“…Ninety-three percent of the electric distribution substations (28/30) scored <75% compliance on housekeeping and 30% (7/30) were non-compliant (<100%) on fencing. Housekeeping is essential for fire prevention; however, it can easily deteriorate due to a lack of onsite supervision and maintenance [26]. Major factors that contributed to poor housekeeping were the visible weeds, leaking oil from the transformers and loose electrical parts on the ground in the electric distribution substations.…”

Annually, an estimate of 2.3 million workers die prematurely due to occupational injuries and illnesses. In this study, a risk assessment was conducted to evaluate the compliance of 132 kV electric distribution substations and proximal residential areas with the South African occupational health and safety Act 85 of 1993. Data were collected from 30 electric distribution substations and 30 proximal residential areas using a checklist. Distribution substations of 132 kV were assigned an overall compliance value of ≥80%, while a composite risk value of < 0.5 was assigned to individual residential areas. The Shapiro–Wilk test was used to check for data normality before multiple comparisons and the Bonferroni adjustment was applied. Non-compliances in electric distribution substations were as a result of poor housekeeping and inappropriate fencing conditions. Ninety-three percent of the electric distribution substations (28/30) scored < 75% compliance on housekeeping and 30% (7/30) were non-compliant (<100%) on fencing. Conversely, there was compliance in the proximal residential areas concerning the substations. Statistically significant differences were found when substation positioning and surrounding infrastructure (p < 0.00), electromagnetic field sources (p < 0.00) and maintenance/general tidiness (p < 0.00) were compared. A peak risk value of 0.6 was observed when comparing the substation positioning with proximal electromagnetic field sources in the residential area. Housekeeping and fencing in the distribution substations must be improved to prevent occupational incidents such as injuries, fire outbreaks, theft and vandalism.

“…Among the most significant causes were “delay in decision making,” “incomplete design and estimate at the time of tender,” “design change during construction stage,” “errors and omission in both drawings and in the bill of quantity,” “delay of material delivery” and “poor site management.” Banobi and Jung (2019) investigated the causes of delays of power construction projects. It was found that the major causes of delay of unsuccessful projects were “poor cost estimation,” “vandalism,” “late delivery of material and equipment,” “late procurement orders for material and equipment” and “additional work attributable to errors.” Jongo et al. (2019) looked at causes and effective mitigation strategies of time and cost overruns in public building projects conducted in Tanzania.…”

PurposeThe present study employs social network analysis (SNA) to demonstrate the extent to which various building information modeling (BIM) functions can be used to address significant issues faced by the Tanzanian public sector construction projects.Design/methodology/approachThis study adopted secondary data obtained from a comprehensive literature review on core BIM functions and the underlying issues faced by the Tanzanian public sector construction projects. This study then adopted SNA for associating the BIM functions with relevant construction issues.FindingsFor Objective 1, the findings revealed that BIM can address 68% of significant issues faced by the Tanzanian public sector construction projects. For Objective 2, the findings revealed that the identified functions mainly addressed issues in the early phases of the project. Finally, for Objective 3, the most effective function was “spatial coordination.”Research limitations/implicationsThis literature-based study does not fully capture both the current contextual issues faced by the industry and the BIM capability of stakeholders involved. In addition, this research does not distinguish between public project size and type which can influence the types of issues faced and consequently the use of BIM function. Accordingly, the research presented in this study needs to be complemented by on-the-ground feedback of industry stakeholders and needs to investigate how project size and type impacts the types of issues that emerge and the use of BIM.Practical implicationsWith respect to practice, the findings of the present study highlight key BIM functions practitioners can begin to target.Social implicationsIn Tanzania, public sector construction projects contribute greatly to social development of Tanzania's population. Owing to the current state of public sector projects underperforming and the negative impact the projects have on the country's development, an intervention measure such as BIM has the potential to enhance the effective and efficient delivery of these projects and thereby promote the social development of the country's population.Originality/valueWith respect to theory, this study demonstrates how core functions of BIM can be mapped with various construction-related issues in order to evaluate the efficacies of the BIM-based investments for improving overall performance in the public sector projects. With respect to practice, the method illustrated in the present study can be applied by policymakers and practitioners to identify core BIM functions to target to address pressing contextual issues faced by public sector projects in the respective contexts.

“…The study concludes that as the project environments become complex, state of the art approaches should be used in project scheduling as they are central to the construction projects' performance. Jongo, Tesha, Kassonga, Teyanga and Lyimo (2019) analyzed the mitigation measures in dealing with delays and cost overrun in public building projects in Dar-Es-Salaam, Tanzania. This study identified mitigation measures in dealing with delay and cost overrun in public building project, in which out of 25 mitigation measures, effective project planning and scheduling was ranked first; followed by controlling design changes, and effective coordination and communication between parties.…”

This study analyzed the effect of project scheduling management on performance of construction projects in Mombasa County, Kenya. The study targeted 175 contractors implement construction projects in Mombasa County. The contractors targeted were categorized as NCA5, NCA6, NCA7 and NCA8. This study adopted a cross-sectional survey design. Stratified random sampling method was used to select relevant respondents from across the board in the various categories of NCA contractors in Mombasa County. Structured questionnaires were used to collect primary data from respondents. Quantitative data was analyzed using SPSS version 26. From the findings, the study revealed that most contractors performed project tasks sequence to ensure effective use of resources. Also project managers finds the order of tasks that will take the least amount time. Further, the study found that constraints between tasks were taken into considerations and that the construction projects tasks are assigned baseline measures. Also project tasks are defined prior to construction commencement as most the respondents agreed and also the tasks of the construction projects are defined using sequencing tools. The study concluded that tasks dependencies of the project are effectively considered by the project leadership during project scheduling. Also Gantt Chart is prominently used by the project team to visualize project tasks dependencies and the construction projects task dependencies are well documented and that the critical path of the project task dependence is focused with resources. Also the schedule of the project tasks is communicated frequently to the project team and the communication of the schedule procedures is relayed horizontally stated and communication is centralized throughout the project life cycle as well as internal communication amongst the project team is always promoted throughout projects' life cycles. The study recommended that project resources should be scheduled systematically before the commencement of the project construction. The construction projects should be equipped with knowledgeable human resources. This would improve on the project deliverables such as timeliness, within budget and quality. The technological resources should be deployed in the construction projects as well as provision of sufficient financial resources.
