified effects on corporate reputation, negatively impacting leadership, financial management, ethics, shareholder value, and sustainability. Originality: This study highlights the significant impact of construction site accidents on corporate reputation from an internal perspective of employees and identifies the need for more research on this issue. It has the potential to influence construction health and safety research focus, which has previously not addressed the issue of corporate reputation from an internal perspective.
