Risk and Safety Management in the Construction Industry: A Case of Tamale Metropolis, Northern Region (Published)
The paper examines the key factors that influence risk and safety performance of construction sites, the effects of accidents on construction site and the measures that will improve risk and safety performance on construction sites in the Tamale Metropolis in the Northern Region of Ghana. Three research questions were formulated. The study adopted descriptive research that is mixed methodology approach. The research instruments employed were self- administered questionnaires, interviews and observations which were used in collecting primary data from the selected construction firms. The population of the study was two hundred and thirty (230) selected individuals. They consist of site supervisors (60), site engineers (60), architect (30), consultants (20) and general foremen (60) in the Tamale Metropolis of Northern Region of Ghana. Interview guide were also sent out to reach thirty (30) Project Managers of the registered Ghanaian contractors and an observations were made in six (6) different project sites to get the right information about risk and safety management in the construction industry .Stratified random and non-proportional probability sampling techniques were employed for the study. The findings of the study on factors that influence risk and safety performance revealed some important factors which include; lack of implementation of mandatory PPE policy on site, inadequate and safe means of access to and from at workplaces, difficulties in accessing risk and safety records due to restricted working conditions, and less or no lighting in confine areas on site to ensure risk and safety management. The findings of the study also gave the effects of construction sites accidents and their consequences; on fatal accidents, day’s work is suspended, construction companies pay huge sums of compensation, some accidents lead to loss of lives. The study made some recommendations which, if adopted, will lead to significant improvements in the risk and safety performance of construction companies in Ghana.
This study was carried out to identify the factors influencing the performance of construction projects in Akure, Nigeria. A questionnaire survey was conducted and forty six (46) factors were identified, categorized into eight (8) groups, evaluated and ranked according to participants’ perspectives. Fifty (50) questionnaires were distributed as follows: 12 to clients, 18 to consultants and 20 to contractors. The outcome of these analyses showed that all the respondents agreed that construction projects were influenced by all the forty six factors indicated by the questionnaire. However, the analysis indicated that the top ten (10) factors that have the highest average index showed how these factors are affecting construction projects. Based on these findings, this study recommended that contractors’ progress payment should be made on time as well as minimizing change orders during construction to avoid delays. Also, consultants should give full commitment to monitor the project progress and ensure the work was according to specifications and satisfactory quality; meeting owner needs and expectation within the project budget and stipulated time. Finally, continuous coordination and relationship between project participants were required through the project life cycle in order to ensure project performance.

Assessment of the Relationship between Risk Allocation and the Performance of Building Infrastructural Projects in Nigeria (Published)
Risk in building infrastructural projects is the exposure of construction activities (related to building) to economic loss, due to unforeseen events or foreseen events for which uncertainty was not properly accommodated. With building infrastructural projects becoming increasingly complex and dynamic in nature as well as the introduction of new procurement methods, many stakeholders are interested in an approach that will enhance project performance within their organizations. The study assessed the relationship between risk allocation and performance of building infrastructural projects. A total of one hundred and eighty copies of questionnaire (180) were administered on randomly selected stakeholders (comprising construction clients, consultants and contractors and insurance companies), out of which one hundred and fifty (150) was found valid and applicable for this study, and this constituted 86.6% of the sample size. Statistical techniques employed for data analyses were percentage of Relative Importance Index (%RII), Cronbach’s alpha reliability scale Test, T- test and Spearman’s rho correlation analysis. The analyses revealed that clients, consultants, contractors and insurance firms risk allocation affect project performance. Risk elimination by management was ranked first among the tools used to minimize construction projects risk. All the results of the Cronbach’s alpha reliability test were above 0.5 which indicated that the items were reliable for the measurement of risk allocation and risk factors. An average Spearman’s rho correlation coefficient of 0.6912 showed that risk allocation among stakeholders was significant and directly related to project performance at 0.05 level of confidence. The Paired samples T-test on risk allocation and project performance revealed that there was no significant difference between risk allocation and project performance. It was concluded that there was a positive relationship between building infrastructural risk allocation and project performance. The study therefore recommended that building infrastructural stakeholders should triangulate and use multiple models during the feasibility and viability planning stage of building infrastructural projects in order to reduce pit hole at the construction stage.
Effect Of Project Model Change On Project Performance In Rwanda: A Case of World Vision’s Village Savings Loan Associations Project Model in Nyamata Area Development Programme (Published)
This research will focus on the impact of project model change on project performance: a case of Village savings loans and associations in Nyamata Area development programme of World Vision Rwanda. This model of project called VSLAs has been initiated by Care International and World Vision Rwanda (WVR) is applying the model with the purpose of creating self-reliance and auto financing capacities among poor families from Nyamata Area Development programme. VSLAs project members have been able to mobilize their own savings and run income generating activities to satisfy their basic needs without relying on external support and then enjoy the empowerment and sustainability of VSLAs project interventions.The overall purpose is to find out if VSLAs project model is contributing to high project performance in the community of Nyamata Area Development Programme. The objectives of the study are to assess the economic status of the beneficiaries involved in VSLA , to examine family dynamics/social impact for or members of the VSLA, to examine how VSLA has impacted the environment and to analyse how VSLA has alleviated dependency in Nyamata ADP. The target population is 1250 members of the 50 VSLAs groups in Nyamata Area Development Programme. The proposed research design is correlation research whichgives an estimate as to the degree of association between the variables. A simple random sampling technique will be used to select members of VSLAs to be interviewed on how they have been positively affected by being VSLAs members. A sample size will be 120 members of VSLA groups determined using AllainBuchardformular. Both primary and secondary data will be used in this research study. The primary data will be collected directly from the respondents by use of questionnaires, interviews and observation. Secondary data on the other hand will be collected by reviewing Nyamata programme reports, and project design documents about VSLAs formation and how it improves project performance in the targeted area.Concerning the research instruments, the researcher will use closed-ended and open-ended questionnaires directed to members of VLSAs.Descriptive analysis will be used to summarize the characteristics of the respondents, the descriptive statistics will involved the use of mean, frequency, percentages and standard deviation on how VSLAs members have been impacted in creating IGAs, green environment, paying school fees , making decision in the family, acquiring new assets and paying health insurance. The results from this research will be presented in form of tables and bar graphs. The researcher hopes that this study will help World Vision Organization to replicate this project model to all other remaining 28 Area Development programme in Rwanda
